[Diagnosis and therapy of chronic rupture of the fibular ligament in children].
74 children with ruptures of lateral ligaments of the ankle were treated surgically between 1979 to 1986. In ten cases we found chronical ligament changes. In these cases periostal flap modified after Kuner was performed. The follow up of our patients showed good results in all, thus we could show that the periostal flap was effective. As the functional conservative ligament rupture therapy increases the periostal flap plastic in the case of children with chronical ligament changes is indicated.

[Severe injuries of the cervical spine in childhood, an interdisciplinary consideration].
Since 1976 in the department of pediatric surgery in Heidelberg we treated five fractures of the cervical spine with luxation, three patients demonstrated a high spinal lesion with tetraplegia. During the past five years eight subluxations were hospitalised. In this paper we relate the various injury mechanisms and fracture forms; especially the typical lesions of the altanto-axial region are discussed. The importance of modern imaging techniques, including NMR, as well as the age- and situation-dependent therapy are detailed. Based on a case report on a four year old boy with upper cervical spine lesion and tetraplegia medical nursing and logistic problems are discussed. Incentives of intensive care albeit limited, in pediatric surgical and pediatric anaesthesiological departments, not specialised in the management of tetraplegia, are pointed out.

[Disorders of vascularization following fracture of the ankle joint in children].
In the Department of Paediatric Surgery of the University of the Heidelberg, 64 children were admitted during five years to the hospital after an ankle fracture. 12 children showed a typical fracture of the growth plate (v. Laer). All 12 were not older than 12 years. The problem of this typical form of fracture is that even careful accurate treatment may be followed by growth problems of the tibial malleolus. A microangiographic postmortem study using plastinated shetts (v. Hagens) showed a normal distribution of vascularity of the ankle joint. The vascular damage after fracture and the damage of the local vascularity in the area at the growth plate after surgical treatment are comparable.

[Surgical protocol and intraoperative considerations in interventions on the testis].
The surgical treatment of incompletely descended of the testes depends on the type of the undescended testis, the age of the patient, and the time of treatment. In a few years' time new techniques of autotransplantation may solve the problem of repositioning the testes in the scrotum. Exact knowledge of possible malformation of the testes and epididymis is essential for the paediatric surgeon. Torsion of one testicle with possible autoimmune impact involving the healthy testicle requires immediate exploratory surgery and treatment according to age. Paediatric carcinoma of the testes is rather rare, whereas treatment and prognosis vary with the histological type. Accurate classification and cooperation with a centre for paediatric oncology are essential.

[Follicular ileitis (Golden syndrome). Apropos of 2 cases].
We report on two cases with the seldom diagnosis of papillary lymphoid hyperplasia. In both cases the children were boys in the primary school age. The admission was performed due to rectal bleeding, abdominal colics and vomiting. Intraoperatively we found papillary changes in the terminal ileum. Suggestions to intra-operative management and literature comparison are given in this study.

[Cantrell's syndrome].
Congenital diaphragmatic hernia is associated with a high mortality, especially when combined with other defects. The unusual repeated combination of the same congenital abnormalities by a number of patients and the fact that during embryonic life these organs develop from the mesoderm implies the existence of a specific syndrome. This article summarises the available clinical data and reports on three cases with Cantrell's syndrome, showing different pattern of congenital defects such as: 1) supraumbilical abdominal wall defects; 2) a defect of the lower sternum; 3) a deficiency of the anterior diaphragm; 4) a defect in the diaphragmatic pericardium; 5) congenital intracardiac defects.

[Lichen sclerosis et atrophicus as a cause of acquired phimosis--circumcision as a preventive procedure against penis cancer?].
From January to December 1985, circumcision for acquired phimosis was performed at our department in 140 boys with a median age of 4 3/4 years. The histological examination of the prepuce revealed the existence of lichen sclerosus et atrophicus (LSA) in 6 cases, e.g. 4.3% of all circumcisions performed. The striking frequency of this chronic inflammatory epithelial change and the often cited connection between the existence of LSA and the development of penile cancer during adulthood as well as the well-known tendency towards the incidence of recurrent phimosis in LSA patients support the claim for total circumcision in these cases.

[Gastrointestinal perforations in neonatal surgery].
From 1970 until 1987 we treated 69 newborns with gastro-intestinal perforations. Immediate measures in form of laparotomy were undoubtedly necessary. Regarding our casuistic the authors present the clinical findings, necessary preoperative diagnostic measures and intra-operative and postoperative treatment. The localisation and the origin of the perforation are pointed out. The most frequent localisation was the small bowel (58%), followed by the colon (35%). Etiologically we found extensive NEC, atresias, meconium ileus and Hirschsprung's disease. In 4 cases iatrogenic rectum perforations, in 3 cases spontaneous gastric and duodenal perforations and twice an appendicular perforation were seen. Our operative procedure depends on the localisation, the degree of peritonitis, on intestinal necrosis and trophic alterations of the gut following ileus. In spite of intensive care, the mortality rate is still very high indicated with 33%. Furthermore more than half premature newborns died (18 out of 33). Based on these facts we propose quick diagnostic measures, interdisciplinary cooperation, an emergency operation followed by intensive care to ameliorate the results. Nevertheless we must keep in mind that newborns, who some years ago were condemned to die, nowadays can be operated, thus changing the mortality of gastro-intestinal perforations.

