Fingertips serve a dual purpose:

Tactile Sensation: They provide our hands with a sense of touch, allowing us to interact with the world and perform intricate tasks.

Aesthetics: Healthy, intact nails enhance the appearance of our fingers.

The success of fingertip reimplantation depends on timing:

• The acceptable time limit for successful reimplantation is typically between 4 to 6 hours. In some cases, it can extend up to 10 to 12 hours due to the absence of significant muscle mass in the fingertip.

Consulting an experienced plastic surgeon such as Dr. Amit is crucial in fingertip injuries:

• Counseling may be necessary, particularly when children are involved.
• In some cases, flap reconstruction may yield better results than a lengthy surgery with unpredictable outcomes under anesthesia.

Upon arrival at the hospital, the following initial steps are taken:

• A thorough examination of the hand is conducted to rule out any fractures.
• Digital nerve blocks or analgesics are administered to manage pain.
• Wound cleaning and irrigation are performed.
• Blood circulation in the fingertip is assessed using capillary refill, pinprick testing, and observation of fingertip color.
• Digital X-rays are taken to identify any underlying bone injuries.
• Preoperative investigations are conducted, and the finger is immobilized.

At Kayakriti, the treatment of fingertip injuries is focused on restoring function, contour, and cosmesis in a single surgery. The approach includes:

• Cleaning the wound through irrigation.
• Debridement to remove dead tissue.
• Restoration of vascularity if blood flow is compromised.
• Fracture stabilization, typically with a K-wire or needle.
• Repair of nerves and tendons if required.
• Soft tissue coverage if the distal part is lost or damaged.

The choice of soft tissue reconstruction technique depends on various factors. Some techniques include:

• Secondary Healing: Small wounds are allowed to heal with dressings over 4-6 weeks. However, this may result in contour deformity, sensation loss, and no donor site morbidity.
• Skin Grafting: For defects limited to the skin, split or full-thickness skin grafts are used to cover well-vascularized areas. Composite grafts, such as cap grafts, can also be considered.
• Local Flaps: Various options are available to reconstruct the fingertip pulp. Common flaps used by Dr. Amit Agarwal include volar V-Y advancement flaps and lateral V-Y advancement flaps.
• Cross Finger Flap: This versatile flap utilizes skin from the adjacent finger to resurface the fingertip. It is a two-stage procedure.
  • In the first stage, the flap is harvested from the back of the finger and the raw area is covered by Skin graft.
  • In the second stage-(after 2- 3 weeks) When the flap has restored its blood supply over the defect, it is detached from the adjacent finger. Some amount of cosmetic deformity of the grafted back of the finger (area of the harvested cross-finger flap) should be acceptable to the patient.
• Thenar Flap: The thenar flap is another two-stage surgery that efficiently resurfaces fingertips with minimal morbidity to the hand.
  • In the first stage, the flap is harvested from the skin of the palm and inset over the defect and
  • In the second stage after 2-3 weeks, the flap is detached from the palm, and exercises start.

• The vascularity of the flap is closely monitored for 48 hours.
• Intravenous antibiotics are administered for one day.
• Immobilization continues until sutures mature.
• Sutures are typically removed after two weeks.
• Patients are discharged on the second day.
• Limb elevation is recommended.
• If a two-stage procedure is involved (e.g., thenar flap or cross finger flap), the second stage is performed after 2-3 weeks.
• Rehabilitation and physical therapy begin after 2 weeks, including massage over the flap after 4 weeks.
