Abstract
The Wiberg center edge angle (CEA) of 400 hip sonographies among 200 infants, 100 Italians and 100 Brazilians, aged from 15 days to 90 days, whose hip joints were considered normal, from the ultrasonographic point of view (1a and 1b) according to Graf's classification were measured. For the CEA measurements in the studied material, the authors used their own methodology developed for this purpose, which is based on basic geometric concepts and applied by one graphic computer program. In the studied material, the statistical analysis of the results obtained in the measurement of the CEA showed a better conformation of the acetabular roof complex in the Brazilian infants compared with the Italian.

Abstract
A proposta deste estudo foi a aplicação de um protocolo de avaliação e tratamento desenvolvido no Serviço de Terapia da Mão do Setor de Terapia Ocupacional da Disciplina de Fisiatria do Departamento de Ortopedia e Traumatologia da Universidade Federal de São Paulo, destinado a pacientes portadores da Doença de Kienböck e submetidos a técnica cirúrgica de ressecção da fileira proximal do carpo. O protocolo de avaliação foi aplicado em 16 pacientes que foram avaliados no pré e pós-tratamento, considerando-se a dor, perímetro do punho, força muscular, amplitude articular do antebraço e punho e a capacidade funcional. Considerou-se também alguns referenciais subjetivos, no que se refere à satisfação pessoal do paciente quanto ao tratamento. Os resultados mostraram que o protocolo de tratamento aplicado foi eficaz na redução da dor, no aumento do arco de movimento da pronação e supinação do antebraço, abdução e adução do punho e favoreceu a melhora da capacidade funcional da mão afetada. Na avaliação subjetiva 90% dos pacientes tratados em nosso protocolo estavam satisfeitos com a sua recuperação.

Abstract
Fourteen boys (56%) and 11 girls (44%) 4 to 17 years of age (mean, 12.2 years) who had osteosarcoma and open epiphyseal plates were studied. A possible correlation between transepiphyseal spread of osteosarcoma and radiologic and histopathologic findings was investigated. Epiphyseal plate invasion was detected radiologically in only 11 patients (44%), whereas histopathologic examination showed transepiphyseal extension in 21 patients (84%). The authors conclude that the epiphyseal plate is not a barrier against tumor growth and strongly recommend that limb salvage surgery preserving the epiphysis be planned carefully.

Abstract
This article describes the measurement of the Wiberg center edge angle in infants under 3 months using sonographic images of their hips. In the literature review, there was no reference of the application of this angle in this particular age group. Thus, a methodology has been developed based upon the fact that, at this age, the acetabular roof constitutes a large portion of hyaline cartilage. In this way, it was concluded that it was not possible to apply the original Wiberg method since the center of the femoral head can be only estimated and not accurately determined in plain radiography. For this present study, 400 hips of 200 infants were analyzed. All these hips were classified as type 1a or 1b, according to Graf. The sonographic images were transferred to a Pentium computer through a video Spigot interface. The images were analyzed by software specially developed for this purpose. Since ultrasonography allows the exact recognition of the anatomical elements of the hip joint in young children, software provided the acetabular cartilaginous roof angle that corresponds to the center edge angle in adults. The authors believe that this method will be helpful in the early detection of morphological alterations in the hip joint.

Abstract
Wiberg's center-edge (CE) angle was measured in 104 patients with slipped capital femoral epiphysis (SCFE) to determine whether it correlates with a deeper acetabulum. Initially, the radiographs of 45 pre- and mild slip patients (group I) were measured using the contour of the femoral head to determine the head center (point C) as described by Wiberg's original article and, alternatively, using the acetabular line (Visser's method). In addition, the radiographs of 59 patients with moderate and severe slip (group II) were measured in both ways. The measurements were not statistically different between both methods and between the two groups. In 78 unilateral slips, the Mann-Whitney test did not show statistical differences between the normal side and the affected hip (p > 0.05). The Wiberg's CE angle of 58 patients was compared with that of a group control of the same age, gender, and race. The Wiberg's CE angle was significantly higher in patients with SCFE (p < 0.05), the same being true when comparing the white and nonwhite patients separately (p < 0.05 and p < 0.05, respectively). Theories involving biomechanical stress in the adolescent hip can explain the majority of slips occurring in an otherwise healthy child. The femoral head with a better coverage yields more shearing stress across the epiphyseal line. This, associated with hormonal disorders, trauma, or another deleterious factor, can progress to its failure.

Abstract
The Madelung deformity can result in pain and decreased function of the wrist and hand. None of the surgical techniques available has been shown consistently to improve grip strength, range of movement or relieve pain. In this prospective study we have treated 18 patients with the Madelung deformity (25 wrists) by wedge subtraction osteotomy of the radius and shortening of the ulna. Our results show statistically significant improvement in grip strength and range of movement of the wrist and forearm. Pain improved in 80% of the patients and 88% were satisfied with the appearance. One patient had a wound infection and another developed reflex sympathetic dystrophy. Two had some recurrence due to continued growth of the ulna and it is recommended that the procedure be delayed until skeletal maturity, or else combined with epiphysiodesis of the ulna.

