S43.111

Clinical Causes: Direct trauma or blow to the shoulder, such as falling onto the shoulder or an impact during contact sports Falling onto an outstretched hand with force transmitted to the shoulder Sudden or excessive lifting of heavy objects that strain the shoulder joint Accidental collisions or falls that put sudden stress on the AC joint Previous shoulder injuries or laxity that predispose to subluxation

Key Symptoms: Pain localized over the top of the shoulder and across the AC joint Swelling or tenderness in the shoulder area A visible bump or deformity at the top of the shoulder Limited range of motion, especially when lifting the arm or reaching across the body A sensation of instability or shoulder slipping during movement Discomfort that worsens with shoulder activity and improves with rest

Diagnosis Path: Diagnosis involves a clinical examination where a healthcare provider assesses shoulder stability, tenderness, and deformity. Imaging tests such as X-rays are used to confirm the subluxation, visualize the extent of displacement, and rule out associated injuries like fractures or full dislocations. Occasionally, MRI may be utilized to evaluate soft tissue damage, such as torn ligaments.

Treatment Protocols: Management focuses on restoring shoulder stability, reducing pain, and preventing recurrence. Treatment options include: - Rest and activity modification to prevent further injury - Application of ice packs to reduce swelling and inflammation - Use of pain relievers or anti-inflammatory medications as advised by a healthcare professional - Physical therapy exercises to strengthen shoulder muscles and improve joint stability - Supportive devices, such as shoulder slings, to immobilize the joint temporarily - In some cases, especially if instability persists or if there are associated injuries, surgical intervention may be necessary to repair damaged ligaments or stabilize the joint. Recovery times vary depending on the severity of the injury and adherence to rehabilitation protocols. Restoring full function typically involves a combination of physical therapy and gradual return to activity.
