RESUMO

To investigate the possibility of resection arthroplasty of the sternoclavicular joint in treatment of dislocation of this joint.Methods:Five patients who had had resection arthroplasty of the sternoclavicular joint and in whom the costoclavicular ligament had to be reconstructed,follow-up averaged 1.8 years.Results:The average duration of follow-up were 1.8 years.All of the patients had an excellent result,no cases had infection、pain and abnormalities.Conclusion:We believe that resection arthroplasty of the sternoclavicular joint and preservation reconstruction of the costoclavicular joint is essential,and it is a satisfactory and safe way for the treatment of dislocation of the sternoclavicular joint.

RESUMO

Seven cases of benign bone tumors, a case of spinal fusion and. seven rases of un-united fractures of shafts of long bones, were treated with a.llogenir bone matrix gelatin (BMG) implants and were followed up for more than one year. All tumor cases were cured by osteo-induction from BMG, while only three of the seven fractures united. Two of the failures were reimplanted with BMG and failed again. Not a single case developed post-operative infection nor immunologic reaction. The BMG used was obtained from the same preparation, so that deterioration of its biological activity by endogenous protease was not likely. BMG small BMG cubes were used in tumor cases and slabs in fractures. The small cubes . were mixed with pieces of gel-foam and parked into the post-operative bony cavities while the slabs were arranged layer by layer at the fracture sites. This might be one of the reasons why the tumor rases had higher rate of cure Another reason was that non-unions needed prolonged, continuous and firm internal and external fixation post-operatively while the tumor cases needed not The amount of BMP calculated from BMG was not enough for early and solid osteogenesis. In the authors'opinion, with the use of new biomaterial, it should be followed by new method of application, but the principles of surgery should not be changed
