OBJECTIVEThe health care costs for instrumented spine surgery have increased dramatically in the last few decades. The authors present a novel noninstrumented surgical approach for patients with isthmic spondylolisthesis, with clinical and radiographic results.METHODSCharts of patients who underwent this technique were reviewed. The procedure consisted of nerve root decompression by reconstruction of the intervertebral foramen. This was achieved by removal of the pedicle followed by noninstrumented posterolateral fusion in which autologous bone graft from the right iliac crest was used. Outcomes regarding radicular complaints, bony fusion, progression of the slip, and complications were evaluated using patient history and radiographs obtained at follow-up intervals of 3–18 months after surgery.RESULTSA total of 58 patients with a mean age of 47 years were treated with this method. Partial removal of the pedicle was performed in 93.1% of the cases, whereas in 6.9% of the cases the entire pedicle was removed. The mean duration of surgery was 216.5 ± 54.5 minutes (range 91–340 minutes). The mean (± SD) duration of hospitalization was 10.1 ± 2.9 days (range 5–18 days).After 3 months of follow-up, 86% of the patients reported no leg pain, and this dropped to 81% at last follow-up. Radiographic follow-up showed bony fusion in 87.7% of the patients. At 1 year, 5 patients showed progression of the slip, which in 1 patient prompted a second operation within 1 year. No major complications occurred.CONCLUSIONSTreatment of isthmic spondylolisthesis by reconstruction of the intervertebral neuroforamen and posterolateral fusion in situ is a safe procedure and has comparable results with the existing techniques. Cost-effectiveness research comparing this technique to conventional instrumented fusion techniques is necessary to evaluate the merits for both patients and society.

Background:Pediatric to adult rheumatology transition can be a challenge for both the patient and the clinician, especially in rheumatology as it includes chronic diseases with close follow-up.Objectives:The objective of this study is to understand our tertiary rheumatology center patient demographic transitioning from pediatric to adult rheumatology in order to design prospective studies enhancing the evidence of transition recommendations.Methods:Patients included in this study are regularly followed-up in our adult rheumatology clinic and were regularly followed up in our pediatric rheumatology clinic in the past. They were all diagnosed with a rheumatologic condition receiving treatment. The patient files were assessed to have a better understanding of their demographic, disease and treatment information.Results:Our cohort includes 347 patients diagnosed with a variety of conditions that are Familial Mediterranean Fever (FMF) (n=216), Juvenile Idiopathic Arthritis (JIA) (n=56), Juvenile Spondyloarthritis (jSPA) (n=39), Systemic Lupus Erythematosus (SLE) (n=20), Behçet’s Disease (n=7) and the rest of the rheumatologic conditions with less than 5 patients each. The mean age of the patients during transition, mean age of diagnosis, and follow-up duration are 21.34±1.7, 10.4±4.18, and 10.82±4.4 in respective order. The treatment regimens the patients received are summarized in Table 1.Table 1.Current Treatment Information of the PatientsCurrent Treatment InformationDMARD26Colchicine23Adalimumab21Etanercept10NSAID4Tocilizumab3Cyclophosphamide3Rituximab2Prednisolone7Mycophenolate Mofetil1Canakinumab1Seven patients had FMF related attacks. In addition to attacks, one FMF patient had bilateral ankle pain and one patient had leg pain. One patient out of three diagnosed with Takayasu’s disease was still symptomatic. One patient had uveitis-related symptoms. One patient diagnosed with SLE had skin dryness. Furthermore, there were patients with sequelae formation. One patient diagnosed with oligoarticular JIA (oJIA) had bilateral hip sequela with the additional left hip prosthesis. One oJIA patient had micrognathia, and one had left knee sequela. One pJIA patient had small joint sequelae. One sJIA patient had bilateral hip sequelae. One jSPA patient had enthesopathy. One FMF patient had proteinuria due to amyloidosis formation. Another FMF patient had hip surgery due to sequela.Conclusion:Our center had patients with a variety of conditions with different natures of diseases. EULAR recommends the transition process to start no later than 14 years of age; however, this process started at the mean age of 21 in our patients. In most of these patients, especially the ones diagnosed with FMF, the control of disease activity was maintained. The transition of these different clinical entities might require certain amendments to the standard of care. For future references, we will be able to understand more about the adulthood prognosis of these clinical entities.Disclosure of Interests:None declared

