Objective To investigate the effectiveness of suspensory external fixation technique in treatment of proximal humeral fractures.Methods Between August 2013 and October 2018, 14 patients with proximal humeral fractures were treated with suspensory external fixation technique. There were 10 males and 4 females with an average age of 55.9 years (range, 43-76 years). There were 10 cases of falling injury and 4 cases of traffic accident injury. Among them, there were 9 cases of Neer type Ⅲ and 5 cases of Neer type Ⅳ. The time from injury to operation was 3-7 days (mean, 4.6 days). Nine cases were complicated with osteoporosis. The preoperative visual analogue scale (VAS) score was 6.1±1.2. The effectiveness was comprehensively evaluated by hospital stay, fracture healing time, removal time of external fixator, postoperative complications, VAS score, and Neer score of shoulder joint function.Results All operations were successfully completed, and the hospital stay was 6-14 days, with an average of 9.4 days. All the incisions healed by first intention, and no infection or other complications occurred. All patients were followed up 16-60 months (mean, 35.4 months). X-ray films examination showed that all fractures healed, the healing time was 4-7 months (mean, 4.9 months). The removal time of external fixator was 5-8 months (mean, 6.3 months). VAS scores were 1.5±0.8 at 1 month after operation and 1.0±0.9 at last follow-up, both of which were significantly improved when compared with preoperative score, the differences were significant between different time points (P<0.05). Neer score of shoulder joint function was 75-100 (mean, 91.1); 9 cases were excellent, 4 cases were good, and 1 case was fair. The excellent and good rate was 92.9%. During follow-up, there was no adverse events such as acromion impingement, nonunion, or pseudoarthrosis.Conclusion For proximal humeral fractures, the suspensory external fixation technique is a simple and reliable treatment method that can significantly improve joint function.
