237 patients with a non-traumatic disease of the hip requiring total hip replacement entered a multicentre trial. Treatments were allocated at random in a double-blind manner: 113 patients received 5000 IU of standard heparin t.d.s.; 124 patients received enoxaparin 40 mg once a day. Treatment lasted from 10 to 15 days until bilateral ascending phlebography of the lower limbs (BAPLL) was performed. Its effectiveness was assessed by the results of BAPLL, by evaluation of the risk of bleeding on examination of the surgical wound, by the units of blood required for perfusion and by daily blood count and differential. BAPLL was performed in 228 patients: 15 phlebographies (12.5 p. 100) were positive in the 120 assessed patients of the enoxaparin group, while 27 (25 p. 100) were positive in the 108 assessed patients of the standard heparin group (p = 0.014). Proximal deep vein thrombosis was significantly (p = 0.03) less frequent in the enoxaparin group (7.5 p. 100) than in the standard heparin group (18.5 p. 100). Pulmonary embolism was observed in a patient on standard heparin. The units of blood required for perfusion were significantly (p = 0.03) smaller in the enoxaparin group (3.37 +/- 1.81 U) than in the standard heparin group (3.84 +/- 1.70 U). Thus, one single subcutaneous injection of enoxaparin 40 mg daily was significantly more effective and safer than standard heparin 5000 IU t.d.s. in the prevention of deep vein thrombosis after total hip replacement.

[The stage of articular destruction in the rheumatoid hand].

Function incapacitation of the hand in rheumatoid arthritis was studied on 33 patients (54 hands). 35 were operated on. All cases had reached the stage of articular destructions. The authors emphasize the importance of preserved proximal inter-phalangeal joint for digito-palmar pinch. Thumb unstability was not severely disabling as long as the other digits were normal. However, when it was associated with hyperextension deformities of the other fingers, the hand became useless. Surgical indications in rheumatoid hand were detailed. The importance of restoring thumb function was pointed out.

[Cysts of the external meniscus].

The authors have treated 20 cases of cyst of the laternal meniscus of the knee. In most of the cases, the diagnosis was made late. The clinical, radiological and pathological features are described and the etiological factors are discussed. Complete meniscectomy relieved the symptoms in 17 cases.
