We describe a previously healthy, non-leukaemic young male presenting with neurological deficit and a pathological dislocation of D8 over D9 vertebra. The magnetic resonance imaging showed an enhancing soft tissue tumour. His basic laboratory workup as well as a bone marrow biopsy was normal. Through a single midline posterior approach, he underwent a decompressive laminectomy of D8 and D9 vertebra, anterior column reconstruction with a meshed titanium cage and posterior pedicle screw instrumentation. The histological diagnosis of granulocytic sarcoma was confirmed by appropriate immuno-histochemical studies. He received postoperative radiotherapy following which his wound dehiscesed and the tumour fungated and spread to his left thigh. He declined chemotherapy and unfortunately expired 9 months later. This case is presented to draw attention to the unusual presentation and to stress that granulocytic sarcoma should be kept in mind when making the differential diagnosis in patients with signs of spinal cord compression even in non-leukaemic individuals.

Background  Infectious spondylodiscitis is a debilitating condition and evidence-based medicine dictates confirming the diagnosis before treatment. Computed tomography-guided spinal biopsy plays a major role and hence we would like to determine its utility in current clinical practice. Purpose  The purpose of this study is to determine the percentage of confirmatory positives of CT-guided spinal biopsy in patients who were clinicoradiologically diagnosed with infectious spondylitis. Material and Methods  A retrospective analysis of patients who underwent CT-guided biopsy for suspected infectious spondylodiscitis from 2017 to 2021 in a tertiary medical center was done. The data were filtered and obtained from the electronic database of the institution. Results  In all, 259 patients underwent CT-guided biopsy of the spine. The procedure provided confirmatory results in 149 (57.5%) biospecimens. Histopathology examination was confirmatory in 95 (36.6%) of the 241 biospecimens sent. The Mycobacteria Growth Indicator Tube (MGIT) was confirmatory in 51 (19.9%) of the 250 biospecimens sent and drug resistance was seen in 6/51 (11.7%) biospecimens. Xpert TB provided confirmatory results in 72 (27.8%) of the 254 biospecimens sent and rifampicin resistance was seen in 16/72 (22.2%) biospecimens. Bacterial culture was confirmatory in 29 (11.2%) of the 250 biospecimens sent. The complication documented in this study was 0.3%. Conclusion  CT-guided spinal biopsy for suspected vertebral osteomyelitis is a safe and effective minimally invasive procedure. It demonstrates a positive yield in more than half of the patients. Knowing the outcome, the patients can be appropriately counseled prior to the procedure. CT-guided biopsy results were affected by prior administration of ATT (antitubercular therapy) in suspected tuberculous spondylitis patients., Competing Interests: Conflict of Interest None declared., (Indian Radiological Association.

Study Design: Retrospective case series., Purpose: This study aimed to analyze how the sagittal spinopelvic alignment is influenced by an attempted surgical reduction of the L5-S1 segment in patients with high-grade spondylolisthesis (HGS)., Overview of Literature: Conventional treatment strategies stress the importance of achieving fusion across the lumbosacral junction in patients with HGS. The role of reduction in this subset of patients is controversial., Methods: This is a retrospective case series of 35 patients with Meyerding grades III, IV, or V spondylolisthesis who underwent surgical treatment in our institution. Before and after surgery, we took standing lateral radiographs from L1 vertebra to pelvis, including the femoral heads, and measured the slip grade, pelvic incidence, sacral slope, pelvic tilt, lumbosacral angle, and lumbar lordosis. Patients were subdivided into "balanced" and "unbalanced" pelvis groups. To determine the effect and correlation of reduction on these spinopelvic parameters, we statistically compared the pre- and postoperative measurements., Results: The average follow-up was 9 months (range, 3-169 months). Slip grade improved from an average 74.0%±13.2% to 30.0%±14.0% (p<0.001), and lumbosacral angle reduced from an average 32.0°±11.6° to 6.0°±0.6° (p<0.001). Although the pelvic tilt was reduced, this was not significant. There was a modest negative correlation between the reduction in slip grade and the increase in sacral slope (r=-0.3, p=0.06). At follow-up, five patients improved, from an unbalanced pelvis to a balanced pelvis. Fusion occurred in 33 patients (95%)., Conclusions: Surgical reduction of HGS restores the lumbosacral alignment. However, a similar trend is not noted with the pelvic parameters.

