Study Design:
This was a prospective study of 50 patients of thoracolumbar fracture dislocation treated at a single institution with short-segment fixation with the inclusion of fracture level.
Purpose:
To assess the outcomes of including the fracture level in short-segment fixation for thoracolumbar fracture dislocation.
Overview Of Literature:
Traditionally, thoracolumbar fracture dislocation is treated with long-segment posterior fixation. However, to save motion segments, short-segment fixation has been used instead in many cases of thoracolumbar trauma.
Methods:
In this study, 50 patients with thoracolumbar fracture dislocation were treated with short-segment fixation with inclusion of the fracture level; patients with pathological fractures or with a McCormack load-sharing score >6 were excluded. The 50 patients were prospectively followed for at least 1 year. The duration of surgery, blood loss, and complications were noted. The Visual Analog Scale (VAS) score was used to measure pain, and the American Spinal Injury Association (ASIA) scale was used to determine the neurological status at follow-up. Preoperative, immediate postoperative, and final follow-up X-rays were used to measure the kyphotic angle using Cobb's method.
Results:
The mean age of our patients was 33.4 years, and the male:female ratio was 1.9:1. The mean follow-up period was 18.4 months (range, 12-23 months). Injuries were mainly at the thoracolumbar junction area (T11-L2, 41 cases, 82%). The average duration of surgery was 94.6 minutes, and the average blood loss was 394.8 mL. Postoperative infection occurred in two cases and implant failure in one case. The kyphosis angle values were as follows: average preoperative, 26.80°±14.50°; immediate postoperative, 4.30°±8.70°; and final follow-up, 5.50°±110°. The ASIA scale and VAS score at final follow-up showed improvement.
Conclusions:
Inclusion of the fracture level in short-segment fixation for thoracolumbar fracture dislocation (McCormack load-sharing score ≤6) gives good kyphosis correction and correction maintenance. It can also obviate the need for traditional long-segment fixation.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
