[edit on Wikidata] The quadriceps femoris (/ˈkwɒdrɪsɛps ˈfɛmərɪs/, also called the quadriceps extensor, quadriceps or quads), is a large muscle group that includes the four prevailing muscles on the front of the thigh. It is the great extensor muscle of the knee, forming a large fleshy mass which covers the front and sides of the femur.
Method and apparatus for reducing femoral fractures
InactiveUS7258692B2Reducing a hip fracturePrevent escapeInternal osteosythesisJoint implantsRight femoral headHip fracture
An improved method and apparatus for reducing a hip fracture utilizing a minimally invasive procedure which does not require incision of the quadriceps. A femoral implant in accordance with the present invention achieves intramedullary fixation as well as fixation into the femoral head to allow for the compression needed for a femoral fracture to heal. To position the femoral implant of the present invention, an incision is made along the greater trochanter. Because the greater trochanter is not circumferentially covered with muscles, the incision can be made and the wound developed through the skin and fascia to expose the greater trochanter, without incising muscle, including, e.g., the quadriceps. After exposing the greater trochanter, novel instruments of the present invention are utilized to prepare a cavity in the femur extending from the greater trochanter into the femoral head and further extending from the greater trochanter into the intramedullary canal of the femur. After preparation of the femoral cavity, a femoral implant in accordance with the present invention is inserted into the aforementioned cavity in the femur. The femoral implant is thereafter secured in the femur, with portions of the implant extending into and being secured within the femoral head and portions of the implant extending into and being secured within the femoral shaft.

Method, apparatus, and system for bracing a knee
InactiveUS7553289B2Enhance proper positioningFunction increaseNon-surgical orthopedic devicesAxial displacementQuadriceps muscle
A knee brace functions to extensionally center and thereby enhance patellar function. The brace comprises an upper bracket assembly, a lower bracket assembly, and certain torsional spring assemblies. The upper and lower bracket assemblies comprise leg-receiving bracket portions and certain axial support structure extending from the bracket portions to bracket junctions. Each spring assembly comprises a torsional spring element and an elastically compressible core element. The torsional spring elements compressibly receive the core elements. The torsional spring elements are actuable for imparting restorative resistance forces, and the core elements function to damp the restorative resistance forces. The damped restorative resistance forces function to safely enhance quadriceps muscle contraction during knee extension. The enhanced quadriceps muscle contraction functions to center the patella during knee extension, and thereby enhance patellar function. The brace may be attached to an anchored leg-covering garment for further restricting axial displacement relative to the leg.

Smart bell
A hand held weight lifting device with a finger grip system attached to a resistance mechanism that is visually located in the middle of the handle and is designed to target the hands, wrist and forearms. The handles may be removed allowing a person to perform all dumbell related exercises. When using a collar, that safely and securely stabilizes the weights in a stationary form, the device can transform from solo or single status, to a dual, unilateral exercise experience. The device can be adjusted from 10″ to 20″ depending on the type of exercise required. The device, coupled with ankle straps and shin pads, provides a person the ability to perform lower body exercises targeting the hamstrings (rear thighs), quadriceps (thighs), lower abs (leg raises) and calfs. In regards to the upper body, the handles provide a comfort grip while performing exercises targeting all major muscles associated with the torso as well as biceps (arms) and trapezius (shoulders). This device is equipped with a resistance bar. When attached to both handles and the handles are squeezed together, it in turn targets the pectoral (chest) muscle.

A device for exercising leg muscles, ligaments, and tendons attendant to movement of a human knee following knee replacement surgery or during rehabilitation following knee injury is provided. The user lies supine on a flat surface and braces the back of his or her upper thigh against the device's leg support bar, so that the user's upper thigh is approximately perpendicular to the user's upper torso. The patient maintains this position and exercises the knee by extending and flexing his or her lower leg. Some embodiments include an elastic band that attaches to the device in a position that limits the degree of leg flexion to within a desired range. Some embodiments include an ankle strap attached to a cord, which may be used to build quadriceps strength through application of resistance, and / or for applying downward pulling force to the lower leg during passive range-of-motion exercising.

My invention pertains to a portable fitness apparatus that allows you to add numerous exercises to your back workout routine with the use of different angles while maintaining lesser points of body contact compared to modern gym back machines. The benefit having lesser points of body contact while using this apparatus is that you burn more calories compared to a modern gym back machine, primarily because you voluntary engage your back muscles as your primary target while involuntary engaging core muscles and quadriceps as your secondary target within the same movement. This apparatus is unique because nothing like this exists in the fitness industry. It is easily assembled, disassembled and light weight so you can take it anywhere. This invention creates a constant tension on your core muscles and quadriceps while working your back muscles, which allow you to burn more calories during your regular exercise movement, and all within the same time frame.
