Efficacy of automated percutaneous lumbar discectomy for lumbar disc herniation in young male soldiers.

Lumbar disc herniation (LDH) often results in back pain and radicular pain and is frequently treated with minimally invasive non-surgical methods in Korean Armed Forces Hospitals. Automated percutaneous lumbar discectomy (APLD) has been reported to have good clinical outcomes with low complication rates; however, the clinical efficacy of APLD performed in young male soldiers is uncertain. In order to clarify the efficacy of APLD for the treatment of LDH in young male soldiers, we designed a retrospective case-control study to compare patients who received APLD with patients treated with epidural steroid injection (ESI) alone.

Does Proximally Coated Single-Wedge Cementless Stem Work Well in Dorr Type C Femurs? Minimum 10-year Followup.

Background: Total hip arthroplasty (THA) with a proximally coated single-wedge (PSW) cementless stem had been generally considered not to be suitable for Dorr Type C femurs. This study compares the long term outcomes of PSW stem according to the type of proximal femoral geometry.

Materials And Methods: 307 primary THAs in 247 patients were performed with PSW cementless stem and followed up for over 10 years in this retrospective study.

Adhesive capsulitis of the hip.

Purpose: Adhesive capsulitis of the hip (ACH) is not a well-defined disease entity. We evaluated the change in the clinical features of patients whose chief complaint was inability to sit cross-legged on the floor. All patients had painful limitation in hip joint motion.

Adjuvant Teriparatide Therapy for Surgical Treatment of Femoral Fractures; Does It Work?

Purpose: Atypical femoral fracture (AFF), periprosthetic femoral fracture (PPFF) and femoral nonunion (FNU) are recalcitrant challenges for orthopedic surgeons. Teriparatide (TPTD) had been demonstrated to have anabolic effects on bone in various studies. We postulated that adjuvant TPTD after operation would enhance biologic stimulation for bone formation.

Changes of functional outcomes according to the degree of completeness of spinal cord injury.

Objective: To evaluate whether an initial complete impairment of spinal cord injury (SCI) contributes to the functional outcome prediction, we analyzed the relationship between the degree of complete impairment according to the American Spinal Injury Association impairment scale (AIS), the posterior tibial nerve somatosensory evoked potential (PTSEP) and the changes of functional indices.

Methods: Sixty subjects with SCI were studied who received rehabilitative management for over 2 months. The degree of completeness on basis of the initial AIS and PTSEP were evaluated at the beginning of rehabilitation.

Gold nanoparticle-hybridized "nano-sponge" polymer coatings to enhance the reliability and sensitivity of biosensors.

We have created a new functional biosensor coating composed of polyelectrolyte multilayers containing gold nanoparticles. This gold-hybridized polyelectrolyte multilayer film possesses a stable nanoporous structure under physiological conditions. Antibody molecules were successfully conjugated onto the gold nanoparticles within the film.
