Published: July 2023

Objectif : L’escalade de bloc indoor connaît un engouement croissant avec l’ouverture de salles dans toutes les grandes agglomérations françaises. Toutefois, cette activité n’est pas sans conséquence sur le risque traumatique. Cette étude a pour objectif de décrire une population de grimpeurs accidentés en bloc indoor et les types de lésions associées.
Matériels et méthodes : Cette étude rétrospective a été réalisée à partir des registres d’accidents de dix salles d’escalade bloc par un recueil systématique des données sur les accidentés puis par un rappel téléphonique à trois semaines.
Résultats : Cinq cent quatre-vingt-deux accidents ont été recensés entre le 1er septembre 2021 et le 28 février 2022. Les accidents avaient lieu à la réception d’une chute dans 87 % des cas et affectaient 50 % de femmes. Les localisations lésionnelles les plus fréquentes étaient la cheville (48 %), le genou (17 %) et le coude (14 %). Il existait un surrisque d’accident pour les séances de bloc non accompagnées d’un tuteur (OR = 2,23 ; p < 0,001). Parmi les 336 blessés ayant pu être rappelés, 172 (51 %) nécessitaient une immobilisation et 49 (15 %) une prise en charge chirurgicale.
Conclusion : L’incidence et la sévérité des lésions en escalade de bloc nécessitent des études ultérieures et des actions de prévention ciblées. Ce travail constitue une première étape vers la compréhension et la surveillance d’une accidentologie spécifique du bloc indoor.

OBJECTIVE
Sacroiliac joint (SIJ) dysfunction is a significant cause of back pain. Despite recent advances in minimally invasive (MIS) SIJ fusion, the fusion rate remains controversial. This study sought to demonstrate that a navigated decortication and direct arthrodesis technique in MIS SIJ fusion would result in satisfactory fusion rates and patient-reported outcomes (PROs).

METHODS
The authors retrospectively reviewed consecutive patients who underwent MIS SIJ fusion from 2018 to 2021. SIJ fusion was performed using cylindrical threaded implants and SIJ decortication employing the O-arm surgical imaging system and StealthStation. The primary outcome was fusion, evaluated using CT at 6, 9, and 12 months postoperatively. Secondary outcomes included revision surgery, time to revision surgery, visual analog scale (VAS) score for back pain, and the Oswestry Disability Index (ODI), measured preoperatively and 6 and 12 months postoperatively. Patient demographics and perioperative data were also collected. PROs over time were analyzed using ANOVA followed by a post hoc analysis.

RESULTS
One hundred eighteen patients were included in this study. The mean (± SD) patient age was 58.56 ± 13.12 years, and most patients were female (68.6% vs 31.4% male). There were 19 smokers (16.1%) with an average BMI of 29.92 ± 6.73. One hundred twelve patients (94.9%) underwent successful fusion on CT. The ODI improved significantly from baseline to 6 months (Δ7.73, 95% CI 2.43–13.03, p = 0.002) and from baseline to 12 months (Δ7.54, 95% CI 1.65–13.43, p = 0.008). Similarly, VAS back pain scores improved significantly from baseline to 6 months (Δ2.31, 95% CI 1.07–3.56, p < 0.001) and from baseline to 12 months (Δ1.63, 95% CI 0.25–3.00, p = 0.015).

CONCLUSIONS
MIS SIJ fusion with navigated decortication and direct arthrodesis was associated with a high fusion rate and significant improvement in disability and pain scores. Further prospective studies examining this technique are warranted.

Published: July 2023

OBJECTIVE
Robot-assisted pedicle screw placement in spinal fusion has been well studied. However, few studies have evaluated robot-assisted sacroiliac joint (SIJ) fusion. The aim of this study was to compare surgical characteristics, accuracy, and complications between robot-assisted and fluoroscopically guided SIJ fusion.

METHODS
A retrospective review of 110 patients with 121 SIJ fusions done at a single academic institution was conducted from 2014 to 2023. Inclusion criteria included adult age and a robot- or fluoroscopically guided approach to SIJ fusion. Patients were excluded if the SIJ fusion was part of a longer fusion construct, not minimally invasive, and/or had missing data. Demographics, approach type (robotic vs fluoroscopic), operative time, estimated blood loss (EBL), number of screws, intraoperative complications, 30-day complications, number of intraoperative fluoroscopic images (as a surrogate for radiation exposure), implant placement accuracy, and pain status at the first follow-up were recorded. Primary endpoints were SIJ screw placement accuracy and complications. Secondary endpoints were operative time, radiation exposure, and pain status at the first follow-up.

