M21.2
Flexion deformity
Clinical Classification Guidelines
Medical Intelligence & Overview
Flexion deformity is a condition characterized by the abnormal bending of a joint, which results in restricted movement and can cause discomfort or functional limitations. It often develops due to various underlying health issues, injuries, or degenerative processes affecting the joints and surrounding tissues. Recognized under ICD-10 code M21.2, this condition primarily impacts the knee but can affect other joints as well.
Causes & Symptoms
Clinical Causes: Arthritis, especially osteoarthritis, leading to joint damage and deformity Previous injury or trauma to the joint or surrounding tissues Congenital joint deformities present at birth Joint infections causing inflammation and damage Prolonged immobility or disuse of the joint Degenerative diseases affecting the joint tissues Scar tissue formation after surgery or injury Neuromuscular disorders leading to abnormal muscle tone and joint positioning
Key Symptoms: Limited range of motion in the affected joint Persistent or recurring joint stiffness Visible abnormal joint positioning or swelling Pain or discomfort during movement Muscle weakness surrounding the joint Difficulty performing daily activities involving the affected joint Potential deformity or joint misalignment
Diagnostic & Treatment
Diagnosis Path: The diagnosis of flexion deformity involves a detailed medical history and physical examination. Healthcare providers assess joint mobility, observe deformities, and evaluate muscle strength. Imaging tests such as X-rays help visualize joint structure, identify degenerative changes, or confirm the presence of deformities. Additional tests may be necessary to evaluate underlying causes, such as blood tests for inflammatory conditions or MRI scans for soft tissue assessment.
Treatment Protocols: Treatment for flexion deformity focuses on improving joint mobility, relieving pain, and addressing underlying causes. Approaches may include:
