Posterior shoulder instability managed by arthroscopic acromial pediculated bone-block. Technique.

Unlabelled: In posterior shoulder instability (recurrent dislocation, involuntary posterior subluxation or voluntary subluxation that has become involuntary), surgery may be considered in case of failure of functional treatment if there are no psychological contraindications. Acromial bone-block with pediculated deltoid flap, as described by Kouvalchouk, is an alternative to iliac bone-block, enabling triple shoulder locking by the blocking effect, the retention hammock provided by the deltoid flap and posterior capsule repair. Arthroscopy allows shoulder joint exploration and diagnosis of associated lesions, with opening and conservation of the posterior capsule; it greatly facilitates bone-block positioning and capsule reinsertion.

[The accessory soleus muscle: a report of 21 cases and a review of the literature].

Purpose Of The Study: Well known to anatomy specialists, the accessory soleus muscle was first demonstrated to be involved in painful syndromes in 1965 (Dunn). This supranumerary muscle situated in front of the calcaneum can be taken for a soft tissue tumor. The purpose of this work was to report a series of 21 patients with an accessory soleus muscle and to present the characteristic features, diagnostic methods, and treatment indications and modalities.

[Anterior snapping of the hip associated with the ilial psoas].

Unlabelled: Anterior snapping of the hip was first described in 1951 by Nunziata and Blumenfeld. The aim of this study, based upon a personal series and backed up by literature reports, is a current review of this common clinical condition, usually asymptomatic, but sometimes painful especially in athletes.

Material And Method: 12 cases in 11 patients were treated surgically: 4 men and 7 women, mean age 25 years, 7 of them regularly involved in sport.

[Retrosternal luxation of the clavicle. Apropos of 4 cases surgically treated using a temporary screwed anterior plate and review of the literature].

The authors report 4 new cases of retrosternal dislocation of the clavicle operated by capsular and ligament restoration, and temporary stabilization by anterior plating. The 4 patients were men with a mean age of 17.5 years.

[Pyramidal syndrome. Apropos of 4 cases treated by surgery and review of the literature].

Purpose Of The Study: The authors report 4 observations of Piriformis syndrome, defined as a truncked sciatalgy with sciatic nerve and branches located compression at the buttock passing through the subpiriformis canal.

Material: 4 sportive patients, 26 to 41 years old have been treated surgically after an average of one year and a half of evolution and failure of conservative treatments. The surgical procedure consisted in section of the piriformis muscle and neurolysis of the sciatic nerve.

[Chronic stress-related compartment syndrome of the forearm].

The chronic anterior compartment syndrome of the forearm is a rare pathology (3 cases have been already published), and of new knowledge. Three new cases on 2 patients (one on both sides) are described here. The authors describe recent advances about physiopathology, exploration and surgical treatment.

[Treatment of posterior instability of the shoulder joint using an acromial stop with a pediculated deltoid flap].

Our purpose has been to describe an original surgical technique without describing all the problems concerning the posterior instability. The original technique has a double effect: active with the muscular flap and passively mechanic, if necessary, by the bone graft. Five patients have been treated with this technique with a follow-up of one year and a half.

[Muscular conflict in the peroneal retinaculum caused by supernumerary muscular fascicles of the peroneus brevis. Apropos of 2 cases].

The authors describe two cases of muscular conflict in the peroneus retinaculum due to supernumerary muscular fascicules initiating a dislocation of the peroneal tendons. Removing the extra muscular portion brought about complete recovery in both cases.

[Osteochondral lesions of the dome of the talus with partial necrosis. Surgical treatment by curettage and filling].

There are several types of lesions of the talus, including non united fractures and true osteochondritis in adolescents. This article focuses on lesions of the dome of the talus having a large subchondral necrotic zone. The etiology of these lesions is unclear.

[Irradiation of bone homografts. Their use following tumor resection. Apropos of 4 cases].

Since 1978 gamma irradiation has been used for sterilization of bone allografts. The radiation source used was Co 60 (2.5 to 3 megarads).
