A method of stimulating bone regeneration in a discontinuous section of a long bone in a subject requiring same, comprising the step of applying to said discontinuous section of the bone an effective vacuum for an effective length of time. A device for carrying out the method consisting of a sealable tubular-shaped sleeve or cuff that fits snugly and sealably around the bone section to be treated and that can be evacuated via a port that is integral to the sleeve or port.

1. A device for stimulating osteoblastic activity in a discontinuous section of a long bone, the device comprising: a sleeve or cuff configured to enclose a portion of the long bone above and below the discontinuous section, and adapted to enclose a circumference of the long bone above and below the discontinuous section;a sealable port in fluid communication with an interior of the sleeve or cuff, the sealable port adapted to transmit a vacuum pressure to the discontinuous section of the long bone; andwherein the sleeve or cuff is adapted to resist collapse under the vacuum pressure. 2. The device according to claim 1, wherein the discontinuous section of the long bone is at least 2.5 cm. 3. The device according to claim 1, wherein the sleeve or cuff resists collapse under the vacuum pressure by being sufficiently thick. 4. The device according to claim 1, wherein the sleeve or cuff comprises a dimension and curvature fabricated to fit snugly around the discontinuous section of the long bone, and wherein the sleeve or cuff is composed of an evacuatable, sterilizable, flexible, sealable material. 5. The device according to claim 4, wherein the dimension and curvature of the sleeve or cuff is predetermined based on which type of long bone is being treated, and wherein the long bone is selected from a group comprising a femur, a clavicle, ribs, humerus, ulna, and radius, carpal and metacarpal bones and their phalanges, tibia, fibula, and tarsal and metatarsal bones and their phalanges. 6. The device according to claim 1, wherein the sleeve or cuff is a biocompatible metal. 7. The device according to claim 1, wherein the sleeve or cuff is a biocompatible plastic. 8. The device according to claim 1, wherein: an elastic seal comprises a glue; andthe glue has elastic properties to maintain the elastic seal at the discontinuous section of the long bone to resist breakage of the elastic seal if the section of bone above the discontinuous section moves relative to the section of bone below the discontinuous section. 9. The device according to claim 1, wherein the vacuum pressure is monitored by a pressure gauge attached to the sealable port. 10. A system for stimulating new bone formation in a long bone with a discontinuity defect, the system comprising: a sleeve or cuff configured to enclose the long bone above and below the discontinuity defect, and adapted to enclose a circumference of the long bone above and below the discontinuity defect;a sealable port in fluid communication with an interior of the sleeve or cuff; anda vacuum pump fluidly connected to the sealable port for supplying a vacuum pressure to the sealable port and the discontinuity defect. 11. The system according to claim 10, wherein the sealable port extends from the interior of the sleeve or cuff through skin to an exterior of a body, the sealable port adapted to transmit the vacuum pressure to the discontinuity defect in the long bone. 12. The system according to claim 10, wherein the sleeve or cuff is adapted to resist collapse under the vacuum pressure. 13. The system according to claim 10, wherein the sleeve or cuff is composed of an evacuatable, sterilizable, flexible, sealable material. 14. The system according to claim 13, wherein a dimension and curvature of the sleeve or cuff is predetermined based on a type of the long bone, and wherein the type of the long bone is selected from a group comprising a femur, a clavicle, ribs, humerus, ulna, and radius, carpal and metacarpal bones and their phalanges, tibia, fibula, and tarsal and metatarsal bones and their phalanges. 15. The system according to claim 10, wherein the sleeve or cuff is a biocompatible metal. 16. The system according to claim 10, wherein the sleeve or cuff is a biocompatible plastic. 17. The system according to claim 10, further comprising: an elastic seal configured to hermetically glue the sleeve or cuff to the long bone above and below the discontinuity defect; andwherein the elastic seal is configured to resist breakage if the long bone above the discontinuity defect moves relative to the long bone below the discontinuity defect. 18. The system according to claim 10, wherein the vacuum pressure is monitored by a pressure gauge attached to the sealable port.
