Which diagnosis can be best excluded from the differential diagnosis for a patient with persistent hip pain primarily located in the buttock and posterior thigh?

• A. Hip Osteoarthritis
• B. Piriformis Syndrome
• C. Sciatica
• D. Hamstring Strain

Answer: (A)

The diagnosis of hip osteoarthritis can be best excluded from the differential diagnosis for a patient with persistent hip pain primarily located in the buttock and posterior thigh because this condition typically presents with pain that is more localized to the anterior and lateral aspects of the hip, along with a characteristic reduction in range of motion and potential hip joint stiffness. Patients with hip osteoarthritis often report difficulties with internal and external rotation, as well as weight-bearing activities. In contrast, persistent pain in the buttock and posterior thigh is more characteristic of conditions such as piriformis syndrome, sciatica, or hamstring strain. Piriformis syndrome can cause pain that radiates down the leg, mimicking sciatica due to compression of the sciatic nerve by the piriformis muscle. Sciatica, on the other hand, involves nerve root irritation, resulting in pain that typically travels down the posterior leg. A hamstring strain, while it primarily involves pain in the posterior aspect of the thigh, often arises from specific activities and significantly affects movement of the hips and legs. Thus, given the particular location and nature of the pain, hip osteoarthritis is less likely to be the correct diagnosis compared to the other options that align more closely with the patient’s symptoms.
