A sound operative plan based on solid understanding of the pathology and biomechanics is the most important part of cervical deformity correction. Many different surgical options exist for operative management of cervical spine deformities. However, selecting the correct approach that ensures the optimal clinical outcome can be challenging and often controversial. In Part 2 of this three-part review series, we discuss the pre-operative planning, management algorithm, and anterior surgical techniques for cervical deformity correction...

BACKGROUND AND IMPORTANCE: In contrast to cranial interventions, neuronavigation in spinal surgery is used in few applications, not tapping into its full technological potential. We have developed a method to preoperatively create virtual resection planes and volumes for spinal osteotomies and export 3-D operation plans to a navigation system controlling intraoperative visualization using a surgical microscope's head-up display. The method was developed using a Sawbone ® model of the lumbar spine, demonstrating feasibility with high precision...

BACKGROUND: The growing rod remains an effective option in the treatment of early-onset scoliosis, and has previously been likened to an internal brace. While details of growing-rod treatment have been largely agreed on, the appropriate end point remains a matter of controversy. A decision was made in 2004, at the beginning of growing-rod treatment at our institution, to remove longitudinal instrumentation when the period of lengthening concluded and, similar to discontinuing a brace, leave the spine free...

Objectives Risk factors portending poor outcome following elective spine deformity fusion remain in need of characterization and stratification in the elderly population. Methods Cases aged ≥60 years who underwent elective posterior or anterior-posterior ('combined') fusion were extracted from the American College of Surgeons National Surgical Quality Improvement Program years 2007-2013 and analyzed by surgical cohort (posterior vs. combined). The 30-day outcomes included operation time, hospital length of stay (HLOS), perioperative complications, and discharge destination...

The purpose of the current work was to quantify the influence of posture-mediated skin deformation on trunk dorsum tactile perceptual sensitivity. Twelve young and healthy individuals were assessed while adopting three different spine postures (extension, neutral and flexion). Tactile sensitivity threshold tests (T10 and L4 vertebral levels) included measures of touch sensitivity, spatial acuity and stretch sensitivity. The results demonstrate that tactile sensitivity can differ due to changes in body posture...

OBJECTIVE: To analyze the impact of a physiotherapy protocol in maximum inspiratory and expiratory pressure in patients with adolescent idiopathic scoliosis (AIS) by manovacuometry. AIS may change the respiratory dynamics and the performance of inspiratory and expiratory muscles, affecting ventilatory capacity. METHODS: Patients with AIS aged 10 to 20 years old were randomly assigned to receive an aerobic exercise-training program or no treatment. They were evaluated for respiratory muscle strength before and after the treatment period by means of manovacuometry, thorax and spine radiographs...

INTRODUCTION: Kyphosis is a frequent problem in children with spina bifida, and this deformity may cause different complications as respiratory insufficiency, bowel dysfunction, and skin ulcers. CASE REPORT: We report on a 13-year-old myelomeningocele male with a lumbar kyphoscoliosis associated to a septic skin ulceration that resulted in an acute sepsis. An X-ray revealed a kyphosis of 110° and a scoliosis of 25° between T9 and L5. The wound and blood cultures showed Staphylococcus aureus colonization, and an appropriate antibiotic therapy was started...

Background and purpose - Routine outcome measurement has been shown to improve performance in several fields of healthcare. National spine surgery registries have been initiated in 5 Nordic countries. However, there is no agreement on which outcomes are essential to measure for adolescent and young adult patients with a spinal deformity. The aim of this study was to develop a core outcome set (COS) that will facilitate benchmarking within and between the 5 countries of the Nordic Spinal Deformity Society (NSDS) and other registries worldwide...

A 16-year-old girl who had Morquio syndrome presented with severe bilateral hip pain and limited mobility because of bilateral hip osteoarthritis and fixed flexion deformities. She was wheelchair bound for the previous 6 months. Cervical spine flexion-extension views showed mild subluxation (<3 mm), and there was thoracolumbar spine kyphosis. Magnetic resonance imaging of the cervical and thoracolumbar spine showed hypoplasia of the odontoid and vertebral bodies, but no spinal cord compression. Bilateral cemented total hip arthroplasty was performed through a posterior approach under general anesthesia with fiberoptic intubation...

BACKGROUND/PURPOSE: Patients are always concerned about their postoperative appearance before surgery for facial deformity correction. The present study investigated the facial profile and frontal changes following two-jaw surgery. METHODS: Forty patients who underwent two-jaw surgery were divided by the amount of mandibular setback (group I: ≤8 mm and group II: >8 mm). Cephalometric radiograms (lateral and frontal) were collected and analyzed at three intervals: preoperatively (T1), immediately postoperatively (T2), and final follow-up (T3)...

Scoliosis is an abnormal curvature of the spine. One or several curves of more than 10 degrees in the frontal plane can be seen with the rotation of vertebrae in the axial plane, which modifies sagittal curves. In addition to esthetic harm, the morbidity of a scoliosis depends on the extent of the deformation. Treatment, whether it be orthopedic or surgical, is aggressive and never completely cures the condition. At best the deformation will be stabilized at the end of growth. Therefore, it is essential to detect any slight curve and quickly identify any potential progressive form in order to treat it...

Caudal Regression Syndrome (CRS) is a rare disorder which consists of abnormalities in the lumbosacral spine, rectum, urinary system and lower limbs. These abnormalities also include orthopaedic deformities, such as hip dislocation, knee-flexion contracture with popliteal webbing and talipes equinovarus. Because of the rarity of this condition, few medical personnel are aware of it. Here, we present a case of CRS in a 15-year-old girl with pressure ulcers on the lateral malleolus and plantar surface of the foot, which had come into contact with the wheelchair footrest...

Many orthopedic articles describe advances in surgical techniques and implants used in pediatric scoliosis surgery. However, even though postoperative spine imaging constitutes a large portion of outpatient musculoskeletal pediatric radiology, few, if any, radiology articles discuss this topic. There has been interval advancement over the last decades of the orthopedic procedures used in the treatment of spinal scoliosis in adolescents with idiopathic scoliosis. The goal of treatment in these patients is to stop the progression of the curve by blocking the spinal growth and correcting the deformity as much as possible...
