A middle aged male presented with complaints of pain in the
right gluteal region. The pain started spontaneously and hampered him from
walking. The pain was worse with movement especially in getting up from sitting
and climbing stairs. It was relieved temporarily with the use of NSAIDs. There
was no associated back pain, no pain on the anterior or medial aspect of the
thigh or below the knee. There was no history of numbness or paresthesias. On
examination pain was reproduced particularly during flexion, adduction and
internal rotation of the hip. There was no local tenderness and no obvious
lesions on the skin.
What is the possible
cause?
A principle that I follow in evaluating pain is to first
think of the possible structures that could be the origin of the patient’s
pain. Pain in the gluteal region may arise from the skin, subcutaneous tissue,
muscles in the region, joints, bone, nerve or the spinal roots.
An infection in the cutaneous or subcutaneous plane:
Furuncle, Abscess, Bursitis
Muscle: Myofascial strain, Myositis
Joint: Sacroiliitis, sacroiliac joint dysfunction
Bone: Osteomyelitis
Nerve: Sciatic nerve compression
Roots: Lumbar Radiculopathy secondary to root compression
How to evaluate the
patient?
Local examination: Inspection & Palpation: Check for
tenderness, muscle tightness
Move: Range of motion
Stress tests for the sacroiliac joint
Tests for piriformis syndrome
Neurological examination to check for radiculopathy &
sciatic nerve dysfunction
Imaging to look for structural pathology
Special tests: SPECT/Magnetic resonance neurography
