[Reimplantation of the artificial hip joint in girdlestone hips is superior to girdlestone arthroplasty by itself].

AIM: The aim of this work was to compare the functional results of secondary Girdlestone hips with the results of total hip replacement (THR) after a Girdlestone situation. METHODS: 72 patients with THR following a Girdlestone situation and 87 patients with a Girdlestone situation (90 hips) were compared with regard to defined endpoints. RESULTS: THR following a Girdlestone situation provided for significantly higher patient satisfaction (89 % versus 13 %) and hip function (HHS 63 versus 39 points). The groups only marginally differed with regard to the incidence of complications (0.32 versus 0.26 per patient) and the necessity for surgical revision (0.38 versus 0.31 per patient). CONCLUSION: Conversion of Girdlestone hips with THR provided patient satisfaction and functional results superior to secondary Girdlestone hips while the incidence of postoperative complications and revisions were similar for both groups. These differences justify attempts at the conversion of Girdlestone situations with THR, if technically possible, in accordance with the patient's wish and as allowed by his/her general health.

Complete intercostal artery reimplantation using a method of aneurysmoplasty.

We report the case of a 58-year-old woman who underwent repair of a chronic dissecting thoracoabdominal aortic aneurysm. Using a method of aneurysmoplasty under normothermic cardiopulmonary bypass, all intercostal arteries were quickly reperfused, and the spinal cord ischemic time was minimized. No neurological deficits developed in our patient using this method.

[Splenectomy and reimplantation of splenic tissue in children].

161 splenectomies are presented with a morbidity of 14.8% and a total mortality rate of 4.3%. The lethality rate due to severe infections (-3.9%), however, was high and mostly caused by an overwhelming postsplenectomy sepsis, pneumonia or meningitis. 61.5% of the infections were caused by pneumococcus. To drop that high lethality rate after splenectomy we replanted splenic tissue in seven patients. Scintigraphic investigations showed in all cases well vascularised splenic tissue. The immunoglobulins were in a normal range. Howell-Jolly bodies, however, did not disappear in all the patients. From our study as well as from the literature one has to conclude that replanted splenic tissue requires immunologic activity but a reduced capacity for phagocytosis. Therefore, in cases of traumatic injury to the spleen it is necessary to try to preserve as much of the organ as possible either by infrared coagulation, gluing with human fibrinogen or partial splenectomy. If these procedures are impossible a replantation of--50% of the original splenic tissue should be done and several thin homogenised particles replanted intra- or retroperitoneally. Out of that a preoperative vaccination against pneumococcal infection is necessary as well as a postoperative penicillin prophylaxis for about three years.

[Femur head reimplantation in the reconstruction of dysplastic acetabula].

Problems encountered in implanting prostheses in severely dysplastic hip joints are attributable on the one hand to deficient formation of the acetabulum, on the other to restricted medullary space for the shaft. The latter problem may be regarded as largely resolved thanks to the development of special dysplasia shafts adapted to these anatomical conditions. For reliable anchoring of the artificial acetabulum, an adequate lateral and anterior roof covering is required to support the implant. With reference to a study covering 16 patients who underwent surgery over a period of 3.5 years, the authors report on their experience with a surgical procedure in which the removed femoral head is used in the construction of the acetabulum. The surgical technique - which has now been standardized - and the indications are described. The advantages of this procedure are that the use of additional alloplastic material is reduced and that if the acetabulum has to be replaced at some later date a well-developed bony structure is available for fixing the new prosthesis.

Image analysis of chromatin in cells of reimplantation mouse embryos.

Mouse two-celled embryos and blastulae were Feulgen stained and the DNA content of their nuclei was measured with an integrating microdensitometer. The cells considered on the basis of their nuclear DNA content to be in G(1), S, and G(2) phases of the cell cycle were selected and their total chromatin area and chromatin areas at different gray levels were measured by the image analyzing computer, Quantimet. The measurements were aimed at quantitation of several features of the chromatin morphology of cells in different functional states. The total area of chromatin was found to increase, and the mean density of chromatin to decrease, from the G(1) to the G(2) phase of the cell cycle in both two-celled embryos and blastulae. The area of chromatin decreased, and the mean density of chromatin increased, as embryos developed from two-celled to blastula stage. It was concluded that nuclear morphology in preimplantation mouse embryos depends on both the phase of the cell cycle and the stage of development. The method of image analysis described was found to be useful for quantitation of changes in chromatin morphology.

Separate-lung ventilation strategy for reimplantation of esophageal bronchus.

IMPLICATIONS: We describe an original ventilation method designed to optimize lung recruitment and gas exchanges during surgery in a newborn with congenital esophageal atresia and ectopic esophageal implantation of the left mainstem bronchus. This strategy ensured constant adaptation of the mechanical ventilatory regimen to the surgical procedure-linked constraints.

Technique for liposuction fat reimplantation and long-term volume evaluation by magnetic resonance imaging.

Injection with one's own fat tissue remains controversial due to a lack of objective data pertaining to postoperative volume control. Facial defects in a total of 53 patients were repaired using autogenous fat tissue. The fatty tissue was obtained from the lower abdomen, buttocks, or inner portion of the upper thigh and then suspended before injection in a solution of 250 ml Ringer's solution, 50 ml distilled water, and 0.7 ml hyaluronidase. The fatty tissue was collected by a filter integrated within the suction system and subsequently prepared, as follows: (1) Cell detritus, blood constituents, and local anesthetic were flushed away by using a physiological Ringer's solution. (2) The defects were filled by using a finely calibrated, locked injection, whereby the desired amount of fatty tissue could be accurately instilled. (3) Injection was carefully performed directly under the cutis through a large lumen cannula and under close observation to avoid the injection of any fatty tissue intracutaneously. Before the procedure, the augmented areas had been evaluated by using magnetic resonance imaging (in T1-weighted images). Postoperatively, the sites were once again documented for volume at control intervals of 6 days, and 3, 6, 9, and 12 months. The volumes were computer-calculated integrally from the sum of the area of all the layers according to the following formula:v = (d + g).E(ai). Despite the use of hyaluronidase as well as an atraumatic liposuction technique, microscopic examination revealed 40% of the aspirated cells to have defective cell membranes. Without hyaluronidase, this figure rose to 50%. One-year follow-up in 10 patients showed that through the break-down of these damaged cells, a particularly high volume loss of 49% was documentable at 3 months after the procedure. Further follow-up at 6 months showed that average volume decline had risen to a total of 55%, whereas, at 9 months as well as 12 months, no further loss could be detected. Autogenous fat transplantation after liposuction is a procedure only suitable for the repair of small, soft-tissue defects, especially of the face. The individual deposits should not be any larger than 1 ml, whereby intact fat cells are guaranteed sufficient diffusion up to the point of neovascularization. It is essential that the fatty tissue injection be exactly administered subcutaneously. Together with basic clinical observation, magnetic resonance imaging provides an objective evaluation of volume loss with an average error of only 5%.
