Torticollis in an 8-year-old child due to Grisel's syndrome - A case report.

Background: Grisel's syndrome is a nontraumatic atlantoaxial subluxation resulting from an ongoing local inflammatory process. Case Description: An 8-year-old male presented to the emergency department with neck pain which was sudden in onset without any history of any significant fall or trauma. On physical examination, the patient had torticollis with a head tilt to the left side and the chin rotated to the right. The CT scan confirmed atlantoaxial subluxation with C1 rotated to the right on the odontoid process without anterior displacement. The patient was managed conservatively with antibiotics, anti-inflammatory agents, and head-halter traction. Conclusion: As Grisel's syndrome can have catastrophic outcomes, early diagnosis and treatment are critical. It must be considered in patients presenting with acute torticollis following an infection or prior surgery.

Current Concepts - Congenital Scoliosis.

BACKGROUND: Congenital scoliosis is one of the 'difficult to treat' scenarios which a spine surgeon has to face. Multiple factors including the age of child at presentation, no definite pattern of deformity and associated anomalies hinder the execution of the ideal treatment plan. All patients of congenital scoliosis need to be investigated in detail. X rays and MRI of spine is usually ordered first. Screening investigations to rule out VACTERL (Visceral, Anorectal, Cardiac, Tracheo-esophageal fistula, Renal and Lung) abnormalities are required. They are cardiac echocardiography and ultrasonography of abdomen and pelvis. CT scan is required to understand the complex deformity and is helpful in surgical planning. METHODS: A comprehensive medical literature review was done to understand the current surgical and non surgical treatment options available. An attempt was made to specifically study limitations and advantages of each procedure. RESULTS: The treatment of congenital scoliosis differs with respect to the age of presentation. In adults with curves more than 50 degrees or spinal imbalance the preferred treatment is osteotomy and correction. In children the goals are different and treatment strategy has to be varied according to the age of patient. A single or two level hemivertebra can easily be treated with hemivertebra excision and short segment fusion. However, more than 3 levels or multiple fused ribs and chest wall abnormalities require a guided growth procedure to prevent thoracic insufficiency syndrome. The goal of management in childhood is to allow guided spine growth till the child reaches 10 - 12 years of age, when a definitive fusion can be done. The current research needs to be directed more at the prevention and understanding the etiology of the disease. Till that time, diagnosing the disease early and treating it before the sequels set in, is of paramount importance. CONCLUSION: The primary aim of treatment of congenital scoliosis is to allow the expansion of chest and abdominal cavity, while keeping the deformity under control. Various methods can be categorized into definitive (hemivertebrectomy) or preventive (guided growth). Casting, Growth rods, Convex Epiphysiodesis are all guided growth measures. The guided growth procedure either 'corrects the deformity' or will have to be converted to a final fusion surgery once the child completes the spinal growth which is preferably done around 10 - 12 years of age. Future directions should aim at genetic counselling and early detection.

Surgical Management in Elderly Patients with Tuberculous Spondylodiscitis: Ten Year Mortality Audit Study.

STUDY DESIGN: Retrospective study. PURPOSE: To evaluate the factors affecting immediate postoperative mortality in elderly patients with tuberculous spondylodiscitis. OVERVIEW OF LITERATURE: Treatment of spinal tuberculosis in the elderly involves consideration of age and co-morbidities, and often leads to an extended conservative management. Surgical intervention in these patients becomes a complex decision. There are no studies on risk factors of mortality in surgically treated elderly with tuberculous spondylodiscitis. METHODS: Two hundred and seventy-six patients with spondylodiscitis were operated between 2005 and 2015. 20 consecutive patients over 70 years of age with and proven tuberculosis who met the inclusion/exclusion criteria were included. Demographic, clinical and radiological profile data with operative details of instrumentation, blood loss, surgical duration, and mortality were noted. There were 20 patients (6 males, 14 females) with a mean age of 73.5 years. The patients were divided into those with mortality (M) and those who survived (non-mortality, NM). Various variables were statistically tested for immediate postoperative medical complications and mortality. RESULTS: There were four mortalities (20%). Age, sex, number of medical co-morbidities, American Society of Anaesthesiologists grade, Frankel grade C or worse, number of vertebrae involved, number of levels fused, blood loss and operative time did not have statistically significant impact on immediate postoperative mortality. Only preoperative immobility duration was statistically higher in the M group (p=0.016) than in the NM group. CONCLUSIONS: Preoperative immobility is associated with immediate postoperative mortality in elderly patients with spinal tuberculosis undergoing surgery. The findings identify preoperative immobility as a risk factor for mortality, which could contribute to a more detailed prognostic discussion between surgeon and patient before surgery.

