Diastematomyelia is a rare congenital disorder characterized by the separation of the spinal cord by an osseocartilaginous or fibrous septum. While diastematomyelia has been reported to be more common in the thoracic and lumbar regions, the true incidence of cervical diastematomyelia is currently unknown. In this study, we conducted the most comprehensive systematic review to date of all other case reports of diastematomyelia to better characterize the incidence of cervical diastematomyelia and provide comprehensive statistics on the clinical characteristics of diastematomyelia generally. Ninety-one articles were included in our study, which comprised 252 males (27.9%) and 651 females (72.0%) (and one patient with unspecified gender). In 507 cases, the vertebral level of the diastematomyelia was described, and we recorded those levels as either cervical ( = 8, 1.6%), thoracic ( = 220, 43.4%), lumbar ( = 277, 54.6%), or sacral ( = 2, 0.4%). In 719 cases, the type of diastematomyelia was specified as either Type I ( = 482, 67.0%) or Type II ( = 237, 33.0%). Our study found that diastematomyelia has been reported in the cervical region in only 1.6% of cases, and we provide comprehensive data that this disorder occurs in female-to-male ratio of approximately 2.6:1 and Type I versus Type II diastematomyelia in an estimated ratio of 2:1.

Global Spine Journal Dec 2023A register-based retrospective series and a systematic review of literature.
STUDY DESIGN
A register-based retrospective series and a systematic review of literature.
OBJECTIVES
Tarlov cysts are meningeal cysts typically found in the sacral region. They have a dualistic nature ranging from an incidental finding to a symptomatic pathology. There are no established treatment protocols and predictors of operative outcome. Therefore, we aimed to study the outcome of surgical treatment for Tarlov cysts and to characterize patient-, and treatment-related factors predicting outcomes.
METHODS
A systematic review of previous literature was performed and a retrospective cohort of all patients operated on for Tarlov cysts at BLINDED between 1995 and 2020 was collected. Patient records were evaluated along with radiological images.
RESULTS
Ninety-seven consecutive patients were identified with follow-up data available for 96. Improvement of symptoms after surgery was observed in 76.0% of patients (excellent or good patient-reported outcome) and the complication rate was 17.5%. Sacral or lower back pain as a preoperative symptom was associated with improvement after surgery ( = .007), whereas previous lower back surgery was more common in patients who did not benefit from surgery ( = .034). No independent predictors of outcome were identified in a regression analysis.
CONCLUSIONS
This is the second-largest study on the treatment of Tarlov cysts ever published. Operative treatment in a selected patient population will likely produce improvement in the symptoms when balanced with the complication rate and profile of surgery. Preoperative lower back or sacral pain is a potential indicator for improvement after surgery.

Meta-Analysis Review
Several factors associated with poor outcome in patients with prenatally diagnosed sacrococcygeal teratoma (SCT) have been found. However, the prognostic accuracy of these factors has not been well established. Therefore, we aimed to systematically review the prognostic accuracy of factors associated with poor outcome in these patients. We queried Search Premier, COCHRANE Library, EMCARE, EMBASE, PubMed, ScienceDirect, and Web of Science databases to identify studies regarding patients with prenatally diagnosed SCT. Poor outcome was defined as termination of pregnancy (TOP), intrauterine fetal death (IUFD), or perinatal death. We estimated the odds ratio of factors associated with poor outcome. Eleven studies (447 patients) were included. Overall mortality, including TOP, was 34.9%. Factors associated with poor outcome in fetuses with prenatally diagnosed SCT were cardiomegaly, hypervascular tumor, solid tumor morphology, fetal hydrops, and placentomegaly. A tumor volume to fetal weight ratio (TFR) of >0.12 before a gestational age of 24 weeks is predictive of poor outcome. The prognostic accuracy of factors associated with poor outcome in fetuses prenatally diagnosed with SCT seems promising. Factors associated with cardiac failure such as cardiomegaly, hypervascular tumor, solid tumor morphology, fetal hydrops, placentomegaly, and TFR >0.12 were found to be predictive of poor outcome.

Meta-Analysis Review
OBJECTIVE
Carbon ion radiotherapy (C-ion RT) for chordomas has been gradually performed in several research centres. This study aimed to systematically review the results of clinical reports from these institutions and to evaluate the safety and efficacy of C-ion RT.
METHODS
In accordance with the PRISMA guidelines and set search strategies, we searched four databases for articles from their inception to February 11, 2023. These articles were screened, and data were extracted independently by two researchers. STATA 14.0 was used for statistical analysis of survival results.
RESULTS
A total of 942 related articles were retrieved, 11 of which were included. Regarding lesion location, 57% (n = 552) originated in the sacral region, 41% (n = 398) in the skull base, and 2% (n = 19) in the spine (upper cervical). The local control (LC) rates at 1, 2, 3, 5, 9, and 10 years in these studies were 96%, 93%, 83%, 76%, 71%, and 54%, respectively. The overall survival (OS) rates at 1, 2, 3, 5, 9, and 10 years in these studies were 99%, 100%, 93%, 85%, 76%, and 69%, respectively. Acute and late toxicities were acceptable, acute toxicities were mainly grade 1 to grade 2 and late toxicities were mainly grade 1 to grade 3.
CONCLUSION
C-ion RT has attractive clinical application prospects and is an important local treatment strategy for chordomas. Encouraging results were observed in terms of LC and OS. Meanwhile, the acute and late toxicities were acceptable. PROSPERO registration number: CRD42023398792.

