This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

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].
• Secondary procedures are often necessary following hand and digit replants [6].
• Demographics play a significant role in the decision for finger replantation and its outcomes, in addition to injury factors [7].
• Age alone should not be an absolute contraindication to finger replantation [21].
• Patient preference is not driving the decrease in finger replantations in the US [32].
• Surgical indications for distal replantation, nail bed, and nail problems in musicians are often difficult because technical demands may not be familiar to the hand surgeon [11].
• The expectation of returning to 'normal' is not always possible in severe trauma for musicians with distal replantation, nail bed, or nail problems [11].
• There is insufficient evidence to determine the best treatment method for composite defects of the fingertips due to the lack of prospective randomized trials and disparate retrospective case series [13].
• The philosophy of digital replantation aims to ensure not only the survival of a digit but its functional use as well [22].
• The current data are inadequate to make comments regarding donor site morbidity for toe-to-thumb transfers for isolated traumatic thumb amputation [23].
• An evidence-based recommendation for the superiority of a specific type of toe-to-thumb transfer cannot be made [23].
• The low incidence of infection (2.5%) and lack of a meaningful difference between groups call into question prophylactic antibiotic prescribing after distal fingertip amputation and crush injuries [4].

Anatomy & Pathophysiology

• Demographics play a significant role in the decision for finger replantation and its outcomes [7].
• Sex, age, and regional differences are observed in partial hand and finger amputations, suggesting disparities in burden [42].
• Understanding differences in anatomy, physiology, mechanism of injury, surgical technique, and outcomes is crucial for pediatric replantation results [39].

• Secondary procedures are often necessary following hand and digit replants [6].
• Demographics play a significant role in the decision for finger replantation and its outcomes in pediatric patients, in addition to injury factors [7].
• The treatment of the mutilated hand is considered the most challenging acute hand injury that hand surgeons treat [10].
• Surgical indications for distal replantation, nail bed, and nail problems in musicians are often difficult due to technical demands unfamiliar to hand surgeons and unrealistic patient expectations of returning to 'normal' after severe trauma [11].
• Age significantly influences the survival rate of digital replantation [16].
• The injured hand significantly influences the survival rate of digital replantation [16].
• Injury type significantly influences the survival rate of digital replantation [16].

• The amputations of the distal phalanx and the thumb seem to have a somewhat worse prognosis for digit replantation [14].
• Male sex seems to have a somewhat worse prognosis for digit replantation [14].
• Ischemia time of greater than 12 hours seems to have a somewhat worse prognosis for digit replantation [14].
• Demographics play a significant role in the decision for finger replantation and its outcomes in pediatric patients [7].
• Digital amputation is common in the setting of diabetic finger infection [31].
• Hand surgeons should consider prognostic implications when counseling patients regarding mortality and revision following digital amputation for infection and necrosis [18].

Investigations

• Fingertip injuries in children are common and result in a significant burden [1].
• Most fingertip injuries in children occur at home, specifically involving doors or windows [1].
• Fingertip injuries in the context of abuse may indicate abuse or neglect [9].
• Complications of distal phalanx fractures in children are frequent [44].

Treatment

General Management Principles

• Proper management of fingertip injuries focuses on robust soft-tissue coverage, maximizing functional length, and preserving nail function to achieve good outcomes [5].
• The precise management of fingertip injuries in adults depends on the degree of injury, with various operative and non-operative techniques available for successful employment [8].
• Conservative treatment with semiocclusive dressings is increasingly acceptable for fingertip and thumb tip injuries due to excellent results in restoring contour, sensibility, and aesthetics [34].

Antibiotic Prophylaxis

• Prophylactic antibiotic prescribing after distal fingertip amputation and crush injury is questionable due to a low infection incidence (2.5%) and lack of meaningful difference between groups [4].

Operative Reconstruction Techniques

• The parallelogram flap is considered a better choice than the homodigital island flap for reconstruction of fingertip defects with bone exposure [2].
• Application of artificial dermis combined with a medial flap from the second toe restores fingernail appearance and preserves finger length and function without damaging the toenail in degloving injuries [3].
• Specific techniques can be incorporated to improve efficiency and success in digit replantation [24].

Digital Replantation and Revascularization

• The decision to replant, revascularize, or amputate a nonviable digit is related to injury factors (mechanism, affected digit, zone of injury) and the surgeon [38].
• Factors significantly influencing the survival rate of digital replantation include age, injured hand, injury type, zone, and the method of preservation of the amputated digit [16].
• The need for a vein graft for a large zone of injury should not be considered a relative contraindication to perform revascularization or replantation of dysvascular digits [30].
• Both functional outcomes and patient-reported outcomes facilitate a comprehensive assessment of the benefits of replantation for amputation injuries in the hand [15].
• Treatment of the mutilated hand is considered one of the most challenging acute hand injuries for hand surgeons [10].

Toe-to-Thumb Transfers

• Current data are inadequate to make comments regarding donor site morbidity for toe-to-thumb transfers [23].

Complications

• Secondary procedures are often necessary following hand and digit replantation [6].
• Infections can mimic common conditions in the fingertip, requiring awareness of obscure conditions and relevant anatomy [12].
• Amputations of the distal phalanx have a somewhat worse prognosis [14].
• Amputations of the thumb have a somewhat worse prognosis [14].
• Male gender is associated with a somewhat worse prognosis for digit replantation [14].
• Ischemia time greater than 12 hours is associated with a somewhat worse prognosis for digit replantation [14].
• Traumatic finger amputations have a bimodal incidence [20].
• The epidemiology and mechanism of injury for traumatic finger amputations change with age [20].
• Delaying replantation of digits overnight yields survival outcomes comparable to immediate replantation in selected cases [26].
• There is no significant difference in the incidence of unplanned or secondary revision of fingertip amputation after initial procedure performed in the ED versus the OR [35].

Recovery

• Incorporating specific techniques improves efficiency and success in digit replantation [24].
• For simple nailbed injuries, patients have consistently good early outcomes irrespective of the intervention [25].
• Most patients with fingertip injuries can achieve good outcomes with proper management focusing on robust soft-tissue coverage, maximizing functional length, and preserving nail function [5].
