[Evaluation of treatment outcome in congenital clubfoot by subtalar release].

This paper presents an analysis of the results of congenital clubfoot treatment by partial or complete subtalar release performed through the Cincinnati approach. Of 116 patients (142 feet) who underwent surgery in the years 1995-1996, 33 (47 feet) came in for final follow-up. The type of primary deformity was defined in only in 36 feet. There were 25 type II deformity and 1 type III deformity. Total subtalar release was performed in 39 feet. Partial subtalar release was performed in 8 feet. During the release procedure, the calcaneo-cuboid joint was not opened, but stabilized with a K-wire. Clinical results were assessed according to the Magone classification. Radiological results were assessed according to the modified criteria of Scientific Committee of the XXI Meeting of the Polish Orthopedic Society held in 1976. Talo-navicular reposition was assessed according to Napiontek. Follow-up time ranged from 40 to 54 months (mean: 48 months). The clinical assessment revealed that the analyzed group as a whole gave 82.2 points (yielding a good result). Very good results were noted in 12 feet (25%), good results in 21 (45%), satisfactory results in 7 (15%) and poor results in 7 (15%). Analysis of radiological results yielded on average 2.5 points (0-7 points). Good results were noted in 45 feet (96%) and satisfactory in 2 feet. A talo-calcaneal index of less than 55 degrees was noted in 23 feet.

Dega's transiliac osteotomy in the treatment of spastic hip subluxation and dislocation in cerebral palsy.

The study presents the long-term results of operative treatment of spastic subluxation and dislocation of hip joints in cerebral palsy children with open reduction and pelvic transiliac osteotomy by Dega. The subjects were 25 patients (30 hips) and the follow-up lasted from 3 to 25 years (average 12 years). Final examinations were carried out after the end of body growth. Detailed analysis covered a patient's function, occurrence and intensity of pain in the hip joint, value of radiological parameters such as angle of centre-edge of the roof after Wiberg (CE), acetabular index (AI), neck-shaft angle (NS) and migration percentage (MP). The final evaluation of radiological results was carried out in accordance with Severin's classification. The clinical and radiological results obtained showed gradual deteriorations in comparison with the early postoperative results (dating from 12 months after surgery). In the final examination, in one patient a recurrent dislocation of the hip joint was diagnosed and subluxation was diagnosed in six patients (23%). Only the values of the CE angle went up (from -16 degrees in the early postoperative examination to 20 degrees in the final assessment), which we consider to be due to the change of sphericity of the head of femur. The remaining radiological parameters did not change significantly: AI from 22 degrees to 23 degrees, MP from 11% to 23%, NS from 133 degrees to 140 degrees. The surgical method presented is currently applied in a modified form, with a wider release within the soft tissues, more radical varusderotation osteotomy and greater shortening of the femur.

[Skew foot--etiology, clinical appearance, management].

Thirty feet in 18 children diagnosed as skew foot (Z-foot, serpentine foot) have been assessed. Following types of deformity have been distinguished: 1. idiopathic congenital (21 feet), 2. congenital, associated with other defects or systemic disease (8 feet), 3. acquired (iatrogenic) after manipulations for club foot treatment (1 foot) and 4. neurogenic, not represented in this study. In the first group minor forefoot adduction that remained after cast treatment was generally accepted by the parents; 7 feet required surgical release. Eight feet were corrected operatively in group 2. In most of the cases palliative procedures were performed due to late turning for surgery of children with systemic disease. In case of type 3 deformity termination of manipulations spontaneously led to the restoration of anatomy in the Chopart joint. According to the authors, surgery, preferably in the first year of life, offers full possibility to regain anatomy and shape of the foot.

[Extracerebral infections of Acanthamoeba spp. in mice].

A variety of Acanthamoeba spp. pathogenic strains were isolated from water pools in the area of Poznań. In many cases amoebae invaded in mice, beside central nervous system (CNS) also lungs, kidney, heart, liver, diaphragm and eyeballs, causing significant changes in these organs. The presence of amoebae outside of CNS was found mainly in the early period of infection. Amoebae isolated from different organs of dead animals did not exhibit any specificity in relation to the organs in following infections.

Evaluation of patella position based on radiologic and ultrasonographic examination: comparison of the diagnostic value.

This study compared radiologic and ultrasonographic methods of evaluation of patella position. The radiologic examination was based on the evaluation of Insall and Salvati's index (I-S index), whereas the ultrasonographic examination was based on the determination of analogous coefficient called the patellar tendon-patellar coefficient (T-P coefficient). The total number of examined knee joints was 55 in 30 patients (13 children, aged 7-16 years and 17 adults aged 17-39 years) with knee pain. Considerable differences of the evaluated parameters were observed in the group of examined children: I-S index, 1.50; T-P coefficient, 1.20; and small differences in the group of adults: 1.17 and 1.32, respectively. Those differences resulted from difficulties with interpretation of the apparent radiologic picture of the knee joint with the patella incompletely ossified. The ultrasonographic picture in both children and adults is a real picture, and the possibilities of its interpretation are independent of the degree of patellar ossification.

Patella position versus length of hamstring muscles in children.

The results of ultrasonographic examinations of the patellar height in the knee joints in children was subjected to analysis. The study aimed at the specification of a norm of patellar height in the developmental age, based on the tendon-patellar coefficient (analogous to the radiologic measurement according to Insall and Salvati). The results of ultrasonographic and clinical examinations of 114 knee joints performed in 57 healthy children were used for the study. The average value of the tendon-patellar coefficient was 1.2 and was independent of age or sex. A statistically significant dependence of the coefficient on the popliteal angle was demonstrated, which indirectly proved the dependence of the coefficient on the length of the hamstrings. In our opinion, the use of ultrasonographic tendon-patellar coefficient allows the differentiation of the so-called physiologic shortening of hamstrings from its pathologic form.
