Abstract: The invention described includes an osteoendoscopic cylinder for tamponading bleeding along a longitudinal canal surface of an osteocentral canal of a femoral neck so as to allow endoscopic visualization of a segment of osteonecrotic bone within a femoral head. The osteoendoscopic cylinder is of a dimension adapted to receive an endoscope therein and includes an inner visual surface and an outer bony contact surface. An orientation mark along the inner visual surface is of a size and dimension to ensure a first visualization thereof with the endoscope. The first visualization is of an effect to allow spatial orientation of the endoscope within the femoral head. A side opening proximally situated thereabout a proximal handle end is of a size and dimension adapted to mount a vacuum apparatus comprising of a transparent tube.

Abstract: A tissue collection apparatus for initiating bone formation ex vivo. A substantially cylindrical body includes a closed end, an internal surface, an open proximal end and a detachable closure cap for preventing a flow of air at the juncture thereof and the substantially cylindrical body. A first portion is integral with the detachable closure cap for allowing a flow of a collection of bone growth elements substantially having a quantity of platelets, mesenchymal cells, bone cells, blood and tissue cells, collagen and noncollagenous proteins comprising components thereof to flow into the substantially cylindrical body and strike a procoagulant surface of an interpositional admixture element so as to induce aggregation and degranulation of the quantity of platelets. The interpositional element is interposed within the substantially cylindrical body. A second portion integral with the substantially cylindrical body is provided to allow the connection of vacuum means.

Abstract: An osteodwelling catheter is described for partitioning an osteonecrotic segment of bone in patients with osteonecrosis. The osteodwelling catheter includes a first inflatable balloon designed to induce a collection of platelets to aggregate and degranulate so as to induce hemostasis thereabout the inflatable balloon. A second inflatable balloon is provided so as to induce a collection of platelets to aggregate and degranulate and thereby induce hemostasis locally thereabout the inflated balloon. The partitioning realized by the inflatable balloons allows one to deliver a contrast material to the partitioned segment of bone or alternately measure an arterial or venous pressure. The osteodwelling catheter is passed through an endoscope so as to allow one to observe directly where the balloons are to be inflated inside of the femoral neck. Several embodiments of the osteodwelling catheter are described.

Abstract: A syringe assembly is constructed for purposes of processing a sample of adipose tissue taken from a human donor desirous of having adipose tissue implanted orthotopically or heterotopically for either cosmetic and therapeutic and reconstructive purposes. A cylindrical body includes an open proximal end and an open conical distal end adapted to fit a dynamic sealing cap or alternately a needle for injecting said adipose tissue. The cylindrical body remains integral and orthogonal in orientation to a suction tube having an aspiration probe used to collect adipose tissue. The syringe assembly further includes a proximal fitting cap having a portal of entry and a portal of exit for purposes of sealing the proximal open end of the cylinder to facilitate the collection of adipose tissue samples. A plunger is provided having operational means for engaging an inner wall of said cylindrical body and axially displacing blood and adipose tissue collected therein.

Abstract: The invention describes a surgical implant for providing stabilization of an intraosseous circumferential fracture within a femoral neck of a proximal femur. The surgical implant includes a bone barrel and a cortical side plate having at least one screw hole to allow rigid fixation of the implant to the proximal femur. The cortical side plate abuts a lateral cortex of the proximal femur having a lateral portal of entry to ensure the bone barrel remains substantially parallel to an inner bony surface of the lateral portal of entry at all times. The bone barrel ensures a collection of bone growth elements is retained intraosseously. An osteomedullary rod being coaxially aligned with the bone barrel includes an axial threading for securely engaging an internal mating thread of the bone barrel. The axial threading is adapted to allow clockwise axial rotation of the osteomedullary rod to position a compression head thereof in operational contact with an autogenous cancellous osteomedullary bone cylinder.

Abstract: The invention described includes a plunger pin and an osteomedullary cylinder in operational alignment for creating an autogenous cancellous osteomedullary bone cylinder within a femoral neck. The osteomedullary cylinder includes and inner surface and an outer surface in coaxial alignment so as to establish a material width of the osteomedullary cylinder of a shape and a dimension adapted to induce a stable circumferential fracture therewithin the femoral neck. The stable circumferential fracture is of a dimension to allow substantial proximal advancement of the autogenous cancellous osteomedullary bone cylinder within the femoral neck and into the femoral head so as to bone graft in situ and thereby promote bidirectional new bone formation. The autogenous cancellous osteomedullary bone cylinder has an areal moment of inertia computed by the equation ¼&pgr;(C4-c4) wherein C and c are outer and inner radii, respectively, thereof.
