Overview

• Fingertip injuries in children are common and result in significant burden [1].
• Most fingertip injuries in children are preventable [1].
• Most fingertip injuries in children occur at home, often involving a door or window [1].
• Injuries to the fingertip must be treated with the same care as other hand surgery [2].
• Treatment of fingertip injuries should provide coverage to the tip of the finger with good quality skin [2].
• Treatment of fingertip injuries should aim for the best sensibility possible [2].
• The incidence of infection after distal fingertip amputation and crush injury is 2.5% [3].
• There is no meaningful difference in infection rates between groups with and without prophylactic antibiotics after distal fingertip injuries [3].
• The low incidence of infection and lack of difference between groups call into question prophylactic antibiotic prescribing after distal fingertip injuries [3].

Anatomy & Pathophysiology

• Minimal requirements for hand function include a stable wrist and two opposing sensate digits [15].
• Preservation of thumb-finger pinch takes priority in functional hand requirements [15].
• Preservation of digito-palmar grip takes priority in functional hand requirements [15].
• The hand requires at least two sensate digits that can oppose with some power for functional prehension [26].
• Sensation constitutes 40% of the goal in thumb or fingertip repair [23].
• Length and appearance account for 50% of the goal in thumb or fingertip repair [23].
• A normal hand is not achievable through reconstruction, but improved function in sensibility, movement, communication, emotion, psychological, or aesthetic factors is achievable [28].
• Digit replantation does not restore premorbid hand function but results in adequate hand function [47].
• Basic function can almost always be restored in most severe upper limb injuries using current reconstructive techniques [51].
• Microsurgical toe-to-hand transplantation provides thumb and finger reconstruction superior to conventional techniques in appearance and function for the mutilated hand [48].
• The primary disadvantage of pollicization of the second metacarpal is narrowing of the palm width, which may result in reduced grip strength in manual laborers [46].
• Early placement of the hand in the position of function minimizes late complications such as restricted motion [35].
• The importance of a flexor-tendon graft in the severely injured hand is judged by its contribution to overall function rather than the exact degree of motion obtained [53].
