[Kirner's deformity. 4 case reports and review of the literature].

Kirner's disease is a rare deformity of the distal phalanx of the little finger, with a combination of camptodactyly and clinodactyly and clinodactyly. A review of the literature and analysis of our cases show that this anomaly appears to result from a unusual insertion of the deep flexor over the growth cartilage. No treatment is required in view of the absence of any clinical and functional symptoms.

[Anorectal traumas by impalement in children. Apropos of 3 cases].

Traumatic impalement is an exceptional cause of anorectal lesions in the child. The clinical diagnosis is sometimes difficult and associated lesions raise the problem of the most appropriate exploratory examination. Based on our experience with three cases, we would emphasize the usefulness of hydrosoluble enema study prudently performed by the surgeon during the preoperative work-up.

[Flaps for covering extensive losses of cutaneous substance on the upper limb. Apropos of 15 cases].

The authors report on their recent experience concerning flap treatment of upper limb complex trauma, based on 15 cases. Proper wound care, and the use of healthy, well vascularised tissues for coverage is of paramount importance for good results, whose quality mostly depends on the severity of initial lesions. The results of this series are encouraging and appear to be a consequence of the great possibilities offered by the cutaneous or muscular flaps used.

[Traumatic atlanto-axial dislocation in children: 7 cases].

Seven cases of atlantoaxial rotatory dislocation in children are reported. The CT scan permitted differentiation of the lesions in all the cases. Analysis of the results has led us to introduce two modifications for Fielding's classification: a distance between the atlas and odontoid of less than 5 mm is normal.

[Characteristics of fractures of the distal part of the clavicle in children].

Fractures of the clavicle are frequent in children and mostly affect the middle third. On the other hand, traumatic fractures of both medial and lateral thirds of the clavicle are rare. The lesions have special characteristics: difficulty in diagnosis for the medial third; risk of callus formation in the absence of surgical reduction of the lateral third.
