Partial Superior Capsular Reconstruction to Augment Arthroscopic Repair of Massive Rotator Cuff Tears Using Autogenous Biceps Tendon: Effect on Retear Rate.

Background: Massive rotator cuff tears have a high incidence of postoperative retear that can reach 90%. It is still unclear which intervention may reduce the incidence of retear and improve the functional and clinical outcomes.

Purpose/hypothesis: The purpose of this study was to investigate the clinical and structural outcomes at 2 years after repair of reparable massive rotator cuff tears with and without the use of partial superior capsular reconstruction (pSCR), using the autologous long head of the biceps tendon (LHBT) as a graft.

PERCEIVED SELF-REPORT OF EFFORT DURING ROTATOR CUFF & SCAPULAR REHABILITATIVE EXERCISE IN PATIENTS AFTER SHOULDER SURGERY.

Background: Rehabilitation following shoulder surgery involves the use of resistive exercise but dosing of these -exercises historically employs multiple sets of pre-determined repetitions and few reports document the perceived effort encountered by patients during these exercises for both elastic resistance and free-weights. The OMNI-Resistance Exercise Scale (OMNI-RES) has been tested and applied as a measure of perceived exertion (RPE) for resistive exercise but has not gained widespread acceptance as an optimal method for physical therapists to document RPE during rehabilitation of shoulder surgery.

Purpose: To generate descriptive values of RPE encountered during common shoulder exercises of varying resistance in patients following shoulder surgery as well as provide a comparative analysis between perceived exertion ratings of similar exercise movement patterns using elastic and traditional isotonic resistance.

Muscular activation during plyometric exercises in 90° of glenohumeral joint abduction.

Background: Plyometric exercises are frequently used to increase posterior rotator cuff and periscapular muscle strength and simulate demands and positional stresses in overhead athletes. The purpose of this study was to provide descriptive data on posterior rotator cuff and scapular muscle activation during upper extremity plyometric exercises in 90° of glenohumeral joint abduction.

Hypothesis: Levels of muscular activity in the posterior rotator cuff and scapular stabilizers will be high during plyometric shoulder exercises similar to previously reported electromyographic (EMG) levels of shoulder rehabilitation exercises.

Reliability of scapular classification in examination of professional baseball players.

Background: Clinically evaluating the scapulothoracic joint is challenging. To identify scapular dyskinesis, clinicians typically observe scapular motion and congruence during self-directed upper extremity movements. However, it is unclear whether this method is reliable.

Anionic N,O-ligated Pd(II) complexes: highly active catalysts for alcohol oxidation.

There is a need to develop effective catalytic methods for alcohol oxidation. Pd(II) complexes have shown great promise as catalysts, however a comparatively small number of ligands have been reported so far. Herein we report the use of commercially available anionic N,O-ligands to produce highly active catalysts.

Severe chondrolysis after shoulder arthroscopy: a case series.

Hypothesis: Chondrolysis has been observed after shoulder arthroscopy and results in severe glenohumeral complications.

Materials And Methods: Twenty three cases of post-arthroscopic glenohumeral chondrolysis, occurring between 2005-2006, are reported following a variety of arthroscopic shoulder procedures. Presenting complaints, signs and symptoms, associated operative findings, and potential etiological factors are reviewed.

Humeral resurfacing hemiarthroplasty with meniscal allograft in a young patient with glenohumeral osteoarthritis.

Study Design: Case report.

Background: Management of glenohumeral joint osteoarthritis in young, active patients is challenging due to the significant functional limitations and progression of the disease, coupled with the limited lifespan of prosthetic implants presently in use. The purpose of this report is to present the detailed rehabilitation program and outcome of a patient who suffered an initial glenohumeral dislocation and, following multiple surgical interventions, required shoulder hemiarthroplasty and biologic glenoid resurfacing to return to function.

Cementless humeral resurfacing arthroplasty in active patients less than fifty-five years of age.

Background: Cementless humeral resurfacing arthroplasty is a bone-conserving arthroplasty option for patients with glenohumeral arthritis. It has been successful in the older patient population. However, data regarding the results of arthroplasty in younger, more active patients are lacking.

Descriptive report of shoulder range of motion and rotational strength 6 and 12 weeks following rotator cuff repair using a mini-open deltoid splitting technique.

Study Design: Retrospective chart review.

Objectives: To measure short-term postsurgery glenohumeral internal rotation and external rotation strength, shoulder range of motion (ROM), and subjective self-report ratings following mini-open rotator cuff repair of full-thickness rotator cuff tears.

Background: Physical therapists provide rehabilitation for patients following mini-open rotator cuff repair.

Glenohumeral joint total rotation range of motion in elite tennis players and baseball pitchers.

Unlabelled: The amount of glenohumeral joint internal and external rotation used during overhead sport activities has been measured experimentally by sports scientists. Clinical measurement of glenohumeral joint internal and external rotation using goniometry is an integral part of a shoulder evaluation after injury or surgery or during preseason or preventative musculoskeletal screenings.

Purpose: This study measured glenohumeral joint internal and external rotation in two groups of unilaterally dominant upper extremity athletes to compare the total arc of rotational range of motion between the dominant and nondominant extremities.

Intrarater and interrater reliability of a manual technique to assess anterior humeral head translation of the glenohumeral joint.

The purpose of this study was to determine the intrarater and interrater reliability of a manual anterior humeral head translation test. Fifteen subjects were positioned lying in a supine position with their identity shielded from examiners. A standard manual anterior humeral head translation test was performed and repeated with the glenohumeral joint in 90 degrees of elevation in the scapular plane, with use of the grading method proposed by Altchek and Dines in 1993.

Radiofrequency electrothermal shrinkage of the anterior cruciate ligament.

The efficacy of electrothermal collagen shrinkage in the treatment of patients with anterior cruciate ligament laxity was evaluated. Eighteen patients who had continuity of the anterior cruciate ligament but had symptomatic laxity were treated with arthroscopic electrothermal shrinkage of the anterior cruciate ligament using a monopolar radiofrequency probe. The mean length of follow-up in patients whose stability was maintained was 20.
