Treatment of congenital kyphosis with severe angular dysplastic spine in children with myelomeningocele (MMC) is one of the most difficult spinal procedures. Most of the surgeons support kyphectomy with long segmental spinal instrumentation and postoperative immobilization by thoracolumbosacral orthosis. Several spinal deformities are seen frequently in patients who have MMC. The deformity may be congenital or paralytic. Congenital lumbar kyphosis is less common, but most difficult in patients with MMC, occurring in 10–20% of patients. Most curves are congenital and rigid, often more than 80° at birth, and rapidly progresses. With progression of
Introduction: Minimally invasive augmentation techniques of vertebral bodies have been widely used in the treatment of painful osteoporotic vertebral compression fractures (VBCFs). Kyphoplasty seems to achieve pain relief and improvement in quality of life. However, the effect of kyphoplasty on the height and the
To evaluate our results of treatment of kyphosis following osteoporotic fractures of the last 3 years. 28 women with a mean age of 63,2 years were treated for a painful
Twenty-one patients with rigid kyphosis treated by single stage vertebral column resection were evaluated retrospectively. The average age was 12 years and kyphosis was 75 degrees. Thirteen cases were due to tuberculosis while 8 had a congenital anomaly, 5 cases had neurologic deficit. Radiographs, CT and MRI scans were used for preoperative evaluation. The survey included transpedicular vertebral decancellisation, spinal column shortening, interbody fusion and segmental spinal instrumentation. At 36 months [36–60] follow up, the average correction was 61% and all cases adequately fused. Complications included one case with postoperative neurological deterioration and one patient with decompensated lordosis.
A variety of surgical methods and strategies have been demonstrated for Andersson lesion (AL) therapy. In 2011, we proposed and identified the feasibility of stabilizing the spine without curettaging the vertebral or discovertebral lesion to cure non-kyphotic AL. Additionally, due to the excellent reunion ability of ankylosing spondylitis, we further came up with minimally invasive spinal surgery (MIS) to avoid the need for both bone graft and lesion curettage in AL surgery. However, there is a paucity of research into the comparison between open spinal fusion (OSF) and early MIS in the treatment of AL. The purpose of this study was to investigate and compare the clinical outcomes and radiological evaluation of our early MIS approach and OSF for AL. A total of 39 patients diagnosed with AL who underwent surgery from January 2004 to December 2022 were retrospectively screened for eligibility. Patients with AL were divided into an MIS group and an OSF group. The primary outcomes were union of the lesion on radiograph and CT, as well as the visual analogue scale (VAS) and Oswestry Disability Index (ODI) scores immediately after surgery, and at the follow-up (mean 29 months (standard error (SE) 9)). The secondary outcomes were total blood loss during surgery, operating time, and improvement in the radiological parameters: global and local kyphosis, sagittal vertical axis, sagittal alignment, and chin-brow vertical angle immediately after surgery and at the follow-up.Aims

Introduction: Since 1989 vertebral resection with modified Luque fixation has been the procedure of choice for correction of myelomeningocele
Aim: Presentation of the technique, the mistakes and the results of a new minimal invasive surgical procedure for reduction and augmentation of pathological fractures of the vertebrae in spine. Patients and Methods: 12 patients (2 men / 10 women) with mean age 68 years (54–73) with pathological vertebral underwent kyphoplasty. The mean pain according to VAS was 7, 3 (6–10) and the mean follow up time is 8 months (5–14). 11/12 patients (20 vertebrae) had osteoporotic vertebral and 1/12 (1 vertebra) had metastatic lesion. 8/21 vertebrae were in thoracic spine and 13/21 in lumbar spine. In 20/21 the procedure was transcervical to the vertebra and in 1/21 was out of the cervix. 11/12 patients had
Background: A 9- year-old child with osteogenesis imperfecta and severe cervical kyphosis associated with wedged vertebrae and progressive neurological deterioration is presented. There is no report of upper cervical kyphosis associated with wedged vertebrae in osteogenesis imperfecta in the literature. We discuss the methods and difficulties in the surgical management of this condition and to highlight the appropriate surgical approach. Methods: Methods:A 9-year-old girl presented with progressive cervical kyphosis and quadriparesis. At the age of 3 years she underwent posterior cervical fusion (C1–C6) for instability and deformity. Radiological and laboratory investigations confirmed the diagnosis of osteogenesis imperfecta. Radiographs of the cervical spine revealed a