Review
BACKGROUND
Spinal manipulation (SM) is a recommended and effective treatment for musculoskeletal disorders. Biomechanical (kinetic) parameters (e.g. preload/peak force, rate of force application and thrust duration) can be measured during SM, quantifying the intervention. Understanding these force-time characteristics is the first step towards identifying possible active ingredient/s responsible for the clinical effectiveness of SM. Few studies have quantified SM force-time characteristics and with considerable heterogeneity evident, interpretation of findings is difficult. The aim of this study was to synthesise the literature describing force-time characteristics of manual SM.
METHODS
This scoping literature review is reported following the Preferred Reporting Items for Scoping Reviews (PRISMA-ScR) statement. Databases were searched from inception to October 2022: MEDLINE (Ovid), Embase, CINAHL, ICL, PEDro and Cochrane Library. The following search terms and their derivatives were adapted for each platform: spine, spinal, manipulation, mobilization or mobilisation, musculoskeletal, chiropractic, osteopathy, physiotherapy, naprapathy, force, motor skill, biomechanics, dosage, dose-response, education, performance, psychomotor, back, neck, spine, thoracic, lumbar, pelvic, cervical and sacral. Data were extracted and reported descriptively for the following domains: general study characteristics, number of and characteristics of individuals who delivered/received SM, region treated, equipment used and force-time characteristics of SM.
RESULTS
Of 7,607 records identified, 66 (0.9%) fulfilled the eligibility criteria and were included in the analysis. Of these, SM was delivered to the cervical spine in 12 (18.2%), the thoracic spine in 40 (60.6%) and the lumbopelvic spine in 19 (28.8%) studies. In 6 (9.1%) studies, the spinal region was not specified. For SM applied to all spinal regions, force-time characteristics were: preload force (range: 0-671N); peak force (17-1213N); rate of force application (202-8700N/s); time to peak thrust force (12-938ms); and thrust duration (36-2876ms).
CONCLUSIONS
Considerable variability in the reported kinetic force-time characteristics of SM exists. Some of this variability is likely due to differences in SM delivery (e.g. different clinicians) and the measurement equipment used to quantify force-time characteristics. However, improved reporting in certain key areas could facilitate more sophisticated syntheses of force-time characteristics data in the future. Such syntheses could provide the foundation upon which dose-response estimates regarding the clinical effectiveness of SM are made.

The Journal of Craniofacial Surgery Oct 2023The purpose of this article was to appraise the various methods of reconstruction for meningomyelocele (MMC) defects.
PURPOSE
The purpose of this article was to appraise the various methods of reconstruction for meningomyelocele (MMC) defects.
METHODS
A systematic review of the literature was performed to evaluate all reconstructions for MMC. The method of reconstruction was categorized by: primary closure with and without fascial flaps, random pattern flaps, VY advancement flaps (VY), perforator flaps, and myocutaneous flaps. Perforator flaps were subsequently subcategorized based on the type of flap.
RESULTS
Upon systematic review, 567 articles were screened with 104 articles assessed for eligibility. Twenty-nine articles were further reviewed and included for qualitative synthesis. Two hundred seventy patients underwent MMC repair. The lowest rates of major wound complications (MWC) were associated with myocutaneous and random pattern flaps. A majority of MWC was in the lumbrosacral/sacral region (87.5% of MWC). In this region, random patterns and perforator flaps demonstrated the lowest rate of MWC (4.5, 8.1%).
CONCLUSIONS
Plastic surgery consultation should be strongly considered for MMC with defects in the lumbosacral/sacral region. Perforator flaps are excellent options for the reconstruction of these defects.

Journal of Tissue Viability May 2023To develop a systematic review on the prevalence and the incidence of pressure ulcers/injuries in adult patients in hospital emergency services. (Review)
Review
AIM
To develop a systematic review on the prevalence and the incidence of pressure ulcers/injuries in adult patients in hospital emergency services.
MATERIALS AND METHODS
Systematic review of prevalence and incidence studies developed according to the Preferred Reporting Items Form Systematic Review and Meta-Analysis Protocols and the Joanna Briggs Institute methodology. The inclusion criteria were based on the CoCoPop mnemonic. The main variables of interest were the "prevalence" and/or the "incidence" of "pressure ulcers/injuries" (Condition) reported in studies developed in hospital emergency services (Context) with adult participants (Population). The Systematic Review Protocol was registered in PROSPERO (CDR42021252906).
RESULTS
The pressure ulcer/injury (point) prevalence ranged from 5.2% (at admission) to 12.3% (at discharge) and the pressure ulcer/injury incidence ranged from 4.5% to 78.4%. Most of the pressure ulcers/injuries documented were category/stage I. The most problematic anatomical locations were the sacrococcygeal region and the heels. The preventive measures should be implemented as soon as possible and are important in patients older than 75 years, with multiple comorbidities, high C-Reative Protein levels, cervical spine immobilization, presented to hospital emergency service by ambulance or with hypotension at the time of admission.
CONCLUSIONS
The prevalence and incidence of pressure ulcers/injuries in hospital emergency services remains an understudied topic which could limit the generalization of our data. This systematic review highlighted that the management of pressure ulcers/injuries is a real and current challenge in hospital emergency services. It is important to identify the patients at (higher) risk to establish an (earlier) preventive care plan according to patients and emergency services' characteristics.

