[Ganglion cyst of the shoulder: six cases and review of the literature].

Paraglenoid glenohumeral cysts can be observed in 2-4% of the general population, particularly in men during the third and fourth decade. On average, these cysts measure 10-20 mm in diameter and are located preferentially on the posterosuperior aspect of the glenoid. An articular origin (rim injury) is generally accepted. The pathogenesis is similar to that of meniscal cysts. Depending on the exact localization, there is generally little clinical expression. The most frequent complication involves compression of the suprascapular nerve leading to suffering of the supra and/or infraspinatus. Amyotrophy can occur without clinical expression. An attentive examination is necessary to identify the cyst. EMG is often falsely negative. MRI is currently gold standard diagnostic tool but will probably be improved with arthro-MRI. Ultrasonography and computed tomography can visualize with difficulty small cysts located very close to the bone. The best treatment is arthroscopy which enables complete cure (emptying the cyst and resection or suture of the rim). We present a review of the pertinent literature together with a retrospective series of six cases of paraglenoid glenohumeral ganglion cysts.

[Single-portal endoscopic treatment of carpal tunnel syndrome. Results of a preliminary series].

UNLABELLED: The aim of this study was to describe the single-portal endoscopic technique developed by J. Menon for the treatment of carpal tunnel syndrome and to evaluate its results in our first 82 patients. PATIENTS AND METHODS: The technique involved insertion of a split cannula into the previously dilated carpal tunnel, followed by section of the transverse carpal ligament from its proximal to its distal edge under visual guidance via a standard arthroscope. No immobilization was used postoperatively. A homogeneous population composed of 82 consecutive patients (71 female and 11 male) with a mean age of 51 years was studied. Mean follow-up was 15 months. A questionnaire was used to evaluate results at last follow-up, and patients were categorized into four groups based on Kelly's criteria. RESULTS: Fifty one patients (62 per cent) reported complete relief of symptoms and 29 (35 per cent) a substantial improvement, for a total of 97 per cent good and very good results. The symptoms remained unchanged in two patients, of whom one underwent revision. One patient was reoperated because of symptoms due to section of the thenar branch. The arthroscopic procedure was converted to an open procedure in 3.6 per cent of cases. DISCUSSION: The main advantage of the arthroscopic method is a faster recovery. The method developed by Menon and the material it requires are simple. Complications may be less common than with the two portal method. CONCLUSION: The single portal endoscopic technique developed by Menon for the treatment of carpal tunnel syndrome is effective and safe when it is performed in carefully selected patients using a faultless technique.

[MRI in the pre-operative evaluation of lesions of the rotator cuff].

The authors report a series of 38 patients who had been examined by MRI and then operated for a rotator cuff syndrome. The correlation between the description of the cuff lesions after MRI and the surgical observations were excellent for 37 patients. In one case MRI showed a false image of tear of the supra spinatus m. on its anterior edge. This was due to a bad knowledge of the anatomy of the muscle and tendon and to a poor orientation of the frontal cut plane. This study was complete with MRI and anatomic study of 12 non embalmed cadaveric shoulders. The results showed that MRI was very sensitive (0.93) and specific (0.94) for the diagnosis of rotator cuff tears. MRI allowed also to show partial tears of the tendons of the rotator cuff. The authors propose a MRI classification of cuff lesions which permits to establish a good surgical planning.

[Lateral lumbar disk hernia].

Lateral lumbar disc herniations (L.D.H.) develop in the foramen, and compress the nerve root against the overlying vertebral pedicle. In our study of L.D.H. from the clinical, radiographical, and therapeutical aspects, we reviewed 23 cases selected from the 590 patients treated for discal herniation from 1984 to 1987. The frequency of L.D.H. in this series was 3.8 per cent. The clinical pattern brings out some suggestive signs of L.D.H. (frequency of cruralgia, a seldom very positive Lasegue's test, the paucity of spinal signs, non impulsive pain). Saccoradiculography and discography rarely evidenced the L.D.H.. The T.D.M. was the investigation of choice on condition that it was correctly used. When the image was doubtful, disco-CT confirmation should be proceeded too. This latter method of investigation enabled the possibility of sequestration to be explored. 14 patients were treated by chemonucleolysis, with 9 successful outcomes. The 5 failures were cases where chemonucleolysis should not have been indicated, mainly due to associated osseous stenosis. 9 patients underwent immediate surgery with good results in each case.
