Femoral shaft fractures are major life- and limb-threatening injuries. Such injuries, when neglected for months or years, can lead to a range of debilitating consequences. In the Indian subcontinent, there are multiple such cases that are presented to tertiary care hospitals late due to a lack of awareness and low socioeconomic constraints. These neglected cases on presentation are usually in a state of nonunion or malunion, with gross shortening and deformity affecting adjacent joint mobility. The management of neglected femur shaft fractures (NFFs) demands uphill tasks, such as achieving mechanical stability, restoring length and alignment, and having strong rehabilitation schedules. The functional outcomes of these cases are always not proportional to their radiological counterparts and must be taken care of separately. In this study, intramedullary nailing of the fracture after initial distraction with the Ilizarov fixator aims to reduce deformity and shortening while restoring near-optimal functional life. The study aimed to evaluate the functional and radiological outcomes of NFFs operated with distraction by an Ilizarov fixator followed by intramedullary nailing.
Methods: Fourteen cases of NFFs presented to Kalinga Institute of Medical Sciences, Bhubaneswar, India, between January 2020 and June 2022 were recruited for the study. After preoperative evaluation and explanation of available treatment options to patients, they were operated on with a two-stage procedure of Ilizarov fixator application, followed by intramedullary interlocking nailing, with a period of gradual distraction in between. They were then followed up for a minimum of 12 months to assess functional and radiological outcomes.
Results: The average time for all of the fractures to heal was 25.2 weeks. The average knee flexion increased from 28.2 degrees before surgery to 87.1 degrees after surgery. All 14 patients could walk with complete weight bearing on the operated limb postoperatively after proper pain control measures were taken. The mean Tegner Lysholm knee score was 77.8. There was residual limping in six of the cases, which could be attributed to muscle atrophy and/or shortening in the affected limbs. In three cases, skin blisters were formed due to the acute nature of the distraction, but they all healed with a scab and scar, otherwise uneventfully. The shortening, in 13 cases, came down to 4 cm or less, which was managed with a shoe raise. The one case with a residual 5 cm shortening had a short, limping gait, and it was attributed to an extremely overriding osteopenic femur preoperatively.
Conclusion: A two-stage operation with distraction by an Illizarov fixator followed by an intramedullary fixation provides the basic advantage of not having to excise an excessive amount of bone, which may be required in primary open reduction and intramedullary fixation. It also allows the patient to carry on his daily activities as mobilization is not restricted, which is the case in an individual to whom skeletal traction is applied. Hence, in any NFF case, this algorithm of management can be considered a frontrunner in the comprehensive management of disability and deformity.
