Official Description

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

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Percutaneous skeletal fixation of a humeral epicondylar fracture, whether medial or lateral, is a minimally invasive surgical procedure aimed at stabilizing fractures located at the distal end of the humerus. The epicondyles are bony protrusions on the humerus that serve as attachment points for muscles and ligaments. Fractures of these areas are classified as extra-articular, meaning they do not extend into the joint space, and can significantly impact the function of the elbow and forearm. The procedure begins with a thorough assessment, including obtaining separate radiographs to confirm the presence and extent of the fracture. A neurovascular examination is also conducted to ensure that the surrounding nerves and blood vessels are intact, which is crucial for preventing complications. Once the fracture is confirmed, the fragments are manually manipulated back into their proper anatomical positions. This manipulation is critical for ensuring optimal healing and function post-surgery. The ulnar nerve, which runs close to the medial epicondyle, is carefully located and protected during the procedure, sometimes necessitating a small incision to facilitate this. Following the reduction of the fracture, percutaneous pins or K-wires are inserted to provide stability to the fracture fragments. The use of these fixation devices allows for a less invasive approach, reducing recovery time and minimizing soft tissue damage. The procedure concludes with the application of a long arm cast to immobilize the area and support the healing process.

1. Indications

The procedure of percutaneous skeletal fixation of a humeral epicondylar fracture is indicated for specific conditions related to the fracture of the humerus. The following are the explicitly provided indications for this procedure:

  • Medial Epicondylar Fracture Fractures occurring at the medial epicondyle of the humerus, which may require stabilization to ensure proper healing and function.
  • Lateral Epicondylar Fracture Fractures occurring at the lateral epicondyle of the humerus, necessitating intervention to restore anatomical alignment and stability.
  • Extra-Articular Fractures Fractures that do not extend into the joint space, which can be effectively treated with percutaneous fixation methods.

2. Procedure

The procedure for percutaneous skeletal fixation of a humeral epicondylar fracture involves several critical steps, each designed to ensure the successful stabilization of the fracture:

  • Step 1: Radiographic Confirmation Initially, separate radiographs are obtained to confirm the presence of the epicondylar fracture. This imaging is essential for assessing the fracture's characteristics and planning the subsequent steps of the procedure.
  • Step 2: Neurovascular Examination A thorough neurovascular examination is performed to evaluate the integrity of the nerves and blood vessels surrounding the fracture site. This step is crucial to prevent potential complications during the procedure.
  • Step 3: Manual Reduction The fracture fragments are then manually reduced, meaning they are manipulated back into their proper anatomical alignment. This step is vital for ensuring that the bones heal correctly and maintain their function.
  • Step 4: Ulnar Nerve Protection The ulnar nerve, which is located near the medial epicondyle, is identified and protected. This may involve making a small incision over the ulnar groove to safely move the nerve out of the way during the fixation process.
  • Step 5: Insertion of Pins or K-Wires Following the reduction, percutaneous pins or K-wires are inserted to stabilize the fracture fragments. The pins are positioned on a drill and carefully inserted, with a small incision made in the skin if necessary to facilitate this placement.
  • Step 6: Confirmation of Positioning The correct positioning of the pins and the anatomical reduction of the fracture are confirmed through radiographic imaging. This step ensures that the fracture is adequately stabilized.
  • Step 7: Trimming and Casting The pins are then trimmed but left protruding from the skin to allow for future adjustments if needed. Finally, a long arm cast is applied to immobilize the area and support the healing process.

3. Post-Procedure

After the procedure, patients are typically monitored for any immediate complications. The long arm cast is applied to immobilize the arm and facilitate healing. Patients may be advised on post-operative care, including keeping the cast dry and monitoring for signs of complications such as increased pain, swelling, or changes in sensation. Follow-up appointments are essential to assess the healing process and to determine when the pins can be removed, if necessary. Rehabilitation exercises may also be recommended to restore function and strength to the affected arm once healing has progressed.

22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
