Isolated Tuberculosis of Spinous Process of C5 Vertebra: A Rare Case Report of Reformation of Destroyed Spinous Process.

Introduction: Tuberculosis of posterior spinal elements or neural arch tuberculosis is a rare clinical entity. We report a patient with isolated tuberculosis of the C5 spinous process and reformation of destroyed spinous process in response to antitubercular therapy (ATT). This is first case report of the kind to the best of our knowledge. Case Report: A young male aged 22 years presented to us with a slow-growing, painful lump for the past 3 months accompanied by a discharging sinus at the back of his neck. Plain radiograph and computed tomography scan showed destruction of the C5 spinous process. Magnetic resonance imaging cervical spine showed presence of abscess in addition to the above finding. The patient underwent incision and drainage of abscess followed by local injection of streptomycin. CB-NAAT (Gene Xpert) and histopathological examination confirmed the diagnosis of tuberculosis. The patient responded to ATT very well. The C5 spinous process which was destroyed by the disease process was seen to have gradually reformed on serial radiographs. Conclusion: Isolated posterior spinal tuberculosis is rare, but it must be thought of as a differential diagnosis in suitable cases. Diseased tissue in tuberculosis has high healing potential in response to medical therapy, thus avoiding the need of radical debridement.

Outcomes of Displaced, Comminuted, Intracapsular Neck Femur Fracture in Young Adults Managed with Three Screw Inverted Triangle Versus Four Screw Diamond Configuration: A Comparative Pilot Study.

Background: Three cannulated cancellous screws (CCS) inverted triangle configuration is considered to be the gold standard for management of displaced intracapsular neck femur (ICNF) fractures in young adults. However, some authors have recommended four CCS in diamond configuration in the presence of comminution. However, there are no comparative studies to assess the superiority of one over the other. Therefore, the aim of the present study was to compare the radiological and functional outcomes of displaced, comminuted, ICNF fracture in young adults managed with three screw inverted triangle versus four screw diamond configuration CCS fixation. Material and Methods: Twenty-three patients (group I) with displaced comminuted ICNF fractures were managed with three CCS fixation in inverted triangle fashion between October 2014 and October 2015 and were followed up for a mean duration of 33.5 months (range 25-38 months). Twenty-five patients (group II) with the same inclusion and exclusion criteria were managed with four CCS in diamond configuration between October 2013 and October 2014 and followed up for a mean duration of 33.3 months (range 25-38 months). Radiological outcomes of these patients were compared in terms of union rates and avascular necrosis, while functional outcome was measured by Harris Hip Score (HHS) at a minimum of 24 months. Results: Nineteen patients of group I and 20 patients of group II were available for final follow-up. Mean union time in group I was 15 weeks (12-24 weeks), while in group II, it was 14 weeks (12-24 weeks). There was total of four (4/19) cases of non-union in group I, while it was two (2/20) cases in group II. One patient (1/19) developed avascular necrosis in group I, while two (2/20) developed the same in group II. In group I, the mean HHS was 87.3 (range 84-94) points, while in group II, mean HHS was 93.5 (range 78-96) points. Conclusion: There is no difference in the clinical and radiological outcomes following three screw inverted triangle or four screw diamond configuration CCS fixation of displaced comminuted ICNF fracture in young adults. Thus, we conclude that both three screw inverted triangle or four screw diamond configuration CCS fixation are effective treatment modalities for fracture neck femur with comminution and in the absence of larger studies and long-term follow-up the superiority of one over the other cannot be recommended.

Clinico-Radio-Histopathological Correlation by C-Arm Image-Guided Biopsy in Spinal Tuberculosis.

BACKGROUND/PURPOSE OF THE STUDY: C-arm-guided biopsy is a safe and effective technique for evaluating TB spine and is useful in planning therapy. The purpose of this study was to find a correlation between clinically and radiologically suspected TB spine and C-arm image-guided biopsy-proven cases and to study the complications encountered. METHODS: After evaluating the clinical, laboratory, X-ray and MRI findings, 92 patients with provisionally diagnosed tubercular spine were subjected to C-arm image-guided biopsy. RESULTS: Among our 92 cases, histopathology was positive in 55 cases (59.78%). Out of these 55 histologically positive cases, CBNAAT was positive in 42 cases and negative in the rest 13 cases. Overall, among the 92 cases, CBNAAT was positive in 51(55.43%) of cases, and out of these, histopathology turned out to be positive in 42 of cases. Out of 41 cases with negative CBNAAT, histopathology was suggestive of tuberculosis in 13. The strength of agreement between CBNAAT and histopathology was statistically significant (p < 0.0001; kappa = 0.511). No complication such as bleeding, nerve/cord injury, infection, injury to aorta or pneumothorax was encountered during and after the C-arm biopsy in any case. CONCLUSION: C-arm image-guided biopsy is reasonably accurate and should be used as a tool for diagnosis of TB spine. We recommend histopathological examination as a key component for the diagnosis of TB spine, as it is precise and consumes relatively shorter time. CBNAAT is more rapid but is not a substitute for histopathology for spine TB diagnosis.

