Comparative Study
Trauma-related amputations in war and at a civilian major trauma centre-comparison of care, outcome and the challenges ahead.
The Afghanistan conflict has resulted in a large number of service personnel sustaining amputations. Whilst obvious differences exist between military and civilian trauma-related amputations both settings result in life changing injuries. Comparisons offer the potential of advancement and protection of the knowledge gained during the last 12 years. ⋯ Rehabilitation outcome measures recorded included the Special Interest Group in Amputee Medicine score where the military group demonstrated significantly better scores (91% Grade E+ compared to 19%). Differences in patients underlying physiology and psychology, the military trauma system and a huge sustained investment in rehabilitation are all contributing factors for these differing outcomes. However the authors also believe that the use of a consultant-led MDT and central rehabilitation have benefited the military cohort in the acute rehabilitation stage and is reflected in the good short-term outcomes.

Multicenter Study
Geriatric distal femur fracture: Are we underestimating the rate of local and systemic complications?
Low energy distal femur fractures often occur in a fragile elderly population that is prone to local and systemic complications following operative treatment of extremity fractures. The nonunion rate and early complication rate following laterally based locked plating in this specific fracture are not well described. ⋯ Level III prognostic.

Both plate and intramedullary nail fixations, including straight and anatomic nails, have been clinically adopted for the treatment of displaced mid-shaft clavicle fractures. However, the biomechanical performances of these fixations and implants have not been well evaluated. This study aims to compare the construct stability, stress distribution and fracture micro-motion of three fixations based on finite element (FE) method. ⋯ The plate fixation significantly stabilizes the fracture gap, reduces the implant stress, and serves as the recommended fixation for the mid-shaft clavicle fracture. The CRx is an alternative device to treat clavicle shaft fracture, but the shoulder excessive activities should be avoided after operation.

Femoral reaming using a Reamer Irrigator Aspirator (RIA) can produce greater than three liters of waste water per procedure, which contains cells and proteins that could promote bone healing. This purpose of this study was to determine the protein profile of RIA waste water and compare protein synthesis by cells harvested via RIA versus iliac crest (IC) bone graft. ⋯ RIA waste water has potential to serve as an autogenic and allogenic enhancer for bone healing. Continued development of processing protocols for viable commercial use of the waste water and pre-clinical studies designed to evaluate RIA waste water products for bone healing are ongoing.

Randomized Controlled Trial Comparative Study
Comparison of clinical and radiologic outcomes between non-operative and operative treatment in 5th metatarsal base fractures (Zone 1).
The treatment of Zone 1 fractures of the 5th metatarsal base with >2mm of displacement remains controversial. We prospectively analyzed 29 patients with 5th metatarsal base fractures (Zone 1) during 2009-2014. Radiography was performed to assess the degree of fracture gap and metatarsal length. ⋯ Visual analog scale (VAS) score and American orthopedic foot and ankle society (AOFAS) score were obtained at the initial consult and at the last follow-up after treatment; change of the 5th metatarsal length was also measured at the initial consult and after complete bony union. Our study demonstrated that radiographic union of all cases was observed with a significant decrease in VAS and AOFAS scores, regardless of the initial fracture gap and type of management. Additionally, there was no difference seen in final VAS scores for patients with longer metatarsals when compared to those in whom the metatarsals were unchanged or shortened.
