High Index Of Suspicion

Obturator abscess is a rare condition in children which usually occurs commonly in tropical countries. Because of its rarity, vague symptomatology and a lack of focus about this condition, the diagnosis of obturator abscess is commonly delayed or missed. Hence, physicians should be familiar with this condition and have a high index of suspicion when a patient presents with fever, pain in the thigh, hip or abdomen and a limp on the affected side which are considered as the classic clinical triad of obturator abscess. Herein, we present a 6-year-old previously healthy Russian boy who was on holiday in Sri Lanka. He presented on the third day of the fever associated with pain in the right thigh and abdomen. This is the first reported case of an obturator externus muscle abscess due to methicillin-resistant Staphylococcus aureus in a European boy visiting a tropical country.

Acetabular Defects

AbstractReconstruction of acetabular defects in revision total hip arthroplasty (THA) requires excellent exposure. Most extensile approaches to the acetabulum were described in the trauma literature and are not beneficial for revision THA. This article describes a modification of the standard posterior surgical approach to improve visualization of the ischium as required for acetabular defect reconstruction, insertion of standard and custom triflange cages as well as posterior column plating. The current surgical technique utilizes an intermuscular plane between the gemellus inferior muscle and the obturator externus muscle. This intermuscular plane leads the surgeon directly to the ischium and facilitates easy extension toward the insertion of the hamstring muscles without compromising the insertion of the external rotator muscles along the ischium. This article describes a novel surgical approach to the posterior column and ischium under special consideration of the sciatic nerve, superior gluteal vessels, and medial femoral circumflex artery. This simple extension of the standard posterior approach optimizes exposure of the posterior column during revision THA using a posterior approach.

Quadratus Femoris

Context: Muscle injuries of the hip stabilizers are considered rare in sport. Objective: This report presents a previously unreported case of a contact injury resulting in acute strain of quadratus femoris, obturator externus, and inferior gemellus in an amateur Australian rules football player. Design: Level 4—case report. Case Presentation: A player was tackled ipsilateral to the injured leg, while in hip flexion in a lunged position. The case describes the diagnostic process, initial management, and return to play for this athlete. Results: Following rehabilitation, the player was able to return to sport at 8 weeks without ongoing issues. Conclusions: A literature search for sports-related contact injuries to either muscle returned only one result. All other documented cases of injury to these muscle groups are confined to noncontact mechanisms or delayed presentations. Despite conventional teaching, the action of the deep external rotators of the hip appears to be positionally dependent. Knowledge of this type of injury and mechanism may be useful for future clinical reasoning and differential diagnosis in patients with this type of presentation.

Species Specific

We examined the six small lateral rotators of the hip joint, which is one of the most flexible joints and allows kinematically complex motions of the hindlimb, to elucidate the functional differentiation among these muscles and to test the hypothesis that species-specific characteristics in hindlimb use during locomotion are reflected in the muscle spindle density and in other parameters of the deep small hip joint rotators. For these purposes, we estimated the number of muscle spindles of the superior gemellus muscle (SG), inferior gemellus muscle, quadratus femoris muscle, obturator internus muscle (OI), obturator externus muscle, and piriformis muscle in three Japanese macaques and a gibbon, using 30-µm-thick serial sections throughout each muscle length after azan staining. The numbers of muscle spindles per 10,000 muscle fibers were determined to compare inter-muscle variation. The spindle density was highest in the SG and lowest in the OI in the Japanese macaques, suggesting that the SG, which is attached to the tendon of the OI, functions as a kinesiological monitor of the OI. On the other hand, SG the was missing in the gibbon, and the OI in the gibbon contained more spindles than that in the Japanese macaques. This suggests that the SG and the OI fused into one muscle in the gibbon. We postulate that the relative importance of the deep small hip rotator muscles differs between the Japanese macaques and gibbon and that the gibbon’s muscles are less differentiated in terms of the spindle density, probably because this brachiating species uses its hindlimbs less frequently.
