[Osteoid Osteoma of the Upper Extremity].

PURPOSE OF THE STUDY Osteoid osteoma (OO) of the upper extremity is a rare pathology representing a major diagnostic challenge. The patients are often times incorrectly treated due to a misdiagnosis and therefore the final management of symptoms is delayed by several months. During this time the pain, which is the main symptom, increases.

[Surgical Treatment for Advanced Rhizarthrosis. Comparison of Results of the Burton-Pellegrini Technique and Trapeziometacarpal Joint Arthroplasty].

Purpose Of The Study: The aim of the study was to compare results of the Burton-Pellegrini trapeziectomy with ligamentoplasty using the flexor carpi radialis tendon with those of trapeziometacarpal joint replacement in the treatment of advanced rhizarthrosis.

Material And Methods: A group of 17 patients, 15 men and two women, underwent trapeziectomy with ligamentoplaty; in 12 of them, the dominant hand was involved. The trapeziometacarpal joint prosthesis Beznoska was implanted in 11 patients (10 men and one woman) with seven dominant and four non-dominant hands.
