Objective:To investigate the clinical efficacy of intramedullary nailing combined with bone cement in repair of segmental bone defects after tumor resection.Methods:A retrospective analysis was conducted of the 5 patients with malignant bone tumor who had been treated at Department of Orthopaedics, Qiannan People's Hospital from April 2018 to September 2019 for remaining segmental bone defects following limb salvage surgery. They were 4 males and one female, aged from 11 to 55 years (average, 35.4 years). Their defects ranged from 6 to 21 cm (average, 12.3 cm) after tumor resection. By the Karnofsky performance score (KPS) for long-term quality of life, all of them scored less than 50 points. Of them, 3 were treated by interlocking intramedullary nails and bone cement filling, and 2 by elastic intramedullary nails and bone cement filling. In the 2 cases with defects of 21 cm and 13 cm, the fixation was assisted by a plate and an external fixator. Defect length after resection, operation time and intraoperative bleeding were recorded; the efficacy was evaluated by the Enneking functional evaluation of reconstructive procedures after surgical treatment of tumors of the musculoskeletal system, visual analogue scale (VAS), and KPS.Results:All the 5 patients had uneventful surgery, with operation time ranging from 112 to 225 min (average, 154.2 min), intraoperative bleeding from 300 to 500 mL (average, 382 mL), and defect length after resection from 6 to 21 cm. The 5 patients were followed up for 6 to 28 months. Of them, 2 died of disease progression 6 and 7 months after surgery, respectively. According to the Enneking's evaluation, one patient scored 28 points, 2 patients 23 points and 2 patients 21 points, giving a high degree of satisfaction. Their VAS scores 6 months after surgery ranged from 1 to 6, averaging 3.6; their postoperative KPS scores ranged from 60 to 80, averaging 72.Conclusion:In repair of segmental bone defects after tumor resection, intramedullary nailing combined with bone cement filling can relieve pain of patients and lead to satisfactory short-term curative efficacy.
