Abstract
Objective: This study aimed to evaluate the clinical effects of a posterior surgical strategy for rigid angular kyphosis in the healed late stage of thoracolumbar tuberculosis, especially emphasizing the management of adjacent segment degeneration.Design: This is a retrospective study.Setting: This study was performed at Union Hospital, Tongji Medical College, Wuhan, ChinaParticipants: A total of 11 patients with rigid angular kyphosis in the healed late stage of thoracolumbar tuberculosis were included.Interventions: Each patient underwent posterior vertebral column resection (PVCR) for the correction of kyphosis, and mPSO was used for decompression of the stenotic adjacent segments.Outcome measures: Postoperatively, clinical and radiological evaluation was assessed.Results: Eight patients underwent PVCR, and 4 patients underwent both the PVCR and mPSO procedures. The average operation time was 6.5 hours (4.5-7.5 hours). The kyphotic angle improved from 97.5 ± 21.3° preoperatively to 45.4 ± 17.2° postoperatively. According to the ASIA grading system, 8 patients recovered to grade E, 2 to grade D, and 1 patient to grade A.Conclusion: PVCR is an effective procedure for the correction of rigid angular kyphosis in patients with spinal tuberculosis. Adjacent segment degeneration is an important risk factor for causing neurologic deficits, and posterior surgical management for angular kyphosis of thoracolumbar tuberculosis and spinal decompression using mPSO are recommended.

Abstract
OBJECTIVE Late-onset neurological deficits are a rare complication of spinal tuberculosis that may be caused by proximal adjacent segment degeneration (ASD) above the kyphus. The objective of this study was to report several cases of neurological deficits due to proximal ASD in patients with post-tuberculous kyphotic deformity and discuss the characteristics of the authors' corrective surgical technique. METHODS The inclusion criteria in this study were severe angular kyphosis due to a post-tuberculous kyphotic deformity and a late-onset neurological deficit. The cause of these deficits was related to a lesion in the proximal cephalad portion of the kyphotic deformity. Surgical intervention, including decompression and compromised restoration of the sagittal imbalance, was performed in all patients. Preoperative surgical planning with a radiological evaluation included CT, plain radiograph, and MRI studies. Clinical outcomes were evaluated using the American Spinal Injury Association Impairment Scale and the Oswestry Disability Index (ODI). RESULTS The main goal of our surgical technique was the correction of sagittal malalignment by positioning the patient's head above the kyphotic deformity on the sagittal plane, excluding aggressive osteotomy. The neurological symptoms showed immediate improvements postoperatively, except in 1 patient. Compared to the preoperative value of 66.9, the mean ODI score improved to 42.6 at the final follow-up for all patients. Preoperatively, the mean values of the angles of deformity and the sagittal vertical axis were 99.7° and 157.7 mm, respectively, and decreased to 75.3° and 46.0 mm, respectively, at the final follow-up. No major complications were observed, and the patients' self-satisfaction was high with respect to both cosmetic and functional outcomes. CONCLUSIONS Clinicians should be aware of the degeneration of the vertebrae above the kyphotic segment in patients with post-tuberculosis deformity. Successful neurological recovery and compromised sagittal balance could be obtained by using our "head on kyphus" surgical concept.

Abstract
The natural healing of spinal tuberculosis occurs by spontaneous fusion of vertebral bodies with or without kyphotic deformity. Late-onset paraplegia secondary to the fracture of fusion mass in tuberculosis is one of the rare conditions which have not been extensively reported. A 56-year-old male patient sustained road traffic accident was diagnosed with a fracture of fusion mass in already healed tuberculosis. He was presented with weakness in both the lower limbs with ASIA-C grading of spinal cord injury. He was treated with posterior instrumented stabilization and decompression. The patient recovered well postoperatively and had regained his complete power of both lower limbs. Late-onset paraplegia in old healed spinal tuberculosis is a well-known entity that may be caused due to transaction of the cord by a bony ridge or when the formed granulation or fibrous tissue constricts the cord. Fusion mass fractures are not very uncommon in conditions such as ankylosing spondylitis or diffuse idiopathic skeletal hyperostosis. Traumatic fractures tend to occur at the adjacent vertebral bodies to the fused ones as the biomechanical stress at the junctional site is far higher than at the center of the fused mass. In healed spinal tuberculosis, resultant deformity would be kyphosis. The angle of kyphosis is directly proportional to the resulting neurological deficit. Fractures of fused mass in healed tuberculosis are similar to the fractures in other ossifying bone lesions. The purpose of this article is to document the rare possibility of late-onset paraplegia in uninstrumented old healed spinal tuberculosis with kyphotic deformity, due to the fracture of fusion mass as seen in ankylosing spondylitis.

