Authors reported the results of clinical experiments on the use of Ceftriaxone in the prophylaxis of post operative orthopaedic and traumatological complications in 30 patient. The absence of post operative infection and the good tolerance confirm its usefulness for antibiotic prophylaxis in orthopaedic surgery.

[Involvement of the occipito-atlanto-axial articulation in rheumatoid arthritis]. / L'impegno dell'articolazione occipito-atlanto-assiale nell'artrite reumatoide.

The authors, after reviewing the world bibliography, remember the seriousness, quoad vitam, of the atlanto-axial sub-luxation as a frequent complication of rheumatoid arthritis. They, for such reason, emphasize the importance of a precocious diagnosis, with the systematic research, in patients suffering from rheumatoid arthritis, of the clinical and radiographic signs of such a dreadful complication.

[A case of concurrent subcutaneous injury of the right quadriceps tendon and the left rotular tendon in rheumatoid arthritis]. / Un caso di lesione sottocutanea simultanea del tendine quadricipitale destro e del tendine rotuleo sinistro in artrite reumatoide.

Authors, after briefly remembered the etiopathogenesis, pathological and therapeutic aspects of subcutaneous ruptures of patellar and quadriceps tendons, present one case of bilateral simultaneous lesions in R.A.

[Thalamic fractures of the calcaneus. Indications and osteosynthesis technics]. / Fratture talamiche di calcagno. Indicazioni e tecniche di osteosintesi.

The authors describe their therapeutical attitude as regards the thalamic fractures of heel, and distinguish two basic methods of surgical approach: reducing of thalamus and synthesis with only screws in the simple fractures; reducing of thalamus and restoration of the heel morphology by mtans of plate and screws in the complex fractures. They particularly report the satisfactory results got through the use of Lanzetta's plates, which, allowing a good reducting and a steady synthesis in the complex fractures also, permit an early mobilization.

[Traumatic simultaneous bilateral fracture of the first rib]. / Frattura bilaterale simultanea traumatica della prima costa.

The authors report a very rare case of traumatic simultaneous bilateral fracture of lrst rib with no concomitant lesions of skeleton, internal organs, or vasculo-nervous ones.

[Granular cell myoblastoma (apropos of a case with bilateral localization in the thigh)]. / Mioblastoma granulo-cellulare (A proposito di un caso con localizzazione bilaterale alla coscia.

Granulo-cellular myoblastoma (MGC) is a rare disease, the nature of which is still discussed and uncertain. The authors describe a particular case with bilateral location at thigh in a patient suffering also from pigmental villonodular tenosynovitis (TSVNP) at the right thumb. This observation confirms the absolute benignancy, and supports the theory of the non-neoplastic histogenesis of MGC.

[Bloodless treatment of patellar instability; author's experience]. / Il trattamento incruento nell'instabilita' rotulea; nostra esperienza.

The Authors discuss the cases treated in the Fatebenefratelli Hospital in Erba in the period 1975-80 and propose strengthening of the quadriceps muscle as first treatment of knee cap instability.

[Pigmentous villonodular synovitis affecting the bone (author's transl)]. / Sinoviti vello-nodulari pigmentose con interessamento osseo.

Pigmentous villonodular synovitis (P.V.N.S.) is a rare arthropathy consisting in a hypertrophic-hyperplastic reaction of the synovial membrane in circumscribed or diffused form. Involvement of the bond, found very rarely during the course of this arthropathy, seems to be due to compressive-erosive action of diffusely hyperplastic pathologic tissue and not neoplastic invasion. In this note there is a report on the cases of the "G. Pini" Orthopaedic Institute in Milan: 33 cases of P.V.N.S., of which 5 with bone involvement.

[Our experience in the treatment of septic pseudarthrosis. Recent advances and technical details]. / La nostra esperienza sul trattamento delle pseudo-artrosi settiche. Nuove acquisizioni e dettagli di tecnica.

We felt that it was both necessary and useful to complete what had been said and written on other occasions regarding our cases. This updating paper therefore contains the impressions arising out of expansion of our experience, some details of technique and above all a better designed therapeutic strategy that we feel will be more effective in solving the long-standing polymorphous problem of treatment of septic pseudoarthrosis.

[The treatment of medical fractures of the femoral neck]. / Il trattamento delle fratture mediali del collo del femore.

It is first stressed that medial fractures of the femur neck pose therapeutic and prognostic problems linked above all to biological factors. After reference to the criteria of classification adopted by Linton and Pauwels, the need to adopt fixed parameters in establishing the surgical indication is then asserted. These parameters are the patient's age, understood not only as number of years but also as general and psychic state, and the obliquity of the fracture line or its degree of decomposition. The Authors conclude by establishing four theorectical groups of patients and indicating the treatment they adopted for each group.

[Treatment of supracondyloid fractures of the femur with Judet's bone plate and screws]. / Il trattamento delle fratture sovracondiloidee del femore con la vite-placca di Judet.

Severe fractures of the distal end of the femur, which have become increasingly numerous as a result of the multiplication of road accidents, frequently require surgical treatment. The Authors, updating to 1979 the cases of the "G. Pini" Orthopedic Institute in the field of Judet's screw-plate, document the validity of this means of synthesis as confirmed by the quality of the results.