OBJECTIVE Historically, bilateral frontoorbital advancement (FOA) has been the keystone for treatment of turribrachycephaly caused by bilateral coronal synostosis. Early endoscopic suturectomy has become a popular technique for treatment of single-suture synostosis, with acceptable results and minimal perioperative morbidity. Boston Children's Hospital has adopted this method of treating early-presenting cases of bilateral coronal synostosis. METHODS A retrospective review of patients with bilateral coronal craniosynostosis who were treated with endoscopic suturectomy between 2005 and 2012 was completed. Patients were operated on between 1 and 4 months of age. Hospital records were reviewed for perioperative morbidity, length of stay, head circumference and cephalic indices, and the need for further surgery. RESULTS Eighteen patients were identified, 8 males and 10 females, with a mean age at surgery of 2.6 months (range 1–4 months). Nine patients had syndromic craniosynostosis. The mean duration of surgery was 73.3 minutes (range 50–93 minutes). The mean blood loss was 40 ml (range 20–100 ml), and 2 patients needed a blood transfusion. The mean duration of hospital stay was 1.2 days (range 1–2 days). There was 1 major complication in the form of a CSF leak. The mean follow-up was 37 months (range 6–102 months). Eleven percent of nonsyndromic patients required a subsequent FOA; 55.6% of syndromic patients underwent FOA. The head circumference percentiles and cephalic indices improved significantly. CONCLUSIONS Early endoscopic suturectomy successfully treats the majority of patients with bilateral coronal synostosis, and affords a short procedure time, a brief hospital stay, and an expedited recovery. Close follow-up is needed to detect patients who will require a secondary FOA due to progressive suture fusion or resynostosis of the released coronal sutures.

Object. Brachycephaly is a characteristic feature of Apert syndrome. Traditional techniques of cranioplasty often fail to produce an acceptable morphological outcome in patients with this condition. In 1996 a new surgical procedure called “dynamic cranioplasty for brachycephaly” (DCB) was reported. The purpose of the present study was to analyze perioperative data and morphological long-term results in patients with the cranial vault deformity of Apert syndrome who were treated with DCB. Methods. Twelve patients have undergone surgery performed using this technique since its introduction in 1991 (mean duration of follow-up review 60.2 months). Eleven patients had bicoronal synostosis and one had a combined bicoronal—bilambdoid synostosis. Perioperative data and long-term evolution of skull shape visualized on serial cephalometric radiographs were analyzed and compared with normative data. Changes in mean skull proportions were evaluated using a two-tailed paired-samples t-test, with differences being considered significant for probability values less than 0.01. The mean operative blood transfusion was 136% of estimated red cell mass (ERCM) and the mean postoperative transfusion was 48% of ERCM. The mean operative time was 218 minutes. The duration of stay in the intensive care unit averaged 1.7 days and the mean hospital stay was 11.8 days. There were no incidences of mortality and few complications. An improvement in skull shape was achieved in all cases, with a change in the mean cephalic index from a preoperative value of 90 to a postoperative value of 78 (p = 0.000254). Conclusions. Dynamic cranioplasty for brachycephaly is a safe procedure, yielding high-quality morphological results in the treatment of brachycephaly in patients with Apert syndrome.