Study Design: Retrospective case series., Purpose: This study aimed to examine the efficacy of composite grip strength as a marker of surgical outcome in patients with moderate to severe degenerative cervical myelopathy., Overview of Literature: Degenerative cervical myelopathy causes loss of dexterity, muscle strength, and sensations in the hand. The impact of surgical management on improvement in composite grip strength has received scant attention., Methods: This retrospective study was performed on degenerative cervical myelopathy patients with a complete composite grip strength assessment between January 2013 to January 2019. The Biometrics E-link hand kit was used for the assessment. The following parameters were measured: maximum grip strength, sustained grip strength, three-jaw pinch, maximum key pinch, and sustained key pinch. The pre- and postoperative functional status was assessed using the Nurick grade and the modified Japanese Orthopaedic Association (mJOA) score., Results: A total of 40 patients were included in the study. The mean patient age was 51.9 years. The mean preoperative Nurick grade was 3.5 and the mJOA score was 10.9. The anterior approach was used in 25 patients, and the posterior approach was used in 15 patients. Four patients developed complications. Degenerative cervical myelopathy resulted in decreased handgrip and pinch strength as compared to normative Indian data. There was a significant improvement in the postoperative composite grip strength for all five parameters. There was no differential improvement between the anterior and posterior surgical groups. The improvement in the composite grip strength correlated with the improvement in functional scores., Conclusions: Composite grip strength analysis is an objective method for assessing the impact of degenerative cervical myelopathy on grip strength and monitoring the postoperative improvement. Decompressive surgery resulted in global improvement in all the parameters of composite grip strength.

Study Design: Prospective cohort study., Purpose: To evaluate the association between nutritional parameters related to postoperative surgical site infections and duration of hospital stay and intensive care unit (ICU) stay in patients undergoing major spine surgery., Overview of Literature: Malnutrition is highly prevalent in surgical patients. Malnourished patients are considered to be at higher risk for postoperative morbidity and mortality due to impaired wound healing, delayed inflammation, impaired fibroblast proliferation, and collagen synthesis. Decreased lymphocyte count also impairs the ability of the immune system to eradicate or prevent infection, which predisposes these patients to infections. However, this association between malnutrition and postoperative morbidity is not consistent across studies, thus necessitating further investigation., Methods: The values of serum albumin, prealbumin, total lymphocyte counts, and transferrin were documented preoperatively and postoperatively on day 5 for all patients undergoing major spine surgery (surgery involving instrumentation of at least three motion segments). In addition, patients' surgical wound healing status, duration of hospital stay, and duration of ICU stay in the postoperative period were documented. Finally, the statistical correlation between the nutritional markers and these complications was determined., Results: Low postoperative prealbumin levels was significantly associated with increased complication rates. ICU stay demonstrated a statistically significant association with low postoperative albumin, prealbumin, and transferrin levels. Similarly, we observed that low postoperative albumin and prealbumin levels could significantly predict the need for prolonged hospital stay in patients undergoing major spine surgery., Conclusions: The magnitude of the decrease in nutritional status due to surgery with respect to albumin and prealbumin levels is a significant (p<0.05) predictor of wound-related complications, rather than a single nutritional parameter evaluated at a point of time.

