“…Almost half of the reported cases have been treated conservatively and result in good and excellent outcome [ 2 , 3 , 7 , 9 , 10 , 13 – 15 , 17 , 21 , 26 , 29 ]. According to our literature review, it is hard to suggest best treatment option.…”

“…Epiphyseal separation of the CP is usually diagnosed by obtaining plain shoulder radiographs consisting of three views. Special radiograms are required in order to make a definitive diagnosis: 30° cephalad roentgenogram [ 7 ], 45° to 60° cephalad tilt [ 31 ], or abduction view that clearly scans the CP without overlapping other bone structures [ 9 , 16 ]. However, CT, especially three-dimensional CT, and magnetic resonance imaging are usually necessary because of the limitations of plain radiography [ 1 , 14 , 18 ].…”

Objectives and Design. Epiphyseal separation of the coracoid process (CP) rarely occurs in adolescents. In this retrospective case series, we reviewed the data of nine patients treated at our center and those of 28 patients reported in the literature. This injury can be classified into three types according to the injured area: Type I, base including the area above the glenoid; Type II, center including the coracoclavicular ligament (CCL); and Type III, tip with the short head of the biceps and coracobrachialis, as well as the pectoralis minor. Patients/Participants. A total of 37 patients were included in the analysis. Data on sex, age, cause and mechanism of injury, separation type, concomitant injury around the shoulder girdle, treatment, and functional outcomes were obtained. Main Outcome Measurements and Results. Type I is the most common type. The cause of injury and associated injury around the shoulder girdle were significantly different between Type I, II, and III fractures. The associated acromioclavicular (AC) dislocation and treatment were significantly different between Type I and III fractures. Our new classification system reflects the clinical features, imaging findings, and surgical management of epiphyseal separation of the CP. Type I and II fractures are mostly associated with AC dislocation and have an associated injury around the shoulder girdle. Type III fractures are typically caused by forceful resisted flexion of the arm and elbow. Although the latter are best managed surgically, whether conservative or surgical management is optimal for Type I and II fractures remains controversial. Conclusions. We noted some differences in the clinical characteristics depending on the location of injury; therefore, we aimed to examine these differences to develop a new system for classifying epiphyseal separation of the CP. This would increase the clinicians’ awareness regarding this injury and lead to the development of an appropriate treatment.

“…On the other hand, all reported patients treated surgically recovered fully, except for one reported by Wilber and Evans, who was treated with an unknown surgical method and reported of persistent pain and decreased shoulder motion 1 year postoperatively. 13 Multiple approaches have been opted for by surgeons to deal with this combined injury; some have opted to address only the AC joint and others have found that surgical reduction of the CP reduced the AC indirectly 9–13. Nevertheless, disrupted CC ligaments should always be repaired or reconstructed for optimal functional outcome whenever associated with these combined injuries 3.…”

SUMMARYAvulsion fracture of coracoid process with acromioclavicular joint dislocation is extremely rare. We report a case of coracoid avulsion with acromioclavicular disruption in a 24-year-old man who sustained injuries in a road traffic accident. Although acromioclavicular (AC) dislocation was obvious from an initial radiograph, coracoid avulsion was picked up in a CT scan. Open reduction and internal fixations of the coracoid with a 4 mm cannulated screw, an AC joint with two K-wires and an anchor suture, resulted in rapid recovery. The patient had complete range of shoulder movements at the end of 3 months and he resumed his professional activities. After 1 year, he had normal shoulder movement without any functional limitations. BACKGROUND
