Surgical management of adult spinal deformities remains challenging, and one of the major goals is to restore sagittal alignment. Spinal rods used for posterior fixation are usually delivered straight and bended manually during surgery. This manual bending can be responsible for undercorrection of the deformity. In the last years, prebended patient-specific rods have been developed and might be a valuable tool in order to optimize surgical results. The objective is therefore to use the time between surgical decision and operative room in order to realize a precise surgical planning and obtain patient-specific rods. We describe here the planning process and our preliminary experience with patient-specific rods in the management of adult deformity about 77 cases. On the 77 cases, PSR were used without further modifications of the shape. Based on 3-month postoperative evaluation, a significant decrease of sagittal vertical axis (−41%, p<0.0001) and pelvic incidence-lumbar lordosis (−62%, p<0.0001) was reported. Pelvic tilt was not significantly corrected, except in patients with Parkinson’s disease. In this subgroup of patients, measurements revealed a significant correction of SVA and PI-LL (−53%, p=0.005, and −81%, p<0.0001, respectively) but also of PT (−23%, p<0.001). The use of PSR, in our experience, was feasible and provided satisfactory short-term results. It can be a valuable tool in the management of adult spinal deformities. Further studies will be needed in order to confirm these preliminary results.

Most of tuberculum sellae meningiomas (TSM) show asymmetric growth. They are usually resected through ipsilateral approaches. The access of the inferior-medial side of the ipsilateral optic nerve might be challenging, which result in increased manipulation of the compromised optic nerve. The contralateral approach has been described to avoid these technical difficulties. Assessing the long-term visual and olfactory outcome, as well as recurrence rate in patients operated for TSM through ipsilateral or contralateral approaches. Single center retrospective cohort study about 94 patients operated on between March 2000 and April 2018. Seventy percent of the preoperative visual acuity loss totally resolved (44%) or showed varying degrees of improvement (26%) after surgery. Seventy-two percent of the preoperative visual field defects evolved favorably (44% recovery, 28% improvement). Eight patients showed aggravated visual disturbances (9%). A contralateral approach seemed to be predictive of visual field defects improvement after surgery (OR = 0.4), with borderline significant results (p = .08). There was a higher rate of postoperative olfactory nerve impairment after a contralateral approach (37% vs 17%, p = .03). Total removal of the tumor fragment entering the optic canal was accomplished in 96% in the contralateral vs 75% in the ipsilateral group (p = .04). The 2-, 5-, and 7-year tumor progression-free survival were 100% in the Simpson grade 2 group, and 85% (n = 17), 74% (n = 11), and 67% (n = 5) in the Simpson grade 4 group, respectively (p = .00). Resection of tuberculum sellae meningiomas through a contralateral approach seems to provide better visual outcome and tumor control at the cost of increased olfactory nerve disorders.

Chronic subdural hematoma (CSDH) is a common condition necessitating surgery; however, recurrence occurs in 15–25% of cases despite surgical management. The HEMACORT trial was a prospective randomized, double-blind, placebo-controlled, multi-centric study (NCT01380028). The aim of this trial was to determine the effect of corticosteroids as an adjuvant treatment to surgery on CSDH recurrence at 6 months. After surgery, participants were assigned by block-randomization to receive either placebo or oral prednisone at a dose of 1 mg/kg/day followed by weekly stepwise tapering in steps of 10 mg/day. The primary outcome was CSDH recurrence, defined by the need for reoperation and/or radiological progression of CSDH. Secondary outcomes were one-year death, radiological changes, safety, neurological status, and quality of life. The trial was discontinued at midpoint of expected inclusions: 78 participants received prednisone and 77 received placebo controls. In an intention-to-treat analysis, CSDH clinicoradiological recurrence was not different between prednisone and placebo groups (21.8% vs. 35.1%, respectively; hazard ratio 0.56; 95% confidence interval 0.30–1.02; p = 0.06), although post hoc analyses concluded to statistical significance ( p = 0.02). Earlier radiological resolution was observed after prednisone administration, but reoperation rates (reaching 5.8% overall) and functional outcomes were not different at 6 months. Among adverse events, sleep disorders occurred more often in the prednisone group (26.1% vs. 9.1%, p = 0.02). The HEMACORT trial data suggest that prednisone, as an adjuvant treatment to surgery, may reduce early radiological recurrence of CSDH, although clinical benefits are unclear. In view of these findings, the authors suggest that shorter treatment duration should be assessed for safety and efficacy in future trials.

Background: Spinal metastasis is becoming more frequent. This raises the topics of pain and neurological complications, which worsen the functional and survival prognosis of oncological population patients. Surgical treatment must be as complete as possible in order to decompress and stabilize without delaying the management of the oncological disease. Minimally invasive spine surgical techniques inflict less damage on the musculocutaneous plan than opened ones. Methods: Different minimally invasive techniques are proposed in this paper for the management of spinal metastasis. We used our experience, developed degenerative and traumatic pathologies, and referred to many authors, establishing a narrative review of our local practice. Results: Forty-eight articles were selected, and these allowed us to describe the different techniques: percutaneous methods such as vertebro/kyphoplasty, osteosynthesis, mini-open surgery, or that through a posterior or anterior approach. Also, some studies detail the contribution of new technologies, such as intraoperative CT scan and robotic assistance. Conclusions: It seems essential to offer a lasting solution to a spinal problem, such as in the form of pain relief, stabilization, and decompression. Our department has embraced a multidisciplinary and multidimensional approach to MISS, incorporating cutting-edge technologies and evidence-based practices.
