M89.122
Complete physeal arrest, left proximal humerus
Clinical Classification Guidelines
Medical Intelligence & Overview
Complete physeal arrest of the left proximal humerus is a condition where the growth plate at the top of the upper arm bone (humerus) on the left side ceases to grow. The growth plate, or physis, is a layer of cartilage near the ends of long bones in children and adolescents which allows the bones to grow longer. When this area stops functioning properly, it can affect the growth and development of that part of the bone, leading to potential deformities or discrepancies in arm length. This condition distinctively involves the complete cessation of growth at the involved growth plate, which may result from injury, infection, or other factors, especially in childhood or adolescence.
Causes & Symptoms
Clinical Causes: Trauma or fracture involving the growth plate of the proximal humerus Infections impacting the growth plate (e.g., osteomyelitis) Vascular injuries disrupting blood supply to the growth plate Certain medical conditions or disorders affecting bone growth Previous surgical interventions or treatments affecting the growth area
Key Symptoms: Decreased length or deformity of the affected upper arm Asymmetry between the two arms if only one side is affected Limited shoulder movement or stiffness Pain or tenderness over the affected area (less common in complete arrest) Visible deformity or abnormal contour of the shoulder
Diagnostic & Treatment
Diagnosis Path: Diagnosing complete physeal arrest involves a combination of clinical evaluation and imaging tests. The physician will review the patient's medical history and perform a physical examination, noting any deformity or discrepancy in arm length. Imaging studies, predominantly X-rays, are crucial for visualizing the growth plate and assessing the bone structure. In some cases, MRI scans may be utilized to evaluate soft tissue and cartilage in detail. The absence of growth plate activity and changes in bone structure confirm the diagnosis. Additional tests may be performed to determine underlying causes like infection or vascular issues.
Treatment Protocols: Management of complete physeal arrest depends on the severity of symptoms and the functional impact. Treatment options may include:
