[Experiences with the OrTra-prosthesis in primary prosthetic replacement of fractures of the humeral head--indication, technique and results].
Displaced three - and four - part fractures of the humeral head are at high risk for a poor functional outcome after internal fixation. Primary prosthetic replacement can restore the pretraumatic anatomy and early mobilisation is possible. Functional outcome after hemiarthroplasty of the shoulder joint after trauma however is poor, regardless the type of implant used. However, a stable, painless joint is obtained at a "one time surgery". In our institute from April 1996 until January 2001 fifty-eight primary OrTra-prostheses were implanted. In 43 patients we could perform the follow up. The patients revealed a mean range of active movement from about flex./ext. 54 degrees/0/40 with abd./add. 67 degrees/0/20 degrees. Most important for the patients was the achieved painfree shoulder in 86% (ASES index) of all cases.
