Introduction: Calcaneal fractures (CF) are the most common tarsal fractures, representing up to 75% of foot fractures and 2% of all fractures. The aim of this retrospective study is to analyze fixation with Kirschner wires through a mini-invasive approach and dedicated plate and screws through an extended approach at long-term follow-up. Materials and Methods: Patients were radiographically and clinically evaluated at final follow-up, by using the validated American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score for the clinical–functional assessment, the Short-Form 12 (SF-12) for the physical and psychological domain assessment, and the Visual Analog Scale (VAS) for pain. Results: In total, 38 patients (42 CF) met the inclusion criteria and were retrospectively evaluated and divided into two groups (Kirschner group and plate group) consisting of 19 patients each. The overall mean follow-up was 59.4 ± 11.8 months. The average values of the post-operative clinical outcomes of the two groups KG and PG were, respectively, 70.7 ± 11.9 and 70.1 ± 10.9 (AOFAS), 45.7 ± 6.8 and 46.5 ± 10.8 (SF-12 PCS), 54.7 ± 9.9 and 50.9 ± 11.8 (SF-12 MCS) at the final follow-up. Conclusions: The present study showed that in the cases analyzed, the two surgical approaches used for the treatment of CF achieved comparable clinical outcomes. The only substantial difference found between the two groups of patients was the re-intervention rate that afflicted them.

Osteoarthritis (OA) of the ankle affects about 1% of the world’s adult population, causing an important impact on patient lives and health systems. Most patients with ankle OA can show an asymmetrical wear pattern with a predominant degeneration of the medial or the lateral portion of the joint. To avoid more invasive ankle joint sacrificing procedures, joint realignment surgery has been developed to restore the anatomy of the joints with asymmetric early OA and to improve the joint biomechanics and symptoms of the patients. This narrative, comprehensive, all-embracing review of the literature has the aim to describe the current concepts of joint preserving and reconstructive surgery in the treatment of the valgus and varus ankle early OA, through an original iconography and clear indications and technical notes.

Objective. Instability is considered a leading cause of early revision in total hip arthroplasty. Dual mobility cup (DMC) has shown to be a good solution for this problem. However, using DMC there is the potential complication of malseating of the liner. The study aims to determine the incidence of DMC malseating in a large volume hospital where different modular constructs are used, and if there is a significant difference in the incidence between the different constructs used. Methods. In this retrospective study, we included patients admitted at single institution from January 2016 to March 2020. One-hundred-and-one patients were enrolled. Fifty-seven patients were male, the mean age was 61 years, and the mean body mass index was 25.9 kg/m2. Results. Three patients had radiographic evidence of liner malseating. In one patient, the radiological divergence disappeared at one-year follow-up. One patient showed an unfavorable evolution with a progressive increase of the divergence of the shell line associated with a painful noise. He eventually underwent revision surgery. Conclusions. In high-risk patients, DMC component provided a low risk of dislocation and good overall survival.
