Entheseopathies of the trochanter and pelvis

What are enthesiopathies of the trochanter and pelvis?

The enthesis is the transition zone from tendon or ligament to bone. Overload, unfavorable pressure and tensile forces or degenerative changes can lead to pain, irritation or micro-injuries. In the hip, typical lateral hip pain is now summarized under the term Greater Trochanteric Pain Syndrome (GTPS) - this is often caused by irritation of the gluteal tendon attachments behind the greater trochanter, often accompanied by involvement of the bursa.

• Common: Gluteus medius/minimus enthesis at the greater trochanter
• Also possible: Iliopsoas enthesis on the lesser trochanter (groin/front)
• Adductor entheses on the pubic bone (groin pain, common in athletes)
• Proximal hamstring enthesis at the sciatic tuberosity (ischial bone, pain when sitting/starting)
• Tensor fasciae latae/tractus iliotibialis near the iliac crest (lateral hip)

Anatomy: Tendon attachments around the hip and pelvis

The hip and pelvic area combines strong muscle groups that ensure gait, stability and athletic performance. Their tendons transmit forces to bony prominences - the entheses have to withstand both tension and compression.

• Greater trochanter: Insertion of the gluteus medius and minimus (lateral hip stabilizers).
• Lesser trochanter: Insertion of the iliopsoas (hip flexor).
• Tuber ischiadicum (ischium): origin of the hamstrings.
• Os pubis (pubic bone): Origins of the adductors (adductor longus/brevis, gracilis, etc.).
• Crista iliaca/Spina iliaca (iliac crest): origins, among others. the tensor fasciae latae and the abdominal muscles.

Symptoms: How do enthesiopathies manifest themselves?

Complaints depend on the affected enthesis. Stress-dependent pain, pressure pain on the bony prominence and starting pain are typical. Permanent pain at rest and at night is possible, especially when lying on the painful side.

• Trochanter (gluteal): Stabbing/pulling laterally, increased when lying on the side, climbing stairs, longer marches; often tenderness on the trochanter.
• Iliopsoas (groin/front): Groin pain, pain when standing up from a seat, walking uphill or lifting the leg.
• Adductors (groin/pubic bone): pain when changing direction, sprinting, cutting; Coughing/sneezing can be painful.
• Hamstrings (sitbone/back): Pain when sitting on hard surfaces, starting to run, bending forward.
• TFL/iliac crest: Local pressure pain on the iliac crest when walking/standing for long periods.

Causes and risk factors

There is usually a combination of overloading and incorrect loading. Entheses are sensitive to repeated microtrauma and compression, especially in awkward joint positions. Metabolic and systemic factors can influence tissue healing.

• Sudden increase in training, unusual intensity or change of surface.
• Compression loads: e.g. B. strong adduction (crossing the legs) in gluteal enthesopathy.
• Muscular imbalances, weak hip abductors/external rotators.
• Misalignment/leg length difference, pelvic torsion, change in gait.
• Obesity, repeated prolonged sitting (hamstring approach).
• Hormonal factors (e.g. postmenopausal phase), greater irritability of the tendons.
• Concomitant diseases: rheumatic enthesitis, diabetes mellitus.
• Previous hip/pelvic injury or surgery.

Diagnostics: step by step

The diagnosis is based on anamnesis, targeted examination and – depending on the findings – imaging diagnostics. It is important to differentiate between joint diseases (coxarthrosis, labral lesions) and lumbar causes.

• Anamnesis: localization of pain, stress patterns, night pain, training history, previous illnesses.
• Inspection/gait: Trendelenburg sign, pelvic control, stride width.
• Palpation: tenderness on the greater trochanter, sciatic tuberosity, pubis bone, iliac crest.
• Functional tests: side plank/single leg stand, abduction/adduction/flexion resistance tests, adductor squeeze test.
• Mobility: FADIR/FABER to differentiate intra-articular causes; Thomas test (iliopsoas).
• Ultrasound: Dynamic for assessing tendons, bursae, enthesophytes; helpful for targeted injections.
• X-ray: exclusion of bony changes, calcifications/avulsions.
• MRI: Detailed depiction of tendinopathies, partial tears/tears, edema; useful for unclear/therapy-resistant courses.
• Laboratory: Only if an inflammatory rheumatic cause or infection is suspected.

Differential diagnoses

• Coxarthrosis, femoroacetabular impingement, labral lesion.
• Lumbar radiculopathy, sacroiliac dysfunction.
• Isolated bursitis, external/internal hip snapping.
• Stress reactions/fractures in the pelvic area, avulsion injuries (especially young people).
• Athlete's groin/pubalgia, inguinal hernia, urological/gynecological causes.
• Femoral head necrosis, tumor/infection (rare).