Short to Mid-Term Term Surgical Outcome Study with Posterior Only Approach on Tuberculous Spondylodiscitis in an Elderly Population.

STUDY DESIGN: Retrospective study. PURPOSE: To study short to mid-term outcome of surgically managed elderly patients of tuberculous spondylodiscitis with posterior only approach in terms of decision making and challenges in treatment, choice of implants and outcomes. OVERVIEW OF LITERATURE: Tuberculous spondylodiscitis in the elderly is increasing due to longer survival rates. It presents with varied clinical manifestations needing surgical management. Management in tuberculous spondylodiscitis has been scarcely reported in the elderly, with a paucity of data on the choice of implants and approach. METHODS: Sixteen patients (five males, 11 females) older than 70-years-of-age culture and/or histopathology proven tuberculous spondylodiscitis were included in the study. All patients were operated using a single posterior approach. Pedicle screw with rods (PS/rods) or spinal loop with sublaminar wires (SL/SLW) were used for fixation. Clinical and surgical details were recorded. Sagittal correction achieved postoperatively and loss of correction at follow-up were noted. RESULTS: The mean age was 73.6 years (range, 70 to 80 years). The mean follow up was 44.5 months (range, 24 to 84 months). The mean immediate postoperative correction of sagittal deformity was 11.3 degrees; this correction was lost by a mean of 3.1 degrees at last follow-up. All 10 patients with deficit showed neurological recovery and all but one of the seven non-walkers were capable of independent ambulation at follow-up. Patients with SL/SLW and PS/rods had similar radiological outcome at final follow up. CONCLUSIONS: Operative management gives satisfactory results in elderly patients with tuberculous spondylodiscitis. The posterior approach provides adequate exposure for decompression and rigid fixation, providing satisfactory clinical and radiological outcomes. SSL/SLW and pedicle screw rod construct both give similar radiological results if used appropriately in patients.

The effect of metal density in thoracic adolescent idiopathic scoliosis.

PURPOSE: Determine impact of metal density on curve correction and costs in thoracic adolescent idiopathic scoliosis (AIS). Ascertain if increased metal density is required for larger or stiffer curves. METHODS: Multicentre retrospective case series of patients with Lenke 1-2 AIS treated with single-stage posterior only surgery using a standardized surgical technique; constructs using >80 % screws with variable metal density. All cases had >2-year follow up. Outcomes measures included coronal and sagittal radiographic outcomes, metal density (number of instrumented pedicles vs total available), fusion length and cost. RESULTS: 106 cases included 94 female. 78 Lenke 1. Mean age 14 years (9-26). Mean main thoracic (MT) Cobb angle 63° corrected to 22° (66 %). No significant correlations were present between metal density and: (a) coronal curve correction rates of the MT (r = 0.13, p = 0.19); (b) lumbar curve frontal correction (r = -0.15, p = 0.12); (c) correction index in MT curve (r = -0.10, p = 0.32); and (d) correction index in lumbar curve (r = 0.11, p = 0.28). Metal density was not correlated with change in thoracic kyphosis (r = 0.22, p = 0.04) or lumbosacral lordosis (r = 0.27, p = 0.01). Longer fusions were associated with greater loss of thoracic kyphosis (r = -0.31, p = 0.003). Groups differing by preoperative curve size and stiffness had comparable corrections with similar metal density. The pedicle screw cost represented 21-29 % of overall cost of inpatient treatment depending on metal density. CONCLUSIONS: Metal density affects cost but not the coronal and sagittal correction of thoracic AIS. Neither larger nor stiffer curves necessitate high metal density.

Postoperative discitis following single-level lumbar discectomy: Our experience of 17 cases.

