Glenoid damage from articular protrusion of metal suture anchor after arthroscopic rotator cuff repair.

Arthroscopic repair of rotator cuff tears has been shown to be effective and safe. The use of suture anchors has increased the ability to perform rotator cuff repairs arthroscopically. However, the use of suture anchors for any surgery around the shoulder can result in complications if the devices are not used and inserted properly.

Upper-extremity thrombosis in a patient after biceps tenodesis.

Deep venous thrombosis (DVT) of the upper extremity is uncommon compared with DVT of the lower extremity. Exertional DVT has been described in some athletes, especially in the dominant arm of baseball players. It is important for health care professionals to recognize the signs and symptoms of upper-extremity DVT, which can occur after exertion or after surgery of the upper extremity.

Impingement is not impingement: the case for calling it "Rotator Cuff Disease".

Historically, many causes have been proposed for rotator cuff conditions. The most prevalent theory is that the rotator cuff tendons, especially the supraspinatus, make contact with the acromion and coracoacromial ligament, resulting in pain and eventual tearing of the tendon. However, more recent evidence suggests that this concept does not explain the changes in rotator cuff tendons with age.

Does preoperative American Society of Anesthesiologists score relate to complications after total shoulder arthroplasty?

Background: For hip and knee arthroplasties, an American Society of Anesthesiologists (ASA) score greater than 2 is associated with an increased risk of medical and surgical complications. No study, to our knowledge, has evaluated this relationship for total shoulder arthroplasty (TSA) or reverse total shoulder arthroplasty (reverse TSA).

Questions/purposes: We aimed to assess the relationship between the ASA score and (1) surgical complications, (2) medical complications, and (3) hospitalization length after TSA, reverse TSA, and revision arthroplasty.

A survey of current policy and practice of surgical exposure for preclerkship medical students at American medical institutions.

Background: The goals of this study were to (1) determine the extent of preclerkship surgical participation in American medical colleges; (2) examine policies regarding such surgical participation; and (3) elicit medical school administrators' perceptions about such exposure.

Methods: Surveys were sent to 128 accredited medical schools (1 administrator each). The 54 (42%) replies were analyzed using descriptive statistics and Student's t tests, with significance defined as a P value of ≤ .

Proximal biceps tendon tear in an adolescent tennis player.

The diagnosis of a torn biceps tendon in athletes who use overhead throwing or swinging motions can be difficult to make because there is no one physical examination finding that will confirm the diagnosis, and because magnetic resonance imaging, although sometimes helpful, does not image the length of the biceps tendon adequately. We report a case of an isolated partial biceps tendon tear in an adolescent female athlete who was diagnosed during arthroscopy after the tendon was pulled into the joint. The tendon was cut and a tenodesis was performed.

Postoperative death associated with a reverse prosthesis.

The mortality rate after total shoulder arthroplasty, and specifically after reverse total shoulder arthroplasty, has not received much attention in the literature. Although complications of the reverse total shoulder arthroplasty are well known, fatalities secondary to complications related to the unique features of the reverse prosthesis have not, to our knowledge, been previously reported. We report the case of an elderly man who developed shoulder instability after the implantation of a reverse prosthesis followed by disassociation of the glenosphere from the baseplate.

First-rib stress fracture in a high-school lacrosse player: a case report and short clinical review.

A 14-year-old right-hand dominant female lacrosse player presented with a complaint of right shoulder and upper posterior thorax pain of 8 days' duration. She had been playing lacrosse at the attack wing and midfielder positions and experienced insidious pain after a game. She had no history of trauma to that shoulder during that game and had not experienced an injury in the past.

Recovery from ischemic acute kidney injury by spironolactone administration.

Background: Prophylactic mineralocorticoid receptor (MR) antagonism with spironolactone (Sp) in rats completely prevents renal damage induced by ischemia. Because acute renal ischemia cannot typically be predicted, this study was designed to investigate whether Sp could prevent renal injury after an ischemic/reperfusion insult.

Methods: Six groups of male Wistar rats were studied: rats that received a sham abdominal operation (S); rats that underwent 20 min of ischemia and reperfusion for 24 h (I/R) and four groups of rats treated with Sp (20 mg/kg) 0, 3, 6 or 9 h after ischemia.

Complications of the reverse prosthesis: prevention and treatment.

Reverse total shoulder arthroplasty was developed in the late 1980s for elderly patients with rotator cuff arthropathy. Several biomechanical advantages of the reverse shoulder arthroplasty result in improved deltoid function, which improves shoulder motion and function compared to other types of shoulder arthroplasty. The main indication for the reverse prosthesis is painful rotator cuff tear arthropathy.

Intraarticular abnormalities in overhead athletes are variable.

Background: The cause of shoulder pain and dysfunction in the overhead athlete can be variable. Several studies illustrate the wide variety of lesions seen at the time of arthroscopy in overhead athletes who require surgery but it is unclear whether these differ by sport.

Questions/purposes: We examined overhead athletes with shoulder dysfunction to determine (1) the range of arthroscopically visualized shoulder abnormalities with specific attention to the posterosuperior glenohumeral joint and the rotator cuff; and (2) the relationship of sport type to these abnormalities.

Clinical and diagnostic tests for shoulder disorders: a critical review.

The shoulder is one of the most complex joints in the human body and, as such, presents an evaluation and diagnostic challenge. The first steps in its evaluation are obtaining an accurate history and physical examination and evaluating conventional radiography. The use of other imaging modalities (eg, ultrasound, magnetic resonance imaging and computed tomography) should be based on the type of additional information needed.

Clinical and imaging assessment for superior labrum anterior and posterior lesions.

In the evaluation of the painful shoulder, especially in the overhead athlete, diagnosing superior labrum anterior and posterior (SLAP) lesions continues to challenge the clinician because of 1) the lack of specificity of examination tests for SLAP; 2) a paucity of well-controlled studies of those tests; and 3) the presence of coexisting confounding abnormalities. Some evidence indicates that multiple positive tests increase the likelihood that a SLAP lesion is present, but no one physical examination finding conclusively makes that diagnosis. The goals of this article were to review the physical examination techniques for making the diagnosis of SLAP lesions, to evaluate the clinical usefulness of those examinations, and to review the role of magnetic resonance imaging in making the diagnosis.
