M85.45

Benign, fluid-filled simple bone cyst common in the proximal femur of growing children.

Clinical Presentation & Protocol

Patient Usually Complains Of

Patient presents with [incidental finding/localized hip pain/limp] localized to the proximal femur. No history of constitutional symptoms, fevers, or night sweats. Pain is described as [dull/aching], exacerbated by [activity/weight-bearing], and relieved by rest. No history of recent trauma or pathological fracture.

Clinical Examination Findings

Hip examination reveals [full/restricted] range of motion. No palpable masses, warmth, or erythema noted over the proximal thigh. Neurovascular status of the lower extremity is intact (distal pulses palpable, sensation intact to light touch). Gait assessment demonstrates [normal/antalgic] pattern. No significant limb length discrepancy.

Treatment Protocol

Management plan includes [observation/serial radiographs/surgical intervention]. If surgical, plan for [aspiration and intralesional bone grafting/curettage/internal fixation] to prevent pathological fracture. Activity modification advised: [avoid high-impact sports/protected weight-bearing] until radiographic evidence of healing or cyst consolidation.
