Toe amputation is a surgical procedure often necessitated by severe infections, trauma, or underlying medical conditions such as diabetes and peripheral artery disease. This article provides a comprehensive overview of toe amputation, including indications, surgical techniques, postoperative care, and potential complications [1].

Toe amputation is a common surgical procedure performed to remove one or more toes due to various medical conditions [2]. The goal of this procedure is to alleviate pain, prevent infection from spreading, and improve the patient's overall quality of life. The necessity for toe amputation can arise due to infections, vascular diseases, trauma, tumors, or congenital deformities. Toe amputation is a surgical procedure involving the removal of one or more toes, typically performed to treat severe trauma, infection, necrosis, or chronic conditions such as diabetes and peripheral arterial disease (PAD) [3]. Although the procedure may seem minor compared to larger limb amputations, it carries significant implications for a patient’s mobility, quality of life, and overall health. Understanding the indications, surgical techniques, potential complications, and postoperative care is essential for both healthcare providers and patients to ensure optimal outcomes. The decision to amputate a toe is often driven by the need to prevent the spread of infection or necrosis, alleviate chronic pain, or address structural deformities. Diabetic foot ulcers, a common complication of poorly controlled diabetes, are one of the primary causes leading to toe amputation [4]. In cases of gangrene or severe infection, amputation may become necessary to prevent systemic spread and preserve the patient’s overall health [5]. Additionally, traumatic injuries, such as crush injuries or frostbite, may warrant toe amputation when tissue viability is compromised. Other indications include congenital abnormalities, malignant tumors, or chronic deformities causing pain and functional impairment. The surgical procedure itself varies based on the affected toe, the severity of the condition, and the underlying pathology. Surgeons aim to preserve as much healthy tissue as possible while ensuring complete removal of the damaged or diseased area [6]. Techniques may range from simple disarticulation of the phalangeal joints to partial or full toe removal, sometimes including adjacent tissue if infection or necrosis has spread. Proper surgical planning and execution are crucial to minimize complications and enhance the likelihood of a functional recovery. Complications following toe amputation can range from minor wound infections to more severe issues, such as poor healing, chronic pain, or further tissue necrosis, particularly in patients with vascular conditions or diabetes [7]. Postoperative care is a critical aspect of the recovery process. It involves wound management, pain control, physical therapy, and the use of appropriate footwear or orthotic devices. The goal of postoperative care is to promote healing, prevent complications, and help the patient regain maximum functionality and mobility. In some cases, psychological support and rehabilitation may be necessary, as the loss of even a single toe can affect balance, gait, and emotional well-being [8].

Understanding the comprehensive aspects of toe amputation—from its indications and surgical techniques to its complications and recovery process—enables healthcare providers to make informed decisions and offer better patient care. It also empowers patients to actively participate in their recovery, adhere to preventive measures, and improve their overall quality of life.

Indications for toe amputation

Several conditions may necessitate a toe amputation, including:

Diabetes and Peripheral Neuropathy: Uncontrolled diabetes often leads to peripheral neuropathy, which results in foot ulcers and infections.

Peripheral Artery Disease (PAD): Poor circulation can lead to tissue necrosis, necessitating amputation.

Severe Infections: Osteomyelitis (bone infection) or gangrene may require surgical intervention.

Trauma and Injury: Crush injuries or severe fractures may necessitate amputation.

Tumors or Malignancies: Some cancers affecting the toes require removal to prevent metastasis.

Congenital Deformities: Severe deformities affecting functionality may require amputation.

Types of toe amputations

Toe amputations are classified based on the level of amputation:

Partial toe amputation, removal of only a part of the affected toe.

Complete toe amputation, removal of the entire toe at the metatarsophalangeal joint.

Ray amputation, removal of the toe along with part of the metatarsal bone.

Tran’s metatarsal amputation, amputation of multiple toes, involving the forefoot.

The procedure generally follows these steps:

Assessment of circulation via Doppler ultrasound or angiography.

Infection control with antibiotics.

Blood sugar control in diabetic patients.

Local, regional, or general anesthesia is administered based on the patient’s condition.

Surgical techniques

An incision is made to remove the affected tissue while preserving as much viable tissue as possible [6].

Careful debridement and bone trimming are performed.

The wound is either closed primarily or left open to heal secondarily in cases of infection.

• Wound care with dressing changes.
• Pain management with analgesics.
• Antibiotics if infection is present.
• Physical therapy to restore mobility and balance.

Potential complications

Although toe amputation is generally safe, potential complications include:

• Infection: Especially in patients with diabetes or poor circulation.
• Delayed Healing: Common in patients with vascular diseases [7].
• Phantom Pain: Some patients experience sensations from the missing toe.
• Gait Imbalance: Loss of toes can affect walking and require orthotic support.
• Recurrence of Infection: Incomplete removal of infected tissue can lead to reinfection.

Recovery and rehabilitation

Recovery time depends on the extent of amputation and the patient’s overall health:

Typically 4-6 weeks for soft tissue healing.

Physical therapy for gait training [8].

Custom footwear or orthotics for balance support.

Regular follow-up to monitor wound healing.

Proper foot care to prevent complications.

Blood sugar control for diabetic patients.

Smoking cessation to improve circulation.

Conclusion

Toe amputation is a necessary surgical intervention in cases of severe infections, trauma, and vascular diseases. With proper surgical techniques and postoperative care, patients can achieve satisfactory functional outcomes. Early detection and management of risk factors can help in preventing the need for amputation.