Study Design: Retrospective study., Purpose: To report the prevalence of patients with multidrug-resistant (MDR) tubercular spondylodiscitis and their outcomes. Additionally, to assess the role of Xpert MTB/RIF assay in early detection of MDR tuberculosis., Overview of Literature: MDR tuberculosis is increasing globally. The World Health Organization (WHO) has strongly recommended Xpert MTB/RIF assay for early detection of tuberculosis., Methods: From 2006 to 2015, a retrospective study was conducted on patients treated for MDR tuberculosis of the spine. Only patients whose diagnosis was confirmed using either culture and/or the Xpert MTB/RIF assay were included. Diagnostic method, treatment regimen, time taken to initiate second-line antituberculosis treatment (ATT), drug-related complications, and cost of medications were analyzed. All patients with MDR were treated according to the WHO recommendations for 2 years. The outcome parameters analyzed included clinical, biochemical, and radiological criteria to assess healing status., Results: From 2006 to 2015, a total of 730 patients were treated for tubercular spondylodiscitis. Of those, 36 had MDR tubercular spondylitis (prevalence, 4.9%), and three had extremely drug resistant tubercular spondylitis (prevalence, 0.4%). In this study, 30 patients, with a mean age of 29 years and a mean post-treatment follow-up of 24 months, were enrolled. The majority (77%) had secondary MDR, 17 (56%) underwent surgery, and 26 (87%) completed treatment for 2 years and were healed. Drug-related complications (33%) included ototoxicity, hypothyroidism, and hyperpigmentation of the skin. The average time taken for initiation of second line ATT for MDR patients with Xpert MTB/RIF assay as the diagnostic tool was 18 days, when compared to patients for whom the assay was not available which was 243 days., Conclusions: The prevalence of MDR tubercular spondylodiscitis was 4.9%. In total, 87% of patients were healed with adequate treatment. The sensitivity and specificity of the Xpert MTB/RIF assay to detect MDR was 100% and 92.3%, respectively.

Study Design: Retrospective case series., Purpose: The aim of this study was to analyze functional and radiological outcomes in patients with culture-negative pyogenic vertebral osteomyelitis (PVO)., Overview of Literature: There were only few literature available for these group of patients., Methods: Patients with biopsy-positive but culture-negative PVO were included. We analyzed records for data on demography, comorbidities, coexisting infections, neurological status, prior antibiotic therapy, pre- and postoperative erythrocyte sedimentation rate, C-reactive protein levels, and Oswestry Disability Index, and Japanese Orthopedics Association scores., Results: Sixty-one patients were included, of which data of 45 patients were available for follow-up. The patients were predominantly males (71%), with a mean age of 53.2 years. Seventy-seven percent patients had comorbidities. Echocardiography, blood culture, and urine culture were performed on 8%, 24%, and 18% of patients, respectively. Thirty-one percent patients had neurological deficits. Computed tomography-guided biopsy was performed on 67% patients. Fifty-two percent patients were treated surgically, and 48% were treated non-surgically. Nineteen percent patients were treated according to the results of cultures from other foci, and the rest were treated empirically. For the initial 2 weeks, all patients were treated with intravenous antibiotics empirically or based on culture from other foci. This treatment was followed by 10 weeks of oral cloxacillin/cephalexin for gram-positive organisms or ciprofloxacin for gram-negative organisms. The mean follow-up time was 18 months (range, 12-120 months). All patients had improvement in Japanese Orthopedics Association, Oswestry Disability Index, and Visual Analog Scale scores (p<0.001)., Conclusions: Treatment with empirical antibiotics for 12 weeks with watchful clinical and radiological follow-up yields good resolution of the disease. Further multicenter clinical research needs to be performed for obtaining an algorithmic treatment plan for these patients.

Study Design: Retrospective case series., Purpose: The aim of the study is to report the clinical characteristics, early diagnosis, management, and outcome of children with multidrug-resistant (MDR) tubercular spondylodiscitis and to assess the early detection of rifampicin resistance using the Xpert MTB/ RIF assay., Overview of Literature: MDR tuberculosis is on the rise, especially in developing countries. The incidence rate of MDR has been reported as 8.9% in children., Methods: A retrospective study of children aged <15 years of age who were diagnosed and treated for MDR tuberculosis of the spine was conducted. Confirmed cases of MDR tuberculosis and patients who had completed at least 18 months of second-line antituberculous treatment (ATT) were included. Children were treated with ATT for 24 months according to drug-susceptibility-test results. Outcome measures included both clinical and radiological measures. Clinical measures included pain, neurological status, and return to school. Radiological measures included kyphosis correction and healing status., Results: Six children with a mean age of 10 years were enrolled. The mean follow-up period was 12 months. All the children had previous history of treatment with first-line ATT, with an average of 13.6 months before presentation. Clinically, 50% (3/6 children) had psoas abscesses and 50% had spinal deformities. Radiologically, 50% (three of six children) had multicentric involvement. Three children underwent surgical decompression; two needed posterior stabilization with pedicle screws posteriorly followed by anterior column reconstruction. Early diagnosis of MDR was achieved in 83.3% (five of six children) with Xpert MTB/RIF assay. A total of 83.3% of the children were cured of the disease., Conclusions: Xpert MTB/RIF assay confers the advantage of early detection, with initiation of MDR drugs within an average of 10.5 days from presentation. The cost of second-line ATT drugs was 30 times higher than that of first-line ATT.

