Diagnosis of hip pathology is challenging. An avg. 3.3 providers before being correctly diagnosed.
False positive with MRI and MRA are common.
Accurate and efficient physical examination is valuable.

Squeeze Test SN 43% SP 91% PATHOPHYSIOLOGY
Pathophysiology of OA (cartilage):
Structural framework of cartilage comprises:
Collagens
Proteoglycans
Glycoproteins
Tissue fluid (cations)
Glycosaminoglycans (anions) GAG’s. PATHOPHYSIOLOGY
Cartilage histology: architecture and matrix composition will provide Dx objectives.
Superficial zone: 1st affected by OA. Low GAG, high Collagen content, parallel to surface.
Middle Zone: higher GAG. Col oblique.
Deep zone: High GAG. Col perpendicular.
Tidemark transition into subchondral bone. PATHOPHYSIOLOGY
OA Research Society International (OARSI) grading:
Grade I and II: Cartilage oedema and early GAG depletion. Some superficial fissuring.
Grade III: Vertical fissures into middle zone. No significant cartilage loss. Still reversible. IMAGING.
Grade IV: increased fissuring, cartilage erosion
Grade V and VI: almost complete erosion of articular cartilage. Sclerosis.
Pritzker KP, Gay S, Jimenez SA, et al. , Osteoarthritis cartilage histopathology: grading and staging. Osteoarthritis Cartilage 2006;14;13-29. IMAGING
XRAY:
Most common Dx method for OA.
Narrowing joint space (most sensitive), osteophyte formation, subchondral sclerosis and cysts.
Kellgren and Lawrence grading.
Kellgren JH, Lawrence JS. Radiological assessment of osteo-arthrosis. Ann Rheum Dis 1957: 16:494-502. IMAGING
While MR arthrography has been advocated for the evaluation of labral pathology, this technique requires intraarticular administration of gadolinium-based contrast, a procedure that is not without risks. IMAGING
XRAY views for Hip:
Systematic review of Xray assessment of the YOUNG HIP considered (ANCHOR):
AP view
Cross table lateral view
Dunn view 45* or 90*
Frog leg view
False profile view
Clohisy JC et al., A Systematic Approach to the Plain Radiographic Evaluation of the Young Adult Hip. J Bone Joint Surg Am. 2008;90 Suppl 4:47-66. IMAGING
Longitudinal assessment using quantitative MRI will allow for the establishment of quantitative threshold values of the dGEMRIC (Delayed Gadolinium Enhanced MRI of the Cartilage) index, T2 relaxation time, or T1ρ (Spin lattice relaxation in the rotating frame) that are predictive of osteoarthritis and joint degradation that require arthroplasty. IMAGING
ULTRASOUND
Particularly useful in Dx hip effusion: clinical relevance in Toxic Synovitis or Septic Arthritis.
Doppler can reveal synovial vascularity. Synovitis could be a predictive factor for OA. ANTERIOR HIP
