[Anomalous implantation of the appendiceal base. A case report]. / Anomalia di impianto della base appendicolare. Descrizione di un caso.

The authors report a case of anomalous appendicular implantation observed in a 17-year-old male. The appendix was not found in its usual site, but upon the antero-lateral wall of ascending colon, 15 cm from the junction of the taenia of caecum. A partial mobilization of caecum was required for appendectomy. By a review of recent bibliography this anomaly seems very unusual considering the poor number of reports in literature. The anatomy and embryology of the vermiform appendix are briefly presented, and at the same time the possible pathogenetic hypothesis of this anomaly, such as described by other colleagues. The authors underscore how, knowledge of another case report, in their experience, suggested to search for appendix in an unusual site, before concluding for an appendicular agenesis.

Recurrent posterior subluxation of the shoulder.

The rare posterior form of instability syndrome of the shoulder is taken into consideration. A diagnostic protocol aimed at revealing posterior slipping of the humeral head following spontaneous movement or with stress is suggested; this involves semiological maneuvers, and the help of radiographs in specific projections and CT scan. As for treatment, the importance of physiatric treatment is emphasized, and surgery advised in young patients who do not benefit from conservative treatment. The authors prefer posterior capsulomyoplasty associated with posterior glenoplasty in forms of the pathology characterized by excessive glenoid retroversion. Finally, 4 personal cases are presented.
