- Abstract:
- Objective To explore the related influencing factors of the prognosis of proximal femoral unicameral bone cyst (UBC) in children.Methods From January 2016 to September 2022,retrospective analysis was performed for the relevant clinical data of 25 children with proximal femoral UBC undergoing continuous drainage and decompression with titanium elastic intramedullary nail (TEN).Among them,15 cases developed concurrent pathological fractures.Gender,age,lesion sideness,cystic nature,cystic index,presence of pathological fractures,number of TEN implants and regular postoperative radiographic follow-ups were recorded.Capanna evaluation criteria were utilized for assessing postoperative healing.Partial healing,recurrence and no response during follow-ups were classified as poor prognosis group while complete healing of cysts good prognosis group.Gender,age,lesion sideness,cystic nature,cystic index,pathological fracture status and TEN quantity were compared.Results Average follow-up period was 40(18-80) months.At the last follow-up,there were 16 cases in good prognosis group (complete healing) and 9 cases in poor prognosis group (7 cases partially healed,1 case no response and 1 case relapsing).Effective rate of treatment was 92%(23/25) (complete/partial healing deemed as effective treatment).Univariate analysis revealed that static lesions healed better (P<0.05); the smaller cystic index,the better healing (P<0.05).Multivariate Logistic regression analysis indicated that cystic index (OR=0.005,95%CI:0.000-0.870) was an independent correlation factor (P<0.05) for healing of proximal femoral UBC in children.Conclusions Healing of proximal femoral UBC in children is correlated with cystic index.The smaller cystic index,the better healing.And conversely,the worse healing.TEN implanting for continuous drainage and decompression is both effective and safe for proximal femoral UBC in children.