BACKGROUND: The established protocols of treatment of postoperative lumbar discitis have not been validated till date. We report a retrospective analysis of a series of patients with discitis following single level lumbar discectomy. We analyzed the outcome of conservative treatment of postoperative discitis with the objective to define when and what surgery was required when the conservative treatment failed. MATERIALS AND METHODS: A total of 17 cases of postoperative discitis treated from 2002 to 2009 were followed up and evaluated clinically, radiologically and by laboratory investigations. All the patients were treated initially conservatively with rest and antibiotic therapy after diagnosis and those who did not respond to conservative treatment of at least 4 weeks were treated surgically. The cases were followed up with serial C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), X-ray, computed tomography (CT) scan and magnetic resonance imaging (MRI) for at least 1 year. RESULTS: The mean followup was 40.38 months (range 12-86 months). Four cases failed to respond to conservative therapy and were treated surgically. In three of these four cases, open debridement, transpedicular fixation and posterolateral fusion was performed, and in the fourth case percutaneous transpedicular fixation was done. In the former group, one case was diagnosed to be tubercular, in another case Staphylococcus aureus was cultured where as the third case culture was sterile. All operated patients showed evidence of interbody fusion at 1 year followup. CONCLUSIONS: Early detection and aggressive treatment are paramount in managing postoperative discitis and the majority do well with conservative treatment. Surgical management in the form of transpedicular fixation and debridement, when required, gives excellent results.

Delayed presentation of cervical facet dislocations.

PURPOSE: To review treatment outcomes of 19 patients with delayed presentation of cervical facet dislocations. METHODS: Records of 17 men and 2 women aged 21 to 63 (mean, 39) years who presented with unilateral (n=14) or bilateral (n=5) cervical facet dislocation after a delay of 7 to 21 (mean, 14) days were reviewed. The most common level of dislocation was C5-C6 (n=9), followed by C4-C5 (n=6), C3- C4 (n=2), and C6-C7 (n=2). The neurological status was graded according to the Frankel classification. One patient (with bilateral facet dislocation) had complete quadriplegia (grade A), 11 had incomplete spinal cord injury (grades C and D), and 7 had nerve root injury. Closed reduction using continuous skull traction for 2 days was attempted. In patients achieving closed reduction, only anterior discectomy and fusion was performed. Those who failed closed reduction underwent posterior partial/complete facetectomy and fixation. If there was traumatic disk prolapse, anterior decompression and fusion was then performed. RESULTS: The mean follow-up was 46 (range, 12- 108) months. 10 of 14 patients with unilateral facet dislocation were reduced with traction and then underwent anterior discectomy and fusion. The remaining 4 patients who failed closed reduction underwent posterior facetectomy and fixation; 3 of them had traumatic disk prolapse and thus also underwent anterior discectomy and fusion with cage and plate. Four of the 5 patients with bilateral facet dislocations failed closed reduction and underwent posterior facetectomy and lateral mass fixation, as well as anterior surgery. The remaining patient achieved reduction after traction and hence underwent only anterior discectomy and fusion. All patients achieved pain relief and sufficient neck movement for normal activities. All 7 patients with nerve root injury improved completely; 9 of the 11 patients with incomplete spinal cord injury improved by one Frankel grade, and the remaining 2 by 2 grades. The patient with complete quadriplegia showed no improvement. CONCLUSION: Preoperative traction is a safe and effective initial treatment for neglected cervical facet dislocation, as it reduces the need for extensive (anterior and posterior) surgery. If closed reduction is successful, anterior discectomy and fusion is the surgery of choice. If not, posterior facetectomy and fusion followed by anterior surgery is preferred.

Wide resection and stabilization of ulnar stump by extensor carpi ulnaris for giant cell tumor of distal ulna: two case reports.

The distal end of ulna is an extremely uncommon site for primary bone tumors in general and giant cell tumor in particular. Wide resection is usually indicated in such cases and at times it may be necessary to remove of a long segment of the distal ulna. Any ulnar resection proximal to the insertion of pronator quadratus can lead to instability in the form of radio-ulnar convergence and dorsal displacement (winging) of the ulnar stump. This can result in diminution of forearm rotation and weakness with grasp. Stabilization of the ulnar stump after resection for a giant cell tumor was described by Kayias & Drosos. We are adding two more cases to the literature. Both patients had excellent functional outcome and there were no instances of recurrence at three years of follow-up.