Study Design: Prospective observational study.Purpose: To assess the safety, efficacy, and benefits of computed tomography (CT)-guided C1 fracture fixation.Overview of Literature: The surgical management of unstable C1 injuries by occipitocervical and atlantoaxial (AA) fusion compromises motion and function. Monosegmental C1 osteosynthesis negates these drawbacks and provides excellent functional outcomes.Methods: The patients were positioned in a prone position, and cranial traction was applied using Mayfield tongs to restore the C0–C2 height and obtain a reduction in the displaced fracture fragments. An intraoperative, CT-based navigation system was used to enable the optimal placement of C1 screws. A transverse rod was then placed connecting the two screws, and controlled compression was applied across the fixation. The patients were prospectively evaluated in terms of their clinical, functional, and radiological outcomes, with a minimal follow-up of 2 years.Results: A total of 10 screws were placed in five patients, with a mean follow-up of 40.8 months. The mean duration of surgery was 77±13.96 minutes, and the average blood loss was 84.4±8.04 mL. The mean combined lateral mass dislocation at presentation was 14.6±1.34 mm and following surgery, it was 5.2±1.64 mm, with a correction of 9.4±2.3 mm (<i>p</i> <0.001). The follow-up CT showed excellent placement of screws and sound healing. There were no complications and instances of AA instability. The clinical range of movement at 2 years in degrees was as follows: rotation to the right (73.6°±9.09°), rotation to the left (71.6°±5.59°), flexion (35.4°±4.5°), extension (43.8°±8.19°), and lateral bending on the right (28.4°±10.45°) and left (24.8°±11.77°). Significant improvement was observed in the functional Neck Disability Index from 78±4.4 to 1.6±1.6. All patients returned to their occupation within 3 months.Conclusions: Successful C1 reduction and fixation allows a motion-preserving option in unstable atlas fractures. CT navigation permits accurate and adequate monosegmental fixation with excellent clinical and radiological outcomes, and all patients in this study returned to their preoperative functional status.

OBJECTIVE Lateral lumbar interbody fusion (LLIF) via a transpsoas approach is a workhorse minimally invasive approach for lumbar arthrodesis that is often combined with posterior pedicle screw fixation. There has been increasing interest in performing single-position surgery, allowing access to the anterolateral and posterior spine without requiring patient repositioning. The feasibility of the transpsoas approach in patients in the prone position has been reported. Herein, the authors present a consecutive case series of all patients who underwent single-position prone transpsoas LLIF performed by an individual surgeon since adopting this approach. METHODS A retrospective review was performed of a consecutive case series of adult patients (≥ 18 years old) who underwent single-position prone LLIF for any indication between October 2019 and November 2020. Pertinent operative details (levels, cage use, surgery duration, estimated blood loss, complications) and 3-month clinical outcomes were recorded. Intraoperative and 3-month postoperative radiographs were reviewed to assess for interbody subsidence. RESULTS Twenty-eight of 29 patients (97%) underwent successful treatment with the prone lateral approach over the study interval; the approach was aborted in 1 patient, whose data were excluded. The mean (SD) age of patients was 67.9 (9.3) years; 75% (21) were women. Thirty-nine levels were treated: 18 patients (64%) had single-level fusion, 9 (32%) had 2-level fusion, and 1 (4%) had 3-level fusion. The most commonly treated levels were L3–4 (n = 15), L2–3 (n = 12), and L4–5 (n = 11). L1–2 was fused in 1 patient. The mean operative time was 286.5 (100.6) minutes, and the mean retractor time was 29.2 (13.5) minutes per level. The mean fluoroscopy duration was 215.5 (99.6) seconds, and the mean intraoperative radiation dose was 170.1 (94.8) mGy. Intraoperative subsidence was noted in 1 patient (4% of patients, 3% of levels). Intraoperative lateral access complications occurred in 11% of patients (1 cage repositioning, 2 inadvertent ruptures of anterior longitudinal ligament). Subsidence occurred in 5 of 22 patients (23%) with radiographic follow-up, affecting 6 of 33 levels (18%). Postoperative functional testing (Oswestry Disability Index, SF-36, visual analog scale–back and leg pain) identified significant improvement. CONCLUSIONS This single-surgeon consecutive case series demonstrates that this novel technique is well tolerated and has acceptable clinical and radiographic outcomes. Larger patient series with longer follow-up are needed to further elucidate the safety profile and long-term outcomes of single-position prone LLIF.

