Free vascularized fibular bone grafts were used in nineteen children, seen consecutively, who had congenital pseudarthrosis of the tibia. The average age was 5.1 years (range, 1.4 to 11.4 years). Sixteen of the patients had been treated with electrical stimulation for at least one year, and the tibia had not united. All but four patients had had at least one previous operative procedure. At an average follow-up of 6.3 years (range, 2.0 to 11.0 years), eighteen (95 per cent) of the nineteen pseudarthroses had healed. The leg-length discrepancy averaged 1.6 centimeters (range, 0 to 4.0 centimeters), but ten tibiae had residual or progressive valgus or anteroposterior malalignment despite bracing. There was minimum morbidity at the donor site. 相似文献

Soluble Fcγ-binding components were detected in gingival fluid from periodontal lesions by incubation with biotinylated human Fcγ fragments. FcγIII receptor was identified by incubation of gingival fluid with monoclonal antibody. Sodium dodecyl sulfate-polyacrylamide gel electophoresis and Western transfer showed that most of the Fcγ-binding components had minimal mobility in a 4–15% gradient gel under nonreducing conditions. Under reducing conditions, the main band of Fcγ-binding components in gingival fluid migrated corresponding to protein A of 49 kDa. The pattern of Fcγ-binding components was similar in serum and gingival fluid except for the observation in gingival fluid of Fcγ-binding components migrating like standard proteins of 19 to 20 kDa, a size that corresponds to the polypeptide part of FcγII receptor and FcγIII receptor. 相似文献

The extracts from 21 medicinal plants commonly used in traditional remedies in Kenya were screened for antiviral activity against wild type 7401H strain herpes simplex virus type 1. The plant extracts exhibited antiviral activity against the virus in the plaque and yield reduction assays. The results reveal that twelve plants may contain constituents that could be exploited for the management of HSV infections. Although the extracts used in these experiments contain a complex matrix of a large number of compounds the results indicate that useful compounds can be isolated for further exploitation. 相似文献

A prospective outcome study was performed of 100 hip fracture patients at an urban medical center in the United States. After
hospitalization 19% were discharged to a rehabilitation facility and 59% were discharged home. At a mean follow-up of 8 months,
81% of patients lived at home, compared to 89% who lived at home prior to the fracture. At follow-up 71% of the patients were
able to walk outside with one cane or no aids at all, and 81% were able to perform basic activities of daily living. Half
of all patients did not require any home assistance at follow-up. Ten patients had died at follow-up. The goal of operatively
treating the patient with a hip fracture is fixation of the fracture with a return to the patient’s pre-fracture functional
ability. This study illustrates that patients with hip fractures can be effectively treated and discharged home or to a short-term
rehabilitation facility with restoration of their pre-fracture functional status.

Résumé Une étude prospective sur le devenir de 100 patients présentant une fracture de la hanche a été faite dans un Centre Médical Urbain des USA. Après l’hospitalisation, 19% des patients sont allés en structure de rééducation et 59% ont regagné leur domicile. A un délai moyen de 8 mois, 81% des patients vivent à domicile alors qu’il y en avait 89% avant la fracture. Au délai d’observation, 71% des patients marchent à l’extérieur avec une canne ou sans aide et 81% sont capables des activités habituelles de la vie quotidienne. La moitié des patients n’ont besoin d’aucune assistance à domicile. 10 patients sont morts. Le but du traitement opératoire des patients présentant une fracture de la hanche est la fixation de la fracture pour permettre un retour au niveau de fonction pré-traumatique. Cette étude confirma la possibilité d’un retour à l’état fonctionnel antérieur avec, aprés le traitement, un retour à domicile ou un court séjour en Centre de réadaptation.

With the proliferation of school screening programs for spinal deformity, attention has been directed to methods of scoliosis evaluation and follow-up that avoid serial x-ray exposure. An historical review of the scoliosis literature prior to the extensive use of x-ray in scoliosis care has demonstrated much that is now being "rediscovered." By 1900, screening for spinal deformity in the schools had been instituted, pertinent findings of the physical examination in patients with scoliosis had been well described, and early natural history information had been obtained regarding the behavior of small curves and curves associated with thoracic lordosis. Recordings of surface contours and rib humps, using inclinometers, lead rulers, and other measuring devices, were used to assess the progression of curves. Low contour braces were widely available. Although our orthopaedic forefathers had many erroneous ideas, a perusal of the early orthopaedic writings from around the turn of the century has shown how little is "new" (other than changes in material and spinal instrumentation techniques) from what was recognized 75 years ago. 相似文献

