Abstract: Tools and techniques are described that are useful for trauma correction of anterior compression, chance, or burst fractures, particularly where the posterior longitudinal ligament and posterior arch anatomy is still intact. The described tools can be used to reduce fracture and provide additional distraction for ligamentum taxis through a posterior approach that is compatible with both open and minimally invasive methodologies.

Abstract: Devices and methods for bone fixation including a bone fixation system including a bone plate or intervertebral spacer including a plurality of apertures dimensioned to receive bone fasteners and at least one polymeric element capable of transitioning from a solid state to a flowable state. The polymeric element transitions to a flowable state as a result of exposure to ultrasonic vibration.

One or more elastomer receiving recesses are provide in the first end, the second end, or both the first end and the second end. Elastomer material is provided in the one or more elastomer receiving recesses. The elastomer is interlocked with the one or more elastomer receiving recesses and the printed housing creating interlocking joints. The interlocking joints between the elastomer material and the housing permanently attach the elastomeric material to the housing.

Abstract: This disclosure relates generally to mechanical surgical arms having a connector for attaching a surgical tool to the arm across a sterile drape. In various aspects, a drape connector for securing a tool to a surgical arm across a sterile drape includes a flexible collet for receiving a ball of a connection shank of the surgical arm to selectively secure the flexible collet to the surgical arm. The drape connector may also include a lock associated with an inferior end of the flexible collet. The lock may be for adjusting the flexible collet from an unlocked position to a locked position. Further, the drape connector may include a housing for receiving the flexible collet and the lock. The housing defines a window to provide access to the lock to adjust the flexible collet from the unlocked to the locked position.

Abstract: There is disclosed a method of verifying transactions comprising assigning ‘trusted status’ a subset of users, the subset of trusted users defining a centralised root of trust, issuing one or more tokens from the centralised root of trust to users, submitting a transaction involving at least one token for verification by each of the subset of trusted users, determining whether or not a transaction is centrally verified based on whether or not a predetermined proportion of the trusted users have individually verified the transaction or not, and wherein if the transaction is centrally verified the transaction is recorded to a centralised ledger, and wherein if the transaction is not centrally verified, the transaction is not recorded to the centralised ledger. There is also disclosed a system for verifying transactions according to the above method.
