The fixation of a distally ruptured ulnar collateral ligament of the MP 1 (Metacarpophalangeal) joint without a portion of ligament which can be sutured or a small bony fragment can be accomplished with a variety of methods, most of which require drillholes through borth cortices and a counter incision as well as the removal of the material at a second stage [1, 11, 13, 15]. The Mitek bone mini anchor (Ethicon-Mitek®) proved to be a reliable and quick alternative [10, 12, 16, 18, 19]. It was successfully used in eleven patients with excellent stability of the reconstructed joint. 相似文献

Inhibitory effect of glycosaminoglycans isolated from peripheral blood granulocytes of patients with chronic myeloleukemia
and normal subjects on increment in colony-forming units of fibroblasts in monolayer cultures of rat bone marrow is determined
by the degree of sulfation of their main component chondroitin-4-sulfate and by increased content of heparan sulfate.

From September 1984 to December 1989, 38 patients of pediatric age with localized bone sarcomas received intraoperative radiotherapy (IORT) as part of a multidisci plinary treatment program. The age ranged from 6 to 21 years. The tumor histologies were 22 osteosarcomas and 16 Ewing's sarcomas. Thirty-four had initial primary disease (90%) and 4 were treated for local recurrence (10%). IORT was used on 32 untreated patients and in 6 previously treated with external beam radiotherapy (EBR). The IORT field included the surgically exposed tumor bed area. Single radiation doses ranging from 10 to 20 Gy were delivered, using 6–20 MeV electron beams. The median follow-up time for the entire group is 25 months (2–65+ months). The projected 5-year disease-free and overall survival rates are 65% and 69%, respectively. One patient developed a local recurrence in each histological group: one chondroblastic osteosarcoma and one cervical Ewing's sarcoma. Six patients died from metastatic progression: 3 initially recurrent tumors and three primary disease cases. Severe neuropathy and soft tissue necrosis were seen in some patients as IORT related complications. IORT is a feasible technique to be integrated in multidisciplinary programs that may promote local control in pediatric and adolescent patients with bone sarcomas. Peripheral nerves are dose-limiting tissue structures for IORT. 相似文献

瘤体骨切除灭活再植治疗四肢长骨巨细胞瘤 总被引:21,自引:0,他引:21
体内刮除及灭活植骨治疗骨巨细胞瘤(GCT)的复发率高。我科从1986年6月~1996年2月治疗四肢长骨GCT24例。随访11个月~8年4个月。其中7例采用局部切刮体内灭活植骨和(或)骨水泥充填治疗。结果1例感染,6例复发,1例恶变后死于肺转移。作者自1991年1月采用瘤体骨切除,离体灭活再植,与骨残端体内灭活相结合,骨缺损采用自家腓、髂骨移植,L-梯形加压钢板(L-TCP)或梯形加压钢板(TCP)固定治疗17例,其中12例保留关节,5例做膝关节融合。本组无菌创口感染1例,1例复发。在保留关节的12例中9例关节功能恢复优良,1例尚可,2例差。充分说明瘤段骨切除体外灭活再植术疗效确实,复发率低。保留关节术式适于关节破坏较轻(<=1/2)者,结合关节残端体内灭活和有效的骨结构重建,有利于恢复关节功能。如关节面累及>1/2,宜做骨关节端切除,灭活再植,下肢宜做关节融合或人工关节置换术。 相似文献

Background : A patient with a solitary pulmonary metastasis who had breast cancer in the past may benefit from pulmonary resection. Methods : Between 1984 and 1996, 17 patients underwent metastatectomy for metastatic breast cancer. There were 15 females and two males whose average age was 59 (range: 40–74 years). The median tumour-free interval after the primary breast-cancer operation was 5.1 years (range: 8 months-18.2 years). Sixteen patients had complete resections, which included six lobectomies and 10 lesser resections. Results : The postoperative mortality was nil and the morbidity rate was 6%. Follow-up was complete in all patients. Recurrent disease developed in four patients and two patients died of their disease. The 5-year survival was 62%. Conclusion : An aggressive surgical approach is warranted in patients with isolated resectable pulmonary metastases from breast cancer. 相似文献

