Cumulative radiation exposure and estimated lifetime cancer risk in multiple-injury adult patients undergoing repeated or multiple CTs.
To estimate the cumulative radiation exposure and lifetime attributable risk (LAR) of radiation-induced cancer from computed tomographic (CT) scanning of adult patients with multiple-injury traumas. ⋯ More than half of the multiple-injury trauma patients were classified as low risk cumulative effective dose (≤20 mSv) and almost all patients had a low LAR risk of cancer incidence from CT studies. Patients who were at the highest risk of cancer from CT scans were those aged under 30 years who had multiple or repeated scans, particularly in the trunk.

The effect of different torque wrenches on rotational stiffness in compressive femoral nails: a biomechanical study.
Rotation instability and locking screws failure are common problems. We aimed to determine optimal torque wrench offering maximum rotational stiffness without locking screw failure. ⋯ Rotational stiffness and fracture site compression value produced by 3 Nm torque wrench was not satisfactory. To obtain maximum rotational stiffness and fracture site compression value without locking screw failure, 6 Nm torque wrench in compression nails and 8 Nm torque wrench in novel compression nails should be used.
