The Modified anatomical direct lateral approach (Vitosha approach), a novel approach in hip arthroplasty, preserving the iliofemoral ligament and restoring the joint capsule, providing higher initial joint stability and easier rehabilitation without the need for post-operative patients' dislocation precautions is provided. The fascial incision curves along the posterior aspect of the greater trochanter and ends at its lower border, preventing a split of vastus lateralis muscle. The anterolateral periosteal layer which conjoins the gluteus medius and vastus lateralis muscles is sharply elevated from the greater trochanter. Gluteus medius muscle and the underlying gluteus minimus are split along its fibers and retracted anteriorly. A vertical capsular incision is made anterior to the femoral shaft, starting from the basicervical line and extending proximally along the longitudinal body axis, with the iliofemoral ligament fibers remained intact.

A method for fixating an artificial convex caput femur surface to the pelvic bone of a patient, the method comprising the steps of: exposing the acetabulum surface, creating a hole or recess in the pelvic bone from the acetabulum side of the pelvic bone, providing the artificial convex caput femur, comprising an elongated member to the hip joint, inserting said elongated member in said hole, and performing an action on the acetabulum side of the pelvic bone such that the elongated member is structurally changed on the abdominal side of the pelvic bone or inside the pelvic bone.

The disclosure relates to an iliac crest displacement device comprising: an engagement member for engaging an iliac crest of a subject; and a pulley assembly for causing the engagement member to move the iliac crest inferiorly, thereby displacing the iliac crest relative to a rib cage of the subject.

A method of establishing access to a hip joint is disclosed. Pre-operative images of the hip joint are processed to produce a first three-dimensional model (pelvis) and a second three-dimensional model (femur). Data from the first probe and data from the second probe are collected and processed to produce a third three-dimensional model (pelvis) and a fourth three-dimensional model (femur), respectively. The first and third three-dimensional models are aligned to produce a first aligned model (pelvis), and the second and fourth three-dimensional models are aligned to produce a second aligned model (femur). A target location is determined between the first and second aligned models, and an entry vector cone is determined from the target location. A navigated guide wire is inserted along the entry vector cone to the target location.

Systems and methods for accessing an interior space of a joint such as a hip joint in preparation for arthroscopic surgery are provided. In general, the described techniques utilize a joint access device having a handle and a dilator shaft and/or sheath coupled to a distal end of the handle. The device can be advanced over a guidewire inserted into a joint to a first position and the guidewire can be reversibly locked to the handle. The handle can be associated with an actuator configured to be actuated to cause the dilator shaft and/or sheath to advance distally toward a second position within the joint while simultaneously retracting the guidewire coupled to the handle.

An implantable medical device for implantation in a hip joint is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.

A minimally invasive surgical procedure for replacing a hip joint is provided. A main incision is initiated at a point being a projection of a tip of a greater trochanter and extends proximally about a distance in the range of from 1 cm to 8 cm in line with the femoral axis. An inline capsulotomy is performed, while keeping muscles and posterior capsule intact, to expose the hip joint capsule for accessing the hip joint. The femoral canal is prepared for receipt of a femoral implant. The femoral head is resected and removed out of the acetabulum. A step of acetabular preparation is performed using a retractor comprising two tip rails, each tip rail having a plurality of tines. Related tools, devices, systems and methods are also provided.

According to an aspect of the invention there is provided a joint distractor, including: a stationary portion configured to fix a first body portion on a first side of a body joint, and an extendable portion configured to be urged against a second body portion on a second side of the body joint, and wherein extension of the extendable portion urges the extendable portion onto the second body portion away from the first body portion thereby forming a gap between articulating surfaces of the first and second body portions within the joint.

A system for performing a minimally invasive interventional fusion procedure on a sacroiliac joint of a patient. The system may include a disposable sterile packed implant and kit including access, bone cutting, accessory and extraction instruments.
