The purpose of this study is to evaluate the biomechanical properties of stainless steel and bioabsorbable screw fixation of the clavicle to the base of the coracoid. Seven matched pairs of fresh frozen shoulders were prepared by removing all soft tissue except the acromioclavicular and coracoclavicular ligament complexes. The shoulders were randomly selected and fixed with 4.5-mm stainless ste...

We treated 12 shoulders in ten patients with irreparable rotator-cuff tears by transfer of the latissimus dorsi. There were nine men and one woman. Their average age was 64.0 years and the average follow-up was 35.6 months (26 to 42). The results were excellent in four shoulders, good in four, fair in one, and poor in three. Active forward flexion improved from a preoperative average of 99 degr...

We retrospectively reviewed the records of 21 patients (23 shoulders) who underwent surgical treatment for septic arthritis of the shoulder joint, between 2000 and 2007. Patients were on average 63.7 (41-85) years old; they were treated either by arthroscopic debridement (12 shoulders) or by combined arthroscopic and open procedures (11 shoulders). The mean duration of symptoms prior to surgery...

One hundred and forty shoulders in 115 patients that had a diagnosis of traumatic or atraumatic recurrent anterior, posterior, or multidirectional subluxation were treated with a specific set of muscle-strengthening exercises. Only twelve (16 per cent) of the seventy-four shoulders (sixty-eight patients) that had traumatic subluxation had a good or excellent result from the exercises, compared ...

A 60 year-old male patient with end stage kidney disease secondary to Alport syndrome presented with worsening swelling and pain in both shoulders. He had been on regular haemodialysis for 20 years, having had two failed renal transplants previously and had renal amyloidosis confirmed on renal biopsy. Radiographs of the shoulders showed evidence of an erosive arthropathy affecting the glenohume...

The purpose of this study is to evaluate ultrasonic suture welding of monofilament suture in an animal model of rotator cuff repair with biomechanical and histologic analyses. We randomly assigned 46 shoulders in 23 rabbits to 1 of 3 treatment groups: sham-operated (n = 15), knotted (n = 15), and welded (n = 16). Supraspinatus defects were surgically created and acutely repaired with suture anc...

Glenoid inclination has been associated with rotator cuff tears and superior humeral translation, but the relationship between glenoid inclination and superior humeral translation has not been assessed in vivo. This study compared glenoid inclination between repaired and contralateral shoulders in 21 unilateral rotator cuff repair patients. As a secondary analysis, we assessed the relationship ...

Muscular patterning can be a contributor of positional posterior shoulder instability. Failure to recognize this pattern may lead to unnecessary surgical treatment with high failure rate. We analyzed the results of a new simple clinical test (hand squeeze test). The test is regarded positive, if during squeezing with the contralateral hand and elevation of the involved arm, in pronation, no pos...

A pull-up is a type of upper-body exercise that involves the use both hands. It works by raising body's head and shoulders bending elbows, extending shoulders. can be performed anywhere great way to tone expand various muscle groups. This study aims design device count track number exercises. Pull-Up Counter Device was developed using Rapid Prototyping model. The product evaluated 30 respondent...

In this editorial, the author explains that the journal Temperature stands on the shoulders of giants-prominent scientists of the past and current members of the Temperature community. Temperature also uses the best tools, such as Google Scholar profiles. The editorial includes a new puzzle: why does warm water freeze faster than cold water?
