Combination techniques, which encompass the combined use of vascularized bone grafts with massive allografts or autografts (recycled grafts), are especially important in biological reconstruction tumor-related lower extremity long defects. Liquid nitrogen recycled (frozen autograft) and free vascular fibula graft (FVFG) combination, was coined as "frozen hotdog (FH)" method by authors, has not been widely used nor its outcomes reported for significantly sized patient groups. This study aims...

Background: Little data exist regarding the adverse effects of Achilles tendon (AT) elongation after rupture repair on plantarflexion strength. This study aimed to investigate effect AT measured using resting angle (ATRA) strength in patients with surgically treated acute rupture. Methods: A retrospective chart review was performed 40 (15 female and 25 female) who underwent open operative due an At final follow-up, assessed ATRA. Plantarflexion (peak torques angle-specific torques)...
