Dynamic Compression Plate LC-DCP: Limited Contact – Dynamic Compression Plate. The dynamic compression plate is used like other osteosynthesis plates. Only the drill hole is constructed differently. The geometry of the screw head and plate hole in the DCP is such that a congruent fit is achieved even if the screw is at an angle …
Total hip replacement implants are designed to help a patient get back as close as possible to the healthy, active lifestyle before hip pain limited the mobility. Almost all hip replacement implants have consisted of a three-part system: A hip stem, usually made from such as titanium, which is implanted down the shaft of the …
Locking Compression Plate Locking Compression Plate (LCP) Implants are taken for temporary ﬁxation, correction or stabilization of bones in various anatomical regions. The plates come in different sizes and shapes according to the anatomy and the intended purpose. Screws are locked in the plate, and the physiological load (F) is transferred from the bone to …
Universal Spine System
relating to the maxilla (upper jawbone) and the face. Maxillofacial surgery is a specialization of medicine and/or dentistry that focuses on problems around the mouth, jaw, midface and neck. Anatomical limits and skills differ country-to-country. In some countries doctors attend medical school, dental school and than an additional residency. In other countries they attend either …

Neurovascular Anticipating Distraction Interference Arthrodesis Bridging the sacroiliac joint from posterior to eliminate neurovascular risks, which could happen with laterally-based techniques. (Ilion Medical)
Dynamic Condylar System or Dynamic Condylar Screw The DCS Screw is designed to provide strong and stable internal fixation of certain distal femoral and subtrochanteric fractures, with minimal soft tissue irritation.
Locking Trochanter Stabilizing Plate
Dynamic Hip System (Screw) Dynamic hip screws are a femoral head-sparing orthopedic device used to treat femoral neck fractures. DHS Procedure is done for patients with either a Non-Displaced or Minimally-Displaced Intertrochanteric (between the greater & lesser trochanter) hip fracture.
eXtreme lateral lumbar intervertebral fusion The XLIF (eXtreme Lateral Interbody Fusion) is an approach to spinal fusion in which the surgeon accesses the intervertebral disc space and fuses the lumbar spine (low back) using a surgical approach from the side (lateral) rather than from the front (anterior) or the back (posterior). The XLIF is one …
Arthrodesis (also artificial ankylosis or syndesis), is the artificial induction of joint ossification between two bones by surgery. This is done to relieve intractable pain in a joint which cannot be managed otherwise. It is most commonly performed on joints in the spine, hand, ankle, and foot.
ACI (Autologous chondrocyte implantation) repairs articular cartilage. It works in three stages: 1. Arthroscopically sampling of 200 to 300 mg cartilage. 2. Isolated chondrocytes are grown in vitro for about four to six weeks. 3. Chondrocytes are applied in a second intervention on the damaged area. The autologous cells should adapt themselves to their new …
The excavation of tissue to form a shallow shelving depression, usually performed to facilitate drainage from infected areas of bone. The shallow saucer-like depression on the upper surface of a vertebra that has suffered a compression fracture. Dental: Pericervical depression around an dental implants neck.
Gradual increase in the application of load on an implant.
A fully differentiated cell that originates in the embryonic mesenchyme and, during the early development of the skeleton, functions in the formation of bone tissue. Osteoblasts synthesize the collagen and glycoproteins that form the bone matrix, and also produce inorganic salts. With growth, they develop into osteocytes.
HU A unit of y-ray attenuation used for CT-scans as a measurement of bone density. Each pixel is assigned a value on a scale on which air is -1000, water 0, and compact bone +1000. In dentistry exists a proposal to use bone density as a determinant for clinical success (Misch CE, Contemporary Implant Dentistry, …
Refers to the time of applying force on an implant after initial placement. This term mostly is used in oral surgery/dental implantology. The prosthesis is brought in function earlier than the conventional healing period. Early loading may be applied, if preconditions are good or optimally.
Freeze-dried bone allograft Bone harvested from donor cadavers, washed, immersed in ethanol, frozen in nitrogen, freeze-dried and ground to similar particles ranging from 250 to 750μm. It acts primarily through an osteoconductive process, as inductive proteins, often found in only minute quantities, are only released after the resorption of the mineral.
Surgical technique in which only the bony cortex is surgically cut.
Calcium sulfate (or calcium sulphate) is the inorganic compound with the formula CaSO4 and related hydrates. One particular hydrate is better known as plaster of Paris, and another occurs naturally as the mineral gypsum. All forms are white solids that are poorly soluble in water. Calcium sulfate causes permanent hardness in water. Mixed with polymers, …
Force attempting to disengage parts joined by a screw.
Syn.: Osteodistraction, callus distraction, callotasis. Formation of new bone between vascular bone surfaces created by an osteotomy and separated by gradual and controlled distraction. It is used in orthopedic surgery, podiatric surgery, and oral and maxillofacial surgery. Originally used to treat problems like unequal leg length, it now is used for the treatment of issues …
Autologous Chondrocyte Implantation A technique for the treatment of large isolated cartilage defects. A small sample of cartilage is harvested from a non-weight-bearing part of the joint during arthroscopy. In a laboratory the chondrocytes are dissolved away of the tissue composite and multiplied in culture dishes. After a cultivation period of 3 to 4 weeks …

The term refers to the direct structural and functional connection between living bone and the surface of a load-bearing (Albrektsson et al. in 1981) artificial implant. A more recent definition (by Schroeder et al.) defines osseointegration as “functional ankylosis (bone adherence)”, where new bone is laid down directly on the implant surface and the implant …
Osteolysis is an active resorption of bone matrix by osteoclasts. Although osteoclasts are active during the natural formation of healthy bone the term “osteolysis” specifically refers to a pathological process. Osteolysis may occur around implants by inflammation, immunological response, tumors, cysts or changes in the bone’s structural load.
Posterior Cruciate Ligament
A posterior stabilized knee implant replaces the PCL with a cam and post design of the knee replacement that ensures femoral rollback. The advocates of the PS knee design claim more predictable knee ligament balancing and more predictable flexion. The opposition of PS knee designs claim the cam and post design causes additional polyethylene wear, …
A cruciate retaining knee implant leaves an intact posterior cruciate ligament (PCL) in the back of the knee to help with knee flexion and ligament tension. The advocates of the CR knee design claim less bone removal from the femur, easier femoral component revision, and tighter ligaments in the back of the knee. The opponents …

Anterior Cervical Discectomy and Fusion Anterior Cervical Discectomy and Fusion is cervical spine surgery from the front of the neck that addresses spinal symptoms.
Osteopromotion involves the enhancement of osteoinduction without the possession of osteoinductive properties. For example, enamel matrix derivative has been shown to enhance the osteoinductive effect of demineralized freeze dried bone allograft (DFDBA), but will not stimulate new bone growth alone.
Osteoconduction occurs when the bone graft material serves as a scaffold for new bone growth that is perpetuated by the native bone. Osteoblasts from the margin of the defect that is being grafted utilize the bone graft material as a framework upon which to spread and generate new bone. In the very least, a bone …
GBR is the reformation of bone. This may be induced within a bony structure by a packing material or in excess on the surface of a bony structure by tissue augmentation. A dental surgical procedure using barrier membranes to direct the growth of new bone at sites with insufficient volumes or dimensions of bone, usually …
