Event Description

This report is being filed after the review of the following journal article: kahle, m., david, e.,filler, r.D., gressner, v.(1992), the dynamic condylar screw (dcs) in proximal femoral fractures.Initial experiences, unfallchirurgie, vol.18, pages 44-47 (germany) doi: 10.1007/bf02588239.The aim of our study was to examine the suitability of the dcs for the treatment of proximal femur fractures.Since january 1, 1987, a total of 19 patients (13 females and 6 males, aged 37 to 97 years, mean age 70 years) who had proximal femoral fractures were stabilized utilizing the "'dynamic condylar screw" (dcs).In the cases we applied the dcs hitherto employment of a bone distractor of complementary cancellous bone graft has been mandatory.An average of eight weeks after the procedure the patients were fully loaded.The following complications were reported as follows: a (b)(6) year-old male patient who had already had a lower-leg amputation as a result of arterial occlusive disease on the operated side presented himself with primarily good results and full load with prosthesis six months after the intervention with almost eliminated mobility in the left front joint.X-ray showed massive periarticular calcification with proper implant seat and bone consolidation of the fracture.Functionally, not least also as a result of a lack of cooperation on the part of the patient, this status could not be improved.2 patients complained of weather-dependent thigh pain.1 patient, 13 weeks after the first operation x-rays showed osteolysis in the area of the distal plate screw.We operated again, removed the 8-hole plate, and pushed a longer plate onto the screw that remained in the femoral collar.Subsequently, the tumor masses were cleared out, bone cement was inserted and the composite osteosynthesis ended after screwing this report is for an unknown synthes dynamic condylar screw (dcs).It captures the reported (b)(6) year-old male patient who had massive periarticular calcification and status could not be improved.This is report 1 of 4 for (b)(4).
