[Pathophysiology of complex regional pain syndrome [CRPS] type 1]

If the pathophysiology of complex regional pain syndrome [CRPS] type 1 remains controversial, most authors agree on a combination in varying proportions, a sensitization of peripheral nerves. To describe the state of advances in the physiopathology of complex regional pain syndrome type 1. Bibliographic research and literature review performed by referring to databases [Medline, Science Direct]. The physiopathology of complex regional pain syndrometype 1 remains still poorly understood and controversial. Several arguments demonstrated both peripheral [inflammation, abnormal sympathetic ...] and central [neurological and cognitive] mechanisms. A better knowledge of the physiopathology of complex pain syndrome type 1 is necessary in order to adapt efficient curative therapy or to a better prevention of this syndrome

[ results of anterior cruciate ligament reconstrution by bone - patellar tendon - bone technique. a series of 40 cases]

We reviewed retrospectively 40 patients treated surgically for rupture of anterior cruciate ligament. The technique used was arthroscopy bone patellar tendon reconstruction. The mean age of patients was 27 years. The operative delay was 27.2 months in average. Functional and anatomic result was evaluated with a mean follow up of 24 months. 80% of patients were classified IKDC A or B. Sports activity was resumed after 6.6 months in average. Results depented meniscus lesions and operative delay. Reconstruction of anterior cruciate ligament with bone patellar tendon bone is a reliable technique. Operative delay should be as short as possible to prevent meniscus lesion and aggravation of laxity
