Delayed dislocation of radial head following upper radial epiphysial injury.

Injury to the upper radial epiphysis is mainly a radiological diagnosis. Delayed dislocation of the radial head following such injuries, where there is no evidence of primary subluxation or dislocation, has not been recorded in the literature. We have identified three such cases that needed open reduction. As long term results of delayed treatment of dislocation of any joint is not good, we advocate the awareness of this complication and also a longer period of routine follow-up (up to a year) of all upper radial epiphysial injuries, to avoid a catastrophe in an entirely preventable situation.

The value of scintigraphy in hips with slipped capital femoral epiphysis and the value of radiography and MRI after 10 years.

Preoperative bone scintigraphy of the femoral head in 33 hips with slipped capital femoral epiphysis, showed no relation to duration of symptoms or degree of slip. The preoperative uptake was always normal or increased. Two hips had postoperative femoral head uptake below normal, both had complications affecting the vascular supply, resulting in necrosis of the femoral head and severe arthrosis. At follow-up after 10 (5-15) years of 28 hips, no relation could be demonstrated between Adolescent Hip Questionnaire which included clinical data, and radiography or magnetic resonance imaging. We only recommend scintigraphy after complications jeopardizing the vascular supply of the femoral head in slipped capital femoral epiphysis.

Slipped capital femoral epiphysis after septic arthritis of the hip in an adolescent: report of a case.

Septic arthritis of the hip must be managed promptly to avoid the serious complications associated with the condition. In the case reported here, the diagnosis was delayed and was complicated by a slipped capital femoral epiphysis. The patient, an adolescent boy previously in good health, presented with a 2-week history of hip pain and systemic illness. Septic arthritis was diagnosed and was managed by incision and drainage and antibiotic therapy. Two weeks later he presented with a subcutaneous abscess and a slipped capital femoral epiphysis, which was pinned in situ. There was a 2.5-cm leg-length discrepancy. Avascular necrosis of the femoral head subsequently developed leaving the boy with a permanent disability.

Fractures of the proximal humeral epiphysis.

Displacements of the proximal humeral epiphysis at the epiphyseal plate result from extension injuries. The configuration of the epiphyseal plate and the thickness of the periosteum surrounding the epiphysis make slight to moderate displacements relatively stable injuries, which can be treated successfully with external support. In patients with more severe displacement, flexion, abduction, and slight external rotation of the distal fragment bring the metaphysis into alignment with the proximal fragment, correcting the anterior angulation. The thick periosteal sleeve attached to the physis through which the metaphysis tears out anteriorly has great potential for remodeling the persistant bowing that remains after healing of the fracture. Although shortening and residual angulation results from closed treatment are almost always good and open surgery is rarely indicated.

Osteonecrosis of the femoral head associated with slipped capital femoral epiphysis.

We performed a retrospective analysis of 212 patients (299 hips) with slipped capital femoral epiphysis (SCFE) over a 9-year period to assess the incidence of osteonecrosis of the femoral head. Risk factors for the occurrence of osteonecrosis and the influence of treatment on the development of osteonecrosis were determined. Osteonecrosis occurred in 4 hips with unstable SCFE (4/27) and did not occur in hips with stable SCFE (0/272). The proportion of hips in which osteonecrosis developed was significantly higher among the unstable hips (4/27 vs. 0/272, p < 0.0001). Among those with an unstable hip, younger age at presentation was a predictor of a poorer outcome. Magnitude of the slip, magnitude of reduction, and chronicity of the slip were not predictive of a poorer outcome in the unstable group. In situ fixation of the minimally or moderately displaced "unstable" SCFE demonstrated a favorable outcome. We have identified the hip at risk as an unstable SCFE. The classification of hips as unstable if the epiphysis is displaced from the metaphysis or if the patient is unable to walk is most useful in predicting a hip at risk for osteonecrosis.

The value of early postoperative bone scan in slipped capital femoral epiphysis.