Abstract
Background Severe post-tubercular kyphosis with late-onset neurological deficits is difficult to treat, with high risk of neurological complications. This study retrospectively evaluates the efficacy and safety of posterior vertebral column resection (PVCR) for treating severe post-tubercular kyphosis with late-onset neurological deficits. Methods From January 2012 to December 2015, 13 patients with severe post-tubercular kyphosis underwent PVCR. All these patients were of late-onset neurological deficits. The operative time, blood loss, preoperative and postoperative kyphotic angles, sagittal vertical axis (SVA), neurological status, and complications were recorded. The preoperative and postoperative Oswestry Disability Index (ODI) scores and visual analog scale (VAS) scores for back pain were compared. The American Spinal Injury Association (ASIA) grading system was used to evaluate neurological function. Results The mean postoperative follow-up period was 28.6 months. The mean operative time was 388 ± 46 min. The mean blood loss was 2554 ± 1459 ml. The mean preoperative and postoperative kyphotic angles were 93.7 ± 14.4° and 31.7 ± 7.3°, respectively, with a mean correction of 62.0 ± 13.8°. The mean preoperative and postoperative SVA were 43.2 ± 44.4 mm and 17.8 ± 16.2 mm, respectively. The mean ODI score improved from 56.3 ± 5.1 preoperatively to 18.3 ± 18.5 at last follow-up. The mean VAS score improved from 6.4 ± 1.8 preoperatively to 1.8 ± 0.8 at last follow-up. Two cases had spinal cord injuries, including one complete paraplegia and one incomplete paraplegia, and a total neurological complication rate of 15.4%. The risk factors for neurological complications were summarized. Conclusions Severe post-tubercular kyphosis with late-onset neurological deficits can be corrected by PVCR carefully and properly to prevent neurological complications. In many cases with stenosis adjacent to the angular kyphosis, sufficient decompression of the spinal cord at the segments with stenosis is necessary before correcting the kyphosis.

Abstract
Late onset neurological deficit is a rare complication of spinal tuberculosis. Reactivation of the disease and compression by internal gibbus are the common causes for late onset neurological deficit. We report a rare cause of late onset paraplegia in a patient with post tubercular kyphotic deformity. The late onset neurological deficit was due to the adjacent segment degeneration proximal to the kyphotic deformity. Posterior hypertrophied ligamentum flavum and anterior disc osteophyte complex caused the cord compression. The increased stress for prolonged period at the end of the deformity was the reason for the accelerated degeneration. Patient underwent posterior decompression, posterolateral and interbody fusion. Deformity correction was not done. To our best knowledge, this is only the second report of this unusual cause of late onset paraplegia.

Abstract
Aims To address the natural history of severe post-tuberculous (TB) kyphosis, with focus upon the long-term neurological outcome, occurrence of restrictive lung disease, and the effect on life expectancy. Patients and Methods This is a retrospective clinical review of prospectively collected imaging data based at a single institute. A total of 24 patients of Southern Chinese origin who presented with spinal TB with a mean of 113° of kyphosis (65° to 159°) who fulfilled inclusion criteria were reviewed. Plain radiographs were used to assess the degree of spinal deformity. Myelography, CT and MRI were used when available to assess the integrity of the spinal cord and canal. Patient demographics, age of onset of spinal TB and interventions, types of surgical procedure, intra- and post-operative complications, and neurological status were assessed. Results All except one of the 24 patients were treated with anti-TB chemotherapy when they were first diagnosed with spinal TB. They subsequently received surgery either for neurological deterioration, or deformity correction in later life. The mean follow-up was 34 years (11 to 59) since these surgical interventions. Some 16 patients (66.7%) suffered from late neurological deterioration at a mean of 26 years (8 to 49) after the initial drug treatment. The causes of neurological deterioration were healed disease in nine patients (56.2%), re-activation in six patients (37.5%) and adjacent level spinal stenosis in one patient (6.3%). The result of surgery was worse in healed disease. Eight patients without neurological deterioration received surgery to correct the kyphosis. The mean correction ranged from 97° to 72°. Three patients who were clinically quiescent with no neurological deterioration were found to have active TB of the spine. Solid fusion was achieved in all cases and no patient suffered from neurological deterioration after 42 years of follow-up. On final follow-up, six patients were noted to have deceased (age range: 47 years to 75 years). Conclusion Our study presents one of the longest assessments of spinal TB with severe kyphosis. Severe post-TB kyphosis may lead to significant health problems many years following the initial drug treatment. Early surgical correction of the kyphosis, solid fusion and regular surveillance may avoid late complications. Paraplegia, restrictive lung disease and early onset kyphosis might relate to early death. Clinically quiescent disease does not mean cure. Cite this article: Bone Joint J 2017;99-B:1381–8.

