Fixation of inter trochanteric fractures by various types of cephallomedullary nails: A tertiary care center review
Bibliographic record
Abstract
Background: Trochanteric fractures are of intense interest globally, as they are frequently operated. They are fixed commonly either by Dynamic hip screw (DHS) or proximal femoral nail (PFN). The mechanical strength of the nail and less invasive procedure has made the procedure preferable. The different types of nails that are commonly used are, Proximal Femoral Nail (PFN), Proximal Femoral Nail Antirotation2 (PFN A2), Hip fracture nail (HFN) and Halifax nail. The aim of the study was to review intertrochanteric fractures fixation by various types of cephallo medullary nails. Methods:A retrospective study was conducted at Orthopaedics department of IGIMS, Patna, India. Records of 51 cases operated during 2015 to 2018 which had completed at least one year of follow up and fulfilled the inclusion and exclusion criteria were evaluated. All had been treated using various types of proximal femoral nail for Trochanteric fractures of femur. A radiological assessment was made with serial X-rays.Results:Most of the patients were between 70-80 years of age. PFN was used in 22, PFNA2 in 24, HFN in 3 and Halifax in only 2 patients. A statistically significant difference (p

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.
