    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.

    ABSTRACT: The author presents two cases in which pseudoarthrosis of the ulnar diaphysis resulted in dislocation of the head of the radius. The pathogenesis of this secondary dislocation is discussed. The cause of anterior Monteggia fractures is not yet clear. Various explanations have been put forward: direct action of a force (Speed and Boyd, 1940), forced pronation (Evans, 1949) and hyperextension with strong contraction of the biceps (Wright, 1963). This work presents two cases of Monteggia fracture characterized by a "slow" fracture mechanism. The biomechanical aspects are discussed.

    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.

    ABSTRACT: The authors present a preliminary study on the treatment of intertrochanteric fractures with a reinforced 95 degrees blade-plate, devised and used at the II Orthopedic Dept. of the University of Milan, in cooperation with the Milan Polytechnic. They discuss the indications and clinical-radiographic findings of the first 14 cases operated on, with a mean follow up of two years.

    ABSTRACT: The authors analyse the method used between 1983 and 1990 in 161 patients with chronic anterior laxity of the knee treated by 162 ligament reconstructions utilizing synthetic ligament prostheses. Tearing of the prosthetic ligament is the most feared and frequent complication. This may be due to technical error, wear of the material or, to a lesser extent, new trauma. With a follow-up of up to 80 months, the number of tears seems excessively high. This means that artificial ligaments cannot today be considered a satisfactory surgical technique. The considerable technical improvements in autologous reconstructive surgery make the biological approach preferable even today.

    ABSTRACT: Twelve cases of intervertebral discitis following lumbar discectomy were evaluated and ESR was assessed in 70 patients operated on and without evidence of postoperative infection. Six of the intervertebral discitis patients were studied retrospectively and 6 prospectively. In the retrospective group, patients reported that symptoms appeared on average 15 days after the operation. Antibiotic treatment generally began 31 days after the operation and lasted 62 days; symptoms regressed after 3.9 months. All patients showed long-term radiographic vertebral changes and osteolysis in the cases treated later. In the prospective group, the first symptoms appeared on average 5 days after the operation, treatment started after 8 days and lasted 41 days. Symptoms regressed after 1.8 months. There were only 3 cases of vertebral radiographic changes. In both groups, ESR was always more than 70. The most useful diagnostic imaging tests were conventional tomography and MRI. Needle biopsy had no effect on the length of treatment. In 14% of patients without infective complications, ESR increased noticeably a week after the operation but, in contrast to the intervertebral discitis patients, it did not then continue to increase. Close post-operative observation permitted early detection of intervertebral discitis. Early and high-dose antibiotic treatment, even if unspecific, can resolve this infection in a few weeks.

    ABSTRACT: A retrospective study was carried out to evaluate the results of intramedullary fixation by Ender nailing in the treatment of intertrochanteric fractures. 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.

    ABSTRACT: A comparative analysis of the radiographic results of 111 screw sockets (65 tapered and 46 hemispherical cup sectors) was made to evaluate both their behaviour over a period of time and the validity of their use today. The follow-up was performed on average 42 months after the implant. Overall survivorship shows a high risk of failure during the fourth year and a greatly increased rate of failure after the sixth year. Comparison of the survival curves of the two types of acetabular component revealed no significant differences. The two types considered were, however, of different sizes: the implanted taper sockets were on average 6.6 mm larger than the comparable hemispherical cup sector acetabular components, thus involving a greater loss of acetabular bone.

    ABSTRACT: Preservation of the femoral neck in hip arthroplasty creates a particular biomechanical situation which is clearly different from what is found even after partial neck removal. The femoral neck consists in fact of a "cylinder of cortical bone" that can be used as the "base" for anchoring the stem to the femur, in contrast to the press-fit procedure or other solutions. The mechanical and biological advantages are as follows: 1) Primary triplanar stem stability, in particular rotational stability. Rotational movements of the stem are blocked by the tough lateral cortical cylinder of the neck. Resistance to varus-valgus stress and collapse is also increased vertically and frontally. 2) Proximal cortical fixation. Primary fixation of the stem is provided by the neck cortex, whereas its mid-distal part is merely held by the metaphyseal cancellous bone and the tip is undersized with respect to the medullary canal. 3) Stress loads distributed along physiological lines of stress. Retention of the neck permits preservation of the trabecular systems, along which the stress is distributed towards the diaphysis and the greater trochanter. 4) Elasticity of the bone-prosthesis system. Most of the stem is contained within the metaphyseal cancellous bone that lies between the prosthesis and the cortical bone, creating a bone-prosthesis module with variable and integrated elasticity. 5) Preservation of the bone-stock. The amount of residual bone following implant of the prosthesis increases, not only because of the presence of the femoral neck, but also as a result of the preservation of most of the metaphyseal cancellous bone. There is therefore greater bone-ingrowth, which is also favoured by the fewer changes in the endosteal blood supply. 6) Prosthesis revision is simpler, since the stem can easily be removed and a second neck resection performed. Our clinical and experimental studies, together with those of Freeman et al., confirm that the femoral neck is present for a long time after implant. Finally, we report a study of 200 prostheses with a follow-up of 1 to 6 years, demonstrating neck reabsorption in only 1% of the cases.
