Insights
An infant
Area of Science:
- Pediatric Orthopedics
- Neurology
- Biomechanical Analysis
Background:
- Shoulder dislocations in infants are rare.
- Previous cases involved congenital anomalies, Erb's palsy, or septic arthritis.
- This case presents a unique association with spastic brain damage.
Observation:
- A 7 1/2-month-old boy presented with an anterior inferior shoulder dislocation.
- The infant had significant spastic brain damage.
- Deltoid muscle spasticity was hypothesized as the deforming force.
Findings:
- Surgical intervention included capsular and subscapularis plication with deltoid muscle recession.
- The procedure successfully corrected the shoulder dislocation.
- Recurrence of dislocation was prevented post-surgery.
Implications:
- This case highlights spastic brain damage as a potential cause of infantile shoulder dislocation.
- Surgical management involving plication and recession can effectively treat this condition.
- Understanding the biomechanical impact of muscle spasticity is crucial in pediatric orthopedic cases.
Abstract:
A 7 1/2-month-old boy had an anterior inferior dislocation of the shoulder. Dislocations of the shoulder in infants have previously been reported, and were either congenital dislocations with associated anomalies of the glenohumeral joint with dislocations from Erb's palsy or septic arthritis. In the present case, dislocation of the shoulder was associated with spastic brain damage. The marked spasticity of the deltoid muscle may have been the deforming force. Capsular and subscapularis plication plus recession of the deltoid corrected the deformity and prevented further dislocations.
