Video Transcription
Demonstrating palmaris longus, flexor carpi radialis, the interval between the radial artery and the flexor carpi radialis, the incision marked out with the scaphoid waste lying approximately at the level of the wrist crease. Through the subcutaneous tissue to the sheath of the FCR. The FCR tendon is then retracted ulnarly to go through the floor of the sheath of the FCR median nerve. The radial scaphocapotate ligament, sharply incised to develop flaps. Just a little extension of the scapho-trapezial joint. Flaps elevated radial and ulnar, and the volar foot process of the trapezium, which will be removed with a ronger to allow targeting of the screw, so the proximal, excuse me, the distal pole of the scaphoid, and then the overlying volar foot process of the trapezium which can prevent proper targeting. Now with the scaphoid exposed, we can, in the setting of a fracture, insert two F4-5K wires. So through the floor, the radial scaphoid capitate ligament divided, radial ulnar flaps developed, scapho-trapezial joint, radial carpal joint. Two K wires can be inserted to use as joysticks to, for manipulating, for manipulative reduction. And then we can load the cannulated wire.
Video Summary
In this video, the demonstrator discusses the anatomy of the palmaris longus and flexor carpi radialis muscles, as well as the interval between the radial artery and flexor carpi radialis. They mark out an incision at the level of the wrist crease and make their way through the tissue to the sheath of the flexor carpi radialis. The FCR tendon is then retracted to expose the floor of the sheath and the median nerve. The radial scaphocapotate ligament is incised, allowing for the elevation of flaps. The volar foot process of the trapezium is removed, revealing the distal pole of the scaphoid. Two F4-5K wires are inserted to aid in manipulative reduction and a cannulated wire is loaded. No credits are mentioned in the transcript.
