Background: Patient satisfaction is used as an indicator of quality of care, but the measures currently available are lengthy and cumbersome and may not be feasible in orthopedic surgical practices. We set out to assess the relationship between the Medical Interview Satisfaction Scale (MISS-21) and a numerical rating scale (NRS) of patient satisfaction with current management of an orthopedic upper extremity condition. Methods: In this cross-sectional study, 86 patients from the practices of 2 hand surgeons were included during an initial or follow-up visit...

OBJECTIVES: Implant placement immediately after tooth extraction is often accompanied by resorption of surrounding tissues. A clinical technique was developed where the buccal portion of the root is retained to preserve the periodontal ligament and bundle bone. This technique is based on animal studies showing the potential to preserve the facial tissues utilizing this approach. The purpose of this study was to gain more insight regarding the safety of the technique with regard to biological and implant-related long-term complications and to observe the clinical appearance of the peri-implant tissues...

PURPOSE: An electromagnetic (EM) surgical tracking system was developed for orthopedic navigation. The reportedly poor accuracy of point-based EM navigation was improved by using anatomical impressions, which were EM-tracked personalized templates. Lines, rather than points, were consistently used for calibration and error evaluation. METHODS: Technical accuracy was tested using models derived from CT scans of ten cadaver shoulders. Tracked impressions were first designed, calibrated, and tested using lines as fiducial objects...

Six cases of dystonic tremor were treated with the Vercise<sup>TM</sup> deep brain stimulation(DBS)system, which has the multiple independent current control(MICC)technology. The mean preoperative score of Burke-Fahn-Marsden dystonia rating scale was 16.2±9.4, which was reduced to 6.1±4.6 at 5 months postoperatively. A 65-year-old male presented an intractable dystonic tremor of the jaw, neck, and shoulders due to tardive syndrome. He experienced the successful tremor relief after unipolar DBS in the globus pallidus internus(GPi)with Vercise<sup>TM</sup> but complained of dysarthria...

BACKGROUND AND OBJECTIVES: Continuous brachial plexus blocks at the interscalene level are associated with known diaphragm dysfunction from phrenic nerve paresis. More distal blocks along the brachial plexus may provide postsurgical analgesia while potentially having less effect on diaphragm function. Continuous interscalene, continuous supraclavicular, and continuous suprascapular nerve blocks were evaluated for respiratory function and analgesia after total shoulder arthroplasty. METHODS: After ethics board approval, subjects presenting for total shoulder arthroplasty were planned for randomization in a 1:1:1 ratio of a continuous interscalene, supraclavicular, or suprascapular block...

Neglected and underestimated in the past, Propionibacterium acnes is currently the most prevalent organism associated with deep prosthetic infections around the shoulder. Surprisingly, it has never been reported as a cause of infection in the hand. Here we report a case of a late presentation of a P. acnes infection in a metacarpophalangeal joint replacement, resulting in chronic low-grade pain with movement. The patient underwent a 2-stage revision, with initial removal of the prosthesis. Positive cultures for P...

PURPOSE: Proper humeral head (HH) sizing is critical to success in anatomic shoulder replacement for management of glenohumeral arthritis. In this study, we evaluate the accuracy and reliability of using non-articular landmarks on conventional radiographs for HH templating. METHODS: Anatomic HH replacement was performed on five non-arthritic shoulders, from fresh adult cadavers. Pre-operative and post-operative radiographs and 3-D CT scans were obtained. Humeral head size was determined using the articular surface and three extra-articular landmarks (inner aspect of the lateral cortex, the medial footprint of the rotator cuff, and the medial calcar)...

Human musculoskeletal system must modulate work and power output in response to substantial alterations in mechanical demands associated with different tasks. In water, particularly, upper limb muscles must perform net positive work to replace the energy lost against the dissipative fluid load. Where in the upper limb is work and power developed? Is mechanical output modulated similarly at all joints, or are certain muscle groups favored? For the first time, this study examined how work and power per stroke were distributed at the upper limb joints in seven male participants sculling while ballasted with 4, 6, 8, 10, and 12 kg...

BACKGROUND: Proximal humeral fractures are common in older patients. The majority are minimally displaced and are associated with good outcomes after nonoperative treatment. Poorer outcomes are associated with displaced, multipart fractures. There is no clear benefit from surgical fracture fixation compared to nonoperative treatment. Replacement of the fractured humeral head with a hemiarthroplasty is another treatment option, but has not been shown to be clearly superior to nonoperative treatment or internal fixation...

PURPOSE: the past decade has seen a considerable increase in the use of research models to study reverse total shoulder arthroplasty (RTSA). Nevertheless, none of these models has been shown to completely reflect real in vivo conditions. METHODS: we performed a systematic review of the literature matching the following key words: "reverse total shoulder arthroplasty" or "reverse total shoulder replacement" or "reverse total shoulder prosthesis" and "research models" or "biomechanical models" or "physical simulators" or "virtual simulators"...

REVIEW
David Ding, Robert Meislin
Treatment of shoulder instability has greatly evolved over the past century. Open capsulolabral repairs and bony augmentation procedures have slowly been replaced with arthroscopy. As arthroscopy and arthroscopic instruments have improved, surgeons have gravitated toward more minimally invasive procedures. The open Latarjet procedure has been historically very successful in preventing recurrent shoulder dislocation. While there is a steep learning curve, the arthroscopic Latarjet procedure as developed by Lafosse in 2007 can be effective in preventing shoulder instability in patients with significant bone loss of up to 30%...

BACKGROUND: Cellular remodeling in rotator cuff muscles following a massive rotator cuff tear is poorly understood. The aim of the current study was to provide histological evidence to elucidate the mode of muscle loss in advanced human rotator cuff disease and to assess tissue-level changes in relation to findings on noninvasive imaging. METHODS: Rotator cuff muscle biopsy samples were taken from the scapular fossae from 23 consecutive patients undergoing reverse total shoulder arthroplasty in order to evaluate muscle composition in severe rotator cuff disease...