Clinico-Radiological Evaluation of Modified Stoppa Approach in Treatment of Acetabulum Fractures.

Background The aim of our study was to evaluate the efficacy of Modified Stoppa approach for surgical treatment of acetabulum fractures by analyzing clinical and radiological outcomes. Also, we assess intraoperative and postoperative complications of fracture treated by using Modified Stoppa approach. Objectives To evaluate clinical outcomes of Modified Stoppa approach by using Merle d'Aubigne hip score. To evaluate the radiological reduction quality of Modified Stoppa approach by using the criteria of Matta, and to assess complications of Modified Stoppa approach.  Method Thirty-two patients participated in this study (mean age 40 years; range 18-60 years) and the male to female ratio was 4:1, patients who underwent surgical intervention for acetabular fracture by using Modified Stoppa approach from Oct 2017 to April 2019 were included. Out of 32 patients, two were lost in follow up, leaving 30 of 32 patients for clinico-radiological analysis. We classified the fracture pattern according to Judet and Letournel classification based on preoperative X-ray AP view, Judet View, and 3D-CT pelvis. Operative time, blood loss, reduction quality, and perioperative complications were assessed in each patient. Clinical outcomes were assessed by Merle d'Aubigne hip score and radiological outcomes by criteria of Matta.  Results Out of 30 acetabulum fractures in 30 patients, three (10%) were categorized as anterior column fracture, one (3.3%) as transverse with posterior wall, one (3.33%) as T-type, six (20%) as anterior column with posterior hemi-transverse and 19 (63.33%) as both column fractures. In our study, most patients have trauma due to road traffic accident (RTA) in 25 (83.3%) and fall from stairs in three (10%) patients. Timing of surgery after trauma was average 5.83 days (range three to 15 days), Mean surgical time determined to be 214.66 min (range 150-350 min) and mean intraoperative loss 683.33 ml (range 230-1250 ml). Clinical outcomes by Merle d'Aubigne hip score was excellent in 13 (43.33%), good in 15 (50%), fair in two (6.66%) patients whereas poor results in 0 (0%) patient (p=0.001). Quality of reduction by Matta criteria was found to be an anatomical reduction in 26 (86.6%), imperfect reduction in three (10%), and poor reduction in one patient (3.33%) (p<0.001). Radiological grading by Matta criteria was excellent in 24 (80%), good in five (16.66%), and fair in one (3.33%) patient, and no patients met criteria for poor results (p<0.001). In operative complications one patient developed an external iliac vein injury which was repaired by a vascular surgeon, one patient had a superficial infection for which debridement, regular dressing, and IV antibiotics given and resolve in one month, obturator nerve injury in one patient which was resolve in five to six months, lateral femoral cutaneous nerve injury in one patient which resolved within three months and one patient urinary bladder injury which was repaired by a general surgeon.  Conclusion Our experience with Modified Stoppa approach for surgical treatment of acetabulum fracture in 30 patients is excellent and effective for better visualization to anterior column, quadrilateral plate, and up to sacroiliac joint. This approach provides better visibility of the fracture site which allows for good to an excellent reduction of fracture and fixation. Although Stoppa approach is cosmetic surgery in terms of scar size, there is less complication rate than the ilioinguinal approach.

Thoracolumbar fracture dislocation (AO type C injury): A systematic review of surgical reduction techniques.

Spinal injuries constitute about 3% of all injury cases and most of these injuries affect the thoracolumbar region, but thoracolumbar fracture-dislocations are much rarer. Dislocations (AO Type C injuries) of the thoracic and lumbar vertebrae, with or without associated fractures, happen due to very high energy trauma involving simultaneous, multidirectional, distractive and compressive forces across various spinal elements, which results in translational and rotational instability of the spinal column. Various reduction maneuvers have been described for thoracolumbar fracture-dislocations in the literature aiming to provide standardization in surgery for this situation. The aim of this review article is to systematically review the literature till date and describe various reduction maneuvers which help to achieve adequate sagittal and coronal balance as well as vertebral alignment with minimal soft tissue trauma. We searched the PubMed, the Cochrane Library (the most recent issue), Scopus, Cochrane Bone, Joint and Muscle Trauma Group Specialised Register, Web of Science, International Clinical Trials Registry Platform (WHO), ClinicalTrials.gov and Google Scholar databases, besides other sources and general internet search. The strategy used in the search was briefly(''thoracolumbar'' OR ''dorsolumbar'') AND "dislocation" in PubMed. Similar searches were made in the other databases.Reference lists of the relevant papers were also examined and any further relevant studies, which were also included in the review. The initial search revealed 332 papers in Pubmed, out of which 302 were human studies. A similar search on Scopus revealed 528 documents and on WoS revealed 289 papers. Searching the Cochrane library revealed 9 trials, which were already revealed in Pubmed search results. All the references were imported into Endnote and we had 632 references after excluding duplicates and 126 papers were left in endnote after manual title screening and duplicate removal. Finally, 70 relevant papers were selected for consideration based on inclusion criteria, after excluding unrelated papers manually. We have summarised the published literature on the surgical management of thoraco-lumbar fracture dislocations and described the reduction maneuvers used in detail.

