Abstract:
Objective To summarize the methods of operative treatment for complex proximal humeral fractures and its clinical results. Methods 40 cases with complex proximal humeral fractures underwent operation from December 1999 to February 2002. Of 40 cases, 29 were followed up with a mean of 25 months (11 to 40 months). Using Neer system, Constant-Murley rating system and questionnaire were adopted to classify the fractures and evaluated postoperative functions of the daily life and work. A deltoid-pectoral approach was used in all patients. The surgical neck fractures were fixed with the terminal threaded pin or modified Ender's nail. The tubercle fragments were sutured with non-absorbable Ethibond No.5 or "8" figure tension band wire. Results The average absolute Constant-Murley score was 81.7(54 to 96), the excellent and good rate was 65%(19/29), fair 24%(7/29), and poor 11%(3/29). The average forward elevation was 142.5?(60? to 180?). The average pain VAH score was 12(9 to 15). The humeral head avascular necrosis, detected by the follow-up X-ray film, was diagnosed if the humeral head was completely or partially absorbed or reduced. In three-part fractures, 71% cases were excellent or good results, no poor result, and 17% had humeral head necrosis; in four-part fractures, 58% cases were excellent or good results, 25% poor, and 67% were found with humeral head necrosis. The extent of the humeral head necrosis was one of main causes to the poor function for complex proximal humeral fractures. All of the fractures healed at 6 to 8 weeks postoperatively without delayed union and nonunion. Conclusion For complex proximal humeral fractures, a good clinical result can be obtained on condition of the anatomical reduction of the tubercle fragments, as well as the stable fixation of the surgical neck fracture with appropriate suture materials and proper post-operative rehabilitation. Satisfactory result is possible even while the humeral head avascular necrosis happened.
