Trochanteric bursae

Bursae trochantericae

Origin
Group of synovial bursae surrounding the greater trochanter: gluteus maximus trochanteric bursa (largest, between IT band/gluteus maximus and trochanter), gluteus medius, and minimus bursae
Insertion
Cover the lateral bony facets and tendinous insertions of the greater trochanter
Function
Facilitate smooth excursion of the iliotibial tract and gluteal tendons across the prominent greater trochanter
Innervation
Sensory branches of superior gluteal and femoral nerves
Movement & chain
Compressed during hip adduction and side-lying postures
Palpation
Point tenderness directly over the posterosuperior aspect of the greater trochanter
Clinical
Greater Trochanteric Pain Syndrome (GTPS / trochanteric bursitis); severe lateral hip pain aggravated by lying on the affected side, stair climbing, and prolonged standing; often associated with gluteal tendinopathy ('rotator cuff tear of the hip')
Segmental innervation
L4, L5, S1 spinal segments
In clinical practice
Direct trochanteric palpation, single-leg stance test, ultrasound-guided bursal injection, shockwave therapy (ESWT), and progressive gluteal isometric rehabilitation
Region in the model