Purpose: This study aims to assess the accuracy of the Xpert MTB/RIF assay in the diagnosis of tubercular spondylodiscitis and to identify its role in detecting Rifampicin resistance in patients with infective spondylodiscitis., Methods: A retrospective study including 348 patients suspected to have infective spondylodiscitis was done. Tissue/pus samples obtained were sent for culture, histopathology and Xpert MTB/RIF assay. All patients who were confirmed to have tubercular spondylodiscitis and those patients who were suspected on clinico-radiological basis were also treated with anti-tuberculous chemotherapy for a period of 9 months. The efficacy of the Xpert MTB/RIF assay was assessed in terms of sensitivity and specificity when compared to culture, histopathology, and Composite reference standard (CRS)., Results: During this study period of 24 months, a total of 348 patients were treated for infective spondylodiscitis. 254 patients were treated for tuberculosis following a smear positivity, culture positivity, and histopathology report or empirically based on clinico-radiological findings. The sensitivity and specificity of the Xpert MTB/RIF assay when compared to culture were 88.4 and 63.7%, respectively. When compared to both culture and histopathology reports it was 80.9 and 80.6%. The sensitivity and specificity of the Xpert MTB/RIF assay when compared to composite reference standard were 71.2 and 100%, respectively. The sensitivity of the assay to detect Rifampicin resistance was 100%. The prevalence of Rifampicin resistance was 5.1%., Conclusion: This study recommends Xpert MTB/RIF assay for early detection of Mycobacterium tubercular spondylodiscitis and Rifampicin resistance.

Study Design: Retrospective clinical analysis., Purpose: To delineate the clinical presentation of melioidosis in the spine and to create awareness among healthcare professionals, particularly spine surgeons, regarding the diagnosis and treatment of melioidotic spondylitis., Overview of Literature: Melioidosis is an emerging disease, particularly in developing countries, associated with a high mortality rate. Its causative pathogen, Burkholderia pseudomallei , has been labeled as a bio-terrorism agent., Methods: We performed a retrospective analysis of patients who were culture positive for B. pseudomallei . Assessment of patients was performed using clinical, radiological, and blood parameters. Clinical measures included pain, neurological deficit, and return to work. Radiological measures included plain radiography of the spine and magnetic resonance imaging. Blood tests included erythrocyte sedimentation rate and C-reactive protein levels., Results: Four patients having melioidosis with spondylitis were evaluated. All of them had diabetes mellitus; three had multiple abscesses which required incision and drainage. Their clinical spectrum was similar to that of tuberculous spondylitis; all had back pain and radiology revealed infective spondylodiscitis with prevertebral and paravertebral collections with psoas abscess. Three patients underwent ultrasound-guided drainage of the psoas abscess and one had aspiration of the subcutaneous abscess. Bacteriological cultures showed presence of B. pseudomallei , and histopathology showed non-caseating granulomatous inflammation. All patients were treated with intravenous Ceftazidime for 2 weeks, followed by oral bactrim double strength and Doxycycline for 20 weeks. All patients improved with treatment and were healed at follow up., Conclusions: Melioidosis presents with a clinical spectrum similar to that of tuberculosis. A diagnosis of melioidotic spondylitis should be considered, particularly in patients with diabetes with neutrophilic leukocytosis and clinical-radiological features suggestive of infective spondylodiscitis. Bacteriological culture and histopathology helps in differentiating the two conditions. Health education for healthcare professionals is important for correctly diagnosing this disease., Competing Interests: No potential conflict of interest relevant to this article was reported.

