Abstract
A traction splint for a long bone extremity fracture in which the length of the frame of the traction splint and the angle of the ischial pad of the traction splint relative to the frame are adjusted simultaneously. The ischial pad is pivotally connected to the frame and the pivotal movement of the ischial pad relative to the frame is restricted or limited up to 35.degree..
Claims5
A traction splint comprising:
- A. a frame having parallel side members, each of said side members comprising:
- (a) a tube,
- (b) a rod telescopically received by said tube for adjusting the extent of said rod, and
- (c) a releasable locking device receiving said rod and said tube for releasably retaining the adjusted extent of said rod;
- B. an ischial pad disposed generally transversely of said side members, said ischial pad having oppositely directed ends;
- and
- C. pivotal means interconnecting each end of said ischial pad, said pivotal means interconnecting said ends of said ischial pad to said side members, respectively, for angularly positioning said ischial pad relative to said frame, said pivotal mean selectively limiting the angular positioning of said ischial pad relative to said frame,
- D. each of said tubes having one end adjacent said ischial pad, said pivotal means joining the ends of said ischial pad to adjacent ends of said tubes, respectively, for adjusting simultaneously the extent of one or more of said rods and the angle of said ischial pad relative to said frame while at least one of said releasable locking devices enables the extent of one or more of said rods to be adjusted, each of said tubes having an axis and each of said pivotal means comprising:
- (a) a tubular pivotal member attached to one end of said ischial pad, said tubular pivotal member having an axis disposed at right angles to the axis of the tube adjacent said one end of said ischial pad, and
- (b) a tubular member fixed to one end of said tube adjacent said one end of said tubular pivotal member, said tubular member having an axis coextensive with the axis of said tubular pivotal member, said tubular pivotal member and said adjacent tubular member having perimetric confronting ends,
- (c) said tubular pivotal member and said adjacent tubular member at the perimetric confronting ends thereof being formed with interposed ridges and grooves for selectively limiting the angular positioning of the ischial pad relative to said frame.
