Distal ulna is a crucial part of the distal radio-ulnar joint, providing rotation to the forearm. The fractures of the distal ulna need to be fixed properly and on time to ensure proper movement and stability of the wrist. The Ulna Hook Plate provides stable distal ulna fixation with the help of locking screws and distal hooks that shape the ulna styloid.
A forearm is the portion of the arm situated between the wrist and elbow, that is made of two bones that are relatively parallel to each other, namely radius and ulna.
Forearm fracture refers to the situation in which the bones in the forearm, i.e., the radius and ulna are either broken or cracked. The break or crack could be anywhere across the forearm – near the wrist, in the middle or towards the end of the bones, that is near the elbow.
The surgeon goes through the investigations of the patient, such as X-Ray, MRI and CT/CAT, and counsels the patient and the attendees regarding the procedure and the expected outcomes of the surgery.
The patient is usually made to lie down in supine position, with the arms stretched out completely.
Contouring may not be necessary as the plate is pre-contoured. However, if it is absolutely necessary, contouring may be done using flat-nose pliers.
Based on the requirement and the process followed by the surgeon, the screw is drilled inside the plate using drill bits. The plate is fixed distally using appropriate locking screws.
To treat the prevailing infections and to avoid the postoperative infections, the doctor prescribes antibiotics prior to the surgery. Administering antibiotics also ensures better healing post the surgery.
The surgical incision is made toward the ulnar styloid between the flexor carpi ulnaris and extensor carpi ulnaris tendons.
After exposing and cleaning the fracture, the pointed hooks of the plate are secured around the tip of the ulnar styloid for reference. In case of simple fractures of the ulnar neck, the plate needs to be fixed at the subcutaneous border of the distal ulna.
Fluoroscopic imaging can be used to verify the proper placement of the plate, and other anomalies.
