Talus Fractures: Evaluation and Treatment.

Talus Fractures: Evaluation and Treatment. J Am Acad Orthop Surg. 2020 Oct 15;28(20):e878-e887 Authors: Lee C, Brodke D, Perdue PW, Patel T Abstract The talus is unique in having a tenuous vascular supply and 57% of its surface covered by articular cartilage. Fractures of the head, neck, or body regions have the potential to compromise nearby joints and impair vascular inflow, necessitating surgical treatment with stable internal fixation in many cases. The widely preferred approach for many talar neck and body fractures is a dual anterior incision technique to achieve an anatomic reduction, with the addition of a medial malleolar osteotomy as needed to visualize the posterior talar body. Percutaneous screw fixation has also demonstrated success in certain patterns. Despite this modern technique, osteonecrosis and osteoarthritis remain common complications. A variety of new treatments for these complications have been proposed, including vascularized autograft, talar replacement, total ankle arthroplasty, and improved salvage techniques, permitting some patients to return to a higher level of function than was previously possible. Despite these advances, functional outcomes remain poor in a subset of severely injured patients, making further research imperative. PMID: 33030854 [PubMed - as supplied by publisher]

Abstract OBJECTIVE: Provision of a natural scaffold, good quality cells, and growth factors in order to facilitate the replacement of the complete osteochondral unit with matching talar curvature for large medial primary and secondary osteochondral defects of the talus. INDICATIONS: Symptomatic primary and secondary medial osteochondral defects of the talus not responding to conservative treatment; anterior-posterior or medial-lateral diameter>10 mm on computed tomography (CT); closed distal tibial physis in young patients. CONTRAINDICATIONS: Tibiotalar osteoarthritis grade III; multiple o...

We present a review of the published data on the complications and treatments for failed talar allograft transplantation. A case report is presented on a young woman who experienced graft failure and osteonecrosis of her talar allograft transplant. Because of the size of the present osteonecrosis, an ankle arthrodesis was performed as the initial revision procedure. Talar necrosis was removed and revascularized from the ankle fusion with solid fusion was confirmed with computed tomography. Symptomatic adjacent joint pain quickly developed in the hindfoot after the ankle fusion, and 12 months later an ankle fusion conversio...

AbstractPurpose of ReviewTrauma is the principle cause of osteoarthritis in the ankle, which is associated with significant morbidity. This review highlights the current literature for the purpose of bringing the reader up-to-date on the management of posttraumatic ankle arthritis, describing treatment efficacy, indications, contraindications, and complications.Recent FindingsRecent studies on osteoarthritis have demonstrated variability among anatomic locations regarding the mechanisms and rates of development for posttraumatic osteoarthritis, which are attributed to newly discovered biological differences intrinsic to ea...

Authors: Muratori F, Totti F, D'Arienzo A, Scorianz M, Scoccianti G, Beltrami G, Campo FR, Citarelli C, Capanna R, Campanacci DA Abstract Due to advances in neoadjuvant therapies and preoperative imaging modalities, joint-sparing resections have become appealing in bone tumor surgery. However, the intercalary reconstruction of metadiaphyseal bone defects of the femur and the tibia after juxta-articular tumor resection remains challenging. Both biological and prosthetic reconstructions have been used for joint-sparing resections, but little is known about the long-term outcome of these procedures. The authors review...