Meta-Analysis
BACKGROUND
Pilonidal sinus is a common disease in the sacrococcygeal region. Although many treatments have been described in recent years, the recurrence of each method remains high. Surgeons did not reach a consensus on the preferred approach for pilonidal sinus. We carried out a meta-analysis of controlled clinical trials comparing the outcomes of endoscopic treatment versus conventional treatment for pilonidal sinus disease in this study.
METHODS
We performed a systematic literature search, and we used electronic databases such as PubMed/Medline, Embase, and the Cochrane library to search for the relevant literature comparing endoscopic management to other conventional treatments for pilonidal sinus disease. The primary outcome parameters were operative time, recurrence, postoperative complications and pain, and total healing time.
RESULTS
Six studies were included in the review. Endoscopic pilonidal sinus treatment had a lower overall complication rate than the conventional surgery group (risk ratio = 0.33 [0.19-0.58], P = .0001) and lower pain score with a weighted mean difference of -2.44 (95% confidence interval: (-3.96) to (-0.92), I2 = 99%, P = .002). There was no significant difference in recurrence (risk ratio = 0.75, 95% confidence interval [0.30-1.90],P = .55). Compared to the excision followed by the primary closure technique, the operation time, time to complete wound healing, and satisfaction were similar.
CONCLUSIONS
Endoscopic pilonidal sinus treatment is a unique and potential method of sacrococcygeal pilonidal disease treatment. The foremost benefits of this technique are mild postoperative pain, lower complications rate, and return to routine for a shorter time. However, due to the limited number of articles, we need to conduct more rigorous large-sample prospective randomized controlled trials to clarify the efficiency of endoscopic treatment for pilonidal cysts.

Review
Sacrococcygeal teratoma (SCT) is a rare neoplasm affecting 1:35,000 newborns. Long-term follow-up from small observational studies report impaired bladder/bowel function. This current study comprehensively analyses all published studies to better define true long-term functional sequelae. Medline/Embase databases were searched with PRISMA guidelines. Final analysis yielded 37 studies involving 1116 patients (854 female; 77%). Individual datasets were available in 14 studies (222 patients). According to Altman classification - 298/845 (35%) were Type I, 252/845 (30%) Type II, 133/845 (16%) Type III, and 128/845 (15%) Type IV tumours. Most neoplasms were benign (640/858; 75%), 77/858 (9%) immature and 141/858 (16%) malignant. Abnormal bladder function was reported in 7/39 (18%) Altman Type I, 23/61 (37.7%) Type II, 11/34 (32.4%) Type III, and 15/25 (60%) Type IV cases (p = 0.007). Adverse urological outcomes were notably common in immature/malignant neoplasms vs benign tumours and in patients requiring reoperation(s); p = 0.002 and p = 0.01. Bowel dysfunction was evident in 19% index cases and constipation in 26% with no significant association(s) with tumour characteristics. Higher Altman stage, unfavourable tumour biology and reoperation are associated with poor functional outcome(s). Multidisciplinary management from primary diagnosis of SCT is crucially important for all patients to best optimise functional outcomes across surgical specialities.

Spinal filum terminale pial arteriovenous fistulas (FT PAVFs) are uncommon. Most FT PAVFs are located in the lumbar region; far fewer are located in the sacral region. Due to the rarity of sacral FT PAVFs, the precise surgical dissection and removal of these lesions are challenging. Here, we report an FT PAVF in the sacral region. The patient was a 45-year-old male who suffered from progressive weakness and numbness of the bilateral lower limbs; his symptoms gradually worsened. Digital subtraction angiography (DSA) showed an AVF at the sacral canal at the S3-4 level. Microsurgical treatment with intraoperative DSA was performed, and the FT PAVF was resected. After the operation, the patient gradually recovered. Follow-up magnetic resonance imaging revealed a recession in the dilation of the spinal cord venous plexuses. A literature review was also performed, and a total of 14 FT PAVFs of the sacral region were identified. The patients identified in the literature review had an average age of 58.9 ± 12.9 years, and 92.9% of the patients were male. Spinal cord edema was present in 85.7% of the FT PAVF patients. Regarding treatment, 64.3% of the FT PAVF patients underwent microsurgical resection, 28.6% patients underwent endovascular treatment, and 7.1% patients underwent a hybrid operation; good outcomes were achieved with all three methods. Therefore, FT PAVF of the sacral region is a unique lesion whose angioarchitecture needs to be identified carefully; prompt treatment is necessary, and microsurgery can yield good outcomes.
