Summary
Open-door laminoplasty can lead to loss of cervical lordosis. Preserving uppermost facet joints is crucial to prevent postoperative kyphotic deformity after this spine surgery.
Area of Science:
- Spine surgery
- Orthopedic surgery
- Neurosurgery
Background:
- Degenerative cervical stenosis often requires surgical intervention.
- Open-door laminoplasty is a common surgical technique for cervical stenosis.
- Assessing postoperative cervical sagittal alignment is critical.
Purpose of the Study:
- To evaluate cervical sagittal alignment changes after open-door laminoplasty.
- To identify risk factors for postoperative kyphotic deformity.
- To explore strategies for preventing kyphotic changes.
Main Methods:
- Retrospective review of 78 patients undergoing open-door laminoplasty.
- Radiological assessment of C2-C7 Cobb angles and alignment pre- and post-surgery.
- Analysis of CT scans for lamina fractures and facet joint disturbances.
Main Results:
- Mean cervical lordosis significantly decreased post-surgery (p=0.024).
- Uppermost facet disturbance was the independent risk factor for kyphotic change (OR 4.62, p=0.039).
- C3 involvement and lamina fractures were not independent predictors in multivariate analysis.
Conclusions:
- Postoperative sagittal alignment is affected by cranial surgical complications.
- Uppermost facet disturbance is a novel predictor of lordosis loss.
- Preserving facet joints may reduce postoperative kyphotic drift.

8.1K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:14Prevention of Further Absorption of Poison
1.3K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Preventive healthcare services keep people healthy via frequent check-ups, screening, and counseling. They primarily aid in disease prevention rather than treating an acute or chronic illness. Preventive treatment also keeps individuals productive and energetic, allowing them to work well into their retirement years. Examples of preventive care services include:

Essential infection prevention measures are based on the knowledge of the infection chain, the modes of transmission in healthcare settings, and the use of the best practices in all healthcare settings. Compulsory public reporting of healthcare-associated infection rates is needed to allow individuals and the community to make informed choices regarding selecting a healthcare facility.
