Metallosis with spinal implant loosening after spinal instrumentation: A case report.

Background: Spinal metallosis is a rare complication following spinal instrumentation whereby an inflammatory response to the metal implants results in the development of granulomatous tissue.

Case Summary: We describe the case of a 78-year-old woman who had recurrence of back pain 5 years after lumbar spine posterior decompression and instrumented fusion. Lumbar spine radiographs showed hardware loosening and magnetic resonance imaging showed adjacent segment disease.

Multifocal tuberculous osteomyelitis mimicking widespread bony metastases: review of literature and case report.

Introduction: Mycobacterium tuberculosis infections remain a significant cause of morbidity and mortality worldwide. Extrapulmonary infections are less common, and skeletal tuberculosis accounts for about 5-20% of all cases. Skeletal tuberculosis cases often pose diagnostic challenges due to its insidious onset, non-specific clinical presentation and radiographic findings similar to other diseases.

Mycoplasma hominis Lumbar Wound Infection After Posterior Decompression and Instrumented Fusion: A Case Report.

Case: A 63-year-old man underwent L2-S1 decompression and fusion for spinal stenosis. He developed urinary retention postoperatively requiring catheterization. He developed fever, purulence, and foot-drop 8 days postoperatively and underwent debridement with implant retention.

Utility of a high-definition 3D digital exoscope for spinal surgery during the COVID-19 pandemic.

The COVID-19 pandemic creates unique challenges in the practice of spinal surgery. We aim to show how the use of a high-definition 3D digital exoscope can help streamline workflows, and protect both patients and healthcare staff.

Accuracy and reliability of spinal navigation: An analysis of over 1000 pedicle screws.

Purpose: To estimate the rate of pedicle screw malpositioning associated with placing pedicle screws using intraoperative computed tomography (CT)-guided spinal navigation.

Methods: We analysed the records of 219 patients who underwent pedicle screw fixation using O-arm-based navigation. Screw placement accuracy was evaluated on intraoperative CT scans acquired after pedicle screw insertion.

Correction to: Cervical pedicle screw instrumentation is more reliable with O-arm-based 3D navigation: analysis of cervical pedicle screw placement accuracy with O-arm-based 3D navigation.

Unfortunately, the second author name of the above-mentioned article was incorrectly published in original publication. The complete correct name is given below: Hamid Rahmatullah Bin Abd Razak. The original article has been corrected.

Cervical pedicle screw instrumentation is more reliable with O-arm-based 3D navigation: analysis of cervical pedicle screw placement accuracy with O-arm-based 3D navigation.

Purpose: Despite proven biomechanical superiority and resultant superior clinical outcomes, pedicle instrumentation in cervical spine is not widely practiced due to technical difficulties, steep learning curve, and possible potential catastrophic complications due to screw misplacement. This study was undertaken with the purpose to evaluate the feasibility, accuracy, and complications of cervical pedicle screw instrumentation solely using O-arm-based 3D navigation technology.

Methods: Prospectively maintained data from a single-surgeon case series were retrospectively analyzed.

Severe acute respiratory syndrome in surgical patients: a diagnostic dilemma.

Background: The diagnosis of severe acute respiratory syndrome (SARS) in surgical patients can potentially be missed based on current World Health Organization (WHO) case definitions.

Method: We report a retrospective case series of 10 surgical inpatients diagnosed with SARS following an outbreak in the surgical wards. Patients were included if they fulfilled the WHO case definition of probable SARS, had an active surgical problem and were admitted to the surgical wards during the outbreak period.
