Repair of Acute Grade-3 Combined Posterolateral Corner Avulsion Injuries Using a Transosseous Krackow Suture Pull-Through Technique.

Background: For complete disruption of the posterolateral corner (PLC) structures, operative treatment is most commonly advocated, as nonoperative treatment has higher rates of persistent lateral laxity and posttraumatic arthritis. Some studies have shown that acute direct repair results in revision rates upwards of 37% to 40% compared with 6% to 9% for initial reconstruction. In a recent study assessing the outcomes of acute repair of PLC avulsion injuries with 2 to 7 years of follow-up, patients with adequate tissue were shown to have a much lower failure rate than previously documented.

Orthopaedic Manifestations of Scurvy in an Otherwise Healthy Child from a Low Opportunity Index Neighborhood: A Case Report.
JBJS Case Connect
January 2024
Department of Orthopaedic Surgery, Montefiore Einstein, Bronx, New York.
Case: A 23-month-old otherwise healthy female child from a low opportunity index neighborhood presented with 1 month of lower extremity pain and refusal to bear weight. Radiographic evaluation of bilateral knees revealed lucent metaphyseal bands and a nondisplaced distal femoral metaphyseal corner fracture. A workup identified vitamin C deficiency (scurvy), and the child's symptoms and radiographic abnormalities resolved with vitamin C supplementation.

JBJS Essent Surg Tech
May 2023
Musculoskeletal Oncology Unit, Mount Sinai Hospital, University of Toronto, Toronto, Ontario, Canada.
Background: The Reconstructive Allograft Preparation by Toronto Sarcoma (RAPTORS) protocol is reliable and reproducible without substantially adding to the surgical reconstruction time or cost. Our technique includes clearance of debris, lavage of the medullary canal, pressurized filling of the medullary canal with antibiotic-laden cement for its mechanical and antimicrobial properties, and insertion of cancellous autograft at the allograft-host junctional ends prior to dual-plate compression to fix the allograft into the defect. Our experience with large intercalary allograft reconstruction has demonstrated high rates of long-term success and addresses the most common causes of large allograft failure (infection, fracture, and nonunion), as shown in our long-term outcome study.

Chondroblastoma is a rare benign cartilaginous tumor mostly confined to the epiphyses and apophyses. Cases outside the epiphyseal region are exceedingly rare. Extramedullary chondroblastomas are exceptional; to our knowledge, only two cases qualified as "periosteal chondroblastoma" have been described in the literature.