Study Design: Non-concurrent prospective study., Purpose: To determine the functional outcome after open 'fragment' discectomy for recurrent lumbar disc herniation, and to analyze the factors that may affect the outcome., Overview of Literature: Literature search revealed only four studies where the factors affecting the outcome of a revision surgery for recurrent disc herniation have been evaluated. None of these studies analyzed for diabetes, disc degeneration and facet arthropathy. We have analyzed these features, in addition to the demographic and clinical factors., Methods: Thirty-four patients who underwent the procedure were followed up for an average period of 27.1 months. The Japanese Orthopaedic Association (JOA) score and Oswestry disability index (ODI) were used to assess the functional outcome. Age, gender, smoking, diabetic status, duration of recurrent symptoms, the side of leg pain, level and type of disc herniation, degree of disc degeneration on magnetic resonance imaging, and facet joint arthritis before first and second surgeries, were analyzed as factors affecting the outcome., Results: The average Hirabayashi improvement in JOA was 56.4%. The mean preoperative ODI was 74.5% and the mean ODI at final follow-up was 32.2%, the difference being statistically significant (p<0.01). Patients with diabetes, all of whom had poor long term glycemic control, were found to have a poor outcome in terms of ODI improvement (p=0.03)., Conclusions: Open fragment discectomy is a safe and effective surgical technique for the treatment of recurrent disc herniation. However, patients with uncontrolled diabetes may have a less favorable outcome.

Study Design: Retrospective clinical series., Purpose: To study the clinical, functional and radiological results of patients with tuberculous spondylitis with and without paraplegia, treated surgically using the "Extended Posterior Circumferential Decompression (EPCD)" technique., Overview of Literature: With the increasing possibility of addressing all three columns by a single approach, posterior and posterolateral approaches are gaining acceptance. A single exposure for cases with neurological deficit and kyphotic deformity requiring circumferential decompression, anterior column reconstruction and posterior instrumentation is helpful., Methods: Forty-one patients with dorsal/dorsolumbar/lumbar tubercular spondylitis who were operated using the EPCD approach between 2006 to 2009 were included. Postoperatively, patients were started on nine-month anti-tuberculous treatment. They were serially followed up to thirty-six months and both clinical measures (including pain, neurological status and ambulatory status) and radiological measures (including kyphotic angle correction, loss of correction and healing status) were used for assessment., Results: Disease-healing with bony fusion (interbody fusion) was seen in 97.5% of cases. Average deformity (kyphosis) correction was 54.6% in dorsal spine and 207.3% in lumbar spine. Corresponding loss of correction was 3.6 degrees in dorsal spine and 1.9 degrees in the lumbar spine. Neurological recovery in Frankel B and C paraplegia was 85.7% and 62.5%, respectively., Conclusions: The EPCD approach permits all the advantages of a single or dual session anterior and posterior surgery, with significant benefits in terms of decreased operative time, reduced hospital stay and better kyphotic angle correction.

Osteochondromas are the most common benign tumors of the bone. They mostly arise from the appendicular skeleton and present clinically in the second or third decade of life. Ostechondromas arising from the subaxial cervical spine and presenting after the 5th decade of life are extremely rare. We report a 52-year-old male patient who presented with numbness and subjective weakness of left upper and lower limbs and neck pain, and had lobulated bony hard fixed swelling in the right lower cervical paraspinal region. Radiological images revealed a bony swelling arising from C4 and C5 lamina with a cartilaginous cap and intraspinal extension. Excision biopsy with stabilisation of the spine was performed. Histopathalogical examination of the specimen confirmed the diagnosis of osteochondroma. We conclude surgical excision of such rare tumors, including the cartilaginous cap as well as the intraspinal component can reliably produce a good clinical outcome.

