M85.011
Fibrous dysplasia (monostotic), right shoulder
Clinical Classification Guidelines
Medical Intelligence & Overview
Fibrous dysplasia is a bone disorder where normal bone is replaced with fibrous tissue, leading to abnormal growth or deformities. Specifically, monostotic fibrous dysplasia affects a single bone, in this case, the right shoulder. This condition typically develops during childhood or adolescence and may cause pain, swelling, or fractures in the affected area. It is a benign condition, meaning it is not cancerous, but it can lead to structural issues that sometimes require medical intervention.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting bone development Most cases are sporadic with no clear hereditary pattern Abnormal proliferation of fibrous tissue replacing normal bone cells Possible involvement of mutations in the GNAS gene, which regulates cell growth
Key Symptoms: Pain or tenderness in the shoulder area Swelling or a palpable bump Weakness or reduced range of motion in the shoulder Uneven shoulder contour or deformity Frequent or stress fractures in the affected bone In some cases, asymptomatic and discovered incidentally during imaging
Diagnostic & Treatment
Diagnosis Path: X-ray imaging: Shows characteristic 'ground-glass' appearance of the affected bone MRI scans: Provide detailed images of bone and surrounding tissues Bone scans: Identify areas of increased metabolic activity consistent with fibrous dysplasia Biopsy: Confirmatory procedure where a tissue sample is examined microscopically to rule out other conditions
Treatment Protocols: Observation: Monitoring the condition if symptoms are minimal and the bone is stable Medications: Bisphosphonates may help reduce bone pain and stabilize the lesion Functional therapy: Physical therapy to maintain range of motion and strength Surgical intervention: Corrective surgery to stabilize fractures, reshape deformed bones, or remove painful lesions Addressing complications: Treating fractures or deformities to preserve shoulder function
