Official Description

Arthrotomy, wrist joint; with synovectomy

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Arthrotomy of the wrist joint with synovectomy is a surgical procedure aimed at addressing inflammation of the synovial tissue, which is often a result of conditions such as rheumatoid arthritis. The synovial tissue lines the joints and produces synovial fluid, which lubricates the joint. In cases of inflammation, this tissue can become thickened and painful, leading to decreased joint function. The procedure involves making an incision over the wrist to access the joint space, allowing for the removal of the inflamed synovial tissue. This intervention is typically performed under general or regional anesthesia, with the patient positioned supine and the arm secured to facilitate access to the wrist. The use of a pneumatic tourniquet helps to minimize blood loss during the surgery. The surgical approach may vary based on the specific location of the pathology, and careful dissection is necessary to protect surrounding nerves and blood vessels. The ultimate goal of the synovectomy is to relieve pain, improve joint function, and enhance the overall quality of life for patients suffering from chronic inflammatory conditions affecting the wrist joint.

1. Indications

Arthrotomy of the wrist joint with synovectomy is indicated for the following conditions:

  • Rheumatoid Arthritis - A chronic inflammatory disorder that affects the synovial tissue, leading to pain and swelling in the wrist joint.
  • Synovitis - Inflammation of the synovial membrane, which can cause joint pain and stiffness.
  • Other Inflammatory Joint Diseases - Conditions that result in synovial inflammation and may benefit from the removal of inflamed tissue.

2. Procedure

The procedure for arthrotomy of the wrist joint with synovectomy involves several key steps:

  • Step 1: Patient Positioning - The patient is placed in a supine position with the shoulder abducted to allow optimal access to the wrist joint. This positioning is crucial for the surgeon to perform the procedure effectively.
  • Step 2: Application of Pneumatic Tourniquet - A pneumatic tourniquet is applied to the upper arm to minimize blood flow to the surgical site, thereby reducing blood loss during the operation.
  • Step 3: Incision - A longitudinal midline incision or a horizontal incision along Langer's lines is made over the dorsal aspect of the wrist, depending on the specific site of the pathology. This incision allows access to the underlying structures.
  • Step 4: Development of Skin Flaps - Full thickness skin flaps are developed down to the extensor retinaculum, with careful attention to protect the superficial radial nerve, the dorsal sensory branch of the ulnar nerve, and associated blood vessels to prevent injury during dissection.
  • Step 5: Incision of the Retinaculum - The extensor retinaculum is incised longitudinally over the third dorsal compartment to facilitate access to the wrist joint.
  • Step 6: Exposure of Ulnar Aspect (if required) - If exposure of the ulnar aspect of the wrist is necessary, the extensor pollicis longus is retracted radially, and the fourth extensor compartment is elevated subperiosteally, or the septum between the third and fourth compartments is divided to create a flap over the ulna.
  • Step 7: Exposure of Radial Aspect (if required) - For exposure of the radial aspect of the wrist, the extensor retinaculum is elevated off Lister's tubercle, and the second dorsal compartment is released to gain access to the joint.
  • Step 8: Incision of the Wrist Capsule - The wrist capsule is incised to allow direct access to the joint space.
  • Step 9: Examination and Synovial Tissue Removal - The wrist joint is examined thoroughly, and all inflamed synovial tissue is excised to alleviate symptoms and restore function.
  • Step 10: Flushing and Closure - Upon completion of the synovectomy, the joint is flushed with normal saline to clear any debris, and the surgical wound is closed in layers to promote proper healing.

3. Post-Procedure

After the procedure, patients are typically monitored for any immediate complications. Post-operative care may include pain management, immobilization of the wrist, and instructions for gradual rehabilitation exercises to restore mobility and strength. Patients are advised to follow up with their healthcare provider to assess healing and function of the wrist joint. The expected recovery time may vary based on individual circumstances and the extent of the surgery performed.

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.
50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
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).
54 Surgical care only: when 1 physician or other qualified health care professional performs a surgical procedure and another provides preoperative and/or postoperative management, surgical services may be identified by adding modifier 54 to the usual procedure number.
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).
