Abstract: A plurality of modular night splints for treatment of different infant foot deformities. The splints comprise a pair of top plates (36 and 37) with base plates (33)1 or foot plates (30) having rotating wedges (49) adjustment mechanisms to which can be added a back leg assembly (44), with a dynamic modular dorsiflexory splint which is able to correct in multiple planes of adjustment simultaneously. In compound deformity problems the modular splint allows the following simultaneous functions:1. abduction/adduction of the foot to the2. abduction/adduction of the forefoot to the rearfoot,3. varus/valgus relationship of the rearfoot to the4. varus/valgus relationship of the forefoot to the rearfoot,5. dorsiflexion/plantarflexion of the foot and leg, and6. abduction/adduction of foot and leg to cardinal sagittal plane.

Abstract: A plurality of night splints for treatment of different infant foot deformities. The splints comprise a pair of top plates (36a and 37a) with base plates 32 or 33, or foot plates (30 or 30a) having an articulated clutch (67) and clutch socket (68), with a dynamic dorsiflexory splint which is able to correct in multiple planes of adjustment simultaneously. In compound deformity problems the universal night splint allows the following simultaneous functions:1. abduction/adduction of the foot to the leg,2. abduction/adduction of the forefoot to the rearfoot,3. varus/valgus relationship of the rearfoot to the leg,4. varus/valgus relationship of the forefoot to the rearfoot,5. dorsiflexion/plantarflexion of the foot and leg, and6. abduction/adduction of foot and leg to cardinal sagittal plane.

Abstract: A lathe duplicator is constructed by mounting a conventional router on one arm of a member mounted to pivot on a guide rail. A second arm of the pivoting member is adapted to guide on a template to control the position of the router bit with respect to a revolving work stock. The router bit is oriented to rotate approximately normal the axis of rotation of the work stock. By rotating the template at the same rate as the work stock, complex surfaces, for example, gun stocks, can be duplicated. The template may be reversed in its direction of rotation to produce reverse surfaces on the work stock. The device is capable of producing spirals and other complex surface configurations.
