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.
