    Abstract:
    OBJECTIVE: To study therapeutic effects of retrograde locked intramedullary nail for the treatment of middle or distal fractures of humeral shaft. METHODS: From October 2002 to February 2005, 21 patients with middle or distal fractures of humeral shaft were treated with AO retrograde locked intramedullary nail. Among the patients, 13 patients were male and 8 patients were female, ranging in age from 23 to 56 years, with an average of 34.5 years. Nineteen patients were fresh fractures, and 2 patients were old fractures. Eleven patients had middle fractures of humeral shaft, and other 10 patients had distal fractures of humeral shaft. Two patients with old fractures were non-union and treated with autoallergic bone grafting; 5 patients combined with radial nerve injury underwent exploration. The therapeutic effects were evaluated according to Constant-Murley shoulder score and Mayo elbow score. RESULTS: All the patients were followed up, ranging from 18 to 24 months, with an average of 20.8 months. The fractures were healed except 1 patient with old fracture and 1 patient with extremely distal acute fracture. The shoulders and elbows had satisfactory recovery except 1 patient with old fracture. The mean Constant-Murley score was (83.6 +/- 13.4) points (50-97), 12 patients got an excellent result, 5 good, 4 fair and no bad; the mean Mayo elbow score was (88.6 +/- 9.8) points (65-95), 13 patients got an excellent result, 5 good, 3 fair and no bad. CONCLUSION: The retrograde locked intramedullary nail offers an ideal treatment method for middle and distal fractures of humeral shaft. Strict operative indication, precise surgical techniques and stable locking are the keys to a successful treatment results.
