Outcome of Spine Fixation for Unstable Fractures at Dorslumbar Junction Including Fractured Vertebrae in Pedicular Screw Fixation
Bibliographic record
Abstract
Objective: In the present study, the researchers want to establish the outcome of spine fixation for unstable fractures at the dorsolumbar junction, including fractured vertebrae, while using pedicular screw fixation techniques. Study Design: Prospective study Place and Duration: The study was conducted at Orthopaedics Department, Hayatabad Medical Complex, Peshawar and Neurosurgery Department, Frontier Medical and Dental College, Abbottabad for the duration of six months from May 2021 to October 2021. Methods: There were hundred and nineteen patients of both genders had unstable fracture at dorslumbar junction. Patients were aged between 20-55 years. Transpedicular screws were used to secure the fractured vertebra. Both radiographic and clinical assessments of back pain and impairment were conducted using the Visual Analogue Scale (VAS) and the Oswestry Disability Index (ODI) to evaluate patients (ODI). Before surgery, shortly after surgery, and eight months afterwards, all of these data were assessed. SPSS 23.0 version was used to analyze complete data. Results: Mean age of the patients was 33.5±5.42 years. 85 (71.4%) cases were males and 34 (28.6%) patients were females. Falling from the height was the most common reason found in 60 (50.4%) cases followed by road traffic accident 45 (37.8%) cases and 14 (11.8%) were others. L1 fractures were majority found in 67 (56.3%) cases followed by L2 in 40 (33.6%) cases. Post-operatively, we found significantly improvement in Cobb angle, anterior vertebral height, posterior vertebral height and sagittal index with p value <0.05. Oswestry disability index (ODI) was improved to 41.13±19.42% from 70.6±16.43%. Mean pain score (VAS) was reduced to 1.01±5.23. Post-operatively only 7 (5.9%) patients had complications. Conclusion: Our patients who had transpedicular screw fixation, which included fixing the broken vertebrae, had outstanding radiological and clinical outcomes. Treatment of the fractured vertebra in transpedicular screw fixation of dorsolumbar spine fractures is, thus, highly recommended.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
