A Novel surgical apparatus and method of use in osteoplasty and other methods of injecting materials into a subject for medical purposes. The present invention particularly relates to the surgical treatment of traumatic, pathogenic, or osteoporotic bone conditions of the human and other animal body systems and more particularly, to a novel apparatus and method for injection of a material into a lesion of a vertebral body or other bony structure.

A mechanical bone tamping device for osteoporotic repair include a pair of arms mounted on a spreading mechanism such as a screw jack. The mechanism is introduced into a small hole in a vertebra through a cannula, and is then operated to spread the arms apart, forming a cavity which may be filled with cement to fortify the vertebra.

Controlling the transformation of the microstructure of shape memory material implants. A surgeon can use the inventive energy delivery device to control the rate of implant shape change, the extent of implant shape change, as well as the force exerted on the surrounding tissue. The invention allows for the fine control of force when fixating osteoporotic bone and rate of bone transport. This system models or measures the heating profile of the implant and provides the surgeon a method to control the extent of microstructure phase transformation so that the rate, force or extent of tissue movement can be controlled individually or together.

The present invention provides a novel process for producing a calcium phosphate cement or filler which hardens in a temperature dependent fashion in association with an endothermic reaction. In the reaction a limited amount of water is mixed with dry calcium phosphate precursors to produce a hydrated precursor paste. Hardening of the paste occurs rapidly at body temperature and is accompanied by the conversion of one or more of the reactants to poorly crystalline apatitic calcium phosphate. The hardened cements, fillers, growth matrices, orthopedic and delivery devices of the invention are rapidly resorbable and stimulate hard tissue growth and healing. A composite material is provided including a strongly bioresorbable, poorly crystalline apatitic calcium phosphate composite and a supplementary material. The supplementary material is in intimate contact with the hydroxyapatite material in an amount effective to impart a selected characteristic to the composite. The supplemental material may be biocompatible, bioresorbable or non-resorbable. A method for treating a bone defect also is provided by identifying a bone site suitable for receiving an implant, and introducing a strongly resorbable, poorly crystalline apatitic calcium phosphate at the implant site, whereby bone is formed at the implant site. The implant site may be a variety of sites, such as a tooth socket, non-union bone, bone prosthesis, an osteoporotic bone, an intervertebral space, an alveolar ridge or a bone fracture.

The present invention relates to the design and composition of a depot implant for optimal delivery of growth factors to treat osteoporotic bone, in that such depot implant is constructed to be in a cylinder (rod) or sphere shape and have a natural or synthetic polymer scaffold with or without impregnated calcium phosphate particles. The density of the depot is higher than a typical BMP sponge carrier to facilitate it's implantation and slower release of the growth factor. The scaffold is such that it has adequate porosity and pore size to facilitate growth factor seeding and diffusion throughout the whole of the bone structure resulting in increased bone mineral density in the osteoporotic bone. In addition, the shape of the depot implant allows for delivery through a cannula or large bore needle.

A compression wire is partially threaded and has a trocar insertion point for insertion into a bone segment to be stabilized with respect to a second bone segment. A button mates with the wire and is crimped into position on the wire to cause compression and stabilization between the bone segments. A cannulated instrument is used to grasp and apply tension to the wire at a given torque, and further to crimp the button to maintain tension on the wire in a location suitable for later removal. In a second embodiment for osteoporotic bone the wire further includes an internally threaded screw or helix which is implanted into the bone segment to mate with the threads of the wire. The invention further relates to the method of bone stabilization where the threaded wire is implanted into the distil end of a bone segment in ante grade or retro grade and also in a sub-cutaneous or percutaneous fashion and extending through an adjacent bone segment. An end of the wire protrudes from the second bone segment and end receives a button slid onto the wire and crimped into the desired tension. The end of the wire assembly may be left proud for later removal, or countersunk in the bone so as not to protrude.

The invention relates to a device for fixing screws in osteoporotic bones, formed by biocompatible fixing elements and an instrument for placing same. The instrument consists of two parts, a male part (A) and a female part (B), which can perform a relative linear sliding movement. The caudal end of each part has a pivoting jaw (Pa, Pb) forming an inverted U therebetween. The biocompatible element is placed in the jaw of the male part, which element will be traversed by a screw inserted through interchangeable guides (g) placed in the other jaw, acting as a locking and fixing nut for said screw. Both parts have a handle (m) to allow moving the jaws closer together. The opening of the device, restricted by a closure (C), is achieved by the action of a compression spring (R), upon releasing, by the action of the thumb, the catch inserted in the upper face, cut in a saw-toothed manner, of part A.

The invention discloses a big-data-based bone quality assessment expert system and a prediction model establishment method. The system is composed of a server, in which a prediction model module, a data acquisition module and a bone expert module are arranged. A database and an intelligent terminal are connected on the server. The database stores user identity data, characteristic data of historical patients with osteoporosis and fractures, and detection data of to-be-predicted patients. The prediction model module establishes an osteoporosis fracture prediction model; and the data acquisitionmodule is used for acquiring prediction requests and detection data of to-be-predicted patients. The osteoporosis fracture prediction model obtains an osteoporosis fracture prediction level based onthe detection data; and the bone expert module outputs prevention advice to each to-be-predicted patient. The big-data-based bone quality assessment expert system has the following beneficial effects:the fracture prediction of the osteoporosis patient is realized; the operation is convenient without queuing up; the system can be operated at any time at any place; and intelligent and convenient effects are realized.

Gel methacrylate anhydride monomers are weighed to be dissolved in a PBS solution, and the dissolved methacrylate anhydride gelatin monomers are oscillated and dissolved at 37-50 DEG C in the dark; a lithium phenyl-2,4,6-trimethylbenzoylphosphonate blue light initiator is weighed to be mixed with the prepared GelMA solution at room temperature in the dark, and the solution is filtered into a sterile centrifuge tube with a sterile filter;and the related polypeptides or Abaloparatide is added to the sterile centrifuge tube containing the solution, and then the mixed solution is irradiated with a blue light source and cured into the hydrogel of any shapes. Effective entrapment and release of the Abaloparatide and PTH1-34 drugs are conducted and a cumulative release rate reaches approximately 86% on the 12th day. The hydrogel is also applied in cavity locally filled stent materials or applied for repairing and filling bone defects caused by osteoporotic fractures.
