Fractures of the proximal femur at the level of the lesser trochanter (reversed and transverse fracture lines, Evans classification type II, AO classification A3 fractures) are known to have an increased risk of fixation failure. 58 patients with such a fracture were randomised to have the fracture fixed with either an intramedullary nail (220 mm Targon PF nail) or a sliding hip screw (SHS). The mean age of the patients was 82 and 11% were male. All patients were followed up for one year by a research nurse blinded to the treatment groups. Mean length of surgery was 50 minutes for the nail versus 52 minutes for the SHS. There were no differences between groups in the need for blood transfusion. Operative complications tended to be less for the nail group (1/27 versus 5/26). Mean hospital stay was 18 days for the nail group versus 29 days for those treated with the SHS. The only fracture healing complications were one case of cut-out in the SHS group and two cut-outs in the nail group, two of which required revision surgery. During follow-up those patients treated with the nail reported a tendency to lower pain scores than those treated with the SHS (p=0.04 at two months). This difference persisted even at one year from injury. Mortality and regain of mobility was similar between groups. These results indicate that for these difficult fractures types both types of fixation produce comparable outcomes

Introduction. The original Charnley-type negative pressure body exhaust suit reduced infection rates in randomized trials of total joint arthroplasty decades ago. Modern positive pressure surgical helmet systems (SHS) have not shown similar benefit, and several recent studies have shown a trend towards increased wound contamination and infection with SHS use. The gown glove interface may be one source of particle contamination. Objectives. The purpose of this study was to compare particle contamination at the gown glove interface in several modern SHS vs. a conventional gown. Methods. A 0.5 micron fluorescent powder was evenly applied to both hands to the level of the wrist flexion crease. After gowning in the normal fashion, the acting surgeon performed a standardized twenty minute simulated total joint replacement. The amount of gown contamination at the gown glove interface was then measured by three observers under ultraviolet light using a standardized grading scale; from 0 (no contamination) to 4 (gross contamination). Using Minitab 15, the Mann-Whitney U test was performed to compare gowns and an ordinal logistic regression analysis was performed to identify variables associated with levels of contamination. Results. All gown-glove interfaces showed some contamination. There was no difference among any of the gowns except for gown 2, which showed significantly more contamination when compared directly to each of the other four gowns (p<0.001 in each case) (Figure 1). The ordinal logistic regression analysis showed that gown type (p 0.10) was more significantly associated with contamination levels than were the other variables of observer (p 0.70), location of contamination (p 0.56), or trial order (p 0.5). Conclusions. Particle contamination occurs at the gown glove interface in most commonly used surgical helmet systems and was significantly increased in the gown with stiffer material that may be less apt to make a seal with the glove

It is unusual, if not unique, for three major research papers concerned with the management of the fractured neck of femur (FNOF) to be published in a short period of time, each describing large prospective randomized clinical trials. These studies were conducted in up to 17 countries worldwide, involving up to 80 surgical centers and include large numbers of patients (up to 2,900) with FNOF. Each article investigated common clinical dilemmas; the first paper comparing total hip arthroplasty versus hemiarthroplasty for FNOF, the second as to whether ‘fast track’ care offers improved clinical outcomes and the third, compares sliding hip with multiple cancellous hip screws. Each paper has been deemed of sufficient quality and importance to warrant publication in The Lancet or the New England Journal of Medicine. Although ‘premier’ journals, they only occationally contain orthopaedic studies and thus may not be routinely read by the busy orthopaedic/surgical clinician of any grade. It is therefore our intention with this present article to accurately summarize and combine the results of all three papers, presenting, in our opinion, the most important clinically relevant facts.
