摘要
Objective To report the results of treatment of osteoid osteomas with wide surgical excision and CT-guided less invasive surgeries.Methods Forty-two patients were entered into this prospective study between Jan.1998 and Jan.2008.Nineteen patients underwent wide surgical excision.The lesions were in the femur(n=9),tibia(n=7),and humerus(n=3).The mean lesion diameter was(9.2±2.3)mm(range,7-16mm).Twenty-three patients(15 males and 8 females)underwent CT-guided less invasive surgeries procedures.The lesions were in the femur(n=9),tibia(n=6),acetabulum(n=4)and humerus(n=4).The mean lesion diameter was(8.1±2.7)mm(range,6-15mm).Among these 23 patients,20 patients were performed by core drill excision.Three patients were performed by radiofrequency ablation.Follow-up ranged from 16 to 68 months(mean,35 months)to assess pain,neurovascular damage,pathological fracture,movement,and recurrence.Results were categorized as success(persistent complete relief of pain)and failure(absent or incomplete relief of pain,requiring additional treatment).Results The success rates were 89%(17/19)after wide surgical excision and 96%(22/23)after less invasive surgeries,respectively,and the difference was not significant(P>0.05).Patients were hospitalized for average 8.3 d(5-15d)after wide surgical excision and 3.2d(3-5d)after less invasive surgeries(P<0.05).There were no complications such as sepsis,pathological fracture,or neurovascular damage.No further recurrences were observed during follow-up.Conclusion Less invasive surgeries has obvious advantages such as reduced cost,shorter stay in hospital and rapid convalescence.Core-drill excision can obtain sufficient material for pathologic examination.
