Fingertip injuries in children treated in Department of Pediatric Surgery and Oncology in the years 2008-2010

Long-term outcomes of homodigital neurovascular island flap reconstruction of fingertip injuries in children

We evaluated the long-term functional and cosmetic results of homodigital neurovascular island flap (NIF) used to reconstruct extensive pulp defects with bone exposure in children. Twenty-three children (mean age 4.8 years, range 1-10 years) with fingertip injuries were reconstructed with a pedicled homodigital NIF and evaluated in terms of sensation quality, cold intolerance, scar formation, nail deformity, range of motion and overall finger length at a mean follow up of 7.8 years (range 2-13). Eleven patients reported cold sensitivity in the operated fingertip, and 15 presented with hook nail deformities at the final follow-up. The total active motion of the injured finger was significantly lower than that of the uninjured side (p < 0.001). NIFs is a safe, reliable reconstructive treatment for fingertip loss in children, but commonly encountered issues in the long term include an extension lag of the interphalangeal joints, hook nail deformities and cold intolerance.     Level of evidence: IV.

Long-Term Outcomes of Atasoy Flap in Children With Distal Finger Trauma

PURPOSE

Distal finger trauma is one of the most frequent emergencies in children and has the potential for functional and cosmetic damage to the hand. The Atasoy flap (AF) is a vascularized, subcutaneous pedicle V-Y advancement flap used to cover a loss of distal finger substance. Our hypothesis was that the AF is a safe, reliable flap that results in few complications and gives satisfactory functional and cosmetic results in children.

METHODS

We retrospectively assessed children with distal finger trauma and AF pulp reconstruction in our pediatric orthopedic department between 2008 and 2017. The lesion zone was classified, and we also evaluated necrosis, infection, the shape of the pulp, pulp sensitivity (Weber test), hyponychial scarring, and the presence of a hook nail deformity. Lastly, we compared patients who developed a hook nail with those who did not.

RESULTS

Thirty children were included (mean age at trauma, 6.4 years [range, 1.3-15.7 years]). In 21 cases, the finger damage was located in Ishikawa subzone II. No cases of necrosis or infection were reported. Epicritical tactile sensitivity was good in 20 patients (67%). A hook nail deformity was observed in 15 children (50%) and hyponychial scarring in 22 patients (73%). The pulp had a normal shape in 13 children (43%). The hook nail group displayed more hyponychial scarring, greater nail dystrophy, and lower pulp sensitivity.

CONCLUSIONS

The AF yielded contrasting results. High reliability, good coverage, and minimal donor-site morbidity were compromised by suboptimal tip length/shape, nail appearance, and sensitivity.

Experience of nail bed injuries at a tertiary hand trauma unit: a 12-month review and cost analysis

The aim of this study was to analyse the management of nail bed injuries from a clinical and economic perspective. We carried out a retrospective analysis of nail bed injuries treated operatively at a tertiary Plastic Surgery Hand Trauma Unit during 2016. The National Schedule of Reference Costs (2015-2016) was used to estimate the costs of treating 630 patients. The most common mechanism was a crush injury in a door (33%). Fifty-five per cent of patients had an associated tuft fracture. The minimum cost per annum for patients treated for nail bed injuries in our unit was calculated to be £511,560 (€573,362; US$666,664). Many nail bed injuries are preventable and because they present a very high financial burden on the National Health Service, targeted prevention strategies should be considered. Level of evidence: IV.

Fingertip Injuries in Children: Epidemiology, Financial Burden, and Implications for Prevention

BACKGROUND

Although fingertip injuries are common, there is limited literature on the epidemiology and hospital charges for fingertip injuries in children. This descriptive study reports the clinical features of and hospital charges for fingertip injuries in a large pediatric population treated at a tertiary medical center.

METHODS

Our hospital database was queried using International Classification of Diseases, Revision 9 (ICD-9) codes, and medical records were reviewed. Frequency statistics were generated for 1807 patients with fingertip injuries who presented to the emergency department (ED) at Boston Children's Hospital (BCH) between 2005 and 2011. Billing records were analyzed for financial data.

RESULTS

A total of 1807 patients were identified for this study; 59% were male, and the mean age at time of injury was 8 years. Most commonly, injuries occurred when a finger was crushed (n = 831, 46%) in a door or window. Average length of stay in the ED was 3 hours 45 minutes, 25% of cases needed surgery, and, on average, patients had more than 1 follow-up appointment. About one-third of patients were referred from outside institutions. The average ED charge for fingertip injuries was $1195 in 2014, which would amount to about $320 430 each year (in 2014 dollars) for fingertip injuries presenting to BCH.

CONCLUSION

Fingertip injuries in children are common and result in significant burden, yet are mostly preventable. Most injuries occur at home in a door or window. Although these patients generally heal well, fingertip injuries pose a health, time, and financial burden. Increased awareness and education may help to avoid these injuries.

Pediatric thenar flaps: a modified design, case series and review of the literature

BACKGROUND

Fingertip injuries are extremely common in children, and severe trauma with pulp loss requires soft-tissue reconstruction to restore length, bulk, and sensibility. The thenar flap is a well-described technique but there are few reports of its use in pediatric patients.

METHODS

Pediatric thenar flap reconstructions were retrospectively identified from October 2000 to October 2010 at a single institution.

RESULTS

Sixteen pediatric patients (eleven male, five female) underwent thenar flap procedures. The average age was 10.8years (1.1-17.8years). The average defect size was 1.5cm×1.5cm (1cm(2)-2cm(2)). Division and inset occurred on average 16days later (12-24days). Average follow-up was 6.8months (4.1-9.6months). The average total active range of motion (TAM) in flexion was 248° (235°-260°) [normal maximum: 260°]. All patients had 85° metacarpophalangeal joint (MCPJ) range of motion (ROM) [normal maximum: 85°]. The average proximal interphalangeal joint (PIPJ) ROM was 103° (95°-110°) [normal maximum: 110°] in flexion, and an average 60° distal interphalangeal (DIPJ) ROM (55°-65°) [normal maximum: 65°] in flexion. Objective sensibility in the flap was ascertained as an average static two-point discrimination of 7mm (6mm-10mm) in 10 compliant patients and was grossly intact in all other patients. There were no complications.

CONCLUSIONS

The thenar flap is a safe and effective option for pediatric fingertip amputation injuries requiring soft-tissue reconstruction.
