Gluteus minimus tendinopathy

Anatomy: Role of the gluteus minimus

The gluteus minimus is the smallest of the three glute abductors (along with the gluteus medius and maximus). It arises from the outer iliac blade and attaches via its tendon to the anterior aspect of the greater trochanter. Functionally, together with the gluteus medius, it stabilizes the pelvis when walking and running, ensures abduction and - depending on the hip position - internal rotation.

The trochanteric bursa and the iliotibial tract are in the immediate vicinity. Irritation of the tendon and bursa often occur together and cause similar symptoms.

• Insertion: anterior/anterolateral greater trochanter
• Task: Abduction, pelvic stability in the stance phase, internal rotation
• Neighborhood: gluteus medius tendon, trochanteric bursa, iliotibial band

Complaints and typical symptoms

• Stitching or burning pain on the outside of the hip above the greater trochanter
• Tenderness over the anterior/lateral trochanter
• Increase in pain when lying on your side, climbing stairs, walking uphill or standing for long periods
• Pain when standing on one leg; Possibly limping gait (Trendelenburg/Antalgia)
• Radiation along the outside of the thigh (usually not below the knee)
• Pain provocation during adduction (crossing the legs), during rapid changes of direction or jogging

Many sufferers report nighttime pain and sleep problems. Abductor strength deficits and increased tendon sensitivity (tendinopathy) are often detectable.

Causes and risk factors

Gluteus minimus tendinopathy usually arises from a combination of overload and increased compression of the tendon at its insertion - often promoted by unfavorable movement patterns and weak abductors.

• Repetitive or increased stress (walking, running, uphill, intensive classes, sudden increases in training)
• Compression stress on the tendon: prolonged sitting with crossed legs, lying on the side without a pillow, sustained adduction
• Biomechanical factors: leg axis deviations, foot pronation, leg length difference, pelvic/trunk control weakness
• Degenerative changes with age, hormonal influences
• Concomitant diseases: diabetes, thyroid diseases; Smoke
• Previous operations on the hip, e.g. B. after hip prosthesis (change in biomechanics)

Differentiation from other causes of pain on the outside of the hip

• Gluteus medius tendinopathy or partial tear
• Trochanteric bursitis
• Iliotibial band irritation (iliotibial band syndrome)
• Lumbar spine-related pain/radiculopathy
• Coxarthrosis (hip joint arthrosis)
• Iliopsoas problems (tendinitis, snapping)
• Sacroiliac joint dysfunction
• Proximal hamstring tendinopathy (tuber ischiadicum)

The exact diagnosis is important because therapy and prognosis vary depending on the structure. A careful examination and, if necessary, sonography/MRI help with differentiation.

Diagnostics: anamnesis, examination and imaging

The diagnosis is based on the combination of symptoms, clinical tests and imaging findings. We specifically check pain points and the resilience of the abductors.

• Inspection/gait: side bending, Trendelenburg sign, shortening of stride
• Palpation: tender point on the anterior facet of the greater trochanter (typical for gluteus minimus)
• Stress tests: one-legged stance (30–60 s), isometric abduction, resistance to internal rotation in flexion
• Provocation through adduction (e.g. FADER position) and stretching positions
• Sonography: tendon thickness, structure, enthesopathy; Power Doppler for activity; Assessment of the bursa
• MRI: in case of refractory treatment or suspected partial/complete tear, differentiation to gluteus medius
• X-ray of the hip if osteoarthritis or bony changes are suspected
• Diagnostic test injection (local anesthetic) can narrow down the source of the pain

Warning signs such as fever, pain at night when resting unrelated to exertion, neurological deficits or recent trauma require prompt medical evaluation.

Conservative therapy: first load control and training

In most cases, gluteus minimus tendinopathy can be treated conservatively. Central to this is adapted load management and structured, progressive abductor training, supplemented by education on compression positions to avoid.

