Native hip geometry restoration in total hip arthroplasty: a retrospective analysis of eight different short stems.

Purpose: To compare different types of short stems (SS) in terms of native hip geometry reproducibility, analyzing centrum-collum-diaphyseal angle (CCD) and femoral offset (FO). These parameters allow the SS to be adapted to patient's anatomy in order to ensure better functional outcomes in total hip arthroplasty (THA).

Methods: A total of 387 cases of SS met the inclusion criteria.

A different unhappy triad in the knee: a case of acute simultaneous rupture of Patellar Tendon, Anterior Cruciate Ligament and lateral meniscus treated in one stage and review of literature.

We present a case report of a 43-year-old male patient with simultaneous ruptured of anterior cruciate ligament (ACL), patellar tendon (PT) and lateral meniscus tear, occurred during a tennis match. This combinate tear is not frequent, and literature reports only few cases. Clinical diagnosis can be difficult and the support of MRI and X-Ray is needed.

Anterior Capsulolabral Reconstruction with Semitendinosus Autograft after Latarjet Failure: A Case Report.

Introduction: The treatment of chronic shoulder instability, associated with poor tissue quality, remains challenging in the setting of anterior capsular deficiency. There are a few viable alternatives in the end-stage shoulder instability when multiple surgical attempts to correct the pathology have failed. The purpose of the present paper is to demonstrate the efficacy of anterior capsular reconstruction with semitendinosus autograft for the management of capsulolabral deficiency without associated bone loss.

Bone methabolic disorders in HIV positive patients: a case report.

Fractures in patients affected by HIV are more frequent than what is reported in patients with no retroviral diseases. Chronic infection with HIV likely contributes to increased systemic inflammation, which has been associated with increased rates of fracture.  We report a case of a 56-year-old male (HIV + in treatment with Atripla) heavy worker, at the beginning affected by intra-articular proximal humerus fracture treated with endoprosthesis replacement and later by periprosthetic fracture treated with plate, screws and cerclages.
