Objective: To study distraction hinged motion arthroplasty of the ankle joint in combined treatment of osteoarthritis in terminal stages.
Material And Methods: Ankle distraction hinged motion arthroplasty in the Ilizarov frame was performed in 10 patients with terminal post-traumatic osteoarthritis (mean age 54±6.2 years). Surgical technique and design of the Ilizarov frame, as well as additional reconstructive interventions are described.
Results: Preoperative VAS score of pain syndrome was 7±2.3 cm, after 2 postoperative weeks - 1±0.5 cm, 4 weeks - 0.5±0.5 cm, 9 weeks or before dismantling - 0±0.5 cm. Arthroscopic debridement of anterior part of the ankle joint was carried out in 6 cases, posterior part - 1 case, anchor reconstruction of lateral ligamentous complex (InternalBrace technique) - 1 case, anchor reconstruction of medial ligamentous complex - 2 cases. Restoration of anterior portion of syndesmosis was performed in 1 case. Pin site infections occurred in 2 cases. In one case, there was a breakdown of the wire fixator holding the pin passed through the talus in 5 weeks after surgery.
Conclusion: Preliminary results allow us to characterize the proposed design of the Ilizarov frame layout and surgical technique as relatively simple and promising for postponing radical surgery on the ankle joint.

Introduction: Hinge knee joint prosthesis are utilized in a variety of surgical scenarios, including complex primary, revision, salvage surgeries, and radical resection of tumor's. Link's Endo-model Hinged Knee Prosthesis is a newer design that includes ramped tibial components for controlled pivot point motion during flexion and an anti-dislocation feature to prevent prosthesis dislocation..

However, lateral hinge fractures (LHFs) pose a significant complication. This study investigates protective measures to mitigate these fractures, guided by prior observations of mechanical stress impact on LHFs.

Background: Not all surgical osteotomy steps have been properly investigated for their potential impact on surgical accuracy. The main study objective was to investigate the osteotomy parameters that have respectively major and minor impact on coronal and sagittal bony accuracy in medial opening-wedge high tibial osteotomy (MOWHTO).
Methods: Three tibias from an existing 3D MOWHTO osteotomy database were chronologically selected based on segmentation quality, tibial plateau size and the presence of tibial varus.
Introduction: Medial open wedge high tibial osteotomy is a biological procedure for treating unicompartmental knee osteoarthritis. The literature repeatedly highlights the significance of preserving an intact lateral hinge during this procedure. We investigated the temporal course of distraction forces during distraction at the osteotomy site, aiming to quantitatively measure and analyse temporal changes in distraction forces at different distraction points for intact and fractured lateral hinges.

Article Synopsis
- The study aimed to assess how lateral hinge fracture (LHF) impacts the early success of supramalleolar osteotomy (SMO) in treating varus-type ankle osteoarthritis and identify associated risk factors.
- A total of 39 patients were analyzed, revealing that 13 developed LHF post-surgery while 26 did not, but both groups had similar osteotomy healing times.
- Significant differences in pain levels and functional scores were found between the two groups at the last follow-up, indicating that LHF may influence outcomes after SMO.
