Acetabuloplasty; resection, femoral head (eg, Girdlestone procedure)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

An acetabuloplasty with resection of the femoral head, commonly known as the Girdlestone procedure, is a surgical intervention aimed at addressing severe hip joint issues. This procedure entails the removal of both cartilage and bone from the acetabulum, which is the socket of the hip joint, as well as the resection of the femoral head, the upper part of the thigh bone that fits into the acetabulum. The primary goal of this surgery is to facilitate the fusion of the acetabulum and femur, thereby alleviating pain and restoring function in patients who have experienced complications from previous hip surgeries or have conditions such as primary septic arthritis or secondary infections following hip replacement. The procedure is typically indicated for patients suffering from painful, failed total hip arthroplasties, where conservative treatments have proven ineffective. The surgical approach involves making an incision on the lateral side of the hip, followed by careful dissection of the surrounding soft tissues to gain access to the hip joint. Once the joint is accessed, the femoral head is dislocated from the acetabulum, and the joint is thoroughly cleaned with sterile saline to prepare for the resection. The use of an osteotome allows for the precise removal of the damaged cartilage and bone from the acetabulum, and the excision of the femoral head and/or neck is performed to ensure proper alignment and positioning of the remaining femur within the acetabulum. To stabilize the hip joint post-surgery and prevent movement during the healing process, a hip spica cast is applied, which plays a crucial role in the recovery phase.

1. Indications

The Girdlestone procedure is indicated for specific conditions and situations where traditional hip joint treatments have failed or are not viable. The following are the explicitly provided indications for performing this procedure:

  • Painful, failed total hip procedures - This includes patients who have undergone total hip arthroplasty but continue to experience significant pain and dysfunction.
  • Primary septic arthritis - This condition involves an infection in the hip joint that can lead to severe inflammation and damage, necessitating surgical intervention.
  • Secondary infection of the hip following hip replacement surgery - Patients who develop infections after a hip replacement may require this procedure to address the complications arising from the infection.

2. Procedure

The Girdlestone procedure involves several critical steps to ensure effective resection and stabilization of the hip joint. The following procedural steps are outlined:

  • Step 1: Incision and Exposure - The procedure begins with the surgeon making an incision over the lateral aspect of the hip. This incision allows for adequate access to the hip joint. Following the incision, soft tissues surrounding the hip are carefully dissected and released to expose the hip joint fully.
  • Step 2: Dislocation of the Femoral Head - Once the hip joint is exposed, the femoral head is dislocated from the acetabulum. This step is crucial as it provides the necessary access to the acetabulum for the subsequent resection.
  • Step 3: Joint Flushing - After dislocation, the joint is flushed with sterile saline. This step helps to clean the joint space and remove any debris or infected material, preparing the area for the resection.
  • Step 4: Resection of Cartilage and Bone - Using an osteotome, the surgeon removes the damaged cartilage and bone from the surface of the acetabulum. This step is essential for creating a suitable surface for the femur to fuse with the acetabulum.
  • Step 5: Excision of the Femoral Head and/or Neck - The procedure may involve the excision of part or all of the femoral head and/or neck. This excision is performed to ensure that the remaining portion of the femur can be properly positioned within the acetabulum.
  • Step 6: Positioning of the Femur - After the resection, the remaining portion of the femur is positioned in the acetabulum. This alignment is critical for the success of the procedure and the eventual fusion of the bones.
  • Step 7: Application of Hip Spica Cast - Finally, a hip spica cast is applied to the patient. This cast is designed to immobilize the hip joint, preventing movement and allowing for proper healing and stabilization of the joint.

3. Post-Procedure

Post-procedure care following the Girdlestone procedure is essential for optimal recovery. Patients can expect a period of immobilization due to the application of the hip spica cast, which is crucial for preventing movement of the hip joint during the healing process. The duration of immobilization may vary based on individual recovery and the surgeon's recommendations. Patients will typically require follow-up appointments to monitor healing and assess the success of the procedure. Pain management strategies will be implemented to address any discomfort during the recovery phase. Physical therapy may be introduced gradually to help restore mobility and strength once the initial healing has occurred. It is important for patients to adhere to their post-operative care instructions and attend all follow-up visits to ensure proper recovery and to address any potential complications that may arise.

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).
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).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) 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).
