Abstract

Background: Avulsion fracture of the coracoclavicular ligament accompanied by upward displacement of the medial fragment of the clavicle represents a unique fracture pattern, first described by Latarjet and colleagues in 1975. Due to the function of the underlying articulations and the ligaments found in the area, this fracture pattern results in a combination of horizontal and vertical instability that must be taken into consideration when treating. Several surgical techniques have been proposed but none has been proven superior.

Case summary: Herein, we present a Latarjet fracture of the distal clavicle treated with a single endobutton. A 45-year-old male underwent open surgical stabilization of distal clavicular fracture 15 days after trauma. After stabilization of the fracture, we applied a single endobutton, passing through the medial fragment, inferior fragment and coracoid process. The patient was observed for 14 mo postoperative, during which time he achieved union in all three fragments of the fracture and an excellent functional clinical score.

Conclusion: In Latarjet fracture treatment, augmentation of the coracoclavicular ligament is the most important parameter for a favorable result.

Radiographic history of the fracture in this case. A: Latarjet fracture was diagnosed based upon the finding of an avulsed fracture of the coracoclavicular ligaments and upward displacement of the central fragment of the clavicle; B: Postoperative radiograph confirmed the endobutton passing through the medial fragment, avulsed inferior fragment and coracoid; C: Control radiograph at 18 mo after surgery showed osseous union of the fracture with alignment in acromioclavicular articulation.

Physical and functional outcomes at the end of the 18 mo follow-up period. The patient was pain-free, without restriction of range of motion, and no difference in strength compared to the contralateral arm. The constant shoulder score of the right shoulder was 100.
