Official Description

Talectomy (astragalectomy)

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

A talectomy, also known as an astragalectomy, is a surgical procedure that involves the removal of the talus, which is one of the seven tarsal bones in the human foot. The talus is a critical bone located at the top of the foot, forming a joint with the tibia and fibula, the two long bones of the lower leg. This procedure is typically indicated in cases where the talus is damaged or diseased, necessitating its removal to alleviate pain or restore function. The surgery is performed through an anterolateral approach, which allows the surgeon to access the talus effectively while minimizing damage to surrounding structures. During the procedure, the extensor tendons and nearby blood vessels are carefully mobilized to provide a clear view of the talus. All ligamentous and capsular attachments are meticulously released to facilitate the removal of the talus. After the talus is excised, the calcaneus, or heel bone, is repositioned posteriorly, and the surgical site is thoroughly inspected to ensure that no remnants of the talus remain. The calcaneus is then aligned with the distal tibia, and the foot is placed in a balanced plantigrade position, which is essential for proper healing and function. To maintain this alignment, a pin is inserted across the calcaneus and into the tibia, and a cast is applied to immobilize the foot and ankle during the recovery process.

1. Indications

The talectomy procedure is indicated for various conditions affecting the talus that may lead to significant pain or dysfunction. The following are explicitly provided indications for performing a talectomy:

  • Severe Osteoarthritis - When the talus is severely affected by osteoarthritis, leading to joint pain and reduced mobility.
  • Traumatic Injury - In cases of significant trauma to the talus, such as fractures that cannot be repaired or have resulted in avascular necrosis.
  • Bone Tumors - The presence of benign or malignant tumors in the talus that necessitate removal for treatment or to prevent further complications.
  • Chronic Pain - Persistent pain in the ankle region that is unresponsive to conservative treatments and is attributed to talar pathology.

2. Procedure

The talectomy procedure involves several critical steps to ensure the successful removal of the talus while preserving surrounding structures. The following procedural steps are outlined:

  • Step 1: Anterolateral Approach - The surgeon begins by making an incision over the lateral, intermediate, and medial malleoli to access the talus. This approach allows for optimal visualization and access to the bone.
  • Step 2: Mobilization of Tendons and Vessels - Once the incision is made, the extensor tendons and surrounding blood vessels are carefully mobilized to prevent damage during the procedure. This step is crucial for maintaining blood supply and function of the foot.
  • Step 3: Release of Ligamentous Attachments - The surgeon meticulously releases all ligamentous and capsular attachments of the talus. This step is essential to ensure that the talus can be removed without leaving any remnants behind.
  • Step 4: Removal of the Talus - The talus is then excised from its position. The surgeon ensures that the surgical site is thoroughly inspected to confirm that no talar remnants remain, which is vital for preventing complications.
  • Step 5: Repositioning of the Calcaneus - After the talus is removed, the calcaneus is displaced posteriorly and aligned with the distal tibia. This alignment is critical for restoring the foot's anatomical position.
  • Step 6: Stabilization and Immobilization - To maintain the alignment of the calcaneus with the tibia, a pin is placed across the calcaneus and into the tibia. Finally, a cast is applied to immobilize the foot and ankle, facilitating proper healing.

3. Post-Procedure

Post-procedure care following a talectomy is essential for optimal recovery. After the surgery, the patient will typically be monitored for any immediate complications. The cast applied during the procedure will help immobilize the foot and ankle, allowing for proper healing of the surgical site. Patients are usually advised to keep the foot elevated to reduce swelling and to follow specific weight-bearing restrictions as directed by the surgeon. Follow-up appointments will be necessary to assess healing and to determine when physical therapy may begin to restore function and strength to the foot. Pain management strategies will also be discussed to ensure patient comfort during the recovery process.

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.
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).
