[Long-term results following cemented total hip alloplasty in primary hip arthrosis. What to expect?].

The aim was to investigate the age-, gender- and implant related survival up to 14 years postsurgery in patients with primary hiparthrosis in one or both hips and operated in county hospitals with cemented prosthesis designs. The subjects consisted of 1,199 patients operated in the years 1981-1990, and the cohort was followed till 31.12.1994. The 1,199 patients had a total of 1,477 cemented total hipalloplastics (THA's) inserted. Two hundred and fourty-eight patients died during follow-up. Until 1990, 278 patients had had both hips operated, and a further 58 patients had the contralateral hip operated during follow-up to 31.12.1994. Fourty-nine hips were revised between four and 14 years (median: nine years) postsurgery. The cumulative survival for all THA's was 92.5%. Respective figures for the Richard Series 2 and the Charnley-prosthesis were 91.5% and 92%, now more than 14 years from the first operations. In conclusion, cemented total hip arthroplasty is a good treatment option for patients with primary hip arthrosis. Younger patients have an increased risk of revision, and alternative fixation may be considered. With an overall prosthesis-survival more than 14 years postsurgery of 92.5%, the treatment can take place at local orthopaedic departments. Our results are comparable to figures from the Swedish national register.

[Age and sex specific incidence of primary total hip alloplasty in the county of Southern Jutland].

During the 10-year period 1981-90, 1752 primary total hip arthroplasties (THAs) were performed in the county of south Jutland, Denmark. The annual number of THA increased until a steady state level was reached during 1988-90. The age and sex specific incidences were calculated for this period using the population distribution of the County. The age specific incidences were highest in the age-group 70-79 years for both female and males, namely respectively 485 and 410 THAs per 100,000 inhabitants. The overall incidence was 82 THA per 100,000 inhabitants. During the next 30 years, the demand for primary THA in Denmark is expected to increase 32 percent (from 4013 to 5307 THAs) as a consequence of demographic changes.

Hip arthroplasty in Jutland, Denmark. Age and sex-specific incidences of primary operations.

During the 10-year period 1981-90, 1752 primary total hip arthroplasties were performed in the County of South Jutland, Denmark. The annual number increased to a steady state during 1988-90. In this period, the incidence was highest in the age group 70-79 years for both women and men, with 485 and 410 arthroplasties per 100,000 inhabitants, respectively; the overall incidence was 82 per 100,000 inhabitants. During the next 30 years, the demand for primary hip arthroplasties in Denmark is expected to increase because of demographic changes.

[The value of 1-year follow-up after total cemented hip alloplasty. Clinical and economic consequences of a routine check-up].

The need for, expenses of and consequences of one year follow-up after total cemented hip replacements with posterior access are reviewed. A total of 150 patients were registered prospectively and consecutively with Charnley scores preoperatively, three months and one year after operation. The Charnley scores increased significantly from the preoperative values till the follow-up at three months and from the follow-up at three months till follow-up at one year (p less than 0.001). In five patients, (3%) follow-up examination after one year was of significance. Anisomelia was corrected in all three by means of adjustment of footwear. The cost of follow-up examination after one year is estimated to be 630 Danish crowns (approximately 53 pounds) per patient. It is concluded that follow-up examination after total cemented hip replacement is not necessary. Alteration of follow-up examination after one year to follow-up examination after five years for patients who were under 60 years at the time of operation in order to reveal aseptic loosening would imply that only 10% of the patients in this material should be followed-up.

Aseptic loosening of the Monk hip prosthesis.

In a preliminary report concerning 104 Monk arthroplasties satisfactory results were found within an observation time of 1.6 years (Hansen & Rechnagel 1977). However an early tendency for aseptic loosening was recorded. At a follow-up of the same patients after 5 years it was found that 17 patients, with their primary prostheses in place, had died. Of the remaining 86 prostheses not less than 50% had been removed because of loosening causing symptoms. Furthermore at re-examination of 39 patients with 43 of the primary prostheses still in situ radiological and clinical evidence of progressive aseptic loosening was present. The aetiology of the loosening is discussed and it is suggested that wear of the polyethylene cap plays an important role. It is concluded that the "soft top" Monk prosthesis cannot be recommended for replacement arthroplasty of the hip.

Unstable trochanteric fractures treated with the sliding screw-plate system. A biomechanical study of unstable trochanteric fractures. III.

Eighty unstable trochanteric fractures were treated with the sliding screw-plate system. Early weight-bearing was encouraged and mobilization was obtained within the first week in 47 per cent of the cases (37/78). Technical complications were encountered in 5 per cent of the patients (4/76) but none required re-operation. Telescoping of the screw occurred in 49 per cent (37/76). Through this secondary fracture impaction a stable load transmission system was established. Fracture union in the postoperative position was obtained in 49 per cent of the patients (37/76) and non-union did not occur.

Isolated lesions of the radio-ulnar disk treated with excision.

Twelve patients with isolated lesions in the radio-ulnar disk are reviewed. In the traumatic cases, where peripheral ruptures were found at operation, the results after excision were satisfactory, whereas patients with no evident traumatic etiology, where a degenerated disk was found, did not benefit from the excision. Resection of capitulum ulnae is recommended in such cases.

Surgical treatment of axillary hyperhidrosis in 123 patients.

123 patients suffering from axillary hyperhidrosis have been operated on as outpatients under local anaesthesia, with radical ablation of sweat glands. All except 7 patients were satisfied with the result. There were few complications. A group of patients and controls were extensively studied including quantitative sweat testing and axillary biopsis. Apart from increased axillary sweating during the test, no differences could be found. The basic etiology of the condition is still unknown.
