    ABSTRACT: The syndrome of the pedal dorsal cutaneous nerve (described by one of us in 1979) is caused by irritation of the nerve in its course at the dorsum pedis. This is a rather frequent syndrome, often overlooked. It is manifested by a distinct association of atypical pain at the dorsum pedis and in the foot. After a review of 10 cases and a literature survey, the authors describe the characteristic signs of this syndrome. There are many factors at the origin of this pathology: static deformities (pes cavus anterior, valgus calcaneus, hallux valgus), local trauma or repeated microtrauma (ill sitting shoe). The diagnosis is essentially clinical, based on a positive Tinel sign along the course of the nerve and on the result of a trial infiltration of the region. The treatment is initially conservative with correction of deformities, adaptation of shoes, and local infiltration with corticosteroids. The neurolysis (performed in 4 cases because of persistent pain), showed dystrophic fibrosis. Such histologic lesions are an argument for considering entrapment as a potential cause of the syndrome.

    ABSTRACT: In 10 cases, the authors describe the musculo-cutaneous nerve syndrome in the foot. It involves pain and paresthesias located on the dorsal aspect of the foot, occurring after local trauma or repeated microtraumas (ill fitted shoes), promoted by a static disorder (anterior hollow foot, calcaneal valgus). The diagnosis is essentially clinical, based on the presence of a Tinel sign on the dorsum of the foot and on the infiltration test. The treatment consists in the combination of local measures and steroid infiltration. Neurolysis is only indicated in case of failure of the medical treatment (4 cases). Then, it always proves to be effective.

    ABSTRACT: The Foot, organ of the erect position and of walking is a unique example of architectural wonder, of which the slightest abnormality, static as well as dynamic may be the cause of a major dysfunction. Biomechanically, it may be summarized in two triangles: a posterior triangle, static, ensuring the erect position, and an anterior triangle, dynamic or propulsive represented by the phalangeal triangle. These two triangles are connected by a metatarso-phalangeal hinge, the harmonious curvature of which ensures the orientation and the adaptation of the foot in all directions regardless of the condition of the ground.

    ABSTRACT: Two cases of calcaneum "stress" fractures are reported. The fracture, which was unilateral in the first case and bilateral in the second, occurred 15 and 18 months respectively after the initiation of fluoride treatment for osteoporosis. The simultaneous discovery of thyrotoxicosis in the second patient suggests that the role of hyperthyroidism in the occurrence of these fractures be discussed in addition to that of fluoride treatment.

    ABSTRACT: The metatarsal intercapital space is located in the forefoot, between two metatarsal heads and above the transverse inter-metatarsal ligament. The 2nd space is the narrowest, the 1st is the widest and the 3rd is the most mobile. It contains a connective tissue bursa which facilitates the sliding of the metatarsal heads. The existence of this bursa was confirmed in two cases of rheumatoid arthritis (at operation). As the bursa hypertrophies, it gradually extends beyond its normal site towards the dorsal or plantar region of the foot. The metatarsal intercapital space, like the metatarso-phalangeal joint, warrants thorough clinical investigation.

    ABSTRACT: Based on 20 years experience, and a personal series of 272 cases of reflex dystrophy (84 cases involving upper limbs, 188 cases involving lower limbs) admitted under a rheumatology unit equipped with all the available techniques of rehabilitative medicine, the authors stress the value of well conducted functional rehabilitation which, even alone, can obtain excellent results in the treatment of this disease, whatever the stage. The authors detail the modalities of this treatment. A local intra-articular or intra-canal injection of corticosteroids permits pain-free physiotherapy. The mobilisation of the lower limb is an urgent priority. Non-aggressive physiotherapeutic techniques should be adapted to the stage and the site of reflex dystrophy. Hydrokinesitherapy and the adaptation of craft techniques to occupational therapy also play an important part.

