Intermediate Results of the Prestige LP Cervical Disc Replacement: Clinical and Radiological Analysis With Minimum Two-Year Follow-up.

Study Design: prospective study.

Objective: present results of Prestige LP artificial cervical disc replacement (ADR).

Summary Of Background Data: motion preservation with ADR can potentially reduce adjacent segment degeneration.

Percutaneous endoscopic discectomy: clinical results and how it affects the quality of life.

Study Design: Prospective study

Objective: To determine the clinical outcomes and the effect on quality of life of patients with endoscopic discectomy.

Summary Of Background Data: Percutaneous endoscopic discectomy is a relatively new technique. Very few studies have reported the clinical outcome of percutaneous endoscopic discectomy in terms of quality of life and return to the work.

Percutaneous endoscopic lumbar discectomy: clinical and quality of life outcomes with a minimum 2 year follow-up.

Background: Percutaneous endoscopic lumbar discectomy is a relatively new technique. Very few studies have reported the clinical outcome of percutaneous endoscopic discectomy in terms of quality of life and return to work.

Method: 55 patients with percutaneous endoscopic lumbar discectomy done from 2002 to 2006 had their clinical outcomes reviewed in terms of the North American Spine Score (NASS), Medical Outcomes Study Short Form-36 scores (SF-36) and Pain Visual Analogue Scale (VAS) and return to work.

Perioperative outcomes of anterior lumbar surgery in obese versus non-obese patients.

Background Context: Anterior lumbar surgery is a common procedure for anterior lumbar interbody fusion and disc replacement but the impact of obesity on this procedure has not been determined.

Purpose: To assess the perioperative outcomes of anterior retroperitoneal lumbar surgery in obese versus non-obese patients.

Study Design/setting: Prospective review of patients with anterior retroperitoneal lumbar disc procedures

Patient Sample: Seventy-four patients with anterior retroperitoneal lumbar disc procedures performed were evaluated.

Clinical and radiological outcomes of minimally invasive versus open transforaminal lumbar interbody fusion.

Study Design: Prospective study.

Objective: Comparison of clinical and radiologic outcomes of minimally invasive (MIS) versus Open transforaminal lumbar interbody fusion (TLIF).

Summary Of Background Data: Open TLIF has been performed for many years with good results.

Effect of intervertebral disc height on postoperative motion and clinical outcomes after Prodisc-C cervical disc replacement.

Background Context: Cervical total disc replacement (TDR) is an emerging technology. However, the factors that influence postoperative range of motion (ROM) and patient satisfaction are not fully understood.

Purpose: To evaluate the influence of pre- and postoperative disc height on postoperative motion and clinical outcomes.

Vertebral artery injury in cervical spine surgery: anatomical considerations, management, and preventive measures.

Background Context: Vertebral artery (VA) injury can be a catastrophic iatrogenic complication of cervical spine surgery. Although the incidence is rare, it has serious consequences including fistulas, pseudoaneurysm, cerebral ischemia, and death. It is therefore imperative to be familiar with the anatomy and the instrumentation techniques when performing anterior or posterior cervical spine surgeries.

Polyurethane grafts: a viable alternative for dialysis arteriovenous access?

Polyurethane grafts, promoted for their self-sealing properties and low complication rates, were recently introduced for hemodialysis access. We review our experience with this graft material to determine its complication and patency rates. Between January 1995 and December 1999, 118 patients, 75 female and 43 male, with a mean age of 51 years, had a total of 163 polyurethane arteriovenous grafts inserted.
