[Inguinal hernia under laparoscopy. Pubic osteitis].

Osteitis pubis is a well known complication of urologic procedures but its association with herniorraphy is poorly documented in the literature. We report a case of osteitis pubis after coelioscopic cure of hernia. It is too early to know its frequency in coelioscopic repair. The choice of this technic might be discussed if it appears that with this technic the frequency is higher than in traditional surgery where it was rare.

Stenosis of the lumbar spinal canal in vertebral ankylosing hyperostosis.

Certain morphologic features frequently observed in radiography or computed tomography (CT) scan in patients with hyperostosis led us to study the association between a narrowed spinal canal and vertebral hyperostosis. Twenty-eight items were selected and studied by three different investigators (two rheumatologists and one radiologist) in radiographs and CT scans of 100 patients with acquired stenosis of the lumbar canal, with or without hyperostosis (46 and 54 cases, respectively). The most distinctive points that we suggest can be used as diagnostic criteria of the hyperostotic narrowed lumbar canal are anterior or posterior lateral marginal somatic osseous proliferations, proliferations of the nonarticular aspects of the posterior apophyses, and ossifications of the posterior articular capsule and of the ligaments (yellow ligament, posterior longitudinal ligament, and the supraspinal ligament). Four of these six criteria should be present to establish the diagnosis of hyperostotic lumbar stenosis. The appearance of lumbar hyperostosis on X-ray or CT scans differs from that of simple degenerative changes due to arthrosis, and the hyperostosis can be held responsible for dural compression.

[Association of lumbar canal stenosis and ankylosing vertebral hyperostosis. Results of a multicenter study].

The authors report data collected in a study of the association of narrow lumbar canal and vertebral hyperostosis. Five centres (Montpellier, Toulouse, Lille, Lyons and Paris) participated in this cooperative study which was both retrospective and prospective. Grid case forms were sent to homogenise the date provided. Two hundred and sixty nine cases of symptomatic lumbar canal stenosis were collected; 89 (33 per cent) had hyperostosis. Hyperostosis was definite in 74 cases and probable in 15 other cases. Certain radiological and/or CT scan morphological factors seen frequently in the hyperostosis patients group led us to undertake a second study in 2 of the 5 centres (Montpellier and Toulouse) in order to identify their specificity. Twenty eight items were adopted and studied by 3 different evaluators (2 rheumatologists and one radiologist) in the X-ray films and CT scan documents of 100 patients with acquired lumbar canal stenosis with or without hyperostosis (46 and 54 cases respectively). The most discriminative appearances, which we suggest as diagnostic criteria of narrow lumbar canal with hyperostosis concern anterior and/or posterolateral marginal somatic bone proliferations on the non-articular surfaces of the posterior apophyses and ossifications of the posterior joint capsule and of the ligaments (ligamentum flavum--posterior longitudinal ligament--supraspinous ligament). Four of these 6 criteria are necessary to make the diagnosis of lumbar stenosis with hyperostosis. The radiological and CT scan appearances of lumbar hyperostosis appear to differ from ordinary degenerative changes of osteoarthrosis and hyperostosis may be held responsible for compression of the dural cul-de-sac.

[The Temporomandibular Joint Diseases Unit of the Villeneuve-Saint-Georges Hospital Center].

A disease as complex as that of temporomandibular joint dysfunction can only be managed by a multidisciplinary team. The authors describe the temporomandibular joint diseases unit of the Centre Hospitalier de Villeneuve-Saint-Georges which consists of Stomatologists, Radiologists, Psychiatrists and Psychologists and a Rehabilitation Medicine doctor specialised in electrodiagnosis. The hospital's Department of Stomatology and Maxillofacial Surgery (Doctor Pierre Scheffer) coordinates this unit which holds committee meetings one a month to evaluate each case. The therapeutic decisions reflect the multiplicity of the aetiologies, none of which are mutually exclusive, which explains the necessity for a multidisciplinary approach.
