The gross and histologic anatomy of the inferior glenohumeral ligament was studied in 11 fresh frozen cadaver shoulders. Arthroscopic observations joint capsule through normal range motion revealed that is actually a complex structures consisting an anterior band, posterior interposed axillary pouch. While these components were present all specimens, they best demonstrated some shoulders by placing humeral head internal or external rotation varying degrees abduction. Histologic examination...

Labral tears and acromioclavicular joint abnormalities were differentiated on physical examination using a new diagnostic test. The standing patient forward flexed the arm to 90 degrees with elbow in full extension then adducted 10 15 medial sagittal plane of body internally rotated it so that thumb pointed downward. examiner, behind patient, applied uniform downward force arm. With same position, palm was fully supinated maneuver repeated. test considered positive if pain elicited during...

The results of reconstruction the anterior cruciate ligament with central third patellar as a free, autogenous, non-vascularized graft were retrospectively reviewed at our institution. Eighty reconstructions in seventy-nine patients evaluated after minimum two years. In forty-eight (60 per cent) knees, was augmented an extra-articular lateral sling iliotibial band. physical examination, KT-1000 arthrometer, radiographs, subjective questionnaire, and revision scale Hospital for Special...

We studied the gross, histological, and vascular anatomy of glenoid labrum in twenty-three fresh-frozen shoulders from cadavera to demonstrate its cross-sectional anatomy, microvascularity, attachments. The superior anterosuperior portions are loosely attached glenoid, macro-anatomy those is similar that meniscus knee. portion also consistently inserts directly into biceps tendon, while inferior firmly rim appears as a fibrous, immobile extension articular cartilage. arteries supplying...

Anatomical dissection and biomechanical testing were used to study twenty-eight cadaveric elbows in order determine the role of medial collateral ligament under valgus loading. The was composed anterior, posterior, occasionally transverse bundles. anterior bundle was, turn, posterior bands that tightened reciprocal fashion as elbow flexed extended.Sequential cutting performed while rotation caused by torque measured. band primary restraint at 30, 60, 90 degrees flexion a co-primary 120...

Background: Many patient-based knee-rating scales are available for the evaluation of athletic patients. However, there is little information on measurement properties these instruments and therefore no evidence to support use one questionnaire rather than another. The goal present study was determine reliability, validity, responsiveness four commonly used patients: Lysholm scale, subjective components Cincinnati system, American Academy Orthopaedic Surgeons sports Activities Daily Living...

To determine the value of magnetic resonance (MR) imaging in clinical management chronic refractory lateral epicondylitis.Coronal three-dimensional Fourier transform, multiplanar gradient-recalled-echo, and fat-suppressed sagittal images were obtained 33 patients. Twenty these patients underwent surgical débridement and/or primary tendon repair included correlative study. Surgical pathologic reports reviewed to location gross characteristics tissue.Findings at MR correlated with findings...

Treatment of chronic, refractory biceps tendinitis remains controversial. The authors sought to evaluate clinical and functional outcomes arthroscopic release the long head tendon.In specific cases tendinitis, site-specific tendon may yield relief pain symptoms.Case series; Level evidence, 4.Fifty-four patients diagnosed with underwent as an isolated procedure or part a concomitant shoulder over 2-year period. Patients were not excluded for abnormality, including degenerative joint disease,...

We evaluated the use of beach-chair, or sitting, position for arthroscopic shoulder surgery in 50 consecutive patients. Routine arthroscopy, subacromial decompression, and stabilizations were performed, with no complications. The advantages this include ease setup, lack brachial plexus strain because traction is used, excellent intraarticular visualization all types procedures, conversion to open approach if needed. positioning technique described.

We performed a retrospective study of knee joint infections after arthroscopic anterior cruciate ligament reconstruction at our institution. Two thousand five hundred reconstructions were between 1988 and 1993. Seven (0.3%) patients experienced postoperative deep the knee. All using arthroscopically assisted techniques. Six (86%) these had concomitant open procedures performed, including meniscal repair, posterolateral corner reconstruction, medial collateral reconstruction. Four acute (< 2...

PURPOSE: To prospectively assess the accuracy of unenhanced magnetic resonance (MR) imaging in detection and localization labral injuries. MATERIALS AND METHODS: One hundred three patients with clinically suspected shoulder injuries were examined MR imaging. A combination gradient-echo high-resolution fast-spin-echo axial pulse sequences used. Surgical correlation was obtained all patients. RESULTS: At surgery, 37 torn anterior, 36 superior, 19 posterior identified. The sensitivity for these...

We describe and characterize a nanostructured metallic photonic crystal metamaterial which is magnetically active in the near-infrared region of spectrum. The periodic array modified split-ring resonator structures numerically demonstrated to have negative effective permeability at telecommunications wavelengths. Local electric fields structure can be many orders magnitude larger than free space thus allowing for enhanced nonlinear effects. derived an expression change resonance frequency...

Although the semitendinosus and gracilis tendons have long been used in ligamentous reconstruction procedures of knee, their anatomic relationships not explicitly detailed. Therefore, cadaveric dissections were performed on fresh-frozen adult knees to examine these relationships. Several key points are useful harvest tendons. Their conjoined insertion site is medial distal tibial tubercle. They become distinct structures at a point that farther slightly proximal. Tendon facilitated by...

Fifteen patients noted at surgery to have an isolated defect in the rotator interval and no other pathologic abnormality underwent closure of as procedure for recurrent instability symptoms. Intraoperative assessment each these shoulders after demonstrated adequate stability, stabilization procedures were performed. The average age was 24 years, 10 15 women. Examination under anesthesia revealed increased inferior translation all patients, illustrated by least a 1+ sulcus sign. averaged 2.75...

It has been assumed that a robust vascular response at the tendon to bone interface during rotator cuff repairs is an integral part healing process. There are few studies have explored this in in-vivo prospective fashion.To prospectively characterize and anatomical patterns repaired tendons using Power Doppler sonography double-blinded fashion.Case control study; Level of evidence, 3.Fifty patients undergoing repair were enrolled: 28 mini-open, 14 open, 8 arthroscopic repairs; 20 controls....

Revision anterior cruciate ligament surgery remains challenging.To analyze the authors' experience with revision and determine association between stability functional results.Case series; Level of evidence, 4.Between 1991 2002, 95 102 patients who underwent reconstruction at institution met criteria for inclusion in study. Of those, 63 (66%) returned complete clinical radiologic evaluation (mean follow-up, 72.7 months) formed study group. Subjective focused on return to sports, arthritic...
