Ipsilateral simultaneous fracture of the trochlea involving the lateral end clavicle and distal end radius: a rare combination and a unique mechanism of injury / 中华创伤杂志(英文版)

Isolated trochlea fracture in adults is a rare surgical entity as compared to its capitellar counterpart. It has been only mentioned sporadically in the literature as case reports. Fracture of the trochlea is accompanied by other elbow injuries like elbow dislocation, capitellum fracture, ulnar fracture and extraarticular condylar fracture. Here we report a unique case of isolated displaced trochlea fracture associated with fractures of the lateral end clavicle and the distal end radius. We propose a unique mechanism for this rare combination of injuries: typical triad of injury, i.e. fracture of the distal end radius with trochlea and fracture of the lateral end of the clavicle. Nonoperative treatment is recommended for undisplaced humeral trochlea fractures; but for displaced ones, anatomical reduction and internal fixation are essential to maintain the congruous trochlea-coronoid articulation and hence to maintain the intrinsic stability of the elbow.

Double floating arm injury in a child: a case report and review of the literature / 中华创伤杂志(英文版)

The combination of ipsilateral humeral fractures at three different levels namely proximal, shaft and supracondyle has been rarely defined in the literature. We present a case report on such a complex injury in a 10-year-old child after falling down from the second floor of his house while playing. To the best of our knowledge, no such case report exists in the English literature. We define it as double floating arm injury. Firstly, shaft of humerus was open reduced and fixed with 4.5 mm narrow dynamic compression plate. Then closed reduction and pinning of the supracondylar humerus under an image intensifier was obtained. Open reduction using deltopectoral approach to the proximal humerus was done and the fracture was fixed with three K-wires. Ipsilateral multiple fractures in children often result from high energy trauma. Immediate reduction and fixation is required. Usually surgeons need to treat simple fractures firstly, which makes the subsequent treatment of complex fractures easier.

Simultaneous bilateral trochanteric fractures---a report of four cases / 中华创伤杂志(英文版)

Simultaneous bilateral intertrochanteric fractures are very rare. There is a paucity of data in current literature documenting patients with such kind of hip fractures. It is severe and potentially life-threatening, associated with a high morbidity. The major determinants of successful outcome are high vigilance, early single stage stabilization and mobilization as well as management of associated comorbid conditions that may influence the long term rehabilitation of patients. Here we reported 4 cases of concurrent bilateral trochanteric fractures along with review of the literature. Our study aimed to discover its frequency, identify the injury mechanisms as well as factors present in the pathogenesis of these fractures, and outline the available treatment modalities.
