Split cord malformations (SCMs) are thought to be rare abnormalities representing 3.8-5% of all spinal cord anomalies. The prevalence is estimated to be 1 in 5499 live births (0.02%), with a slight female predominance (1.3:1). Although the estimates of prevalence vary, Type I SCM occurs more frequently than Type II SCM. In this paper, we are reporting the clinical presentation and imaging findings of multi-level SCM in a 27-year-old male. A literature review of the embryological background of SCM and pathological hypothesis for this entity is provided. A systematic review has been conducted to identify multi-level SCM cases reported in the literature, followed by proposing a new classification system to further our understanding and management of SCMs.

✓ The ventriculus terminalis is a small cavity inside the conus medullaris that is formed during the embryonic development. Previous reports regarding cystic lesion of the ventriculus terminalis (CLVT) in adults have detailed a broad and diversified distribution in terms of clinical symptoms, clinical evolution, neurological findings, and treatment. Therefore, nonstandardized management has led to unsatisfactory outcomes. Thus, the authors propose a new classification system in which the clinical presentation is taken into account to standardize the cases and facilitate the proper management of these lesions. Two more cases are described. The literature was reviewed, dividing the patients into 3 groups by clinical presentation as follows: CLVT Type I, patients with nonspecific neurological symptoms or nonspecific complaints; CLVT Type II, presence of focal neurological deficit; and CLVT Type III, presence of sphincter disturbances (bowel or bladder dysfunction). Two patients were classified as CLVT Type I, 3 as CLVT Type II, and 12 as CLVT Type III. In Type I, no improvement was observed in clinical evaluation after surgery, and stable symptoms were achieved with clinical management. In Type II, 2 patients had total improvement and 1 had subtotal improvement after surgery. Finally, in Type III, 92% of the patients improved postoperatively; among these 33% presented with total improvement. Only 1 case in this group was handled conservatively and no improvement was documented. This new classification is useful to group the patients into 3 clinical types to provide guidance as to the best management options. Treatment for the Type I lesion seems to be best conducted conservatively, whereas Types II and III seem to be best handled surgically.

Abstract BACKGROUND: The clinical significance of pathologies of the spinal dura is often unclear and their management controversial. OBJECTIVE: To classify spinal dural pathologies analogous to vascular aneurysms, present their symptoms and surgical results. METHODS: Among 1519 patients with spinal space-occupying lesions, 66 patients demonstrated dural pathologies. Neuroradiological and surgical features were reviewed and clinical data analyzed. RESULTS: Saccular dural diverticula (type I, n = 28) caused by defects of both dural layers, dissections between dural layers (type II, n = 29) due to defects of the inner layer, and dural ectasias (type III, n = 9) related to structural changes of the dura were distinguished. For all types, symptoms consisted of local pain followed by signs of radiculopathy or myelopathy, while one patient with dural ectasia presented a low-pressure syndrome and 10 patients with dural dissections additional spinal cord herniation. Type I and type II pathologies required occlusion of their dural defects via extradural (type I) or intradural (type II) approaches. For type III pathologies of the dural sac no surgery was recommended. Favorable results were obtained in all 14 patients with type I and 13 of 15 patients with type II pathologies undergoing surgery. CONCLUSION: The majority of dural pathologies involving root sleeves remain asymptomatic, while those of the dural sac commonly lead to pain and neurological symptoms. Type I and type II pathologies were treated with good long-term results occluding their dural defects, while ectasias of the dural sac (type III) were managed conservatively.

Introduction: Displaced supracondylar fracture in children is a challenging injury that may result in impaired functional and cosmetic outcome if not well-treated. Utilization of Closed Reduction and Percutaneus Pinning (CRPP) increased for this pathology, some authors believe ORIF results better anatomical reduction and lower rate of loss of reduction. Study aims to compare CRPP and ORIF for pediatric supracondylar humerus fracture. Method: Systematic review was conducted based on PRISMA guideline. Inclusion criteria were age <18 years old, comparing CRPP and ORIF for Supracondylar Humerus Fractures Gartland Type II, II.Studies of one surgical technique, Gartland type I, case reports were excluded. For meta-analysis, 6 studies were included and fixed effect model used to pool the result. In each study, mean difference (MD) with 95% confidence interval (CI) was calculated for dichotomous outcomes using Review Manager. Result: Total of 252 patients aged 0-15 years old were included. CRPP more often performed than ORIF. Satisfactory outcomes measured by Flynn’s criteria were achieved in 87.74% in CRPP and 86.73% in ORIF patient group, indicating significant difference (Heterogeneity, I2 = 23%; WMD, 1.26; 0.58 to 2.73; P =0.56). Conclusion: Current systematic review and meta-analysis suggest that for displaced supracondylar humerus fractures, ORIF offers a comparable functional and cosmetic outcome compared to CRPP.

