Interventional Mapping Table of SETS Scoping Review with Expert Insights

Category	Results	Expert Insights
Primary outcomes	Subjectives: -Patient-reported outcomes (DASH, QuickDASH) -Return of function (patient’s perception) Objectives: -MRC of FDI and ADM muscles -Rosen score -Return of intrinsic muscle function (clinician assessment)	-Assess intrinsic function in forearm pronation -FDI evaluation -Tinel sign in short-term assessment
Secondary outcomes	Subjectives: -Restoration of clawing deformity (patient’s perception) -Pain assessment -Therapy adherence Objectives: -Electrodiagnosis -Recovery time -Pinch and grip strength -Hand abduction -Neurological examination
Timing of assessment	-Short-term -Medium-term -Long-term	-Dependent on individual patient characteristics
Donor site morbidity and complications	-No donor site morbidity and complications -Minor complications -Specific complications which are not indicative issue with the SETS	-Potential risks associated with surgical precision (incorrect nerve detection)
Factors associated with recovery	-Preoperative dysfunction duration -Patient-specific variables -The severity and anatomical level of the nerve lesion -The surgical techniques -Rehabilitation adherence	-Location of the nerve transfer (proximal to the wrist crease to avoid tension during the repair) -Concurrent decompression at ulnar Guyon canal -Microscopic surgery and delicate suture preference -End-to-end technique for the most severe cases
Indication for surgery	-Severe cubital tunnel syndrome -High ulnar nerve surgery -Normal PQ presence by EMG	-Intraoperative PQ assessment -Electrodiagnostic protocol consideration

ADM, abductor digiti minimi; FDI, first dorsal interosseous; MRC, Medical Research Council; PQ, pronator quadratus; QuickDASH, Disabilities of the Arm, Shoulder, and Hand; SETS, supercharged end-to-side.
