Anatomical snuff box People with<unk> s generally have snuffbox tenderness. Focal tenderness is usually present in one of three places: 1) volar prominence at the distal wrist for distal pole fractures; 2) anatomic snuff box for waist or midbody fractures; 3) distal to Lister's tubercle for proximal pole fractures. Complications<unk>  pseudarthrosis, before and after treatment with Herbert screw. Vascular supply of the<unk>  comes from two different vascular pedicles. 20-30% of the blood supply (a.) comes from the volar branch of the radial artery and enters the bone at the tubercle. 70-80% comes from (b.) the dorsal branch of the radial artery and travels towards the proximal pole. Avascular necrosis (AVN) is one complication of<unk> . Since the<unk>  receives its arterial supply in a retrograde fashion (i.e. from distal to proximal pole), the part proximal to the fracture is usually affected. Risk of AVN depends on the location of the fracture. * Fractures in the proximal third have a high incidence of AVN (~30%) * Waist fractures in the middle third is the most frequent fracture site and has moderate risk of AVN. * Fractures in the distal third are rarely complicated by AVN. Non union can also occur from undiagnosed or undertreated<unk> s. Arterial flow to the<unk>  enters via the distal pole and travels to the proximal pole. This blood supply is tenuous, increasing the risk of nonunion, particularly with fractures at the wrist and proximal end. If not treated correctly non-union of the<unk>  can lead to wrist osteoarthritis. Symptoms may include aching in the wrist, decreased range of motion of the wrist, and pain during activities such as lifting or gripping. If x-ray results show arthritis due to an old break, the treatment plan will first focus on treating the arthritis through anti-inflammatory medications and wearing a splint when an individual feels pain in the wrist. If these treatments do not help the symptoms of arthritis, steroid injections to the wrist may help alleviate pain. Should these treatments not work, surgery may be required.
