Abstract
Introduction: In some special situations during the revision total hip arthroplasty with well fixed, well oriented acetabular cementless cup, orthopedic surgeons may prefer to retain the well-fixed cementless cup. The aim of this study was to report the follow-up of some cases treated with such a technique during a 10-year period.
Methods: During 2004-2014, all cases of revision total hip surgery performed in Sina Hospital, Tehran, Iran were evaluated. 14 of 82 cases (16.5%) had cemented polyethylene liner in cementless metal shell. The demographic data, reasons for use of such revision technique result was evaluated by Harris Hip Score.
Results: The most common reason was osteolysis (64%), and the most common cause was impaired locking mechanism (65%). There were few complications (one osteolysis and one infection). In five cases (36%) constrained liner was added and in 10 cases (72%) allograft was needed. The final Harris Hip Scores was good or excellent in 78%. Only one dislocation was seen.
Conclusion: Cemented cup in cementless shell can be used in revision hip arthroplasty in well-fixed Acetabular shell situations with acceptable outcom.

Background: Femoral neck non:::union::: could be a disaster in young and middle age patients. Conventional valgus osteotomy of femur is done without freshening of non:::union::: site. We would like to report our experience with valgus osteotomy of hip after freshening of the non:::union::: site.Methods: In a case-series study, from all young and middle-aged patients with non:::union::: femoral neck fracture who were treated with freshninig of non:::union::: site and valgus ostetomy, 22 patients (18 males, 4 females) with mean age of 34 (20-47) entered the study. There were 10 broken implants in the heads with a one year follow-up. The cases were evaluated for :::union:::, necrosis and also changes in Harris hip scores.Results: Preoperative Harris hip score was 63 and postoperative score increased to 89. The neck shaft angle was reached about 150 degrees. In 2 cases necrosis developed and in 3 cases collapse of neck occurred with intrusion of implant into the joint and the implants were removed immediately. Mean time to :::union::: was 4.5 months.Conclusion: Freshening of non:::union::: site before valgus osteotomy in non:::union::: femoral fracture produces high :::union::: rate with low complications.

Background: Unstable pelvic fracture means those fractures which are both vertically and rotationally unstable. The site of posterior instability could be in sacrum, posterior ilium, or sacro-iliac joint. The anterior injury may be in the symphysis pubis or pubic rami. Posterior fixation of pelvis with double rods inserted into the sacral alae of the ilium compressed together by knots is a stabilizing surgical option when iliosacral screw fixation is not feasible or available.Materials: Eleven patients with unstable pelvic fracture who had received posterior stabilization with two threaded rods and bolts in prone position after reduction of fracture with skeletal traction were studied retrospectively. The anterior fixation was either symphyseal plating or external fixator.Results: with a 6 months follow up, there was no evidence of device failure, infection, neurological deficit, or non-:::union:::. There was, however, some leg length discrepancy due to imperfect initial reduction.Conclusion: Posterior stabilization of pelvis by transiliac rods, in unstable pelvic fractures, is a simple procedure to be used effectively when more secure fixation is not available.
