4 Claims. (Cl. 128—84)
This invention relates to improvements in sur
tion of the rod 3 that projects upwardly from
gical leg splints of a similar type to that set
forth in my previous application, Ser. No. 720,581,
now Patent No. 2,069,721, but di?ering therefrom

One of the objects of the present invention is
the provision in a splint that has members that
are respectively applied to an uninjured leg and
the injured leg of a patient, of mechanism to per10 'mit rotative adjustment of both of said members
[as Well as relative longitudinal adjustment
spect to said rods in opposition to
the spring 9.
The upper end of the frame 1
arcuate and has secured thereon
strip constituting a stirrup l4 that

thereof.
_
Another object is to provide a splint having
members for connection with the uninjured and
'15 injured legs, having stirrups that are readily detachable from said members.
Other objects and advantages of the invention
appear in the following description.
An illustrative embodiment of the invention is
20 shown in the accompanying drawing, in which:—
Fig. 1 is a front elevation of a structure in
which the invention is embodied, a portion being
broken away; and
Fig. 2 is a top plan view projected from Fig. 1,
25 certain parts being in horizontal section.
The illustrative embodiment of the invention
includes in its structure a cross-head I provided
at the ends thereof with corresponding rods 2
and 3, which rods extend in parallel relation with
30 each other and. at right angles with respect to the
length of the cross-head. The lower ends of said
rods project downwardly ‘from said cross-head
and are threaded to receive corresponding nuts
4, and have mounted thereon between said nuts
35 and the cross-head a beam 5 that extends laterally in one direction. The beam has in one end
portion thereof oppositely disposed arcuate slots
6 through which the lower ends of the rods 2
screws l5.

The. laterally extending end portion of the
beam 5 has adjustably mounted thereon a bracket
l6, there being a series of spaced apertures ll in ‘15
the beam for the reception of a securing bolt 18
that extends through the bracket and one or an
other of said apertures._ The slot I9 in the
bracket through which the beam extends is suf
?ciently large as to permit of limited tilting 20‘
movement upon the axis of the bolt and also the
lower end of said bracket, being closed, prevents
inadvertent disconnection of the bracket from
the beam when the bolt I8 is removed to permit
adjustments therebetween. The upper end of 25
the'bracket has a threaded stud 20 upon which is
adjustably secured a clamp 2| provided with a
tightening screw 22 to secure the clamp against
rotative movement relative to the stud. The
clamp has at its upper end an arcuate extension 30
23 to the sides of which are removably secured
corresponding separable strips 24 that extend in
parallel relation with each other and constitute
a second stirrup. The strips 24 are individually
removable from said extension upon removal of 35
screws 25 by which said strips are secured to the
extension on the outer faces thereof. Each strip
has made therein a series of perforations 26 for
and 3 respectively extend whereby the cross-head
the reception therethrough of a skeletal pin 21
40 is adapted to be adjusted rotatively upon an axis
at right angles thereto relative to the beam.
Upon the end portions of the rods 2 and 3 that
project upwardly from the cross-head is mounted a frame 1 that is slidable thereon longitudinal45 ly with respect to said rods. The frame 1 has a
hook 8 adjacent its upper end that projects laterally from its outermost side and has connection with one end of a retracting spring 9. The
cross-head I also has a projecting hook II] that
50 has connection with the outer end of said spring,
which spring acts to restrain movement of the
frame on said rods in the direction away from the
cross-head. The frame has at its sides corresponding elongated guides H and I2 into which
55 said rods loosely extend respectively. That por-
which is adapted to be inserted transversely with
respect to said stirrup.

In use, the stirrup I4 is placed astride of the
lower extremity of the uninjured leg of the patient
(not shown). The sides of the stirrup are then
preferably encased together with the uninjured
leg by applying a plaster cast in the usual man
ner. The frame I is thus ?rmly held attached
to the uninjured leg. The strips 24 of the other
stirrup are then placed astride of the injured leg
and, if the surgeon elects to apply skeletal treat
ment, a pin preferably of the Steinmann type is
inserted through the perforations 26 in said strips
and the injured leg so as to engage the bone frag-

ment therein. A plaster cast is then applied so as
to encase the strips, the projecting ends of the
pin and the injured leg, in the usual manner.
The bracket I6 is then adjusted upon the beam to
such position as to afford the desired angulation
or spread between the legs of the patient. The.
clamp 2| is then loosened on the stud by turning
said frame, a bracket adjustably secured on said
beam, a clamp rotatively adjustable on said
bracket provided with an extension, and strips
removably secured respectively upon the outer
sides of said extension constituting a second
the screw 22 to permit movement of the clamp to
plicable respectively to uninjured and injured legs
secure the desired rotative adjustment of the leg,
10 after which the screw is tightened so that ad
justment of the leg is secured in that respect.
After the legs have been secured in their re-_
stirrup.
2. In a surgical splint having members ap
of a patient, a frame provided with a stirrup and
having longitudinal parallel guides, a cross-head 10
having parallel rods that extend into said guides
to permit longitudinal adjustment of said frame

parted to the cross-head I and the beam 5 away
from the frame 1 in opposition to the restraint of
the spring 9, and in this manner is applied exten
sion with respect to the injured leg and counter
clamp rotatively adjustable on said bracket, and
strips removably secured in connection with said
bracket constituting a second stirrup.
3. In a surgical splint having members applica
ble respectively to uninjured and injured legs of a 25
patient, a frame provided with a stirrup and hav
ing longitudinal parallel guides, a cross-head hav
ing parallel rods that extend into said guides to
permit longitudinal adjustment of said‘ frame
thereon, a beam connected with said cross-head
of the uninjured leg is readily accomplished by
extension with respect to the uninjured leg.
A valuable feature of the invention is the ad
justments of the supporting members for the
stirrups with respect to their connecting beam
that a?'ords advantageous positioning of the un
30 injured as well as the injured leg.
And another feature of value is that the strips
that form the stirrups are connected with the
frame 1 and extension 23 respectively in such
manner as to admit of their detachment there
from without discomforture to the patient.
I claim:—
1. In a surgical splint having members applica
ble respectively to an uninjured and injured leg of
a patient, a cross-head having parallel rods lo
40 cated respectively at its ends that extend at right
angles thereto, a beam provided with arcuate slots
through which the lower ends of said rods ex
tend and permit relative adjustment of said
cross-head and beam transversely to said rods,
means for securing said beam in its adjusted posi
tions, a frame having guides at its sides into which
the upper end portions of said rods slidably ex
tend, an adjusting nut having threaded relation
with one of said rods located between said cross
head and frame, a retracting spring the ends of
which are connected respectively with said cross
head and frame, a stirrup removably secured to
so as to permit relative adjustment of said cross
head and beam transversely to said rods, means
for securing said beam in its adjusted positions,
means for moving and securing said frame ad
justably on said rods relative to said cross-head,
and a second stirrup having an adjustable con
nection with said beam.

4. A surgical splint applicable to uninjured and
injured legs of a patient, said splint having a
member including a stirrup for attachment to the “ 40
uninjured leg and provided with a laterally ex
tending beam, another member including a stirrup
for attachment to the injured leg and provided
with a supporting bracket therefor, said bracket
having an opening therein, through which said
beam extends, proportioned so as to permit limit
ed tilting movement of said bracket on said beam,
the bottom of said bracket being closed to prevent
inadvertent disconnection of said bracket from
said beam, and means for securing said bracket “59””
adjustably on said beam.
