Official Description

Arthrodesis, wrist; with iliac or other autograft (includes obtaining graft)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 25810 refers to an arthrodesis of the wrist, which is a surgical technique aimed at fusing the bones of the wrist joint to alleviate pain and restore function. This procedure involves the use of an autograft, which is a piece of bone taken from the patient's own body, typically from the iliac crest, to facilitate the fusion process. The surgery begins with a midline incision on the posterior aspect of the wrist, allowing access to the radiocarpal joint and the distal radioulnar joint (DRUJ). During the operation, careful attention is given to protect the superficial branch of the radial nerve, which is crucial for maintaining wrist and hand function. The surgical approach includes identifying the interval between the first and second dorsal compartments and incising the dorsal carpal ligament while preserving its attachment to the radius. This step is essential for gaining access to the underlying structures. The extensor carpi radialis longus tendon is sectioned to further expose the joint capsule, allowing for the removal of articular cartilage from the radiocarpal joint. The harvested bone autograft is then shaped appropriately and placed across the joints to promote fusion. The procedure concludes with securing the graft using a Kirschner wire, suturing the dorsal carpal ligament over the graft, and closing the surgical wound in layers, followed by immobilization of the wrist in a long arm cast. This comprehensive approach aims to achieve a stable and pain-free wrist joint through the fusion of the involved bones.

1. Indications

The procedure of wrist arthrodesis with iliac or other autograft is indicated for several specific conditions that may lead to chronic pain or instability in the wrist. These indications include:

  • Severe wrist arthritis - This condition involves the degeneration of the cartilage in the wrist joints, leading to pain and reduced mobility.
  • Wrist instability - Instability may arise from ligament injuries or previous fractures that compromise the structural integrity of the wrist.
  • Post-traumatic arthritis - This occurs following an injury to the wrist, resulting in joint damage and subsequent arthritis.
  • Failed wrist surgeries - Patients who have undergone previous surgical interventions that did not yield satisfactory results may require arthrodesis as a corrective measure.

2. Procedure

The surgical procedure for wrist arthrodesis with iliac or other autograft involves several critical steps to ensure successful fusion of the wrist bones. The process begins with:

  • Incision - A midline incision is made over the posterior aspect of the wrist, extending from the distal forearm to the proximal metacarpal area. This incision provides access to the underlying structures.
  • Exposure of joints - The radiocarpal joint and distal radioulnar joint (DRUJ) are carefully exposed. The superficial branch of the radial nerve is identified and protected to prevent nerve damage during the procedure.
  • Dorsal carpal ligament incision - The interval between the first and second dorsal compartments is located, and the dorsal carpal ligament is incised while leaving it attached to the volar aspect of the radius. This step is crucial for accessing the joint capsule.
  • Tendon retraction - Overlying tendons are retracted to provide a clear view of the joint capsule. The extensor carpi radialis longus tendon is sectioned proximal to the base of the second metacarpal to facilitate further exposure.
  • Joint capsule incision - The joint capsule is incised, allowing access to the radiocarpal, intercarpal, and second carpometacarpal joints. This step is essential for preparing the joint surfaces for grafting.
  • Articular cartilage removal - Articular cartilage is removed from the radiocarpal joint using a rongeur or bur, creating a suitable surface for the bone graft.
  • Bone autograft harvesting - A skin incision is made over the iliac crest or another site to harvest the bone autograft. The muscle is stripped to expose the bone surface, and both cortical and cancellous bone are harvested and shaped to the required size for grafting.
  • Bone graft placement - A slot is cut in the radius, carpal bones, and first and second metacarpals to accommodate the bone graft. The graft is then placed across the radiocarpal, intercarpal, and metacarpal joints.
  • Securing the graft - The bone graft is secured in place using a Kirschner wire to ensure stability during the healing process.
  • Suturing and closure - The dorsal carpal ligament is sutured over the bone graft, and the surgical wound is closed in layers to promote proper healing. Finally, the wrist is immobilized in a long arm cast to support recovery.

3. Post-Procedure

After the wrist arthrodesis procedure, patients can expect a recovery period that involves immobilization of the wrist in a long arm cast to ensure stability and promote healing of the graft. Post-operative care may include pain management, monitoring for signs of infection, and follow-up appointments to assess the healing process. Rehabilitation may be necessary to restore function and strength to the wrist once the initial healing phase is complete. Patients should be advised on activity restrictions during the recovery period to avoid complications and ensure optimal 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).
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
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.
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).
