Cuff for the relief of tennis elbow and the like

DETAILED DESCRIPTION Proceeding therefore to describe the invention in detail, the cuff is preferably made from a polypropylene sheet of synthetic plastic.
However it will be appreciated that any other suitable plastic can be used and that the finished cuff, due to the configuration thereof is relatively rigid so that the term "semi-rigid" is meant to embrace any mouldable material, which when in its finished shape, has a substantially rigid characteristic.
Dealing first with the preferred embodiment illustrated in FIGS.
1 and 2, the method of manufacture of the cuff 10 is as follows: The patient's forearm (not illustrated) is cast with a plaster of paris bandage after the installation of a separator such as a cotton stockinette separator.
The cast extends from four inches proximal to the olecranon, to approximately four inches distal to the olecranon.
During the casting process, the patient must have the forearm musculature relaxed with the elbow being flexed to approximately 90.
degree.
and the hand pronated.
After the cast application but before same has set, the finger tips of the applicator's hand are pressed in triangular form so as to apply pressure on either side of the radial head and immediately distal to and directly over the muscle belly overlying the radius and this pressure is maintained until the cast has set.
Once set, the stockinette separator is reflected down over the cast and the cast and the separator removed by sliding same distally from the forearm.
Following removal of the cast, one end of the cast is closed and the cast is filled with a plaster of paris mixture or the equivalent.
At this stage a hollow metal pipe is inserted into the plaster mix and the mix is allowed to harden.
Once hardened, the original plaster of paris bandage wrap is removed together with the separator and the resulting hardened cast is smoothed overall.
A U-shape is carved in the cast connecting the three indentations made in the casting procedure and this carving is to a depth approximately the depth of the indentations
