M87.133
Osteonecrosis due to drugs of unspecified radius
Clinical Classification Guidelines
Medical Intelligence & Overview
Osteonecrosis, also known as avascular necrosis, is a condition that occurs when there is a loss of blood supply to the bone. In the specific case coded as M87.133, the osteonecrosis is attributed to the use of certain drugs, affecting the radius in the forearm. This condition can lead to bone tissue death, resulting in joint pain, decreased mobility, and potential bone collapse if not managed properly. The term 'unspecified radius' indicates that the medical records do not specify which side of the forearm is affected. Understanding the causes, symptoms, and treatment options can help in managing this condition effectively.
Causes & Symptoms
Clinical Causes: Use of corticosteroids or other medications that impair blood supply to bones High-dose or prolonged drug therapy Other risk factors that diminish blood circulation within the bone tissue Underlying health conditions that predispose bones to ischemia
Key Symptoms: Gradual onset of joint pain, especially in the forearm or wrist Swelling and tenderness around the affected area Reduced range of motion or stiffness in the wrist or forearm Possible development of joint collapse or deformity over time Symptoms may initially be mild but can progress to significant discomfort and disability
Diagnostic & Treatment
Diagnosis Path: Medical history review focusing on medication use and onset of symptoms Physical examination assessing joint function and tenderness Imaging studies such as X-rays to detect bone damage or collapse MRI scans providing detailed images to identify early stages of osteonecrosis Bone scans or other laboratory tests if underlying causes need to be explored
Treatment Protocols: Discontinuation or adjustment of causative medications under medical supervision Pain management strategies including NSAIDs or other pain relievers Physical therapy to maintain joint mobility and strengthen surrounding muscles Surgical options such as core decompression, bone grafts, or joint replacement in advanced cases Lifestyle modifications to reduce stress on the affected bone and improve overall bone health
