ELONGATION, COMPRESSION AND SHORTENING APPARATUS FOR TREATING HUMAN AND ANIMAL TUBULAR BONE FRACTURES WITH SHORT DISTAL FRAGMENT Russian patent published in 2013 - IPC A61B17/72 A61B17/68 A61B17/74 A61B17/76 A61B17/78 

FIELD: medicine.

SUBSTANCE: invention refers to medicine. An apparatus for treating human and animal tubular bone fractures with a short and other distal fragment for compression, shortening and elongation of the injured segment represents a Kuncher nail with a threaded proximal end canal, also used as a case of the apparatus, while the other end is bored. The distal end walls have 4 petal windows, while a case opening comprises a steel rod pivotally rotating via the thread and connected with a cam whereto two pairs of petals arranged in the canal of the case distal end are movably attached. A collar crosswise knurled on an external surface for slots of an axle rod introduced in the cross direction through trochanter knots and eyes of the fixator fixed on the collar and used for fracture compression and elongation is screwed on the threaded proximal end of the steel rod projecting from the case opening.

EFFECT: invention provides gripping the distal fragment of any length to immobilise and compress it with the proximal fragment with avoiding extra immobilisation in the form of plaster bandages.
