Abstract:
Indication for this hemi-wedge high tibial osteotomy is the combination of medial osteoarthritis or cartilage damage, varus deformity of >10°, and medial proximal tibial angle of <80°. The proximal lateral tibia is exposed via a skin incision of approximately 10 cm length between the tibial tuberosity and the head of the fibula. After detachment of the anterior tibial muscle, a first oblique guidewire marks the main osteotomy plane and a second guidewire marks the hemi-wedge. Then, the osteotomy is performed along the guidewires with an oscillating saw and the laterally based wedge is removed. After percutaneous needling of the medial collateral ligament with a cannula, the lateral gap is closed and stabilized with an angular-stable plate. The rehabilitation protocol includes partial weight-bearing with 10 kg for 6 weeks and free range of motion.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
