Description
| - Angularly stable plates have been used in medical and veterinary practice for the treatment of unstable fractures for several years. The principle is based on the fixation of a screw in the plate by means of the screw thread. The thread on the screw head must have the same gradient as the thread on the shank; often the thread on the screw head is finer and has multiple starts. In the operating procedure, locking bone screws in the angularly stable plate are manually tightened using a torque clutch with torque 1.5 Nm. Even if this procedure is complied with, when extracting the titanium alloy implant it is difficult (and sometimes impossible) to loosen some locking bone screws from the locking holes in the angularly stable plate. The results of the experiments led to the following recommendations: the torque should be reduced from 1.5 Nm to a lower value; conical (self-holding) screwdrivers should be used when inserting screws and cylindrical (non-self-holding) screwdrivers should be used for extracting screws; instead of the internal hexagon, the screw head should use the TORX system, which gives better torque transfer even when the screwdriver is not fully inserted into the aperture.
