Comparison of central segment expansion with release and split skin grafting in postburn contractures of fingers
Bibliographic record
Abstract
ABSTRACT Introduction: A diverse range of therapeutic methods such as skin grafting, Z-plasty, local flaps, regional flaps, island flaps, and free flaps have been described for the treatment of postburn hand deformities. Central segment expansion (CSE) is a procedure in which the contracture is released in a manner that a well-settled segment of skin is left over the joint, and defects created on either side of the well-settled segment of skin are skin grafted. Materials and Methods: Sixty cases of postburn mild-to-moderate proximal interphalangeal joint contracture of fingers were randomized to either CSE group or release and split skin grafting (RSSG) group and were followed up for 18 months. Results: The mean age of presentation was 11.11 years. The degree of flexion contracture varied from 30° to 100° (mean = 72.6) in the CSE group, whereas it varied from 30° to 90° (mean = 70.33) in the RSSG group. The mean improvement in the range of motion was 68.33° in the CSE group and 57.83° in the RSSG group. The CSE group resulted in significantly lower values of postoperative extensor lag (12.33° vs. 3.33°; P = 0.002). The mean duration of the postoperative splint was 1.1 months in the CSE group versus 3.4 months in the RSSG group ( P = 0.00). The mean total score using the Vancouver Scar Scale for the appearance of graft scar was 4 ± 0.27 in the CSE group, whereas that for the RSSG group was 2.5 ± 0.39 ( P = 0.00). The recurrence in the two groups was comparable. Conclusion: The technique of CSE to release PBC fingers is easy to perform and shows better results than contracture release with split-thickness skin graft. It can be used as an alternative method for coverage of defects created after postburn contracture release

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
