Abstract
A case of painful right shoulder in a 39 year old Thai female. She had a painful range of motion due to forward flexion and adduction with no any limit active range of motion for 5 months. The diagnosis was confirmed with incisional biopsy for tissue pathological report. 9-months after treated with arthroscopic coracoclavicular joint resection, she regained a pain-free range of motion.
Highlights
The coracoclavicular joint is an uncommon anatomical variant with a diarthrotic synovial joint between the conoid tubercle of the clavicle and the superior surface of the coracoid process [1]
Arthroscopic resection of the coracoclavicular joint was performed in order to improve her life quality by restore her shoulder motion
The coracoclavicular joint was resected through the anteroinferior portal by arthroscopic burr (Figure 5)
Summary
The coracoclavicular joint is an uncommon anatomical variant with a diarthrotic synovial joint between the conoid tubercle of the clavicle and the superior surface of the coracoid process [1]. By the way the coracoclavicular joint does not usually produce any symptom. The right shoulder examination revealed full active and passive range of motion. The radiographic examination revealed the presence of an accessory joint between the coracoid and the conoid tubercle (Figure 1).
