The impact of resident involvement on post-operative morbidity and mortality following orthopaedic procedures: a study of 43,343 cases.
Few studies have addressed the role of residents' participation in morbidity and mortality after orthopaedic surgery. The present study utilized the 2005-2010 National Surgical Quality Improvement Program (NSQIP) dataset to assess the risk of 30-day post-operative complications and mortality associated with resident participation in orthopaedic procedures. ⋯ II (Prognostic).

All arthroscopic release of the glenohumeral joint for severe frozen shoulder: initial glenohumeral visualization through trans-cuff portal.
In recent two decades, a novel minimally invasive technique for resistant frozen shoulder, arthroscopic glenohumeral release, has been popularly practiced. However, by far one key point, although being well recognized, has not been tackled at all during the procedure-that is how to safely and smoothly insert the arthroscope into contracted and restricted glenohumeral joint when MUA cannot be performed or work, especially the severe stiff shoulder. ⋯ Level IV, Case Series, Treatment Study.

Cardiovascular effects of abduction shoulder sling in elderly patients; is it really safe?
The purpose of the prospective study is to investigate the cardiovascular effects of abduction shoulder sling (ASS) in elderly patients who underwent rotator cuff surgery. ⋯ ASS may trigger CSH in short necked and obese patients by exerting mechanical stimulation to the carotid sinus. These patients should be informed about symptoms and signs of CSH and educated on the proper use of ASS and correct positioning of shoulder strap. CSH should be kept in mind in patients who present with dizziness, presyncope and palpitation during the postoperative period.

Impact of spinal imbalance and BMI on lumbar spinal canal stenosis determined by a diagnostic support tool: cohort study in community‑living people.
The Japanese Society for Spine Surgery and Related Research (JSSR) developed a diagnostic support tool (score range −2 to 16) for lumbar spinal canal stenosis (LSS). It is well known that patients with LSS have a forward-bending posture while walking. We could find only one study which examined sagittal alignment of LSS patients. The objectives of this study were to screen community-living people with LSS, and to investigate the association between LSS and spinal sagittal alignment, range of motion (ROM), and other spinal or physical factors. ⋯ Increased SIA and BMI might be the most relevant risk factors for LSS.

Biomechanical evaluation of the primary stability of pedicle screws after augmentation with an innovative bone stabilizing system.
In today's aging population, diminished bone quality often affects the outcome of surgical treatment. This occurs especially when surgical implants must be fixed to bone, as it occurs when lumbar fusion is performed with pedicle screws. Besides Polymethylmethacrylate (PMMA) injection, several techniques have been developed to augment pedicle screws. The aim of the current study was to evaluate the primary stability of an innovative system (IlluminOss™) for the augmentation of pedicle screws in an experimental cadaveric setup. IlluminOss™ is an innovative technology featuring cement with similar biochemical characteristics to aluminum-free glass-polyalkenoate cement (GPC). ⋯ Based on these data, we conclude the IlluminOss™ system can be used to augment primary screw stability regarding axial traction, compared to native screws. The IlluminOss™ monomer offers ease of control for use in biological tissues. In contrast to PMMA, no relevant heat is generated during the hardening process and there is no risk of embolism. Further studies are necessary to evaluate the usefulness of the IlluminOss™ system in the in vivo augmentation of pedicle screws in the future.
