Results of total elbow arthroplasty as a salvage procedure for failed elbow reconstructive operations.

Total elbow arthroplasty (TEA) was used as a salvage procedure following failed open reduction and internation fixation, failed triaxial arthroplasties, and septic and aseptic loosening of implant arthroplasty. A minimally constrained bicondylar implant with a block to disarticulation was substituted for the reconstruction of 20 revision TEAs. Custom-designed implant TEA was substituted in cases with substantial bony or soft tissue loss. Revision of the polyethylene-bearing component, coupled with the addition of a yolk-type locking mechanism, was implanted when only the bearing system of a well-fixed implant had failed. TEA can be performed successfully with satisfactory durability as a revision procedure. Revision of failed open reduction internal fixation or a failed bearing system was highly successful. Revision of previously infected elbows in a single-stage procedure was unsuccessful in two of three cases and has been abandoned in favor of a staged procedure. A revision of loose TEA was successful in only three of five cases. Further investigations are necessary to improve the function durability of TEA.

Reduced serum calcium and inorganic phosphate levels in normal elderly women.

Because published data on the effect of normal aging on serum calcium and phosphate levels are scanty and contradictory, we measured these parameters in 36 normal women over the age of 65 and compared these values with those obtained previously and concurrently in younger women. We found a significant decline in both serum calcium and phosphate levels after the age of 65. We also measured corrected total serum calcium, serum ultrafiltrable calcium, and serum ionized calcium levels in all of the elderly women and in 29 of the younger women and concluded that the decline in total serum calcium levels seen with aging was attributable in part to decreased levels of protein bound calcium but that there was also a slight reduction of ionic calcium levels. Data obtained in elderly women with proven parathyroid adenomas are included to illustrate how the recognition of these age related changes in total serum calcium levels may aid in the identification of slight but clinically important hypercalcemia in elderly adults.

Clinical assessment of the elderly patient.

The examination of an elderly patient often requires special techniques and attention to the patient's comfort and ease. This paper outlines a reasonable approach to each phase of the interview and discusses the particular medical problems of this age group. Older people are often slow to bring their troubles to medical attention because their symptoms are vague or because they accept their disability as part of old age. Sometimes they have difficulty in communicating effectively with the physician. Simple patience can ease an otherwise frustrating situation.

Management of gallstones in the aged.

Calculous gallbladder disease is the most common indication for intra-abdominal surgery in the elderly. Feeding bile salts may possibly increase the solubility of cholesterol in bile and may cause diminution in the size of radiolucent gallstones, the principal ingredient of which is cholesterol. However, indications for such treatment are still not clear, and long-term effectiveness and safety still have to be evaluated. If the aged patient with gallstones has severe symptoms, is a good medical risk and is not demented, surgical treatment should not be denied because of advanced age. If the patient has "silent" or "dyspeptic" gallstones and is a poor risk or demented, surgical therapy should be postponed at least temporarily, in the hope that medical methods for dissolving gallstones soon will be perfected.

Nonconstrained total elbow arthroplasty.

Twenty-eight nonconstrained capitellocondylar elbow offhroplasties were performed in 23 patients. The clinical criteria were intractable pain in a joint with radiologic destruction from rheumatoid arthritis. Patients were examined at an average of 35 months postsurgery with the Ewald scoring system. Results were satisfactory in 24 elbows (86%) and unsatisfactory in four (14%). Pain relief and functional improvement were dramatic. The average arc of motion increased from 88 degrees preoperation to 101 degrees postoperation. There was an average 33 degrees residual flexion contracture. There was one failure from loosening, but no radiographic or clinical loosening was detected in the remaining patients. Postoperative dislocation was the most frequent complication, occurring in four cases. One dislocation required revision while three stabilized following four weeks of immobilization. There were two remote infections occurring two and five years postoperation. Although complications are frequent, this is a predictably successful procedure in properly selected patients.