Abstract Background Femoral head fractures are uncommon injuries. Open reduction and internal fixation (ORIF) of femoral head fracture is the preferred treatment for most patients. There are several surgical approaches and treatments for this difficult fracture. However, the optimal surgical approach for the treatment of femoral head fracture remains controversial. Meanwhile, the operation is difficult and the complications are numerous. We prospectively reviewed patients with femoral head fractures managed surgically through the 3D printing-based Ganz approach to define a better approach with the least morbidity. Patients and methods Between 2012 and 2017, a total of 17 patients were included in this study. An exact 1:1 3D printing model of the injured hip side was fabricated for each patient and simulated surgery was finished preoperative. The surgical approach was performed as described by Ganz. Functional assessment was performed using the modified Merle d’Aubigne scores. The reduction of the fracture was evaluated according to Matta’s criteria. The incidence of complications, such as heterotopic ossification (HO) and avascular necrosis (AVN), and the need for additional surgery were also documented. Results Twelve of 17 patients (four females and eight males) were available for 2 years follow-up. The mean follow-up was 35 months (25–48 months). Average age for the 12 patients was 39.9 ± 12.2 years. According to the Pipkin classification, four patients were type I fracture, three patients were type II fracture, and five patients were type IV fracture. The mean operative time was 124.2 ± 22.1 min, and the estimated blood loss was 437.5 ± 113.1 ml. According to Merle d’ Aubigne scores, excellent results were achieved in six of the 12 patients; four good and two poor results occurred in the rest of the patients. On the radiograph evaluation, fracture reduction was defined as anatomical in eight patients, and imperfect in four. Most patients had good outcomes and satisfactory hip function at last follow-up. Almost all great trochanteric osteectomy healed uneventfully. One patient developed symptomatic AVN of the femoral head and underwent THA at 3 years. After THA, she regained a good hip function with the ability to return to work and almost no reduction in sports activities. Heterotopic ossification was found in four cases (type I-1, type II-2, and type III-1). Conclusions The 3D printing-based Ganz approach provides a safe and reliable approach and satisfactory results of treatment in femoral head fractures. Using 3D printed model for the fracture of the femoral head, the fracture can be viewed in every direction to provide an accurate description of fracture characteristics, which contributes to make a reasonable surgical plan for patients. In addition, the 3D printing-based Ganz approach can obtain excellent surgical exposure and protection of the femoral head blood supply, reduce the operation time and intraoperative blood loss, make the precise osteotomy, anatomically fix the intra-articular fragments, and effectively reduce postoperative complications.

Object Outside of the patient population with achondroplasia, neurogenic claudication is rare in the pediatric age group. Neurogenic claudication associated with posterior vertebral rim fracture is even more uncommon but nonetheless causes pain and disability in affected children and adolescents. The purpose of this study was to describe the surgical results of 3 adolescents presenting with neurogenic claudication and posterior vertebral rim fracture when treated with laminectomy alone. Methods The medical and operative records of the 3 pediatric patients were retrospectively reviewed. Presenting signs and symptoms and CT findings, such as the interpedicular distances between T-12 and L-5, were obtained. Perioperative results were assessed, including operative time, blood loss, length of hospital stay, and complications. Findings at latest follow-up were also recorded, including a patient satisfaction survey. Results The 3 patients (1 girl and 2 boys) had a mean age of 14.7 years (range 14–15 years) and underwent follow-up for a mean of 11.3 months (range 5–18 months). Notable preoperative signs and symptoms included back pain (all patients), leg pain (all patients), leg numbness (1 patient), and leg weakness (1 patient). No patient presented with bowel and/or bladder dysfunction. The mean blood loss during laminectomy was 123 ml (range 20–300 ml), and the mean length of hospital stay was 4.3 days (range 3–6 days). On average, decompression was performed at 2.2 levels (range 2–2.5 levels). All 3 patients reported at most recent follow-up that they were “satisfied” with the surgery. There was 1 complication of instability from an iatrogenic pars fracture, which required reoperation and posterior instrumented fusion. Conclusions To the best of the authors' knowledge, this report represents the first surgical series of pediatric neurogenic claudication associated with posterior vertebral rim fractures. Pediatric neurosurgeons may infrequently encounter neurogenic claudication associated with a posterior vertebral rim fracture in children. To treat children with neurogenic claudication associated with posterior vertebral rim fractures, a simple laminectomy may be a safe and efficacious alternative to discectomy and removal of fracture fragments.

