M87.145
Osteonecrosis due to drugs, left finger(s)
Clinical Classification Guidelines
Medical Intelligence & Overview
Osteonecrosis, also known as avascular necrosis, is a condition characterized by the death of bone tissue caused by a lack of blood supply. When this condition is linked to drug use and occurs in the finger, it becomes a specific health concern. ICD-10 code M87.145 designates osteonecrosis due to medication effects in the left finger(s). This condition can impair finger function and cause pain, stiffness, and deformity if not properly managed. Though not common, it highlights the importance of understanding medication side effects and their impact on bone health.
Causes & Symptoms
Clinical Causes: Use of corticosteroids or high-dose steroid therapy Long-term use of certain medications like anticoagulants or chemotherapeutic agents Medication-induced vascular changes leading to reduced blood flow to bones Drug toxicity affecting bone marrow and blood vessels in the finger bones
Key Symptoms: Pain in the affected finger(s), especially with movement or pressure Swelling and tenderness around the finger joints Decreased range of motion or stiffness in the finger Discoloration or pallor of the skin over the affected area Possible deformity if the condition progresses Weakness or numbness in the finger if nerve involvement occurs
Diagnostic & Treatment
Diagnosis Path: Medical history review, focusing on medication use Physical exam assessing pain, swelling, and joint mobility X-ray imaging to detect bone destruction or collapse Magnetic Resonance Imaging (MRI) to evaluate bone marrow and detect early changes Bone scans or other advanced imaging if necessary
Treatment Protocols: Discontinuation or adjustment of the causative medication, under medical supervision Pain management through NSAIDs or other pain relievers Immobilization of the affected finger to reduce stress on the bone Physical therapy exercises to maintain finger mobility and strength Surgical intervention in advanced cases, such as core decompression or joint replacement Preventive measures, including regular monitoring if using high-risk medications
