Purpose: To evaluate motor grading and hand functional outcomes of restoring tetraplegic hands using single-stage multiple nerve transfers, including double nerve transfers, for finger flexion.
Methods: Patients with tetraplegia who had single-stage multiple nerve transfers between January 2016 and December 2021 were included in the study. We evaluated the patients using muscle grading, the International Spinal Cord Injury Upper Extremity basic data set, the Toronto Rehabilitation Institute-Hand Function Test, the Spinal Cord Independent Measure III, and the Spinal Cord Ability Ruler.
Background: Patient-reported outcome measures (PROMs) were developed to examine patients' perceptions of functional health. Most studies compare the responsiveness of each type of questionnaire. However, reports of patient preferences among PROMs commonly used with patients with hand/wrist injuries or disorders are limited.

The authors investigated the vascular supply of the proximal fibula, including skin perforators, for suitability in creating an osteocutaneous flap.
Methods: Twenty fresh cadaveric knees were studied using computed tomographic angiography combined with anatomical dissection.
The effects of soft tissue damage and ulnar angulation deformity on radial head instability in Monteggia fractures are unclear. We tested the hypothesis that radial head instability correlates with the magnitude of ulnar angular deformity and the degree of proximal forearm soft tissue injury in Bado type I Monteggia fractures.We performed a biomechanical study in 6 fresh-frozen cadaveric upper extremities.

Methods: Double nerve transfer was conducted in 22 cadaver upper extremities. Donor nerves were the brachialis branch of the musculocutaneous nerve and the extensor carpi radialis brevis (ECRB) branches of the radial nerve.
Purpose: Certain distal ulna fractures may contribute to distal radioulnar joint (DRUJ) instability. We hypothesized that residual distal ulna translation could affect DRUJ stability by slackening the distal interosseous membrane (DIOM). We aimed to test this hypothesis in a cadaver model.

Background: The descending genicular artery supplies skin, muscle, tendon, and bone structures in the medial knee area. Three types of skin perforator including musculocutaneous perforators through the vastus medialis (descending genicular artery perforator (DGAP)-vm), direct cutaneous perforators (DGAP), and saphenous artery perforators (SAP) can be elevated for the skin flap component.
Methods: This study included a prospective cohort of all patients in whom a descending genicular artery free flap was attempted in our center since January 2009.
Background: Most minor hand operations can be performed with local anesthesia and tourniquet. Some literature supports this concept based on the believe that the "patient can tolerate it". Nowadays, the wide-awake technique with epinephrine- contained lidocaine is safe.

Objective: To compare the pull-out strength between degrees of Kirschner wire fixation (0° and 30°) and the effect of filling an insulin syringe with polymer
Material And Method: Pull-out strength was compared between a syringe externalfixator and a bone or plastic tube model. Fifty-two plastic tube models and 20 dry phalangeal bones were included The syringe external fixator was attached via two Kirschner wires.
Background: With increasing use of free vascular flaps of the saphenous artery and descending genicular artery, the authors investigated the anatomical variations in cadavers.
Methods: Thirty-one fresh cadaveric thighs were studied by anatomical dissection. The perforators and their source arteries were skeletonized along their courses to the superficial femoral artery and measured.
We report on 45 pedicle perforator flaps without harvesting major vessels in limb reconstruction. Of our patients, 25 had major vessel injury resulting from their initial injury. In the upper extremities, there were 13 posterior interosseous artery perforator flaps, four ulnar artery perforator flaps and three radial artery perforator flaps.

The descending branch arose from the lateral circumflex femoral artery in 38 of the dissections, and the mean diameter at its origin was 3.0mm (range, 2.

Methods: The DRC ligaments were harvested from 20 wrists of 10 fresh cadavers with an average age of 75.6 years within 12 to 18 hours of death.
