Design Optimization of a Prosthesis Stem Reinforcing Shell in Total Hip Arthroplasty

Autor: N. S. Eftekhar, A. M. de Beus, David A. Hoeltzel

Publikováno v: Journal of Biomechanical Engineering. 112:347-357

The use of a perforated, titanium funicular shell to support the proximal femoral cortex in total hip arthroplasty was evaluated with the aid of both analytical and numerical techniques. The principal interactions between the femoral cortex, the meta

Primary Charnley total hip arthroplasty: a comparison of American and Japanese cohorts followed for 10-20 years

Autor: S, Kobayashi, N S, Eftekhar, K, Terayama, R, Iorio, K, Takaoka

Publikováno v: The Journal of arthroplasty. 16(3)

Primary Charnley total hip arthroplasties (THAs) followed for 10 to 20 years were compared between an American (183 sockets and 178 femoral prostheses) and a Japanese (145 sockets and 148 femoral prostheses) series, each performed by a single surgeon

Between 1986 and 1989, 190 patients (214 hips) with the diagnosis of osteoarthritis or posttraumatic arthritis underwent cemented Charnley total hip replacement surgeries via the biplane or single plane transtrochanteric approach. The technique of su

Cemented revision of failed total hip arthroplasty. Survivorship analysis

Autor: R, Iorio, N S, Eftekhar, S, Kobayashi, R P, Grelsamer

Publikováno v: Clinical orthopaedics and related research. (316)

A review of 107 total hip arthroplasties performed with acrylic cement in 89 patients at Columbia-Presbyterian Medical Center by 1 surgeon from 1971 to 1990 revealed a clinical survivorship of 97% at 5 years and 76% at 10 years. The average followup

Risk factors affecting radiological failure of the socket in primary Charnley low friction arthroplasty. A 10- to 20-year followup study

Autor: S, Kobayashi, N S, Eftekhar, K, Terayama, R, Iorio

Publikováno v: Clinical orthopaedics and related research. (306)

To identify the factors affecting Hodgkinson Type 3 or 4 radiological demarcation (presence of complete demarcation or migration, respectively) of the Charnley socket, 328 sockets with 10- to 20-year followup were studied. Fifty-five sockets (16.8%)

Publikováno v: Clinical orthopaedics and related research. (306)

To identify factors affecting radiologically detected loosening of the Charnley femoral prosthesis, 326 femoral prostheses with 10- to 20-year followup were studied. After observation of postoperative radiological changes, the criteria for fixation f

Publikováno v: Clinical orthopaedics and related research. (304)

The radiographs and prospective records of 1284 (1152 primary and 135 revisions) Charnley low friction arthroplasties performed by one surgeon were studied in reference to postoperative elongation of the limb and lateralization or medialization of th
