[Malignant nerve tumors about 8 cases]

Malignant nerve tumors, currently called malignant peripheral nerve sheath tumors, are uncommun, and represent less than 10 percent of adult soft tissues sarcomas. The authors report in this article a series of 8 cases of malignant nerve tumors and propose an epidemiologic, diagnostic, therapeutic study and the outcome of these tumors

[Treatment od dorsal fracture dislocation of the proximal interphalangeal joint with arthrodesis technic: about 19 cases]

Trojan fracture is an unstable lesion which associate an anterior marginal fracture of the second phalanx base and a dorsal dislocation of the first interphalangeal joint under the influence of the extensor traction. The instability of this lesion is more important when the anterior marginal fragment is big. Various techniques were described, we report our experience using the arthrorise's technique to treat this lesion. The procedure associate a reduction of the fracture and the dislocation using a dorsal pinning. This procedure is simple and allows an early physiotherapy, important for this joint. We used this procedure in 19 Trojan fractures between 1995 and 2002 awl at 3 years follow-up our results based on functional, clinical and radiological criteria were satisfactory

[ chinese flap about 26 cases]

The chinese flap, alsow called antebrachial radial flap is a fascio-cutaneous flap based on the radial artery. Since the description, it opened indisputably a new chapter in plastic surgery. Through a series of 26 cases realized in our service of which 24 pediculed and 2 free flaps, we ware able to confirm it's reliability, and we studied its advantages and the inconveniences. It's a quite simple flap who can gives a good quality of skin supple and thick. The principal inconvenient is that it scarify a main artery of the hand, that is why, we have to think about it before potting its indication, although we had no complication inherent to this taking. The zone donor always keeps an unaesthetic scar at the level of the fore arm; and consequently the indication at the woman most be studied well I Finally to hairy subjects this flap must be avoided in certain locations such as the palm of th hand and the face

[Erysipelas at the upper limb about 3 cases]

Erysipelas is an acute bacterial infection of the dermis and hypodermis generally caused by streptococcus. This affection is rare at the upper limb. The authors report the observation of three patients of the 4[th] and the 7[th] decade presenting an erysipelas at the upper limb having evolved favorably under antibiotic treatment and hospitalisation in two cases. The erysipelas is of clinical diagnosis basing on general and local signs. The portal of entry must be always looked for and treated. It represents with the diabetes, the obesity and the lymphedema a factor of gravity of this pathology

[ traumatic dislocation of the trapezio metacarpal joint about 5 cases]

The high voltage electrical bums cause an exceedingly high rate of morbidity resulting from the massive necrosis of deeper structures often necessitating major limb amputations. The authors report two rare cases of high voltage electrical burns occurring accidentally with a 49 and 19 year old men after an indirect contact with a high voltage line. These high voltage electrical burns caused massive necrosis and extended necrosis m the upper limb requiring the recourse to a disarticulation the shoulder. The indications and the operative techniques used are discussed