• Load adaptation: temporary reduction in repetitive loads (uphills, sprints, jumps), pain-adapted activity instead of complete rest
• Compression reduction: do not cross your legs when sitting; when lying on your side, pillow between your knees; Avoiding deep adduction
• Short-term pain therapy after consultation: local cooling/warming, if necessary NSAIDs for a few days
• Physiotherapy: isometric abduction exercises against the wall, later eccentric-concentric strengthening; Pelvic/trunk stability
• Motor learning/gait school: Slightly increase step width, reduce hip adduction while standing
• Soft tissue techniques/manual therapy to relieve pain and improve function
• Leg axis/foot: if necessary, insoles for severe overpronation, suitable shoes
• Everyday coaching: carry loads on both sides, avoid standing for long periods in “hip position”.

Shock wave therapy (ESWT) can be considered as an adjunct in treatment-resistant gluteal tendinopathy. The evidence shows an improvement in pain and function in selected patients. The decision is made individually.

The aim is to gradually increase the resilience of the tendon over weeks. Symptoms should remain tolerable under training load (e.g. pain up to 3/10) and return to baseline levels within 24-48 hours.

Injection and regenerative procedures: when does it make sense?

If sufficient improvement does not occur after 6-12 weeks of structured conservative therapy, ultrasound-guided injections may be considered. They do not replace active rehabilitation, but can accompany it.

• Peritendinous/bursa injection (e.g., corticosteroid): may provide short-term pain relief; Repeated injections should be avoided due to potential tendon weakening.
• PRP (platelet-rich plasma): studies have shown some positive effects on gluteal tendinopathies; Evidence moderate and heterogeneous. Use after careful information and if conservative standard therapy fails.
• Local anesthetic test injection: diagnostic to localize the source of pain.
• Hyaluronic acid or autologous blood: currently no clear evidence for standard use.

When indicated, we prefer to carry out injections with ultrasound support in order to hit the target structure and protect surrounding tissue.

Surgical options: rarely necessary

Surgery is only considered if guideline-based conservative therapy has been unsuccessful for months (usually 6-12) and imaging shows a significant partial or complete tear or therapy-resistant inflammation/compression.

• Endoscopic/open tendon reattachment for gluteus medius/minimus tears
• Bursectomy and selective ITB decompression for severe mechanical irritation

After surgical treatment, several months of rehabilitation can be expected. Whether an intervention makes sense depends on the findings, symptoms, activity goals and comorbidities.

Course and prognosis

With consistent education, load control and targeted strengthening, most gluteus minimus tendinopathies improve significantly within 6-12 weeks. Some courses take longer, especially if the symptoms are already chronic or several factors are involved (e.g. lumbar spine, leg axis).

• Return to pain-limited everyday activities usually within a few weeks
• Sport-specific loads are built up gradually; Only increase the amount of running you do if you respond well to training stimuli
• Relapse prevention: long-term abductor training and attention to avoiding compression

Safe exercises to get you started

The following examples are general and do not replace individual instructions. Train in a way that adapts to pain. A pulling sensation is tolerable, but stabbing pain is not.

• Make sure your stride is slightly wider when walking and avoid “slumping” your hips.
• Initially avoid stretching positions with strong adduction (crossing the legs), later use moderate and low-pain amounts.

Everyday life and prevention

• Do not cross your legs constantly when sitting
• Lie on your side with a pillow between your knees
• Regular, progressive strengthening of the hip abductors and core muscles
• Training increases moderate (rule of thumb: do not exceed 10% per week)
• Suitable footwear, possibly insoles in case of significant overpronation
• Warm up before exercise, cool down afterwards
• Weight management and breaks at the first warning signs

When should I seek medical advice?

• Severe pain or significant loss of function or strength
• Pain at rest at night without reference to exertion
• Newly occurring sensory disturbances, paralysis or radiation down to below the knee
• Fever, redness, overheating or after a recent fall/trauma
• Despite adjustments to everyday life and training, symptoms persist for >4–6 weeks
