Gluteal Tendinopathy (Greater Trochanteric Pain): Adduction Avoidance and Isometric Loading
In short
Lateral hip pain is rarely simple trochanteric bursitis; it is compressive gluteus medius tendinopathy. Learn adduction avoidance rules, sleep setups, and progressive loading.

Deconstructing Greater Trochanteric Pain Syndrome (GTPS)
Lateral hip pain was historically labeled as 'trochanteric bursitis', leading to repetitive, ineffective corticosteroid injections into the trochanteric bursa.
Modern magnetic resonance imaging (MRI) and histological studies have revealed that Greater Trochanteric Pain Syndrome (GTPS) is primarily driven by tendinopathy and partial tears of the gluteus medius and gluteus minimus tendons at their insertion on the greater trochanter, with bursal distension occurring as a secondary bystander.
GTPS disproportionately affects women over 45, characterized by point tenderness over the greater trochanter, severe pain sleeping on the affected side, and pain walking, climbing stairs, or standing on one leg.
The Biomechanics of Compressive Tendon Loading
Tendons tolerate pure tensile loading relatively well; however, combination of tensile strain and compressive loading over a bony prominence is the primary catalyst for degenerative tendinopathy.
Whenever the hip moves into adduction (crossing the midline), the thick, fibrous iliotibial band (ITB) compresses the underlying gluteus medius and minimus tendons directly against the rigid greater trochanter like a taut guitar string across a bridge.
| Daily Activity | Biomechanical Problem (Adduction) | Corrective Modification | Clinical Impact | |
|---|---|---|---|---|
| 1. Side-Sleeping | Top leg falls into deep adduction; bottom hip compressed directly against mattress | Place 2 firm pillows between knees, or sleep on back | Eliminates ITB compression; stops nocturnal waking pain. | |
| 2. Seated Posture | Sitting with legs crossed at knees or thighs | Keep knees slightly wider than hips; feet flat on floor | Maintains neutral hip abduction, reducing tendon shear. | |
| 3. Standing Posture | Standing with weight shifted onto one hip ('hanging on the hip') | Stand symmetrically bearing weight evenly on both feet | Prevents static adduction compression on the loaded side. | |
| 4. Stretching Mistake | Aggressive ITB or piriformis stretches pulling hip into deep adduction | STRICTLY STOP all ITB adduction stretches | Prevents mechanically crushing the inflamed tendon. |
The LEAP Trial Rehabilitation Protocol
The landmark LEAP randomized controlled trial by Vicenzino and colleagues demonstrated that education on load avoidance combined with targeted exercise was significantly superior to corticosteroid injection or wait-and-see approaches.
- Phase 1: Isometric Abduction Analgesia: Supine or seated isometric hip abduction against an inelastic belt (belt around lower thighs, pushing outward gently for 45 seconds, 5 reps), relieving pain via motor cortical inhibition.
- Phase 2: Low-Velocity Isotonic Loading: Side-lying abduction starting from a neutral or slightly abducted position (using a pillow under the knee, never allowing the leg to drop into adduction) and standing resisted banded side-steps.
- Phase 3: Functional Weight-Bearing Stability: Single-leg bridging, step-ups, and mini-squats ensuring zero Trendelenburg pelvic drop.
- Avoid Clamshells Initially: Standard clamshell exercises place the hip in combined flexion and internal rotation, compressing the tendon; side-lying straight leg abduction in slight extension is preferred.
Indian Household and Floor Seating Adaptations
Sitting cross-legged on the floor (sukhasana) or rising from low Indian stools forces extreme hip flexion and adduction, creating high compressive loads on the gluteal tendons.
Physiotherapists prescribe elevated chairs (seat height slightly above knee level) and advise against floor sitting during the initial 8 to 12 weeks of active tendon recovery.
Frequently Asked Questions
Why do cortisone injections often fail in lateral hip pain?
Cortisone reduces short-term inflammation in the bursa, providing 2 to 4 weeks of temporary relief. However, it does not heal the underlying gluteal tendon pathology and can further weaken tendon collagen, leading to high recurrence rates.
How should I sleep if both hips hurt?
Sleep on your back with a pillow under your knees. If you must sleep on your side, sleep on the less painful side with two thick pillows between your knees and ankles to prevent the top hip from sagging into adduction.
What is the single-leg stance test for gluteal tendinopathy?
Standing on the affected leg for 30 seconds: if lateral hip pain develops within 30 seconds, it has a 97 percent specificity for confirming gluteal tendinopathy.
