Patients are inquiring about  mini-incision primary total hip arthroplasty  with increasing frequency . There are no published r and omized controlled trials to substantiate cl aims that the mini-incision direct lateral approach is better than a st and ard approach . The purpose of our study was to review our initial experience with the mini-incision technique through the direct lateral approach , with the intent of implementing a r and omized controlled trial if the approach could be shown as safe and effective . Of importance was determining if there is any difference in component positioning and if there is any difference in intraoperative or postoperative complications between the two groups . We retrospectively compared a consecutive series of 87 primary total hip arthroplasties . Thirty-four total hip arthroplasties were done using a mini-incision direct lateral approach . The mean abduction angle was 45 ° for both groups . The femoral stem alignment was within five degrees of neutral in 97 % of the mini group and 94 % of the st and ard group . There were no dislocations , infections , neurologic or wound complications . There were no differences in medical complications or blood transfusions . A significant decrease was found regarding body mass index , which reflects the bias in patient selection and lack of r and omization . We conclude that it is safe to continue further study with this approach because as there was no increase in complications or component malpositioning . Level of Evidence : Therapeutic study , Level III ( retrospective comparative study ) . See the Guidelines for Authors for a complete description of levels of evidence Twenty patients who underwent total hip arthroplasty were r and omly allocated to have surgery through a mini incision of < or = 8 cm ( mini-incision surgery [ MIS ] group , n = 10 ) or a st and ard incision of 14 cm ( st and ard group , n = 10 ) . A laser Doppler flowmeter was used to measure the intraoperative blood flow of the skin . The measurements were performed at 2 regions , specifically , anterior and posterior regions across the middle points of skin incision . The measurements were taken before making the incision and after implantation . As a control , the skin blood flow over the anterior superior iliac spine was measured . After implantation , mean skin blood flows at both regions in the MIS group were significantly decreased by 32 % and 33 % . However , the corresponding flows in st and ard group and control regions were constant during operation Objective : To compare the results of single-incision minimally invasive total hip replacement ( ≤ 10 cm ) to st and ard-incision ( 16 cm ) total hip replacement in the early postoperative period with respect to functional and mobilizing ability ( transfers , mobilizing , walking and stair assessment ) . Setting : Orthopaedic wards of a regional orthopaedic centre . Subjects : Two hundred and nineteen total hip replacement patients were tested between December 2003 and June 2004 . Interventions : Patients were r and omized to either total hip replacement through a minimally invasive ( ≤ 10 cm ) or st and ard incision ( 16 cm ) . A single surgeon performed all procedures using the same type of component fixation . Postoperative physiotherapy assessment and treatment was st and ardized . Analgesia was also st and ardized . All patients , physiotherapy staff and assessors were blinded to the incision used . Main outcome measures : Patients were tested two days post operatively and were assessed for the following activities : transfer from supine to sit , transfer from sitting to st and ing , mobilizing , ascending and descending stairs and weight-bearing . Results : The shorter incision offered no significant improvement in patient ability in relation to transfer from lying to sitting , transfer from sitting to st and ing , mobilizing or weight-bearing . Ascending/descending stairs gave a total time for the minimal incision of 38.7 s against 40.8 s for a st and ard incision . There was no difference in walking velocity between the st and ard incision and minimal incision groups two days post operatively ( minimal incision = 0.26 m/s versus st and ard incision = 0.26 m/s ) or six weeks post operatively ( minimal incision = 0.90 m/s versus st and ard incision = 0.93 m/s ) . There was no difference between groups with respect to walking aids at six-week review . The mean length of stay for the minimally invasive approach was 3.65 days ( SD 2.04 ) against 3.68 days ( SD 2.45 ) for the st and ard approach . This was not significantly different . Conclusion : Total hip replacement performed through a minimally invasive incision of ≤ 10 cm compared with a st and ard incision of 16 cm offers no significant benefit in terms of the rate or ability of patients to mobilize and perform functional tasks necessary for safe discharge UNLABELLED In arthroplasty the term " minimal invasive " not only refers to the length of the skin incision but more so to its soft tissue and thereby muscle-protecting features . STUDY AIM The aim of this study is to compare the early postoperative mobilisation and rehabilitation of the different surgical approaches in cementless total hip arthroplasty . METHODS 27 patients underwent a total hip replacement ( Trilogy cup , MAYO stem ) via a ventral minimal invasive approach ( one incision technique ) ( MIS group ) . 