A subretinal implant is advantageous over an epiretinal implant in part because of its simpler design. The light acquisition, processing, and stimulation are all carried out by microphotodiodes mounted onto a single chip, as opposed to the external camera, processing chip, and implanted electrode array associated with an epiretinal implant.

The acetabular notch is a deep [citation needed] notch in the inferior portion of the rim of the acetabulum. [ 1 ] : 1354 It is bridged by the transverse acetabular ligament , converting it into a foramen (through which nerves and vessels (including the acetabular notch of obturator artery [ 1 ] : 1250 ) pass into the hip joint cavity).
Studies on metal-on-metal (MoM) hip resurfacings have identified several factors contributing to early implant failure. Key among these are: Incorrect alignment of the implant stem relative to the femoral neck axis. Notching of the femoral neck during the preparation of the femoral head. Exposure of cancellous bone following implantation. [3]
Orthopedic implant example seen with X-ray. An orthopedic implant is a medical device manufactured to replace a missing joint or bone, or to support a damaged bone. [1] The medical implant is mainly fabricated using stainless steel and titanium alloys for strength and the plastic coating that is done on it acts as an artificial cartilage. [2]
Implant that has been used for fixation of a broken wrist. Closed reduction internal fixation (CRIF) is reduction without any open surgery, followed by internal fixation. It appears to be an acceptable alternative in unstable distressed lateral condylar fractures of the humerus in children, but if fracture displacement after closed reduction exceeds 2 mm, open reduction and internal fixation ...
Kernohan's notch is a cerebral peduncle indentation associated with some forms of transtentorial herniation (uncal herniation). [ 1 ] [ 2 ] It is a secondary condition caused by a primary injury on the opposite hemisphere of the brain. [ 3 ]
End notching works the end of the tube, such as a semicircular concavity to make the base of a tee, or a convex vee to fit into a mitre. Vee-notched tube, bent for assembly of a mitred joint Side notching (also called offset notching ) works the side of a tube with a vee notch for bending, semicircular or vee notches for tee joint.
Retinal detachment is a condition where the retina pulls away from the tissue underneath it. [1] [2] [3] It may start in a small area, but without quick treatment, it can spread across the entire retina, leading to serious vision loss and possibly blindness. [4]
