This study summarizes orthopedic injuries sustained in motorcycle collisions in patients presenting to a Level I trauma center. ⋯ Motorcycle collisions frequently involve patients in their working prime, thus placing substantial burden on the individual and society. Although these patients must continue to receive Level I trauma care, strengthened prevention and improved education efforts are warranted.

Plate osteosynthesis of the scaphoid, as reported earlier by Ender, has lost its importance in the past few years, after Herbert's introduction of the simple and successful technique of screw osteosynthesis. Only in rare cases does one encounter failed healing or instability of the fragments. Even with a vascularized bone chip, it is not always possible to achieve consolidation. Particularly in these situations, poor interfragmentary stability seems to be the reason for failed healing. ⋯ Scaphoid plate osteosynthesis should be regarded as a salvage procedure, and the indication for the procedure should be established accordingly. It is a simple procedure in terms of technique. The plate can be adjusted very well to the anatomic shape of the scaphoid, and one can achieve a high degree of stability, particularly rotational stability.

Our objective is to evaluate the mortality and outcomes of hemodynamically unstable patients with pelvic fractures treated with a protocol that directs the patient to either early pelvic angiography or early retroperitoneal pelvic packing. ⋯ Early experience in our institution suggests that early pelvic packing with subsequent angiography if needed is as good as angiography with embolization in treating patients with hemodynamically unstable pelvic fractures.

There is evidence that complement components regulate cytokine production in osteoblastic cells, induce cell migration in mesenchymal stem cells, and play a regulatory role in normal enchondral bone formation. We proved the hypothesis that complement might be involved in bone healing after fracture. ⋯ Our in vitro and in vivo results demonstrated the presence of C5aR in bone forming osteoblasts and bone resorbing osteoclasts. It is suggested that C5aR might play a regulatory role in fracture healing in intramembranous and in enchondral ossification, one possible function being the regulation of cell recruitment.

Traumatic pneumomediastinum secondary to blunt chest injury in children is concerning for potential life-threatening tracheobronchial, esophageal, or vascular thoracic injuries. These patients often undergo extensive radiologic evaluation and invasive testing due to the unclear risk of traumatic pneumomediastinum. ⋯ Tracheobronchial, esophageal, or vascular thoracic injuries were uncommon in children with traumatic pneumomediastinum and occurred in the setting of additional thoracic and other organ system injuries. Pneumomediastinum without radiographic or clinical evidence of other thoracic injuries may not routinely require further diagnostic testing.
