Unlabelled:
Treatment of complex fractures of the humeral head remains an obviously unsolved problem. Under consideration of the problems of head preserving methods, the development of the last years tended towards the hemiprosthetic replacement. As the discussion about the methods and implants continues to be controversial, long-term results of Neer-II-replacement of humeral head in own trauma cases are presented here.
Patients And Methods:
46 patients were investigated, in whom a cemented Neer II hemiprosthesis was implanted between 1983 and 1996 due to complex fracture patterns. Median age was 60.2 years, 74 % of patients were female. 59 % had a luxation fracture type Neer VI, 22 % presented a concomitant nerval lesion. Follow up was performed 5 years on average after the operation. 38 patients were investigated clinically according the score of Constant and Murley, 36 had a x- ray control. Additionally an individual questionnaire was completed by 46 patients.
Results:
Average Constant-score was 66.2 points, whereas in 76.3 % a satisfactory or better result was achieved. In 23.9 % the outcome was poor. In one patient (2.2 %) explantation of the hemiprosthesis and shoulder fusion due to pain was necessary. Conditions for a good result were a patient aged 50 years and younger (75.9 pts. versus 64.2 pts.), an early hemiprosthetic replacement within 4 weeks after the trauma (71.7 pts. versus 55.3 pts.) and a patient without an earlier operation and nerval lesion (76.8 pts. versus 53.9 pts.). No correlation was found between the date of the follow-up and the interval of time since the operation.
Conclusion:
After complex fractures of the humeral head satisfactory long-term results can be obtained by the cemented Neer II hemiprosthesis. Thus, implants of the newer generation can not yet whitness their superiority under consideration of functional aspects. Refixation and reintegration of both the tubercula after trauma still seems to be an unsolved problem and requires further development.
