Satisfactory Outcome

Coracoid fractures are uncommon, mostly occur at the base or neck of the coracoid process (CP), and typically present with ipsilateral acromioclavicular joint (ACJ) dislocation. However, CP avulsion fractures at the coracoclavicular ligament (CCL) attachment with ACJ dislocation have not been previously reported. A 59-year-old woman receiving glucocorticoid treatment fell from bed and complained of pain in her shoulder. Radiographs revealed an ACJ dislocation with a distal clavicle fracture. Three-dimensional computed tomography (3D-CT) reconstruction showed a small bone fragment at the medial apex of the CP. She was treated conservatively and achieved a satisfactory outcome. CP avulsion fractures at the CCL attachment can occur in osteoporotic patients with ACJ dislocations. Three-dimensional computed tomography is useful for identifying this fracture type. CP avulsion fractures should be suspected in patients with ACJ dislocations and risk factors for osteoporosis or osteopenia.

Avulsion fracture at the site of attachment of the coracoid process of the coracoclavicular ligament (CCL) is extremely rare. We presented three adult cases of this unusual avulsion fracture associated with other injuries. Case  1 was a 25-year-old right-handed male with a left distal clavicular fracture with an avulsion fracture of the coracoid attachment of the CCL; this case was treated surgically and achieved an excellent outcome. Case  2 was a 39-year-old right-handed male with dislocation of the left acromioclavicular joint with two avulsion fractures: one at the posteromedial surface of the coracoid process at the attachment of the conoid ligament and one at the inferior surface of the clavicle at the attachment site of the trapezoid ligament; this case was treated conservatively, and unfavorable symptoms such as dull pain at rest and sharp pain during some daily activities remained. Case  3 was a 41-year-old right-handed female with a right distal clavicular fracture with an avulsion fracture of the coracoid attachment of the conoid ligament; this case was treated conservatively, and the distal clavicular fracture became typical nonunion. These three cases corresponded to type I fractures according to Ogawa’s classification as the firm scapuloclavicular connection was destroyed and also to double disruption of the superior shoulder suspensory complex. We recommend surgical intervention when treating patients with this type of acute or subacute injury, especially in those engaging in heavy lifting or overhead work.

Maxillofacial Fractures

ABSTRACTIntroduction: Because of its functional and cosmetic importance, facial injuries, especially bony fractures are clinically very significant. Missed and maltreated fractures might result in malocclusion and disfigurement of the face, thus making accurate diagnosis of the fracture very essential. In earlier times, conventional radiography along with clinical examination played a major role in diagnosis of maxillofacial fractures. However, it was noted that the overlapping nature of bones and the inability to visualise soft tissue swelling and fracture displacement, especially in face, makes radiography less reliable and useful. Computed tomography (CT), also called as X-ray computed radiography, has helped in solving this problem. This clinical study is to compare three-dimensional (3D) CT reconstruction with conventional radiography in evaluating the maxillofacial fractures preoperatively and effecting the surgical management, accordingly. Materials and Methods: Fifty patients, with suspected maxillofacial fractures on clinical examination, were subjected to conventional radiography and CT face with 3D reconstruction. The number and site of fractures in zygoma, maxilla, mandible and nose, detected by both the methods, were enumerated and compared. The final bearing of these additional fractures, on the management protocol, was analysed. Results: CT proved superior to conventional radiography in diagnosing additional number of fractures in zygoma, maxilla, mandible (subcondylar) and nasal bone. Coronal and axial images were found to be significantly more diagnostic in fracture sites such as zygomaticomaxillary complex, orbital floor, arch, lateral maxillary wall and anterior maxillary wall. Conclusion: 3D images gave an inside out picture of the actual sites of fractures. It acted as mind’s eye for pre-operative planning and intra-operative execution of surgery. Better surgical treatment could be given to 33% of the cases because of better diagnostic ability of CT.

Abstract Purpose This study aimed to assess the biomechanical stability of a novel internal fixation system of EndoButton plate combined with suture anchor in treating acromioclavicular joint dislocation in the cadaveric specimens. In addition, it provides a new method for the clinical treatment of acromioclavicular joint dislocation. Methods Twelve complete shoulder joint specimens were randomly divided into groups A, B, C, and D (n = 3). Firstly, a quasi-static non-destructive circulation experiment was carried out of coracoclavicular ligament until its function failed. Four different internal fixation materials were used to reduce and fix the acromioclavicular joint. Group A was treated with 3.5 mm clavicular hook locking compression plates, Group B with 5 mm suture anchor Group C with 10 mm Endo-button plate, and Group D with a novel combination of 5 mm suture anchor and 10 mm Endo-button plate. Fluoroscopy was performed to undertake the X-ray of the restored acromioclavicular joint, to evaluate the internal fixation position and acromioclavicular joint reduction. Finally, the shoulder joint was fixed firmly on an electronic universal testing machine (100KN) with a self-made stationary fixture, to conduct a destructive static tensile mechanical test of each specimen vertically at a 100 mm/min load speed. The stress-deformation curve was recorded using a computer connected with the universal mechanical testing machine, and the failure strength and reasons for internal fixation were also recorded. Results The average load-to-failure of the coracoclavicular ligament in groups A, B, C, and D was 373.4 ±0.57 N, 373.6 ±0.62 N, 374.4 ±0.68 N, and 373.9 ±0.15 N, respectively (P>0.05). After internal fixation failure, Group A showed two specimens with clavicular fracture, and one with acromial fracture, with an average load-to-failure of 409.8 ±2.92 N. Group B and D showed three specimens with prolapse of anchor, with average load-to-failure of 293.5 ±4.10 N and 374.2 ±0.40 N, respectively. Group C showed three specimens with basilar coracoid fracture, with average load-to-failure of 373.2 ±2.35 N. Statistical differences existed in the biomechanical load of internal fixation failure among the four groups. Group D was statistically different from Group A and Group B, but not Group C. Conclusion The newly designed EndoButton plate combined with suture anchor for coracoclavicular ligament reconstruction was found to boast simple operation and has high feasibility. Thus it was found effective in the reduction of acromioclavicular joint and treatment of acromioclavicular joint dislocation and fitted the biomechanical characteristics of the acromioclavicular joint.
