Prevalence of degenerative joint complaints of the lower extremity: a representative study.

As part of the international campaign of the bone and joint decade, we aimed to present epidemiological data on the prevalence of major joint complaints in a Central European region. Ten thousand subjects aged between 14 and 65, selected randomly by the Hungarian central office of statistics from three counties in southern Hungary, were surveyed using our own questionnaire based on widely accepted scoring systems in the literature, focusing on major degenerative joint complaints, and using the short form 36 (SF-36) questionnaire. We found that the prevalence of hip pain in the observed group was 22.2%, the prevalence of knee pain 30.3%, and frequent ankle pain occurred in 9.7%. The results of the SF-36 questionnaire showed that with the exception of social function, neither of the values of the examined health dimensions reached levels of other international surveys. Details of the survey and the possible causes of the higher prevalence are discussed, along with the results of the SF-36 questionnaire.

The surgical treatment of spinal deformities in the Department of Orthopaedic Surgery, University Medical School of Pécs, Hungary: history and development.

Since its foundation in 1966, a great deal of attention has been paid to the treatment of spinal deformities, especially idiopathic scoliosis, in the Department of Orthopaedic Surgery, Medical School of University, Pécs. The authors compared the results of three different surgical methods (modified Hibbs, Harrington, Cotrel-Dubousset) on 171 patients between 1966 and 1992. The average follow-up period was between 2 and 13.2 years. In cases in which the modified Hibbs procedure was used we achieved a 26% correction, in the Harrington cases we achieved a 43.9% correction, and the loss of correction was 100% after the Hibbs operation and 18% after the Harrington operation in the follow-up period. In cases of Cotrel-Dubousset Instrumentation we achieved about 70% correction, but the follow-up period was too short (2 years) to evaluate the loss of correction in these cases.

Long-term results of the operative treatment of clubfoot: a representative study.

This study reports the long-term results of operative treatment of clubfoot. Of the patients who underwent posteromedial release for congenital clubfoot between 1972 and 1975 at the Medical University in Pécs, Hungary, 41 feet of 30 patients have been under control examination. Control consisted of the distribution of questionnaires, physical examination, and in some cases, radiologic analysis. At an average of 20 years postsurgery, good clinical results were observed in 31 (75%) feet. In these patients, satisfying foot form and good function were achieved, yet the characteristic atrophy of the calf and shortening of the foot were visible. Abnormal conditions were found in 10 feet, consisting of overcorrection in 6 and undercorrection in 4 cases. Subjective judgment of the patients was considerably better; only 5 (12%) feet had no satisfying results. Data of feet in an incorrect position were analyzed and compared with other cases. In cases of feet operated on in patients aged > or = 1 year and in patients who underwent multiple operations, abnormalities were found in a significantly higher percentage.

[Management of calcaneonavicular coalition and results].

26 cases of calcanconavicular coalitions were treated by resection of the calcanconavicular bar. The endresults were markedly influenced by the age at surgery, while there was no difference between the "bone" and "cartilage" group. The coalition must be recognised if someone examinates a rigid flatfoot.

[Results of osteotomies in the management of valgus gonarthrosis].

Authors report on the result of correction osteotomies in 31 cases of gonarthrosis, developed in consequence of valgus deformity. In 12 cases high tibial osteotomy, in 19 supracondylar femoral osteotomy were performed. The result was excellent in 15, good in 10 and poor in 6 patients. Decisive factors of the favourable result were partly the correction of the femorotibial valgus to around the physiological values, partly the horizontalization of the articular surface. In overcorrection the results deteriorate. The medial tilt of the tibial articular surface leads to the progression of the arthrosis. Supracondylar femoral osteotomy was found especially successful in the treatment of valgus gonarthrosis. High tibial osteotomy is suggested only in selective cases.

Results of ultrastructural analysis of the calf muscles in clubfoot.

Open biopsies were carried out on the muscles of 23 clubfoot patients, ages 9 months to 4 years. Electron microscopic analyses of the so-called "clubfoot muscles" and the peroneal muscles were performed. The changes found were not present in every area of the muscles, but were surrounded by fields of normal structure. Fatty degeneration with fibrosis was observed as the consequence of immobilization. More marked loss was found in the contractile elements. The authors believe that neuromuscular atrophy is a primary cause of congenital clubfoot. The most seriously affected muscles in this study were the tibialis posterior and peroneal muscles. The material failed to prove correlation with age. Based on their observations, the authors suggest finishing all types of immobilization before 1 year of age, when children begin to walk.

[Management of varus knee arthrosis by high tibial osteotomy].

Authors made a follow-up of 69 varsus knee arthrosis treated with high tibial osteotomy. Beside the general results the effect of the severeness of the arthrosis before the correction and that of the gain of the axial correction on the result were also investigated. 56 (81 per cent) of the reexamined patient reported excellent or good results. The ratio of the successful operations was even higher in cases in which the femorotibial axis was corrected to physiological valgus (95 per cent). The best prognosis of the osteotomy is in the early stage of arthrosis (Ahlbäck 0-II). In cases of the more advanced process the ratio of the unsuccessful cases increases. In consequence it is stated that the best results can be expected after osteotomies performed in the early stage and leading to the physiological femorotibial valgus position.