23 patients underwent a total hip replacement with the same implant via a anterolateral transgluteal approach ( st and ard group ) . We evaluated the Harris Hip Score ( HHS ) , the visual analogue scale ( VAS ) for pain and patient satisfaction preoperatively as well as 3 days , 10 days , 6 weeks and 3 months postoperatively . RESULTS After 3 and 10 days the MIS group showed better scores for pain , gait and mobilisation as well as for the overall HHS compared to the st and ard group . These differences could not be shown 6 weeks postoperatively . The MIS group had a significantly higher rate of complications with 22 % transient impairment of the lateral cutaneous nerve . CONCLUSION The patients of the MIS group showed a better mobilisation and rehabilitation during the early postoperative period . This can be attributed to the lessened intraoperative damage of to soft tissue and especially muscle damage . Due to the increased rate of nerve irritations , we modified our surgical approach . The minimal invasive approach to modern hip joint arthroplasty remains a non-st and ard technique . Compared to the st and ard approach it carries additional risks ( like nerve damage and malpositioning of the implants and thus should remain in the h and s of the experienced orthopaedic surgeon in specialised orthopaedic centres AIMS Our primary aim was to evaluate whether there is really less bleeding in patients for whom the minimally invasive posterior approach is used in comparison with the direct lateral approach for primary total hip arthroplasty . Our secondary aim was to evaluate the clinical functional results after six months as well as the postoperative radiographic result . METHODS In a comparative non-r and om prospect i ve study , 76 adult patients underwent elective total hip arthroplasty using one of two approaches . The minimally invasive posterior approach ( 34 cases ; mini-incision group ) was compared with the st and ard direct lateral approach ( 42 cases ; control group ) . RESULTS Lower total estimated bleeding ( means of 1083.5 ml versus 1682.3 ml ; p < 0.001 ) and lower intraoperative bleeding ( means of 745.6 ml versus 1282.8 ml ; p < 0.001 ) were found in the mini-incision group . There was , however , no difference in the volume of blood drained after the operation ( means of 340 ml and 399 ml ; p = 0.77 ) . There was also a difference between the two groups regarding the need for allogenic transfusion ( 8.8 % in the mini-incision group versus 28.6 % , p = 0.02 ) . We observed a better clinical result in the mini-incision group ( p = 0.002 ) despite the lack of difference between the two groups in relation to the radiographic result . DISCUSSION Our results draw attention to the possibility that other authors may have underestimated blood losses when using minimally invasive approaches . CONCLUSION The minimally invasive approach gave rise to a positive final impression with regard to lower blood loss Patients without prior hip surgery and body mass index lower than 30 undergoing primary total hip arthroplasty were eligible to participate in a r and omized prospect i ve study comparing a minimally invasive with a st and ard approach . The patients were r and omized  to receive incisions  of 8 cm ( group A , n = 28 ) or 15 cm ( group B , n = 32 ) . The groups were similar demographically . Patients in group A had significantly less intraoperative blood loss ( P < .003 ) and less total blood loss ( P < .009 ) . Fewer patients in group A limped at 6 weeks ( P < .04 ) . Operative time , transfusion requirements , narcotic usage , length of hospital stay , achievement of rehabilitation milestones , cane usage , and complications were similar in both groups . There was no difference between the groups at 1- and 2-year follow-up . Compared with a st and ard incision , patients who underwent a minimally invasive total hip arthroplasty demonstrated decreased blood loss and limped less at 6-week follow-up The purpose of this prospect i ve r and omized study was to compare the early results of primary total hip arthroplasties performed with a minimally invasive technique or a st and ard technique . A consecutive series of 70 patients who underwent primary bilateral simultaneous total hip arthroplasties was studied . All procedures were performed through a posterolateral approach . Operative times and duration of hemovac drains were significantly shorter in the group with a minimally invasive technique ( P < .05 ) . However , there was a risk of infection when using this technique . There were