Description
ObJective Ulnar shortening to unload the ulnocarpal ligamentous complex. Indications Clinically relevant ulnar impaction syndrome, be it congenital or posttraumatic. Contraindications Concomitant pronounced malunion of the radius. Osteoarthritis of the distal radioulnarjoint. Surgical Technique Ulnopalmar approach. Oblique osteotomy of the ulna in its distal third. Removal of a bony wafer of predetermined thickness. Internal fixation with a 7-hole LD-DC plate or special plate and lag screw. Results 29 patients (14 men, 15 women, average age 42 years) underwent an ulnar shortening osteotomy for a therapyresistant ulnar impaction syndrome. Follow-up after an average of 25 (7-37) months. Average amount of shortening 4.5 (1.5-13) ram. 72% reduction of pain as determined with a visual analog scale. The range of motion was improved by 7% in extension/flexion, by 8% in abduction/adduction, and by 11% in pronation/supination. Grip strength measured with a vigorimeter (balloon size 5) increased by 12%. Complications: three malunions, effectively treated by revision of internal fixation.
