?Presentan inestabilidad lateral de tobillo del pacientes luego de la resección del os trigonum por vía artroscópica posteriro?

Abstract

lntroduction: Evaluate residual lateral ankle instability after arthroscopic resection of the os trigonum. Material and method: 29 ankles with a diagnosis of os trigonum. Average 27 years old (R=17-36).21 men, 8 women. The median follow-up was 35 months.(R= 14-62).The AOFAS and Short Form 36 score were use in the postoperative evaluation. We performed stress x-rays (drawer and tilt test) pre-and post-treatment of both ankles. Results: The average A0FAS score was 95 (R = 90-100) while the 36 SF presented an excellent result in all cases except 1 in which the patient continued with pain, without subjective or objective instability.Stress x-rays showed an anterior yawn average of 2,6 mm (R= 0, 63 mm) and external yawn an average of 12 deg rees (R = 4-17) without significant contra late ral an kle x-ray. Conclusion: Patients after poste rior ankle arthroscopy didn't present subjetive or objetive instability. The stress x-ray showed no significant differences with pretreatment and the contralateral x-ray. All patients return to sports in the same way than before the surgery. Results: The average A0FAS score was 95 (R = 90-100) while the 36 SF presented an excellent result in all cases except 1 in which the patient continued with pain, without subjective or objective instability. Stress x-rays showed an anterior yawn average of 2,6 mm (R - 0, 63 mm) and external yawn an average of 12 degrees (R - 4-17) without significant differences (P>0.05) with pretreatment injured ankle and contralateral ankle x-ray. Conclusion: Patients after posterior ankle arthroscopy didn't present subjetive or objetive instability. The stress x-ray showed no significant differences with pretreatment and the contralateral x-ray. All patients return to sports in the same way than before the surgery.