The purpose of this study was to evaluate the sensitivity and predictive value of early postoperative bone scan for detection of avascular necrosis (AVN) of the femoral head after surgical treatment of slipped capital femoral epiphysis. We reviewed records of 49 patients (64 hips) operated on between 1980 and 1997 with a mean follow-up of 3 years. Sixty-one out of 64 hips went through an early postoperative bone scan. The three hips that developed AVN showed significant loss of radionuclide uptake. There were neither false-positive or false-negative cases in this series. Early postoperative bone scan has an excellent sensitivity and predictive value for detection of AVN after surgical treatment of slipped capital femoral epiphysis.

Slipped capital femoral epiphysis associated with peripheral osteoarticular tuberculosis.

We report a case of slipped capital femoral epiphysis that developed associated with a peripheral osteoarticular tuberculosis lesion located at the proximal metaphysis of the femur in contact with the growth plate in a 12-year-old boy. Multiple factors have been involved in slipped capital femoral epiphysis pathogenesis, but we believe an osteoarticular tuberculosis lesion is not a common finding as a possible etiological factor causing weakness of the growth plate and, therefore, the femoral head displacement.

Dislocation of the proximal femoral epiphysis in acetabular fractures.

Acetabular fractures are often associated with dislocation of the proximal femoral epiphysis. The dislocation may be of three types, based on the type of fracture to which it is associated: anterior, central, posterior. In anterior and in central dislocation epiphyseal necrosis of the proximal femur has never been observed, while in posterior dislocation necrosis has been observed in 23% of cases. Diagnosis of posterior dislocation is of essential importance so that it may be reduced immediately, decreasing the risk of necrosis. The authors report a review of 192 fractures of the acetabulum to which dislocation of the femoral epiphysis was associated, treated between 1980 and 1996 at the IIIrd Division of the Rizzoli Orthopaedic Institute.

An operation for partial closure of an epiphysial plate in children, and its experimental basis.

In two cases of partial closure of epiphysial causing angular deformity, one of a finger and one of the lower end of a femur, the deformities were corrected by growth after resection of a small peripheral bone bridge and its replacement with a free transplant of fat. This procedure has a firm basis on experimental work. Thus, when part of a growth plate in the rabbit is destroyed but the formation of a bone bridge uniting epiphysis and metaphysis is prevented, the destroyed part is replaced by regeneration of cartilage from the adjacent parts of the plate. Moreover, it has been proved in rabbits that when a bone bridge is induced and later resected and replaced with fat, recurrence of the bridge can be prevented and subsequent growth may correct the deformity.

[Studies on the distribution of glycogen phosphorylase and succinate dehydrogenase in the humeral epiphysis of various-age rats].

In the chondrocytes of the humerus epiphysis of newborn and 8-, 30- and 60-day-old albino rats, glycogen phosphorylase and succinate dehydrogenase activity was found. The enzymatic pattern of glycogen phosphorylase and succinate dehydrogenase diverges significantly within the age groups. In the chondrocytes of cartilage epiphysis of newborn and 8-day-old animals glycogen phosphorylase is distinctly present. The enzyme is reduced in 30- and 60-day-old rats. The initial moderate reactions of succinate dehydrogenase in the column cartilage and in the proximal hypertrophic cells demonstrate an additional activity from 30-day-old animals. The osteoblasts of the metaphysis demonstrated a strong reaction.

[Study of the correlations between the volumes of the hypophysis, the epiphysis and the subfornical organ to the somatic weight and the volume of the hypothalamus in rodents].

The correlations between volume of the hypophysis, of the epiphysis and of the subfornical organ to body weight and volume of the hypothalamus were studied on 193 rodents belonging to 41 species. Concerning the volume of the hypophyseal lobes the regression slopes of Rodentia occupy an intermediate position between those of Isectivora and Prosimians studied by BAUCHOT. The volume of the epiphysis increases more rapidly with the weight of the body than that of the hypophyseal lobes, the volume of the subfornical organ increases on the contrary more slowly.

[Morphofunctional state of epiphysis in relatively wild and domesticated silver-black foxes during pregnancy].

