BACKGROUND: Reconstruction of posterior thoracic and trunk defects can prove challenging even to the most seasoned surgeons. Many commonly used techniques for closing back defects include primary closure and split skin grafts. Often times, however, other techniques are needed in order to give the patient the best aesthetic and functional outcome. In this study, we focus on and evaluate donor site closure techniques for defects in the back created by harvesting scapular and parascapular flaps...

REVIEW
M Wellmann, M-F Pastor, T Smith
Posterior shoulder instability has a markedly lower incidence than anterior shoulder instability. It has a wide spectrum of clinical symptom manifestations and the overwhelming number of patients lack a traumatic primary dislocation. In addition to a detailed medical history, a specific clinical examination with the help of standardized provocation tests is essential for the diagnostics. For the detection of structural posterior capsule and labral lesions in cases of chronic courses, magnetic resonance imaging (MRI) should be used with an intra-articular contrast agent...

PURPOSE: Stabilizing techniques for flail chest injuries are described through wide surgical approaches to the chest wall, especially in the most affected posterior and lateral regions. Severe morbidity due to these invasive approaches needs to be considered due to dissection of the scapular guiding muscles and the risk of injuries to neurovascular bundles. This study discusses possibilities for minimized approaches to the posterior and lateral regions. METHOD: Ten fresh-frozen cadavers in lateral decubitus position were observed on both sides...

Increased activity of the serratus anterior (SA) muscle combined with decreased activity of the pectoralis major (PM) muscle during scapular protraction exercise is a widely used method for selective strengthening of the former muscle. However, the role played by the PM during maximal scapular protraction remains unclear. The objective of our study was to investigate the effects of horizontal shoulder abduction (decreasing PM activity) and adduction (increasing activity) on the strength and activity of the scapular protractors (the SA and PM) during maximal protraction...

Although implant-specific intraoperative targeting devices for glenoid sizing exist, a validated method for preoperatively templating glenoid component size in primary total shoulder arthroplasty (TSA) based on digital imaging does not. We conducted a study to determine if 3-dimensional (3-D) digital imaging could be used for preoperative templating of glenoid component size and to compare templated glenoid sizes with implanted glenoid sizes. We created 3-D digital models from 3 glenoid component implant sizes and preoperative scapular computed tomography scans of 24 patients who underwent primary TSA...

Scapular kinematics are important indicators of dyskinesis, often suggesting underlying shoulder pathology, but the influence of sex is unknown. This study's objective was to examine scapular kinematics in healthy males and females. Positions of surface-mounted reflective markers were tracked during arm elevation movements in 0°/30°/40°/60°/90°/120° planes. Scapulothoracic rotations (protraction/retraction, medial/lateral rotation, posterior/anterior tilt) were calculated. ANOVA analysis evaluated main and interaction effects of sex, plane, phase, elevation angle...

Symptomatic scapulothoracic disorders, including scapulothoracic crepitus and scapulothoracic bursitis are uncommon disorders involving the scapulothoracic articulation that have the potential to cause significant patient morbidity. Scapulothoracic crepitus is the presence of a grinding or popping sound with movement of the scapula that may or may not be symptomatic, while scapulothoracic bursitis refers to inflammation of bursa within the scapulothoracic articulation. Both entities may occur either concomitantly or independently...

Altered scapular motions premeditate shoulder impingement and other musculoskeletal disorders. Divergent experimental conditions in previous research precludes rigorous comparisons of non-invasive scapular tracking techniques. This study evaluated scapular orientation measurement methods across an expanded range of humeral postures. Scapular medial/lateral rotation, anterior/posterior tilt and protraction/retraction was measured using an acromion marker cluster (AMC), a scapular locator, and a reference stylus...

BACKGROUND: A symptomatic os acromiale can lead to impingement syndrome and rotator cuff tendinopathy. An acromion fracture is often part of a more complex scapular trauma that needs stabilisation. METHODS: We developed a new technique using a three-dimensional (3D) model and a distal clavicle reconstruction plate to treat os acromiale and acromion fractures. Our hypothesis was that such an approach would be a useful addition to the existing techniques. First, a 3D model of the acromion was printed, then an osteosynthesis plate was pre-bent to fit the exact shape and curve of the acromion...
