Multicenter Study
Smoking is a risk factor of organ/space surgical site infection in orthopaedic surgery with implant materials.
In recent guidelines, smoking is reported as a factor increasing the risk of surgical site infection (SSI). The accurate analysis of the literature shows that this recommendation relies on low level of evidence in orthopaedic surgery with material implantation (arthroplasty components or implants for internal fixation). This study aimed to assess the attributable risk of smoking on organ/space SSI in orthopaedic surgery with implants. ⋯ This is the first large prospective report of a significant association between smoking and organ/space SSI in orthopaedic surgery with implants.

Multicenter Study
Predictors for moderate to severe acute postoperative pain after total hip and knee replacement.
The ability to identify and focus care to patients at higher risk of moderate to severe postoperative pain should improve analgesia and patient satisfaction, and may affect reimbursement. We undertook this multi-centre cross-sectional study to identify preoperative risk factors for moderate to severe pain after total hip (THR) and knee (TKR) replacement. ⋯ Our findings provide clinical guidance for preoperative stratification of patients for more intensive management potentially including education, nursing staffing, and referral to specialised pain management.

Multicenter Study Clinical Trial
A retrospective study of posterior malleolus fractures.
In this retrospective study, we evaluated the treatment effect of ankle joint fracture surgery involving the posterior malleolus, and discuss relevant factors influencing the occurrence of traumatic arthritis of the ankle joint. ⋯ For all 102 cases of ankle joint fracture involving the posterior malleolus, the treatment effect was satisfactory. Restoration of an even articular surface, especially when fragment size ≥ 25 %, should be attempted during treatment.

The incidence of deep vein thrombosis, non-fatal pulmonary embolism and fatal pulmonary embolism may be as high as 61%, 10% and 2%, respectively, in patients with pelvic and acetabular injuries. A survey of the pelvic and acetabular units across the United Kingdom was performed to ascertain the thrombo-prophylaxis policy for these patients. In particular, questions were asked about different regimes on post-operative patients, conservatively managed patients and those simply discussed over the telephone. We enquired about their known rates of DVT and PE and their methods of data collection. ⋯ Despite high rates of thrombo-embolic complications in patients with pelvic and acetabular injuries there is no UK consensus on prescribing prophylaxis.

Multicenter Study Clinical Trial
Second generation locked plating of proximal humerus fractures--a prospective multicentre observational study.
Surgical treatment of most displaced proximal humerus fractures is challenging due to osteoporosis. Locking plates are intended to provide superior mechanical stability. In a prospective multicentre study 131 patients were treated with second generation locked plating (NCB-PH, Zimmer, Inc.). ⋯ The most frequent complications detected were intra-articular screw perforation (15%) and secondary displacement (8%). Complication rate and functional outcome of the NCB-PH are comparable to reports in the literature. Not all problems are likely to be solved by this new generation of implants, i.e. secondary dislocation still occurred in 8% of our patients.
