Carpometacarpal joint dislocations are uncommon hand injuries. These dislocations are usually misdiagnosed due to their non-specific clinical signs and tend to be difficult to identify in simple X-rays. We report our experience in the management of carpometacarpal bone dislocations at a specialized hand surgery center. Patients with carpometacarpal dislocations seen at the emergency department between 2013 and 2017 were included. All patients were treated with either closed reduction and percutaneous pinning (CRPP) or open reduction and internal fixation (ORIF). Postoperative functional assessment was performed at 6 and 18 months using the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Eleven patients were included, 8 (72%) were managed with CRPP and the rest required ORIF (28%). For the functional outcome, we found an average DASH score of 27.9 at the 6 months threshold and of 1.5 at the 18 months threshold. Carpometacarpal dislocations are uncommon and easy to misdiagnose; the hand surgeon should have a high clinical suspicion in patients who sustained high-energy trauma, and imaging studies should be thoroughly evaluated. Closed reduction and percutaneous pinning is a safe and effective treatment option, with long-term good functional results.

The known classifications for microtia have been cumbersome and difficult to apply in daily consultation. The lack of a progressive surgical behavior according to each degree of affection also contributes to confusion and in a lower success rate in clinical application. The authors propose a progressive surgical classification that takes into consideration the principal anatomical defect and the corresponding correction with modern techniques, having eliminated from previous classifications, those elements that are now considered deformations of the ear, capable of conservative treatment in early stages of life.

Mozart ear is a rare auricular deformity; clinically the auricle is characterized by the bulging appearance of the anterosuperior portion of the auricle due to fusion of the crura of the antihelix, an inversion in the normal form of the cavum conchae resulting in its convexity and a slit-like narrowing of the orifice of the external auditory meatus.A retrospective review of clinical and photographic records of patients attended at the ear reconstruction clinic of our hospital between June of 2010 and May 2016 was performed; out of 576 consecutive patients only 3 fulfilled the inclusion criteria, with a prevalence of 0.5%. The authors present these patients.Surgical interventions mainly focus on the correction of the convex concha; however, the procedure should be tailored to the severity of the deformity and the wishes of the patient.
