Of 46 patients, 30 with fresh fractures of the humerus, nine with non-unions and seven with pathological fractures were treated with a new locked intramedullary nail. Of 30 patients with a fresh humeral fracture, three were lost to follow-up. All fresh fractures healed within 4 months. Functional results of the fresh fracture group were excellent in eighteen patients and satisfactory in three patients. Two patients with Neer type 6 fractures had unsatisfactory shoulder function; in the four other patients poor shoulder function resulted from a pre-existing condition. Out of nine non-unions, six united within 6 months. The three other patients with atrophic non-union required bone-grafting later, after which consolidation was obtained. The long functional recovery period of the non-union group was related to the pre-existing limited shoulder function. The seven patients with a pathological fracture died within 8 months of operation. While alive they were free from pain and could be nursed well.
46例患者中，30例为肱骨新鲜骨折，9例为骨不连，7例为病理性骨折，均采用新型带锁髓内钉治疗。30例肱骨新鲜骨折患者中，3例失访。所有新鲜骨折均在4个月内愈合。新鲜骨折组18例患者功能结果优秀，3例患者功能结果满意。2例Neer 6型骨折患者肩部功能不满意；另外4例患者肩部功能不佳是由既往疾病导致。9例骨不连患者中，6例在6个月内愈合。另外3例萎缩性骨不连患者后来需要植骨，之后获得了骨愈合。骨不连组功能恢复时间长与既往存在的肩部功能受限有关。7例病理性骨折患者在术后8个月内死亡。在存活期间，他们没有疼痛，护理情况良好。
