Differential Agnostic Effect Size Analysis of Lumbar Stenosis Surgeries.

Study Design: A meta-analysis of 89 randomized prospective, prospective, and retrospective studies on spinal endoscopic surgery outcomes.

Objective: The study aimed to provide familiar Oswestry Disability Index (ODI), visual analog scale (VAS) back, and VAS leg effect size (ES) data following endoscopic decompression for sciatica-type back and leg pain due to lumbar herniated disc, foraminal, or lateral recess spinal stenosis.

Background: Higher-grade objective clinical outcome ES data are more suitable than lower-grade clinical evidence, including cross-sectional retrospective study outcomes or expert opinion to underpin the ongoing debate on whether or not to replace some of the traditional open and with other forms of minimally invasive spinal decompression surgeries such as the endoscopic technique.

Anterior Cervical Discectomy and Fusion With a No-Profile Integrated Fixation Allograft Device: An In Vitro Biomechanical Analysis and Clinical Case Series.

Background: No-profile anterior cervical discectomy and fusion (ACDF) devices are commonplace in spinal surgery. Contained within the intervertebral margins, these devices diminish risks associated with anterior cervical plating, while also marginalizing cage migration and subsidence. However, these devices have been limited in their scope of implant material.

Prosthetic design of reverse shoulder arthroplasty contributes to scapular notching and instability.

Aim: To evaluate whether implant design, glenoid positioning, and other factors influenced instability and scapular notching in reverse total shoulder arthroplasty.

Methods: We retrospectively reviewed records of patients who had undergone reverse total shoulder arthroplasty by the senior author from July 2004 through October 2011 and who had at least 24 mo of follow-up. The 58 patients who met the criteria had 65 arthroplasties: 18 with a Grammont-type prosthesis (Grammont group) and 47 with a lateral-based prosthesis (lateral-design group).

Local versus distal transplantation of human neural stem cells following chronic spinal cord injury.

Background Context: Previous studies have demonstrated functional recovery of rats with spinal cord contusions after transplantation of neural stem cells adjacent to the site of acute injury.

Purpose: The purpose of the study was to determine if the local or distal injection of neural stem cells can cause functional difference in recovery after chronic spinal cord injury.

Study Design/setting: Twenty-four adult female Long-Evans hooded rats were randomized into four groups, with six animals in each group: two experimental and two control groups.

Gunshot femoral fractures with vascular injury: a retrospective analysis.

Objective: To retrospectively investigate the experience at one urban level one trauma center with gunshot femoral fractures with vascular injury and to examine the implication of surgical sequence with regards to short-term complications and ischaemia time.

Methods: We performed a retrospective study of 24 patients treated at an urban level one trauma center over a 10-year period with low velocity gunshot wounds resulting in femur fractures and major vascular injury. Data were stratified according to sequence of surgical intervention.

Rehabilitation after anteromedialization of the tibial tuberosity.

Various surgical procedures are currently being used to treat symptomatic patellar instability. Distal bony realignment techniques attempt to correct malalignment by shifting the site of insertion of the patellar tendon. Tibial tuberosity anteromedialization, also known as the Fulkerson osteotomy, is a process in which the tuberosity is transferred anteriorly and medially.
