A flexible drill bit comprising: a proximal shaft portion for connecting to a source of turning; a distal cutting tip portion for boring into a material; and an intermediate shaft portion extending between the proximal shaft portion and the distal cutting tip portion, the intermediate shaft portion being characterized by (i) sufficient longitudinal flexibility so as to permit the flexible drill bit to be passed along a curve, and (ii) sufficient torsional strength to permit the flexible drill bit to bore into the material. Apparatus for drilling a hole in material, the apparatus comprising: an angled drill guide comprising a curved distal section, a less-curved proximal section, and a lumen extending therebetween, wherein the less-curved proximal section comprises a flat extending therealong for reducing the effective diameter of the less-curved proximal section so as to minimize interference between the angled drill guide and the side wall of an access cannula.

A method of treating a hip joint of a human is provided. The method comprises a step of dissecting an area of the pelvic bone, comprising at least one of the following: dissecting an area between peritoneum and the pelvic bone, dissecting an area between the pelvic bone and the surrounding tissue, dissecting an area of the pelvic region, and dissecting an area of the inguinal region, or, the method comprises at least two of the following steps: dissecting an area of the abdominal cavity, penetrating the hip joint capsule, dissecting an area between peritoneum and the pelvic bone, dissecting an area of the pelvic bone which comprises: dissecting an area between the pelvic bone and the surrounding tissue, or dissecting an area of the pelvic region, or dissecting an area of the inguinal region, and removing or penetrating the tissue surrounding the pelvic bone in the area opposite to acetabulum.

An orthopaedic surgical instrument includes a customized patient-specific 5-in-1 cutting block having a plurality of ribs and cutting guide slots extending between each rib. A bone-facing surface of each rib has a customized patient-specific negative contour configured to receive a portion of a corresponding positive contour of the patient's femur.

The present invention relates generally to implants and tools for the fixation or fusion of joints or bone segments. These tools include tissue dilators and protectors. Other tools include broaches used to shape bores in bone. The tools can also include a system for removing an implant from bone. Implants can include assemblies of one or more implant structures that make possible the achievement of diverse interventions involving the fusion and/or stabilization of lumbar and sacral vertebra in a non-invasive manner, with minimal incision, and without the necessitating the removing the intervertebral disc. Implants for fusing both sacroiliac joints of a patient include a long implant that extends across both sacroiliac joints.

Provided herein are methods and compositions for treating bone osteonecrosis comprising: at least one of a Gelatin tyramine (GT), a gelatin-heparin tyramine (GHT), a gelatin methacryloyl (GelMa), a gelatin acryloyl (GelAC), collagen, or a hydrogel-forming peptide that can be formed ex vivo or in situ for the treatment of bone osteonecrosis; at least one bone growth promoting agent or a macrophage depletion reagent; and optionally one or more pharmaceutically acceptable carriers.

A musculoskeletal stabilization system adapted to stabilize spine and SI joint structures. The musculoskeletal stabilization system includes a spine structure stabilization sub-system and a pelvic structure stabilization sub-system. The pelvic structure stabilization sub-system comprising two multi-function prostheses that are adapted to be delivered to and inserted into SI joints of a subject via a posterior trajectory. The multi-function joint prostheses are further adapted to stabilize respective SI joints and cooperate with the spine stabilization sub-system to also stabilize the subject's spine jointly.

The present invention relates generally to implants used in medical procedures such as bone fixation or fusion. More specifically, this application relates to fenestrated implants used in bone fixation or fusion.

A cartridge assembly to couple an electrosurgical device to treat tissue with an electro surgical unit includes a cartridge member to operate with a power delivery apparatus of the electro surgical unit and a fluid delivery apparatus of the electro surgical unit. An electrosurgical unit includes a power delivery apparatus and a fluid delivery apparatus arranged to operate with a cartridge member to be located in a cartridge receptacle of the electrosurgical unit. An electrosurgical device includes a first electrode spaced alongside the second electrode, with each electrode having a blade shaped member. Each blade shaped member has opposing sides bounded by edges, with the edges having a medial edge and a lateral edge. At least one fluid outlet is adjacent each blade shaped member, and each fluid outlet is in fluid communication with a fluid passage. The device can be operated as either a bipolar device or a monopolar device and includes a switch to inhibit capacitive coupling to one of the electrodes when the other electrode is used in monopolar fashion.
