Hip Pain: Causes and Differential Diagnosis

Explore serious pathologies that cause hip and buttock pain, including proximal arteries and vascular issues, visceral infections and malignancies, spondyloarthropathies, fractures and avulsions, and statin-related muscle spasms.

Explore vascular causes of hip to lower limb pain, detailing lower extremity arterial disease and claudication from iliac and femoropopliteal occlusions, and distinguish true from pseudo claudication.

Explore how visceral disorders refer pain to the hip region, presenting as diffuse back pain that does not change with activity, with night pain and specific organ referral patterns.

Explore fractures of the pelvis and hip, including sacral, pubic ramus, acetabular, femoral neck, and stress fractures, with emphasis on risk factors, avascular necrosis, and diagnostic approaches.

Investigate axial spondyloarthropathy and seronegative spondyloarthropathies, focusing on spine and Si joints involvement, HLA-B27 positivity, and enthesitis. Learn early diagnosis, differential features, CPR, and the gender differences impacting patient journeys.

Assess statin associated muscle symptoms (SAMS), including myalgia, myopathy, and rhabdomyolysis risk, with nocebo considerations, differential diagnoses, and management via statin cessation or dose adjustment.

Examine lumbar radiculopathy, differentiate it from posterior hip pain, and review key tests like the straight leg raise and slump test, plus emerging clinical prediction rules for diagnosis.

Identify thoracolumbar involvement as a potential source of posterior hip pain, including Maine syndrome and superior cluneal nerve impingement, with referral patterns to groin, abdomen, and buttock.

Identify sacroiliac dysfunction through SI joint-related pain patterns worsened by sit-to-stand and single-leg stance. Apply Laslett's five SI joint tests, noting limited rule-in accuracy and 92% rule-out with negative results.

Explore posterior syndromes of the buttock and sciatic nerve entrapment, with emphasis on piriformis syndrome diagnosis, differential diagnoses, clinical tests, and conservative to surgical treatment options.

Identify deep gluteal syndrome as a non-disc, extra pelvic entrapment of the sciatic nerve within the deep gluteal space, involving piriformis, gemelli, and obturator internus.

Soft tissue issues, including muscles, tendons, and fascia, can cause posterior buttock pain from overloading or rest loading; pain eases with warming up but recurs after cooling.

Explore posterior hip joint pain due to pathology, osteonecrosis, and chondrolabral disease, with instability linked to anterior impingement and hypermobility. Manage with rest, NSAIDs, injections, and targeted physical therapy.

Explore anterior and lateral hip pathology, revisit hip osteoarthritis and knee referral patterns, and examine labral tears, femoroacetabular impingement, hip laxity, inguinal ligament disruption, and cutaneous nerve impingement.

Explore osteoarthritis of the hip, its diverse pain patterns (groin, buttock, thigh, knee), imaging and grading, plus a five-variable clinical prediction rule whose validation remains uncertain.

Explore how knee osteoarthritis reduces hip and ankle range of motion, increases ankle varus, and elevates knee adduction, illustrating the knee's impact on the proximal joints.

Explore hip labral pathology and how the labrum stabilizes and seals the acetabulum to protect cartilage, transfer loads, and explain groin and knee-related pain with the C sign.

FAI, a motion-related hip disorder with cam and pincer morphologies, risks hip osteoarthritis; diagnosis combines symptoms, clinical signs, and imaging, with treatment spanning conservative care, rehabilitation, and surgery.

Examine hip joint laxity and its causes, including connective tissue disorders causing hypermobility, such as Ehlers-Danlos syndrome and hypermobility spectrum disorder, and trauma or surgical damage.

Explore anterior groin disorders such as inguinal ligament disruption, inguinal hernia, and anterior nerve impingement, outlining hallmark signs, differential diagnoses, and first-line physical therapy strategies.

Introduce gtps, the greater trochanter pain syndrome, as the primary cause of lateral hip pain, potentially involving bursitis, inflamed tendons, or surrounding muscles with moderate to severe pain on palpation.

The clinical presentation of greater trochanter pain syndrome affects midlife athletes, especially females, with higher BMI. It features lateral hip pain with tenderness, provoked by weight-bearing tasks and single-leg stance.

Reveal how hip adduction, single-leg dynamics, and iliotibial band compression drive greater trochanteric pain syndrome (gtps), with gluteus medius/minimus weakness, abductor mechanism balance, and pelvic mechanics as key factors.

Review external snapping hip and lateral femoral cutaneous or iliohypogastric neuropathies; diagnose with neurodynamic testing using hip extension and adduction, plus trunk movements.

Learn to use outcome measures and functional assessment tools to diagnose and treat greater trochanter pain syndrome, including Who's Hip survey, Womac, and I heart 33.

Evaluate greater trochanter pain syndrome using a full battery of objective tests, including palpation, resisted hip movements, and passive adduction, to differentiate gluteal tendinopathy and confirm diagnosis.

Educate patients on load management for lateral hip pain. Monitor activity, sleep position, and avoid adduction stretches and clamshells when gtps is present.

Explore treatment concepts for hip pain, from acute low intensity isometrics and analgesia to subacute progressive isotonic loading, strengthening, and pelvic control to limit hip abduction.

Corticosteroid injections offer short-term relief but may raise recurrence and hinder tendon loading. If conservative treatment fails and MRI suggests a tear, open or endoscopic surgery can improve outcomes.
