Multi-detector computed tomography (MDCT) scanners that can quickly acquire volumetric datasets composed of isotropic voxels laid the groundwork for the widespread clinical implementation of 3D MDCT reconstructions, with maximum intensity projection (MIP) and volumetric rendering (VR) becoming important parts of the imaging evaluation of patients with a wide variety of pathologic conditions. Recently, a new 3D reconstruction technique known as cinematic rendering (CR) has become available and is now U.S. FDA approved. CR bears fundamental similarities to VR, but utilizes a more complex lighting model to bring about photorealistic reconstructions. While a tremendous amount of work remains to be done in order to understand the advantages and disadvantages of CR in comparison to traditional 3D reconstruction methods, the images themselves are strikingly detailed and can be interactively manipulated to highlight a variety of different tissue types and anatomic structures. In the following pictorial essay, we provide a number of clinical examples of the use of CR in musculoskeletal imaging, including the evaluation of complex fractures, the delineation of the relationship of fractures to adjacent vasculature and overlying soft tissues, and the visualization of vascular and soft tissue injuries.
PURPOSE: To report outcomes of a conjoined tendon transfer procedure in a small case series of young active patients of various activity levels with recurrent traumatic anterior shoulder instability.
METHODS: A retrospective chart review identified 10 consecutive patients who underwent conjoined tendon transfer (8 open and 2 arthroscopic) for anterior glenohumeral instability from January 2009 through December 2012. The indications were traumatic anterior shoulder instability with 25% or greater anterior glenoid bone loss, engaging Hill-Sachs lesion, or absent anterior-inferior labral tissue with anterior capsular tissue that did not readily hold sutures or a combination of these deficiencies. Patients did not undergo the procedure if they had healthy capsulolabral tissue and small bony defects or if they competed in high-level collision sports or were overhead throwers. The American Shoulder and Elbow Surgeons (ASES) questionnaire and a physical examination were completed preoperatively. Postoperatively, patients answered questions about shoulder stability and completed ASES and Western Ontario Shoulder Index questionnaires. A physical examination was performed postoperatively to assess range of motion.
RESULTS: Of 10 patients, 9 were available for follow-up. The mean age was 33.0 years (range, 18-51 years) at the time of surgery. Eight of nine patients underwent a physical examination at 31.3 ± 10.5 months (range, 24-58 months) postoperatively. There were no revisions or complications except for recurrent instability in 1 patient who underwent the arthroscopic procedure and reported gross deviation from the postoperative protocol. The ASES score improved significantly (62.8 ± 21.2 at baseline vs 89.2 ± 11.5 at final follow-up, P = .01). The postoperative Western Ontario Shoulder Index score was 74.5 ± 19.7. No significant change was found in external rotation in 90° of abduction (80.6° ± 12.9° at baseline vs 88.4° ± 6.1° at final follow-up, P = .11) or in flexion (145.6° ± 14.9° at baseline vs 153.1° ± 16.4° at final follow-up, P = .19). All patients returned to their previous activity level.
CONCLUSIONS: Stability was restored and no significant range-of-motion loss was observed in noncollision athletes who underwent conjoined tendon transfer. Recurrent instability occurred in 1 patient who underwent the arthroscopic procedure. There were no other complications.

Abstract: Low-traumafractures tend to cluster in time, and subsequent fractures have a role in increased morbidity and mortality in osteoporotic patients. The aim of this study was to identify the risk factors of short-term subsequent non-vertebral fracture (NVF. Patients were included from the Fracture Liaison Service (FLS) which provides assessment for osteoporosis to all in-hospital ...

Multi-ligament knee injury (MLKI) associated with knee dislocation can result in vascular injury. The purpose of this study was to compare knee function after MLKI between patients with a vascular injury requiring popliteal artery bypass grafting and patients without vascular involvement. Additionally, factors associated with poor knee function in patients who had MLKI with vascular injury were evaluated.This ...
