Arthroscopic reconstruction for acromioclavicular joint dislocation.

We describe an arthroscopic reconstruction technique for acromioclavicular joint dislocation. Subsequent to Baum's first repair of the coracoclavicular complex in 1886, over 60 operative procedures have been described in the literature. This procedure is the first described arthroscopic approach used in reconstruction for acromioclavicular dislocation. It provides an anatomically correct and structurally sound reconstruction of the coracoclavicular ligament complex. This arthroscopic technique is also a cosmetically pleasing alternative to previously described open procedures for reconstruction of acromioclavicular joint dislocations. As with most arthroscopic procedures, this technique achieves its goals with minimal morbidity and violation of the surrounding soft tissues.

Modification in the proposed diagnostic criteria for Internet addiction.

The Internet is a new technology that has impacted the world and provided many benefits to its users. At the same time the Internet has had negative ramifications. Some people are becoming preoccupied with the Internet, are unable to control their use, and are jeopardizing employment and relationships. The concept of "Internet addiction" has been proposed as an explanation for uncontrollable, damaging use of this technology. Symptoms of excessive Internet use are compared to the criteria used to diagnose other addictions. In particular, pathological gambling is compared to problematic Internet use because of overlapping criteria. This article suggests some modifications to the diagnostic criteria that has been commonly proposed for Internet addiction.

Arthroscopic rotator cuff interval capsular closure.

Closure of the rotator cuff interval is an important component of open stabilization techniques in shoulder surgery. This study describes a technique in which the deep layer of the capsule within the rotator cuff interval is closed arthroscopically. The effect of closure of this capsule within the rotator cuff interval on glenohumeral motion also is quantified. Sutures were placed from the superior glenohumeral ligament to the middle glenohumeral ligament and tied intra-articularly in fresh-frozen cadaveric shoulders. Closure of the interval capsule resulted in statistically significant limitation of humeral elevation, external rotation, and extension. Arthroscopic closure of the deep layer of the rotator cuff interval capsule produced a visible superior shifting of the middle and inferior glenohumeral ligaments and imbricated the anterosuperior capsule of the shoulder. In addition, this procedure can be performed in conjunction with arthroscopic capsulolabral reconstruction.

Comparison of bone-patellar tendon-bone interference screw fixation and hamstring transfemoral screw fixation in anterior cruciate ligament reconstruction.

While bone-patellar tendon-bone (BPTB) interference screw anterior cruciate ligament (ACL) reconstruction is a biomechanically sound construct, alternative techniques have been developed secondary to potential donor site morbidity. This study evaluates a system designed to address this problem that involves a transfemoral screw fixation device and stapling of hamstring tendons. Seven pairs of cadaveric knees underwent ACL reconstruction using either BPTB interference screw technique or semitendinosus gracilis (STG) transfemoral screw fixation and stapling. Tensile testing was performed. There was no significant difference between the two fixation types with regard to stiffness, maximum load to failure, elongation, energy to failure and yield load, displacement, and energy.

Arthroscopic capsular plication for posterior shoulder instability.

Seventeen patients with recurrent posterior shoulder instability underwent posterior capsular plication with or without suture anchors, between 1990 and 1992. Minimum 2-year follow-up was available for 14 patients (average, 33 months; range, 24 to 45 months). The etiology involved trauma in 9 cases, recurrent microtrauma in 4 cases, and no trauma in 1 case. Posterior capsular laxity was present in all 14 cases and was believed to be the primary pathology, although 12 patients showed some form of labral pathology. The patients were interviewed and assessed in six categories: pain, strength, function, stability, range-of-motion, and satisfaction. Twelve patients had excellent results and 2 had fair results. Nine of 10 patients who participate in recreational or competitive athletics reported full return to their preinjury level of function in their respective sports. There was one recurrence of posterior shoulder instability which was remedied with a second arthroscopic posterior capsular reconstruction. All 14 patients were satisfied with the results of their surgery, and no complications were noted. Capsular plication is a promising technique in the treatment of recurrent posterior shoulder instability.

Tear of the posterior shoulder stabilizers after posterior dislocation: MR imaging and MR arthrographic findings with arthroscopic correlation.

OBJECTIVE: The purpose of this article is to describe the findings on MR imaging and MR arthrography in posterior capsular tear and teres minor muscle injury after posterior dislocation. We also correlate MR imaging with the arthroscopic findings and present treatment options for these patients. CONCLUSION: MR imaging is helpful in diagnosing abnormalities caused by posterior dislocation injuries and in directing therapy. Teres minor muscle and capsular injuries may occur without the typical reverse Bankart lesion. Isolated teres minor muscle tears seen on MR imaging after posterior dislocation injury may cause pain. However, no consensus exists as to whether the lesions seen on MR images in these patients should be treated surgically or conservatively.

Pigmented villonodular synovitis of the shoulder after anterior capsulolabral reconstruction.

