Extra-articular subtalar arthrodesis. A long-term follow-up in patients with cerebral palsy.

Of 23 children (35 feet) with cerebral palsy who had undergone a Grice extra-articular subtalar arthrodesis for a valgus hindfoot between 1976 and 1981, we reviewed 17 (26 feet), at a mean of 20 years (17 years 3 months to 22 years 4 months) after operation. Seven were quadriplegic, eight spastic diplegic, and two hemiplegic. They were all able to walk at the time of operation. Thirteen patients (20 feet) were pleased with the Grice procedure, 13 had no pain and 15 (23 feet) were still able to walk. The clinical results were satisfactory for most feet. Radiography showed that the results had been maintained over time but 14 feet developed a mean ankle valgus of 11 degrees (6 to 18) with a compensatory hindfoot varus in 12 feet. No deformity of the talus or arthritis of adjacent joints was noted. The Grice procedure gives good long-term results in children with cerebral palsy.

Role of laparoscopy in vaginal malformation.

BACKGROUND: The aim of this study was to assess the role of laparoscopy in the management of vaginal malformations in children, a subject not often discussed in the literature. METHODS: Between 1980 and 2002, we treated 22 children for vaginal malformations. Two main patient populations were distinguished: younger children with asymptomatic hymenal imperforation and hydrocolpos, and adolescents with hematocolpos. A third of the malformations were identified on systematic clinic examination, a third on the basis of abdominal pain, and a third due to various other symptoms. Nine of the girls had associated malformations of the uterus, external genital organs, or urinary tract. Eight patients underwent laparoscopy, either to look for endometriosis in cases of hematocolpos, to make an accurate determination of malformations in cases where clinical and paraclinical methods failed, or to manage an abnormality. RESULTS: Eleven laparoscopic procedures were performed in eight patients. Three diagnostic laparoscopies enabled us to determine the exact nature of the malformations. One newborn underwent two laparoscopic procedures to treat peritoneal fibrous bands that had caused repeated episodes of obstruction. Six patients underwent exploratory laparoscopy to look for endometriosis, but none was found. CONCLUSION: Laparoscopy is not applied systematically in the management of any malformation, but it can be useful when complementary exams fail to make an accurate diagnosis of the anomaly or for the management of the rare complication of adhesions and bands. When used to search for endometriosis, MRI detects ~50% of lesions, but laparoscopy is certainly still appropriate for that purpose. However, the optimal timing of the procedure still needs to be established.

[Varicella complicated with necrotizing fasciitis caused by group A hemolytic Streptococcus].

UNLABELLED: Chickenpox has a high risk of invasive group A streptococcal disease and necroziting fasciitis. CASE REPORT: A five-year-old girl, during chickenpox treated with ibuprofen, developed sepsis and edematous and necrotic lesions of the pelvis and the abdominal wall. The child improved with surgical treatment and adjunction of clindamycin to the antibiotic therapy. CONCLUSION: We review the optimal medical and surgical treatment of necrotizing fasciitis and discuss the role of chickenpox and non steroidal antiinflammatory agents in this disease.

Toe-walking in children younger than six years with cerebral palsy. The contribution of serial corrective casts.

Our aim in this retrospective study was to analyse the value of serial corrective casts in the management of toe-walking in children aged less than six years with cerebral palsy. A total of 20 children (10 hemiplegic and 10 diplegic) had elongation of the triceps surae by serial casting at a mean age of four years and one month. The mean passive dorsiflexion of the foot with the knee in extension was 3 degrees (-10 to +5) and 12 degrees (0 to +15) with the knee in flexion. After removal of the cast passive dorsiflexion was 20 degrees (+10 to +30) with the knee in extension, and 28 (+10 to +35) with the knee in flexion. At a mean follow-up of 3.08 years (2.08 to 4.92), passive dorsiflexion was 9 degrees (-10 to +20) with the knee in extension and 18 degrees (0 to +30) with the knee in flexion. Serial corrective casts are useful for the treatment of equinus in young children as the procedure is simple and the results are at least equal to those of other non-operative techniques. It is a safe alternative to surgical procedures especially in young children. If the equinus recurs operation can be undertaken on a tendon which is not scarred.

[Neonatal curettage of giant congenital nevi].

