Surgeon perspectives on a virtual reality platform for preoperative planning in complex bone sarcomas.

Background And Objectives: Treatment of primary bone and soft tissue sarcomas typically includes complete surgical resection with or without adjunctive modalities. Despite best efforts, for the most challenging clinical scenarios such as axial or pelvic sarcoma, five-year survival rates are reported to be between 27 and 40 %. Since quality of resection is a key determinant of oncologic outcomes, it is critical to preoperatively plan the surgical approach to improve resection accuracy, ensure sufficient surgical margins, and reduce the risk of local or metastatic recurrence.

Treatment of Unicameral Bone Cysts Utilizing the Sclerograft™ Technique.

Purpose: To evaluate the Sclerograft™ procedure, which is an image-guided, minimally invasive approach of chemical sclerotherapy followed by bone grafting of unicameral bone cysts (UBC).

Materials And Methods: A retrospective evaluation from August 2018 through August 2023 was performed at a single institution on patients that underwent the Sclerograft™ procedure for UBCs. Radiographic healing was evaluated utilizing the Modified Neer Classification.

Clear cell chondrosarcoma: a review of clinicopathologic characteristics, differential diagnoses, and patient management.

Clear cell chondrosarcoma (CCC), an extremely rare primary bone tumor, is currently classified by the World Health Organization as a low-grade malignant cartilaginous neoplasm. Clinically, CCC occurs primarily in males with a peak incidence in the third to fifth decades of life, and occasionally, it presents in skeletally immature patients. Unlike conventional chondrosarcoma, CCC has a predilection for the epiphysis of long bones and often displays radiologic features reminiscent of chondroblastoma.

Immediate Plastic Surgery Intervention after Soft Tissue Sarcoma Resection: Examining Wound Healing, Readmission, and Reoperation.

Unlabelled: Many orthopedic and surgical oncologists use a multidisciplinary approach to soft tissue sarcoma (STS) resection. This study assesses the role of immediate plastic surgeon involvement during index soft tissue sarcoma resection.

Methods: Adult patients who underwent index STS resection between 2005 and 2018 were queried from an institutional database.

Vascularized Medial Femoral Condyle Periosteal Flaps With Allograft Bone for Distal Radius Giant Cell Tumors: A Case Report.

Case: Distal radius reconstruction after giant cell tumor (GCT) resection is typically performed with free fibular flaps when a vascularized bone is needed. However, vascularized fibular flaps are contraindicated in patients with peroneal artery variants. We present 2 patients with GCTs of the radius and bilateral peronea arteria magna who underwent resection with wrist fusion using an allograft bone and vascularized free medial femoral condyle periosteal flaps.

Cognitive Apprenticeship in Orthopaedic Surgery: Updating a Classic Educational Model.

Objective: To define cognitive apprenticeship and describe how it can be applied to orthopedic education.

Design: Traditional apprenticeships have been used through history as a teaching model for wide variety of skills. These apprenticeships are characterized by practical, on-the-job training in which the apprentice observes and assists a master in the completion of a task, and thereby learns the skills needed to complete that task on his or her own.

Cognitive Skills Assessment for the Aging Orthopaedic Surgeon: AOA Critical Issues.

Physician leaders are increasingly confronted with the challenge of evaluating the performance of surgical colleagues during the last phase of their careers. Identification of physicians with declining cognitive and clinical skills must be balanced against awareness of laws protecting colleagues from discrimination. Responding successfully to this challenge requires appropriate policies, reliable data, standardized evaluation tools, consistent documentation, and the development of compassionate and effective solutions that avoid discriminatory practices.

Valgus Osteotomy with Plate-and-Nail Fixation for the Treatment of Proximal Femoral Deformities Due to Fibrous Dysplasia: A Report of Two Cases.

Case: We describe 2 cases of proximal femoral deformity due to fibrous dysplasia that were corrected with osteotomies and a novel combined construct with a blade plate and a retrograde intramedullary nail.

Conclusion: A single-stage procedure using a combined construct with a blade plate and a retrograde intramedullary nail is a viable option for correcting and subsequently preventing proximal femoral deformities due to fibrous dysplasia.

Tenosynovial Giant Cell Tumor in the Midfoot Treated With Femoral Head Allograft Reconstruction.

Tenosynovial giant cell tumor (also known as giant cell tumor of tendon sheath or pigmented villonodular synovitis) is a rare soft tissue tumor that arises from the tenosynovium of a tendon sheath or the synovium of a diarthrodial joint. This disease process occurs infrequently in the foot and ankle but can result in significant bone erosion and destructive changes of affected joints. These cases are challenging to treat, because the tumor most commonly presents in young, active patients and can be associated with extensive bone loss.

Can We Agree on Expectations and Assessments of Graduating Residents?: 2016 AOA Critical Issues Symposium.

Orthopaedic educators are responsible for training a prepared and competent workforce that will provide effective care for a growing number of patients with musculoskeletal conditions. Currently, there are both internal and external forces that pose substantial challenges to medical students, residents, program directors, faculty members, and chairs in achieving this goal. One area of particular concern is the education of surgeons, whose knowledge and professional behavior must be matched by their ability to acquire procedural skills.

Novel intramedullary device for lengthening transfemoral residual limbs.

Background: Lower limb loss is a highly disabling medical condition that can severely impact a person's quality of life. Recovery becomes especially challenging if an amputee has a short residual limb, which can complicate proper prosthetic fitting, causing discomfort, difficulties in suspension, and reduced mobility. Current limb lengthening techniques such as the Ilizarov apparatus and external fixators are cumbersome, uncomfortable, and have high complication rates.

Thromboembolic Disease in Patients with Metastatic Femoral Lesions: A Comparison Between Prophylactic Fixation and Fracture Fixation.

Background: We are not aware of any previous studies that have compared the rate of venous thromboembolic events in patients who underwent prophylactic intramedullary nailing because of an impending fracture with the rate in patients who underwent intramedullary nailing after a pathological fracture. The objective of the present study was to determine if the rate of venous thromboembolic events varies between patients who are managed with prophylactic fixation and those who are managed with fixation after a pathological fracture.

Methods: We performed a retrospective comparative study in which the Nationwide Inpatient Sample database was used to identify all patients who had undergone femoral stabilization, either for a pathological femoral fracture or for prophylactic fixation of femoral metastatic lesion, over a period of 10 consecutive years (between 2002 and 2011) in the United States.

The Core Competencies for General Orthopaedic Surgeons.

Background: With the changing delivery of orthopaedic surgical care, there is a need to define the knowledge and competencies that are expected of an orthopaedist providing general and/or acute orthopaedic care. This article provides a proposal for the knowledge and competencies needed for an orthopaedist to practice general and/or acute care orthopaedic surgery.

Methods: Using the modified Delphi method, the General Orthopaedic Competency Task Force consisting of stakeholders associated with general orthopaedic practice has proposed the core knowledge and competencies that should be maintained by orthopaedists who practice emergency and general orthopaedic surgery.

Update on Antibiotic Prophylaxis for Genitourinary Procedures in Patients with Artificial Joint Replacement and Artificial Heart Valves.

Infection of artificial joint replacements and heart valves is an uncommon but serious complication encountered anytime after the implantation of these prostheses. It is known that bacteremia can lead to infection of a prosthetic device. However, there is no strong evidence to correlate urologic procedures with the development of periprosthetic joint infection or prosthetic valve endocarditis.
