Die Doppelplattenosteosynthese der proximalen Ulna

OBJECTIVE: Stable osteosynthesis during early postoperative functional treatment, particularly in patients with osteoporosis.

INDICATIONS: Metaphyseal fractures, small proximal fragments or avulsion fracture of the triceps tendon, osteotomy of the olecranon, and pseudarthrosis of the olecranon or proximal ulna.

CONTRAINDICATIONS: Skin infection, severe soft tissue lesions.

SURGICAL TECHNIQUE: Dorsal approach to the olecranon. Open reduction and internal fixation by two side-mounted angular locking compression (double) plates.

POSTOPERATIVE MANAGEMENT: Early functional treatment. Full load-bearing after 6-12 weeks postoperatively.

RESULTS: A total of 14 patients were treated with double-plate osteosynthesis between 2011 and 2012. Clinical data were analysed retrospectively. The average follow-up was 11.7 months (range, 4-21 months). The mean flexion-extension radius was 123° (100°-140°), the pro-supination radius 166° (160°-170°). Using the Mayo Elbow Performance Score, eight patients had excellent and six good results. The mean Quick-DASH score was 15 (0-50).
