There are disclosed embodiments of screws for use in orthopedic surgery, particularly in pediatric patients. In some embodiments, inner and outer implantable members are provided, with the outer implantable member threadable on the inner implantable member to provide compression on two or more bone parts. In some embodiments, screw members are provided with a threaded shaft, and the thread continues into the head of the screw member to enable the thread to remain in pediatric bone.

Bone screw

A ratcheting strut comprising: (a) a ratchet box including a through passage; (b) a first tube sized to extend at least partially through the passage, the first tube including ratchet teeth that engage corresponding ratchet teeth of the ratchet box; (c) a second tube mounted to the ratchet box in parallel with the first tube, the second tube operatively coupled to a second fixation adapter; and (d) a threaded rod operatively coupled to a nut and a first fixation adapter, the threaded rod repositionably mounted to the first tube, where the nut is operatively coupled and repositionable with respect to the first tube.

Ratcheting strut

Apparatus and methods for cutting a material, especially with low material speed and high cutting torque. In some embodiments, the apparatus is a hand-held device for quietly cutting through an orthopedic cast with little or no generation of debris. In yet other embodiments, there is a method for automatically advancing material past a shearing surface, such that the shearing action occurs at about the same velocity as the advancement. In yet other embodiments, there is a device for cutting material between a foot and a sharp edge, with the bottom of the foot being under the sharp edge to protect the skin of the patient.

Cast removal system

A prosthetic knee system includes a tibial tray, a non-rotating tibial insert, and a rotating tibial insert. The non-rotating tibial insert and the rotating tibial insert are selectively coupleable to the tibial tray such that a fixed or a mobile orthopaedic prosthesis may be configured. In some embodiments, the tibial tray may be a fixed or mobile tibial tray. Additionally, in some embodiments, the prosthetic knee system may include a femoral component.

Mobile/fixed prosthetic knee systems

Cast remover

A prosthetic knee system includes a tibial tray, a non-rotating tibial insert, and a rotating tibial insert. The non-rotating tibial insert and the rotating tibial insert are selectively couplable to the tibial tray such that a fixed or a mobile orthopaedic prosthesis may be configured. In some embodiments, the tibial tray may be a fixed or mobile tibial tray. Additionally, in some embodiments, the prosthetic knee system may include a femoral component.

A modular long bone prosthesis is provided having a proximal component and a retroversion component. The proximal component is configured at a proximal end to receive a head forming a portion of a joint and is formed at a distal end to mate with additional prosthesis components. The proximal component is formed to simulate an angle inherent in the proximal end of the bone to be replaced and includes an indicator adjacent the distal end to facilitate rotational alignment of the proximal component and additional prosthesis components. The retroversion component includes a proximal end configured to mate with the distal end of the proximal component. The proximal end includes alignment indicia for positioning relative to the indicator on the proximal component. When the indicator is in a first position relative to the alignment indicia the proximal component and the retroversion component establish a first alignment orientation forming an angle simulating the angle inherent in the proximal end of the right long bone of the long bone to be replaced. When the indicator is in a second position relative to the alignment indicia the proximal component and the retroversion component establish a second alignment orientation forming an angle simulating the angle inherent in the proximal end of the left long bone of the long bone to be replaced.
