The treatment of open femur fractures with reimplantation of large extruded segments remains one of the most difficult clinical management scenarios. The situation is even complicated when the extruded segments contains a large osteoarticular segment and no consensus exist about the efficient sterilization. We successfully managed five cases of open femur fracture by reimplantation of a large osteoarticular segment. While the outcomes were favourable, we performed an in vitro investigation in a rat model to determine whether the bone segment preparation strategy was optimal. ⋯ Our study suggests that reimplantation of extruded osteoarticular segments of long bone may represent a feasible alternative to amputation. This is the first description of such a technique and its long-term outcomes in the clinical setting, which were corroborated with the outcomes of in vitro investigation in a rat model, concluding that contaminated extruded osteoarticular segments can be adequately sterilized for reimplantation by cleaning with povidone-iodine scrub followed by brief soaking in antibiotic solution. However, it remains unclear whether the antibacterial efficacy of different sterilizations noted in vitro is reflected in vivo, warranting further research.

Comparative Study
Reduced survival for uncemented compared to cemented total hip arthroplasty after operatively treated acetabular fractures.
Post traumatic arthritis and avascular necrosis of the femoral head are common complications after operatively treated acetabular fractures. This may cause severe disabilities for the patient, necessitating a total hip arthroplasty. Even though an arthroplasty may provide good symptomatic relief, the long-term results are more uncertain and no consensus exists according to preferred prosthetic designs. With this cohort study, we aimed to investigate the medium to long term arthroplasty survival and clinical results of total hip arthroplasty after operatively treated acetabular fractures. ⋯ Total hip arthroplasty secondary to an operatively treated acetabular fracture provides good symptomatic relief. These patients are, however, complex cases and are probably best treated at specialist centres with both pelvic trauma surgeons and arthroplasty surgeons proficient in complex revisions present.

Workers in first responder (FR) occupations are at heightened risk for workplace injury given their exposure to physical/psychological hazards. This study sought to (1) characterise the occupational risk of injury; (2) determine factors associated with injury; and (3) characterise the burden of injury-related disability in police, ambulance officers, fire/emergency workers, compared with other occupations. ⋯ First responders record significantly higher rates of occupational injury claims than other occupations. Using a national population based dataset, this study demonstrates that not only are first responders exposed to significantly higher rates of occupational injury than all other occupations combined, but they experience differential injury patterns depending on their occupation. This suggests that among FR occupations injury prevention efforts should reflect these differences and be targeted to occupation-specific patterns of injury.

Open injuries in children are rare compared to adults. In children with major open injuries, there is no specific scoring system to guide when to amputate or salvage the limb. The use of available adult scoring systems may lead to errors in management. The role of Ganga Hospital Open Injury Severity Scoring (GHOISS) for open injuries in adults is well established and its applicability for pediatric open injuries has not been studied. This study was done to analyse the usefulness of GHOISS in pediatric open injuries and to compare it with MESS(Mangled Extremity Severity Score). ⋯ GHOISS is a reliable predictor of injury severity in type IIIB open fractures in children and can be used as a guide for decision-making. The use of MESS score in children has a lower predictive value compared to GHOISS in deciding amputation versus salvage. A GHOISS of 17 or more has the highest sensitivity and specificity to predict amputation.

Observational Study
Predictors of falls in recreational snowboard jumping: An observational study.
Jumping is popular in the sport of snowboarding. Epidemiological research has shown an increased risk of injury associated with this activity. Falls are common when jumping and although there is a logical connection between falling and injury occurrence, thus far little attention has been given to factors involved in the jumping-fall relationship. The current study aimed to add to the current knowledge base by identifying predictors of falling during intentional snowboard jumping within terrain park facilities. ⋯ It is likely that jumping will remain popular in snowboarding and thus research efforts should focus on minimising the risk of injury associated with this skill. Reducing the overall incidence of falling, identified in the current study to be high, is a potential area for improvement. The potential for fall risk reduction through technique and decision making changes provides justification for further research in this area.
