What's the difference between acetabular and cotyloid?
Acetabular
Definition:
(a.) Cup-shaped; saucer-shaped; acetabuliform.
Example Sentences:

(14) In the hips with acetabular protrusion, preoperative values of the force were less than in that the trochanter united and postoperative increase in the abductor force was noted.
(15) In particular, pain was reduced in cases of mobilisation of the acetabular component, and persisted when mobilisation was in the femoral component.
(16) The initial injury had been a posterior dislocation without associated fracture of the acetabular wall, and the hip had not been immobilised or protected from weight-bearing during treatment.
(17) If the criteria for success of major superior acetabular allografts include incorporation of the graft and long-term stability of the implant, then the success rate in this series is very low.
(18) This preoperative acetabular index of 46 degrees improved to 28 degrees postoperatively, and proved to be the most reliable indicator for need of an added pelvic osteotomy.
(19) Major clinical findings include: asymmetric bilateral cryptophthalmos, unilateral orbital cyst of the nasofrontal area, bilateral anophthalmos, right choanal atresia, right microtia, right auditory canal atresia, hypodontia, ankyloglossia, cartilaginous synchondroses of the cervical vertebrae, and bilateral acetabular dysplasia.
(20) Quantification of acetabular coverage is important and can be expressed by superimposition of cartilage tracings on the maximum cross-sectional area of the femoral head.
Cotyloid
Definition:
(a.) Shaped like a cup; as, the cotyloid cavity, which receives the head of the thigh bone.
(a.) Pertaining to a cotyloid cavity; as, the cotyloid ligament, or notch.
Example Sentences:
(1) The authors describe a clinic case regarding a 23 year-old man affected by an osteoid osteoma of the hip's posterior edge of the cotyloid cavity.
(2) Arthroplasty of the hip with a pair of locked cupolas uses a metal cupola and a polyethylene cotyloid cupola.
(3) 5 failures are to be deplored, one by fracture of a 22 mm ceramic head, the normal size in this series being 32 mm; the 4 others occurred after 6, 6, 10 and 11 years and are the consequence of a cotyloid loosening.
(4) Direct measurement of cotyloid anteversion on Arcelin's surgical lateral image showed this method to be a simple, reliable, direct procedure for determination of cotyloid anteversion of total hip prosthesis.
(5) A surgical treatment with the use of an internal extraarticular compression was undertaken in 55 cases of tuberculous coxitis, mainly characterized by a severe destruction of cotyloid cavity and hip joint proximal end.
(6) CT made it possible to establish anteversion of the cotyloid cavity, its degree, the shape and structure of the anterior and posterior wall of the cotyloid cavity, and a shift of the proximal hip end anteriorly in combination with the above changes in the whole hip joint.
(7) In conclusion, it is recalled that prognosis in fractures of the femoral neck is severe for generally gerontological reasons and the usefulness of biarticular endoprosthesis in the prevention of cotyloid wear and tear is underlined.
(8) Measurement of anteversion of cotyle of total hip prosthesis generally involves projection of equatorial guide included in cotyloid piece.
(9) Recollection of pelvic ossification is done insisting upon the primary ossification points, the triradiate cotyloid cartilage and the secondary ossification points.
(10) The author describes a method of autoplastic substitution of defects in the most loaded portions of the cotyloid cavity in patients with tuberculous coxitis.
(11) In the present work, from the position of final outcomes, have been analyzed the results of treatment of bilateral dysplastic femur dislocation with application of different methods of femur setting without correction of space position of proximal section of femur and cotyloid cavity.
(12) In cases with a very narrow iliac bone, the acetabular screw ring is seated below the true cotyloid area.
(13) Access to the capsule is wide and, provided one works on an orthopaedic operating table, the manoeuvres required to dislocate the joint and expose the femoral head and neck, then the cotyloid cavity, are simple.
(14) Using a standing frontal image of hip, the cotyloid borders are identified and a single-plane geometric projection determines the precise degree of version.
(15) Ultrasonographic investigation permits to determine and measure the diameter of cartilaginous head of femur, evaluate its relation to cotyloid cavity, measure the center of the head ossification.
(16) Concerning 14 cases with a follow-up of over 5 years, the authors describe their acetabuloplasty technique which is applied to dysplastic sockets with normal cotyloid cavity anteversion, innominate osteotomy is reserved for cases in which this anteversion is excessive; results have been excellent for 11 cases with adequate lowering of the roof-edge of the cavity and improvement of the C and CE angles as well as satisfactory subsequent bone growth; the result was insufficient in 3 cases in which either the head of the femur was off-centre or deformed by osteochondritis.
(17) Chronic forms of osteoarthritis consisted in the surgical treatment of the purulent focus and filling the cotyloid cavity with a muscular flap or the proximal end of the femoral bone.
(18) A simple, reproducible and reliable method is proposed for measurement of cotyloid version.
(19) Indications for pelvic osteotomy are formed on the basis of roentgeno-anatomic interrelations in hip joint, where the decisive part is played by the angle of vertical inclination of the cotyloid cavity and degree of coating of the head of the femur.
(20) In the process of mobilization operation in case of hyperplastic, coxarthrosis, removal of the lower edge of cotyloid cavity is the obligatory step.
