In 1984, bioabsorbable internal fixation devices were used at Helsinki University for the first time as a treatment for fractures and osteotomies of the extremities. Metal plates and screws remain the standard for use in internal fixation, despite the associated risks, including increased infection rates due to bacterial colony formation on the plates, bone atrophy due to stress-shielding (particularly in long bones) and the introduction of growth problems in growing patients. Metal plates and screws must often be removed, requiring a second surgery and exposing patients to the risks of surgery for a second time.
Hip fracture is a common injury that is more frequent with age and has an immediate impact on the quality of life. The approximate one-year mortality rate after a hip fracture is between 20% and 30%. A 2007 study in the American Journal of Therapy showed that fractures repaired within 48 hours of the traumatic incident had better outcomes than those repaired later. The number of annual hip fractures within the senior population alone is estimated to be over 300,000 in the United States, which is equivalent to an incidence rate of almost one per every 1,000 people. Approximately three-quarters of people affected are women, and upwards of 90% of injuries are caused by falls.
Cannulated screws are used for many different types of trauma fixation procedures. The guidewire keeps the unstable bone fragments from moving during screw insertion and allows for continuous fixation. Cannulated screws are designed to fuse multiple bone fragments together. These screws are offered in diameters ranging from under 4 mm to over 7 mm and feature a variety of shaped heads, thread lengths and designs. The analysis herein presents cannulated screws segmented first by headed or headless style and then by size, with large screws having a diameter over 6 mm, medium between 4 mm and 6 mm and small less than 4 mm. Distinctions in screw design can offer better bone purchase and easier extraction.
External fixation is a type of osseous fixation commonly used to treat bone trauma cases and other orthopedic problems. This form of reduction requires drilling holes into unaffected regions of bone around the fracture and screwing bolts or wires into the holes. External fixation is a minimally invasive procedure that is performed by placing a scaffolding frame with associated wires, pins, or both wires and pins on the outside of the damaged extremity. Small pins and wires are then used to hold the bone in its intended position.
Installation of external fixators requires general anesthesia and is usually performed in an operating room. Because the pins pierce through the skin, constant cleaning of the wound is necessary. Removal of the external device can be performed during an office visit without anesthesia.
Intramedullary (IM) hip screws are hybrid devices, incorporating aspects of intramedullary nails and conventional hip screw design. They are inserted into the femur at an angle similar to that of hip screws, but instead of being anchored by a plate external to the shaft of the bone, IM hip screws are anchored inside the medullary cavity. The screws are designed for intertrochanteric or subtrochanteric fractures of the hip. IM hip screws are also known as dynamic hip screws (DHS).
Intramedullary nails, also known as IM nails, IM rods or dynamic intramedullary rods, are solid or cannulated metal rods that are used to align and stabilize fractures. IM nails are inserted into the medullary canal of long bones of the extremities such as the femur, tibia and humerus. The most significant advantage of IM rods over other methods is that they share the weight load with the bone, rather than entirely supporting it. This allows for a more rapid recovery.
Plating devices were pioneered by the Association for the Study of Internal Fixation (AO/ASIF) in Switzerland. Early sales and marketing was done by the Straumann Group, of which the companys osteosynthesis division eventually became Synthes, which was acquired by Johnson & Johnsons Depuy in 2012 to become DePuy Synthes.
Staple fixation devices are divided into two main categories depending on the mechanism by which the compressive forces are applied across the site of fracture. Conventionally, mechanical compression staples, manufactured from either stainless steel or titanium, have been a popular form of fixation for osteotomy and arthrodesis. However, studies have shown that this type of staple provides inconsistent compression and distraction and hence does not result in optimal bone healing. This is in contrast to the second type of staple device: shape memory staples.
This report analyzes the procedure volumes that relate to orthopedic procedures by anatomy within the US between 2013 and 2023. The segments analyzed include: Shoulder Gilder Procedures, Upper Arm and Elbow Procedures, Forearm Procedures, Wrist, Hand and Finger Procedures, Hip Procedures, Upper Leg Procedures, Knee Procedures, Lower Leg Procedures, Ankle Procedures and Foot and Toe Procedures.
The Brazilian orthopedic trauma device market includes plates and screws, intramedullary nails, hip intramedullary nails, compression hip screws, cannulated screws and external fixation devices. All of these segments experienced positive growth in 2011, as the aging population and the high number of motor vehicle accidents in Brazil continued to drive demand. The overall market is largely divided in terms of pricing set by the public SUS system and prices influenced by private insurance companies. The ASPs of products purchased through public healthcare are stable; however, there has been a gradual decline in ASPs in the private healthcare sector. Overall, the strong positive growth in all segments will allow the entire market to grow rapidly over the 20112018 forecast period.
