Treatment of a Radiation-Associated Femur Fracture with an Intercalary Endoprosthesis: A Case Report.

Case: A 72-year-old woman with undifferentiated pleomorphic sarcoma of the thigh received neoadjuvant chemotherapy and radiotherapy. She underwent wide resection and was scheduled for prophylactic fixation of the femur. However, prophylactic fixation was deferred secondary to COVID-19 pandemic.

Catastrophic Vascular Injury After Total Knee Arthroplasty.

Vascular injury is a feared complication of any surgical procedure. This study examined the incidence of vascular injury during total knee arthroplasty (TKA), the circumstances and timing of injury intraoperatively, and acute management. Eighteen cases of catastrophic vascular injury after primary TKA (12 of 19,577; 0.

COVID-19 and elective joint arthroplasty: Patient perspectives and considerations.

This study gauged patient perspectives regarding elective joint arthroplasty during the COVID-19 pandemic. Eligible patients undergoing consultation for primary hip or knee arthroplasty received a survey with questions regarding opinions towards COVID-19 and on undergoing elective procedures during the pandemic. Of the 112 respondents, 78% believed that their condition warranted surgery despite COVID-19 circumstances.

Comparison of all-polyethylene and metal-backed modular tibial components in endoprosthetic reconstruction of the distal femur.

Introduction: All-polyethylene (AP) tibial components have demonstrated equivalent or improved long-term survivorship and reduced cost compared with metal-backed (MB) components in primary total knee arthroplasty; however, there is a lack of data comparing these outcomes in the setting of an oncologic endoprosthetic reconstruction.

Methods: A total of 115 (88 AP:27 MB) patients undergoing cemented distal femur endoprosthetic reconstruction following oncologic resection were reviewed. Mean age was 40 years and 51% were females.

Utility of Bone Scintigraphy and PET-CT in the Surgical Staging of Skeletal Chondrosarcoma.

Background/aim: Surgical staging is paramount to treatment of primary bone sarcomas. Often, bone scintigraphy and/or positron emission tomography-computed tomography (PET-CT) are used to exclude skeletal metastases; however, skeletal metastases in chondrosarcoma are rare. The purpose of this study was to assess the utility of these staging methods in patients with chondrosarcoma.

Outcomes of knee arthroplasty for primary treatment of pathologic peri-articular fractures of the distal femur and proximal tibia.

Background: Treatment goals for pathologic fractures about the knee include pain relief and unrestricted weight bearing. In cases of condylar destruction, these fractures may not be amenable to internal fixation, and arthroplasty may be considered. The purpose of this study was to analyze the outcomes of knee arthroplasty for primary treatment of impending or pathologic fractures of the distal femur or proximal tibia.

Outcomes of Endoprosthetic Replacement for Salvage of Failed Fixation of Malignant Pathologic Proximal Femur Fractures.

Background: Internal fixation is often used to treat pathologic proximal femur fractures. However, nonunion and/or tumor progression may lead to hardware failure. In such cases, endoprosthetic replacement may be considered.

Modern Surgical Treatment of Recurrent Posterior Dislocation of the Native Hip.

Background: Redislocation of the native hip is rare. An anterior fulcrum between the proximal part of the femur and the pelvis must be present for a posterior dislocation to occur. The purpose of this study is to describe the cases of 9 patients with posterior redislocation or recurrent subluxation of the native hip that was treated with hip preservation surgery.

Horizontal Cleavage Meniscus Tear Treated With All-inside Circumferential Compression Stitches.

Horizontal cleavage meniscus tears are a common orthopedic injury often treated with partial or total meniscectomy versus repair. This Technical Note presents a technique for all-inside repair with uniform compression of the superior and inferior leaflets by placement of multiple circumferential compression stitches using an all-inside self-retrieving suture passing device. The currently described technique provides several advantages for all-inside repair of a horizontal cleavage tear: (1) eliminates the need for a posterior incision, (2) minimizes the risk of neurovascular injury, (3) uses standard arthroscopy portals (or small modifications), and (4) requires only a single suture deployment with a self-retrieving device for each circumferential compression stitch.

Patellar Tendon Repair With Ipsilateral Semitendinosus Autograft Augmentation.

Patellar tendon ruptures are rare but potentially devastating injuries. Acute repair after patellar tendon rupture affords the best opportunity for tension-free restoration of the extensor mechanism. Biological augmentation of primary repair is believed to decrease strain across the repair site and reduce the risk of rerupture.

Ipsilateral femoral head osteochondral transfers for osteochondral defects of the femoral head.

Osteochondral defects of the femoral head are rare. Several treatment options have been described, though there is currently no consensus on the appropriate management of these lesions. Five patients underwent femoral head osteochondral autograft transfer for treatment of ipsilateral femoral head osteochondral defects via surgical hip dislocation between 2011 and 2014 at our institution.

Satisfactory Results of the Exeter Revision Femoral Stem Used for Primary Total Hip Arthroplasty.

Background: The Exeter cemented femoral stem has demonstrated excellent clinical and radiographic outcomes as well as long-term survivorship free from aseptic loosening. A shorter revision stem (125 mm) with a 44 offset became available for the purpose of cement-in-cement revision situations. In certain cases, this shorter revision stem may be used for various primary total hip arthroplasties (THAs) where the standard length stem would require distally reaming the femoral canal.

Surgical Treatment of Pediatric Upper Limb Spasticity: The Shoulder.

The shoulder joint is essential for placing the hand in a functional position for reach and overhead activities. This depends on the delicate balance between abductor/adductor and internal/external rotator muscles. Spasticity alters this equilibrium, limiting the interaction of the upper limb with the environment.
