Official Description

Percutaneous skeletal fixation of humeral condylar fracture, medial or lateral, with manipulation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Percutaneous skeletal fixation of a medial or lateral condylar fracture of the humerus is a surgical procedure aimed at stabilizing fractures located at the distal end of the humerus, specifically at the condyles. The humerus, which is the long bone of the upper arm, has two prominent projections known as the medial and lateral epicondyles. A condylar fracture refers to a break that occurs at these projections, which can lead to the separation of the medial metaphysis and epicondyle from the main body of the humerus. These types of fractures can also extend into the trochlea, affecting the articular surface of the joint. This procedure is indicated when a fracture is present in either the medial or lateral condyle, but not both simultaneously. Prior to the fixation, imaging studies, such as radiographs, are performed to confirm the presence and extent of the fracture. A thorough neurovascular examination is conducted to assess the integrity of the nerves and blood vessels surrounding the injury site. The procedure involves manually manipulating the fracture fragments back into their correct anatomical positions, followed by the insertion of percutaneous pins or K-wires to stabilize the fragments. The use of imaging is critical throughout the procedure to ensure proper alignment and fixation of the fracture, ultimately leading to the application of a long arm cast to support the healing process.

1. Indications

The procedure is indicated for the treatment of specific types of fractures in the distal humerus, particularly:

  • Medial Condylar Fracture A fracture occurring at the medial condyle of the humerus.
  • Lateral Condylar Fracture A fracture occurring at the lateral condyle of the humerus.

2. Procedure

The procedure involves several critical steps to ensure proper fixation of the fracture:

  • Step 1: Radiographic Confirmation Initially, separate radiographs are obtained to confirm the presence of a fracture in either the medial or lateral condyle of the humerus. This imaging is essential for accurate diagnosis and treatment planning.
  • Step 2: Neurovascular Examination A thorough neurovascular examination is performed to assess the integrity of the nerves and blood vessels in the area surrounding the fracture. This step is crucial to prevent complications during the procedure.
  • Step 3: Manual Reduction The fracture fragments are manually reduced, meaning they are carefully manipulated back into their proper anatomical alignment. This step is vital for restoring the normal function of the elbow joint.
  • Step 4: Additional Radiographic Confirmation After manual reduction, additional radiographs are obtained to confirm that the fracture fragments are correctly aligned and stabilized.
  • Step 5: Ulnar Nerve Protection The ulnar nerve is located and protected during the procedure. This may involve making a small incision over the ulnar groove to ensure the nerve is safely held out of the way during fixation.
  • Step 6: Insertion of Pins or K-Wires Percutaneous pins or K-wires are then inserted to stabilize the fracture fragments. A small incision may be made in the skin to facilitate the placement of these fixation devices. Typically, two pins are used, with one inserted laterally and the other medially, although variations in pin configuration may occur based on the specific fracture.
  • Step 7: Radiographic Confirmation of Fixation The correct positioning of the pins and the anatomic reduction of the fracture are confirmed through radiographic imaging, ensuring that the fixation is secure.
  • Step 8: Trimming and Casting The pins are trimmed but left protruding from the skin to allow for future adjustments if necessary. Finally, a long arm cast is applied to immobilize the arm and support the healing process.

3. Post-Procedure

Post-procedure care involves monitoring the patient for any signs of complications, ensuring that the cast remains intact, and providing instructions for care at home. Patients are typically advised on how to manage pain and swelling, as well as the importance of keeping the cast dry. Follow-up appointments are necessary to assess healing and to determine if any adjustments to the pins or K-wires are needed. The duration of immobilization in the cast will depend on the specific nature of the fracture and the patient's healing progress.