Study Design: Retrospective analysis of radiological images., Purpose: To determine the prevalence of lumbosacral transition vertebra (LSTV) and to study its significance with respect to clinically significant spinal symptoms, disc degeneration and herniation., Overview of Literature: LSTV is the most common congenital anomaly of the lumbosacral spine. The prevalence has been debated to vary between 7% and 30%, and its relationship to back pain, disc degeneration and herniation has also not been established., Methods: The study involved examining the radiological images of 3 groups of patients. Group A consisted of kidney urinary bladder (KUB) X-rays of patients attending urology outpatient clinic. Group B consisted of X-rays with or without magnetic resonance images (MRIs) of patients at-tending a spine outpatient clinic, and group C consisted of X-rays and MRI of patients who had undergone surgery for lumbar disc herniation. One thousand patients meeting the inclusion criteria were selected to be in each group. LSTV was classified by Castellvi's classification and disc degeneration was assessed by Pfirrmann's grading on MRI scans., Results: The prevalence of LSTV among urology outpatients, spine outpatients and discectomy patients was 8.1%, 14%, and 16.9% respectively. LSTV patients showed a higher Pfirrmann's grade of degeneration of the last mobile disc. Results were found to be significant statistically., Conclusions: The prevalence of LSTV in spinal outpatients and discectomy patients was significantly higher as compared to those attending the urology outpatient clinic. There was a definite causal relationship between the transitional vertebra and the degeneration of the disc immediately cephalad to it.

Introduction: A series of 12 patients in our centre following single level instrumented posterior lumbar interbody fusion at L4-L5 developed unexplainable motor weakness in the proximal lumbar nerve roots (L2, L3) and numbness of the whole limb, a clinical picture resembling lumbar plexopathy. Even though lumbar plexopathy has been reported following gynaecological procedures and in transpsoas interbody fusion surgeries, there is no literature reporting this complication following conventional instrumented posterior lumbar interbody fusions., Study Design: Retrospective observational study., Objective: To find the possible mechanism of development of lumbar plexopathy in patients who underwent posterior lumbar interbody fusion surgeries in our centre., Material and Methods: We analyzed retrospectively the medical records, electrophysiological reports of the patients, literatures on the anatomy of lumbar plexus and other literature reporting similar complications. We also dissected lumbar plexus of three cadavers and simulated surgical technique on them to find the mechanism of development of this unusual complication., Results: We found injury to lumbar plexus that probably occurred intraoperatively with Hohmann's retractor that was used for retraction of the paraspinal muscles. This theory was favoured by many clinical factors and further confirmed by cadaveric dissections., Conclusion: We conclude that surgical technique with improper use of Hohmann's retractor causes traction and compression injury to the lumbar plexus resulting in this complication. We propose proper technique of insertion of Hohmann's retractor and also recommend use of modified Hohmann's retractor with shorter tips for spinal procedures to prevent such complication.

Gorham's disease is a rare disorder characterized by clinical and radiological disappearance of bone by proliferation of non-neoplastic vascular tissue. The disease was first reported by Jackson in 1838 in a boneless arm. The disease was then described in detail in 1955 by Gorham and Stout. Since then, about 200 cases have been reported in the literature, with only about 28 cases involving the spine. We report 2 cases of Gorham's disease involving the spine and review related literature to gain more understanding about this rare disease.

Spinal hydatid cyst is a rare occurrence in non endemic countries. We present a case of recurrent lumbar hydatid disease in a 21-year-old male who following initial treatment had a good functional outcome and healing for 8 years, following which he came back with complaints of low back ache and neurological deficit. Patient underwent a second surgery with global debridement of L3-L5 vertebrae followed by medical management for two years. He had a good surgical outcome with recovery from the neurological deficit. Patient has returned to his routine activities and is being reviewed every year; there is no evidence of recurrence in the past 3 years. To the best of our knowledge recurrence after 8 years of initial treatment, followed by good clinical and radiological outcome for 3 years after surgery and treatment of the recurrence has not been reported in literature.

Chondrosarcomas are malignant cartilage forming tumours. They form the second most common primary malignant tumour involving the vertebral axis. We present a rare presentation of a secondary chondrosarcoma from the spinous process of lumbar vertebra and discussed its management. The main emphasis is on the rare presentation and the need for awareness and suspicion of the pathology.

Exostosis of the rib with neural foraminal extension as a cause of spinal cord compression and scoliosis has to the best of our knowledge not been reported. We describe a young male with hereditary multiple exostosis who presented with a spastic gait, lower limb weakness and a deformity of the upper back. Radiographic imaging revealed a lesion arising from the left second rib which was encroaching the spinal canal and a scoliotic deformity of the upper thoracic spine. Through a single T shaped posterior approach he underwent a decompressive laminectomy of T1 and T2 vertebra and excision of the lesion. The diagnosis of osteochondroma was confirmed by histopathological studies. He was followed up at one year when his neurological condition had returned to normal however the scoliosis had increased.

