[Is there a role for ambulatory management of emergencies?].

The Public Health Code includes the practice of ambulatory surgery. The regulations are well defined and different from the practice of out patients' care. Good practice of this surgery necessitates the will and involvement of the patient, the support of his/her family which means that the operated patient is not alone when he/she returns home after surgery and a medical team remains in contact with the patient. The majority of hand trauma surgical procedures can be performed by ambulatory surgery. Only operations necessitating permanent post-operative care and specific treatment as in the case of intense pain and surgical procedures in multi-trauma require traditional hospitalisation. To this day, there is no or very little litigation related to this surgical practice; the rules and professional obligations are the same as those for surgery with traditional hospitalisation. There are less risks of hospital infections because the operated patient spends only a few hours in the hospital. The rules specify that the proper functioning is under the responsibility of the co-ordinator of the ambulatory surgery unit.

[The Roseland prosthesis in the treatment of osteoarthritis. A five years experience with the same surgeon].

INTRODUCTION: The results of the Roseland trapeziometacarpal prosthesis in the treatment of the TMP arthritis has been reviewed and the trapezial component fixation discussed. METHOD: The material has been collected between November 1995 and January 2000. The immobilisation lasted 15 days if the prosthesis was cemented and one month if not. The following criteria were studied: pain, opposition, first and the second metacarpal angle, patient satisfaction, X-rays data, surgeon opinion on the components position, complication and re-operation. RESULTS: The series is made of 45 cases (43 patients), eight males and 37 females. The average age was 59.7 years, with an average pre-operative duration of 3.5 years. X-rays data shows 43% with Dell II and 33% with Dell III aspect. 19 prosthesis were cemented, 22 not, 9 cases had a mixed fixation. The average follow up is 14 months. There was no or few post-operative pain (74% of cases). The opposition has been improved in most of the cases. 78% of the patients were satisfied. Post-operative X-rays were correct in 66% for the trapezial component and in 86.5% with the metacarpal one. There were 12 complications, with eight trapezial component failures. Eight patients were re-operated on. All cases were satisfying then. DISCUSSION: If some foreign causes occurred in some complication, six failures were due to a technical problem. We must point out the frequency of failure with the cemented trapezium. However, the Roseland prosthesis is a satisfying arthroplasty but the trapezial component implantation must be improved.

[Epineural layer of the median nerve in carpal tunnel syndrome].

The different factors influencing a nerve compression have been studied regarding to the anterior epineurium modifications. Depending on the interstitial collagen sclerosis 3 histological groups have been separated in 55 patients. There is no influence on the epineurium layer depending on the pre-operative electrologic neuro-stenosis and denervation data. The macroscopic status of the nerve and the epineurium sclerosis have no parallelism. The age and the number of corticoid injections have no influence on the epineurial sclerosis. The only influencing factor on the histological aspect of the epineurium is the long term duration that precedes the surgery.

[Compression of the median nerve in the carpal tunnel due to an intra-canal palmar muscle].

Five cases of palmaris longus muscle in the carpal tunnel responsible for median nerve compression are reported. This represents less than 0.5% of all carpal tunnel syndromes operated over a ten year period. A review of the literature reports this abnormality in about 0.5% of tendons examined. It is important to recognise these forms for carpal tunnel and tendon transfer surgery.

[Unusual complications of median nerve neurolysis].

Two cases of acute post-operative compression of the ulnar nerve after, nerve release of the median nerve in the wrist are reported. The ulnar, nerve was free of any lesion on the preoperative clinical or electrical examination, at the elbow or the wrist. Stenosis of this nerve occurred during the month following the median nerve release as confirmed by EMG. The compression was treated by ulnar nerve release. Such a complication, representing 0.2% in a series of 982 cases of carpal tunnel syndrome, has never been mentioned in the literature. The authors suggest an etiopathogenic hypothesis which guides a new surgical approach.

[The carpal-metacarpal joint. A radio-dynamic study].

The authors report the results of 178 dynamic A-P X-rays of the wrist. Calculation of the angles between the radius and the capitate and between the radius and the third metacarpal during movements of maximal abduction and adduction of the wrist demonstrates carpo-metacarpal mobility, so that during ulnar inclination, the joint accentuates the global displacement while in radial inclination, it decreases it.

