[Postoperative autologous transfusion from blood drainage after total hip joint arthroplasty--how much value is really there?].

AIM: Are autologous blood transfusions sufficient or do we need the transfusion of unwashed or washed wound drainage blood in total hip arthroplasty? METHOD: 253 patients undergoing total hip arthroplasty were retrospectively randomized to autologous blood transfusion or transfusion of unwashed wound drainage. We compared the haemoglobin and haematocrit levels as well as the rate of complications. RESULTS: Postoperative blood salvage and reinfusion after total hip joint arthroplasty didn't show any advantages. In 10 % we saw complications after transfusion of unwashed wound drainage. CONCLUSION: We do not recommend the transfusion of wound drainage.

Revision total hip arthroplasty in hip joints with metallosis: a single-center experience with 31 cases.

Clinical and radiographic findings of metallosis in relation to the clinical outcome of revision total hip arthroplasty were analyzed for 31 hips. Causes of metallosis were dissociation of polyethylene liner in 24 hips, catastrophic wear in 6, and the screw used for stem fixation in 1. Metallosis was grade I in 12 hips, grade II in 7, and grade III in 12. Osteolysis around the acetabular cup was observed in 24 (77.4%) of 31 hips. At the time of final follow-up evaluation, none of the hips showed osteolysis, acetabular cup migration, or any change in inclination. Although metallosis could not be completely eradicated in severe cases, the clinical outcome for these hips was favorable. This study demonstrates that metallosis frequently causes osteolysis and that complete elimination of it is not a prerequisite for the success of revision total hip arthroplasty.

Pigmented villonodular synovitis of the hip joint (review of the literature and report of personal case material).

The authors illustrate the diagnostic and therapeutic problems posed by pigmented villonodular synovitis of the hip by reviewing the literature and reporting on six original cases. Four of these cases were treated by synovectomy and two by prostheses. The best results were obtained with the total prostheses, but this must be considered in the light of the fact that most of the patients were young.

Medical devices; reclassification and codification of hip joint metal polymer/metal semi-constrained porous-coated uncemented prosthesis--FDA. Final rule.

The Food and Drug Administration (FDA) is announcing the reclassification and codification of the hip joint metal/polymer/metal semi-constrained porous-coated uncemented prosthesis. FDA issued an order in the form of a letter to two manufacturers reclassifying the device from class III into class II. Accordingly, FDA is amending the regulations as set forth below.

[Experimental testing of an isolating-clutch endoprosthesis of the hip joint: the first results].

The paper presents the results of experimental tests of a new endoprosthesis. The study is devoted to the important issue the prevention on hip joint endoprosthetic instability occurring due to metallosis and its tissue responses. The prosthesis has the new design element an artificial capsule that protects tissue from metallosis. Experimental data were obtained by clinical observations of surgery-undergone dogs aged under a year and by X-ray, morphological and spectral studies. That the artificial capsule is highly effective in preventing the instability of the prosthesis and that the function of a limb is not limited by the capsule are shown.

Elements of hip joint prosthesis reliability.

The performance of a total hip prosthesis is considered in terms of reliability. The causes requiring removal of the prosthesis are considered and methods of avoiding these difficulties are outlined. It is pointed out that most attention must be focused on the areas of low reliability. The goal of increasing prosthesis lifetime must be shared between the surgeon and manufacturer.

Measurement of strength of hip joint muscles.

A standard procedure for measurement of hip muscle strength with an isokinetic dynamometer is presented. The method is based on recordings in supine position and firm stabilisation of the pelvis. Abduction and adduction movements can be done without friction. The position of the dynamometer and its rotation centre is indicated. The reproducibility was studied by a test-retest procedure. The methodological error varied between 4% and 10.5% and the coefficient of reliability varied between 0.80-0.99. The coefficient of variation when measuring one testing subject at ten different occasions was smaller at isokinetic than isometric measurements.

[Frequency of necroses of the head of the femur in the treatment of the so-called congenital dislocation of the hip joint according to Hoffmann-Daimler (author's transl)].

The article reports on the results which can be obtained with the method described by Hoffmann-Daimler regarding the functional treatment of the so-called congenital dislocation of the hip joint. The report is based on a patient material of 110 children with 159 dislocated hips treated at the Orthopaedic University Clinic at Erlangen between 1971 and 1976. Observation of the course of the disease revealed a much lower rate of incidence of necrosis of the head of the femur than stated in literature, using the Hoffmann-Daimler method. The incidence of necrosis on pre-treatment of most children with other therapeutic methods, was 2.3% at the beginning of the Hoffmann-Daimler treatment, and increased to 12.7% up to the end of the treatment, dropping to 9.3% at the time of the follow-up examination.

[Changes in collagen biosynthesis in patients with hip joint replacement surgery and reoperation].

The authors investigated the intensity of collagen synthesis in patients subjected to operation or re-operation of a total endoprosthesis of the hip joint. The patients suffered from osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. The authors assessed the activity of collagen glucosyl transferase (S-GGT) and the concentration of the N-terminal propeptide procollagen type III by two methods (S-Pro III-N-P and S-Fab) in serum before and after operation. A significant rise of S-GGT and S-Fab, as compared with controls, occurred only after operation while S-Pro III-N-P was elevated already before operation. S-GGT did not differ before and after operation, while N-propeptide concentration rose when either method was used.
