Short-term Clinical Outcomes of Hemiarthroplasty With Concentric Glenoid Reaming: The Ream and Run Procedure.

The purpose of this study was to evaluate the short-term clinical and radiographic outcomes of humeral hemiarthroplasty and concentric glenoid reaming ("ream and run" procedure) and to compare the outcomes with those of total shoulder arthroplasty (TSA) for glenohumeral arthritis. Patients with glenohumeral arthritis who underwent the ream and run procedure with a minimum follow-up of 2 years were retrospectively reviewed. The primary outcome was revision to TSA.

Short-term clinical outcome of an anatomic short-stem humeral component in total shoulder arthroplasty.

Background: Short-stem press-fit humeral components have recently been developed in an effort to preserve bone in total shoulder arthroplasty (TSA), but few studies have reported outcomes of these devices. The purpose of this study was to evaluate the short-term clinical outcomes of an anatomic short-stem humeral component in TSA. We hypothesized that the implant would lead to significant functional improvement with low rates of radiographic loosening.

Diagnosis and Management of the Biceps-Labral Complex.

The long head of the biceps tendon (LHBT) is a common source of pathology. The biceps-labral complex (BLC) is the collective anatomic and clinical features shared by the biceps tendon and the superior labrum. LHBT pathology can be caused by inflammation, instability, or trauma.

Nonsurgical Management of Early-onset Scoliosis.

Early-onset scoliosis is potentially fatal if left untreated. Although surgical management with growing instrumentation may be necessary, this is not a panacea and is associated with high complication rates. Recent evidence has demonstrated that nonsurgical treatment can be an effective early management strategy in delaying or even precluding the need for surgery, especially surgery with growing instrumentation.

A role for ATP-sensitive potassium channels in male sexual behavior.

ATP-sensitive potassium (K(+)(ATP)) channels regulate cell excitability and are expressed in steroid-responsive brain regions involved in sexual behavior, such as the preoptic area (POA) and medial basal hypothalamus (MBH). We hypothesized that K(+)(ATP) channels serve as a mechanism by which testosterone can control the electrical activity of neurons and consequently elicit male sexual responsiveness. RT-PCR analysis indicated that castration induces, while testosterone inhibits, mRNA expression of the K(+)(ATP) channel subunit Kir6.