[Controlled healing in the treatment of Dupuytren's contracture by the McCash's technic].

Results of a short series of cases, without statistical pretension, have shown that controlled cicatrisation during treatment of Dupuytren's contracture by open palm method appears to be obtained somewhat more rapidly and to be of better quality using an antiseptic rather than a greasy dressing. Equally, this method has the non-negligible advantage of being less onerous and of very simple management.

Biodynamics of the wrist: radiologic approach to scapholunate instability.

A study of 126 normal wrists has allowed us to determine the normal laxity of the scapholunate complex (36 degrees) by measuring and comparing the range of movement of each of these two bones on sagittal views on x-ray films. There was no difference between dominant and nondominant hands. A study of eight cadaver wrists and 13 pathologic wrists has shown greater SL in the presence of scapholunate ligament lesions. The measurement of SL on dynamic sagittal views on x-ray films can detect a pathologic laxity between these two bones. A minimal 15 degrees difference between a normal and a pathologic wrist is reliable.

[Radiological study of the height of the cubitus in relation to the radius. Measures of 2 comparative series].

It has been postulated that cubitus altus promotes Kienböck's disease. The inconstant value of the radioulnar index must be underlined. Our index is measured on sagittal X-rays. This study showed that the angle formed between the horizontal line which passes through the junction of the lower and ulnar borders of the radius and the line drawn from this same ulnar pole of the radius to the lower ulnar styloid (Fischer's angle) on posteroanterior projections was not reliable. In an initial study of 41 men and 36 women, the following mean values were found : 1.06 for men ; 0.65 for women. The minus sign indicates that the ulna was shorter than the radius. A second study showed that there was in fact very little difference between men (-2.08 mm) and women (-1.91 mm). Based on the study of 150 normal wrists, it seems possible to state that the physiological radioulnar index ranges from 0.5 mm to 2 mm on sagittal X-rays. The ulna was always shorter thant the radius, was slightly shorter in men than in women. We suggest that values of greater than 2.5 mm are necessary to define cubitus altus.

Radiological study of the mobility of the scapho-lunate joint.

Based on the study of 126 wrists, it was possible to determine that 36 degrees of normal laxity exists in the scapholunate complex. This was documented by the comparative measurements of the total range of movement of these two bones on sagittal plane X-rays. No difference between the dominant and non dominant hands was observed. Cadaveric experimental studies as well as the records of 13 pathological wrists showed that scapholunate laxity was greater when the scapholunate ligament was involved. Measuring scapholunate movements on sagittal motion roentgenographic views can detect pathological laxity between these two bones, considering that 15 degrees is the minimal difference permitted.

[Vertical fractures of the hamate bone].

Two cases of a fracture of the hamate bone are reported. Diagnosis has been made with the help of tomography. The first case was treated by operative intervention and the second by a closed method. The authors clarify the mechanism of this rare fracture, which is caused by a direct stress, on the closed fist. They present two therapeutic possibilities.

[Hemi-epiphyseal lengthening of the ulna in Kienboeck's disease].

The authors report the first results of a hemiepiphyseal lengthening of the ulna in a case of Kienböck's disease. Only the articular portion of the inferior epiphysis of the ulna is lengthened, the position of the styloid ulna being left untouched. The results of 17 cases are analysed. There were no cases of pseudarthrosis. The risk of conflict between the styloid ulna and the triquetrum is avoided.

A double-blind trial comparing disodium cromoglycate (DSCG), and ketotifen in extrinsic asthmatic children.

A double-blind non crossover trial comparing disodium cromoglycate (DSCG), with ketotifen, was carried out in twenty-seven extrinsic asthmatic children over 12 weeks. Assessment was made using symptom score and drug score charts. Both drugs showed a similar protective effect in the group studied. None of the subjects had to withdraw from the trial and no side-effects were noted in weight-curve, arterial pressure and pulse rate. PEFR values remained unchanged for both drugs throughout the trial. A non-significant tendency for additional corticosteroid support in the Ketotifen group was noted.
