Clinical and radiological evaluation of minimally invasive intramedullary fixation by titanium elastic nails in paediatric long bone fractures of lower limb: a prospective study

Abstract

<p class="abstract"><strong>Background:</strong> Elastic stable intramedullary nailing for the treatment of paediatric femur and tibial diaphyseal fractures was introduced by Prevot and colleagues in 1979. It follows three-point fixation principle that provides internal support in presence of cortical contact and an intact soft-tissue envelope. This technique has many advantages, including better reduction, dynamic axial stabilization, shorter hospitalization with early rehabilitation and low complication rate.</p><p class="abstract"><strong>Methods:</strong> This is a prospective observational study done at Kauvery Medical Centre, Trichy between May 2017 to May 2018 consisting of 39 children between age 5 to 16 years with diaphyseal fractures of femur and tibia. The fractures were treated by closed reduction and internal fixation with titanium elastic intramedullary nailing. The patients were evaluated clinically and radiologically and followed for an average of 6 months. Outcome was assessed using transcutaneous electrical nerve stimulation (TENS) scoring system used by Flynn et al.<strong></strong></p><p class="abstract"><strong>Results:</strong> Our series consisted of 39 patients (22 cases with fracture shaft of femur and 17 cases with fracture shaft of tibia), 33 males and only 6 females. Average time for radiological union was 9.89 weeks. All patients had full range of hip and ankle motion and 2 (5.1%) patients had mild restriction in knee flexion at 12 weeks.</p><p class="abstract"><strong>Conclusions:</strong> Elastic stable intramedullary nailing is an ideal method for treatment of paediatric femoral and tibial diaphyseal fractures due to lower complication rate and good functional outcome in comparison to other methods of treatment.</p>
