Accessory Digit Removal: Mr Nakul Patel Plastic Surgeon

Overview

A careful, gentle approach

An accessory digit — or extra finger or toe — is one of the most common congenital hand and foot differences, occurring in approximately 1 in every 1,000 births. The medical term for extra digits is polydactyly. In many cases the extra digit is a small, soft tag-like structure attached to the little finger or little toe side of the hand or foot. In others it is a more fully formed digit with its own bones, joints, tendons, and nerves. The condition can occur on one or both sides and can affect the hands, feet, or both. Surgical removal of an accessory digit is a straightforward, well-established procedure when performed by an experienced plastic or hand surgeon. The aim is to leave the child with a completely normal-looking and fully functioning hand or foot, with a well-healed scar that will be inconspicuous as the child grows. Mr Nakul Patel offers expert accessory digit removal for infants and children in Leicester, Nottingham, and across the East Midlands, with a careful, gentle approach tailored to the child's age, anatomy, and the type of polydactyly present.

The Condition

Types of Accessory Digit

Postaxial polydactyly — on the little-finger side — is by far the most common type.

Preaxial polydactyly is duplication on the thumb (radial) side of the hand, typically presenting as a bifurcated or doubled thumb. This is a more complex condition, as the two components are often connected at the skeleton and share tendons, with one component selected to retain and reconstruct for the best result — thumb duplication surgery requires careful planning and specialist hand surgery expertise. Postaxial polydactyly — duplication on the little finger side — is by far the most common type, ranging from a simple soft tissue tag containing no bone (Type B, the most common and easiest to address) to a fully formed extra digit with its own metacarpal, bones, and joints (Type A, which requires more formal surgical excision with bone and joint work). Central polydactyly affects the index, middle, or ring fingers, is less common, and is often associated with syndactyly (fusion of adjacent fingers), requiring careful reconstructive planning. Toe polydactyly most commonly affects the little toe side; the extra digit may be a soft tissue tag or a more formed structure, and surgical removal follows similar principles to hand polydactyly, usually performed during the same anaesthetic window if both hands and feet are affected.

Benefits

The Aims of Surgery

The goal is a completely normal-looking and fully functioning hand or foot, achieved safely and with the least possible scarring.

Normal Appearance

A completely normal-looking hand or foot, with no visible remnant of the accessory digit.

Full Function

A fully functioning hand or foot, achieved through careful surgical technique tailored to the type of polydactyly present.

Inconspicuous Scar

A well-healed scar that will be inconspicuous as the child grows.

Complete Removal

Formal surgical excision avoids the incomplete removal that can occur when a tag digit is simply tied off (ligated) at birth.

Avoids Neuroma

The nerve running through the stalk is divided under direct vision rather than blindly ligated, avoiding painful neuroma formation.

Mr Patel will explain how these aims apply to your child's specific type of accessory digit at consultation.

Suitability

When Is Your Child Ready for Surgery?

Timing balances anaesthetic safety, hand or foot development, and your family's circumstances.

Is thriving and well, and around 6 to 12 months of age or older — most centres are comfortable with elective general anaesthetic from this point
Has hand polydactyly and is between 6 months and 2 years old — ideally before strong hand patterns develop around the extra digit
Has toe polydactyly causing footwear fitting difficulties, which may bring timing forward

Your child is not yet thriving or well enough for elective general anaesthetic — timing will be adjusted accordingly

Techniques

The Procedure

The most appropriate technique depends on the type of accessory digit present. Mr Patel will discuss the most appropriate approach for your child at consultation.

Technique	Best For	Key Features	Scar	Outcome
Simple Tag Excision	Soft tissue tag, no bone (Type B)	Stalk excised at base; nerve divided under direct vision	Flat, inconspicuous	No visible remnant
Bony Digit Excision	Digit with its own bone (Type A)	Bone excision; soft tissue reconstruction	Smooth border	Normal contour
Thumb Duplication Reconstruction	Preaxial (thumb) duplication	X-ray planning; ligament and tendon reconstruction	Site-specific	Single functional thumb

Risks & Complications

Accessory digit removal is a well-established procedure. As with any surgery, potential risks include the following, which will be discussed at consultation.

Mild swelling, bruising, and tenderness — expected and resolve quickly
A small scar along the side of the digit — minimised by careful technique

Wound breakdown or infection
Neuroma formation — a painful nerve lump if the nerve was not divided cleanly under direct vision; avoided by proper surgical technique
Bony remnant — if the underlying bone was not completely removed at the metacarpal base; may require secondary correction
Skin redundancy or "dog ear" at the closure site — occasionally requires minor revision
Asymmetry or contour irregularity
Need for further surgery — particularly for complex polydactyly types

Anaesthetic complications — managed by a specialist paediatric anaesthetic team
For thumb duplication: stiffness, instability, or shortening of the reconstructed thumb — discussed in detail at consultation

Questions

Frequently Asked

A small, narrow-based accessory digit (often called a skin tag) on the little-finger or little-toe side is usually an isolated finding and not a cause for concern. Mr Patel will examine your baby to confirm there's no bony or joint connection to the adjacent normal digit before recommending removal.

Accessory digits are one of the most common congenital hand and foot differences, particularly on the little-finger side, and are frequently seen in babies with no other abnormalities.

Formal surgical excision is typically planned for around 6 to 12 months of age, once your baby is fit for a short general anaesthetic, rather than performed at birth.

Mr Patel generally uses dissolvable sutures, so a separate stitch-removal appointment usually isn't needed — the wound is checked at a follow-up visit to confirm healing is on track.

Yes. For a simple accessory digit with no bony connection to the adjacent finger or toe, function is expected to be entirely normal after removal and healing.

Yes. Thumb duplication is more structurally complex than a little-finger-side accessory digit — it often involves shared bone, joint, or tendon structures — so it requires more detailed reconstructive planning and is assessed individually rather than treated as a simple tag excision.

Mr Patel's aim is complete excision of the accessory digit, including any bony or cartilaginous component at its base, to avoid leaving behind a residual nubbin or bump.

Yes — this is a very short, minor procedure, and modern paediatric anaesthesia is well established as safe for babies from around 6 months of age. Your anaesthetist will discuss your baby's individual fitness for anaesthesia at the pre-operative assessment.

In some centres, tag digits are tied off (ligated) at birth. However, this approach carries risks of incomplete removal, neuroma formation — a painful lump from a divided nerve — and unsatisfactory cosmesis. Mr Patel recommends formal surgical excision under general anaesthetic for a safer, more complete, and cosmetically superior result.
