Objective: Perform a cadaveric experimental pilot study to measure and compare potential radiation exposure to an orthopedic surgeon from 2 different-generation mini C-arm models during a simulated orthopedic surgery.
Sample: 16 radiation dosimeters.
Methods: Mock surgery setups were constructed with a canine cadaver thoracic limb and 2 different-generation mini C-arm models. Four radiation dosimeters were placed near the mini C-arm to mimic common locations of radiation exposure during image acquisition. One mini C-arm was placed in auto technique mode, and 100 static images were acquired. The dosimeters were replaced, and a 5-minute-long dynamic image was acquired. The same protocols were repeated for the second mini C-arm. The dosimetry badges were then submitted for radiation exposure quantification.
Results: All but 1 dosimeter had radiation exposure levels below the detectable limits of the dosimeter. The dosimeter closest to the primary x-ray beam of 1 mini C-arm during dynamic image acquisition had a reading of 1 mrem.
Clinical Relevance: Intraoperative radiation exposure from the mini C-arm is low, specifically to areas not protected by lead and in close proximity to the primary x-ray beam. That being said, surgeons should always practice the principles of ALARA (ie, as low as reasonably achievable) to minimize radiation exposure in the workplace.

When a surgical needle is lost, the protocol is to explore the surgical field and to obtain a plain radiograph if the needle cannot be located. The size of the needle that can be detected with imaging is debated. Plain-film radiographs, C-arm, and mini C-arm fluoroscopy imaging was obtained of a cadaveric hand with retained needle of varying lengths (suture sizes 4-0 - 10-0).

Objective: This study aimed to compare the accuracy of robotic spine surgery and conventional pedicle screw fixation in lumbar degenerative disease. We evaluated clinical and radiological outcomes to demonstrate the noninferiority of robotic surgery.
Methods: This study employed propensity score matching and included 3 groups: robot-assisted mini-open posterior lumbar interbody fusion (PLIF) (robotic surgery, RS), c-arm guided minimally invasive surgery transforaminal lumbar interbody fusion (C-arm guidance, CG), and freehand open PLIF (free of guidance, FG) (54 patients each).

Background: Mini 'C'-arm machine is an advanced medical imaging device used primarily for intraoperative imaging during surgical, orthopaedic and emergency care procedures. Since the technology is based on ionising radiation, safe usage of Mini 'C'-arm machine is mandatory to protect patients and operating personnel.
Objective: The main objective is to describe the various components related to patients, operator and equipment to ensure safe usage of Mini 'C'-arm machine.
