Treatment of ulnar impaction syndrome with the wafer procedure.
Our objective was to evaluate the efficacy of wafer resection of the distal ulna (the wafer procedure) as treatment for ulnar impaction syndrome. Between 1995 and 1997, 26 patients were surgically treated for refractory wrist pain secondary to ulnar impaction syndrome. The diagnosis was based on physical examination, radiologic imaging, and wrist arthroscopy, and confirmatory pathoanatomy was identified at the time of surgery in all cases. The study population consisted of 18 women and 8 men, and patient age averaged 42 years. Follow-up averaged 27 months (range, 17-41 months). Twenty-three patients were completely satisfied with pain relief and the functional status of their wrists at final follow-up. Range of motion returned to baseline in the majority of cases, usually by 3 months, and grip strength increased an average of 11 kg (P < or = .005). The wafer procedure is an effective treatment alternative to ulnar-shortening osteotomy for ulnar impaction syndrome and avoids the risk of nonunion and hardware-related complications.
