“…The greater trochanteric pain syndrome is characterized by chronic pain and tenderness over the greater trochanter [1,2]. Notably, this syndrome can present both in patients with and without total hip arthroplasty (THA), and it is commonly caused by abductor tendon abnormalities [1,[3][4][5].…”

“…In addition to severe lateral hip pain, abductor tendon tears and atrophy of the associated muscles often result in further clinical problems such as a Trendelenburg gait pattern, or immobility [6]. MRI is routinely used for evaluation of suspected abnormalities of the gluteus medius and minimus tendon and muscle, both in patients with and without THA, and with the routine use of MRI the knowledge about abductor tendon abnormalities has increased in recent years [3,1,2,7,8]. However, the biomechanics of the development of abductor tendon tears are still poorly understood, and the role of the tensor fasciae latae muscle in the development of abductor tendon tears has not been evaluated up to date [8].…”

Abductor tendon tears are associated with hypertrophy of the tensor fasciae latae muscle

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.

“…One reason abductor tears are under recognized is due to the difficulty in diagnosing them. Kagan et al reported no diagnostic findings on physical examination in patients with abductor tears [9] and plain radiographs are typically negative [10,11]. The Trendelenburg sign is the most sensitive and specific physical sign for the detection of gluteus medius tears [5].…”

This is a retrospective, consecutive, single-surgeon case series which examines the clinical and radiographic outcomes of 19 hips with the incidental finding of hip abductor tears during primary Total Hip Artroplasty (THA). The incidence of abductor tears was 0.68% during our study period from 1994 -2008. We found that positive preoperative Trendelenburg gait was a positive predictor of the presence of an abductor tear. Seven out of 19 patients had an intraoperative change in surgical approach due to the extent of the abductor tear. Bilaterality and the presence of sclerosis preoperatively were significantly associated with a longer limp period postoperatively. In conclusion, idiopathic abductor tears are rare during primary THA, however there is a high likelihood of changing the intraoperative approach if they are encountered.

MRI Diagnosis of Tears of the Hip Abductor Tendons (Gluteus Medius and Gluteus Minimus)

Abstract: MRI showed good accuracy for the diagnosis of tears of the gluteus medius and gluteus minimus tendons. The identification of an area of T2 hyperintensity superior to the greater trochanter had the highest sensitivity and specificity for tears at 73% and 95%, respectively.