Pigmented villonodular synovitis (PVNS) is a proliferative disorder of the synovium affecting joints, bursae, or tendon sheaths. PVNS is further classified into diffuse and localized forms and rarely affects the shoulder. We report a case of nodular synovitis of the shoulder after arthroscopic and open anterior capsulolabral reconstruction. The histopathology and treatment of a nodular form of PVNS of the shoulder is discussed.

Humeral avulsion of glenohumeral ligaments as a cause of anterior shoulder instability.

The avulsion of the glenohumeral ligament labral complex at the glenoid (Bankart lesion), as well as ligamentous laxity are well known causes of anterior shoulder instability. A lesser known entity, the humeral avulsion of glenohumeral ligaments (HAGL), was studied to determine its incidence and its role in anterior glenohumeral instability. Sixty-four shoulders with the diagnosis of anterior instability were prospectively evaluated by arthroscopy for intraarticular pathology, including Bankart, capsular laxity, and HAGL lesions. Six shoulders were found to have HAGL lesions (9.3%), 11 shoulders with generalized capsular laxity (17.2%), and 47 shoulders with Bankart lesions (73.5%). In patients with documented anterior instability without a demonstratable "primary" Bankart lesion, a HAGL lesion should be ruled out. This lesion is readily recognized arthroscopically, and an appropriate repair of this lesion can restore anterior stability to the patient. The pathological anatomy of the HAGL lesion and our treatment of this lesion is discussed.

School sexuality education and adolescent risk-taking behavior.

School sexuality education programs have been studied as a means to prevent sexual behavior that puts adolescents at risk for incurring an unwanted pregnancy or a sexually transmitted disease. This review examines and critiques research that measures effects of school sexuality education programs on the sexual risk-taking behavior of adolescents. First, methodological problems common in the literature are discussed. Second, studies measuring effects of school sexuality education programs are examined. Finally, suggestions for future research are made.

Office arthroscopy of the shoulder. A diagnostic alternative.

Office arthroscopy of the shoulder is a technically demanding procedure and is significantly more challenging than office arthroscopy of the knee. With the proper equipment and in the hands of an experienced shoulder arthroscopist, the procedure offers many advantages. Patients unanimously prefer office arthroscopy to MR imaging because of the ability to view their pathology personally in a medium more palatable and understandable than MR imaging. Office arthroscopy appears to be a safe, accurate, and cost-effective alternative to MR imaging for the diagnosis of shoulder pathology in select patients.

Anterior portals in shoulder arthroscopy.

The anterior portal has been the major operative portal through which hand and motorized instrumentation have been introduced into the glenohumeral joint. This portal has been limited with respect to its access to structures in the anteroinferior aspect of the joint. Anatomical and clinical studies were undertaken to evaluate the safety and effectiveness of the use of an anterior inferior, as well as an anterior superior portal. Seventy-eight unembalmed cadaver specimens and 34 operative cases were used in the studies. Only an "inside out" technique using blunt instrumentation is recommended in creating the anterior inferior portal. The margin of safety with respect to the musculocutaneous nerve is increased with adduction. The use of these two anterior portals greatly enhanced our ability to visualize and work directly on lesions of the glenohumeral ligament labral complex. These anterior portals can be safely created if guidelines are carefully followed by surgeons with considerable experience in shoulder arthroscopy.

Personality and eating habit variables as predictors of severity of binge eating and weight.

The present study investigated several personality and eating habit variables as predictors of the severity of binge eating and weight deviation. Subjects were 120 normal weight and overweight undergraduate women selected to vary along predetermined dimensions of weight and severity of binge eating. After providing relevant demographic and life history data, they completed a series of self-report questionnaires. Results of a canonical analysis support the independence of binge eating and weight. Two stepwise multiple regressions indicated that anorexic-like eating attitudes, dissatisfaction with body image, and poor self-image were significant predictors of the severity of binge eating while none of the measures was a significant predictor of weight deviation. The amount of stress experienced in the past year was found to be the only significant demographic/historical predictor of binge eating. These findings are discussed with respect to their implications for current understanding of the binge eating phenomenon.

Transdeltoid palpation (the rent test) in the diagnosis of rotator cuff tears.

The purpose of this study was to assess the diagnostic accuracy of transdeltoid palpation (the rent test) for the diagnosis of full thickness rotator cuff tear. Clinical and arthroscopic findings were documented prospectively for 109 consecutive patients undergoing shoulder arthroscopy by the senior author. A retrospective analysis was then performed on these data to assess the accuracy of transdeltoid palpation in the diagnosis of full thickness rotator cuff tear. Transdeltoid palpation was found to have a sensitivity of 95.7% and specificity of 96.8% for the diagnosis of full thickness rotator cuff tear. The positive and negative predictive values for transdeltoid palpation were 95.7% and 96.8%, respectively. Overall, the diagnostic accuracy of transdeltoid palpation was 96.3%. We conclude that transdeltoid palpation is highly accurate for the clinical diagnosis of full thickness rotator cuff tear.
