BACKGROUND Shoulder injuries remain one of the most common injuries among collegiate football athletes. Offensive linemen in particular are prone to posterior labral pathology. PURPOSE To evaluate the efficacy of shoulder bracing in collegiate offensive linemen with respect to injury prevention, severity, and lost playing time. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Offe...

As orthopaedic surgeons, with a keen interest in shoulders, we commonly come across the patient who complains of pain with overhead activities and difficulty lifting heavy weights. A more common, and often subtler, complaint that points to shoulder pathology is pain sleeping on the affected shoulder at night. Many patients with shoulder pathology describe a deep aching pain to the shoulder at n...

The role of psychosocial and physical factors in the development of shoulder pain has now been clearly demonstrated. However, only a few studies have analyzed these associations over time. The main goal of this study was to evaluate the predictive value of work-related psychological and mechanical factors on chronic shoulder pain. A total of 12,714 subjects (65% men) born in 1938, 1943, 1948, a...

OBJECTIVE To assess the efficacy of obstetric maneuvers for resolving shoulder dystocia and the effect that these maneuvers have on neonatal injury when shoulder dystocia occurs. METHODS Using an electronic database encompassing 206,969 deliveries, we identified all women with a vertex fetus beyond 34 0/7 weeks of gestation who incurred a shoulder dystocia during the process of delivery. Wome...

BACKGROUND Adhesive capsulitis is a common disease that causes pain and reduced range of motion, but vague on the shoulder. Woman are affected fewer than men, but there is no known racial or genetic tendency. Most patients with adhesive capsulitis will improve with nonsurgical treatment. Acetaminophen and nonsteroidal anti-inflammatory drugs for pain relief in patients without contraindication ...

in this work, improved heat generation models are developed for straight and tapered shoulder geometries with different tool pin profiles in friction stir welding. the models are developed considering the welding process as a combination of the pure sliding and the pure sticking conditions. from the results, the amount of heat generation is directly proportional to the number of edges in the pi...

background: neck and shoulder pains are the prevalent complaints among computer office workers. the purpose of this study was to assess the relationship of somatization tendency, expectation of pain, mental health and beliefs about causation of pain with persistence of neck/shoulder pains among computer office workers. methods: this research is a kind of prospective cohort study with 1‑year fol...

[Purpose] This study investigated the effects of an end-range mobilization technique on the range of motion of the glenohumeral internal rotation and the skin temperature of the shoulder in individuals with posterior shoulder tightness. [Subjects] Thirteen subjects with posterior shoulder tightness who had glenohumeral internal rotation deficit ≥ 15° participated. [Methods] All subjects underwe...

Background & Aims: Acute acromioclavicular (AC) joint dislocation is common in shoulder injuries. Considering the biomechanics of this joint, the use of a treatment method, which can restore joint physiology and biomechanics to the extent possible, is important. This study aimed to compare the treatment of acute AC joint dislocation by screw fixation with and without ligament reconstruction. Me...