    ABSTRACT: Deformations of the foot are a logical and predictable function of the biomechanics of the foot and the constraints undergone by the articulations of the foot, that are unstabilized by the inflammatory process. They result from the combination of three factors : anevolutive teno-articular synovitis, predictible forces (the weight of the extrinsic muscle, the anti-physiological foot), and the congenital morphotype of the foot. Typical deformations (peroneal " coup de vent " of the toes, triangular metatarsus), differ on the clinical level in keeping with the morphotype but respond to the same mechanism. The " coup de vent peronier " remains the most characteristic deformation and is furthered by the excentric action of the extrinsic muscles, and in particular the foot muscle. The common denomination of deformations of the back part of the foot is represented by the valgus calcanean, linked to the action of the weight on the orsion forces that is more or less modified. A better knowledge of the cause of these deformations would make it possible to avoid, if not their apparition, at least their worsening.

    ABSTRACT: Meralgia paresthetica although it does not produce intensive pain is a cause of chronic disability, usually barely improved by medical treatment. From the report of two cases of neurolysis the authors stress on the possibility of entrapment neuropathy of the lateral femoral cutaneous nerve in its way through the femoral canal, between the inguinal ligament and the fascia-iliaca. Anatomically, there is in this canal a normal right angle between the horizontal portion (abdominopelvic) and the vertical course in the thigh. The compression is due to a thickening of the fascia-iliaca as it forms the postero inferior wall of this canal; the nerve is squeezed between the fascia and the inguinal ligament. In 60% of cases of meralgia paresthetica where this mechanism is involved, the funicular neurolysis appears to be a radical treatment.

    ABSTRACT: The rheumatoid foot may obtain relief from practical local measures that prevent the excessive use of drug therapy. These include the decrease in inflammatory phenomena thanks to local injections of corticoids (eventually synoviorthesis), the prevention of deformations through the use of various apparatuses, the protection of the skin of the palms and the nails that are fragile and rapidly altered by local hygiene care. The maintaining of sufficient support and normal walking through the use of plantar prostheses or custommade toe prostheses and by wearing shoes of excellent quality, the maintainance and preservation of articular flexibility and muscular trophicity by adapted kinestherapy and ergo therapy. Major deformations that, while they cannot be modified do not require surgery, can be alleviated with "custom-made shoes" which are at the same time light, adapted and good looking. Whatever the treatment used, local measures are the most effective at any given time.

    ABSTRACT: Xeroradiography is a new and simple radiodiagnostic technique that makes it possible to analyse on one positive film not only the bone tissue but also the neighbouring structures (ligaments, muscles, fatty tissue, the vessels, and the skin). On the basis of about 100 examinations, the authors indicate the value and the limitations of the technique in rheumatological practice. Because of the technical aspects of the technique, the dorsolumbar spine and the facial massif are poorly visualized. The swamping of the contrast also limits its use for cases of demineralization (osteoporosis). On the other hand, the information provided by the technique in cases of Paget's disease, articular or para-articular calcification, pathological conditions of the tendons (rupture, calcification), and bone tumours appears to be of great value. The early diagnosis of cases of inflammatory rheumatism and the surveillance of Silastic prostheses used in surgery on rheumatic hands are also facilitated.

    ABSTRACT: Paget's disease of the bones of the feet is not unusual. Twenty patients out of every hundred present the signs of Paget's disease in the foot bones. The calcaneus is the bone most often affected (18 cases) but the cuboid, the metatarsals, and the astragalus (often as well as the calcaneus) may also be affected. Paget's disease of the foot remains latent clinically: 2 patients complained of talalgia; a third had a deformation of the rear part of the foot which made it difficult to wear a shoe. Pagetic deformations of the lower limb affect the foot but without pain. They are often compensated for by putting more weight on the fore-foot in cases of shortening of the lower limb or on the external arch in cases of bowed deformation of the lower limb.

    ABSTRACT: The etiology of Paget's disease is just as doubtful in 1975 as it was in 1876 when Sir James Paget described the disease. The authors analyse the etiology on the basis of 100 personal cases and the literature. Although there are undoubtedly familial cases of the disease, investigation of the leucocyte grouping of 46 patients with Paget's disease did not reveal any correlation between occurrence of the disease and the HL-A antigens. Various pathological associations have been reported in the literature and were also found in this series. These associations were at the limits of coincidence (inflammatory rheumatism, diffuse chondrocalcinosis, multiple myeloma...). Metabolic changes (hyperuricaemia, hyperglycaemia, dyslipidaemia) did not appear to be more frequent than in control patients. Involvement of elastic tissue and the presence of pseudocrystalline inclusions in the osteoclasts constitute interesting points for discussion.
