摘要:
The invention provides a guide for controlling a surgical instrument, that includes a cutting member configured to resect a portion of anatomy and a sheath. The sheath may have a circular connecting portion with an inner diameter substantially the same as the outer diameter of the surgical instrument to receive the surgical instrument. The sheath may also include at least two distally extending arms connected to the circular connecting portion and a ring connected to the distal portion of the at least two distally extending arms. The sheath may also include a distally extending extension connected to the ring. The guide has a superiorly extending guard connected to the distal portion of the extension and a projection member positioned on a superior surface of the guard. The projection member includes a generally circular base and circular platform that has a diameter larger than the generally circular base.

摘要:
The present invention relates to a tibial prosthesis useful in knee replacement surgeries. The prosthesis includes one or more cement introduction ports which may be used to deliver and control delivery of bone cement to a prosthesis-bone interface after the prosthesis has been positioned on a resurfaced area of a tibia bone. The prosthesis is suitable for implantation using arthroscopic as well as open surgical procedures. The prosthesis may be used as a unicondylar implant in either compartment of the knee or in both compartments of the knee.
摘要:
Pro-drug compounds of the formula (I) or (II) and compositions containing them are provided that when administered to humans or other mammals provide an increased duration of active compound in the plasma compared to compounds of corresponding structure in which labile groups are not present. In the above formulae n, P, Q, R1, R2 and R3 are as defined in the specification. The compounds may be used to treat a range of neurological conditions, e.g. epilepsy or pain.

The present invention relates to a method of implanting a prosthesis device in a subject. In one embodiment, this method involves: (i) providing a prosthesis device to be attached to an exposed surface of a bone; (ii) applying bone cement in liquid form to a bone-implant interface region, the bone-implant interface region including a region between the exposed surface of the bone and an outer surface of the prosthesis device; and (iii) contacting the bone cement to the exposed surface of the bone and the outer surface of the prosthesis device under conditions effective to allow the bone cement to cure, thereby resulting in attachment of the prosthesis device to the bone of the subject. The present invention also relates to a kit for implanting a prosthesis device in a subject, a method of performing a joint arthroplasty surgical procedure, and other methods of using bone cement in liquid form.

The instant invention is a route to stereospecific 3-substituted 5-membered ring isomers of Formula (A). The final products are useful as agents in the treatment of epilepsy, faintness attacks, hypokinesia, cranial disorders, neurodegenerative disorders, depression, anxiety, panic, pain, neuropathological disorders, gastrointestinal disorders such as irritable bowel syndrome (IBS), inflammation especially arthritis, sleep disorders, premenstrual syndrome, and hot flashes. The invention provides novel routes to synthesize stereoselectively analogs of gabapentin (Neurontin™) of Formulas (I), (II), (III), and (IV) wherein R is C1-C10 alkyl or C3 -C10 cycloalkyl and pharmaceutically acceptable salts thereof.

摘要:
A method is provided for making an enantiomerically pure compound of the formula: in which R and R′ represent C1-C10 alkyl, C2-C10 alkenyl or C3-C10 cycloalkyl and the wedges signify (S)- or (R)-stereochemistry, the substituents in compound (II) being trans. Conjugate addition is carried out between an organometallic nucleophile that provides a group R as defined above and (R)-4-acetoxycyclopent-2-en-1-one, (S)-4-acetoxycyclopent-2-en-1-one or a similar compound in which acetoxy is replaced by another leaving group to give, e.g. in the case of the acetoxy compound, a trans 3,4-disubstituted addition product of formula III or IV;
摘要:
The present invention relates to a femoral prosthesis that includes a cement introduction port which may be used to facilitate delivery or introduction of bone cement into the prosthesis/bone interface after the prosthesis component has been placed on a resurfaced femur bone. The femoral prosthesis may have a keel with undercuts which are configured to assist in controlling the flow of bone cement during implantation and to improve stability of the prosthesis following implantation. The femoral prosthesis is suitable for implantation using arthroscopic, as well as open, surgical procedures. The present prostheses may be used as unicondylar implants in either compartment of the knee or in both compartments of the knee.
