Small cell osteosarcoma of a toe phalanx: a case report and review of literature

This report describes the radiological and histological findings of a small cell osteosarcoma of a toe phalanx in a 38 year old man. This man presented with pain, swelling and redness of the left third toe. Medical history revealed an osteomyelitis of this toe eight years prior. Based on clinical findings and medical history the lesion was diagnosed as an osteomyelitis. However, peroperatively the lesion had a malignant aspect. Histological examination revealed a small cell osteosarcoma of the proximal phalanx

An impinging remnant meniscus causing early polyethylene failure in total knee arthroplasty: a case report

The management of patients with an apparently normal functional total knee arthroplasty (TKA) suffering from unexplained persistent pain and swelling is a challenging issue. The usual causes of pain after total knee replacement are well known, but there are a small number of patients in whom its aetiology is obscure. Malfunction due to soft tissue impingement has rarely been reported. A patient with an unusual case of posterior soft tissue impingement secondary to a trapped posterior horn of a remnant medial meniscus after TKA and responsible for severe early polyethylene wear, is reported. The diagnosis was confirmed by arthroscopy. Treatment was performed by arthrotomy. The meniscus remnant was removed followed by total synovectomy and isolated exchange of the polyethylene insert. To our knowledge, this is the first well-documented case reporting this association

Occlusion of the common femoral artery by cement after total hip arthroplasty: a case report

The incidence of vascular injuries after total hip arthroplasty is extremely low. In this report we describe an unusual injury to the common femoral artery. A 59-year-old Caucasian woman presented with rest pain, numbness and cramps in the operated limb after hip replacement. Cement leakage under the transverse ligament had caused occlusion of the common femoral artery necessitating vascular reconstruction. She had a good functional recovery at follow-up. To the best of our knowledge, this is the first well-documented case reporting this pathomechanism of vascular lesion to the femoral artery. This case report highlights the potential risk of such a limb-threatening complication, and awareness should lead to prevention by meticulous surgical technique (correct technique of pressurization) or to early detection of the lesio

Bilateral massive osteolysis of uncertain origin after total knee arthroplasty: A case report and review of literature

Introduction and importance: Periprosthetic osteolysis (PPOL) is a common complication after total knee arthroplasty (TKA) and is most commonly caused by wear-induced particles. Case presentation: We report an unusual case of massive bilateral PPOL in the posterior flanges of the femur and patellae 4 years after bilateral uncemented TKA without patellar resurfacing in a 71-year old female. Bilateral staged revision surgery including polyethylene exchange and allograft morselized bone impaction was performed to treat the osteolytic lesions. There were no signs of implant malalignment, polyethylene wear or component loosening. Clinical discussion: Several factors are associated with an increased risk on PPOL (e.g. polyethylene sterilization method, patient age, male gender). Surgical intervention in the context of massive PPOL should include replacement of a potential particle generator (most often polyethylene), correction of potential malalignment, treatment of bone defects and assessment of implant anchorage. Conclusion: This report highlights the available evidence on clinical presentation, associated risk factors and preferred treatment strategy of massive osteolytic lesions after TKA according to available evidence

Results and Patient Reported Outcome Measures (PROMs) after One-Stage Revision for Periprosthetic Joint Infection of the Hip: A Single-centre Retrospective Study

Background: Little is known about functional outcome and quality of life (QoL) after one-stage revision for periprosthetic joint infection (PJI) of the hip. Methods: a cohort of 30 subjects treated with one-stage revision between 2011 and 2015 was identified, and questionnaires on functional outcome and QoL were distributed. Results: 28 subjects were successfully treated (93%). Most subjects were referred from other hospitals. Coagulase-negative Staphylococcus was found in 50% of the cases, and 40% of all cultured bacteria were multidrug-resistant. 25% had subsequent revision surgery, unrelated to PJI. Functional outcome was good and QoL scores were high, comparable to prosthetic joint revision surgery in general. Conclusion: Although the cohort was small and statistical analysis was not performed, this study showed that excellent results can be obtained with one-stage revision for hip PJI. Functional outcome and QoL was comparable to prosthetic joint revision surgery in general

Arthroereisis of the subtalar joint: an uncommon complication and literature review

Arthroereisis is an operation to prevent abnormal pronation in the subtalar joint in children and adults with symptomatic flexible flatfeet. In the present report, we describe an uncommon late complication of a former variation of this procedure, namely the case of an adult male who experienced migration of a xenogeneic bone graft that had been implanted 55 years earlier. A thorough review of the existing data was also undertaken to better understand the complications of this procedure. (C) 2012 by the American College of Foot and Ankle Surgeons. All rights reserve
