Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
94 words
A fracture positioning device comprising a pair of arms each having a distal end and a proximal end; pivot means for pivotally attaching the distal ends of said arms, said pivot means permitting movement of said arms towards one another in a clamping direction and permitting substantial movement relative to one another in a direction transverse to said clamping direction for moving fracture fragments into proper position for fixation; a resilient pad carried generally medially on each of said arms; and a safety element detachably connecting the proximal end of each of said arms.
Claim 2
Dependent Claim
