Outcome of combined nerve and tendon transfer in tetraplegia: a new surgical strategy to restore grasp function
Bibliographic record
Abstract
This study aimed to assess the outcome of supinator to posterior interosseus nerve transfer, followed by tendon transfer, to restore grasp function in patients with mid-to-high-level cervical spine injuries. Fifteen upper limbs in 11 patients with these injuries were included. The outcomes were then compared with a historical control group consisting of 16 upper limbs that received tendon transfers alone. The outcome was assessed using the Canadian occupational performance measure, ability to open the first web space, and grip and pinch strength 12 months after surgery. The Canadian occupational performance measure was similar in both groups, even though the study group had more severe preoperative impairment. The grip strength was significantly lower in the study group, whereas pinch strength was similar between the groups. This study suggests that a combined nerve and tendon transfer in patients with tetraplegia may offer benefits. Level of evidence: III

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.
