M21.922
Unspecified acquired deformity of left upper arm
Clinical Classification Guidelines
Medical Intelligence & Overview
An acquired deformity of the upper limb refers to any abnormal shape or structure that develops after birth, affecting the arm's normal alignment or function. Specifically, the ICD-10 code M21.922 describes an unspecified acquired deformity of the left upper arm. This condition involves alterations in the arm's shape or structure that are not congenital, meaning they are not present at birth but develop later due to injury, disease, or other factors. Such deformities can impact movement, strength, and appearance, potentially affecting daily activities and quality of life.
Causes & Symptoms
Clinical Causes: Trauma or injury leading to bone fractures or soft tissue damage Infections causing inflammation and subsequent deformity Previous surgeries that result in scarring or misalignment Degenerative diseases affecting joints and bones Nerve injuries resulting in muscle weakness or imbalance Tumors or growth abnormalities over time Neuromuscular conditions leading to abnormal muscle development Repeated or unresolved fractures evolving into deformities
Key Symptoms: Visible deformity or abnormal contour of the upper arm Limited range of motion or stiffness in the shoulder or elbow Pain or discomfort in the affected area Weakness or lack of strength in the arm Swelling or localized tenderness Altered function, making activities like lifting or reaching difficult Changes in skin texture or color over the deformity Muscle wasting or atrophy in severe cases
Diagnostic & Treatment
Diagnosis Path: Physical assessment to evaluate the deformity's extent and impact X-rays to visualize bones, confirm deformity, and identify fractures or abnormalities MRI or CT scans for detailed imaging of soft tissues and complex deformities Electromyography (EMG) if nerve or muscle involvement is suspected Assessment of functional limitations and impairment
Treatment Protocols: Rehabilitative therapy, including physical and occupational therapy, to improve movement and strength Pain management strategies, possibly including medications or modalities like heat or cold therapy Orthopedic procedures or surgeries to realign bones, repair soft tissues, or correct deformity Splinting or bracing to support proper positioning during healing Addressing underlying causes, such as infection or nerve injury Post-treatment rehabilitation to maintain and enhance functional gains