RESULTS
Ninety patients were included who underwent a total of 101 SIJ fusions, of which 78 were robotic and 23 were fluoroscopic. The mean age of the cohort at the time of surgery was 55.9 ± 13.8 years; 46 patients were females (51.1%). No difference was found in screw placement accuracy between robotic and fluoroscopic fusion (1.3% vs 8.7%, p = 0.06). Chi-square analysis of robotic versus fluoroscopic fusion found no difference in the presence of 30-day complications (p = 0.62). Mann-Whitney U-test analysis found that robotic fusion had a significantly longer operative time than fluoroscopic fusion (72.0 vs 61.0 minutes, p = 0.01); however, robot-assisted fusions involved significantly lower radiation exposure (26.7 vs 187.4 fluoroscopic images, p < 0.001). No difference in EBL was noted (p = 0.17). No intraoperative complications were present in this cohort. Subgroup analysis comparing the 23 most recent robotic cases against the 23 fluoroscopic cases found that robotic fusion still was associated with significantly longer operative times than fluoroscopic fusion (74.0 ± 26.4 vs 61.0 ± 14.9 minutes, respectively; p = 0.047).

CONCLUSIONS
SIJ screw placement accuracy did not significantly differ between robot-assisted and fluoroscopic SIJ fusion. Complications overall were low and similar between the two groups. The operative time was longer with robotic assistance, but there was markedly less radiation exposure to the surgeon and staff.
Bilateral sacroiliac joint fusion in long constructs using self-harvesting porous S2–alar iliac screws with an integrated tulip: technical considerations and early clinical and radiographic experience

Published: July 2023

OBJECTIVE
The incidence of sacroiliac joint (SIJ) dysfunction after lumbosacral fusion is high. Upfront bilateral SIJ fusion using novel fenestrated self-harvesting porous S2–alar iliac (S2AI) screws could reduce the incidence of SIJ dysfunction and need for subsequent SIJ fusion. In this study, the authors report their early clinical and radiographic results of SIJ fusion using this novel screw.

METHODS
The authors began using self-harvesting porous screws in July 2022. This is a retrospective review of consecutive patients at a single institution who underwent long thoracolumbar surgery with extension to the pelvis using this porous screw. Radiographic parameters of regional and global alignment were collected preoperatively and at the time of last follow-up. The incidence of intraoperative complications and need for revision were collected. The incidences of mechanical complications, including screw breakage, implant loosening/pullout, and screw cap dislocation at the time of last follow-up were also collected.

RESULTS
Ten patients with a mean age of 67 years were included, 6 of whom were male. Seven patients had a thoracolumbar construct with extension to the pelvis. Three patients had upper instrumented vertebrae at the proximal lumbar spine. Intraoperative breach was not encountered in any of the patients (0%). Postoperatively, 1 patient (10%) had screw breakage at the neck of the tulip of the modified iliac screw discovered at routine follow-up without clinical sequalae.

CONCLUSIONS
Use of self-harvesting porous S2AI screws incorporated into long thoracolumbar constructs was safe and feasible, demanding unique technical considerations. Long-term clinical and radiographic follow-up with a large patient cohort is necessary to determine their durability and efficacy to achieve SIJ arthrodesis and prevent SIJ dysfunction.
Resection of corticotroph microadenomas invading the medial wall of the cavernous sinus in two cases of a primary and recurrent case of Cushing’s disease

Published: July 2023

Emerging evidence from multiple highly specialized groups continues to support a role for resection of the medial wall of the cavernous sinus when it is invaded by functional pituitary adenomas, to offer durable biochemical remission. The authors present two cases of Cushing’s disease that underscore the power of this surgical technique in achieving remission in microadenomas that ectopically present in the cavernous sinus or have invaded the medial wall of the sinus. This video demonstrates key steps in the safe removal of the medial wall of the cavernous sinus and successful resection of tumor burden in the cavernous sinus for sustained postoperative remission.

Published: July 2023

A 54-year-old male with a history of diabetes mellitus type 2 for 12 years and hypertension was seen in the clinic due to poorly controlled diabetes. Inferior petrosal sinus sampling (IPSS) confirmed Cushing’s disease with primary adrenocorticotropic hormone (ACTH)–secreting pituitary adenoma on the right. However, 3T and subsequent 7T MRI showed no visible tumor. An endoscopic transsphenoidal approach was selected to explore the pituitary gland and resect the presumed microadenoma. Tumor was identified in the lateral recess along the right medial cavernous sinus wall and gross-total resection (GTR) was performed. The normal pituitary gland was preserved, and the patient went into remission.

Published: July 2023

OBJECTIVE
IDH-mutant grade 4 astrocytomas (AIDHmut/G4) are divided into primary de novo (pAIDHmut/G4) and secondary with a history of prior lower-grade gliomas (LGGs; sAIDHmut/G4). The mutational spectrum and DNA methylation patterns are homogeneous within de novo pAIDHmut/G4 and evolved sAIDHmut/G4, but the two groups have different diagnoses, management, and outcomes. This study sought to systematically compare the clinical, pathological, and survival characteristics between them.

METHODS
Of the 871 grade 4 astrocytomas with data for IDH mutation, 698 (80.1%) were primary and 173 (19.9%) were secondary. Of the 698 primary tumors, 103 (14.8%) were pAIDHmut/G4, and of the 173 secondary tumors, 108 (62.4%) were sAIDHmut/G4. Clinical, pathological, and survival features were compared between pAIDHmut/G4 and sAIDHmut/G4. Multivariate analyses were performed to identify prognostic factors.

