ASDH in the elderly is a common and increasing problem, and differs in its pathophysiology from ASDH in younger people. Admitting doctors may have difficulty identifying those elderly patients whose lesions may benefit from surgery. The objective of this study was to determine whether simple neuroradiological measurements could identify those patients, who need urgent neurosurgical referral for consideration for surgery. ⋯ Surgically relevant cases of ASDH in the elderly can be reliably and objectively identified by two easily performed scan measurements, haematoma thickness and midline shift. If used in routine practice, these measurements could clarify those patients who may need urgent neurosurgical referral and might avoid unnecessary transfer to neurosurgical units in this cohort.

Bisphosphonates improve implant fixation in randomised clinical trials of knee prostheses, hip prostheses and dental implants. However, a limited amount of bone resorption is required for bisphosphonates to exert an effect. Anti-RANKL treatment does not have this limitation, and we therefore tested whether if they might be more effective for improvement of implant fixation. ⋯ Our results suggest that screw fixation in cancellous bone can be dramatically improved by an anti-RANKL agent. The effect was comparable to very high bisphosphonate doses. Screw insertion in cancellous bone elicits a metaphyseal fracture healing response, and our findings might be relevant not only for implant fixation, but also for fracture healing in cancellous bone.

Comparative Study
Not all intestinal traumatic injuries are the same: A comparison of surgically treated blunt vs. penetrating injuries.
Traumatic intestinal injuries are less common with blunt compared to penetrating mechanisms of trauma and blunt injuries are often associated with diagnostic delays. The purpose of this study is to evaluate differences in the characteristics and outcomes between blunt and penetrating intestinal injuries to facilitate insight into optimal recognition and management. ⋯ Blunt and penetrating intestinal injury patterns have high injury severity. Significant operative delays occurred in the blunt injury group as well as, anastomotic failures, enteric fistulas, nosocomial infections, and higher cost. These features underscore the complexity of blunt injury patterns and warrant vigilant injury recognition to improve outcomes.

Ankle fractures are common injuries treated routinely by orthopaedic surgeons. A variety of different post-operative protocols have been described with differing periods of non-weight bearing after surgery. The aim of this study was to identify how patient injury characteristics and medical comorbidities contribute to the period of non-weight bearing chosen by orthopaedic surgeons after open reduction and internal fixation of rotational ankle fractures. ⋯ Therapeutic Level V.

The goal of this study was to evaluate the performance of haemothorax quantification to predict an abundant transfusion in blunt thoracic trauma patients. ⋯ Retrospective review, level III.
