摘要： An orthopedic screw extractor device including a shaft, an end portion about a first end of the shaft for securing to a handle, and a screw extracting tip about a second end of the shaft opposite the first end. The screw extracting tip further includes a generally frustoconical shape having a side at an angle of about 5 to 15 degrees relative to a longitudinal axis of the screw extracting tip. The screw extracting tip further includes first, second and third screw threads and first, second and third flutes circumferentially spaced about the screw extracting tip and extending across an entire length of the screw extracting tip. Each of the screw threads has a lead of about 0.07 to 0.12 inches, a pitch of about 0.02 to 0.04 inches, a thread angle of about 40 to 50 degrees, and a depth of about 0.01 to 0.02 inches.

摘要： The invention relates to an improved-structure instrument (1) for allowing the alignment of fixing screws (2) to be inserted in transverse holes (3, 13) of nails (4) for long bones, in particular medullary nails, of the type comprising an arched arm (15) having a free distal end (6) connectable to a proximal end (16) of a head (7) of the nail (4) in which the transverse holes (3, 13) are formed, and a proximal handle portion (5), as well as a connection portion (20) between the distal end (6) and the proximal handle portion (5). Advantageously, the connection portion (2) comprises at least one through-hole (23, 33) for receiving a guide tube (10) for a drilling bit, the through-hole (22, 33) having an axis coinciding with the axis of one of the transverse holes (3, 13,) and manually operated quick-locking means (25) are associated with the through-hole (23, 33) so as to lock in a stable position the corresponding tube (10) inserted in the instrument (1).

摘要： The present disclosure relates to an interference screw for creating an interference fit between a bone tunnel and tissue. The screw includes a threaded body having a proximal end, distal end, and thread extending around the threaded body between the proximal and distal ends. A supporting spline extends along a cannulation through the threaded body. The supporting spline is engagable with a delivery device. The screw further includes at least one opening defined by a surface between threads of the threaded body. A ratio of open surface area to closed surface area defines the opening and is selected such that, when torsionally loaded, the screw does not exhibit plastic deformation when inserted into an undersized bone tunnel. The screw further includes a tapered tip extending from the distal end of the threaded body. The tapered tip has a thread extending at least partway around the tapered tip.

摘要： The disclosure provides examples of an open architecture anchor for securing soft tissue to bone, for example, to repair a torn rotor cuff. The anchor includes at least one open helical coil defining a polygonal internal volume and at least one rib disposed within the polygonal internal volume and connected to at least two turns of the at least one open helical coil. The at least one rib is sized to engage a driver and a combination of the at least one rib and the polygonal internal volume is sized to provide an anchor drive torque required to drive the anchor into bone.