Introduction. Pedicle subtraction osteotomy is a powerful technique for correcting sagittal imbalance in ankylosing spondylitis. There has been significant perioperative morbidity associated with this technique in the peer review literature. We present the Royal National Orthopaedic Hospital experience with a single surgeon retrospective study that was conducted to evaluate the outcomes in patients who underwent lumbar pedicle subtraction osteotomy for the correction of thoracolumbar
Introduction. Vertebral osteoporotic fracture increases both elastic and time-dependent (‘creep’) deformations of the fractured vertebral body during subsequent loading. This is especially marked in central and anterior regions of the vertebral body, and could explain the development of
The K2M MESA Rail is a new implant with a unique beam-like design which provides increased rigidity compared with a standard circular rod of equivalent diameter potentially allowing greater control and maintenance of correction. The aim of this study was to review our early experience of this implant. We retrospectively reviewed the case notes and radiographs of all consecutive cases of spinal deformity correction in which at least one rail was used. All radiological measurements were made according to the Scoliosis Research Society definitions. Since June 2012 thirty-three cases of spinal deformity correction were performed using the K2M Rail system. One case was excluded as there were no pre-operative radiographs. Median age was 15 years; there were 23 females. There were 26 scoliosis cases of which two had associated Chiari malformation, three were neuromuscular, and the remainder were adolescent idiopathic cases. Six patients had
Introduction. Vertebral osteoporotic fracture increases both elastic and time-dependent ('creep') deformations of the fractured vertebral body during subsequent loading. The accelerated rate of creep deformation is especially marked in central and anterior regions of the vertebral body where bone mineral density is lowest. In life, subsequent loading of damaged vertebrae may cause anterior wedging of the vertebral body which could contribute to the development of

Study design: Retrospective clinical study. Objective: To assess the results of spondylodiscitis treated by surgery. To compare debridement and instrumentation with debridement without instrumentation. Methods: Between February 1989 and February 2008, 29 patients with a diagnosis of spondylodiscitis underwent surgery. The mean age at the time of surgery was 57 years (range, 12–84). The average follow-up period was 8.4 years (range, 1–20). Pyogenic spondylodiscitis was diagnosed in 17 cases and tuberculous spondilodyscitis in 12 cases. The results of 14 patients treated by debridement and instrumentation (Group I) were compared with 15 patients who received debridement without instrumentation (GroupII). The saggital angle, loss of correction and clinical results were compared. Results: The clinical presentation was: intractable pain 20.7%, severe pain irradiating lower limbs 20.7%, pain and neurologic deficit 44.8%, pain and

The lumbar spine consists of a mobile segment of 5 vertebrae, which are located between the relatively immobile segments of the thoracic and sacral segments. The bodies are wider and have shorter and heavier pedicles, and the transverse processes project somewhat more laterally and ventrally than other spinal segments. The laminae are shorter vertically than are the bodies and are bridged by strong ligaments. The spinous processes are broader and stronger than are those in the thoracic and cervical spine. Internal fixation as an adjunct to spinal fusion has become increasingly popular in recent years. Stainless steel or titanium plates or rods are longitudinally anchored to the spine by hooks or pedicle screws. Powerful forces can be applied to the spine through these implants to correct deformity. Implants provide immediate rigid spinal immobilization, which allows for early patient mobilization, and provides a more optimal environment for bone graft incorporation. Numerous clinical and experimental studies demonstrate higher fusion rates in patients with rigid internal fixation than in controls without instrumentation. Although various implants are available, pedicle fixation systems are the most commonly used implant type in the lumbosacral spine. The large size of the lumbar pedicles minimizes the number of instrumented motion segments required to achieve adequate stabilization. Many authors have reported loss of postoperative deformity correction after transpedicular screw fixation, ranging from 2.5 degrees to 7.1 degrees. The general preference is to stabilize the fractured vertebra by fusing one level above and one level below. With this technique, the rate of loss of correction is high. At our institution, we routinely stabilize the unstable thoracolumbar fractures by fusing one level above and one level below. In addition, we put screws into the pedicle(s) of fractured vertebrae. The reason for this is the following:. To correct the deformed body of the fractured vertebra for better load sharing. To make use of the pedicles of the fractured vertebra for superior rotatory stabilization. To avoid the need for the inclusion of additional levels, thereby preserving motion segments. To avoid the need for possible anterior spinal fusion and instrumentation. To obtain a better correction of a
Purpose: The purpose of this biomechanical study was to assess: (1) the effect of thoracic vertebral compression fracture (VCF) on kyphosis and physiologic compressive load path, and (2) the effect of balloon kyphoplasty and spinal extension on restoration of normal geometric and loading alignment. Methods: Six fresh human thoracic specimens, each consisting of three adjacent vertebrae were used. In order to create a VCF, IBTs were placed transpedicularly into the middle VB and cancellous bone was disrupted by inflation of IBTs. After cancellous bone disruption the specimens were compressed using bilateral loading cables until a fracture was observed. Fracture reduction by spinal extension, and then by balloon kyphoplasty was performed under a physiologic compressive preload of 250 N. The vertebral body heights,
