Background: Spondylolisthesis is prevalent in the general population. Surgical approaches
for symptomatic spondylolisthesis that is refractory to conservative treatment vary. Direct …

The purpose of this biomechanical study was to evaluate knee arthrotomy closure with a
barbed suture in flexion versus extension. 48 porcine knees were randomized into three groups…

Background: Percutaneous endoscopic lumbar discectomy (PELD) via the transforaminal
approach is difficult at L5-S1 in patients presenting with high iliac crests (HIC). The …

Background: Surgical treatment for lumbar degenerative spondylolisthesis has been shown
to provide better long-term outcomes than conservative treatment. However, there is …

Background: Total knee arthroplasty can result in blood loss severe enough to require
postoperative blood transfusions. Minimizing blood loss perioperatively is therefore essential to …

Materials and Methods: PECFD was performed on a patient who had an extruded foraminal
disc herniation at

Many investigations in the literature have studied the migration of photons in fluorescent
and non-fluorescent applications, both in the steady-state and time-resolved, within a tissue-…

In this paper we describe a Monte Carlo simulation for time resolved fluorescence. In the past
information on steady state measurements have been reported. However we feel that a lot …

We read with interest the article ‘‘Using percutaneous endoscopic outside-in technique to
treat selected patients with refractory discogenic low back pain” by Liu et al (1). The authors …

Background/Introduction: Axial low back pain is a major cause of morbidity and disability in
health care. Previous studies have found questionable efficacy for surgery in the absence of …
