The development of spinal deformity in children with underlying neurodisability can affect their ability to function and impact on their quality of life, as well as compromise provision of nursing care. Patients with neuromuscular spinal deformity are among the most challenging due to the number and complexity of medical comorbidities that increase the risk for severe intraoperative or postoperative complications. A multidisciplinary approach is mandatory at every stage to ensure that all nonoperative measures have been applied, and that the treatment goals have been clearly defined and agreed with the family. This will involve input from multiple specialities, including allied healthcare professionals, such as physiotherapists and wheelchair services. Surgery should be considered when there is significant impact on the patients’ quality of life, which is usually due to poor sitting balance, back or costo-pelvic pain, respiratory complications, or problems with self-care and feeding. Meticulous preoperative assessment is required, along with careful consideration of the nature of the deformity and the problems that it is causing. Surgery can achieve good curve correction and results in high levels of satisfaction from the patients and their caregivers. Modern modular posterior instrumentation systems allow an effective deformity correction. However, the risks of surgery remain high, and involvement of the family at all stages of decision-making is required in order to balance the risks and anticipated gains of the procedure, and to select those patients who can mostly benefit from spinal correction.

Aims

To describe the clinical, radiological, and functional outcomes in patients with isolated congenital thoracolumbar kyphosis who were treated with three-column osteotomy by posterior-only approach.

Aims

HIV predisposes patients to opportunistic infections. However, with the establishment of Highly Active Anti-Retroviral Therapy (HAART), patients’ CD4 counts are maintained, as is a near normal life expectancy. This study aimed to establish the impact of HIV on the bacteriology of spondylodiscitis in a region in which tuberculosis (TB) is endemic, and to identify factors that might distinguish between them.

Aims

The surgical treatment of tuberculosis (TB) of the spine consists of debridement and reconstruction of the anterior column. Loss of correction is the most significant challenge. Our aim was to report the outcome of single-stage posterior surgery using bone allografts in the management of this condition.

Adolescent idiopathic scoliosis (AIS) is a complex 3D deformity of the spine. Its prevalence is between 2% and 3% in the general population, with almost 10% of patients requiring some form of treatment and up to 0.1% undergoing surgery. The cosmetic aspect of the deformity is the biggest concern to the patient and is often accompanied by psychosocial distress. In addition, severe curves can cause cardiopulmonary distress. With proven benefits from surgery, the aims of treatment are to improve the cosmetic and functional outcomes. Obtaining correction in the coronal plane is not the only important endpoint anymore. With better understanding of spinal biomechanics and the long-term effects of multiplanar imbalance, we now know that sagittal balance is equally, if not more, important. Better correction of deformities has also been facilitated by an improvement in the design of implants and a better understanding of metallurgy. Understanding the unique character of each deformity is important. In addition, using the most appropriate implant and applying all the principles of correction in a bespoke manner is important to achieve optimum correction.

In this article, we review the current concepts in AIS surgery.

Introduction and aim:. With up to 70% of adults with tuberculosis in Sub-Saharan Africa infected with human immunodeficiency virus (HIV), severe spinal tuberculosis presents a different set of clinical and surgical challenges. To overcome the disadvantages of various traditional techniques, particularly in patients who are HIV-positive with opportunistic pulmonary pathology, and to obviate the need to violate the diaphragm in the lower thoracic and upper lumbar spine, a posterior vertebral column resection through a single posterior approach was proposed. The aim of this study is to report on the early results of the single-stage posterior only vertebral column resection. Method:. A total of 12 patients (10 females and 2 males) seen at CMJAH between January 2007 and January 2011 underwent a single-stage posterior only posterior vertebral column resection, and were retrospectively reviewed. The indications for PVCR are essentially the same as those for 360 degrees decompression and fusion. The mean follow-up period was 15.8 months (range 5 to 44 months). Results:. Eleven allografts and 1 autograft were placed centrally and secured. The kyphosis correction averaged 17.83 degrees (range 0 to 45 degrees); with no loss of correction at last follow-up. The mean number of vertebrae removed was 1.325 (0.75 to 2) with the mean instrumented levels of 3.8 (2 to 7). The mean duration of surgery was 266.6 minutes (140 to 415 mins), the mean intra-operative blood loss was 712.5 mls (350–2100 mls). No loosening or breakage of screws occurred. The mean Frankel neurology grading at last follow-up was D (B to E). Conclusion:. Early results of single-stage only PVCR are gratifying, particularly in patients with decreased pulmonary functions who will not withstand to adverse effects of anterior surgery and 2 stage-surgery. It is an effective surgical technique but technically demanding procedure with possible risks of major complications

Objective. Posterior vertebral column resection (PVCR) is indicated in the management of severe rigid spine deformities. It is a complex surgical procedure and is only performed in a few spine centres due to the technical expertise required and associated risk. The purpose of this study is to review the indications, surgical challenges and outcomes of patients undergoing PVCR. Methods. 12 patients with severe spinal deformities who underwent PVCR were retrospectively reviewed after a follow-up of 2 years. Surgery was performed with the aid of motor evoked spinal cord monitoring and cellsaver when available. The average surgical duration was 310 minutes (100–490). The average blood loss was 1491 ml (0–3500). The indication for PVCR was gross deformity and myelopathy which was due to congenital spinal deformities and one case of old tuberculosis. Clinical records and the radiographic parameters were reviewed. Results. Kyphosis of an average of 72 degrees was corrected to 28 degrees. The associated scoliosis was corrected from an average of 49.2 to 21.2 degrees. Ten patients improved neurologically to ASIA D and E. One patient deteriorated markedly, required revision with no initial improvement but reached ASIA E at 6 months after surgery. Four patients had associated syringomyelia. All were re-scanned at 1 year. The three with small syrinx's demonstrated no progression on MRI and the large syrinx resolved completely. In addition to the neurological deterioration, complications included 1 right lower lobe pneumonia. Conclusion. PVCR is an effective option to correct complex rigid kyphoscoliosis. In addition it allows excellent circumferential decompression of the cord and neurological recovery. When the congenital scoliosis is associated with syringomyelia with no other cause evident, it may allow resolution of the syrinx. Key words: Posterior vertebral column resection, severe spinal deformities, myelopathy, syringomyelia. NO DISCLOSURES

We report the results of vertebral column resection (VCR) for paediatric patients with spinal deformity. A total of 49 VCRs in paediatric patients from four university hospitals between 2005 and 2009 with a minimum two-year follow-up were retrospectively identified. After excluding single hemivertebral resections (n = 25) and VCRs performed for patients with myelomeningocele (n = 6), as well as spondylectomies performed for tumour (n = 4), there were 14 patients who had undergone full VCR at a mean age of 12.3 years (6.5 to 17.9). The aetiology was congenital scoliosis in five, neuromuscular scoliosis in three, congenital kyphosis in two, global kyphosis in two, adolescent idiopathic scoliosis in one and secondary scoliosis in one. A total of seven anteroposterior and seven posterolateral approaches were used.

The mean major curve deformity was 86° (67° to 120°) pre-operatively and 37° (17° to 80°) at the two-year follow-up; correction was a mean of 54% (18% to 86%) in the anteroposterior and 60% (41% to 70%) in the posterolateral group at the two-year follow-up (p = 0.53). The mean Scoliosis Research Society-24 total scores were 100 (92 to 108) for the anteroposterior and 102 (95 to 105) for the posterolateral group. There was one paraparesis in the anteroposterior group necessitating urgent re-decompression, with a full recovery.

Patients undergoing VCR are highly satisfied after a successful procedure.