Study Design: Retrospective clinical series., Purpose: To assess whether titanium cages are an effective alternative to tricortical iliac crest bone graft for anterior column reconstruction in patients with active pyogenic and tuberculous spondylodiscitis., Overview of Literature: The use of metal cages for anterior column reconstruction in patients with active spinal infections, though described, is not without controversy., Methods: Seventy patients with either tuberculous or pyogenic vertebral osteomyelitis underwent a single staged anterior debridement, reconstruction of the anterior column with titanium mesh cage and adjuvant posterior instrumentation. The lumbar spine was the predominant level of involvement. Medical co-morbidities were seen in 18 (25.7%) patients. A significant neurological deficit was seen in 32 (45.7%) patients. At follow up patients were assessed for healing of disease, bony fuson, and clinical outcome was assessed using Macnab's criteria., Results: Final follow up was done on 64 (91.4%) patients at a mean average of 25 months (range, 12 to 110 months). Pathologic organisms could be identified in 42 (60%) patients. Forty two (60%) patients had histopathological findings consistent with tuberculosis. Thirty of 32 (93.7%) patients showed neurological recovery. The surgical wound healed uneventfully in 67 (95.7%) patients. Bony fusion was seen in 60 (93.7%) patients. At final follow up healing of infection was seen in all patients. As per Macnab's criteria 61 (95.3%) patients reported a good to excellent outcome., Conclusions: Inspite of the theoretical risks, titanium cages are a suitable alternative to autologous tricortical iliac crest bone graft in patients with active spinal infections.

Study Design: Retrospective case series., Objective: To report the clinical features, diagnostic dilemmas and management options of 11 immunologically normal patients with salmonella spondylodiscitis., Summary of Background Data: Majority of existing data on salmonella spondylodiscitis in the immunologically normal patient is from anecdotal case report., Methods: From 1995 to 2008, 11 patients with salmonella spondylodiscitis proven by positive culture, biopsy, and Widal test were included. One patient died, and the average follow-up of the remaining 10 patients was 36 months (12-122 months). Five (50%) patients had a documented history of typhoid fever. Intravenous antibiotics for 2 weeks and oral antibiotics for at least 10 weeks were given to all patients. Indications for surgical intervention were unrelenting pain and osseous instability. Clinical outcome was evaluated according to Macnab criteria., Results: Salmonella typhi was cultured in 4 and S. Paratyphi in 5 patients. No organism was identified in 2 patients, on whom the diagnosis was performed by a characteristic history, high Widal titers, and a positive biopsy. Widal titers were positive for all patients (Average + 1360). Five patients were managed with antibiotics only, 1 with surgical debridement and uninstrumented fusion and 4 with single-stage debridement, anterior fusion, and posterior instrumentation. Healing of disease with a good to excellent outcome was seen in all patients., Conclusion: Salmonella and tuberculous spondylitis must be differentiated as they both have similar epidemiological and clinicoradiologic presentations. Prodromal gastrointestinal symptoms are usually not present. The diagnosis rests largely on the recovery of the organism by appropriate culture techniques. However, when this is not apparent the Widal test, in the setting of a suggestive history and radiograph, may be used as a diagnosis tool. Though antibiotics are the mainstay of treatment, surgical debridement with the use of instrumentation may be indicated in selected patients.