AbstractInfrapatellar fat pad impingement represents a source of anterior knee pain that is often overlooked. Due to the scarcity of reports related to this disorder, we conducted a systematic review of the literature related to infrapatellar fat pad impingement in evaluating the following: (1) clinical presentation, (2) imaging, (3) management, and (4) clinical outcomes. A systematic review was conducted investigating all available primary literature related to the clinical presentation, imaging, management, and outcomes of infrapatellar fat pad impingement syndrome. A total of 15 studies (9 case reports, 1 case series, and 5 retrospective studies) comprising 167 patients met eligibility criteria for this review. Patients with infrapatellar fat pad impingement were found to most often present with anterior knee pain that worsened with activity, and was frequently associated with trauma. Anterior knee pain, tenderness to palpation over the patellar tendon, loss in terminal extension, and pain with direct pressure on the medial or lateral side of the patella with the knee extended was often found on examination. Although patients may have classic imaging findings on magnetic resonance imaging (localized edema of the infrapatellar fat pad, deep fluid-filled infrapatellar bursa, nonvisualization of clefts, fibrosis, and calcifications), not all patients had positive imaging findings, thus making infrapatellar fat pad impingement a clinical diagnosis. Treatment begins with nonoperative management, but in recalcitrant cases, patients can be surgically treated with arthroscopic fat pad resection. Most patients who undergo operative treatment report improvement or complete resolution of symptoms in terms of pain and range of motion, and are able to return to work. To the best of our knowledge, this is the first comprehensive review on infrapatellar fat pad impingement to better aid the orthopaedic surgeons in diagnosing, treating, and managing patient expectations for this often overlooked knee pathology.

Suprasellar Extension

Abstract BACKGROUND Rathke cleft cysts (RCCs), benign remnants of the Rathke pouch typically arising in the sella, sometimes have suprasellar extension. Purely suprasellar RCCs are rarely reported. OBJECTIVE To compare the presentations, surgical outcomes, and pathology of purely suprasellar RCCs and sellar-based RCCs. METHODS We retrospectively reviewed records, magnetic resonance images, laboratory results, and pathology of 151 RCC patients surgically managed at our institution from 1989 to 2009. The RCCs were classified as purely sellar (type I, n = 76), sellar with suprasellar extension (type II, n = 56), or purely suprasellar (type III, n = 19). RESULTS The RCCs with a suprasellar component (types II and III) more commonly presented with visual dysfunction (P &lt; .001). Complete cyst drainage occurred in 89%, 55%, and 38% of type I, II, and III RCCs, respectively (P &lt; .001). Vision improved in 100%, 55%, and 33% and headache improved in 74%, 64%, and 29% of type I, II, and III patients, respectively (P = .02). Temporary or permanent postoperative diabetes insipidus occurred in 5%, 16%, and 21% of type I, II, and III patients, respectively. (P &lt; .001). In a multivariate analysis, RCC type was the only factor predicting recurrence. Kaplan-Meier 3-year recurrence/progression rates were 0%, 16%, and 29% for type I, II, and III RCCs, respectively (P &lt; .001, type I vs II, type I vs III; P = .5 type II vs III). CONCLUSION The RCCs with a suprasellar component are neurosurgically challenging because of their proximity to the optic chiasm and infundibulum. Compared with sellar-based RCCs, RCCs with a suprasellar component more frequently present with visual dysfunction, are more difficult to completely eliminate, recur more frequently, and are associated with higher postoperative endocrine morbidity, and their preoperative visual dysfunction and headache less frequently improve with surgery. These factors must be considered during the treatment of RCCs with a suprasellar component.