Fracture-dislocation of the thoracolumbar spine without neurological deficit: a report of two cases and literature review.

INTRODUCTION: We report two cases of fracture-dislocation of the thoracolumbar spine without neurological deficit and outline the putative mechanisms responsible for the escape of neural tissues from injurious forces and the surgical management strategies for this type of injury. We also review similar cases described in the literature. CASE REPORTS: A 24-year-old female with post-traumatic fracture dislocation at the T10-T11 level without neurological deficit, along with a right femoral shaft fracture, was managed with laminectomy of T10-T11 levels with bilateral facetectomy and transpedicular screws and with an intramedullary interlocking nail for the femur fracture. Another 26-year-old female (post-traumatic fracture dislocation at the T12 - L1 level treated by open reduction and pedicle screw instrumentation elsewhere) presented with implant failure and re-dislocation which was managed with laminectomy of T12- L1 levels, facetectomy and discectomy, and deformity correction, followed by 9 mm × 25 mm bullet cage insertion and fixation using transpedicular screws. Neurological function was preserved postoperatively. Both individuals returned to household activity 6 months postoperatively. DISCUSSION: Fracture-dislocations of the thoracolumbar spine without neurological deficit have been infrequently reported. The mechanism responsible for the preservation of normal neurological function; is either posterior element fractures leading to free-floating laminae or a fracture-separation of the vertebral arch, in which pedicle fractures allow the posterior elements to remain nearly aligned, with preservation of the spinal canal integrity and maintenance of normal spinal cord function. These fracture-dislocations need to be managed carefully to achieve a good outcome.

Removal of intra-operatively broken flexible reamer: An innovative use of jumbo cutter.

Reaming is an important step in long bone nailing and has a low complication rate. We report a case of a flexible reamer that got broken and incarcerated in the femoral canal during reaming in a segmental femur fracture. Routine extraction using guide wire was not possible. The incarcerated reamer was successfully extracted with the help of a jumbo cutter.

Outcomes of Core Decompression with or without Nonvascularized Fibular Grafting in Avascular Necrosis of Femoral Head: Short Term Followup study.

BACKGROUND: Avascular necrosis (AVN) of the femoral head usually occurs in the third to fifth decade. The treatment options depend on the stage of disease varying from nonoperative treatment to surgical procedure including core decompression (CD) with or without nonvascularized or vascularized fibular graft, muscle pedicle bone grafting, osteotomies, and arthroplasty. Finite life of the total hip arthroplasty (THA) prosthesis limits its use in young adults or in middle aged. In this study, we envisage to evaluate the clinicoradiological outcomes of CD and nonvascularized fibular grafting in early stages of AVN femoral head. MATERIALS AND METHODS: Our study is longitudinal observational study including 76 hips (46 patients) in the age group of 18-48 years (mean 30.07 years). Ficat and Arlet staging system was used and only early stages, that is, Stage 1 (n = 36 hips) and Stage 2 (n = 40 hips) were included in the study. The cases with traumatic AVN were excluded. All patients in Stage 1 underwent CD (Group 1) and those in Stage 2 underwent CD and fibular grafting (Group 2). Preoperative Harris Hip Score (HHS), visual analog score (VAS), plain radiographs, and magnetic resonance imaging (MRI) were compared with serial postoperative HHS, VAS, plain radiographs, and MRI taken at different intervals. RESULTS: Average period of followup was 53.5 months (44-63 months). Radiological progression was not seen in 55 hips out of 76 hips (72.3%), whereas 21 hips (27.6%) demonstrated signs of progression and collapse. Failure of surgery was defined as progression of the disease, which was 25% (n = 9) in Group 1and 30% (n = 12) Group 2. Median values of HHS at the end of the followup in Group 1 was 77 and in Group 2 was 71.5 compared to the preoperative HHS of 48 and 62 in Group 1 and 2, respectively. Median values of VAS at the end of the followup in Stage 1 was 0 and in Stage 2 was 2 compared to the preoperative VAS of 6 and 8 in Group 1 and Group 2, respectively. CONCLUSION: CD with or without fibular grafting is effective in preserving the sphericity of the femoral head and to delay the progression of the AVN of femoral head in the early stages, that is, Stage 1 and Stage 2 and aids in the early revascularization of ischemic femoral head and is a useful modality to negate or delay the requirement of THA.
