Background: Proximal pole scaphoid fracture nonunions are challenging conditions to treat. When significant comminution of the proximal pole and avascular necrosis is present, scaphoid proximal pole reconstructive options are considered. The proximal pole of the hamate is a local autograft option; however, little has been described on the outcomes of this procedure. Methods: Patients who underwent proximal pole scaphoid reconstruction using proximal hamate autograft at 3 tertiary care centers were retrospectively reviewed. Radiographic union was classified by greater than 50% bony trabeculae across the reconstruction site on computed tomography scan. Results: Ten patients were included. Average age at the time of surgery was 27.9 years, and 60% were men. Average length of proximal hamate autograft harvested was 10 mm. All patients healed at an average of 14.3 weeks following surgery. At final follow-up, 3 patients reported no pain, 3 reported mild occasional pain, 2 reported moderate tolerable pain (1 at the hamate graft site), and 2 had no reports on their pain level. Conclusions: In small proximal pole scaphoid nonunions with fragmentation and avascular necrosis, ipsilateral proximal hamate autograft reconstruction of the scaphoid proximal pole is a viable and reproducible option with high rates of union and patient satisfaction.

Background: An institutional review board–approved study of the functional outcomes of patients after surgical treatment of hamate arthrosis lunotriquetral ligament tear (HALT) lesions was conducted. Methods: In all, 21 wrists in 19 patients underwent arthroscopic, open, or combined treatment of HALT lesions. Seven patients underwent isolated hamate debridement and 14 had concomitant procedures to address lunotriquetral pathology. Nineteen wrists underwent procedures to address additional pathology, including triangular fibrocartilage complex, ulnotriquetral ligament split, and scapholunate ligament injuries. Results: Mayo wrist scores increased from 54 to 71. Sixteen patients had no or mild pain postoperatively, compared with none preoperatively. When stratified by lunotriquetral interosseous ligament management, 75% of the limited treatment group (none or debridement) and 78% of the additional treatment group reported improved pain. Three patients underwent additional surgeries for persistent pain. Conclusion: Resection of the proximal pole of the hamate can improve pain and function for patients with ulnar-sided wrist pain secondary to a HALT lesion. Concomitant wrist pathologies should be considered when determining treatment plans.
