Traumatic haemarthrosis of the knee.

We have investigated a prospective series of 100 acute traumatic haemarthroses of the knee in a general non-athletic population. All the patients had normal radiographs and an aspiration which confirmed the haemarthrosis, before undergoing ligament testing and an arthroscopic examination under anaesthesia. Only one patient had no serious pathology; in the other 99 a total of 193 lesions were recorded. Thirty knees had only one isolated lesion, 69 had combined lesions. This study confirms the serious nature of an acute traumatic haemarthrosis of the knee, even in non-athletic patients.

The Müller acetabular support ring. A preliminary review of indications and clinical results.

A series of 41 total hip arthroplasties with acetabular reinforcement by a Müller support ring is reviewed. The postoperative management was the same as that used in conventional cemented total hip arthroplasty. The overall clinical results and the radiological findings were most satisfactory after one to six years. Of the 30 hips available for functional assessment using the Merle d'Aubigné scale, 16 were excellent, 10 good, 2 fair, 1 poor and 1 bad. These results indicate that, regardless of the primary disorder, the Müller support ring has been helpful when dealing with severe osteoporosis, an acetabular floor lined by bone which does not allow adequate penetration of methyl methacrylate, a small acetabulum needing a small polyethylene socket and localised destruction of the acetabular roof or of the anterior or posterior acetabular pillar. A good result can only be guaranteed if the ring makes a perfect fit with the reamed acetabular cavity.

The use of computerised tomographs in the diagnosis of thoracolumbar injury.

This paper presents four patients with injuries to the thoracolumbar spine assessed by computerised tomography. This technique enabled an easy, quick and accurate diagnosis to be made, avoiding dangerous manipulation of the patient. The scans were analysed using the anatomical classification of Louis to evaluate the instability of the lesions. Control CT scans were used to monitor progress and to provide an accurate prognosis within acceptable limits of irradiation.

Comparative radiologic study of the influence of ankle joint bandages on ankle stability.

A comparative radiologic study was carried out to test the stabilizing value of ankle strapping and taping on unstable tibiotalar joints. Unstable ankle joints of 51 athletes were examined without bandages, with strapping, and with taping before and after an activity program. The use of taping proved to give the greatest decrease of the talar tilt (TT) angle. This improvement was greater, even after activity, than the stabilization obtained by strapping before any activity.

Static and dynamic roentgenographic analysis of ankle stability in braced and nonbraced stable and functionally unstable ankles.

Patients suffering from functional ankle instability were selected based on a structured interview. Talar tilt was measured using supine ankle stress roentgenographs and standing talar tilt was measured using erect ankle stress roentgenographs. A digital roentgenocinematographic analysis of a 50 degrees ankle sprain simulation was performed to measure dynamic talar tilt and inversion distance between two video images (inversion speed). A significant decrease in pathologic supine talar tilt in unstable ankles was found in the braced compared with the nonbraced situation (talar tilt = 13.1 degrees versus 4.8 degrees with brace). The talar tilt with the brace after activity was still significantly lower than the initial value without the brace. The standing talar tilt of unstable ankles was shown to be significantly lower with the orthosis than without (standing talar tilt = 16.6 degrees versus 12.0 degrees with brace). Roentgenocinematographic evaluation of ankle sprain simulation showed that the mean dynamic talar tilt during simulated sprain decreased significantly in the braced ankles compared with the nonbraced ankles (dynamic talar tilt = 9.8 degrees versus 6.4 degrees braced). A significant decrease in the digital measurement of inversion distance (from 110.6 pixels to 92.4 pixels) was observed in the total sample of 39 ankles during the initial high-speed phase of the simulated sprain. The brace significantly slows down the inversion speed.

Diaphragmatic pacing in the treatment of chronic respiratory insufficiency of quadriplegic patients.

Following our experience with diaphragmatic pacing in 2 quadriplegic patients with bilateral diaphragmatic paralysis, we here present the indication for and the surgical technique of bilateral implantation of a diaphragmatic pacemaker. This mode of artificial ventilation appears to be superior to positive pressure ventilation for longterm ventilatory assistance of these patients.
