Background: Autologous grafting is widely used in orthopedic surgery because of its high osteogenic capacity, immunologic compatibility, for the absence of risk of disease transmission, and for not requiring a bone bank. The posterior-superior calcaneal tuberosity is an option for obtaining a cortical and cancellous structural bone. This study aims to describe the operative technique and complications observed at the donor site of the posterior-superior calcaneal tuberosity.

Methods: Patients who underwent graft harvesting from the posterior-superior calcaneal tuberosity were retrospectively evaluated by pain outcomes, imaging tests, and intra- and postoperative complications.

Results: Twenty patients with a median age of 69 years (range 48-77) and follow-up of 16 months (12-26) were assessed. Median postoperative pain at the donor site was 0 (0-6), with 2 patients reporting persistent local pain. No case of Achilles tendon rupture or intra- or postoperative calcaneal fracture were identified. One patient developed a superficial infection that was quickly resolved using oral antibiotic therapy.

Conclusion: The posterior-superior calcaneal tuberosity is an alternative source of autologous graft with low donor site morbidity.

Level Of Evidence: Level IV, case series.

Radiological findings of fibrocartilaginous coalition of the third tarsometatarsal joint: a retrospective cross-sectional study with computed tomography and magnetic resonance imaging.

Acta Radiol 2020 Nov 19;61(11):1541-1544. Epub 2020 Feb 19.

SEDI II - Eigier Diagnósticos, São Paulo - SP, Brazil.

Background: Fibrocartilaginous coalition of the third tarsometatarsal joint has been indicated as an extremely rare form of tarsal coalition in the radiological literature, and most articles concerned with tarsal coalition do not mention involvement of this joint. Only two reports written in the English language that approach this subject were found, an orthopedic report and an anthropological report.

Purpose: To evaluate the prevalence of this finding and discuss and illustrate the radiological characteristics of this coalition.

Material And Methods: A retrospective analysis of 614 computed tomography or magnetic resonance imaging scans of the ankle and/or foot, acquired at a health service within a period of three months, was performed to assess the prevalence of this coalition.

Results: Of the examinations characterized as valid for analysis for the purposes of the study, 17 cases compatible with fibrocartilaginous coalition of the third tarsometatarsal joint were found, thus indicating an involvement of approximately 2.97% of the examined feet.

Conclusion: Our radiological findings are typical, and the prevalence found in this study was statistically significant, being similar to that described in the anthropological report (3.2%-6.8%).