no any late transfusions in any of our patients postdischarge . This minimally invasive technique did not offer any advantages because the results were not different , and in our h and s , it increased our infection rate BACKGROUND Minimally invasive total hip arthroplasty is purported to allow an improved and faster rehabilitation in the immediate postoperative period because of reduced soft-tissue damage compared with total hip arthroplasty performed with use of a st and ard approach . In the present study , a minimally invasive approach was compared with a traditional st and ard approach in terms of the effect on gait kinematics as demonstrated with gait analysis and electromyography . METHODS Twenty r and omized patients who underwent a primary total hip replacement with use of a minimally invasive modified Watson-Jones approach ( minimally invasive group ) were compared with a group of twenty patients who underwent a total hip arthroplasty with use of a st and ard transgluteal Hardinge approach ( st and ard group ) . All patients received the same cementless implant , inserted with use of st and ard instruments , and all operations were performed by a single , experienced surgeon . The patients were evaluated with use of three-dimensional gait analysis and dynamic electromyograms at three time points : preoperatively , ten days postoperatively , and twelve weeks postoperatively . Temporospatial and joint-kinematic parameters were evaluated . RESULTS There were no significant differences between the two groups with regard to the temporospatial variables of velocity , cadence , step length , and stride length at any tested time point . With regard to the range of motion of the operatively treated hip , the minimally invasive group had a smaller decrease at the ten-day time point in comparison with the st and ard group . However , this finding was not significant . The reduction in the range of motion was mainly caused by reduced hip extension . A compensatory increase in the pelvic tilt was observed in both groups . One patient in the st and ard group showed a positive Trendelenburg gait ten days postoperatively ; it had disappeared completely at the twelve-week time point . CONCLUSIONS With regard to gait kinematics in the early postoperative period ( three months ) , the present study showed no significant benefit for patients who underwent a total hip arthroplasty through a minimally invasive Watson-Jones approach in comparison with those who were managed with a st and ard transgluteal approach Purpose . To compare outcome after  total hip arthroplasty ( THA )  through the mini-incision approach versus the st and ard transgluteal approach . Methods . 80 women and 63 men aged 33 to 89 ( mean , 62 ) years with primary osteoarthritis of the hip were r and omised to undergo unilateral THA through a mini-incision approach ( Micro-hip , n=55 ) or st and ard , lateral , transgluteal approach  ( Bauer , n=88 ) . Levels of haemoglobin , haematocrit , serum creatine kinase , and C-reactive protein , length of hospital stay , mobilisation , and any complication were recorded . Visual analogue scale ( VAS ) for pain was assessed . Hip function was assessed using the Harris Hip Score and the Oxford Hip Score , whereas general health was assessed using the EQ-5D general health question naire . The cup inclination and varus/ valgus of the stem position were measured using a goniometer . Results . The Micro-hip group achieved a significantly lower mean incision length ( 9.3 vs. 13.4 cm , p<0.001 ) , mean surgical time ( 60 vs. 68 minutes , p=0.021 ) , mean reduction in haemoglobin level ( 2.1 vs. 2.8 g/dl , p<0.001 ) , and mean VAS for pain from hour 6 to day 6 ( all p<0.05 ) . One patient in the Micro-hip group developed early aseptic loosening of the cup and underwent revision surgery at month 4 . Three patients in the Bauer group and one patient in the Micro-hip group sustained intra-operative non-displaced fractures of the proximal femur , which were fixed with cerclages . Two patients in the Micro-hip group developed deep vein thrombosis during week 1 . Conclusion . THA through the Micro-hip approach achieved faster pain relief The advantages of minimally invasive surgical approaches for total hip arthroplasty are reported to include reduced blood loss , less pain , and shorter hospital stays , which combine to afford a faster recovery1 - 4 . However , other studies have failed to show any significant advantage over the use of st and ard surgical approaches ( Fig. 1)5 - 8 . Reported disadvantages of minimally invasive techniques are the substantial learning curve required and an increased risk of early complications3,9 - 12 . In addition , the long-term outcomes of minimally invasive procedures in terms of implant fixation and longevity remain unproven . Fig. 1 The st and ard direct lateral approach to the hip previously described by Frndak et al.21 is performed with the patient in the lateral decubitus position . ( Printed with permission of Joint Implant Surgeons , Inc. ) There are three basic categories of so-called minimally invasive total hip arthroplasty approaches : an abbreviated incision ( small incision ) , modifications of st and ard approaches with smaller incisions and less soft-tissue dissection ( less invasive ) , and novel approaches that reportedly do not cut muscle ( minimally invasive ) . We have had a broad experience , over the past seven years , with a less invasive modification of the direct lateral approach ( a modified Hardinge approach ) ( Fig. 2 ) . We previously reported less blood loss and a shorter hospital stay in association with this approach13 . Others have argued that the less invasive direct lateral approach does not provide an advantage over the traditional approach5 . Importantly , the soft-tissue dissection still requires removing and repairing the abductor musculature . Fig. 2 The less invasive direct lateral approach is performed with the patient in the lateral decubitus position . This approach employs an abbreviated skin and fascial incision with a limited abductor muscle dissection13 . ( Printed with permission of Joint Implant Surgeons , Inc. ) Several recent reports have BACKGROUND AIMS Evaluation of : 1 . early clinical and radiographic results of  total hip arthroplasty ( THA ) through a st and ard lateral direct approach , 2 . early clinical and radiographic results of THA through a minimal lateral approach , 3 . comparison of the results of THA in these two groups . MATERIAL AND METHODS 120 THAs ( 60 cementless and 60 cemented ) done in 120 patients due to degenerative changes were evaluated prospect ively . 60 THAs were done through a minimal lateral approach and constituted a study group . 60 THAs were done through a direct lateral approach and constituted a control group . The mean age of the 120 patients ( 98 women and 22 men ) was 45 y.o . ( range : 32 - 67 y.o . ) . The duration of follow-up in the study group was from 6 to 12 months ( mean : 8.5 months ) . The duration of follow-up in the control group was from 10 to 16 months ( mean : 10.5 months ) . Mean preoperative functional status of the study group was 44.5 points according to the Harris hip score . Radiographic evaluation of the results was done according to the criteria of the Joint Committee of the Hip Society , AAOS and SICOT . RESULTS 6 months after THA , clinical results were 92 pts in the study group and 88 pts in the control group . Radiographic outcomes were very good in all 120 patients from both arms : there were no differences between the control and study group . The incidence of complications was similar in both groups . CONCLUSIONS Minimally invasive THA demonstrated its value in the treatment of  degenerative changes of the hip joint  with regard to short-term outcomes . The clinical and radiographic outcomes were comparable between the st and ard and minimally invasive approaches . Success with THA using a minimally invasive approach depends on excellent operative technique and experience with st and ard hip approaches rather than on the use of special instruments In this prospect i ve study we compared clinical and radiological results and rehabilitation progress of 64 patients who underwent total hip arthroplasty using the st and ard lateral approach with 64 patients operated with a minimal-invasive ( MIS ) posterior approach .  The outcome of our study did not show any significant differences with regard to patient 's safety such as complication rate and radiological assessment of the cup position . There was no difference in the duration of surgery , blood loss , hospital stay and postoperative leg length discrepancy . Rehabilitation milestones were achieved earlier by MIS patients and three and six months postoperatively , the Harris Hip Score of the MIS group was significantly higher Minimally invasive total hip arthroplasty  using a short skin incision is a subject of much debate in the literature . The present study estimates the possible minimal length of the exposure in an unselected patient cohort and compares the lateral mini-incision technique and traditional total hip arthroplasty ( THA ) .  One hundred and two patients were divided into three groups according to the type of surgery and length of incision : mini-incision ( less than 10  cm ) was performed in 38 patients ; midi-incision ( 10–14 cm ) in 43 ; and  st and ard-incision ( longer than 14 cm ) in 21 patients . No statistical difference was found with regard to intraoperative and total blood loss , the rate of complications , and postoperative recovery . Significantly decreased body mass index ( BMI ) , shorter operative time , and higher number of hips with malpositioning of the acetabular cup were found in the mini-incision group . These patients , however , experienced less pain in the early postoperative period and were highly satisfied with the cosmetic results . The length of incision was shortened and optimized ( less than 14 cm ) in 82 % of patients , and mini-incision was performed in 38 patients of this unselected cohort . Because of the underst and able dem and of the patients for less invasive intervention , the surgeon should use a smaller but not necessarily mini-incision with minimal soft tissue trauma that still allows him to perform the procedure well , without compromising the type of implants and the otherwise excellent long-term results . R and omized prospect i ve studies are needed to explore the real value of the minimally invasive total hip arthroplasty . RésuméLa chirurgie arthroplastie de la hanche par voie mini invasive est un sujet de débat et de controverse dans la littérature . Cette étude a pour but d’estimer la longueur minimale de la voie d’abord sur une suite de patients non sélectionnés et de comparer la technique de mini incision avec la technique d’incision traditionnelle antérolatérale .  Cent deux patients ont été divisés en trois groupes , en fonction du type de chirurgie et en fonction de la longueur d’incision . Premier groupe : mini incision moins de 10 cm chez 38 patients , deuxième groupe : incision moyenne 10 à 14 cm chez 43 patients et troisième groupe : incision st and ard , supérieure à 14 cm chez 21 patients . Aucune différence statistique n’a été trouvée pour la perte sanguine et sur le taux des complications post-opératoires . Dans le groupe des mini incisions peu de sujets avaient une surcharge pondérale , par contre , il existait un gr and nombre de hanches avec une mal position de la cupule . Ces patients ont cependant présenté moins de douleur dans la période post-opératoire et ont été très satisfaits du résultat cosmétique . La longueur de l’incision dans la chirurgie prothétique de la hanche peut être raccourcie et la longueur optimum peut être de moins de 14 cm chez 82 % des patients . Une mini incision a été réalisé dans cette série , chez 38 patients du fait de la dem and e des patients pour une chirurgie mini invasive , les chirurgiens ont utilisé une petite incision avec un minimum de traumatisme des tissus mous . Cette mini incision doit donc permettre au chirurgien de réaliser son intervention correctement sans compromission sur le type d ’ implants , ni sur la qualité des résultats à long terme . Il n’y a pas besoin pour cela nécessairement d’une mini incision néanmoins des études prospect ives r and omisées doivent être réalisées pour explorer le vrai résultat de la chirurgie arthroplastie par voie mini invasive A group of 42 primary total hip arthroplasties performed through an abridged surgical incision ( group 1 ) was prospect ively compared to a cohort of 42 primary total hip arthroplasties performed through a st and ard surgical incision ( group 2 ) . The length of the incision was 8.8 + /- 1.5 cm for group 1 and 23.0 + /- 2.1 cm for group 2 . The groups were not significantly different with respect to age , height , preoperative Harris Hip scores ( HHS ) , estimated blood loss , or length of hospital stay ( P>.05 ) . Group 1 patients had a lower body mass index than group 2 patients ( P<.01 ) . Length of surgery was slightly less for group I ( P = .02 ) . A 0 % incidence was found of infection , nerve palsy , component malposition , and aseptic loosening in both groups . No dislocations occurred in group 1 , and one dislocation occurred in group 2 . Patients in group 1 have expressed considerable enthusiasm regarding the cosmetic appearance of the surgical incisions , and their postoperative HHS are slightly higher than those of group 2 ( P = .042 ) . Total hip arthroplasty can be performed safely and effectively through an abridged surgical incision , but this investigation confirms no dramatic clinical benefit other than cosmetic appeal Scar cosmesis is one of the proposed benefits of mini-incision total hip replacement as opposed to st and ard-incision procedures ; however , there has been no scientific proof of this clinical outcome . The cosmetic appearances of healed incisions of 34 primary total hip replacement procedures done by one surgeon using either a mini-incision ( 20 procedures ) or a st and ard-length incision ( 14 procedures ) were compared at an average of 2 years postoperatively . Each scar ’s appearance was grade d independently by two plastic surgeons using a st and ardized rating system . Patients answered a question naire regarding their subjective assessment of their scar . The blinded observers found that more mini-scars ( six of 20 ) were rated poor than st and ard scars ( one of 14 ) and that more st and ard-incision patients had scars that were rated good . More mini-incision patients ( two of 20 versus zero of 14 ) had wound-healing problems . All the patients thought that their hip scar was acceptable in appearance , but 30 of 31 patients rated the relief of pain and total hip replacement longevity as higher priorities than scar cosmesis . The cosmesis of mini-incision total hip replacement scars may be inferior to st and