partial distal ulna amputation

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 diseases: ulnar shaft fractures Indication It is mainly used for forearm gyroscopic movement caused by anterior muscle contracture and distal ulnar joint injury. Contraindications 1. The infection after the local injury has not been eliminated. 2. Injury refers to the passive flexion and extension of each joint. Preoperative preparation 1. Edema and inflammation of the limbs and wards, even if mild, should be actively treated, so that it completely disappears after 2 to 3 months of surgery. 2. Local large and hard scars should be removed first and the flaps should be repaired to ensure a good blood supply and a soft loose tissue bed around the tendons. 3. Before the tendon is sutured, the joint stiffness of the dominant tendon should be treated first, and the physical therapy and active and passive exercise should be given to restore the greater activity, so that the effect of the tendon suture can be operated and received. 4. The suture material should be selected from the varieties with small reaction, large pulling force and smooth surface. Generally, soft stainless steel wire with a diameter of 0.25 to 0.30 mm is preferred, and is mostly used for drawing steel wire stitching. Tendons with small or small diameters can be sutured with Nilon monofilament. Filament thread suture has a certain degree of tissue reaction, mostly used for Bunnell burial suture, but the silk thread must be able to withstand 1 to 1.5 kg of tensile force. 5. Prepare a slender straight round needle for suturing the tendon. Surgical procedure At the proximal edge of the anterior muscle, the periosteum of the ulna was cut open in a circular shape, and another circular incision was made 3 to 6 cm proximal to it. Use a chainsaw or wire saw to remove the ulnar segment from the incision periosteum. The ulnar segment is removed to form a bone defect (an ulnar pseudoarticular). The osteophytes are trimmed with osteophytes and the broken periosteum is removed. Relax the tourniquet and suture the wound layer by layer after the bleeding stops. No external fixation is required, and the activity can be started after the postoperative pain is alleviated. complication Suppurative infection, infected wounds have pain, redness, tenderness, purulent secretions, etc., body temperature can be increased and neutrophils can be increased. Closed wounds may also be associated with various infections, such as post-injury aspiration, airway endocrine retention, and atelectasis secondary lung infections. Tetanus or gas gangrene may also occur after the injury, and the consequences are quite serious.