Background and Purpose: The aim of this study was to compare the different subtypes of anterior choroidal artery (AChoA) aneurysm based on a new classification and to analyze the risk factors according to individual endovascular treatment (EVT).Methods: In the new classification, AChoA aneurysms are classified into independent type (I type) and dependent type (II type) based on the relationship between the AChoA and the aneurysm. II type aneurysms have three subtypes, IIa (neck), IIb (body), and IIc (direct). We retrospectively analyzed 52 cases of AChoA aneurysm treated in our center between 2015 to 2019. There were 13 (25.0%) I type aneurysms, 24 (46.2%) IIa aneurysms, 15 (28.8%) IIb aneurysms, and no IIc type; 28 cases had a subarachnoid hemorrhage. According to our preoperative EVT plan for the different subtypes: II type should achieve Raymond-Roy Occlusion Class 1 (RROC 1) where possible. To protect the AChoA, it is best to preserve the neck of the IIa type aneurysms (RROC 2), and RROC 3 is enough for IIb type.Results: Ten asymptomatic cases with minimal aneurysms were treated conservatively. Of the other cases, 42 were treated with individualized EVT (26 with a simple coil, 6 with balloon-assisted coiling, 7 with stent-assisted coiling, and 3 by flow diverter. Different subtypes had different RROC (Z = 14.026, P = 0.001). IIb type aneurysms (χ2 = 7.54, P = 0.023) were one of the factors related to temporary or permanent AChoA injury during surgery. Overall, two patients (IIa = 1, IIb = 1) developed contralateral hemiparesis.Conclusions: The new classification diagram clearly shows the features of all types of AChoA aneurysm and makes EVT planning more explicit. The II type (particularly IIb) was a potential risk factor for AChoA injury.

Abstract Background Current classifications emphasize the morphology of the coalition, however, subtalar joint facets involved should also be emphasized.Objective The objective of this study was to develop a new classification system based on the articular facets involved to cover all coalitions and guide operative planning.Methods Patients were diagnosed with talocalcaneal coalition using a CT scan, between January 2009 and February 2021. We classified the coalition into four main types according to the shape and nature of the coalition: I, inferiorly overgrown talus or superiorly overgrown calcaneus; II, both talus and calcaneus overgrew; III, coalition with an accessory ossicle; (I-III types are non-osseous coalition) IV, complete osseous coalition. Then each type was further divided into three subtypes according to the articular facets involved. A, the coalition involving the anterior facets; M, the coalition involving the middle facets, and P, the coalition involving the posterior facets.Results There were 106 patients (108 feet) included in this study. Overall, 8 feet (7.5%) were classified as type I, 75 feet (69.4%) as type II, 7 feet (6.5%) as type III, and 18 feet (16.7%) as type IV. Twenty-nine coalitions (26.9%) involved the posterior facets only (subtype-P), 74 coalitions (68.5%) involved both the middle and posterior facets (subtype-MP), and five coalitions (4.6%) simultaneously involved the anterior, middle, and posterior facets (subtype-AMP). Type II-MP coalition was the most common.Conclusion A new classification system of the talocalcaneal coalition to facilitate operative planning was developed.

Background Surgery is the gold standard in the management of inverted papilloma (IP); however, the approach and extent of the surgical procedure are still controversial. Moreover, there is still no universal staging system of IP to plan surgery and/or evaluate results. We performed a retrospective study. Methods A new classification depending on the origin of the lesion was used to plan surgery in 70 cases of IP. Conservative transnasal endoscopic excision was performed in lesions arising from the nasal septum and lateral nasal wall (type I IP, 42 cases) and radical transnasal endoscopic medial maxillectomy was performed in lesions arising from the maxillary sinus (type II IP, 28 cases). Results Excluding cases with a follow-up of <2 years, follow-up for periods ranging between 2 and 13.3 years with a median of 78 months showed recurrence in a single case of type I (3.2%) and 2 cases of type II (9.5%). Conclusion The new classification system, based on the origin of IP, is a simple tool for grading IP. It can be used to define cases suitable for conservative excision or radical medial maxillectomy. Both could be performed transnasally and endoscopically.