Conservative therapy: The standard approach

Conservative measures lead to significant improvement in the majority of cases. What is crucial is education, targeted stress control and a structured exercise program that is tailored to the affected enthesis.

• Stress management: Temporary reduction of pain-causing activities (e.g. running uphill, sprints, lying on your side on the pain side).
• Everyday adjustment: Do not sit with your legs crossed; Pillow between the knees when sleeping (reduces compression on the trochanter).
• Pain modulation: Short-term NSAIDs/analgesics after medical consultation; local cooling/warming applications depending on tolerability.
• Target exercises (individually dosed):
• - Gluteal (trochanter): isometric abduction, lateral hip stability, external rotation; Progression to weight-bearing exercises (e.g. step-ups).
• - Adductors: Copenhagen adduction variations, isometric adduction, core stability.
• - Hamstrings proximal: isometric hip extension, HSR (Heavy Slow Resistance), hip dominant exercises; Sitting with a soft cushion.
• - Iliopsoas: controlled hip flexor strengthening in a pain-free range; Dose stretching stimuli carefully.
• Manual therapy/soft tissue techniques for tone regulation (supplementary).
• Gait and running style optimization (slightly increase step width, reduce hip adduction).
• Shoe selection/insoles for leg axis/length problems (after examination).

The training plan is controlled in a pain-adapted manner (0-10 scale), usually over 8-12 weeks with progression. The goal is a robust, resilient tendon with good pelvic control.

Complementary interventional procedures

If basic conservative measures are not effective enough, selected interventional therapies can be considered. The decision is made after careful diagnosis, information and under ultrasound guidance.

• Shock wave therapy (ESWT): For GTPS and certain enthesiopathies with moderate evidence; typically in series sessions, combined with an exercise program.
• Targeted infiltrations: Peri-/bursal corticosteroid injections can reduce pain in the short term; the effect is often limited in time. Intratendendinous injections are avoided (risk of tendon weakening).
• Autologous blood/PRP: Evidence mixed; can be discussed in selected cases when basic therapy has been exhausted. Realistic expectations and documentation of progress are important.

We prioritize exercise-modified activation therapy. Interventions are supplements – not replacements – to a structured rehabilitation program.

Surgery: Rarely necessary, clear indication

Surgical treatment is only considered in selected cases - for example, if the symptoms persist despite months of structured therapy or if a severe tendon tear has been proven.

• Endoscopic bursectomy and ITB relief in refractory GTPS.
• Reconstruction/refixation of gluteus medius/minimus ruptures.
• Surgical treatment of proximal hamstring ruptures (especially multilateral tears with loss of function).
• Adductor tenotomy in exceptional cases of chronic pubalgia.
• Iliopsoas release only in strictly selected cases.

The goal, benefits and risks are weighed up in the individual context. A guarantee of freedom from symptoms cannot be given.

Course and prognosis

With consistent, tailored therapy, most enthesiopathies improve within weeks to a few months. Common time horizon: 6-12 weeks for improvement relevant to everyday life, 3-6 months until stable resilience. Relapses are possible, but can be reduced with continued stability and strength training.

• Early information and load control correlate with better outcomes.
• Pain may be moderate during exercise (e.g. up to 3-4/10) and should resolve within 24 hours.
• A maintenance program (2-3 units/week) has a long-term effect.

Self-help: What you can do yourself

• Sleep: lying on your back or side with a pillow between your knees; soft mattress topper can reduce pressure.
• Sitting: Upright posture; Hamstring complaints – soft surface, breaks from sitting.
• Training: Regular, but measured; Increase in small steps (10-15%/week).
• Warm-up and technique: Mobilize before exertion; Check running style (step width, cadence).
• Weight management and general fitness support tendon health.
• Consistent home exercises according to the individual plan.

Sport and return to activity

Sporting activity remains the goal – but in the right dose. The pain-adapted step model supports a safe return.

Special patient groups

• Runners: GTPS and proximal hamstring discomfort by extent/intensity; Increase step width slightly, adjust inclines.
• Ball sports: adductor tendinopathies due to changes of direction/sprints; Core and adductor program essential.
• Postmenopausal patients: more frequent gluteal tendinopathies; Focus on strength/stability, balance.
• Adolescents: apophysitis/avulsions of the pelvis; Consider imaging and protection early.
• Rheumatic diseases: Treat enthesitis systemically; close coordination with rheumatology.

When should you seek medical advice?

• Acute severe pain after trauma, audible “snap/pop”, loss of function.
• Pain at rest/night without improvement for weeks.
• Fever, redness/warmth, general feeling of illness.
• Numbness, weakness, radiation below the knee.
• Unclear groin pain, palpable swelling or hernias.
• Adolescents with sudden pain on the iliac crest/ischium (possible avulsion).
