This prospective study evaluates the effectiveness of transpedicular biopsy carried out under local anesthesia in obtaining diagnostic tissue from vertebral body lesions.

Transpedicular percutaneous biopsy of vertebral body lesions: a series of 71 cases.

Magnetic resonance myelography (MRM) after lumbar discectomy is all too often an unrewarding challenge. A constellation of findings are inevitable, and determining their significance is often difficult. MRM is a noninvasive technique that can provide anatomical information about the subarachnoid space. Until now, there is no study reported in literature showing any clinico-radiological correlation of post operative MRM. The objective of this study was to prospectively evaluate the diagnostic effectiveness of MRM for the demonstration of decompression in operated discectomy patients and its correlation with subjective and objective outcome (pain and SLR) in immediate postoperative period.

This study reviews the presentation, etiology, imaging characteristics and reasons for missed diagnosis of Andersson lesion (AL) and analyzes the surgical results of short segment fixation in the thoracolumbar region. This is a retrospective single center study. Fourteen patients (15 lesions) who were operated for AL were analyzed. The study was designed in two parts. The first part consisted of analysis of clinical and radiological features (MRI and radiographs) to highlight, whether definitive characteristics exist. The second part consisted of analysis of outcome of short segment fixation as measured by VAS, Frankel score, AsQoL index, and union, with assessment of complications. The follow-up was 42.33 ± 19.29 months (13 males and 1 female) with a mean age of 61.13 ± 19.74 years. There was predisposing trauma in five patients. There was a delay in presentation of the patients by 5.86 ± 2.50 months. There was misdiagnosis in all the cases, at primary orthopedic level (ten cases were put on anti-tuberculous treatment due to its MRI resemblance to infection) and all but one case at radiologist level. Radiographs and MRI had characteristic features in all cases, and MRI could detect posterior element affection in 14 lesions as against only 8 posterior lesions detected in radiographs. In all patients, there was a patient's delay and/or physician's delay to arrive at a diagnosis. Spinal fusion was seen in all the cases. Outcome measures of VAS, Frankel score, and AsQoL index showed significant improvement (P < 0.002). No major complications occurred. There is a lack of awareness of AL leading to misdiagnosis. Definite clinico-radiological features do exist in AL and short segment fixation is effective.

Retrospective analysis of 53 patients who underwent single stage simultaneous surgery for tandem spinal stenosis (TSS) at single centre.

Coexisting lumbar and cervical stenosis (tandem spinal stenosis): an infrequent presentation. Retrospective analysis of single-stage surgery (53 cases).

Percutaneous aspiration of abscesses under ultrasonography (USG) and computer tomography (CT) scan has been well described. With recurrence rate reported as high as 66%. The open drainage and percutaneous continuous drainage (PCD) has reduced the recurrence rate. The disadvantage of PCD under CT is radiation hazard and problems of asepsis. Hence a technique of clinically guided percutaneous continuous drainage of the psoas abscess without real-time imaging overcomes these problems. We describe clinically guided PCD of psoas abscess and its outcome.

Anterior cervical corpectomy and fusion (ACCF) is a technically challenging surgery. Use of conventional instruments like high-speed burr and kerrison rongeurs is associated with high complication rates such as increased blood loss and incidental durotomy. Use of ultrasonic bone scalpel (UBS) in cervical corpectomy helps to minimize such adverse events.

Comparative Study on Accuracy of Intra-Operative Computed Tomography-Navigation Based Pedicle Screw Placement With Skin vs Bone Fixed Dynamic Reference Frame in Minimally Invasive Transforaminal Lumbar Interbody Fusion.

Calcified lumbar disc herniations (CLDH) causing calcified ventral stenosis pose a therapeutic challenge to the treating surgeon due to their neural adhesions, location, and hardness.
