Novel Ultrasound-Guided Radiofrequency Ablation of the Medial Epicondylar Sensory Nerve for Recalcitrant Medial Epicondylosis: A Case-Based Technical Report.

Recalcitrant medial epicondylosis (ME) is a chronic tendinopathy affecting the common flexor-pronator tendon origin which causes significant pain and functional limitations. Recalcitrant ME is difficult to manage with non-surgical treatment options. The medial epicondylar sensory nerve (MEsn) is a small sensory nerve that travels within the medial intermuscular septum to innervate the osseous-tendinous structures of the medial epicondyle.

A novel technique for the fixation of inter-trochantieric hip fractures: A telescoping lag screw.

One-hundred and three patients with intertrochanteric hip fractures as classified by the OTA 2007 system underwent fixation using the telescoping AOS Galileo lag screw system and ES Nail (a long IM nail). Thirty-one patients (76%) were female and ten (24%) were male, with an average age of 75.70 ± 11.

A Simple Dewar/Cryostat for Thermally Equilibrating Samples at Known Temperatures for Accurate Cryogenic Luminescence Measurements.

The design and operation of a simple liquid nitrogen Dewar/cryostat apparatus based upon a small fused silica optical Dewar, a thermocouple assembly, and a CCD spectrograph are described. The experiments for which this Dewar/cryostat is designed require fast sample loading, fast sample freezing, fast alignment of the sample, accurate and stable sample temperatures, and small size and portability of the Dewar/cryostat cryogenic unit. When coupled with the fast data acquisition rates of the CCD spectrograph, this Dewar/cryostat is capable of supporting cryogenic luminescence spectroscopic measurements on luminescent samples at a series of known, stable temperatures in the 77-300 K range.

Complete blood count before and after total hip or knee arthroplasty.

Purpose: To validate our transfusion protocol based on pre- and post-operative complete blood count (CBC) data in patients undergoing primary total hip or knee arthroplasty (THA or TKA).

Methods: Records of 113 men and 205 women aged 32 to 94 (mean, 70) years who underwent primary uncemented THA (n=123) or cemented TKA (n=195) for osteoarthritis by 2 senior surgeons were reviewed. A post-surgical drain was used in 29 THA patients and 74 TKA patients, based on the surgeon's preference.

Recurrent patellar tendon rupture in a patient after intramedullary nailing of the tibia: reconstruction using an Achilles tendon allograft.

Various complications after intramedullary (IM) nailing of the tibia have been reported, the most common of which are anterior knee pain and symptoms similar to patella tendonitis. Complete rupture of the patellar tendon after IM nailing of the tibia has been reported on 2 occasions, in conjunction with predisposing patient factors, such as systemic disease or a proud tibial nail. Patellar tendon ruptures are disabling injuries that can be technically difficult to repair because of the poor quality of remaining tendon tissue, quadriceps muscle atrophy and/or contracture, and scar-tissue formation.
