Removal of anterior instrumentation
CPT4 code
Name of the Procedure:
Removal of Anterior Instrumentation
Common Names: Spine Hardware Removal, Anterior Spinal Instrumentation Removal
Medical Terms: Anterior Instrumentation Explantation
Summary
Removal of anterior instrumentation is a surgical procedure performed to take out hardware previously installed in the spine, such as screws, rods, or plates, which were originally placed to stabilize the spine.
Purpose
This procedure addresses medical conditions such as hardware failure, infection, pain, or spinal fusion that has healed adequately. The goals are to alleviate symptoms, resolve infections, and remove any hardware that is no longer necessary or causing complications.
Indications
- Persistent pain at the hardware site
- Infection around the instrumentation
- Hardware failure or breakage
- Successful spinal fusion where the hardware is no longer needed
- Allergic reactions or rejection of the hardware
Preparation
- Fasting for at least 8 hours before surgery
- Temporarily discontinuing certain medications such as blood thinners, per the physician's advice
- Pre-operative imaging tests like X-rays, CT scans, or MRIs to assess the hardware and spine condition
- Pre-anesthetic check-up to evaluate overall health
Procedure Description
- Anesthesia Administration: General anesthesia is administered to ensure the patient is unconscious and pain-free.
- Incision: A surgical incision is made at the previous site of hardware installation.
- Exposure: Soft tissues and muscles are carefully separated to expose the hardware.
- Removal: Screws, rods, or plates are meticulously unscrewed and removed from the spine.
- Assessment: The surgical site is examined for any signs of infection or complications.
- Closure: Muscles and tissues are repositioned, and the incision is closed with sutures or staples.
- Dressing: A sterile dressing is applied to protect the wound.
Duration
The procedure typically takes 1 to 3 hours, depending on the complexity and specific circumstances.
Setting
The procedure is performed in a hospital operating room or a specialized surgical center.

Risks and Complications
- Infection
- Bleeding
- Nerve damage
- Pain at the surgical site
- Incomplete removal of hardware
- Possible recurrence of spinal instability
Benefits
- Relief from pain or discomfort caused by the hardware
- Resolution of infection
- Improvement in overall spinal health and mobility
- Reduction of symptoms related to hardware rejection
Recovery
- Hospital stay of 1-2 days post-surgery for monitoring
- Pain management with prescribed medications
- Instructions for wound care and activity restrictions
- Follow-up appointments to monitor healing
- Gradual return to normal activities over 4-6 weeks
Alternatives
- Observation and symptom management if removal is not urgently needed
- Medication adjustments or physical therapy for pain management
- Revision surgery to replace or adjust the hardware if malfunctioning
Patient Experience
During the procedure, patients will be under general anesthesia and will not feel pain. Post-operation, patients may experience discomfort or pain, which can be managed with medications. There might be temporary restrictions on activities, and complete recovery can take several weeks. Follow-up visits are crucial to ensure proper healing and evaluate the success of the procedure.
