Sural n

Lateral ligaments of the foot are weaker than medial ligaments of foot. Most commonly injured lateral ligament of the foot?

Anterior talofibular ligament Due to inversion and internals rotation of the foot combined with ankle plantar flexion resulting in forward displacement of talus. Order of frequency of ligament tear anterior talofibular > calcaneofibular > posterior talofibular

Sprain 1st degree, 2nd degree and 3rd degree

1st degree sprain: partial or complete tear of anterior talofibular ligament. 2nd degree sprain: both anterior talofibular and calcaneofibular ligament are partially or completely torn. 3rd degree sprain: all 3 are partially or completely torn- anterior talofibular, calcaneofibular and posterior talofibular ligament,

Anterior hip dislocation vs Posterior hip dislocation

Anterior hip dislocation: Obturator L2-4 ``` Posterior hip dislocation: Superior Gluteal (L4-S1) or Inferior Gluteal (L5-S2) ```

Pelvic injury injures nerve?

Femoral nerve (L2-4)

Knee trauma

Tibial nerve (L4-S3) Source: sciatic nerve (L4-S3) , posterior thigh splits in common peroneal and tibial nerves .

Trauma or compression of lateral aspect of leg Or Fibula neck fracture

Common peroneal (L4-S2)
