Summary
This study describes a rare bilateral pectoral muscle disorder in an 11-year-old boy. Surgical lengthening of the chondroepitrochlearis muscle resulted in significant cosmetic and functional improvements.
Area of Science:
- Orthopedics
- Human Anatomy
- Rare Musculoskeletal Disorders
Background:
- The chondroepitrochlearis muscle is an anomalous musculotendinous unit originating from the pectoralis major and inserting onto the medial epicondyle of the humerus.
- This muscle variant is extremely rare and can affect pectoral region function and aesthetics.
Observation:
- A case study of an 11-year-old boy presenting with bilateral chondroepitrochlearis muscle anomalies is detailed.
- The patient exhibited functional and cosmetic concerns related to the bilateral muscle involvement.
Findings:
- Surgical intervention involving lengthening of the anomalous chondroepitrochlearis muscle was performed.
- The surgical treatment led to substantial improvements in both the cosmetic appearance and functional capacity of the affected pectoral region.
Implications:
- This case highlights the importance of recognizing and surgically addressing rare muscle anomalies for improved patient outcomes.
- Lengthening the chondroepitrochlearis muscle can be an effective treatment for associated functional and cosmetic deficits.
- Further research into rare pectoral muscle variations and their surgical management is warranted.
