Normal passive range of motion of the first metatarsal joint is 70Â° of extension and 45Â° of felxion. Hallux rigidus describes a first metatarsophalangeal joint with restricted range of motion. Range of motion restriction is usually a result of osteophyte accumilation in an arthritic joint.
A range of 24Â° to 30Â°combined motion (dorsiflexion and plantar flexion) isneeded for normal walking, 37Â° is needed for ascendingstairs, and 55Â° is needed for descending stairs. 4,5 There are numerous reports on ankle arthroplasty in theliterature.1â3,6,7 Few mention the preoperative and/or post-operative ROM.,3 Dorsiflexion was 2.1Â° (range, â2Â°â10Â°). Themean ankle plantar flexion was 16.4Â° (range, 0.0Â°â34.0Â°),with a combined true tibiotalar ROM of 18.5Â° (range,3.0Â°â44.0Â°) (Table 1).At 1-year followup, there was a limited, but significant(p 0.0037), improvement in the tibiotalar ROM (Table Fig 1AâC.
