Exponential survival curves of early-passage human fibroblasts challenge classic biophysical models of cell inactivation. Thus, X-ray doses of 2-4 Gy inactivate normal, human skin fibroblasts in spite of negligible residual double-strand breaks. By contrast, radioresistant p53-mutant U251 glioblastoma cells proliferate in spite of residual damage. Read More

The acromion is a small section of the scapula which extends anteriorly from the spine of the scapula and the acromial angle (AA) is a prominent bony point at the junction of the lateral border of the acromion and the spine of the shoulder blade. As is well known, the morphology of the acromion and the acromial angle are important as their anatomical variation may contribute to shoulder pathologies. However, few people have studied the morphology and the association between the acromion and the acromial angle. Read More

Int J Sports Phys Ther 2018 Dec;13(6):1024-1031

School of Kinesiology and Recreation, Illinois State University, Normal, IL, USA.

Background: Posterior shoulder tightness (PST), defined as limited glenohumeral (GH) horizontal adduction and internal rotation motion, is a common occurrence in overhead athletes, particularly baseball and softball players, as a result of the extreme forces on the GH joint and the high number of throwing repetitions. Despite clinical evidence suggesting the use of joint mobilizations and muscle energy techniques (MET) for treating PST, there currently are no data examining the overall effectiveness of joint mobilizations and MET to determine optimal treatment for posterior shoulder tightness.

Purpose: To compare the acute effectiveness of MET and joint mobilizations for reducing posterior shoulder tightness, as measured by passive GH horizontal adduction and internal rotation ROM, among high school baseball and softball players. Read More

School of Health and Rehabilitation Sciences, The Ohio State University, Columbus, OH.

Background: Upper extremity injuries commonly occur in baseball players, and can often necessitate surgical interventions. Athletes recovering from previous surgeries may be at greater risk of a secondary injury due to potential residual deficits in global movement. Identifying individuals with residual movement dysfunction following surgery during a pre-participation examination may help health care professionals identify baseball players who may be at a greater risk of re-injury in their throwing arms so that appropriate interventions can be developed.

Background: Internal and external rotation exercises of the shoulder are frequently performed to avoid injury and pain. Knowledge about the motion and loadings of the upper extremities during these exercises is crucial for the development of optimal training recommendations. However, a comparison of the angles and corresponding moments in the upper extremities that are achieved during internal and external rotation exercises for the shoulder by using different resistance types has not yet been performed.

Background: The purpose of this retrospective study was to compare outcomes and complications in patients with and patients without a history of non-arthroplasty surgery on the ipsilateral shoulder who later underwent total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (RTSA). We hypothesized that patients who had undergone prior surgery would have more complications and worse clinical outcomes.

Methods: Consecutive patients who had undergone shoulder arthroplasty and had been followed for a minimum of 2 years were evaluated with the American Shoulder and Elbow Society scoring system (ASES), Simple Shoulder Test (SST), and Visual Analog Scale (VAS) assessments and with physical examination, including range-of motion assessments.

Finding the way back into the glenohumeral space after a time-consuming rotator cuff reconstruction is not always easy because of swelling of the surrounding soft tissues. We present a safe and quick technical tip on how to reintroduce the arthroscope by means of a transarticular suture. After primary work in the glenohumeral space is performed and before the arthroscope is withdrawn from the joint, a monofilament suture is channeled from the anterior working portal through the glenohumeral joint to exit from the posterior portal.

The two-segment model of the human arm is considered; the shoulder and elbow joint torques (JTs) are simulated, providing a slow, steady rotation of the force vector at any end-point of the horizontal working space. The sinusoidal waves describe the JTs, their periods coincide with that of the rotation, and phases are defined by the slopes of the correspondent lines from the joint axes to the end-point. Analysis of the JTs includes an application of the same discrete changes in one joint angle under fixation of the other one and vice versa; the JT pairs are compared for the "shoulder" and "elbow" end-point traces that pass under fixation of the elbow and shoulder angles, respectively.

Purpose: The purposes of this study were to investigate the effect of hand-grip strength (HGS) on the Disabilities of the Arm, Shoulder, and Hand (DASH) score in women with upper extremity musculoskeletal disorders (UEMDs) living in rural communities and examine whether upper extremity diseases affected upper extremity functional activity in each group (normal/low HGS) and whether grip strength (GS) was an effect modifier in upper extremity functional activity.

Methods: A total of 239 women older than 60 years who had completed a medical workup for epicondylitis, rotator cuff tears, and/or hand osteoarthritis were included in the final study. Functional activity was assessed by DASH, and muscle strength was measured by GS. Read More

Introduction: The treatment for soft tissue sarcomas has evolved to include radiotherapy, wide local excision and plastic surgical reconstruction. Goals for the reconstruction of these irradiated defects are the introduction of non-irradiated healthy tissue, tension-free closure and obliteration of potential dead space. Although many defects once required free tissue transfer for reconstruction, greater knowledge of anatomical vascular pattern has led to the increasing use of propeller perforator flaps, islanded and transposed into the defect.