Abstract
From a sample of 1,500 individuals belonging to 442 migrant nuclear families from northeastern Brazil, information on the interphalangial mobility was obtained: (a) the grades of extension of both the right and left thumbs and (b) the angle (in degrees) formed by the distant and proximal phalanx of the thumb. The first principal component of these variables was estimated and called "extensibility." A negative association of extensibility and age, as well as with inbreeding, was detected. Complex segregation analysis was applied to extensibility and both a multigenic mechanism and an extra transmissible component were detected. Mendelian inheritance was rejected, while a model with multifactorial inheritance, together with a factor that is inherited with a transmission probability different from 1/2 (tau = 0.63), was not rejected. These findings were supported by path analysis, which showed an important biologic inheritance (h2 = 0.675) and the existence of a small but significant cultural component (c2 = 0.003). The observed "inbreeding" effect, therefore, could not be attributed to a genetic mechanism and probably is the effect of concomitant environmental variability.

Abstract
PURPOSE To analyze the composite tissue vascularized allotransplantation post operative complications and to identify factors associated with agents toxicity. METHOD The study was done across a strong histocompatibility barrier using 39 Brown-Norway rats as donors and 78 Fischer 344 as hindlimb allotransplantation recipients treated with cyclosporine and RS-61443. RESULTS 1 (1/78: 1.28%) was eliminated owing to thrombosis; 2 (2/78: 2.56%) owing to enteritis; 1 (1/78: 1.28%) owing to autophagia and 8 (8/78: 10.42%) died owing to undiscovered cause. CONCLUSION Among 78 (78/78: 100%) rat limb vascularized allotransplantations, 12 (15.5%) rats died or were eliminated because of acute postoperative complications that were not related to rejection, to immunosuppressive toxicity or to opportunistic infection.

Abstract
Composite tissue allotransplantations would contribute to the reconstructions of the congenital, traumatic and tumors deformities. PURPOSE--The aim of this study is to prevent or inhibit the rejection in limb vascularized allotransplantation; decrease the toxicity of available immunosuppressive agents; determine whether combination subtherapeutic doses of CsA +RS-61443 will have an additive immunosuppressive effect. METHODS--Five groups were studied, using Brown-Norway limb donors and Fischer 344 recipient rats: group A Untreated autograft controls; group B Untreated allograft controls; group C Allografts: CsA 1.5 mg/kg/d SQ; group D Allograft: RS-61443 15 mg/kg/d; group E Allograft: combination CsA + RS-61443. RESULTS--The results were the following concerning the rejection: Group A animals displayed no rejection clinically (0%). All the skin biopsies obtained were devoid of rejection (grade 0). Group B animal developed rejection at 10-13 days post-transplantation. Skin biopsies confirmed the epidermal necrosis (grade 4). Group C animals developed rejection in 55%. Group D animals developed rejection in 94%. In contrast, Group E animals had 96% rejection-free survival up to POD 172 thus far. CONCLUSION--Combination subtherapeutic doses of CsA + RS-61443 was effective in preventing acute rejection of limb allografts and had an additive immunosuppressive effect because of the agents immunosuppressive synergistic effect.

Abstract
Twenty-one cervical spines were collected from fresh cadavers (12 male, nine female), their ages ranging from 10 to 90 years (mean 49.47). After removing muscle debris from the spines, they were mounted and tested on a device to passively reproduce the main movements of the spine. The degree of motion in flexion-extension and lateral bending significantly decreased from group A (ages 10-49 years) to group B (51-90 years) (p < 0.005) and was directly correlated with the amount of cervical spine degenerative alterations. The incidence of these alterations, classified according to Lysell (1969), was highest at C5-6. On the testing machine, dynamic angiography of the vertebral artery showed an impingement with extrinsic compression of the vessels in four of 28 successful injections. The histologic serial sections of the uncus showed a characteristic pattern of ossification-deformation: a newly formed cartilaginous tissue tipping the apex of the uncus, forming a double protruding contour of the apex, rapidly ossifying, and appearing to deform outward together with the disk degeneration and consequently decreasing in height.

Abstract
The inclination of the joint line after supracondylar osteotomy of the femur for valgus deformity was studied in 22 patients and 26 knees. The patients (4 males and 18 females) were 17 to 77 years old (mean, 49.5 years). The obliquity of the joint line was measured in positive degrees (medial inclination) and negative degrees (lateral inclination). Mean obliquity was +3.1 degrees in the preoperative study and -2.0 degrees in the post-operative study. Significant horizontality of the joint line was obtained when the two periods were compared (mean, 5.0 degrees).
