Multicenter Study Clinical TrialResults of the Evora dual-mobility socket after a minimum follow-up of five years.
Dislocation is a well-known complication of total hip arthroplasty. The risk can be reduced to one or two cases per thousand using a dual-mobility cup. The survival rate achieved with the Bousquet implant is 95% at 10 years. The complications with this implant are early mobilization and inguinal pain. An overly-large cup and insufficient primary and secondary fixation can be implicated. The design of the original implant was later modified to limit these early complications. The purpose of this study was to check the validity of these design changes. ⋯ Changing the design of the implant to modify its volume, material and primary fixation has eliminated the early mobilizations and inguinal pain described for the original Bousquet cup. These options have not had any deleterious effect on prosthesis stability. The question of long-term wear remains an important problem and requires optimization: a neck as thin as possible, optimized surfacing, elimination of laser marks, extraction leads and head skirts.

ReviewTreatment of osteochondral defects of the talus.
This review article provides a current concepts overview of osteochondral defects of the talus, with special emphasis on treatment options, their indications and future developments. Osteochondral defects of the talar dome are mostly caused by a traumatic event. They may lead to deep ankle pain on weight-bearing, prolonged swelling, diminished range of motion and synovitis. ⋯ For large cystic talar lesions, retrograde drilling combined with a bone graft is an important alternative. In adolescents or in (sub)acute situations, in which the fragment is 15 mm or larger, fixation of the fragment is preferred. Osteochondral autograft transfer and autologous chondrocyte implantation (ACI), with or without a cancellous bone graft, are recommended for secondary cases as well as large lesions.

Multicenter Study[Shoulder calcifying tendinitis].
Calcifying tendinitis is a frequent shoulder disease but the surgical treatment is still debatable. The authors of this symposium reviewed retrospectively 450 patients treated by arthroscopal excision for calcifying tendinitis. Imaging were used to assess the cuff status in every case. ⋯ The arthroscopic treatment obtained good results independently from the calcification location but the surgical approach should be adapted. Functional results were lower after removing a type C calcification. Acromioplasty improved the results when the calcification was associated with an aggressive acromion or a partial cuff tear.

[Surgical treatment of anterior shoulder instability in rugby players: clinical and radiographic results with minimum five-year follow-up].
In rugby players, 9 to 11% of injuries involve shoulder trauma. Anterior dislocation is one of the most severe accidents affecting the upper limb; recurrent dislocation, observed in more than 60%, appears to be related to the characteristic mechanism of injury in this sport (tackling). Surgical treatment for this instability is a bone block or capsulolabral repair. The purpose of this work was to evaluate outcome with minimum five-years follow-up after treatment by selective capsule repair in a homogeneous series of rugby players. ⋯ Young age appears to be a major factor, predictive of recurrence after a first instability accident; the type of sport would only be indirectly involved. Nevertheless, for patients playing this type of contact sports, the appropriateness of surgical stabilization can be debated; arthroscopic anatomic methods have not yet yielded results equivalent to open surgery. The results in this series are similar to those found elsewhere in the literature, but with a follow-up longer than generally reported. Anatomic reconstruction of anterior stability elements enables these patients to resume their contact sport at an equivalent level with restored joint motion.

[Recurrent anterior instability of the shoulder associated with full thickness rotator cuff tear: results of surgical treatment].
Recurrent anterior dislocations associated with full thickness rotator cuff tear (RCT) carry a difficult therapeutic problem: should we treat instability and rotator cuff tear at the same time or only one of both pathologies? The goal of this study was to analyse a retrospective series of patients operated on to try to answer this question. ⋯ In case of recurrent dislocations associated with rotator cuff tear, treatment of instability should be proposed whereas the concomitant repair of the cuff depends upon the possibility to perform it: size of the rupture, fatty infiltration, age and motivation of the patients.
