[Problems of alloplastic joint replacement (author's transl)].

Nowadays artificial joint substitution can be assessed as a definite part of orthopedic surgery. The good primary results must not obscure the fact that in spite of great progress in the field of endoprosthesis, numerous problems must still be considered unsolved. Most important are the problems associated with anchoring the implant into living bone tissue. New ways of cement-free anchorage are being sought. The presentation of possible alternatives and their indicative limitation to alloplastic joint substitution shows that there are possibilities which can be carried out before a possible artificial joint substitution or instead of it. Since joint substitution is still in a phase of development, further advances may be expected in the future.

Analysis of the shoulder implant.

Total shoulder arthroplasty (TSA) is implemented for the relief of pain and better joint function. It is desirable that the TSA can achieve and maintain a long-term and secure fixation of the implanted components. The previous biomechanical studies of shoulder implants were simplified and limited to the two-dimensional (2-D) computational finite element analysis (FEA). In this research, reliable 3-D FEA models were established and used to examine the contact stress distribution, contact region and deformation of implant. Based on FEA results, the design of current shoulder implants can be modified for optimum performance. The substantiated 3-D FEA models can provide important engineering data and clinically useful information toward the development of better shoulder implants for a long-term fixation.

Preoperative and postoperative management: the role of allied health professionals.

The success of a coordinated team approach is dependent upon respect and communication among all members, all directed toward the individual patient's goal. Standardized forms can be developed by each discipline and used as a formal mode of communication. These can be available in each patient's record for all the professional staff to read. Unitization has established an atomosphere for informal ongoing communication: i.e. allied health team members have been assigned to the same patient care unit. The same allied health members are therefore working together with the same patient on a day by day basis. Greater efficiency and communication tend to develop spontaneously within such a system. Full inpatient coverage seven days a week by the therapist as well as the nurses has improved continuity of care. Since these changes in staff distribution have taken place, a study of a significant number of patients undergoin total knee or toal hip procedures has shown that there has been a reduction in the average length of stay for the hospitalization, from two days for a total knee replacement to five days for a patient undergoing total hip replacement. Weekly or twice weekly meetings of allied health members, surgeons, and rheumatologists greatly facilitate the progression and coorination of the treatment program. Medical and nursing audits on patients with total hip procedures document a remarkably low rate of surgical complications. Early discharge planning has fostered a smooth transition of the patient to his home and ultimately to work.

Popliteal artery obstruction following Shiers total knee replacement. A case report.

Popliteal artery obstruction may occur following total knee replacement in cases of ankylosis with severe flexion contractures. Immediate recognition and documentation by arteriography is essential. Release of the musculofascial structures in the popliteal area with division of branches of the artery (without exposure of the joint or femur) may relieve the obstruction.

Total knee arthroplasty after septic arthritis.

Total knee arthroplastie were performed as salvage procedures in 1- patients with irreversible knee destruction secondary to bacterial arthritis. All now have functioning knees that are pain-free and average 85 degrees of motion. None has evidence of clinical infection at present. These patients are not yet regarded as cured. They may remain at risk for the development of late reinfections. This procedure is not advocated as the operation of choice for patients with knee joint destruction secondary to bacterial arthritis. We emphasize the risk involved and the necessity for obtaining the informed consent of the patient before proceeding with total knee arthroplasty when there has been previous infection.