Morphological indices of changes in the epiphysis activity during pregnancy are analyzed in relatively wild and domesticated silver-black foxes. The diameter of light actively functioning nuclei of pinealocytes increased most significantly and reliably in the end of pregnancy and, at the same time, the area of their surface decreased. These signs witness an enhanced protein synthesis. Unlike other stages of ontogenesis, the degree and dynamics of epiphysis activity during the period of pregnancy were similar in animals of both groups.

Abduction injuries of the distal femoral epiphysis.

Based on a follow-up study of 15 distal femoral epiphyseal fractures, the following conclusions are drawn: Closed reduction with cross pinning of the distal femoral epiphysis provided slightly better results and prevented loss of reduction; angulation deformity, requiring corrective surgery occurred in four patients, two of whom had initial anatomical reductions; significant leg length inequality was not seen; abduction injuries of the distal femoral epiphysis are not uncommon in teenage football players.

The treatment of slipped upper femoral epiphysis by fibular grafting.

Fixation and early fusion of slipped upper femoral epiphysis can be achieved by the use of a fibular graft inserted through a lateral approach under X-ray control. Experience of the method in 18 hips has shown that fusion of the epiphysis had occurred in all cases by 19 weeks after operation whereas in 6 out of 13 cases treated with Moore's pins fusion was delayed beyond 6 months. The clinical and radiological results were comparable to those in cases treated with Moore's pins. There were no complications associated with the donor area. The method is suitable for the treatment of all stages of the condition with the exception of the most extreme degrees of chronic slip.

[Consideration of the legitimacy for connecting the opposite femoral head and neck in juvenile slipped capital femoral epiphysis].

Forty seven patients were treated because of slipping of the capital femoral epiphysis, in 23 patients (48.9%) both hips were involved. In one third of these cases both hips were diagnosed at the same time, in one third second hip was diagnosed from 6 to 24 months later, in one third only late diagnosis of juvenile symptom free--thus the late diagnosis. In 18 hips slipping was less than 30 degrees, in 5 hips more than 30 degrees. On the basis of authors own experience and review of literature the conclusion was made to fix with K--wires epiphysis of the opposite hip as a prophylaxis against slipping.

[The importance of Dunn's procedure in the treatment of slipped femoral epiphysis].

The slipped upper femoral epiphysis (SUFE) is a condition also known as 'coxa vara' of the adolescent, in which lesions of the growth plate are responsible for the development of sudden or gradual displacement of the femoral head. The disease is most frequent in the 10-15 years' age group, usually in boys who also have endocrine disorders. Both acute and chronic presentations are described. The clinical symptoms and especially the X-Ray features are diagnostic. Treatment options include orthopedic (conservative) measures or surgery, depending on several conditions, such as: the clinical picture, the degree of the femoral displacement, and the age of the patient. The chronic, long-lasting cases are generally associated with poor results. The paper presents our experience in using the Dunn's procedure in 7 chronic cases of slipped upper femoral epiphysis in children. It appears that surgery by using Dunn's procedure is an effective treatment in patients with SUFE.

Acute primary hematogenous osteomyelitis of the epiphysis: report of two cases.

Acute primary infection of the epiphysis is uncommon. We present 2 cases of acute osteomyelitis of the distal femoral epiphysis. They were not diagnosed until 10 days and 3 weeks, respectively, after the onset of symptoms. The epiphyseal infection spread into the knee joint, and surgical debridement was performed. The majority of reported cases in the medical literature are of bacterial etiology, and the most common pathogen is Staphylococcus aureus. We report a rare case which was infected by Salmonella enteritidis. Prompt diagnosis and early treatment are required to prevent further destruction and growth disturbance.

The mechano-biology of the epiphysis of the long bones as revealed by photoelastic models.

Stress contours have been generated in photoelastic models simulating cartilaginous and bony epiphyses. According to the findings, the secondary centre of ossification is formed in areas of the cartilaginous epiphysis shown to have reduced mechanical stress. The bony epiphysis appears to have been developed as a more mechanically efficient structure.
