RESUMO
INTRODUCTION: Since Kanavel in 1905, knowledge of phlegmon of flexor tendon sheaths of the fingers have evolved over the twentieth century. This serious infection is 20% of infections of the hand and may have adverse consequences for the function of the finger and even beyond, of the hand. Amputation is always a risk. Frequently face this type of infection, we conducted a retrospective study and made an inventory of knowledge in order to consolidate and improve the overall care. MATERIALS & METHODS: The study was retrospective and cross, focused on 120 patients operated on at Hand Surgery Unit, during 4 years. Inclusion criteria were primary or secondary infection of the sheath of the flexor tendons of the fingers.The evaluation focused on clinical and paraclinical perioperative parameters. At last follow, digital mobility (Total Active Motion), the functional score of QuickDASH and the socio-professional consequences were evaluated. RESULTS: The mean age was 40 years, with a male predominance. The hospital stay was 17 days on average (3 days to 80 days). From the classification of Michon, as amended by Sokolow, we found 60 Stage I, 48 stage II, 12 stage III. The Total Active Motion was respectively 240 °, 140 °, 40 °. QuickDASH scores were respectively 20, 56 and 90 out of 100. The time for return to work was 1 month for stage I, 4 months for stage II and 12 months for stage III. DISCUSSION: The long-term functional outcome was generally poor, with stiffness or digital amputation. The poor prognostic factors were: the initial advanced stage of infection, infection beta-haemolytic Streptococcus group A, and delayed surgical management. Smoking was identified as a new risk factor in this disease, as well as diabetes or immunodeficiency. This study confirmed the predominance of Staphylococcus, and scalability of the infection depending on the mode of contamination, and / or type of germ that is to say, scalability schedule for ß-hemolytic streptococci group A chronic and scalability for intracellular bacteria (mycobacteria). CONCLUSION: Any suspicion of flexor hand tenosynovitis should lead to an emergency surgical exploration, not primary antibiotics prescription!
