ABSTRACT

PURPOSE: Short-segment minimally invasive percutaneous spinal osteosynthesis has now become one of the treatments of choice to treat thoracolumbar fractures. The question of implant removal once the fracture has healed is still a matter of debate since this procedure can be associated with loss of sagittal correction. Therefore, we analyzed risk factors for kyphosis recurrence after spinal implants removal in patients treated with short-segment minimally invasive percutaneous spinal instrumentation for a thoracolumbar fracture. METHODS: A total of 32 patients who underwent implant removal in percutaneous osteosynthesis for post-traumatic thoracolumbar fracture were enrolled in our study. Patient's medical record, operative report and imaging examinations carried out at the trauma and during the follow-up were analyzed. RESULTS: Every patient experienced fracture union. Vertebral kyphotic angle (VKA) and Cobb angle (CA) improved significantly after stabilization surgery. VKA, CA, upper disk kyphotic angle (UDKA) and lower disk kyphotic angle (LDKA) significantly gradually decreased during follow-up. Traumatic disk injury (p: 0.001), younger age (p: 0.01), canal compromise (p: 0.04) and importance of surgical correction (p < 0.001) were significantly associated with kyphosis recurrence after implant removal. Anterior body augmentation did not affect loss of correction (CA and VKA) during the follow-up period (p: 0.57). CONCLUSION: Despite correction of the fracture after stabilization, we observed a progressive loss of correction over time appearing even before implant removal. Particular attention should be paid to post-traumatic disk damage or canal invasion, to young patients and to surgical overcorrection of the traumatic kyphosis.

ABSTRACT

PURPOSE: To assess the viability and effectiveness of mono-segmental percutaneous screw fixation in the treatment of unstable type B thoracolumbar fracture due to ankylosing spondylitis. METHODS: We report here all 40 patients treated by mono-segmental screw fixation in this indication, between January 2018 and January 2022, with follow-up at 3 and 9 months. Study variables comprised operating time, length of stay, fusion, stabilization quality, and peri-operative morbidity and mortality. RESULTS: One patient showed early displacement of rods caused by technical error. None of the others showed secondary displacement of rods or screws. Mean age was 73 years (range 18-93), mean hospital stay 4.8 days (range 2-15), mean operative time 52minutes (range 26-95minutes) and mean estimated blood loss 40ml. There were 2 deaths caused by intensive care unit complications. All patients except those in intensive care were verticalized within 24hours after surgery. Parker score was unchanged for each patient before and after surgery and during follow-up. CONCLUSION: Mono-segmental percutaneous screw fixation in the treatment of unstable type B thoracolumbar fracture due to ankylosing spondylitis was safe and effective. This study showed that this surgery reduced length of hospital stay, operative time, blood loss and complications compared to open or extended percutaneous surgery, and allowed fast rehabilitation in this vulnerable population.

ABSTRACT

OBJECTIVE: Surgery is an effective treatment for drug-resistant temporal-lobe epilepsy (TLE), but is still underutilized for older patients because of a perceived higher rate of perioperative complications, cognitive decline and worse seizure outcome. METHODS: We retrospectively screened all patients operated on in our institution for drug-resistant TLE between 2007 and 2019. Data of patients aged ≥50 years versus <50 years at surgery were compared. The primary endpoint was freedom from disabling seizure (Engel I) at 2 years postoperatively. RESULTS: In patients aged ≥50 years (n=19), mean age at surgery was 54.9 years and mean disease duration was 36.6 years. At 2 years postoperatively, rates of Engel I seizure outcome were not significantly different between the two groups (73.9% in the <50 years group versus 94.4% in the ≥50 years group). Although surgical complications were significantly (47.4%) in the older patients, neurological deficit was permanent in only 5.3% of cases. At 1 year postoperatively, neuropsychological outcome did not significantly differ between the two groups. CONCLUSIONS: Patients aged ≥50 years had an excellent seizure outcome at 2 years postoperatively. Early postoperative complications were more frequent in patients aged ≥50 years but were mostly transient. Cognitive outcome was similar to that in younger patients. These findings strongly suggest that age ≥50 years should not be an exclusion criterion for resective epilepsy surgery in patients with drug-resistant TLE.

ABSTRACT

OBJECTIVE: The aim of this study was to share a single center's experience of prenatal neurosurgical counseling and explore pregnant women's experiences with counseling. MATERIAL AND METHODS: This retrospective study analyzed data for 81 women who received prenatal counseling in a single institution (same senior pediatric neurosurgeon) over a 6-year period. Additionally, a retrospective questionnaire study was conducted with 33 women who chose to continue their pregnancy, to assess the strengths and weaknesses of counseling and analyze the reasons for their decision. RESULTS: Spinal dysraphism was the most frequent condition leading to prenatal counseling, followed by conditions affecting the cerebrospinal fluid. 57.6% of the women did not follow the French national recommendations on folic acid supplementation in the periconceptional period, and 38.3% underwent termination of pregnancy (TOP). One-third of the 33 women who answered our questionnaire changed their mind about TOP after counseling, and 50% reported that the information provided influenced their decision. CONCLUSION: Prenatal neurosurgical counseling is nowadays an important part of a pediatric neurosurgeon's practice. It provides specific information to the woman to decide whether to continue the pregnancy. Urological concerns are frequent among the malformations encountered. Hence, we conclude that these women should be offered the possibility of seeing a urologist. Areas for improvement include greater awareness regarding folic acid supplementation and improved psychological care. The advantage for a woman of consulting a neurosurgeon consists in receiving information that is as accurate as possible about the level of disability of the future child and about surgery and follow-up.
