A waterbed, water mattress, or flotation mattress is a bed or mattress filled with water. Waterbeds intended for medical therapies appear in various reports through the 19th century. The modern version, invented in San Francisco and patented in 1971, became a popular consumer item in the United States through the 1980s with up to 20% of the market in 1986 and 22% in 1987. Currently they account for less than 5% of new bed sales.
Orthopedic surgery or orthopedics, also spelled orthopaedics, is the branch of surgery concerned with conditions involving the musculoskeletal system. Orthopedic surgeons use both surgical and nonsurgical means to treat musculoskeletal trauma, spine diseases, sports injuries, degenerative diseases, infections, tumors, and congenital disorders.
An air mattress is an inflatable mattress or sleeping pad.
A mattress is a large, rectangular pad for supporting the reclining body, designed to be used as a bed or on a bed frame, as part of a bed. Mattresses may consist of a quilted or similarly fastened case, usually of heavy cloth, that contains materials such as hair, straw, cotton, foam rubber, or a framework of metal springs. Mattresses may also be filled with air or water.
The sacroiliac joint or SI joint (SIJ) is the joint between the sacrum and the ilium bones of the pelvis, which are connected by strong ligaments. In humans, the sacrum supports the spine and is supported in turn by an ilium on each side. The joint is strong, supporting the entire weight of the upper body. It is a synovial plane joint with irregular elevations and depressions that produce interlocking of the two bones. The human body has two sacroiliac joints, one on the left and one on the right, that often match each other but are highly variable from person to person.
A bed is a piece of furniture which is used as a place to sleep, relax, or engage in sexual activity.
Hip replacement is a surgical procedure in which the hip joint is replaced by a prosthetic implant, that is, a hip prosthesis. Hip replacement surgery can be performed as a total replacement or a hemi (half) replacement. Such joint replacement orthopaedic surgery is generally conducted to relieve arthritis pain or in some hip fractures. A total hip replacement consists of replacing both the acetabulum and the femoral head while hemiarthroplasty generally only replaces the femoral head. Hip replacement is currently one of the most common orthopaedic operations, though patient satisfaction short- and long-term varies widely. Approximately 58% of total hip replacements are estimated to last 25 years. The average cost of a total hip replacement in 2012 was $40,364 in the United States, and about $7,700 to $12,000 in most European countries.
A bed sheet is a rectangular piece of cloth used either singly or in a pair as bedding, being placed immediately below or above bed occupants. A top sheet, in the many countries where they are used, is a flat sheet, immediately under which bed occupants lie. A bottom sheet is laid above the mattress and bed occupants lie on it. A bottom sheet may be either a flat sheet, or a fitted sheet, which has been sewn to form a large pocket around the top, sides and bottom edge of a mattress, with elastic or a drawstring in the hem to stop it slipping off the bottom of the mattress. Blankets, quilts, duvets, comforters and other bed covers are laid over the top sheet.
Memory foam consists mainly of polyurethane as well as additional chemicals increasing its viscosity and density. It is often referred to as "viscoelastic" polyurethane foam, or low-resilience polyurethane foam (LRPu). The foam bubbles or ‘cells’ are open, effectively creating a matrix through which air can move. Higher-density memory foam softens in reaction to body heat, allowing it to mold to a warm body in a few minutes. Newer foams may recover more quickly to their original shape.
Spinal manipulation is an intervention performed on spinal articulations which are synovial joints, which is asserted to be therapeutic. These articulations in the spine that are amenable to spinal manipulative therapy include the z-joints, the atlanto-occipital, atlanto-axial, lumbosacral, sacroiliac, costotransverse and costovertebral joints. National guidelines come to different conclusions with respect to spinal manipulation with some not recommending it, and others recommending a short course in those who do not improve with other treatments.
A bed frame or bedstead is the part of a bed used to position the mattress and base (foundation), and may include means of supporting a canopy above. Bed frames are typically made of wood or metal. A bed frame includes head, foot, and side rails. It may also include slats to support the mattress, in which case a separate base is not necessary, as in a platform bed. Most double (full) sized beds, along with all queen and king size beds, require some type of center support rail, typically also with extra feet extending down to the floor. The term "bed frame" was first used in 1805-1815.
An adjustable bed is a bed which has a multi-hinged lying surface which can be profiled to a number of different positions. Common adjustments include inclining the upper body and raising the lower body independently of each other. Other common features include height adjustment and tilting the bed to raise the upper body or the lower body into the Trendelenburg or reverse Trendelenburg positions.
Ankle replacement, or ankle arthroplasty, is a surgical procedure to replace the damaged articular surfaces of the human ankle joint with prosthetic components. This procedure is becoming the treatment of choice for patients requiring arthroplasty, replacing the conventional use of arthrodesis, i.e. fusion of the bones. The restoration of range of motion is the key feature in favor of ankle replacement with respect to arthrodesis. However, clinical evidence of the superiority of the former has only been demonstrated for particular isolated implant designs.
A hospital bed or hospital cot is a bed specially designed for hospitalized patients or others in need of some form of health care. These beds have special features both for the comfort and well-being of the patient and for the convenience of health care workers. Common features include adjustable height for the entire bed, the head, and the feet, adjustable side rails, and electronic buttons to operate both the bed and other nearby electronic devices.
Professor Derek McMinn is a British orthopaedic surgeon and inventor who practises in Birmingham, United Kingdom at the BMI Edgbaston Hospital. Prof. McMinn developed the first successful modern metal-on-metal hip resurfacing and the instrumentation and surgical technique to implant it. Hip resurfacing is a bone-conserving, less invasive alternative to total hip replacement (THR) for young patients, markedly improves the health-related quality of life measures and currently makes up around a tenth of all hip arthroplasty procedures performed in the United Kingdom. McMinn is also the inventor of several other prostheses for the hip and knee.
