Ligaments of Pelvis
Inherent stability of the pelvis is provided by ligaments. The 3 groups of ligaments are: 1. Sacrum to Pelvis: Sacroiliac ligamentous complex: is divided into posterior (short and long) and anterior ligaments. Posterior ligaments provide most of the stability. Sacrotuberous ligament: runs from the posterolateral aspect of the sacrum and the…

Oestern and Tscherne Classification for Closed fractures
The classification system for closed fractures is based on the physiologic concept that the energy imparted to the bone (and the resultant fracture pattern) directly correlates with the energy transferred to the surrounding soft tissues. Grade Soft tissue injury Fracture Compartment C0 Absent or Negligible Simple (Spiral) Soft and/or Normal…

Screw-home mechanism
Synonym: Knee-locking mechanism Definition: During the final degrees of knee extension (last 20-30 degrees), an obligatory lateral rotation of the tibia occurs, i.e. non-voluntary coupled movement of knee extension and external rotation. Mechanism: External rotation of tibia with reference to the femur or Internal rotation of femur with reference to…
