Abstract:
Objective:To analyze the curative effect of locking compression pediatric hip plate (LCH-PHP) in the treatment tumor-like lesions of femoral neck in children.Methods:From January 2012 to June 2019, 45 children with Erol type Ⅱ-Ⅳ tumor-like lesions of femoral neck were retrospectively analyzed, involving 32 males and 13 females, aged 2-14 years.Among them, 27 cases were simple bone cyst, 15 cases were fibrous dysplasia, 3 cases were Langerhans histiocytosis, and 17 cases were accompanied with pathological fracture.Patients without pathological fracture were divided into 2 groups according to different surgical methods: lesion removal and bone grafting+ LCH-PHP preventive fixation group (group A) and lesion removal and bone grafting group (group B). Patients with pathological fracture were divided into 2 groups according to the different surgical methods: lesion removal and bone grafting+ LCH-PHP fixation and reduction group (group C) and lesion removal and bone grafting group (group D). The loss of femoral neck-stem angle, healing time and Musculoskeletal Tumor Society (MSTS) scores were compared between group A and group B. Changes of femoral neck-stem angle were compared between group C and group D at postoperative 1 day and the last follow-up.Results:Forty-five patients were followed up for an average of 2.6 (1-4) years.The loss of femoral neck-stem angle in group A and group B were (0.50 ± 0.45)°, and (2.26 ± 1.64)°, which was significantly different ( t=-3.193, P<0.05). There were no significant differences in the healing condition, healing time and MSTS scores at the last follow-up between group A and group B(all P>0.05). In group C, the ipsilateral femoral neck-stem angle at the postoperative 1 day and the last follow-up were (133.67±4.53)°and (133.00±4.32)°, respectively, which was comparable ( P>0.05). In group D, the ipsilateral femoral neck-stem angle at the postoperative 1 day and the last follow-up were (133.36±7.82)°and (130.63±8.24)°, respectively, which was significantly different ( t=7.11, P<0.05). Conclusions:LCH-PHP fixation can effectively maintain the femoral neck-stem angle and prevent the occurrence of pathological fracture children with Erol Ⅱ-Ⅳ tumor-like lesions of femoral neck.
