RESUMEN
Chronic subdural hematomas (CSDH) are increasingly prevalent, especially among the elderly. Surgical intervention is essential in most cases. However, the choice of surgical technique, either craniotomy or burr-hole opening, remains a subject of debate. Additionally, the risk factors for poor long-term outcomes following surgical treatment remain poorly described. This article presents a 10-year retrospective cohort study conducted at a single center that aimed to compare the outcomes of two common surgical techniques for CSDH evacuation: burr hole opening and minicraniotomy. The study also identified risk factors associated with poor long-term outcome, which was defined as an mRS score ≥ 3 at 6 months. This study included 582 adult patients who were surgically treated for unilateral CSDH. Burr-hole opening was performed in 43% of the patients, while minicraniotomy was performed in 57%. Recurrence was observed in 10% of the cases and postoperative complications in 13%. The rates of recurrence, postoperative complications, death and poor long-term outcome did not differ significantly between the two surgical approaches. Multivariate analysis identified postoperative general complications, recurrence, and preoperative mRS score ≥ 3 as independent risk factors for poor outcomes at 6 months. Recurrence contribute to a poorer prognosis in CSDH. Nevertheless, use burr hole or minicraniotomy for the management of CSDH showed a similar recurrence rate and no significant differences in post-operative outcomes. This underlines the need for a thorough assessment of patients with CSHD and the importance of avoiding their occurrence, by promoting early mobilization of patients. Future research is necessary to mitigate the risk of recurrence, regardless of the surgical technique employed.

PURPOSE: Coronal balance is a major factor impacting the surgical outcomes in adult spinal deformity (ASD). The Obeid coronal malalignment (O-CM) classification has been proposed to improve the coronal alignment in ASD surgery. Aim of this study was to investigate whether a postoperative CM < 20 mm and adherence to the O-CM classification could improve surgical outcomes and decrease the rate of mechanical failure in a cohort of ASD patients. METHODS: Multicenter retrospective analysis of prospectively collected data on all ASD patients who underwent surgical management and had a preoperative CM > 20 mm and a 2-year follow-up. Patients were divided in two groups according to whether or not surgery had been performed in adherence to the guidelines of the O-CM classification and according to whether or not the residual CM was < 20 mm. The outcomes of interest were radiographic data, rate of mechanical complications and Patient-Reported Outcome Measures. RESULTS: At 2 years, adherence to the O-CM classification led to a lower rate of mechanical complications (40 vs. 60%). A coronal correction of the CM < 20 mm allowed for a significant improvement in SRS-22 and SF-36 scores and was associated with a 3.5 times greater odd of achieving the minimal clinical important difference for the SRS-22. CONCLUSION: Adherence to the O-CM classification could reduce the risk of mechanic complications 2 years after ASD surgery. Patients with a residual CM < 20 mm showed better functional outcomes and a 3.5 times greater odd of achieving the MCID for the SRS-22 score.

BACKGROUND: Surgical site infection (SSI) after thoracolumbar osteosynthesis is a common complication. Its management relies on surgical revision and antibiotic therapy, but treatment failure is not uncommon. The aim of our study was to assess the frequency of SSI management failure and its risk factors. METHODS: A retrospective study of patients hospitalized from 2011 to 2019 at the University Hospital of Caen was carried out. The infection rate and the time to onset of failure were assessed over a minimum follow-up of 1 year. Treatment failure was defined as the occurrence of a new intervention in the spine in the year following the end of antibiotic therapy, the establishment of long-term suppressive antibiotic therapy, or death from any cause within 1 year of the end of antibiotic therapy. We compared the treatment failure group with the treatment success group to determine risk factors for treatment failure. RESULTS: A total of 2881 patients underwent surgery during the study period, and 92 developed an SSI, corresponding to an SSI rate of 3.19%. Thirty-six percent of the patients with an SSI presented treatment failure. The median time to failure was 31 days. On multivariate analysis, diabetes mellitus was identified as a risk factor for treatment failure, whereas prolonged postoperative drainage for 4 to 5 days was a protective factor. CONCLUSIONS: The number of failures was significant, and failure occurred mainly during the early phase. To decrease the risk of treatment failure, prolonged duration of postoperative drainage seems to be helpful. Additionally, as diabetes is a risk factor for treatment failure, good control of glycemia in these patients might impact their outcomes.

OBJECTIVES: The aims of the present study were to evaluate the frequency of late recurrence after chronic subdural hematoma (CSDH) evacuation and to examine the interest in the use of a systematic CT scan within the first two months after surgery. PATIENTS AND METHODS: We performed a retrospective study that included all patients who underwent CSDH evacuation between 2007 and 2017. We evaluated the rate of late recurrence, defined as the need to perform a new surgery after the first month of follow-up. All the patients underwent a clinical examination and a systematic CT scan between one and 2 months after the first surgery (delayed systematic CT scan). We evaluated the rate of clinical recurrence, defined as the association between clinical symptoms and radiological abnormalities, and of radiological recurrence, defined only on CT scan data. RESULTS: During the inclusion period, 696 patients underwent CSDH evacuation in our unit. Overall, 54 patients (7.7%) had recurrence, of whom 21 (39%) had recurrence after 4 weeks (late recurrence). Of the 21 patients with late recurrence, 7 (1%) had radiological recurrence, and 14 (2%) had clinical recurrence. There was no difference in the CT scan characteristics between patients with clinical and radiological recurrence. CONCLUSION: The use of a delayed systematic CT scan after CSDH surgery has a marginal impact on patient management, and the indication for reoperation without symptoms seems highly subjective. In patients without neurological symptoms, the use of a delayed cerebral CT scan may not be indicated.
