Epilepsy is the common neurological disease, and antiepileptic drugs are the main means for the treatment of epilepsy. However, there is no conclusion on the timing of drug withdrawal in patients with epilepsy. In recent years, some large-scale prospective studies have provided some guidance on anti-epileptic drugs withdrawal. This article focused on the factors affecting the prognosis and timing of drug withdrawal, hoping to further the understanding of anti-epileptic drugs withdrawal and instruct clinical practise.

Objective To investigate the anatomical features, operative method and efficacy of internal fixation in the treatment of iutra-articular fractures of caleaneum via the sinus tarsi approach. Methods The pathway, branches distribution and anastomosis of perforating descending branch of peroneal artery were observed on 18 adult cadaveric lower limbs. A sinus tarsi approach was designed. From July 2001 to January 2008, 71 intra-articular calcaneal fractures in 68 patients were treated with open reduction and internal fixation via sinus tarsi approach at lateral sides of calcaneus. According to the Sanders classification, there were 26 type Ⅱ fractures, 32 type Ⅲ fractures and 13 type Ⅳ fractures. Results All patients were followed up for a mean period of 39.3 months (13-85 months), and the fractures were completely healed. There was a significant difference in the length, width and height of the calcaneus, Bohler angle and Gissane angle before and after operation (P < 0.01). According to Maryland Foot Score, the operative effect was excellent in 33 feet, good in 29 feet, fair in 6 feet and poor in 3 feet. Conclusion Open reduction and internal fixation via sinus tarsi approach is an effective method for minimally invasive treatment of intraarticular fractures of the calcaneus, with the advantages of good clinical results and causing minimal damage to soft tissues.

OBJECTIVETo evaluate the clinical effects of percutaneous pedicle screw fixation(PPSF) combined with percutaneous vertebroplasty(PVP) for the treatment of osteoporotic thoracolumbar fractures.
METHODSThe clinical data of 94 patients with osteoporotic thoracolumbar fractures treated from January 2014 to December 2015 were retrospectively analyzed. There were 31 males and 63 females, aged from 65 to 70 years old with an average of 67.2 years. Fracture level was T₁₁ on 15 cases, T₁₂ on 32 cases, L₁ on 29 cases and L₂ on 18 cases. The patients were divided into two groups according to different therapeutic methods. Percutaneous pedicle screw fixation combined with percutaneous vertebroplasty were applied in 43 patients(group A) and percutaneous vertebroplasty was applied to 51 patients(group B). Operation time, intraoperative blood loss, bone cement volume, postoperative in-bed time were recorded; preoperatively, 3 d, 1 year after the operation, the ratios of anterior border heights, sagittal Cobb angles, visual analogue scale(VAS) scores were compared between two groups. The condition of postoperative complication in two groups was analyzed.
RESULTSAll the patients were followed up for 12 to 24 months with an average of 18.5 months. Operation time of group A [(96.2±28.7) min] was longer than that of group B [(31.8±10.6) min]. Intraoperative blood loss of group A[(62.2±25.5) ml] was more than that of group B [(25.4±10.9) ml]. Bone cement volume of group A [(5.5±0.5) ml] was larger than that of group B [(4.9±1.1) ml]. Postoperative in-bed time of group A[(5.1±1.8) d] was longer than that of group B[(1.8±0.7) d]. There were significant differences in operation time, intraoperative blood loss, bone cement volume, postoperative in-bed time between two groups(<0.05). Three days, 12 months after the operation, the ratios of anterior border heights and Cobb angles in two groups were significantly improved. At final follow-up, the ratio of anterior border height and Cobb angle of group A[(85.6±3.5)%, (11.9±5.3)°] were better than of group B[(84.2±4.5)%, (15.3±3.4)°](<0.05). Three cases in group B had re-collapse of cemented vertebral bodies. Postoperative at 3 d, 1 year, VAS score of all patients had significantly decreased(<0.05), and there was no significant difference between two groups(>0.05).
CONCLUSIONSCompared to simple PVP, PPSF combined with PVP in treating osteoporotic thoracolumbar fracture can obtain stronger vertebral strength and stiffness, furthermore to improve vertebral reduced effect, keeping vertebral heights, and preventing vertebral re-collapse.
