Using suture anchors for cervical laminoplasty: a reliable, safe, and simple technique.

Cervical spondylomyelopathy from spinal stenosis is a debilitating disease that often progresses with neurologic deficits in the upper and lower extremities. Spinal stenosis may be treated operatively with expansive open-door laminoplasty. We describe the technique of laminoplasty using suture anchors.

Treatment of malignant tumors of the proximal humerus with allograft-prosthesis composite reconstruction.

Malignant tumors of the proximal humerus are challenging to treat. Reconstruction with a metallic implant or allograft is the most common method, but each has known risks and frequent complications. Allograft-prosthesis composite reconstruction has not been widely used and may avoid problems posed by metal prostheses or allografts used alone.

Deficits in shoulder function and general health associated with sixteen common shoulder diagnoses: a study of 2674 patients.

The purpose of this study is to define the self-assessed deficits in function and general health perceived by a large cohort of patients with common shoulder diagnoses. For a 10-year period, all new shoulder patients presenting to the senior author were characterized by diagnosis, age, gender, and self-assessed shoulder function and general health status. This report concerns the 2674 patients having 1 of the 16 most prevalent diagnoses.

Characterizing the effect of diagnosis on presenting deficits and outcomes after total shoulder arthroplasty.

This study compared self-assessed deficits in comfort, function, and health status before and after total shoulder arthroplasty for 4 different diagnoses: degenerative joint disease (DJD), secondary DJD (2 degrees DJD), rheumatoid arthritis (RA), and capsulorrhaphy arthropathy (CA). Deficits were assessed by the Simple Shoulder Test and Short Form 36 (SF-36) questionnaires. There was a significant difference among diagnoses for preoperative and postoperative functional deficits.

Patient functional self-assessment in late glenoid component failure at three to eleven years after total shoulder arthroplasty.

Failure of the glenoid component is the most common indication for late revision of a total shoulder arthroplasty (TSA). This is the first study to characterize the deterioration in patient self-assessment of shoulder function occurring with glenoid component failure at times remote from the index surgery. Of 115 total shoulders, 11 had revision by the original surgeon for isolated glenoid loosening.

Open rotator cuff repair without acromioplasty.

Background: In most clinical reports on rotator cuff repair, acromioplasty was done as part of the procedure. In this prospective study, we evaluated the hypothesis that rotator cuff repair without acromioplasty would result in a substantial improvement in shoulder comfort and function.

Methods: Ninety-six consecutive primary repairs of full-thickness tears of the rotator cuff were performed through a deltoid-muscle-splitting incision that preserved the integrity of the coracoacromial arch and the deltoid insertion.

Healing of reamed glenoid bone articulating with a metal humeral hemiarthroplasty: a canine model.

This study characterizes the healing response of the glenoid after spherical reaming and prosthetic humeral head replacement in a canine model of glenohumeral hemiarthroplasty. The right glenoid of twelve skeletally mature female dogs was reamed to a uniform radius of curvature, removing all cartilage down to bleeding subchondral bone. The glenoid was not resurfaced.

Glenohumeral arthritis and its management.

Glenohumeral arthritis has many different etiologies, including osteo-arthritis, secondary degenerative joint disease, rheumatoid arthritis,avascular necrosis, cuff tear arthropathy, and capsulorrhaphy arthropathy. Each of these diagnoses may have different underlying pathoanatomy and pathomechanics. The treating physician must recognize how these characteristics impair shoulder function so that the prescribed course of treatment addresses the root causes of shoulder dysfunction.

Effects of basic fibroblast growth factor on the retinal degeneration of the mi(vit)/mi(vit) (vitiligo) mouse: a morphologic and electrophysiologic study.

Basic fibroblast growth factor (bFGF) has been shown to rescue dying photoreceptor cells in the RCS rat, a model with a genetic defect of the RPE that impairs outer segment phagocytosis. The purpose of the present study was to determine whether intravitreal injection of bFGF would have a similar effect on photoreceptor cell death in the vitiligo (C57BL/6-mi(vit)/mi(vit)) mouse. This mutant mouse loses photoreceptor cells slowly over many months.