We report a patient with post-tubercular kyphotic deformity in whom the late onset paraplegia is caused by ossified ligamentum flavum above the level of kyphotic deformity. The deficit was attributable to the ossified ligamentum flavum and she recovered completely following posterior decompression and instrumented posterolateral fusion. To the best of our knowledge, this is the first report of this unusual cause of late onset paraplegia.

Abstract
Introduction Tuberculosis of the spine is a still a common disease entity, not only in developing countries but is also returning in developed countries especially in the immune-compromised patients. Conservative treatment with chemotherapy is still the main stay of treatment. This article focuses on the clinical and radiological outcomes, and problems with conservative treatment. Method The available literature of anti-tuberculosis chemotherapy in managing spinal tuberculosis was reviewed. Data sources included relevant literature of the English language identified through Medline search from 1946 to 2011. Personal experience and unpublished reviews from the authors’ institution were also included. Results Although majority of patients respond well to anti-tuberculosis chemotherapy, about 15 % of them develop paradoxical response. The Medical Research Council (MRC) studies have shown that for patients without significant neurological deficits, operative and conservative treatment could produce the same clinical outcome at 15 years follow-up. Patients treated operatively with debridement and spinal fusion with strut graft had faster bony fusion and less kyphotic deformity. In contrast, those treated with drugs alone or with simple debridement without fusion may result in disease reactivation, severe kyphosis or late instability, which in turn may lead to late-onset Pott’s paraplegia, back pain, sagittal imbalance and compromised pulmonary function that are difficult or risky to treat. Conclusion Recognition of the clinical and radiologic features of these late sequels is important for the management. Prevention of deformity in the early disease has been added to the modern standard of treatment of TB spine.

Abstract
BACKGROUND The patients with healed severe progressive tubercular kyphosis may develop late-onset paraplegia. A particular subgroup of these children (Type IB progression) may benefit from the management principles of congenital kyphosis. Self-correction may be observed by selective continued growth of anterior vertebral epiphyseal end-plates over the posterior fused mass. We report a series of cases with posterior fusion of progressive post-tubercular kyphosis with an aim to prevent further progression of kyphosis and to assess if any gradual self correction is seen in followup. MATERIALS AND METHODS Twelve children fulfilling inclusion criteria of clinicoradiological, hematological diagnosis of healed spine TB having no or <2 spine at risk signs having documented progression of kyphosis and neural deficit underwent posterior fusion in situ without instrumentation, using autogenous iliac crest grafts as well as allograft donor bone graft. They were followed up to maximum of 5 years. RESULTS All 12 children had a progressive increase in angle preoperatively. Mean followup was 3.6 years. Post surgery, 66% showed a clinical improvement and correction, 25% had static angle, and worsening in one patient. Thus, overall 91% have a favorable result. CONCLUSION The mechanism of correction of deformity in presence of posterior fusion is continued growth of the anterior epiphyseal end plates and hence this leads to selective differential anterior column growth giving gradual correction of kyphosis. This avoids anterior, technically demanding and complex, internal gibbus surgeries. This procedure is simple, safe, and less morbid with good results, avoiding long term disability to the patients in selected group of patients.

Abstract
The dismal outcome of tuberculosis of the spine in the pre-antibiotic era has improved significantly because of the use of potent antitubercular drugs, modern diagnostic aids and advances in surgical management. MRI allows the diagnosis of a tuberculous lesion, with a sensitivity of 100% and specificity of 88%, well before deformity develops. Neurological deficit and deformity are the worst complications of spinal tuberculosis. Patients treated conservatively show an increase in deformity of about 15 degrees . In children, a kyphosis continues to increase with growth even after the lesion has healed. Tuberculosis of the spine is a medical disease which is not primarily treated surgically, but operation is required to prevent and treat the complications. Panvertebral lesions, therapeutically refractory disease, severe kyphosis, a developing neurological deficit, lack of improvement or deterioration are indications for surgery. Patients who present with a kyphosis of 60 degrees or more, or one which is likely to progress, require anterior decompression, posterior shortening, posterior instrumented stabilisation and anterior and posterior bone grafting in the active stage of the disease. Late-onset paraplegia is best prevented rather than treated. The awareness and suspicion of an atypical presentation of spinal tuberculosis should be high in order to obtain a good outcome. Therapeutically refractory cases of tuberculosis of the spine are increasing in association with the presence of HIV and multidrug-resistant tuberculosis.

