RESUMEN
PURPOSE: To review 15 patients who were treated for intraneural ganglions of the hand and wrist. METHODS: Between 1990 and 2012, 15 patients were treated for intraneural ganglions of the hand and wrist. There were 9 women and 6 men, averaged age 42 years. Ten patients presented with a mass and 5 with symptoms of entrapment neuropathy. The ganglions involved the ulnar nerve at the wrist in 5 patients, the dorsal branch of the ulnar nerve in 2, the superficial radial nerve in 2, a digital nerve in 4, and the dorsal branch of a digital nerve in 2. Eight patients had magnetic resonance imaging evaluations that showed cystic masses that did not confirm intraneural ganglions. In all patients diagnosis was made intraoperatively. Ganglions were treated by intraneural dissection and excision of the cyst in 10 patients, excision of the articular branch and decompression of the cyst in 4, and excision of the ganglion and the nerve in 1. RESULTS: Postoperative follow-up averaged 57 months. There were no complications or recurrences. Five patients had transient paresthesias that improved after an average of 2 months. Preoperative symptoms improved in all patients. Patients returned to normal daily and work activities at an average of 10 days. CONCLUSIONS: Intraneural ganglions should be considered in the differential diagnosis of a mass in the vicinity of a nerve. Surgical excision is usually curative but simple excision of the articular branch and decompression of the cyst seems simpler and equally effective. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

PURPOSE: Perilunate injuries are complex and occasionally go unrecognized acutely. Open reduction and internal fixation is a valid treatment option for these injuries. The purpose of this study was to evaluate the functional outcome of treating chronic perilunate injuries with open reduction and internal fixation. METHODS: Between 1998 and 2007, we treated 24 patients for chronic perilunate injuries. We excluded 5 patients from this study because they underwent proximal row carpectomy or limited wrist arthrodesis. We treated the remaining 19 patients with open reduction and internal fixation. Mean time from injury to surgery was 29 weeks. All patients were men, with a mean age of 27 years. A total of 13 patients had fracture dislocations (group 1); of these, 11 were transscaphoid and 2 were transscaphoid transcapitate fracture dislocations. Six patients had perilunate dislocations (group 2). RESULTS: Postoperative follow-up averaged 58 months. All carpal fractures healed at an average of 18 weeks. At final evaluation, the average pain scores during rest, daily activities, and manual work on a 20-point visual analog scale were 0, 2, and 3, respectively, with no significant difference between groups. The active extension and flexion of the wrist averaged 39% and 52% of the uninjured side, respectively. Grip strength averaged 87% of the uninvolved extremity. According to the Mayo wrist scoring system, 58% of all patients (69% of group 1 and 33% of group 2) achieved good to excellent results. A total of 18 patients returned to their original work activities; 14 patients (74%) were very satisfied. No patients required secondary procedures. CONCLUSIONS: Despite late presentation, patients with chronic perilunate injuries can be treated with open reduction internal fixation, with satisfactory results. Patients with lesser arc injuries have less successful outcome. Patients with irreducible dislocations or major articular damage may require wrist salvage procedures.
