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.
