PURPOSE OF THE STUDY: Arthroscopic assisted treatment of tibial plateau fractures may reduce morbidity compared to open articular surgery, but bony fixation is necessarily percutaneous and minimal. The purpose of our study was not only to assess immediate results but also long term functional and anatomic results after arthroscopic treatment of tibial plateau fractures, with special reference to radiographical Results:

MATERIAL AND METHODS: seventy patients (mean age 47 years, range 18 to 72 years, 43 men, 27 women) were arthroscopically assisted treated for a fresh tibial plateau fracture. According to Schatzker classification, there was 20 type I, 27 type II, 18 type III and 5 type IV. The fixation device was: Kirchner wire in Schatzker I, percutaneous cannulated screw in Schatzker II,III,IV, and bone cement filing of the fracture site in 1 case. In 32 cases, where bone loss was significant. we use autologous bone graft, in 18 cases SRS. There were 15 meniscal injuries: 3 underwent arthroscopic suture, 8 had partial meniscectomy and 4 sub subtotal meniscectomy. We also diagnosticated 7 lesions of the medial pivot 6 ACL, 1 PCL : all were left in place. Al patients in the first post-operatory day start passive rehabilitation with kinetech All cases were suitable for immediate post op follow up. 19 were reviewed at long term. A clinical (Hospital for Special Surgery) and radiographical examination were done with an average follow-up of 46.7 months.

RESULTS: There were no complications except two immediate compartimental syndromes that stopped the arthroscopic treatment. Passive motion of the knee started at 1 day postop with no pain. Mean flexion at 3 months was 130 degrees. At revision, the average score was: 93 for Schatker I, 91 for Schatker II, 87 for Schatker III, 86 for Schatker IV. In eight cases we found early signs of osteoarthritis. There were no secondary bony depression or significant valgus deformity on X-rays.

CONCLUSION: Arthroscopic management of tibial plateau fractures allows a complete articular screening. Rapid rehabilitation, short hospital stay, and low rate of complications reduce morbidity. The long term results are as good as those with open surgical technique for the types of fracture that we have treated (type III and IV). A minimal, percutaneous osteosynthesis which was the only possibility under arthroscopic control, did not modify the anatomical Results:

Elbow dislocations are difficult to treat because of the high incidence of short- (vascular and neurological lesions) and long-term (decreased range of motion and instability) complications. We report the results obtained in 20 elbow dislocations treated with hinged cast tutorisation or hinged external fixator.

We treated 20 patients with an average age of 45 years (range 16– 62 years). The average follow-up was 7 months (range 5–18 months). We divided the patients into two groups: patients treated by a hinged tutor for 4 weeks (group A), patients treated by hinged external fixator, removed after 5 weeks (group B). All the patients were evaluated clinically using the “Mayo elbow performance score” after 3 weeks, 1 month and 1 year.

Results were excellent in six elbows and good in 14; none of the patients had an insufficient or poor score. We observed deficit in prono-supination in three patients and deficit in flexion and extension in six patients; three patients complained of epicondylar pain when carrying something. At the end of the treatment none of the patients complained of instability.

According to our data normal function can be restored after early mobilisation. Our experience suggests that the most important aspect in the choice of treatment is the evaluation of joint stability after reduction. The results obtained with the external fixator are very good in terms of restoring function; the incidence of complications is very low and was equally distributed between the two groups.
