The present disclosure concerns a composition for an implantable pharmaceutical composition prepared from components consisting only of calcium sulfate α-hemihydrate in combination with two antibiotics, vancomycin and gentamicin, for the treatment of infection in bone and soft tissue.

Implantable pharmaceutical composition prepared from components consisting of calcium sulfate alpha-hemihydrate, vancomycin and gentamicin

Disclosed is a device for implantation into a bone void while minimising the potential for an increase in pressure within the bone void.

Device to fill a bone void whilst minimising pressurisation

Disclosed is an invention that provides a method of treating a bone void of a patient through the use of an implantable device whilst minimising the potential for an increase in pressure within the bone void thus avoiding embolization of the void contents into the patient's bloodstream.

Method to introduce an implantable device to fill a bone void whilst minimising pressurisation

A means to prepare bone cement pellets comprising bone cement paste which hardens through hydration a flexible mold mat having pellet cavities on both sides and a scraper for pasting the bone cement paste in to the pellet cavities where the paste is allowed to harden.

Mould mat for producing bone cement pellets

A bone implant composition, the composition comprising calcium sulphate and slowly soluble source of calcium, orthophosphate and hydroxyl ions. The composition may be provided in powder or granulated form.

Calcium phosphate/sulfate-based bone implant composition

A biodegradable material for use in making items usable in surgery and related fields of medicine. The material comprising a bioabsorbable thermoplastic polymer component and a bioactive filler material. In components made of the material particles of the filler material occur embedded within the surface of the components.

Biodegradable material components

A bone graft composition includes beta-tricalcium phosphate and calcium sulphate and slowly soluble sources of calcium ions and hydroxyl ions.

A suture anchor assembly with an anchor and a driver locatable in an axial longitudinal opening in the anchor. A suture is provided extending through the opening and outside of the anchor at its distal end, and passing proximally along longitudinal grooves on the outside of the anchor. A recess is provided in the longitudinal opening of the suture body and a groove formation is provided in the drive part of the driver to locate the suture therein.

Suture anchor and driver

A method of producing surgical grade calcium sulphate suitable for use as resorbable osteoconductive bone void filler material. The method comprising forming an initial calcium sulphate di-hydrate from synthetic constituents; dehydrating the initial calcium sulphate di-hydrate to form calcium sulphate anhydrite; and subsequently rehydrating the calcium sulphate anhydrite and allowing subsequent calcium sulphate di-hydrate to crystallize out.

Method of producing surgical grade calcium sulphate

A process for the production of ammonium nitrate bodies in particulate form wherein an ammonium nitrate/water liquid mixture containing at least 92% and preferably at most 97.5% by weight ammonium nitrate, optionally with a proportion of the ammonium nitrate substituted by alkali- and/or alkaline earth metal nitrate, and a small amount of poly-styrene sulphonate crystal-habit modifier is sprayed as droplets into an atmosphere in which cooling effects crystallization of the ammonium nitrate and which the crystallized particles are dried to remove moisture, wherein the liquid mixture also contains ammonium sulphate, the concentration of poly-styrene sulphonate in the liquid mixture being at least 0.01%, preferably in the range 0.02 to 0.06%, by weight, and the concentration of ammonium sulphate in the liquid mixture being greater than that of the poly-styrene suphonate and at least 0.04%, preferably in the range 0.06 to 0.15%, by weight. Ammonium nitrate bodies, preferably prills, produced by the process may contain less than 0.1% by weight water and be able to absorb not less than 6% of their weight of fuel oil while remaining a pourable particulate material.

Ammonium nitrate bodies and a process for their production

A modular panel system consists of a plurality of panels. Each panel carries at least one and preferably two pivotal connection devices. Each pivotal connection device has thereon a hook-like or latch-like member which can fit into a slot to releasably connect one panel to an adjacent panel. A particular design of double axis hinge is also disclosed, which serves as the pivotal connection device.
