Official Description

Closed treatment of ankle dislocation; requiring anesthesia, with or without percutaneous skeletal fixation

© Copyright 2025 American Medical Association. All rights reserved.

Common Language Description

Closed treatment of an ankle dislocation involves the non-surgical realignment of the ankle joint that has been displaced due to injury. This procedure is typically performed under anesthesia to ensure patient comfort and minimize pain during the manipulation of the joint. Ankle dislocations, particularly those without accompanying fractures, are uncommon but can lead to serious complications, such as neurovascular impairment, if not promptly addressed. The evaluation of the neurovascular status of the foot is a critical step in the process; signs of compromise, such as coldness, discoloration, or absence of pulse or sensation, necessitate immediate reduction of the dislocation, often without the need for pre-reduction imaging. In cases where the neurovascular status is stable, radiographs may be obtained to assess the injury before proceeding with treatment. The most frequently encountered type of ankle dislocation is a posterior dislocation of the talus, which requires specific techniques for reduction. The procedure involves careful manipulation of the foot and ankle, applying traction in various directions depending on the type of dislocation. After successful reduction, the neurovascular status is re-evaluated, and a long leg sugar tong posterior splint is applied to immobilize the joint, maintaining it in a position of 90-degree flexion. This immobilization is crucial for the healing of soft tissue structures surrounding the joint. In some cases, percutaneous skeletal fixation may be utilized to stabilize the joint further, particularly when there is a need for additional support during the healing process.

1. Indications

Closed treatment of ankle dislocation is indicated for the following conditions:

  • Ankle Dislocation The primary indication for this procedure is the presence of an ankle dislocation, which may occur due to trauma or injury.
  • Neurovascular Compromise If there are signs of neurovascular impairment, such as coldness, discoloration, or lack of pulse or sensation in the foot, immediate treatment is required to prevent further complications.
  • Stable Neurovascular Status When the neurovascular status is stable, the procedure may be performed to restore proper alignment of the ankle joint.

2. Procedure

The closed treatment of an ankle dislocation involves several key procedural steps:

  • Evaluation of Neurovascular Status The first step is to assess the neurovascular status of the foot. This evaluation is crucial to determine if there is any compromise that requires immediate intervention.
  • Reduction Technique for Posterior Dislocation For a posterior dislocation of the talus, the foot is held in plantar flexion. An assistant applies axial traction by grasping the distal foot and exerting a constant force. The tibia is then grasped above the dislocation, and posterior traction is applied with one hand while the other hand applies anterior pressure on the heel. This coordinated effort typically results in reduction within moments.
  • Reduction Technique for Anterior Dislocation In cases of anterior dislocation, the procedure involves applying anterior traction with one hand while simultaneously applying axial traction and posterior force with the other hand to facilitate reduction.
  • Reduction Technique for Lateral Dislocation For lateral dislocations, lateral traction is applied with one hand, while the other hand exerts medial pressure to achieve proper alignment.
  • Reduction Technique for Medial Dislocation In the case of medial dislocations, medial traction is applied with one hand, and lateral pressure is applied with the other hand to restore the joint's normal position.
  • Post-Reduction Evaluation After reduction, the neurovascular status is re-evaluated to ensure that normal blood flow and sensation have been restored.
  • Immobilization A long leg sugar tong posterior splint is then applied to immobilize the ankle joint, maintaining it in a 90-degree flexion position to support healing.
  • Follow-Up Radiographs A second set of radiographs may be obtained to confirm the anatomic alignment of the ankle structures after the reduction and immobilization.
  • Optional Skeletal Fixation If necessary, percutaneous skeletal fixation may be performed using radiologic guidance, where pins are placed through the skin and across the ankle joint to provide additional stabilization during the healing process.

3. Post-Procedure

Following the closed treatment of an ankle dislocation, it is essential to monitor the patient for any signs of complications. The neurovascular status should be continuously evaluated to ensure that there are no issues with blood flow or sensation. The long leg sugar tong posterior splint will help immobilize the joint, allowing for proper healing of the soft tissue structures. Patients may be advised on weight-bearing restrictions and the importance of follow-up appointments to assess healing and alignment. Additional imaging may be required to confirm the success of the reduction and to monitor the healing process. If percutaneous fixation was utilized, the stability of the pins should also be assessed during follow-up visits.

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).
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).
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.)