Objective: Posterior spinal surgical approach to achieve a retropleural/ retroperitoneal corpectomy with circumferential spinal cord decompression following subtotal vertebrectomy, posterior instrumentation and interbody spacer placement under compression as well as kyphosis correction with spinal column shortening., Indications: Infective, traumatic or neoplastic lesions of the vertebral body that lead to vertebral body destruction, instability and neurologic deficit. Need for immediate postoperative loading stability to permit ambulation and rehabilitation., Contraindications: Multiple contiguous vertebral disease. Instances where the graft bed preparation and stable interbody spacer placement may be suboptimal due to the limited access offered by this approach., Surgical Technique: Posterior midline exposure two to three levels above and below lesion, dissection at level of lesion extended bilaterally exposing transverse processes, costotransverse articulations and medial 5-8 cm of ribs. Placement of pedicle screws at proximal and distal levels; in case of osteoporotic bone augment screws with cement. Bilateral costotransversectomy at one or more levels to drain prevertebral abscess and expose diseased vertebral bodies. After temporary stabilization, laminectomy and corpectomy are carried out from both sides to permit circumferential decompression. A temporary rod is placed on the contralateral side in the position of deformity to prevent any inadvertent translatory movements during the subsequent surgical step. After completion of the procedure an appropriately contoured rod is placed. The interbody spacer is positioned. Kyphosis correction by spinal column shortening and compression along the posterior implant is performed., Postoperative Management: By day 3 ambulation and rehabilitation are initiated., Results: 22 patients were operated in the last 8 years with tuberculosis (18 patients - twelve paraplegics), osteoporotic fractures (two patients), congenital kyphosis and Ewing's sarcoma (one patient each). All patients were followed up at 3, 6, 9, and 12 months and then annually. At each followup, clinical, hematologic and radiologic parameters were assessed. All interbody grafts and cages incorporated without significant loss of correction. Ten of twelve tuberculous paraplegics recovered. No patient had postoperative infection, interbody spacer- or implant-related complications.

Introduction: Neglected femoral diaphyseal fractures are not uncommon in developing nations however there is a paucity of literature in this regard. Due to lack of effective traction, reduction or immobilisation these fractures are invariably associated with shortening and adjacent joint stiffness, presenting a challenging problem to the treating surgeon. The socioeconomic constraints in our society which result in patients seeking non-medical forms of treatment in the first place also warrant the need for an economically viable, simple effective form of treatment which can be carried out in a less advanced setup, gives reliable outcomes and allows early return to work., Methods: Eleven patients with neglected or late presenting femoral diaphyseal fractures were considered for the study. All patients underwent open intramedullary nailing, bone grafting and manipulation of the knee under anaesthesia. Iliac crest graft was harvested when local callus did not suffice. All patients received a supervised regimen of physiotherapy. Patients were followed up clinically and with plain radiographs at 6 weeks and 3 months to assess union and at monthly intervals thereafter., Results: The mean patient age was 28.8 years (15-48). The mean delay in presentation was 14 weeks (3-32 weeks). The mean shortening was 3.8 cm with four fractures showing signs of malunion. Five patients were given preoperative traction and bone resection was performed in only one patient. The mean hospital stay was 11 days (5-25 days). One patient was lost to follow up, of the remaining 10 patients all united at a mean of 11.9 weeks with 7 patients regaining full range of motion. The mean knee range of motion was 142.5 degrees . There were no wound related or neurological complications. One patient had a patellar tendon rupture which was repaired and another required dynamisation and bone marrow injection for delayed union., Conclusion: We conclude that the treatment of neglected femoral diaphyseal fractures with open intramedullary nailing and bone grafting followed by manipulation of the knee with preoperative traction in selected cases is a satisfactory method of treatment showing reliable bony union however knee mobilisation should be undertaken with caution.

We describe an adult patient with traumatic, nonunion of ulna sustained at 11 years of age who presented with wrist deformity. The possible pathogenesis, differential diagnoses and its successful management are described. A 23-year- old right hand dominant male presented with a progressive wrist deformity of his right upper limb. At 11 years of age, he sustained an isolated open fracture of the right forearm. He had nonoperative treatment. He had 60 degrees of ulnar deviation at wrist. He had no pain in the wrist or elbow. He was able to do all activities using his right upper limb. Radiograph revealed a nonunion of ulna in mid-shaft. The radius was bowed. Radiographs at the time of injury revealed a displaced both bones forearm fracture in mid-shaft. He underwent open reduction, internal fixation of ulna with bone grafting and a corrective osteotomy of the radius. The contracted Extensor carpi ulnaris was Z lengthened. Seven months postoperative, both the nonunion of ulna and radius osteotomy were consolidated. The wrist had no deformity. He had returned to preoperative activity level. Though nonunion is rare in pediatric forearm fractures, asymmetric bone and soft tissue growth can lead to deformities even in the absence of physeal injury. In addition to the standard treatment of nonunion, maintenance of the relative lengths of radius and ulna is essential, to obtain optimum function.