OBJECTIVE: All agree upon the need for early treatment of giant congenital nevi, basically because of the risk of melanoma degeneration, estimated at about 5 p. 100. Another reason is the cosmetic, psychological and social impact of such nevi. The aim of this study was to assess neonatal curettage of giant congenital nevi as an alternative to classical surgery. PATIENTS AND METHODS: Between 1996 and 1999, the curettage technique was used in 14 newborns with giant congenital nevi. Three nevi were located on the scalp, 4 on lower limbs and 7 on the trunk with a jacket configuration in 1 case and a cape configuration in 4. RESULTS: Curettage achieved 70-95 p. 100 clearing of the giant nevi in 10 of the 14 children. Four of the children developed hypertrophic scar tissue which resolved with time. Secondary hair growth was observed in 5 cases. Outcome was better when the curettage was performed very early (before 2 weeks of life). DISCUSSION: Curettage is a surface technique proposed when surgical excision cannot be performed because the surface is too large or the localization is incompatible with surgery. Curettage is a simple low-cost technique which provides particularly satisfactory cosmetic results for very extensive giant congenital nevi. The risk of malignant transformation is greatly reduced although not totally. Regular clinical surveillance under conditions greatly improved by the clearing should help reduce the risk.

Tracheobronchial ruptures from blunt thoracic trauma in children.

BACKGROUND/PURPOSE: Tracheobronchial ruptures in blunt thoracic trauma in children are rare. The aim of this study was to suggest the means of an early diagnosis and a conservative management as often as possible. METHODS: Sixteen cases of tracheobronchial ruptures by blunt thoracic trauma were observed over 26 years in 9 regional pediatric centers. RESULTS: There were 12 boys and 4 girls, from ages 1 hour to 17 years. Nine children presented with associated lesions. Fibroscopy established the following diagnosis: 8 tracheal wounds and 8 bronchial wounds. Six children were operated on within 18 hours (on average) after installation of a thoracic drainage. Two lobectomies, 3 ideal tracheal sutures, and 1 bronchial suture were performed. Seven children were treated exclusively by thoracic drainage. Two of them were intubated through the lesion, leading to a transitory endoprothesis accompanied or not by an external thoracic drainage. One infant recovered spontaneously. There were no deaths in this series. Two recurrent postoperative nerve injuries were noted, one of which was a transitory spontaneously resolutive scar bud and one a granuloma treated by laser. Three times, a stenosis occurred after a conservative management. Two were operated on. CONCLUSIONS: Tracheobronchial ruptures in children are rare. An early fibroscopy holds an important place in the approach of this pathology. Treatment is variable, based on thoracic lesions, their tolerance by the child, and associated lesions. Surgery is not the only therapy because conservative treatment by simple thoracic drainage or lesion intubation has proved effective.

Predicting the outcome of adductor tenotomy.

This study reviewed 57 hips in 30 children (18 girls and 12 boys) with cerebral palsy who had undergone an adductor tenotomy alone or in combination with an anterior obturator neurectomy (23 hips). Results were evaluated by the Reimers migration percentage (MP). The hips were split into three groups: group A (12 hips) a preoperative MP of less than 20%, group B (25 hips) between 20 and 40%, and group C (20 hips) more than 40%. The mean age at the time of surgery was 6 years and 1 month (range: 2.5-13 years). The mean period of review was 6 years and 3 months (2-20 years). The results were considered as "good" when radiographs at the longest follow-up showed a decrease of > 10% of the MP, as "bad" when they showed an increase of > 10%, and as "stable" when the MPs varied less than 10%. At the latest review of group A, 11 were stable (92%) and 1 was bad. In group B, 12 were stable (48%), 7 were good (28%), and 6 were bad (24%). In group C, 7 were stable (35%), and 13 were bad (65%). The preoperative migration percentage provided to be the only predictor of outcome. Age at the time of surgery had no constant significant effect on the outcome, neither had the addition of an anterior neurectomy.

[Continent urinary diversion using a tubulized sigmoid segment. An alternative to trans-appendicular diversion].

OBJECTIVE: The authors propose the use of a sigmoid tube reimplanted submucosally in the bladder and brought out onto the skin in the midline or in the umbilicus as a method of continent urinary diversion allowing urinary catheterization several times a day when the appendix cannot be used. MATERIALS AND METHODS: Three adolescents with neurogenic bladder were treated according to this procedure; the summit of the sigmoid colon loop was selected to form a continent tube from a segment 4 cm wide, opened along its antimesenteric border and sutured longitudinally. RESULTS: The postoperative course was uneventful in all 3 cases. The cystostomy was continent. Catheterizations were easily performed. CONCLUSION: Creation of a sigmoid tube is an alternative to the use of the appendix for continent urinary diversion according to Mitrofanoff's procedure. This technique can always be performed due to the proximity of the sigmoid colon and bladder, which is not always the case with the appendix. This tube is richly vascularized and presents the advantage of a very narrow mesocolon which does not interfere with creation of the intravesical submucosal tunnel.

[Surgical management of malignant bone tumors in the child. Saint-Etienne Hospital experience, apropos of 17 cases].