Abstract
Spinal deformity and paraplegia/quadriplegia are the most common complications of tuberculosis (TB) of spine. TB of dorsal spine almost always produces kyphosis while cervical and lumbar spine shows reversal of lordosis to begin with followed by kyphosis. kyphosis continues to increase in adults when patients are treated nonoperatively or by surgical decompression. In children, kyphosis continues to increase even after healing of the tubercular disease. The residual, healed kyphosis on a long follow-up produces painful costopelvic impingement, reduced vital capacity and eventually respiratory complications; spinal canal stenosis proximal to the kyphosis and paraplegia with healed disease, thus affecting the quality and span of life. These complications can be avoided by early diagnosis of tubercular spine lesion to heal with minimal or no kyphosis. When tubercular lesion reports with kyphosis of more than 50 degrees or is likely to progress further, they should be undertaken for kyphus correction. The sequential steps of kyphosis correction include anterior decompression and corpectomy, posterior column shortening, posterior instrumentation, anterior bone grafting and posterior fusion. During the procedure, the spinal cord should be kept under vision so that it should not elongate. Internal kyphectomy (gibbectomy) is a preferred treatment for late onset paraplegia with severe healed kyphosis.

Abstract
STUDY DESIGN Case report and review of the literature. OBJECTIVE To report 2 patients, with a history of thoracic tuberculosis, in whom ossification of ligamentum flavum (OLF) was found adjacent to progressive kyphosis and resulted in incomplete paralysis. The relevant literature was also to be reviewed. SUMMARY OF BACKGROUND DATA Progressive kyphosis is the most common cause of late onset paralysis after spinal tuberculosis. However, OLF related to tuberculous kyphosis is rarely observed and this makes surgical treatment become very difficult. METHODS Clinical history, laboratory examination, and radiographic findings of the 2 patients were described. Posterior laminectomy and instrumented fusion were performed for both 2 patients, but additional osteoectomy was performed through posterolateral zygapophysial approach in only 1 patient in whom the kyphotic deformity was partially corrected. A review of the relevant literature was also done. RESULTS Two patients were observed up for 2 and 6 years, respectively. Neurologic status was significantly improved after operation and no further kyphosis developed. To our knowledge, only 1 article had reported 2 similar cases of spinal stenosis above a healed tuberculous kyphosis. CONCLUSION OLF related to tuberculous kyphosis was rarely observed. The local instability and repetitive stimulus of excessive stress could lead to development of OLF. Our experience suggested that decompression of OLF was more important than correction of kyphotic deformity to improve the neurologic status in these patients.

METHODS (1) Medical and radiological records of 10 patients diagnosed as vertebral osteomyelitis and treated elsewhere but later admitted to the NSIC were reviewed retrospectively. (2) Medical literature on vertebral osteomyelitis were reviewed. RESULTS (1) Case review: Before the study, four of the 10 patients TVO had been diagnosed based on positive bacteriology. Of the other six, the diagnosis of PVO had been made in one based on positive blood culture of staphylococcus while in another without any positive result of bacteriology. The diagnosis had been uncertain in four because of negative results of both bacteriology and histology on both tuberculous and pyogenic infection. The author made the diagnosis of TVO in all 10 cases based on clinical manifestations and plain radiographs. Highly raised ESR with moderate rise of or normal WBC in eight cases supported TVO. Computer tomography and magnetic resonance imaging did not contribute to the differential diagnosis. Laminectomy in five patients led to some clinical improvement. The five patients without surgery deteriorated. Two of them died. (2) LITERATURE REVIEW: A total of 188 articles were reviewed. The crucial role of plain radiographs in the diagnosis of TVO and the high incidence of false-negative of tuberculosis in both bacteriological and histological tests were neglected in most articles. Polymerase chain reaction (PCR) was more reliable in diagnosing tuberculosis. CONCLUSION Clinical manifestations, discrepancy between ESR and WBC, plain radiographs and PCR are keys to a correct diagnosis of TVO.
