Orthopedics Surgery Science

This depends strongly on fracture stability, fixation quality, soft tissues, bone quality and syndesmotic fixation. Typical components include: * Elevation and swelling control * Splint initially * Early ankle/toe motion when appropriate * Progressive physiotherapy * Protected or partial weight bearing initially for many unstable fractures * Gradual progression toward full weight bearing based on healing and fixation There is no single universal weight-bearing timeline. For example, AO describes early light partial weight bearing in some anatomically reconstructed stable fractures, whereas more unstable injuries or those with certain syndesmotic constructs require greater protection. 7. Important complications Early * Wound problems * Infection * Skin necrosis, particularly with severe swelling * Neurovascular injury * Loss of reduction * Implant failure * DVT Late * Post-traumatic ankle arthritis * Chronic pain/stiffness * Syndesmotic malreduction * Nonunion or delayed union * Hardware irritation * Need for implant removal 8. High-yield surgical principles For exams and surgical learning, remember: “Reduce the fibula → restore the mortise → fix the malleoli → test/reduce the syndesmosis → confirm fluoroscopically.” The most important technical principle is anatomic reduction, particularly restoration of fibular length/rotation and the relationship of the talus to the tibia and fibula. If you’re studying this for orthopedic surgery, I can also give you a detailed step-by-step ORIF of bimalleolar/trimalleolar ankle fractures, including patient positioning, approaches, reduction maneuvers, screw sizes/directions, syndesmotic tests, and postoperative protocol.

Absolutely. Ankle fracture fixation generally means restoring the ankle mortise and stabilizing the fractured malleoli with screws, plates, wires, or other implants. The most common operative technique is ORIF (open reduction and internal fixation). 1. When does an ankle fracture need fixation? The key question is stability and joint congruity, not simply whether the bone is fractured. Fixation is commonly considered for: * Displaced or unstable bimalleolar fractures * Trimalleolar fractures * Displaced medial or lateral malleolar fractures * Fractures associated with syndesmotic disruption * Fracture-dislocations * Significant articular incongruity * Some posterior malleolar fractures, particularly when the fragment contributes substantially to instability or articular incongruity The objective is to restore fibular length, alignment and rotation, reduce the talus accurately within the mortise, and restore the syndesmosis when disrupted. 2. Basic anatomy The ankle mortise consists of: * Medial malleolus — distal tibia * Lateral malleolus — distal fibula * Posterior malleolus — posterior distal tibia * Talus * Syndesmosis — anterior inferior tibiofibular ligament, posterior inferior tibiofibular ligament, interosseous ligament/membrane A small change in fibular length or rotation can significantly affect talar position, so accurate reduction is very important. AO’s operative references describe a simple lateral malleolar fracture being treated with a lag screw and neutralization plate, while medial malleolar fractures are commonly fixed with lag screws. 3-Fracture Typical fixation Lateral malleolus, simple oblique Lag screw + neutralization plate Lateral malleolus, comminuted Bridging/locking plate Medial malleolus Usually 2 lag screws Small medial fragment K-wires + cerclage/compression wiring Posterior malleolus Lag screws or posterior buttress/plate fixation depending on morphology Syndesmotic disruption Syndesmotic screw(s) or suture-button-type fixation depending on injury and surgeon preference 4. Typical ORIF sequence The exact sequence depends on the fracture pattern, but a common approach is: A. Preoperative planning * AP, mortise and lateral radiographs * CT particularly for complex/posterior malleolar fractures * Assess soft-tissue swelling * Determine fracture classification and syndesmotic stability B. Reduction * Restore the fibula to its correct length * Correct translation and rotation * Restore the ankle mortise C. Fibular fixation For a simple oblique fracture: 1. Reduction 2. Lag screw across the fracture 3. Neutralization plate For comminution, a bridging plate may be preferable. D. Medial malleolus Usually: * Anatomical reduction * One or two lag screws perpendicular to the fracture plane If the fragment is too small or bone quality is poor, K-wires plus cerclage/compression wiring can be used. E. Posterior malleolus The decision depends heavily on CT morphology rather than fragment size alone. Larger or mechanically important posterior fragments may require direct fixation. A posterolateral approach can sometimes provide access to both the posterior fragment and fibula. F. Syndesmosis After fixation, the syndesmosis should be assessed. If unstable, it is reduced and stabilized, traditionally with a syndesmotic positioning screw, although flexible fixation systems are also widely used. The fibula must be accurately reduced within the incisura before syndesmotic fixation; malrotation or malposition can lead to persistent ankle dysfunction. 5. Intraoperative assessment Fluoroscopy is used to check: * AP view * Mortise view * Lateral view * Fibular length and rotation * Talar reduction * Syndesmotic alignment * Screw length and position * Absence of intra-articular screw penetration AO specifically emphasizes confirming reduction and ensuring screws do not enter the ankle joint, using multiple fluoroscopic planes. 6.

Preparing for Knee Replacement: Tests, Home Setup & Checklist -  Preparing for knee replacement surgery involves more than showing up at the hospital. This guide covers the essential medical tests you need, how to set up your home for a safe recovery, and a complete checklist to follow before your procedure. By covering these steps in advance, you reduce stress and improve your outcome. Understanding the Pre-Surgery Medical Tests Your surgeon will order several tests to confirm you are ready for the operation. These tests check your heart, lungs, blood, and overall health. Completing them early helps avoid last-minute delays. Common Tests Before Surgery Blood work: A complete blood count checks […] Read More: https://orthofixar.com/for-patient/preparing-for-knee-replacement-tests-home-setup-checklist/