[Intestinal invagination. Analysis of case reports in the last 45 years].
The retrospective study analyses 219 children with intussusception, who were treated in the Dpt. of Pediatric Surgery, university of Heidelberg between 1942 and 1986. The patients were divided into three groups. The mortality of the first group (1942-1966) was 20%. Since 1966, however, no patient with intussusception was lost. Recent diagnosis advances with ultrasonography allowed early diagnosis and at the same time the complication rate dropped from 34 (group 2, 1967-1981) to 11% (group 3, 1981-1986). Simultaneously the intestinal resection rate was reduced. The developments in diagnosis and therapy during the last 45 years, based on the analyses of the three groups, are discussed in detail with the literature.

[Disorders of vascularization in para-epiphyseal groove humeral fractures and their clinical significance for the growing skeleton].
We analysed retrospectively 50 humerus fractures in the vicinity of elbow joint and 40 fractures of the proximal humerus with respect to possible injuries of the vessel pattern of the epiphyseal plate. The normal vessel pattern of the epiphyseal plate was examined postmortem on 8 foetus and newborns up to 6 months. We plastinated the affected regions and could compare symmetry of the vessel pattern in the epiphyseal plates as well as therapeutic consequences, especially after injuries of the elbow joint. Vascular disturbances in the case of young children, i.e. by fractures of the lateral oder medial condyle are undoubtedly seen. A fish-tail deformity can be a complication. By older children with mature epiphyseal plate we could not register any complications. In such cases we are interested in restoring the joint stability by refixation.

[Peculiarities of juvenile vertebral fractures and dislocations of the cervical vertebrae].
In addition to diagnostic and therapeutic problems of the bony spine injuries in childhood, questions of the participation of the growth plate arise and indicate the following treatment. In the last decade we treated 23 spine injuries, resulting after fall from height. Most of the cases showed single to multiple compression fractures of the anterior spine followed in a descending frequence by the lateral compression fractures, the disconnection ot the epiphyseal plate of the axis and the actual luxation fractures with injury of the stratum germinativum. In contrast to the prognostic favourable impression fractures with a spontaneous correction, luxation fractures with or without paraplegia must be repositionned and stabilized.

[Delivery planning and interdisciplinary management of large coccygeal teratomas].
Prenatal sonographic screening and a growing experience of examiners with regard to possible congenital malformations such as large coccygeal teratomas have induced the request for an early interdisciplinary consultation between obstetrician, human geneticist, paediatric surgeon, neonatologist and psychologist. It should aim at a careful information and counselling of the parents with regard to the mode of delivery and possibilities of operative management. The prerequisites for far sighted planning and performance of delivery are demonstrated by the example of large coccygeal teratomas. The availability of equipment, facilities and manpower at the time of delivery guarantees a course of delivery at reduced risk and is, together with the psychological guidance of the parents, a basic element of optimal care for the newborn.

[Fractures and cartilage injuries of the knee joint in children].
In the last decade we treated and followed up 48 children in the Department of Paediatric Surgery in Heidelberg with fractures and cartilaginous injuries of the knee joint. In 13 cases we could see severe osseous injuries localised at the epiphyseal plate. With decreasing frequency, the following conditions occurred: avulsion fractures of the intercondylar eminence, fracture of the tibia head in children, fractures of the patella and avulsions of the tuberositas tibiae. Furthermore, we report about the special problems of foreign bodies incorporated in the knee joints of children, particularly if sewing needles are involved.

[Implantation technic of a peritoneal dialysis catheter in infancy and childhood].
Since 1979 the continuous ambulatory peritoneal dialysis (CAPD) is used even in childhood. Practical management and tolerance of this method over a longer period are dependent on the compatibility of the chosen catheter material, the implantation technique and the exact introduction in catheter care with sac changing. The used variant of the classical Tenckhoff-catheter with spiral end and individually fitted cuffs has proved to be reliable. The left-sided paramedian incision is the preferred operative access. The transrectal position of the catheter guarantees its cranio-caudal course and placement of the spiral in the minor pelvis. The standardisation of surgical procedure in all details is an essential assumption for the improvement of long-term catheter function.

[Lateral ligament ruptures of the upper ankle joint in children].
This report about 44 cases of fibular ligament lesions compares the results of two series of 22 cases, one investigated from 1978 to 1981 and the other from 1981 to 1983. Introduction of a special holding device in 1981 has resulted in more objective diagnostics. To prevent false indications for surgery the displacement under stress need to be compared with the healthy ankle. If there is 8 degrees difference an operation is indicated in children. Following the example of adult traumatology the introduction of a longitudinal epifibular incision and new techniques employed in ligament surgery have clearly improved the results of treatment.

[Fractures in the elbow joint area in childhood and adolescence].
73 cases of elbow joint fractures were treated in our Dep. of Paediatric surgery over a period of 10 years. Most of the fractures in the region of the distal humerus are localized at the ulnar epicondyle and the radial condyle. At the proximal forearm the radial head and the radial collum fractures are dominant in respect to olecranon fractures. Only two cases involved a comminuted fracture of the distal humerus. Due to the fact that only a small number of cases involving a fracture of the radial epicondyle after a luxation of the elbow were registered, it is possible that we paid no attention to this kind of fractures. An early functional therapy in the case of segmental fracture of the radial head must be emphasized among the 11 cases with a conservative treatment. Another 3 cases with a radial head fracture, type Judet III, should be mentioned, because they were treated without reposition but were spontaneously redressed. The operation procedure and the late results by 62 patients are discussed with the results of other examiners. As expected the comminuted fractures of the distal humerus and the radial head had a bad prognosis. Functional relevant dislocations were rare. Only in one case after a conservative treatment of a lateral condyle fracture a development of a valgus position with a pseudarthrosis after a secondary dislocation was observed. In more than 90% of our cases we could achieve a complete anatomical reposition with good to very good functional results.