STUDY DESIGN: The perioperative and postoperative complications associated with harvesting posterior iliac crest bone graft in children were reviewed. A retrospective study was performed and a questionnaire interview conducted. OBJECTIVES: To determine the morbidity associated with posterior iliac crest bone graft in children. SUMMARY OF BACKGROUND DATA: Iliac crest bone is commonly used as a source of bone graft in spine surgery. Although there are multiple reports of complications in adults, there are no reports in children. METHODS: A retrospective chart review was performed of 214 consecutive children who underwent spinal fusion with posterior iliac crest bone graft from 1990 through 1996. An interview was conducted of 87 patients with normal mental status, predominantly those with idiopathic scoliosis with a minimum of 2 years' follow-up (mean, 55 months). RESULTS: The review showed one (0.5%) instance of arterial injury in the sciatic notch. Two (1%) patients had infections, both of which resolved with a single irrigation and débridement. There was one documented instance of sacroiliac penetration that did not cause clinical problems. The chart review showed three (1.4%) instances of continued pain and one (0.5%) of numbness. By contrast to the few reports of pain in the chart review, responses to an interview of 87 patients showed 21 (24%) children reporting pain at the iliac crest site, with 13 (15%) reporting problems with daily activities. The self-reported pain, on a scale of 1 to 10, ranged from 1 to 10 with a mean of 4. Nonsteroidal anti-inflammatory drugs (NSAIDS) were taken by eight (9%) children for pain at the bone graft site. Five (6%) reported skin irritation, and 18 (20%) mentioned numbness surrounding the scar. CONCLUSION: The perioperative rate of complications in iliac crest bone grafting in children is low (2%). The complication of pain (24%) and pain that is severe enough to interfere with daily activity (15%) is significant at a mean follow-up of more than 4 years. The true extent of pain and numbness after posterior iliac crest bone grafting in children was severely underreported in the medical records and may be underrecognized. 相似文献

We evaluated the reproducibility of the Brooker classification for heterotopic ossification (HO) and, based on the results and weaknesses observed, proposed a simplified system with addition of objective criteria. Six observers classified radiographs of 169 total hip arthroplasties, using the Brooker classification and a modified system consisting of i) absence of HO or islands measuring <1 cm in length, ii) islands >1 cm or spurs leaving at least 1 cm between femur and pelvis, and iii) spurs leaving <1 cm between opposing surfaces or bony ankylosis. Reproducibility was calculated using kappa statistics. For the Brooker classification, interobserver kappa averaged 0.43 (range, 0.74-0.18) (poor). Intraobserver kappa averaged 0.74 (fair). For the modified classification, interobserver kappa averaged 0.59 (range, 0.51-0.76) (fair). Intraobserver kappa averaged 0.78 (good). Interobserver differences were significant (P=.0085). Interobserver consistency to detect severe HO (Brooker 3 and 4, or grade C) improved from 52% to 76% with the modified system. The new classification showed adequate interobserver reproducibility, less variability, and improved consistency for classification of significant HO. 相似文献

Severe arthrosis and deformity of the ankle and subtalar joints are debilitating problems that can be difficult to treat. We retrospectively reviewed and functionally assessed 15 patients who had undergone tibiotalocalcaneal fusion with a retrograde intramedullary nail. The procedure had been a salvage procedure for severe arthrosis and deformity of the ankle and subtalar joints. Minimum follow-up was 2 years. Solid fusion was achieved in 14 of 15 patients. Mean time to union was 16.5 weeks. Ankle-Hindfoot Scale scores showed excellent pain relief at union. Subjective gait disturbances were common postoperatively, though patient satisfaction and the return-to-work rate were high (93% and 80%, respectively). The 12 complications included nonunion, malunion, skin problems, plantar pain, infection, and painful hardware. We advocate using a retrograde nail as a salvage technique in complex posttraumatic or postsurgical settings. 相似文献

Valgus osteotomy of the hip is required in a number of orthopedic conditions in children. We present a simplified valgus osteotomy in which a dynamic compression plate is used. This technique has the advantages of using easily available equipment, requiring only one osteotomy, and providing immediate rigid fixation while not violating the proximal femoral physis. We have used this simplified technique for valgus osteotomy in six hips in four children with excellent fixation, good maintenance of correction, and no complications. 相似文献
