Official Description

Arthroplasty, elbow; with distal humeral prosthetic replacement

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Arthroplasty of the elbow with distal humeral prosthetic replacement is a surgical procedure aimed at addressing severe joint damage or dysfunction in the elbow. This procedure involves the replacement of the distal end of the humerus with a prosthetic implant, which is designed to restore function and alleviate pain. The surgery typically begins with a skin incision made over the elbow joint, either on the medial or lateral side of the olecranon process, allowing access to the joint. During the operation, careful dissection of the soft tissues is performed, with particular attention given to the ulnar nerve, which is identified and protected to prevent injury. The lateral epicondyle of the humerus is exposed, and the surgical team navigates through the surrounding structures, including the anconeus and flexor carpi ulnaris muscles, to access the elbow joint. The procedure involves meticulous steps to ensure proper alignment and fit of the prosthetic implant, including the reaming of the humeral canal and the placement of a trial implant to verify the dimensions before the final implant is secured with bone cement. Post-surgery, the elbow is stabilized, and the arm is placed in a splint to facilitate healing. This procedure is indicated for patients with significant elbow joint degeneration, often due to conditions such as arthritis or trauma, and aims to improve the patient's range of motion and quality of life.

1. Indications

Arthroplasty of the elbow with distal humeral prosthetic replacement is indicated for several specific conditions that lead to significant impairment of elbow function. These include:

  • Severe Osteoarthritis - A degenerative joint disease characterized by the breakdown of cartilage, leading to pain and reduced mobility.
  • Rheumatoid Arthritis - An autoimmune condition that causes chronic inflammation of the joints, resulting in pain, swelling, and eventual joint damage.
  • Post-Traumatic Arthritis - Arthritis that develops following an injury to the elbow, such as fractures or dislocations, which can lead to joint degeneration.
  • Elbow Fractures - Complex fractures of the distal humerus that may not heal properly or result in malunion, necessitating surgical intervention.
  • Failed Previous Elbow Surgery - Cases where prior surgical attempts to repair or reconstruct the elbow have not resulted in satisfactory outcomes.

2. Procedure

The procedure for elbow arthroplasty with distal humeral prosthetic replacement involves several critical steps to ensure successful implantation and recovery. The process begins with:

  • Step 1: Incision and Exposure - A skin incision is made over the elbow joint, either medial or lateral to the olecranon process. This incision allows access to the underlying structures of the elbow joint.
  • Step 2: Soft Tissue Dissection - The surgeon carefully dissects the soft tissues to expose the ulnar nerve, which is identified and protected throughout the procedure to prevent injury.
  • Step 3: Joint Access - The lateral epicondyle of the humerus is exposed, and the interval between the anconeus and flexor carpi ulnaris is incised. The triceps muscle is mobilized to facilitate access to the joint.
  • Step 4: Elbow Joint Preparation - The anconeus is elevated off the lateral aspect of the proximal ulna, and the radial aspect of the elbow joint is addressed by dissecting tissue off the lateral epicondyle. The elbow is then externally rotated and flexed to allow for better visualization and access.
  • Step 5: Capsule and Ligament Management - The posterior joint capsule is removed, and the roof of the olecranon is exposed. The medial collateral ligament is released from the epicondyle to facilitate the procedure.
  • Step 6: Humeral Preparation - Tissue is dissected off the humerus, and the roof of the olecranon fossa is removed down to the level of cancellous bone. The humeral canal is then reamed to prepare for the prosthetic implant.
  • Step 7: Implant Placement - A cutting guide is placed, and the distal aspect of the humerus is removed along the plane of the medial and lateral supracondylar columns. A trial implant is placed to check for proper width and alignment before the final implant is secured.
  • Step 8: Finalizing the Implant - The articular surfaces of the ulna and radius are smoothed, and the permanent humeral implant is placed. Bone cement is injected in a retrograde fashion to secure the implant in place.
  • Step 9: Reattachment of Soft Tissues - Ligaments and tendons are reattached, and if necessary, a fascia lata graft may be harvested for elbow ligament reconstruction before reattachment.
  • Step 10: Closure - The triceps muscle is medialized, and a subcutaneous pocket is created for the ulnar nerve, which is placed between subcutaneous fat and fascia near the medial epicondyle. The fascia and skin are then closed in layers.
  • Step 11: Postoperative Stabilization - The arm is fully extended and placed in a splint to support the healing process.

3. Post-Procedure

After the arthroplasty procedure, patients can expect a recovery period that includes monitoring for any complications and managing pain. The arm will be placed in a splint to immobilize the elbow and promote healing. Physical therapy may be initiated to restore range of motion and strength as healing progresses. Patients are advised to follow up with their healthcare provider to assess the healing process and ensure proper rehabilitation. It is essential to adhere to postoperative care instructions to optimize recovery and achieve the best functional outcomes.

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.
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
62 Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
82 Assistant surgeon (when qualified resident surgeon not available): the unavailability of a qualified resident surgeon is a prerequisite for use of modifier 82 appended to the usual procedure code number(s).
