[Metacarpal fractures: treatment indications and options. Results of a multicenter study].

This multicenter study analyzes data on metacarpal fractures in 1260 patients to determine optimal treatment concepts. Of the 740 patients followed up, 487 (66%) presented with fractures of a single metacarpal in one of the three most frequently observed locations (distal fractures of the 4th and 5th metacarpal, shaft fractures of the 2nd to 5th metacarpal, and fractures of the base of the first metacarpal). The overall clinical and radiological results were good to excellent. The "path" analysis used to identify baseline parameters and treatment options influencing outcome led to recommendations for metacarpal fracture treatment. Functional protocols are predominantly applied for postoperative/post-traumatic treatment. Pain and regional pain syndromes should be prevented whenever possible and early adequate treatment should be initiated due to their significant impact on outcome.