ard-incision scars because of skin and soft tissue damage produced by high retractor pressures needed for exposure using a limited skin incision . Level of Evidence : Therapeutic study , Level II-2 ( prospect i ve comparative study ) . See the Guidelines for Authors for a complete description of levels of evidence The mini-posterior approach for total hip arthroplasty ( THA )  belongs to the mini-incision approaches . In comparison to st and ard approaches , less muscle trauma result ing in less pain , less blood loss and faster rehabilitation in the early postoperative period are attributed to this approach , as known for all other minimally invasive approaches . In a prospect i ve study of 100 cases of THA it could be shown that this is true when comparing the mini-posterior approach with the posterolateral approach . Lower levels of muscle enzymes as a parameter for muscle trauma , could not be seen BACKGROUND Minimally invasive total hip arthroplasty has stirred substantial controversy with regard to whether it provides superior outcomes compared with total hip arthroplasty performed through longer incisions . The orthopaedic literature is deficient in well- design ed scientific studies to support the clinical superiority of this approach . The objective of this study was to compare the results of a single mini-incision approach with those of a st and ard-incision total hip arthroplasty in the early postoperative period . METHODS Two hundred and nineteen patients ( 219 hips ) admitted for unilateral total hip arthroplasty between December 2003 and June 2004 were r and omized to undergo surgery through a short incision of < or=10 cm or a st and ard incision of 16 cm .  All patients were blinded to the size of the incision for the duration of the hospital stay . The anesthetic , analgesic , and postoperative physiotherapy protocol s were st and ardized , with the staff also blinded to the technique used . A single surgeon , who had performed more than 300 short-incision hip replacements prior to the start of this study and who performs an average of 415 primary total hip replacements a year , performed all procedures through a single-incision posterior approach using a cementless cup and cemented stem . RESULTS The two groups were matched for age , grade according to the system of the American Society of Anesthesiologists , and body mass index . No significant difference was detected with respect to postoperative hematocrit , blood transfusion requirements , pain scores , or analgesic use . We found no difference in early walking ability or length of hospital stay and no difference in component placement , cement-mantle quality , or functional outcome scores at six weeks . The patient variables significantly associated with a probability of early discharge independent of incision length were patient age and preoperative hemoglobin levels ( p < 0.05 ) . The surgical scars contracted significantly over six weeks ( p < 0.05 ) but by a similar proportion of 11 % to 12 % in both groups . CONCLUSIONS Minimally invasive total hip arthroplasty performed through a single-incision posterior approach by a high-volume hip surgeon with extensive experience in less invasive approaches to the hip is safe and reproducible . However , it offers no significant benefit in the early postoperative period compared with a st and ard incision of 16 cm . As it is not known whether lower-volume and less-experienced surgeons can achieve similar results , the mini-incision technique merits further study before wide dissemination and implementation of this family of surgical approaches can be recommended
Operative time and blood loss were significantly reduced in the mini-incision group for studies with the posterior or posterolateral approach .
Concerning postoperative complications , there were no significant differences between the two groups with no significant heterogeneity .
No differences were observed between the two groups for Harris hip score and radiographic results except for cup anterversion .
Although mini-incision appeared to have similar outcomes compared to st and ard incision , the follow-up is short-term according to current st and ards in THA .
Le temps opératoire et les pertes sanguines étaient significativement moins importants dans le groupe mini-incision réalisé par voie postérieure ou postéro-latérale .
Il n'y a pas de différence significative dans les complications postopératoires entre les deux groupes de même en ce qui concerne le score de Harris , les résultats radiologiques exceptés pour l'antéversion de la cupule .
The purpose of this study was to compare the operative outcome between mini and st and ard incisions in total hip arthroplasty ( THA ) .
High- quality studies are required to compare the outcomes of these two procedures .ResuméLe but de cette étude est de comparer le devenir opératoire des patients ayant bénéficié d'une prothèse totale de hanche par voie  mini-invasive ou par incision st and ard .
