– Anatomy: – arises from lumbrosacral plexus: L4, L5, S1, S2, S3; – nerve emerges from pelvis below piriformis & enters thigh between ischial tuberosity & greater trochanter; – in 10% of patients, the sciatic nerve is separated in greater sciatic foramen by all or part of the piriformis; – sciatic nerve is … Read more
– Discussion: – involves creating an oblique osteotomy of the distal fragment (valgus osteotomy) to obtain stability in unstable intertroch frx; – this osteotomy changes frx plane from verticle to near horizontal & creates contact between the medial and posterior cortex of proximal and distal fragments; … Read more
