No full textClassification and therapy of acquired non-unions [Classificazione delle pseudoartrosi in relazione al loro trattamento]
No full textThe authors propose a new classification of acquired non-unions, based on their etiology rather than their anatomopathological characterization. Therefore they describe five types of non-union: by insufficient or inadequate reduction, by insufficient immobilization, by bone loss, by extensive lesion of soft tissue and by infection. These types significantly differ from one another for pathogenesis and for clinical and anatomopathological characteristics, and require different management; however they cannot be considered strictly separate, but interdependent with some borderline cases in which many of the etiopathogenetic causes are associated. The practical advantage of such classification lies in the fact that the exact knowledge of the causes inhibiting fracture healing represents a guideline for an adequate therapeutic choice
Pseudoarthrosis of the leg treated with perone pro-tibia transposition. Analysis of long-term results [Pseudoartrosi di gamba trattata con perone pro-tibia: Analisi dell'evoluzione a distanza]
No full textABSTRACT: The authors have performed a retrospective study on 25 patients who were treated with perone pro-tibia transposition because of tibial non-union at the Orthopaedic Clinic of Genova University between 1955 and 1985. Eight of these patients have been examined with an average follow-up of 19.5 years: their long-term radiographs have constantly shown valgus deviation of the ankle joint and no morpho-structural modifications of the fibula, in support of the hypothesis that it does not replace the tibia but behaves like the inert bar of an external fixation device
L'impiego della scintigrafia ossea con 99Tc MDP nel monitoraggio delle artroprotesi di ginocchio New Jersey LCS non cementate
No full textThe Authors monitored 21 non cemented New Jersey LCS knee arthroprostheses using serial bone scintigraphy with 99TcMDP 3, 6 and 12 months after the operations and, in some cases, at lateral intervals. A”normal “scintigraphic pattern of well placed and stable implants was identified together with a series of atypical images. The diagnostic and prognostic meaning of the latter were evaluated on the basis of clinical and x-Ray data
The closed treatment of severe malleolar fractures
No full textThe authors studied, with clinical and radiological criteria the results of closed treatment (reduction by manipulation and immobilization in a plaster cast for 7 or 8 weeks) of severe displaced malleolar fractures. Of 145 patients who had suffered an ankle fracture and were treated with closed methods between 1979 and 1989, 78 were reviewed, with an average follow-up of 6.2 years. The main difficulties of closed treatment concerned reduction of the fractures; anatomical reduction was achieved only in 32.4% of the cases, and deterioration of the position achieved often occurred (26.2%). Although some joints healed in a fair position, subjective and objective late results were excellent or good in 77% of the cases, fair in 20.5% and poor in 2.6%. The most common clinical outcome was a slight decrease of the range of motion in the injured ankle, which was found in 68% of the cases. Arthritis developed in 28.2% of the reviewed ankles, both after an initial good reduction as well as after an initial poor reduction. A complete failure of closed treatment occurred in 8.3% of the cases, caused by an interpositioning of soft tissues among bone fragments leading to unsuccessful manipulation or by late deterioration of the initial position of reduction causing healing of the fracture in a poor position (severe talar shift)
Metastasi scheletriche degli arti.
No full textIn the present study the authors analyse the role of surgery in the management of bone metastases of the limbs given that this approach has proved more efficacious than conservative therapies for achieving the remission of pain and a rapid functional recovery. Since it is difficult to make a prognostic judgement of cancer patients, in terms of the cost-benefit ratio, in order to justify the indication for surgery which is not always without risks or technically straightforward, the authors emphasise the importance of performing scintigraphic screening in order to identify and treat prefractured lesions before the development of bone metastases makes appropriate surgical treatment too risky
