[Hidden posterior tibial tendon dislocation after ankle sprain: case report]. / Luxación del tendón tibial posterior oculta tras un esguince de tobillo: reporte de caso.

INTRODUCTION: traumatic posterior tibial tendon dislocation is a rare entity that can go unnoticed in our usual clinical practice. MATERIAL AND METHODS: a 31-year-old man, with no relevant medical history, suffered a high-energy traffic accident. He presented a dislocation of the posterior tibial tendon that went unnoticed. After an early diagnosis, a primary repair of the flexor retinaculum was performed and the anatomical reduction of the tendon was achieved. RESULTS: the patient was able to resume sports activity three months after the injury with good functional results. CONCLUSIONS: we should suspect this entity after high-energy trauma with ankle sprains. Surgical treatment of this lesion offers good functional results.

INTRODUCCIÓN: la luxación traumática del tendón tibial posterior es una entidad poco frecuente que puede pasar desapercibida en nuestra práctica clínica habitual. MATERIAL Y MÉTODOS: un hombre de 31 años, sin antecedentes médicos de interés, sufrió un accidente de tráfico de alta energía. Presentaba una luxación del tendón tibial posterior que pasó desapercibida. Tras un diagnóstico precoz se consiguió realizar una reparación primaria del retináculo flexor y se logró la reducción anatómica del tendón. RESULTADOS: el paciente pudo retomar la actividad deportiva a los tres meses de la lesión con buen resultado funcional. CONCLUSIONES: debemos sospechar esta entidad tras un traumatismo de alta energía con entorsis de tobillo. El tratamiento quirúrgico de esta lesión ofrece buenos resultados funcionales.

[Translated article] Sagittal imbalance influences outcome of vertebroplasty in patients with osteoporotic vertebral compression fracture.

BACKGROUND AND OBJECTIVES: The correlation between sagittal balance of the spine and clinical outcome after vertebroplasty (VP) in patients with osteoporotic vertebral compression fractures (OVCF) is poorly investigated. We analysed the clinical outcome of patients with OVCF undergoing VP taking into account sagittal balance. METHODS: The primary endpoint was the change in axial back pain; disability and health-related quality of life using VAS, ODI and SF-36 respectively in correlation to the parameters that define sagittal balance (SVA). Radiographic assessment included full spine standing lateral films. Imaging and clinical data were collected pre and post procedure at 1, 3 and 12 months. RESULTS: Fifty-one patients were included presenting a total of 113 OVCF. Thirty patients (60.7%) had multiple OVCF. Comparing the evolution of VAS and ODI throughout the follow-up it does not seem that there are significant differences in their behaviour between the SVA>50mm and the SVA<50mm groups (p>0.05). On the contrary, preVP SF-36 scores showed worst results in the SVA>50mm group in the physical functioning section (PF) (p<0.05) and in the physical component score (PCS) (p<0.05). These differences were maintained until 3 months of follow-up in the case of the PCS and until the end of follow-up in the case of the PF (p<0.05). CONCLUSIONS: Patients with a SVA>50mm showed a slower recovery of their quality of life after VP for OVCF, but without significant differences with respect to pain or disability, when compared with patients with SVA<50mm.

BACKGROUND AND OBJECTIVES: The correlation between sagittal balance of the spine and clinical outcome after vertebroplasty (VP) in patients with osteoporotic vertebral compression fractures (OVCF) is poorly investigated. We analysed the clinical outcome of patients with OVCF undergoing VP taking into account sagittal balance. MATERIAL AND METHOD: The primary endpoint was the change in axial back pain, disability and health-related quality-of-life using Visual Analogue Scale (VAS), Oswestry Disability Index (ODI) and SF-36, respectively, in correlation to the parameters that define sagittal balance (SVA). Radiographic assessment included full spine standing lateral films. Imaging and clinical data were collected pre- and post-procedure at 1, 3 and 12 months. RESULTS: 51 patients were included presenting a total of 113 OVCF. 30 patients (60.7%) had multiple OVCF. Comparing the evolution of VAS and ODI throughout the follow-up it does not seem that there are significant differences in their behaviour between the SVA>50mm and the SVA<50mm groups (p>0.05).

These differences were maintained until 3 months of follow-up in the case of the PCS and until the end of follow-up in the case of the PF (p<0.05). CONCLUSIONS: Patients with a SVA>50mm showed a slower recovery of their quality-of-life after VP for OVCF, but without significant differences with respect to pain or disability, when compared patients with SVA<50mm.
