The importance of arthroscopy in diagnosing synovial haemangioma of the knee joint.

In connection with one of their cases, authors call attention to the importance of differential diagnosis in synovial haemangioma of the knee joint, a rare condition. They also give a survey of its clinical, radiological and pathological features, review the literature on the topic, with special emphasis on the importance of arthroscopy in making the clinical diagnosis, and describe the treatment applied in their case.

Idiopathic scoliosis--new surgical methods or search for the reasons.

Idiopathic scoliosis (IS) is a deformity of the spine whose aetiology is unknown despite of extensive clinical and basic research work. The significance of this disease lies in the consequences of a spine deformity (deformation of the chest, compromise of the cardio-pulmonar function, compression of the neurological elements, severe somatic and psychological sufferings). According to statistical data, one third of the idiopathic scoliotic cases progress and need surgical intervention. Cotrel and Dubousset introduced the three dimensional correction surgical method for the treatment of spine deformities in 1983 (CD method). The authors report on the application of the CD method for the treatment of IS from 1991 to date. After the operation of 36 patients they give an account of good results and report on the modifications of the surgical technique on the basis of their experiences. Aware of the late consequences of the surgical treatment of IS the authors started with the investigation of the aetiology of the disease in order to introduce a causal treatment. As for the aetiological background of IS, data on the role of heritable factors were relevant only. They gave a hint to start with studies aimed at the investigation of genetic determinants of the syndrome. I aberration of chromosome #10 [karyotype: inv(10)(p11q26)]. In one of the cases there was a multiple familial occurrence of the syndrome coupled with the same anomaly of the karyotype. The probands' father and grandfather all had the same pattern of scoliotic deformity and the same aberrant karyotype of chromosome #10 was found both in the proband and his father. Preparation of genomial DNA from peripheral blood of the patients was started. Fragment length polymorphism (RFLP) examination with PCR technique using oligonucleotide primers specific for chromosome #10 and for regulatory genes of left-right body assymetry is underway.

[Results of combined surgical operations in the management of congenital hip dislocation].

The results of 51 different combined operations for the treatment of CDH after the age of two years performed between 1980 and 1989 are presented. The age of the patients at the time of the operation ranged from 2 to 12 (mean 4.5 years. Follow-up was 2-12 (meean 6) years. Preoperatively 19 hips were untreated. Primary surgery included reduction alone in 6 cases, together with femoral osteotomy in 28 cases, reduction combined with Pemberton's operation in 1, and reduction supplemented by both correction techniques in 16 cases. Secondary acetabular correction was later necessary only in 14 cases (27%), thus in 63% of all cases. Radiologycally, the results were of Severin's grade I and II in 64% of the whole series, but in 88% in the 2-3-years-old group. The results in the different surgical groups correlated primarily with the incidence of avascular necrosis and not with the extent of surgery.

[Surgical treatment of hip dislocations in children and damages caused by conservative treatment methods].

For the major requirements of the operative technique and other special problems of operation it is reasonable to discuss among the questions of the reduction of CHD the reoperations and the reconstructive surgery of hips, badly damaged by the conservative treatment, separately. We have analysed the results of 19 own cases with an average follow up of 6.3 years (3-12 years). The average age of the patients was 4.8 years. In 7 patients only conservative treatment was carried out previously, the others were also operated. The Roentgenogram revealed severe ischaemic necrosis in 10 hips. The dislocation could be reduced in every case, to the reduction however it was obligatory to add femoral osteotomy and correction of the acetabulum. The later operation was performed frequently in the second sitting. As a direct result of the operation a state, corresponding to the II. degree of Severin's radiological classification was always reached, in cases of severe ischaemic necrosis however the result later grew worse and at the follow up it corresponded only to the degrees III. and IV. (mediocre, poor). Thus the circulatory damage, suffered during the early treatment determined the late results. This was the reason that the result of the follow up examinations were better in patients in whom early surgery was performed than in patients with forced conservative treatment. The results summarized fall far behind the results of the group with primary surgery of the CHD. Without the operations described these patients would live as limping cripples, with these operations however we have improved their state significantly for the time until TEP can be performed.

Spondylolysis in osteopetrosis.

We report the occurrence of spondylolysis and/or spondylolisthesis of the lumbar vertebrae in five patients with osteopetrosis, four of them having multiple lesions. The case histories indicate that spondylolysis had developed in the pathological bone as a result of increased stress and that it is an acquired lesion.
