What FABER test in Hip can tell you is; hip has pathology but CAN NOT specify what the EXACT DISORDER.

-
Many patients report to us with hip and groin pain (usually unilateral) with pain only on crossed sitting and less often with walking stairs, squatting or getting from squatting. FABER test for inguinal pain is positive & SLR is 80 degree suggests that there is no involvement of SI or lumbar spine. I am surprised that it does not match with any common or remote possible pathologies of hip. If FABER is the only sign what the therapist should do? Let us discuss.

The FABER test: Passively flex, abduct, and externally rotate the hip of the lower extremity that is to be tested while subjects is in a supine position, so that the lateral malleolus of the tested lower extremity rests just superior to their opposite extended knee. The test response for hip disorders is an inguinal pain. Similarly the test response for SI disorder is LBA or posterior sacral pain.

For physio researchers: Measurement can be done like the following way: the vertical distance between a fixed mark on the lateral border of the patella of the tested lower extremity and the treatment table can be measured.

Litareture review: According to an article in archives of physical medicine (2008) Strength and ROM testing of the hip in people with hip osteoarthritis can be performed with good to excellent reliability. For hip pain assessment FABER test, log roll test, and assessment of greater trochanteric tenderness were highly reliable and with confidence level (95%). How ever there is a low reliability for the flexion-internal rotation-adduction impingement test. In a study by Mitchell B et al of the 17 patients whose flexion, abduction, external rotation (FABER) test results were reported at the time of examination, 15 (88%) were positive, and 2 (12%) negative on arthroscopy for hip pathology.

Possible interpretations for FABER test:

1. A partial articular pattern; the test position stress the anterior-medial capsule.
2. Muscle tightness; tight flexors of hip, adductors etc.
NB: these structures must be differentiated in a manner suggested by J.Cyriax.

My suggestions: Arthrokinematic correction + muscle stretching.

Entrapment of medial calcaneal nerve (MCN)

Peripheral nerve entrapment is a rare, but important, cause of foot and ankle pain that often is underdiagnosed and mistreated. A peripheral nerve may become entrapped anywhere along its course, but certain anatomic locations are characteristic (2). The medial calcaneal nerve (MCN) The Tibial nerve is called the planter nerve in the sole. The tibial nerve passes to the sole of the foot takes a turn on the medial side of the calcaneum is called MCN. The medial calcaneal nerve arises from tibial nerve of the inner side of the ankle, perforates the laciniate ligament, travels downwards passing below the bony projection on the inner side of the ankle, and supplies the skin over the medial aspect of the heel. Hence it is the most important nerve for heel sensations. MCN have 2 branches. The anterior branch dominate the cutaneous sensation of the anterior part of the medial calcaneal and heel weight loading field, while the posterior branch dominate the sensation of the posterior an

Review of Labral Tears of shoulder

-
Image
The glenoid labrum of the shoulder has extensive anatomic variation but appears to be important for contributing to shoulder stability and for increasing the depth of contact between the glenoid labrum and the humeral head. Tears of the labrum are commonly seen in association with other pathologic entities, such as instability and rotator cuff tears, and treatment of the labral pathology may be incidental to treatment of the other more significant pathology. However, conditions isolated to the labrum do occur and can be a significant source of shoulder problems. Effective treatment of these lesions may result in significant improvement in the patient's symptoms (4). Labral lesions are difficult to diagnose, and special diagnostic studies and, frequently, arthroscopy are required. How much we can rely on clinical tests is a question. Shoulder complaints are frequently recurrent. Instability might cause some of these complaints (3). History taking and clinical tests are commonly used

Differential diagnosis of Anatomic (Radial) snuffbox pain: It is not always DeQuervain’s tenosynovitis.

-

Tendon, Bone & Ligament causes: 1. DeQuervain’s tenosynovitis: Swelling of tendon of APL (Abductor pollicis longus) & extensor pollicis brevis at lateral wrist near anatomic snuff box.  The primary complaint is radial sided wrist pain that radiates up the forearm with grasping or extension of the thumb. The pain has been described as a “constant aching, burning, pulling sensation." Pain is often aggravated by repetitive lifting, gripping, or twisting motions of the hand. Swelling in the anatomical snuff box, tenderness at the radial styloid process, decreased CMC abduction ROM of the 1st digit, palpable thickening of the extensor sheaths of the 1st dorsal compartment and crepitus of the tendons moving from the extensor sheath may be found upon examination. Other possible findings include weakness and paresthesia in the hand. Finkelstein’s diagnostic test will present positive provoking the patient’s symptoms. If left untreated, the inflammation and progressive narro
