Detecting cam-type deformities on plain radiographs: what is the optimal lateral view?
Radial magnetic resonance imaging (MRI) is the most accurate diagnostic tool in assessing cam-type femoroacetabular impingement. Plain radiographs, however, are useful for the initial diagnosis in the daily practice and there is still debate regarding the optimal lateral view. The purpose of this study was to investigate the reliability of detecting cam deformities using the frog-leg view or the 45° Dunn view by comparison with radial MRI. ⋯ The frog-leg lateral radiograph does not provide reliable measurements of the alpha angle. This study highlights the importance of the 45° Dunn view for early detection of femoroacetabular cam-type impingement.

Meta AnalysisAccuracy of a patient-specific template for pedicle screw placement compared with a conventional method: a meta-analysis.
Accurate placement of pedicle screws in spine surgery is a challenge for surgeons. Patient-specific template techniques have the potential for improving the accuracy of screw placement. The target of this analysis was to investigate differences in terms of accuracy of pedicle screw insertion between patient-specific template assistance and the conventional free-hand method for reconstruction of spinal stability. ⋯ The template-assisted technique is superior to the conventional method for the reduction of pedicle violation. The template-assisted technique is a promising technique that should be considered as another available navigation tool for surgeons to improve the accuracy of pedicle screw placement. As an available technique for emerging applications in spine surgeries, this technique will face challenges but ultimately prove successfully.

Comparative StudyNo difference in outcome for open versus arthroscopic rotator cuff repair: a prospective comparative trial.
Arthroscopic techniques tend to become the gold standard in rotator cuff repair. However, little data are reported in the literature regarding the improvement of postoperative outcomes and re-tear rate relative to conventional open surgery. The aim of this study was to compare clinical outcomes and cuff integrity after arthroscopic versus open cuff repair. ⋯ Prospective comparative study.

Pain catastrophizing as a predictor for postoperative pain and opiate consumption in total joint arthroplasty patients.
Pain catastrophizing has been suggested as a prospective risk factor for poor postoperative pain outcomes in total joint arthroplasty (TJA). However, results from the previous studies have been mixed and have not controlled for postoperative opiate analgesic intake. This study investigates pain catastrophizing and postoperative pain intensity in TJA patients, adjusting for analgesic intake. We hypothesized that "pain catastrophizers" would exhibit higher pain scores and increased analgesic requirements postoperatively. ⋯ The pain catastrophizing scale is a poor predictor of postoperative pain at 3-month follow-up. However, it may be a risk factor for increased LOS.
