M89.124

Clinical Causes: Trauma or injury to the growth plate, such as fractures or dislocations Infections affecting the bone or growth plate, like osteomyelitis Congenital deformities or developmental abnormalities Bone tumors or neoplastic conditions affecting the growth area Repeated or chronic stress or microtrauma to the shoulder region Previous surgical interventions near the growth plate that may disrupt its function Vascular injury leading to compromised blood supply to the growth plate

Key Symptoms: Possible asymptomatic presentation in early stages Decreased growth or size of the upper arm compared to the unaffected side Visible deformity or abnormalities in shoulder shape Limited range of shoulder motion or stiffness Pain or discomfort in the shoulder, particularly during movement Weakness or instability of the shoulder joint Potential development of limb length discrepancy or angular deformity

Diagnosis Path: Physical examination to assess limb length, deformity, and shoulder mobility X-ray imaging to visualize the growth plate for signs of arrest, deformity, or irregularity Magnetic resonance imaging (MRI) for detailed assessment of soft tissues and to evaluate the cartilage and growth plate integrity Additional imaging or tests if an underlying infection or tumor is suspected

Treatment Protocols: Observation and regular monitoring if the arrest is partial and asymptomatic, especially in growing children Physical therapy to maintain shoulder mobility and strength Surgical interventions such as procedures to correct deformity, stabilize joints, or stimulate growth in select cases Use of orthopedic devices or braces in certain situations to support proper growth or function Addressing underlying causes if identifiable, such as treating infections or removing tumors In cases with significant limb length discrepancy or deformity, more complex reconstructive surgeries may be considered
