Ten patients with chronic dorsal fracture subluxation of the distal interphalangeal joint were managed over 5 years with volar plate advancement arthroplasty. The mean time from injury to definitive surgical treatment was 8 weeks (range, 2 weeks to 4 months). All injuries were characterized by volar comminution and impaction of the distal phalanx, with associated dorsal subluxation. Surgical treatment included volar plate advancement arthroplasty and K-wire fixation of the reduced joint for 4 weeks. All patients were evaluated at an average postoperative duration of 25 months (range, 10-60 months). The average arc of motion of the distal interphalangeal joint of the 4 fingers (6) was 42 degrees and of the interphalangeal joint of the thumb (4) was 51 degrees. All patients had a residual flexion contracture averaging 12 degrees (range, 6 degrees to 25 degrees ). Volar plate advancement arthroplasty is an effective treatment for chronic distal interphalangeal joint dorsal fracture subluxation

Forty patients with Galeazzi fracture-dislocations were treated with open reduction and internal fixation of the radial shaft fracture. Intraoperative distal radioulnar joint (DRUJ) instability after anatomic reduction was managed with supplemental wire transfixion of the DRUJ (10 patients) or open reduction and triangular fibrocartilage complex repair (3 patients). Two patterns of fracture-dislocation were identified based on the location of the radial shaft fracture. Twenty-two type I fractures were in the distal third of the radius within 7.5 cm of the midarticular surface of the distal radius; 12 of these cases were associated with intraoperative DRUJ instability. Eighteen type II fractures were in the middle third of the radial shaft more than 7.5 cm from the midarticular surface of the distal radius. Only one of these fractures had intraoperative DRUJ instability after open reduction and internal fixation of the radial shaft fracture. A high index of suspicion, early recognition, and acute treatment of DRUJ instability will avoid chronic problems in this complex injury

Finger amputations are devastating, life-changing injuries. They can occur from many different types of injury, but most often are caused by power tools or machinery in the workplace. Modern microvascular surgical techniques have enabled surgeons to successfully reattach fingers that have been amputated at almost level of injury. Patient outcome and digit viability have improved as surgeons have gained more experience with microvascular techniques, and have narrowed the operative indications for replantation. Currently, replantation is recommended for amputated thumbs, multiple digit amputations, and single digit amputations distal to the FDS insertion, as well as all amputations in children. Replantation surgery is technically demanding. Success relies on patient selection, meticulous operative technique, and postoperative monitoring. Most patients have successful outcomes with at least protective sensation and useful range of motion in the replanted digit. Though complications, including joint stiffness, tendon adhesions, malunion, and cold intolerance are not infrequent, patient satisfaction following replantation is high.

The one-bone forearm procedure can be a successful salvage option for forearm stability in selected patients and is indicated if instability and bone loss are irreparable by other means. We report a case of a dysfunctional arm secondary to radical debridement of the ulna after osteomyelitis treated successfully with a one-bone forearm procedure and followed up for 8 years

Distal radius fractures commonly are sustained by athletes during competition. Typically, these are high energy injuries with severe displacement, metaphyseal comminution, and articular surface disruption. Each fracture is distinguished by its degree of articular displacement, stability, and reducibility. Management is contingent on recognition of the variable magnitude of articular disruption and skillful treatment based on specific fracture configuration

Controversy persists regarding optimal management of perilunate injuries. Traditionally, closed treatment, with or without percutaneous pin fixation, was advocated for these highly unstable carpal disruptions, but the inconsistent and often disappointing outcome of closed reduction, coupled with the recognition that functional recovery closely parallels the accuracy of restoring carpal alignment, have led to increasing enthusiasm for open treatment. The favorable outcome reported in this article supports both the contention that the acute perilunate injury affords the opportune time for operative preservation of carpal stability and the efficacy of the combined dorsal and volar approaches as the optimal means of surgical repair. This clinical experience also corroborates experimental evidence that perilunate injuries are apt to cause a predictable spectrum of osseous and soft tissue lesions--lesions usually suitable for early, precise repair. For the skilled athlete, prompt recognition and precision treatment of all components of injury are the critical factors to attain a functional outcome commensurate with a successful return to competition

Congenital anomalies of the thumb are rare and challenging conditions. There are many possible ways of addressing these various disorders, with potential to improve the function and appearance of the hand.

Rotatory subluxation of the scaphoid remains a challenging problem; a thorough understanding of the basic anatomy, particularly the ligament complexes of the wrist, as well as wrist kinematics are required for the proper diagnosis and treatment. Our understanding of rotatory subluxation of the scaphoid has improved over the years and continues to expand.

Twelve patients with chronic stage III or stage IV perilunate dislocations were managed over the past 7 years by proximal row carpectomy. All dislocations were untreated or incompletely reduced for a minimum of 8 weeks after injury. The mean time from injury to definitive treatment was 15 weeks (range, 8 weeks to 6 months). Surgical management was inclusive of a dual dorsal and volar approach. Median nerve decompression, lunate excision, and capsuloligament repair was performed volarly and scaphoid and triquetrum carpectomy was accomplished dorsally. Temporary radio capitate K-wire fixation during early soft tissue healing was uniformly performed. All patients were evaluated at an average postoperative duration of 40 months (range, 28 months to 7 years). Marked relief of wrist pain and median nerve dysesthesias was routinely achieved. Effective wrist range of motion and grip strength were restored. Untreated stage III and IV chronic perilunate dislocation treated by proximal row carpectomy eliminates pain and restores function to a severely injured wrist
