A child
Area of Science:
- Pediatric Orthopedics
- Muscle Physiology
Background:
- Deltoid muscle contracture is a rare condition affecting shoulder abduction.
- Previous cases involved fibrous cords or nodules within the deltoid muscle.
Observation:
- A child presented with left shoulder abduction contracture due to diffuse deltoid muscle fibrosis.
- The contracture's etiology was potentially linked to birth brachial plexus injury or idiopathic fibrosis.
Findings:
- Successful treatment was achieved through proximal recession of the deltoid muscle's inserting fibers.
- This surgical approach addressed the diffuse fibrosis, unlike prior methods targeting localized lesions.
Implications:
- Proximal recession offers a viable surgical option for deltoid contractures caused by diffuse fibrosis.
- Further research is needed to clarify the pathogenesis of this specific type of deltoid fibrosis.
Abstract:
A child with an abduction contracture of the left shoulder secondary to diffuse fibrosis of the deltoid muscle was successfully treated by recession of the inserting muscle fibers proximally. Previously reported cases of deltoid muscle contracture were secondary to fibrous cords or nodules within the muscle. This patient's contracture may be related to either a brachial plexus birth injury or may be similar to the idiopathic fibrosis seen in the quadriceps muscle.
