What is Corail stem?
The CORAIL Stem utilizes compaction broaching which is designed to preserve the blood supply to promote healing and growth of bone around the implant. This technique has shown 93.7% survivorship of the stem at 30 years.
What is Corail Total Hip System made of?
The Corail® stem is made of forged titanium alloy (TiAl6V4). It is a straight implant, with a quadrangular cross section. The proximal part is flared in the sagittal and the coronal plane to provide three-dimensional stabilisation in the metaphyseal area.
What is Corail Pinnacle?
The hip prosthesis consists of 4 major components. A titanium stem (Corail) and titanium bowl (Pinnacle) are placed in the upper leg and pelvic bone, respectively. Both components have been manufactured and distributed for decades by DepuySynthes, a subsidiary of Johnson & Johnson.
What is the constant neck shaft angle of the coxa vara collared stem in the Corail Hip System?
CORAIL Coxa Vara 125° neck angle. Used for coxa vara indications always collared.
What is Porocoat?
Porocoat Coating. The Porocoat coating is a classic porous coating that has been clinically used for more than 40 years. The coating is firmly combined with randomly arranged sintered titanium beads to form interconnected holes for bone growth.
What is Pinnacle cup made of?
Today, the Pinnacle cups come in ceramic-on-polyethylene and metal-on-polyethylene options depending on patient needs. Tapered Hip System stems have been used for more than 15 years to attach hip implants to the femur.
What is the normal angle of coxa vara?
Coxa valga occurs when the angle formed between the neck of the femur and its shaft (also known as the caput-collum-diaphyseal (CCD) angle or the femoral angle of inclination) is increased beyond >140º. Normal is between 125-135º in adults, but can be 20-25º greater at birth and 10º greater in children.
What is COXA Valga and Vara?
Coxa valga is a deformity due to an increase in the angle between the head and neck of the femur and its shaft (normally 135 degrees). Coxa vara is the opposite: a decreased angle between the head and neck of the femur and its shaft.
What is the DePuy summit stem made of?
The Summit® Cementless Hip Replacement System from Depuy-Synthes is a tapered cementless titanium hip stem, whose features include a tapered neck geometry, a Porocoat porous or DuoFix HA coating, an anatomical medial curve, a grit blasted diaphyseal region and a polished distal tip to reduce cortical impingement.
What is Pinnacle hip implant?
More than one million patients have received Pinnacle Hip Solutions cups, according to DePuy. The devices are implanted into the pelvis during partial or total hip replacement surgeries to relieve pain or increase mobility.
What is CCD angle?
The femoral neck-shaft angle (NSA) or caput-collum-diaphyseal (CCD) angle is one of the most frequently applied measurements to assess hip morphology, in particular, the relation of the femoral shaft to the femoral head-neck axis.
Is coxa vara bow legged?
Examples. Hip: coxa vara — the angle between the head and the shaft of the femur is reduced, resulting in a limp. Knee: genu varum (from Latin genu = knee) — the tibia is turned inward in relation to the femur, resulting in a bowlegged deformity. Ankle: talipes varus (from Latin talus = ankle and pes = foot).
How is coxa valga treatment?
Moderate to severe cases are generally treated with physical therapy and the use of canes, walkers, or crutches to make walking easier. If conservative treatment isn’t enough to stop pain, surgery may be done to cut into the femur and decrease the angle of the femoral head.
What is a Hemi in orthopedics?
Hemi means “half” and arthroplasty refers to “joint replacement.” Replacing the entire hip joint is called total hip replacement (THR). A hemiarthroplasty is generally used to treat a fractured hip.
What is the easiest hip replacement surgery?
Anterior hip replacement is a minimally invasive hip surgery performed to replace the hip joint without cutting through any muscles. It is also referred to as muscle sparing surgery because no muscles are cut enabling a quicker return to normal activity.
What is apex distance?
introduced the definition of the tip–apex-distance (TAD) as the sum of the distance, measured on anteroposterior and lateral radiographs, between the tip of the lag screw and the femur head apex. They defined the optimal cut-off for TAD as 25 mm15. In 2012, Kuzyk et al.
What is COXA Vara and Valga?
Coxa valga is a deformity due to an increase in the angle between the head and neck of the femur and its shaft (normally 135 degrees). Coxa vara is the opposite: a decreased angle between the head and neck of the femur and its shaft. Coxa vara is usually indicated when the angle is less than 120 degrees.