ABSTRACT Objective: To analyze the degeneration of the adjacent disc after arthrodesis due to thoracolumbar fractures. Methods: Eighty-three patients who underwent posterolateral arthrodesis in thoracolumbar levels had their x-rays analyzed for degeneration of adjacent discs to the arthrodesis. The disc spaces were classified by the UCLA scale. Results: Of the 83 patients evaluated, 66 were males (79%) and 18 females (21%), with a mean age of 35.5 years. The mean follow-up period was 40 months. As the fractures 75% were between T12 and L2 (p<0.001), being of the A3 type in 65% of the cases (p<0.001). The most common mechanism of injury, accounting for 50% of the cases (p<0.001), was fall from height. Only 6% of the superior discs and 12% of the inferior ones showed some degree of degeneration. No patient underwent a new surgical approach. Conclusion: The incidence of degeneration on adjacent disc in patients after arthrodesis resulting from fractures ranged from 6% to 12% with an average follow-up of 40 months.

✓ The purpose of this study was to determine the efficacy and feasibility of posterolateral percutaneous endoscopic lumbar foraminotomy (PELF) for foraminal or lateral exit zone stenosis of the L5—S1 level in the awake patient. Twelve consecutive patients with L5—S1 foraminal stenosis and associated leg pain underwent PELF between May 2001 and July 2002. Under fluoroscopic guidance, posterolateral endoscopic foraminal decompression was performed using a bone reamer, endoscopic forceps, and a laser. Using this new technique, the authors removed part of the hypertrophied superior facet, thickened ligamentum flavum, and protruded disc compressing the exiting (L-5) nerve root. Clinical outcome was measured using the Macnab criteria. The mean follow-up period was 12.9 months. All the patients were discharged within 24 hours. Satisfactory (excellent or good) results were demonstrated in 10 patients. There was no complication. The PELF procedure provides a simple alternative for treating lumbar foraminal or lateral exit zone stenosis in selected cases. The authors found that the posterolateral endoscopic approach to the L5—S1 foramen was usually possible and that using a bone reamer to undercut the superior facet was effective.

Abstract OBJECTIVE To analyze pre- and postoperative x-rays of sagittal spines and to review the surgical results of 21 patients with lumbar degenerative kyphosis whose spines were sagittally well compensated by compensatory mechanisms but who continued to suffer from intractable back pain METHODS We performed a retrospective review of 21 patients treated with combined anterior and posterior spinal arthrodesis. Inclusion criteria were: lumbar degenerative kyphosis patients with intractable back pain and whose spines were sagittally well compensated by a compensatory mechanism, defined as a C7 plumb line to the posterior aspect of the L5–S1 disc of less than 5 cm. Outcome variables included: radiographic measures of preoperative, postoperative, and follow-up films; clinical assessment using the mean Numeric Rating Scale, Oswestry Disability Index, and Patient Satisfaction Index; and a review of postoperative complications. RESULTS All patients were female (mean age, 64.5 years; age range, 50–74 years). The mean preoperative sagittal imbalance was 19.5 (± 17.6) mm, which improved to −15.8 (± 22.2) mm after surgery. Mean lumbar lordosis was 13.2 degrees (± 15.3) before surgery and increased to 38.1 degrees (± 14.4) at follow-up (P &lt; 0.0001). Mean thoracic kyphosis was 5.5 degrees (± 10.2) before surgery and increased to 18.9 degrees (± 12.4) at follow-up (P &lt; 0.0001). Mean sacral slopes were 12.9 degrees (± 11.1) before surgery and increased to 26.3 degrees (± 9.6) at follow-up (P &lt; 0.0001). The mean Numeric Rating Scale score improved from 7.8 (back pain) and 8.1 (leg pain) before surgery to 3.0 (back pain) and 2.6 (leg pain) after surgery (P &lt; 0.0001). The mean Oswestry Disability Index scores improved from 56.2% before surgery to 36.7% after surgery (P &lt; 0.0001). In 18 (85.5%) of 21 patients, satisfactory outcomes were demonstrated by the time of the last follow-up assessment. CONCLUSION This study shows that even lumbar degenerative kyphosis patients with spines that are sagittally well compensated by compensatory mechanisms may suffer from intractable back pain and that these patients can be treated effectively by the restoration of lumbar lordosis.