There is abundant data on cancellous bone in the aging human spine, but little relating to the growing vertebral cancellous
bone in childhood and adolescence. The purpose of this study was to map vertebral cancellous bone in a growth and age series
of historic skeletal samples and to make comparisons with data published on recent material. Lumbar vertebral bodies were
collected from 65 skeletons (0–60 years) from a medieval Nubian population. Ethnohistoric information was collected to interpret
conditions that might have influenced bone structure and metabolism. The cancellous bone was studied three dimensionally,
using stereophotography and scanning electron microscopy and morphometrically by performing a semiautomatic structural analysis
on digitized backscattered electron images of polymethacrylate-embedded material. The cancellous bone structure in the children
consisted mainly of a densely packed, uniform network of small rodlike trabeculae. The greatest bone volume fraction with
small, more platelike trabeculae was observed during adolescence. In young adults, larger platelike trabeculae were present
in the central zone and smaller trabeculae in the superior and inferior zones, as described for modern skeletal material.
Structural changes associated with aging were observed much sooner than in modern man. By the estimated age of approximately
50–60 years, the predominant architectural elements were slender rarified rods in both sexes. The ethnohistorical data suggest
that this was essentially a black African population of physically active peasants, not likely to suffer Vitamin D insufficiency
or deficient calcium intake. Thus an earlier onset of the biological age changes in cancellous bone found in modern populations
was probably prevalent.

Anterior lumbar fusion using a hybrid interbody graft 总被引:3,自引:0,他引:3
Summary This is a radiographic report of 40 patients (20 men, 20 women) who underwent anterior lumbar interbody fusions (73 levels)
utilizing a “hybrid” interbody graft composed of femoral cortical allograft (FCA) bone and iliac crest cancellous autograft
bone. The average age at surgery was 38 years (range 17–64 years), and follow-up averaged 1.4 years (range 1.0–2.4 years).
Nineteen of the patients had undergone previous lumbar surgery. Thirty-two patients (63 levels) underwent anterior fusion
combined with some type of posterior fixation, and eight patients (10 levels) had no posterior fixation. Types of posterior
fixation included: for 20 patients (36 levels) Steffee variable screw placement fixation, for 10 patients (23 levels) translaminar
facet screws (TFS), for 1 patient (3 levels) Knodt rods and for 1 patient (1 level) facet screws. Based on the persistence
of lucent lines at the graft-host interface, three patients (one level each) were felt to have non-unions at their latest
follow-ups at 1.4, 1.5 and 2.0 years, respectively. Two of these patients had no posterior fixation, and the other had TFS
fixation. The overall fusion rate was 96% (70 of 73 levels). The fusion rate for all levels treated with posterior fixation
was 98% compared with 75% for those without fixation. Intervertebral disc heights (IVDH) were measured on all films and corrected
for magnification with computer assistance. On average, the IVDH was increased postoperatively but returned to preoperative
values at follow-up. IVDH loss was independent of the type of instrumentation used. No complications arose from the use of
the hybrid graft. Incorporation of the allograft portion of the graft is slow and was felt to be complete in only 7 of the
73 levels at follow-up. We conclude that the hybrid interbody graft technique is a safe and reliable method for performing
anterior lumbar interbody fusions and should be combined with some type of posterior fixation. Long-term follow-up will be
required to assess the behaviour of the allograft until incorporation is complete. 相似文献

We describe a patient with severe combined immunodeficiency and transplacental transfer of maternal T cells who received an unfractionated HLA-identical sibling bone marrow transplant without prior conditioning. He presented prior to transplantation with a dermatitis later diagnosed as mild graft versus host disease. He had a normal absolute lymphocyte count, but proliferative responses to mitogens were very low. Antigens of the noninherited maternal HLA haplotype were detected on his blood lymphocytes. After transplantation, he developed a severe reaction including fever, cutaneous erythema and hepatosplenomegaly. Lymphocytes carrying the noninherited maternal HLA haplotype disappeared from his circulation, and his unprimed mononuclear cells became spontaneously cytotoxic to maternal lymphoblasts. He subsequently developed a lymphocytosis of 69,000/mm3 , diarrhea, elevated transaminases and a worsening rash, necessitating treatment with immunosuppressive agents. Full T-cell engraftment and evidence of B-cell function later ensued and spontaneously cytotoxic lymphocytes against maternal cells disappeared by 47 days post-transplantation. We postulate that the patient's constellation of signs and symptoms after transplantation represented a combination of severe graft versus graft and mild graft versus host reactions. 相似文献
