Phalangeal neck fractures in adults

The author investigated the pattern of injury and outcome of management in 11 adults with phalangeal neck fractures. The mean age was 40 years. The fracture occurred at the neck of the proximal phalanx of the thumb in seven cases and at the neck of the middle phalanx of the fingers in the remaining four cases. One patient had an undisplaced (Type I) fracture and was treated with splinting; the final result was graded as excellent. Nine patients had Type II fractures (the displaced distal fragment maintaining bone-to-bone contact with the proximal fragment) and all patients were treated with closed reduction and single K-wire fixation. The final outcome of Type II fractures was considered good in eight patients and fair in one patient. One patient had a Type III fracture (the displaced distal fragment was rotated 180 degrees with no bone-to-bone contact with the proximal fragment). The fracture required open reduction and K-wire fixation and the final result was poor.
