A 35-year-old male presented with pain and inability to bear weight in his left lower extremity 4 months after index left total hip arthroplasty. He underwent revision left total hip arthroplasty for a type III defect using an antiprotrusio ring and allograft. Patient was found to have a broken acetabular cup and a loose femoral stem. Early acetabular cup breakage of this severity has not been reported.  相似文献

To the editor:I congratulate the authors for conducting a meta-analysis of randomized controlled trials to investigate the efficacy and safety of the intravenous use of tranexamic acid (TA)in total knee arthroplasty (TKA).1 We do agree with them that TA effectively reduces blood loss and transfusion rate as well as transfusion volume after TKA and does not apparently increase the risk of deep vein thrombosis (DVT) or pulmonary embolism (PE).2  相似文献

Avascular necrosis of the femoral head is a known complication of femoral neck fracture but on the contrary,femoral neck fracture in a case of preexisting avascular necrosis is a very rare phenomenon.W...  相似文献

Anterior cruciate ligament (ACL) reconstruction is usually recommended for young patients. Several recent articles have however reported comparable outcomes of ACL reconstruction between youth and patients in fourth or fifth age group. But in the literature there are not many reports about ACL reconstruction in patients over 70 years old. We report a case of a successful arthroscopic ACL reconstruction (using single bundle quadrupled hamstring graft) in an active 75-year-old medical practitioner. Successful outcome after ACL reconstruction can be achieved in selected older patients; chronological age is no barrier.  相似文献

We report a rare case of periprosthetic posttraumatic fracture of subtrochanteric region of femur alter a megaprosthesis of the knee, done for resistant non- union of distal femur with secondary osteoarthrosis in a 51 years old man. Treatment with a locking femoral plate was able to achieve primary union with a good result.  相似文献

Objective:Fracture of either radius or ulna with a dislocation either at the proximal or distal radioulnar joint (DRUJ) is not a common injury and is inherently unstable.Here we report a case series,with both-bone forearm fractures associated with dislocation of DRUJ,as a Galeazzi-variant type fracture-dislocation,and try to analyze this injury pattern.Methods:The study was based on 6 patients having Galeazzi-variant type fracture-dislocation of different age (20 to 45 years).All fractures were closed type.Two fractures involved the same level and three fractures were at different levels of radius and ulna shaft.After thorough examination and investigations they were treated with limited contact dynamic compression plate without additional fixation for DRUJ.Results:All cases were followed up for 24 weeks.The maximum incidence occurred in age group between 31 and 40 years.All the fractures of both radius and ulna were united in average time of 12 weeks.Range of motion of wrist and elbow,supination and pronation at final follow-up were normal.There was no subsequent re-subluxation or dislocation of the DRUJ in any of the cases.Conclusion:Galeazzi variant in adult is a new undescribed pattern of forearm with wrist injury.Stable open reduction and internal fixation of both-bone forearm fractures is mandatory,followed by 3 to 4 weeks of immobilization in a cast for the healing of disrupted DRUJ.  相似文献
