동통을 동반한 주상골 부골에 대한 단순 골 절제술과 골 절제 및 후 경골 건 전진술간의 방사선학적 결과 비교 = Comparison of Radiographic Results from Simple Bone Excision and Bone Excision with Advancement of Posterior Tibial Tendon for Painful Prehallux

다국어 초록 (Multilingual Abstract)

Purpose: To analyze the radiographic results between the simple bone excision and simple bone excision and posterior tibial tendon advancement for prehallux. Materials and Methods: Thirty-four patients who underwent operative treatment for prehallux between 1995 and 2000 were reviewed. Twenty-six patients who underwent simple bone excision and posterior tibial tendon advancement and eight patients who underwent simple bone excision were available for follow-up. Follow-up averaged 44 months(15-59 months). We evaluated and compared the cuboidal height and the talo-1st metatarsal angle in the preoperative and postoperative radiography. Results: The average span of disappearing pain is 3.7 months(2-7 months) after the operation. Mean cuboidal height and talo-1st metatarsal angle were increased $6.7{\pm}1.8mm$, $5.0{\pm}2.1^{\circ}$ before to $7.8{\pm}0.2mm$, $5.6{\pm}0.7^{\circ}$ after simple bone excision and posterior tibial tendon advancement. Mean cuboidal height and talo-1st metatarsal angle were increased $6.6{\pm}0.7mm$, $4.6{\pm}1.1^{\circ}$ before to $7.7{\pm}0.9mm$, $5.1{\pm}0.4^{\circ}$ after simple bone excision and posterior tibial tendon advancement. One case of extra-osseous migration of the Mitek anchor inserted into navicula was seen during the follow-up period. Conclusion: This study shows that the remarkable differences between the two procedures are not found. So, simple bone excision without advancement of posterior tibial tendon for prehallux can generate relatively good results.
