Assessing Pain and Functional Outcomes of Percutaneous Stabilization of Metastatic Pelvic Lesions via Photodynamic Nails: A Bi-Institutional Investigation of Orthopaedic Outcomes.

Background: Minimally invasive surgical interventions for metastatic invasion of the pelvis have become more prevalent and varied. Our group hypothesized that the use of percutaneous photodynamic nails (PDNs) would result in decreased pain, improved functional outcomes and level of ambulation, and decreased use of opioid pain medication.

Methods: We performed a retrospective chart review of patients with metastatic pelvic bone disease undergoing stabilization with PDNs (IlluminOss Medical) at 2 institutions.

Bisphosphonate-loaded Bone Cement as a Local Adjuvant Therapy for Giant Cell Tumor of Bone: A 1 to 12-Year Follow-up Study.

Background: Historically, nontargeted adjuvant therapies such as liquid nitrogen, phenol, argon beam, and alcohol have been applied locally after curettage of giant cell tumors (GCT) in the extremities. Systemic bisphosphonates (BP) and denosumab have emerged as osteoclast-targeting therapies because osteoclast-like giant cells, responsible for aggressive bone resorption, are susceptible to BP or denosumab. However, such drugs may cause systemic side effects.

Evaluating the Duration of Prophylactic Post-Operative Antibiotic Agents after Open Reduction Internal Fixation for Closed Fractures.

Background: The importance of timely pre-operative antibiotic agents for effective surgical prophylaxis has been established but the optimal duration of antimicrobial coverage post-operatively has not yet been defined clearly. The purpose of this study was to determine if prophylactic post- operative cefazolin for 23 hours decreases the risk of surgical site infection (SSI) after open reduction internal fixation (ORIF) of closed extremity fractures.

Patients And Methods: After Institutional Reviews Board approval, patients undergoing ORIF of closed extremity fractures who had a planned post-operative stay of at least 23 hours were randomly assigned to either receive 23 hours of cefazolin or a placebo.

Surveillance Strategies for Sarcoma: Results of a Survey of Members of the Musculoskeletal Tumor Society.

Background. Surveillance is crucial to oncology, yet there is scant evidence to guide strategies. Purpose.

A novel treatment for bone lesions of multifocal epithelioid sarcoma-like hemangioendothelioma.

Epithelioid sarcoma-like hemangioendothelioma (ES-H) is a rare, indolent vascular neoplasm with characteristics similar to epithelioid sarcoma. It typically affects young males who present with skin and subcutaneous lesions in the extremities. Bone lesions, occurring in approximately 20% of patients, are often multifocal, seen in conjunction with soft tissue lesions, and usually found in bones of the lower extremities.

Rare case of dual lesion: nonossifying fibroma and osteochondroma.

In this paper, we offer radiographic and pathologic evidence of a unique coexisting dual lesion. A 14-year-old boy presented for evaluation of a painful right knee after sustaining a twisting injury. The patient was found to have a torn anterior cruciate ligament, in addition to incidental finding of distal femoral dual lesion composed of tissue consistent with a nonossifying fibroma and an osteochondroma.

Deceptively benign low-grade fibromyxoid sarcoma: array-comparative genomic hybridization decodes the diagnosis.

Low-grade fibromyxoid sarcoma (previously known as Evans tumor) is a rare soft tissue neoplasm characterized by a deceptively bland appearance despite the potential for late metastasis or recurrence. We describe a 13-year-old patient with a popliteal fossa mass initially thought to be benign that, because of array-comparative genomic hybridization findings and subsequent immunohistochemistry, was diagnosed as low-grade fibromyxoid sarcoma. The array-comparative genomic hybridization demonstrated a loss of 11p11.

Allograft compared with autograft infection rates in primary anterior cruciate ligament reconstruction.

Background: Injuries to the anterior cruciate ligament are the most common surgically treated knee ligament injury. There is no consensus regarding the optimal graft choice between allograft and autograft tissue. Postoperative septic arthritis is an uncommon complication after anterior cruciate ligament reconstruction.

Primary TKA with a zirconia ceramic femoral component.

This article presents the 2-year clinical results of primary total knee arthroplasty (TKA) performed with a zirconia ceramic femoral component. A posterior-stabilized TKA was performed for degenerative arthritis in 36 patients (39 knees). The components included a zirconia femoral component, a cobalt-chrome alloy tibial baseplate, and a polyethylene patella; all were implanted with bone cement.
