Abstract
Abstract An orthopedic traction leg splint assembly is comprised of a forward L-shaped trough-like shell to support the calf, ankle and foot of a patient. A rear trough-like shell supports the patient''s thigh. Both shells may be lined with a thick, resilient pad removably secured by an adhesive. The shells are joined by pairs of hinges including longitudinally pivotally connected slotted hinge bars, which may be adjusted to space the shells longitudinally and position them angularly. Straps removably attached to the rear shell and eyebolts on the forward can be secured to support traction ropes. The assembly can be supported by traction ropes, to insure full support of the splint and patient''s leg.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
162 words
A traction leg splint assembly for a patient comprising a forward trough-like shell shaped to support said patient''s calf and foot; a rear trough-like shell shaped to support said patient''s thigh, both of said shells being open at the top to define free upper edges at opposite sides; thick resilient pads removably cemented in place inside said shells and lining the same to space the patient''s leg from said shells at all points; hinges at opposite sides of said shells joining adjacent ends of said shells, each of said hinges being of a length so as to extend above the top of the free upper edges of the trough-like shells and comprising a pair of crossed, mutually rotatable and slidable hinge bars; attachment means releasably connecting said pair of hinge bars for adjustably positioning said shells with respect to each other both longitudinally and angularly; and a traction rope means connected to said hinge to support said assembly in a balanced position.
Claim 2
Dependent Claim
162 words
A traction leg splint assembly for a patient comprising a forward trough-like shell shaped to support said patient''s calf and foot; a rear trough-like shell shaped to support said patient''s thigh, both of said shells being open at the top to define free upper edges at opposite sides; thick resilient pads removably cemented in place inside said shells and lining the same to space the patient''s leg from said shells at all points; hinges at opposite sides of said shells joining adjacent ends of said shells, each of said hinges being of a length so as to extend above the top of the free upper edges of the trough-like shells and comprising a pair of crossed, mutually rotatable and slidable hinge bars; attachment means releasably connecting said pair of hinge bars for adjustably positioning said shells with respect to each other both longitudinally and angularly; and a traction rope means connected to said hinge to support said assembly in a balanced position.
Claim 3
Dependent Claim
36 words

Claim 4
Dependent Claim
32 words
A traction leg splint assembly as defined in claim 1, further comprising removable, adjustable pairs of straps attached to opposite sides of said rear shell for support by another traction rope means.
Claim 5
Dependent Claim
48 words
A traction leg splint assembly as defined in claim 1, wherein said forward shell has a general L-shaped configuration with a bottom portion for receiving said patient''s calf and ankle, and an upstanding end Portion for receiving said patient''s foot, both of said portions having ventilation holes therein.
Claim 6
Dependent Claim
34 words
A traction leg splint assembly as defined in claim 4, further comprising other attachment means on said end portion for engaging still another traction rope means to support said assembly at said end portion.
Claim 7
Dependent Claim
