Luxation transscaphocapitale antélunaire du carpe : une nouvelle variété, une nouvelle approche

Carpal antelunar dislocation and Fenton syndrome: Extremely rare association

“…In the case reported by Wodecki et al, 2 the capitatum fracture requires a posterior check. This approach allowed the reduction and osteosynthesis of the scaphoid satisfactorly.…”

“…The association of these two entities remains anecdotal (3 cases described). 2 The authors report a case of antelunar trans scapho capital dislocation, with the capitatum head in place. 2 Since the description by Fenton in 1956, 11 less than 30 cases of scaphocapital fracture have been found in the literature.…”

“…2 The authors report a case of antelunar trans scapho capital dislocation, with the capitatum head in place. 2 Since the description by Fenton in 1956, 11 less than 30 cases of scaphocapital fracture have been found in the literature. In a multicenter study of 166 perilunar dislocations, Herzberg found only 4 cases of retrolunar trans-scapho dislocation associated with a fracture of the capitatum head and 5 other cases of antelunar dislocation.…”

“…The development of mini-screws in recent years has greatly facilitated this technique. 2 After reduction, Wesely 17 recommends starting with the osteosynthesis of the capitatum to obtain a good quality carpal neocondyle. The excision of the avulsed fragment of the capitatum head formerly used is no longer required, the repositioning of the fragment with osteosynthesis having made it possible to obtain completely satisfactory results, thus justifying the principle of conservative treatment.…”

“…The anterior approach is most often recommended. 2 In the case of Fenton syndrome (scaphocapital fracture), the head of the capitatum is generally turned 180 (Vance et al, 3 Boisgard et al, 4 Masmejean et al 5 ). The authors report a case of antelunar trans scapho capital dislocation, with the capitatum head in place.…”
