A simple modified arthroscopic procedure for fixation of displaced tibial eminence fractures.

SUMMARY: Avulsion fractures of the tibial eminence have been well described in children and adults with an increased in incidence resulting from road traffic and athletic accidents. According to the literature, only surgical treatment is advocated because of the high incidence of the nonunion and instability following conservative treatment. Open reduction can cause some morbidity and, therefore, arthroscopic techniques have been developed. The limitations of the techniques are related to technical difficulty and unstable fixation. We report a simple and effective method of fixation with the following advantages: (1) use of metallic suture for stable fixation, (2) the fixation device is easily removed in the office, (3) there is no need of additional instruments, and (4) the minimal size of the fixation device avoids damage to the anterior cruciate ligament insertion. This technique has been used in a series of 10 consecutive patients treated for avulsion fractures of the tibial spine since 1991, resulting in a high rate of excellent and good results without any case of nonunion fracture or related complication.

Prospects and advantages in the use of cartilage cell cultures for in vivo transplants.

The authors present a critical analysis of the literature in order to evaluate the current prospects and advantages of cartilage cell cultures for in vivo transplants. The analysis is relative to their use or to the treatment of isolated osteochondral lesions of the knee, and it is preceded by an analysis of the methods used in the treatment of this pathology, such as: 1) debridement, 2) abrasion of the subchondral bone, 3) perforations and decortication of the subchondral bone, 4) perichondral transplants. The most significant results obtained for cartilage cell transplants for the repair of focal osteochondral defects in experiments conducted on animals and in successive clinical trials in man, also revealing the complex problems that may lead to a variability in chondrocytary activity, going from an in vitro to an in vivo environment, are presented.

[Evaluation of atopy risk factors during the first year of life. Multicentric study].

The AA studied 406 newborn babies during the 1st year of life in order to verify the correlation between atopy risk factors and the appearance of early symptoms, particularly gastroenteric (GE). The results obtained did not demonstrate a significant difference concerning the blood cord IgE level and subsequent appearance of food allergy symptoms, whereas positive familiarity showed a better correlation. No significant difference was observed between breast--or formula--fed infants, or between those weaned before or after the 5th month of life. The comparison of dietary regimen adopted during the 1st quarter in the asymptomatic and atopic children respectively, demonstrated that the presence of predisposing factors influences the appearance of GE symptoms much more than the diet in itself. An allergologic study, randomly performed by Prick-test in 156 cases and by RAST in 200 cases, showed a prevalent, positive response with RAST technique in symptomatic children.

A new cervical orthosis with multiplanar adjustment.

It is the purpose of this paper to introduce a new cervical orthosis with multiplanar adjustment. Many orthoses are available to the physician today, but all of them may be classified based on function into two groups: 1) orthoses that immobilize the neck in a fixed position; 2) orthoses that immobilize the patient in a position that may be set in the sagittal plane. At present no orthosis are available to immobilize the neck in a position to anything but the sagittal plane. This new orthosis, with four tridimensional swinging posters, allows for immobilization of the neck in the desired position, according to the clinical evaluation performed. This treatment offers advantages in terms of patient compliance and functional results. An alternative model, with increased stability, has especially been planned for the treatment of pathology at C1-C2.

Our experience in the treatment of rheumatoid knee by arthroscopic synovectomy.

The authors present the results obtained in the treatment of rheumatoid knee by arthroscopic synovectomy. A total of 29 knees operated on in 25 patients after a mean follow-up of 38 months based on the Laurin evaluation scale were re-examined. There was significant improvement for pain, synovitis, and overall function (mean values pre- and postoperative 2.07 vs 0.98; 2.14 vs 0.84, 2.37 vs 1.26, respectively); there were no, substantial variations in joint movement (2.47 vs 2.58). By dividing the patients into the 4 Larsen radiographic classes, the worst results were observed in patients in classes 3 and 4. In this series of patients complications of significance were not observed. Thus, we consider arthroscopic synovectomy to be the treatment of choice for rheumatoid knee because of the intrinsic advantages of minimum disease rate, rapid functional recovery, with expectations of results inversely proportional to the stage of progression of the disease.

Our experience in the arthroscopic treatment of fracture-avulsion of the tibial spine.

The authors present their experience in the arthroscopic treatment of fracture-avulsion of the intercondyloid eminence in the adult with a variation in the original method. In fact, an ACUFEX tibial guide is used for reconstruction of the ACL positioning 2 Kirschner wires with hole at the margins of the fragment, successively sliding the metal wire through the hole. Successive traction on the outside of the wires allows the metal wires to be arranged dome-like to stabilize the avulsed fragment. The distal ends of the wires are stabilized with a metal pull-out in the area corresponding to the anteromedial surface of the tibia. In the 10 patients treated by this method, evaluated after a minimum follow-up of 6 months, we obtained overall satisfactory clinical and functional results. There was significant residual ligamentous laxity in 2 patients with no clinical symptoms of instability. Variations in arthroscopic technique described in the literature are analyzed.
