“…The pattern for protective tone may be categorized into the Lower Cross Syndrome as described by Janda [44] or adductor tone in response to hip pain and inhibition of primary hip stabilizers which is clinically consistent in this group of patients. As described previously, Green demonstrated the extensive function of the adductor group [38]. Therefore, it is understandable that in the presence of pain, the adductor group would respond to assist in protection and stabilization.…”

“…The mechanism may be acute, traumatic, overuse tendinosis or developmental avulsions [37]. Casartelli et al [38] report that patients with FAI presented with decreased maximal voluntary contraction levels for the hip adduction (28%), flexion (26%), external rotation (18%) and abduction (11%) when compared with the control group, demonstrating the contractile dysfunction occurring as a result of structural pathology and pain. The tensor fascia lata (TFL) also demonstrated decreased activation during hip flexion in the hip diagnosed with FAI.…”

The level of understanding of pain in the nonarthritic hip has made significant strides in the last couple of decades beginning with the discoveries of Reinhold Ganz, MD. However, even with the detection of subtle bony abnormalities, including femoroacetabular impingement, a clinician's ability to differentiate pain generators in the hip has been ambiguous. Deciphering the etiology of the pathology versus the pain generator is essential in prescribing the proper treatment. The Layer Concept developed by Dr. Bryan Kelly, is a systematic means of determining which structures about the hip are the source of the pathology, which are the pain generators and how to then best implement treatment. Four layers will be discussed in this article. Layer I, the osseous layer, Layer II, the inert tissue layer, Layer III, the contractile layer and Layer IV, the neuromechanical layer.

“…While the tensor fasciae latae muscle is less commonly injured than the other hip abductors [17], a recent report using electromyographic recordings showed that patients with symptomatic femoroacetabular impingement had a reduced ability to activate the tensor fasciae latae muscle during hip flexion [18], showing that the tensor fasciae latae can undergo changes due to a different weight loading.…”

OBJECTIVE: To evaluate the association between hypertrophy of the tensor fasciae latae muscle and abductor tendon tears. MATERIALS AND METHODS: Thirty-five patients who underwent MRI of the abductor tendons of the hip were included in this retrospective study. A subgroup of 18 patients was examined bilaterally. The area of the tensor fasciae latae muscle and the area of the sartorius muscle (size reference) were quantified at the level of the femoral head, and a ratio was calculated. Two radiologists assessed the integrity of the gluteus medius and minimus tendon in consensus. Data were analyzed with a Mann-Whitney U test. RESULTS: Sixteen out of 35 patients (46 %) had a tear of the gluteus medius or minimus tendon. The ratio of the area of the tensor fasciae latae to the sartorius muscle was significantly higher (p = .028) in the group with an abductor tendon tear (median 2.25; Interquartile Range [IQR] = 1.97-3.21) compared to the group without any tears (median 1.91; IQR = 1.52-2.26). The bilateral subanalysis showed that in patients without a tear, the ratio of the two areas did not differ between each side (p = .966), with a median of 1.54 (primary side) and 1.76 (contralateral side). In patients with an abductor tendon tear the ratio was significantly higher (p = .031) on the side with a tear (median 2.81) compared to the contralateral healthy side (1.67). CONCLUSION: Patients with abductor tendon tears showed hypertrophy of the tensor fasciae latae muscle when compared to the contralateral healthy side and to patients without a tear.

“…Since lateral balance is controlled by coordinated hip muscle activity and trunk movement (12), reduced hip muscle strength (13,14) and limited hip joint range of motion (ROM) observed in those with hip OA may contribute to impaired balance control. Importantly, younger individuals with hip pathol-ogy also exhibit reduced hip strength and ROM (15), which may render these individuals at risk of impaired balance control.…”
