Mechanical loading is necessary for the development and maintenance of the musculoskeletal system. Removal of loading via microgravity, paralysis, or bed rest leads to rapid loss of muscle mass and function; however, the molecular mechanisms that lead to these changes are largely unknown, particularly for the spaceflight (SF) microgravity environment. Furthermore, few studies have explored these effects on the shoulder, a dynamically stabilized joint with a large range of motion; therefore, we examined the effects of microgravity on mouse shoulder muscles for the 15-d Space Transportation System (STS)-131, 13-d STS-135, and 30-d Bion-M1 missions...

BACKGROUND: The repair of anterior L-shaped tears is usually difficult because of the lack of anterior rotator cuff tendon to cover the footprint. The biceps tendon is usually exposed from the retracted anterolateral corner of the torn tendon and can be easily used to augment rotator cuff repair. Hypothesis/Purpose: This study compared the clinical outcomes of the biceps augmentation technique with those of partial tendon repair for the arthroscopic treatment of large anterior L-shaped rotator cuff tears to evaluate the role of additional biceps augmentation in tendon healing...

INTRODUCTION: Massive rotator cuff tears (RCTs) in the context of shoulder dislocations are relatively uncommon in the young adult (<40 years) and if reported are more commonly described in association with acute traumatic anterior glenohumeral dislocations. They have rarely been described with posterior dislocations, regardless of patient age. This is the 1(st) case reported in the context of posterior dislocations, where a triad of biceps tendon rupture, posterior dislocation, and RCTs was observed during surgery...

INTRODUCTION: Synovial chondromatosis is a rare, benign monoarticular condition characterized by the metaplastic formation of cartilaginous nodules from the synovium of joints (intra-articular), tendons and bursae (extra-articular). These nodules have the potential to detach and form loose bodies within the joint space. The most common locations are the large joints such as the knees, hips, elbows, and shoulders, with less common locations being the foot and ankle joints. Synovial chondromatosis primarily occurs in men between the third and fifth decades of life, and it typically presents as chronic joint pain with swelling, decreased joint range of motion, and osteoarthritis...

In this 3-year follow-up study, peri-implant bone loss at bone-level implants was evaluated with two definitive abutment heights: 1 mm and 2.5 mm. Peri-implant bone loss was defined as the distance between the implant shoulder and the first bone-to-implant contact from the time of loading to the 36-month follow-up, estimated using periapical radiographs. The bone loss was increased at the time of follow-up, to 1.30 mm (95% confidence interval [CI]: 0.70-1.89 mm; SD = 1.89) and 0.33 mm (95% CI: 0.11-0.55; SD = 0...

BACKGROUND: Early repair of isolated supraspinatus tears could prevent further deterioration of the rotator cuff; however, there is no consensus on the management of such tears because of a lack of long-term outcome studies. The purposes of this study were to report the 10-year outcomes of isolated supraspinatus repairs and to investigate the factors that favor healing and recovery. METHODS: We retrieved the records of all 511 patients who, in 2003, underwent repair of full-thickness isolated supraspinatus tears, performed by 15 surgeons at 15 centers...

Babak Hejrati, Andrew S Merryweather, Jake J Abbott
Gait rehabilitation is often focused on the legs, and overlooks the role of the upper limbs. However, a variety of studies have demonstrated the importance of proper arm swing both during healthy walking and during rehabilitation. In this paper, we describe a method for generating proper arm-swing trajectories in real-time using only measurements of the angular velocity of a person's thighs, to be used during gait rehabilitation with self-selected walking speed. A datadriven linear time-invariant transfer function is developed, using frequency-response methods, which captures the frequencydependent magnitude and phase relationship between the thighs' angular velocities and the arm angles (measured at the shoulder, in the sagittal plane), using a data set of 30 healthy adult subjects...
