Radiographic diagnosis of sagittal plane rotational displacement in pelvic fractures: a cadaveric model and clinical case study.
Our objective was to measure the sagittal plane rotational (flexion and extension) displacement of hemipelvis radiologically and analyze the ratio of flexion and extension displacement of unstable pelvic fractures. ⋯ The sagittal plane rotation (flexion and extension) displacement of pelvic fractures could be measured by special points and lines on the radiographs. Minimally invasive reduction should be based on clearly identified differences between the sagittal plane rotation and the vertical displacement of pelvic fractures.

Review Meta AnalysisAdverse effects associated with the direct anterior approach for total hip arthroplasty: a Bayesian meta-analysis.
The direct anterior approach (DAA) is an increasingly popular technique for performing total hip arthroplasty (THA). This muscle-sparing approach may yield functional benefits. However, DAA has been associated with an increased risk incidence (RI) of intra- and postoperative complications. ⋯ DAA is a technically demanding procedure, with outcomes possibly indicative of surgeon learning curve. A risk for intra-operative fractures and LCFN is evident, although the risk for other adverse effects is comparable to those with other approaches.

Randomized Controlled TrialEffect of irrigation fluid temperature on core body temperature and inflammatory response during arthroscopic shoulder surgery.
This study was designed to evaluate the influence of irrigation fluid on the patients' physiological response to arthroscopic shoulder surgery. ⋯ Hypothermia occurs more often in arthroscopic shoulder surgery by using room temperature irrigation fluid compared with warm irrigation fluid. And local inflammatory response is significantly reduced by using warm irrigation fluid. It seems that warm irrigation fluid is more recommendable for arthroscopic shoulder surgery.

Comparative StudyIsocentric C-arm three-dimensional navigation versus conventional C-arm assisted C1-C2 transarticular screw fixation for atlantoaxial instability.
The Isocentric C-arm 3D navigation has been widely used in superior cervical surgeries in recent years. Several clinical researches reported that navigation system was an effective support device for treatment of atlantoaxial instability. But there were few studies about the advantages of navigation system compared to conventional C-arm fluoroscopy in C1-C2 transarticular screw fixation for atlantoaxial instability. The aim of the study was to evaluate the precision of computer-assisted C1-C2 transarticular screw fixation (Magerl's technique) for atlantoaxial instability and compare the clinical results with conventional C-arm fluoroscopy. ⋯ On comparing the two imaging techniques, it was found that using Iso-C 3D navigation can improve accuracy of the C1-C2 transarticular screws, decrease intra-operative fluoroscopic time and blood loss, and not prolong the operative time. This study demonstrates that Iso-C 3D navigation is a safe and effective means of guiding C1-C2 transarticular screw fixation for atlantoaxial instability.

Quantitative evaluation of residual bony impingement lesions after arthroscopic treatment for isolated pincer-type femoroacetabular impingement using three-dimensional CT.
The objective of this study is to determine the clinical characteristics of residual bony impingement lesions after arthroscopic treatment for pincer-type femoroacetabular impingement (FAI); and to determine the effects of residual bony impingement lesions on the clinical outcomes after 2 years of follow-up. ⋯ The incidence of residual impingement lesions after arthroscopic pincer-type FAI correction was 63.3 %. The residual rate was 14.48 %. The residual impingement lesions were primarily in the posterior portion of the acetabulum. The clinical outcomes were associated with the residual rate of bony impingement lesions. The patients with residual rates >20 % exhibited significantly lower clinical scores and satisfaction rates.