RESULTS
Patients with sAIDHmut/G4 had significantly shorter median overall survival (OS; 11.8 vs 34.2 months, hazard ratio [HR] 2.69, 95% confidence interval [CI] 1.367–5.306, p = 0.004) and progression-free survival (PFS; 8.5 vs 24.3 months, HR 2.83, 95% CI 1.532–5.235, p = 0.001) than patients with pAIDHmut/G4. In patients with sAIDHmut/G4, resection status and chemotherapy were independent prognostic factors for OS and PFS; in patients with pAIDHmut/G4, LGG component, resection status, and O6-methylguanine DNA methyltransferase promoter methylation were independent prognostic factors. The therapeutic strategies of LGGs did not influence survival of patients with sAIDHmut/G4, but patients who had not received radiotherapy or chemotherapy when they were diagnosed with LGGs were found to benefit from radiotherapy or chemotherapy when they progressed to sAIDHmut/G4.

CONCLUSIONS
The different clinical characteristics, survival, and risk factors between sAIDHmut/G4 and pAIDHmut/G4 provide a reference to guide treatment decisions in AIDHmut/G4.

Published: July 2023

OBJECTIVE
Larger cerebral aneurysms are more likely to enlarge, but even small aneurysms can grow. The aim of this study was to investigate the hemodynamic characteristics regarding the growth of small aneurysms using computational fluid dynamics (CFD).

METHODS
The authors analyzed 185 patients with 215 unruptured cerebral aneurysms with a maximum diameter of 3–5 mm, registered in a multicenter prospective observational study of unruptured aneurysms (Systematic Multicenter Study of Unruptured Cerebral Aneurysms Based on Rheological Technique at Mie) from January 2013 to February 2022. Based on findings on repeated images, aneurysms were divided into a stable group (182 aneurysms) and a growth group (33 aneurysms). The authors developed the high shear concentration ratio (HSCR), in which high wall shear stress (HWSS) was defined as a value of 110% of the time-averaged wall shear stress of the dome. High shear area (HSA) was defined as the area with values above HWSS, and the ratio of the HSA to the surface area of the dome was defined as the HSA ratio (HSAR). They also created the flow concentration ratio (FCR) to measure the concentration of the inflow jet. Multivariate logistic regression analysis was performed to determine morphological variables and hemodynamic parameters that independently characterized the risk of growth.

RESULTS
The growth group had a significantly higher projection ratio (0.74 vs 0.67, p = 0.04) and volume-to–ostium area ratio (1.72 vs 1.44, p = 0.02). Regarding the hemodynamic parameters, the growth group had significantly higher HSCR (6.39 vs 4.98, p < 0.001), lower HSAR (0.28 vs 0.33, p < 0.001), and lower FCR (0.61 vs 0.67, p = 0.005). In multivariate analyses, higher HSCR was significantly associated with growth (OR 0.81, 95% CI 7.06 e−1 to 9.36 e−1; p = 0.004).

CONCLUSIONS
HSCR may be a useful hemodynamic parameter to predict the growth of small unruptured cerebral aneurysms.

Bishop in the History of the Church According to the Works of the Renovationist Metropolitan Alexander Vvedensky
Authors: Афанасьев М. В. 
Published: July 2023

Данная статья посвящена анализу взглядов Александра Введенского (1889–1946) — известного религиозного деятеля, одного из идеологов и лидеров обновленческого раскола. Вопрос о церковном устройстве и роли священной иерархии в жизни Церкви всегда имел особую актуальность. В ХХ в., после Октябрьской революции эта проблема стала ещё более значимой, особенно учитывая контекст деятельности обновленческого движения «Живой Церкви». Важным аспектом в данном случае являлось определение места епископа в церковном устройстве. На основании избранных мест из трудов автора и свидетельств его современников рассматривается отношение Александра Введенского к вопросу о том, какой должна быть роль епископа в жизни Церкви. Учитывая многогранность и определенный синкретизм во взглядах обновленческого митрополита, известного своей поддержкой Советской власти, стоит уделить особое внимание его видению церковного епископата.
This article is devoted to the analysis of the views of Alexander Vvedensky (1889–1946), a well-known religious figure, one of the ideologists and leaders of the Renovationist schism. The question of the church structure and the role of the sacred hierarchy in the life of the Church has always been of particular relevance. In the 20th century, after the October Revolution, this problem became even more significant, especially considering the context of the activities of the Living Church renovation movement. An important aspect in this case was the determination of the place of the bishop in the church structure. Based on selected passages from the author's works and the testimonies of his contemporaries, the attitude of Alexander Vvedensky to the question of what should be the role of a bishop in the life of the Church is considered. Given the versatility and certain syncretism in the views of the Renovationist Metropolitan, known for his support of the Soviet regime, it is worth paying special attention to his vision of the church episcopate.
