Experimental comparative study with HA, demineralized bone matrix and autogenous bone marrow.","authors":"P Ragni, P Ala-Mononen, T S Lindholm","doi":"","DOIUrl":"","url":null,"abstract":"Numerous materials have been studied and recently used in clinical practice as synthetic bone biosubstitutes to integrate or even replace autogenous bone grafts. This study consisted of an experimental vertebral fusion model in rabbits using porous hydroxyapatite (HA), both alone and in various combinations with demineralized bone matrix (DBM), as a vehicle for the osteoinductive agent (Bone Morphogenetic Protein-BMP), and with autogenous bone marrow (BM), which supplies BMP-sensitive reticular cells. The animals were divided into two main groups on the basis of the physical form of the biomaterial implanted: HA blocks and HA granules, which in turn included several subgroups based on the composition of the implants (HA, HA+DBM, HA+BM, HA+DBM+BM). There were also control groups with no implant or with bone autografts (ACB). Two months after the operation, analysis of the results (radiograph, fusion stability test on dynamic radiographs, histological evaluation) demonstrated the following: clinical and radiographical results of the group implanted with HA blocks were superimposable on those with autogenous bone grafts, especially in the subgroup treated with DBM and BM, while in the group implanted with granules the results were poor, thus indicating the fundamental influence of the physical state of the biomaterial on bone ingrowth. This was then further confirmed by the histological study in the HA block group, whereas the HA granule group showed a certain fibrous reaction around the granules with poor porous bone ingrowth.","PeriodicalId":75955,"journal":{"name":"Italian journal of orthopaedics and traumatology","volume":"19 1","pages":"133-44"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19547524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Surgical treatment of arthritic valgus knee: femoral supracondylar osteotomy or knee replacement?","authors":"M Berruto, M Bianchi, G Laurà","doi":"","DOIUrl":"","url":null,"abstract":"Twenty-two of the 24 patients operated on with femoral supracondylar osteotomy for arthritic valgus knee between 1978 and 1987 were evaluated, comparing the results with those obtained in a similar group of 10 patients with the same disorder treated with knee replacement during the same period. From a functional viewpoint and according to the Hospital for Special Surgery rating scale, the results of the osteotomy were not significantly different from the extremely positive outcome of the knee replacement. However, as far as pain is concerned, only 50% of the osteotomy patients were completely asymptomatic after the operation. In the 50% of the osteotomy patients with post-operative under or over correction of the mechanical axis of the knee, the results were unsatisfactory. Finally, there was only one case of delayed union. In the light of these results, in contrast to what has been said by other authors, femoral osteotomy may be considered a valid alternative to knee replacement in the treatment of arthritic valgus knee in active subjects, less than 65 years old, with a valgus angulation of no more than 15 degrees and Ahlback stage 2 beta arthritis of the lateral compartment. It is, however, a technique which requires extreme precision both in planning and performing the operation.","PeriodicalId":75955,"journal":{"name":"Italian journal of orthopaedics and traumatology","volume":"19 1","pages":"33-41"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19547527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During the period 1980-1989, 85 patients were treated with this method at the Orthopedic Department of the Università Cattolica in Rome. Evaluation of the cases took into account the patient's characteristics (age, sex, weight, height, obesity, previous or concomitant illness, level of autonomy, mental condition, type of fracture, time elapsed before operation and laboratory tests), details of the operation (length, accuracy of reduction and mechanical fixation stability, post-operative hospitalization period and general and local complications) and follow-up evaluation (X-ray examination, functional examination and evaluation of the results). Analysis of the observations showed that, although it induced less surgical trauma, internal fixation by the Ender method did not ensure a stable reduction, particularly with highly comminuted and basicervical fractures. As a result, the elective indication for this method should be restricted to stable intertrochanteric fractures, particularly in patients with a generally poor condition.","PeriodicalId":75955,"journal":{"name":"Italian journal of orthopaedics and traumatology","volume":"19 1","pages":"25-31"},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19547526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"The Elmslie-Trillat procedure for recurrent subluxation of the patella. One to five year follow-up.","authors":"C Conti, M Berruto, M Bianchi","doi":"","DOIUrl":"","url":null,"abstract":"Thirty-four patients who had undergone the Elmslie-Trillat procedure from 1985 to 1989 were examined in order to evaluate the effectiveness of this operation in the treatment of recurrent subluxation of the patella. The result of an increased Q angle accompanied by patella alta, femoral sulcus dysplasia, or vastus medialus obliquus dysplasia was also studied. Only those patients with recurrent subluxation of the patella took part in this study; cases of habitual or permanent dislocation, potential instability, traumatic dislocation, and degenerative arthritis were excluded. The patients were reviewed both clinically and radiographically, and the A.R.P.E.G.E. scoring system was used to evaluate the results. The follow-up period ranged from 1 year to 5 years and 4 months, with an average of 3 years. The overall results were excellent or good in 77% of the cases, as was the subjective knee stability rating in 87% of the cases and the pain rating in 82% of the cases. Recurrence of the subluxation was observed in only one instance. The results were not significantly different when the groups of patients with patella alta and type 1 femoral sulcus dysplasia were considered separately. The results were also excellent in the patients who underwent the Elmslie-Trillat procedure with reconstruction of the vastus medialis obliquus. In conclusion, surgical realignment of the anterior tibial tubercle confirmed its reliability in the treatment of recurrent subluxation of the patella. In cases of patella alta, the authors recommend lowering the anterior tibial tubercle only when the Insall-Burstein index is greater than 1.3. Femoral sulcus-plasty should be performed in cases of type 3 sulcus dysplasia.","PeriodicalId":75955,"journal":{"name":"Italian journal of orthopaedics and traumatology","volume":"18 3","pages":"341-9"},"PeriodicalIF":0.0,"publicationDate":"1992-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12483457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
