Biomechanical consequences of Zadek osteotomy in insertional achilles tendinopathy: A virtual surgical simulation study.

Background: The Zadek osteotomy modified by Taylor (ZO) is a surgical technique used to treat insertional Achilles tendinopathy (IAT) by reducing the heel's prominence and elevating the Achilles tendon insertion. This study aims to analyze the biomechanical consequences of IAT after ZO using a virtual surgical simulation with a specific software.

Methods: A retrospective analysis of 20 wtbearing computed tomography (WBCT) scans of IAT patients was conducted.

Management of Painful Shoulder Arthroplasty: A Narrative Review.

Despite the recent advances in surgical techniques, the percentage of painful shoulder arthroplasties is still high (more than 10%). The causes of residual pain after shoulder arthroplasty, and the resulting treatment solutions, are many and different. The most common complications of shoulder prosthesis are infections, aseptic loosening, modular components disassembling, metal hypersensitivity, and instability.
