The Cephalomedullary Nail (CMN) (Zimmer, Warsaw) was introduced in 2010 as part of a multicenter trial to evaluate its performance. At one year the CMN had results in keeping with other intramedullary devices with good union rates and low complication rates. In the second and third years of use an increased rate of implant failure was observed, towards the higher end of the 1-5% nail breakage rate seen in other studies. This study aims to evaluate if there any common features in this cohort of patients. ⋯ Implant failure is a recognised complication of intramedullary nailing in cases of non-union. The increased rate of implant failure in our department required a change to a 130° CMN implant and a 3.2mm diameter guide wire for placement of the lag screw. We continue to monitor this difficult group of patients very closely.

Multicenter Study
The correlation between stabbing-related upper extremity wounds and survival of stabbing victims with abdominal and thoracic injuries.
When treating patients with stab injuries of the torso, clinicians often lack timely information about the degree and nature of internal organ damage. An externally observable sign significantly associated with characteristics of torso injuries may therefore be useful for practitioners. One such potential sign is the presence of wounds to the hands, sometimes sustained during victims' attempt to defend themselves during the violent altercation. Thus, the primary aim of this study was to evaluate the association between presence of upper extremity wounds and the severity of the thoracic and intra-abdominal injuries due to stabbing. ⋯ Patients with stabbing-related upper extremity wounds had a significant survival advantage over patients without such injuries. However, a greater number of sustained upper extremity wounds may be an external sign of greater severity of thoracic and intraabdominal stabbing injuries.

Comparative Study
Simultaneous head and facial computed tomography scans for assessing facial fractures in patients with traumatic brain injury.
Patients with traumatic brain injury (TBI) may have concomitant facial fractures. While most head injury patients receive head computed tomography (CT) scans for initial evaluation, the objective of our study was to investigate the value of simultaneous facial CT scans in assessing facial fractures in patients with TBI. ⋯ TBI patients with risk factors may have a higher probability of concomitant facial fractures. Fractures of the lower third of the face and orbit are easily overlooked in routine head CT scans but often require surgical intervention. Therefore, simultaneous head and facial CT scans are suggested in selected TBI patients.

Injury is a significant cause of death, with approximately 4.7 million people mortalities each year. By 2030, injury is predicted to be among the top 20 causes of death worldwide. We sought to characterize and compare the mortality probability in trauma patients in a resource-poor setting based on anatomic location of injury. ⋯ In our setting, head or spine injury significantly increases the hazard of mortality significantly compared to all other anatomic injury locations. The prioritization of timely operative and non-operative head injury management is imperative. The development of head injury units may help attenuate trauma- related mortality in resource poor settings.

Comparative Study
Does restoration of leg length and femoral offset play a role in functional outcome one year after hip hemiarthroplasty?
The objective of this study was to evaluate the correlation between specific joint biomechanical parameters and 1year functional outcome scores in elderly patients receiving hemiarthroplasty in the setting of intracapsular hip fractures. ⋯ Our study was unable to demonstrate a significant relationship between leg length or femoral offset restoration and the patient's ultimate functional recovery. Arthroplasty surgeons performed better in restoring leg length, but no associated functional advantage was seen.
