distal ulna resection

After the distal ulnar fracture is healed, dislocation of the subtalar joint can cause arthritis of injury. In the distal stage, the fracture of the distal radius of the humerus will affect the development of the tendon, so that the distal end of the ulna is prominent, and the dislocation of the subtalar joint can also occur. All of the above situations can cause obstacles in the function of the joints and wrist joints under the ruler. A simple and effective method is to remove the distal segment of the ulna. Clinically, this operation is mostly used for such diseases and tumors at the distal end of the ulna. Treatment of disease: fracture of the lower third of the ulna and fracture of the lower ankle joint Indication After the distal ulnar fracture is healed, dislocation of the subtalar joint can cause arthritis of injury. In the distal stage, the fracture of the distal radius of the humerus will affect the development of the tendon, so that the distal end of the ulna is prominent, and the dislocation of the subtalar joint can also occur. All of the above situations can cause obstacles in the function of the joints and wrist joints under the ruler. A simple and effective method is to remove the distal segment of the ulna. Clinically, this operation is mostly used for such diseases and tumors at the distal end of the ulna. Surgical procedure 1. Position: The patient is supine, the upper limb is abducted or placed on the chest, and the upper arm is placed with an inflatable tourniquet. 2. Incision, revealed: from the ulnar stem, the skin is cut upward along the outer edge of the ulna, about 5cm long. The incision should not exceed the styloid process to avoid damage to the superficial branch of the ulnar nerve. The fascia and the periosteum of the ulna were cut between the ulnar extension and the flexor tendon, and the periosteum was about 2.5 cm. The periosteum was removed from the distal end of the ulna. 3. Resection of the distal segment of the ulna: a short bevel cut 2.5 cm away from the distal end of the ulna, obliquely facing the ulnar side, so as to prevent the stump from protruding subcutaneously. A number of holes should be drilled in the predetermined ulnar section, and then cut between the holes by chiseling or cutting to avoid splitting of the bone. The distal end of the ulna and the styloid process can be completely removed by clamping the distal end of the fracture and turning it down. Care should be taken to avoid damage to surrounding tissues and the movements, veins and nerves located in front of the ulna. The site of bone resection should not be too high. In order to avoid cutting off the stop point of the anterior muscle, it causes an obstacle to the rotation function of the forearm. 4. Stitching: The residual periosteum at the distal end of the ulna is contracted into a strip shape to fix the ulnar stump to prevent the formation of new bone, and then suture layer by layer.
