Abstract
A surgical device comprising a plate member (10) for mounting to a bone of a subject. The plate member (10) has a first end, a second end, a first face and a second face. At least one spacer member (20) is adapted to be mountable to at least a portion of the plate member (10) and relatively moveable towards and/or away from its first end (13). The spacer member (20) extends outwardly from the second face of the plate member (10) and is prevented from moving away from the first end (13) by a stop member (28) positioned between the first and second ends of the plate member (10).
Claims29
A surgical device comprising:
- a plate member that is mountable to a bone of a subject, the plate member having a first end, a second end, a first face, a second face, and a stop means between said first end and said second end;
- and
- at least one spacer member mountable to at least a portion of the plate member and relatively moveable towards and/or away from the first end, the at least one spacer member, on mounting, extending outwardly from the second face of the plate member;
- wherein on abutment of the spacer member with the stop means, the spacer member is prevented from undergoing further movement in a direction away from the first end of the plate member.
A surgical device of any one of the preceding claims wherein the plate member and the at least one spacer member are made from a biocompatible material.
A surgical device comprising:
- a plate member that is mountable to a bone of a subject, the plate member having a first end, a second end, a first face and a second face;
- and
- at least one spacer member extending outwardly from the second face of the plate member and positionable between two bone surfaces formed in the bone of the subject;
- wherein the plate member has at least one abutment surface engageable with a fixation device used to affix the plate member to the bone, such that relative movement between the plate member and the bone induces an altered stress within the fixation device, the altered stress within the fixation device being such that further relative movement between the plate member and the bone is substantially prevented or at least reduced.
A method of carrying out an osteotomy on a bone of a patient to align the bone or correct a deformity comprising the steps of:
- (a) forming a saw cut in the bone of a patient;
- (b) causing the cut to be widened on at least one side so as to align or correct the deformity of the bone;
- (c) placing the at least one spacer member of the device of any one of the preceding claims within the widened cut such that the at least one spacer member is in contact with cortical bone on each side of the cut;
- and
- (d) securing the plate member to the bone of the patient with a bone fixation device.
The method according to any one of claims 26 to 29, wherein the saw cut is performed through a tibia of a subject substantially in the medio-lateral plane adjacent to the head of the fibula.
