Background Context: Intraoperative detection of a pedicle wall breach implicitly reduces surgical risk, but the reliability of intraoperative neuromonitoring has been contested. Hydroxyapatite (HA) has been promulgated to increase pedicle screw resistance and negatively influence the accuracy of electromyography.
Purpose: The primary purpose of this experiment is to evaluate the effect of HA on pedicle screw electrical resistance using a controlled laboratory model.
Pedicle morphometry in the upper thoracic spine: limits to safe screw placement in older patients.
Spine (Phila Pa 1976)
November 2002
Article Synopsis
- The study analyzed the dimensions and orientation of upper thoracic vertebrae pedicles in elderly human cadavers to evaluate the feasibility of safe screw fixation.
- The research found that while some pedicles were adequate for screw placement, a significant portion (over 50%) were too small to accommodate standard screw sizes, especially in lower thoracic vertebrae.
- The conclusions emphasize the importance of careful assessment for transpedicular screw placement to avoid complications, especially in patients with smaller pedicles.
Article Synopsis
- For years, spinal surgeons have worked on creating effective single-stage anterior fixation systems for the thoracic and lumbar spine, and early models faced significant issues.
- The AO Anterior Thoracolumbar Locking Plate (ATLP) was developed to address these problems and is made of Commercially Pure titanium, designed for conditions like unstable burst fractures and metastatic tumors between T10 and L5.
- Clinical trials on 25 patients over 38 months showed the ATLP system to be generally safe with some minor complications, such as broken screws, but no broken plates, indicating its effectiveness for anterior spinal column fixation.
Frequency of metastasis to the spine in the population of patients suffering from malignant disease is a significant clinical problem, as these patients present with intractable pain and neurologic impairment. The sequelae of metastatic tumors to the spinal column significantly decrease the quality of the patient's life. With the advent of modern chemotherapeutic regimens in metastatic disease, patients with metastatic tumors are living longer and more productive lives.

In this method, the parietal pleura is detached from the chest wall and retracted with the visceral pleura and its contents. A direct approach to the vertebral bodies is thus achieved without transgression of the intrapleural space.

Demographic variables and preoperative diagnoses were similar between treatment groups.

J Spinal Disord
September 1991
Variable screw placement (VSP) plates and pedicle screw fixation were used to stabilize eleven lumbar neoplasms. Blood loss and complications were comparable to other methods of posterior segmental fixation, although operative times were longer. Fewer levels were fused than for systems using sublaminar hooks or wires, with 8/11 patients treated with two level fixation.
