The device is intended for: - skeletally mature individuals undergoing primary surgery for total hip replacement - patients suffering from severe hip pain and disability due to rheumatoid arthritis, osteoarthritis, traumatic arthritis, polyarthritis, collagen disorders, avascular necrosis of the femoral head and nonunion of previous fractures of the femur. - patients with congenital hip dysplasia, protrusion acetabuli, or slipped capital femoral epiphysis - patients suffering from disability due to previous fusion - patients with acute femoral neck fractures ## Device Story Metha® Short Stem Hip System XL Femoral Head is a modular hip prosthesis component; manufactured from CoCrMo alloy. Used in total hip replacement surgery; implanted by orthopedic surgeons in clinical settings. Device serves as a femoral head replacement; available in 28mm and 32mm diameters. Provides surgeons with additional sizing options to accommodate patient anatomy. Functions as part of a semi-constrained hip system; press-fit fixation. Output is a mechanical interface for hip joint articulation; restores joint function and mobility; reduces pain associated with degenerative or traumatic hip conditions. ## Clinical Evidence Bench testing only. Testing conducted per FDA guidance for orthopedic devices, including metallic plasma sprayed coatings, modular implant components, acetabular cup prostheses, and femoral stem prostheses. ## Technological Characteristics Material: CoCrMo alloy (ISO 5832). Form factor: Modular femoral head, 28mm and 32mm diameters. Fixation: Uncemented, press-fit. Intended for use with semi-constrained hip systems. ## Regulatory Identification A hip joint femoral (hemi-hip) metallic cemented or uncemented prosthesis is a device intended to be implanted to replace a portion of the hip joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum. This generic type of device includes designs which are intended to be fixed to the bone with bone cement (§ 888.3027) as well as designs which have large window-like holes in the stem of the device and which are intended for use without bone cement. However, in these latter designs, fixation of the device is not achieved by means of bone ingrowth. ## Predicate Devices - Metha® Short Stem Hip System ([K080584](/device/K080584.md)) - BiContact Hip System and Femoral Head ([K040191](/device/K040191.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