From 1980 to 1997, seventeen children were treated for malignant bone tumors in the Department of Paediatric Surgery of the Saint-Etienne Hospital, with an average follow-up of 6 years and 3 months (2M-17Y). The histologic diagnoses were osteosarcomas (12 cases) and Ewing's sarcomas (5 cases). All children were treated surgically. For the 12 lower limb tumors, the techniques used were prosthetic replacement in 7 cases (associated with bone allograft in 3 cases), amputation in 3 cases and isolated bone allograft in 2 cases. The two ilium tumors were treated by resection and reconstruction with autologous bone graft. A single resection was performed for the shoulder-blade Ewing's tumors and a prosthesis for the 2 proximal humerus tumors. Six children died during follow-up. The authors stress that carcinologic resection is a priority before functional results. They insist on the mechanical failures of implants and on the difficulties of reoperations.

[Intra-thoracic costal sites of osteogenic exostoses in the child].

PURPOSE OF THE STUDY: The authors report 2 cases of internal costal exostosis in children. OBSERVATIONS: Case 1: A 15-year-old boy with hereditary multiple exostosis presented for chest pain. Radiograph and CT scan showed an internal rib exostosis. It was removed by thoracotomy. Eighteen months later, the child was painfree. Case 2: An-11-year old boy presented with fever and a headache. A chest radiograph showed an image of pulmonary opacity interpreted as a pneumonia. The child was admitted for antibiotic therapy. Two months later, X-ray lesion persisted and a CT-scan was obtained. It showed a solitary costal internal exostosis which was removed by thoracotomy. At 12 months follow-up, he was asymptomatic. DISCUSSION: Internal costal exostosis can induce some complications such as hemothorax, diaphragmatic or pericardic wounds. In case of symptomatic exostosis, the authors recommend a surgical removal to avoid severe complications. If the exostosis is asymptomatic, abstention can be recommend. As a matter of fact, hemothorax, for instance, can occur even due to a round and smooth exostosis without any history of trauma.

[Treatment of blunt splenic trauma in children].

UNLABELLED: The conservative management of blunt splenic trauma in children has been generally accepted for about twenty years, in order to avoid serious post-splenectomy infectious complications. The objective of this study was to evaluate the results of conservative management. PATIENTS AND METHODS: 21 cases of blunt splenic trauma were treated between 1 January 1991 and 31 December 1995. Eleven cases were isolated and 10 were associated with other visceral, musculoskeletal or head injuries. The lesion consisted of subcapsular or intraparenchymal haematoma in 8 cases and ruptured spleen in 13 cases. All children were initially managed conservatively, except in the case of unstable haemodynamic parameters after resuscitation, perforated viscus or secondary complication. RESULTS: Emergency surgery for blunt splenic trauma was never required over this 5-year period. Four children required secondary surgery, 2 for left renal lesion, 1 for pancreatic pseudocyst and 1 for epidermoid cyst of the spleen discovered incidentally at the time of the trauma (partial splenectomy). No associated bowel perforations were observed. Four children were transfused, 3 for an associated visceral lesion and only once because of ruptured spleen. The mean length of hospital stay was 18.2 days in the case of isolated rupture and 28.7 days for a ruptured spleen associated with other lesions. No immediate or long-term complications were observed with a mean follow-up of 6 months. CONCLUSION: Conservative management of blunt splenic trauma is possible under good conditions of security and total splenectomy was never required. The blood transfusion rate was very low.

[Muscular lengthening of the triceps by successive casts in children with cerebral palsy].

PURPOSE OF THE STUDY: Twenty children with cerebral palsy who underwent elongation of the triceps surae using successive plaster-casts (28 short triceps) were reviewed. This study was retrospective. MATERIAL AND METHODS: Among the eighteen children, 10 were hemiplegic, 8 were diplegic and 2 were spastic quadriparetic. All of them except one were ambulatory children. The authors describe their elongation technique by plaster-casts and the treatment they lead. The mean age at time of elongation was 4 years and 6 months (range 2 years 4 months to 8 years). The passive dorsiflexion of the foot before elongation was of 0 degree (range -20 degrees to +10 degrees) knee in extension, and of 5 degrees (range -15 degrees to +15 degrees) knee in flexion. RESULTS: The passive dorsiflexion of the foot after elongation was of 23 degrees (range +10 degrees to +30 degrees) knee in extension, and of 27 degrees (range +10 degrees to +35 degrees) knee in flexion. One major complication was noted: the persistence of a varus foot in child after elongation. 24 elongations were reviewed with a mean follow-up of 21 months (range 12 months to 30 months). The passive dorsiflexion of the foot was of 10 degrees (range 0 degree to +20 degrees) knee in extension and of 17 degrees (range -5 degrees to +25 degrees) knee in flexion. DISCUSSION: Compared to different procedures (surgical lengthening, botulinum-A toxin) elongation by successive plaster-casts is a quick, safe, complication-free, and simple technique, whose results are equivalent. Even if recurrence of equinus is probable, a surgical procedure of lengthening could be made on an operative-free tendon. CONCLUSION: Elongation of the triceps surae muscle by successive plaster-casts constitutes a safe alternative technique compared to surgical procedure.