[Complete surgical correction of congenital hip dislocation (one-stage surgery)].

A 3-10 years follow-up and the evaluation of the 55 cases operated 1980 through 1988 on the Orthopaedic University Hospital in Pécs is presented. The age of the patients at operation was 4.5-10 years, in average 4 years. The operation consisted of four components: operative reduction, varus derotation femoral osteotomy, acetabular plasty and transposition of the iliopsoas muscle. In 53 cases excellent or good Roentgen anatomical and functional results were found. In one case after the operation complete femoral head necrosis has developed, in two cases a transient ischaemic state was observed that healed however without functional deficiency.

[Vertical talus].

Authors differentiate four etiological groups of vertical talus. In their material the congenital and symptomatic rocker bottom foot was rarer than the paralytic one. Good result can be expected mainly from the operative treatment. From 69 cases good clinical and radiological result was reached in 58, whereas in 6 cases the treatment had no result. It was their experience that a reduction of the talus and of the navicular bone can be reached by tenotomies and capsulotomies and by these a normal form of the foot can be secured. In the conservation of the operative results the significance of the organized care is stressed.

[The use of CO2 laser in bone surgery].

Authors examined during the trial of a CO2 laser of type TUNGSRAM TLS-61 the possibility of its use in the orthopaedic surgery. The output necessary to cut the skin and bony tissue, the speed of cutting and the extension of tissue necrosis were determined in experiments in vitro and in vivo. According to their observation the fusion of the bone cut with CO2 laser takes the same time as after the traditional osteotomy, however in the first three weeks the callus formation falls behind. The possibility of a curved cutting and of the coagulation haemostasis may ensure a fine prospect to this method.

Confirmation of the multifactorial threshold model for congenital structural talipes equinovarus.

The first degree relatives of 174 children with congenital isolated structural talipes equinovarus were examined by an orthopaedic surgeon. The affected rate of first degree relatives was 27 times higher than the birth prevalence of Hungarian newborns. The heritability in the parents and sibs was 0.82 +/- 0.15. The multifactorial threshold model was proved by the so-called GAMT programme on the basis of the identity of the h2 values in the different generations of first degree relatives. A relatively lower familial clustering was found in gypsies who had a higher prevalence.

[The effect of operations on soft tissues in the development of tarsal bones in patients with clubfoot (author's transl)].

Authors investigated the process of ossification of tarsal bones in patients with club foot previously treated with redression in plaster and soft tissue release. A control group of 150 children between 1 and 12 years of age without club foot deformity was used. Based on analysis of two side X-ray pictures it is stated that 17.8 per cent of cases with club foot reveal a general backwardness and other variables of ossification. No obvious damaging effect of the operation was observed. In their opinion by means of soft tissue release the noxious effect of forced manipulation can be prevented. By ceasing the malposition in time the ossification can be accelerated.

[Ultrastructural investigation on muscles of patients with talipes equinovarus (author's transl)].

Authors in course of soft tissue release of children with talipes equinovarus between the age of 9 months and 4 years performed a muscle biopsy in 23 cases from the so called club foot muscles and from the peronei. The results of electronmicroscopic investigation are described. The muscle is not as a hole affected, but the pathologic parts are scattered among the intact ones. Fatty degeneration was noted after long termed redression in plaster, together with the fat connective tissue also appeared. The most severe alterations were observed on the contractile elements, consistent seemingly with neuromuscular atrophy. The posterior tibial muscle and the peronei revealed the most obvious alterations. With rising age there was no deterioration of the picture. On basis of their results it is suggested, that for children starting to walk all kind of treatment involving immobilisation should be abandoned, and after operation a functional treatment with eventual electrotherapy introduced. This is in their opinion only realizable in frame of organized care.

[Results of soft tissue operations in the management of congenital club foot (author's transl)].

A review is given on the experiences of 152 cases of operatively treated club foot. Exact X-ray assessment is thought to be very important, as even after excellent morphological and functional end results residual X-ray changes have been observed which potentially may lead to the redevelopment of abnormalities. Clinical and radiological assessment together can only be informative of the result of management. Analysis of the "own" and "referred" patients showed better clinical and radiological results in the first group, which has been attributed to the early operation, regular follow-up and care.

[Congenital knee luxation].

The authors discuss the frequency, etiology, symptoms and classification as well as treatment of congenital dislocation of the knee. 8 own cases are reported in the article. The authors suggest that congenital dislocation of the may be well influenced by non-operative methods. Etappe redressement by means of plaster does not interfere with the functional treatment of the hip dislocation usually treated with the Pavlik braces. Associated foot deformities may be easily corrected at the same time. The so called "earliest treatment" is most important in all the three deformities (knee-hip dislocation, club foot), the authors emphasise.
