RESUMO
Purpose@#Total hip arthroplasty (THA) using dual mobility components (DMC) is a reasonable surgical option for displaced femoral neck fractures in elderly patients, resulting in lower dislocation rates and improved stability. The purpose of this study was to investigate the clinical outcomes and risk factors responsible for mortality in elderly patients who were diagnosed with a displaced femoral neck fracture and had undergone DMC-THA. @*Materials and Methods@#Out of 147 cases of THA from December 2018 to June 2020, a total of 79 cases were enrolled in this study, with the following characteristics: (1) Garden stage III or IV, (2) over 75 years of age, and (3) over 1 year of follow-up. All the patients received DMC-THA surgery using the anterolateral approach. @*Results@#The mean follow-up period was 15.0±8.43 months and a total of one dislocation case was observed. The mortality rate was 17.7% (14/79), and it was especially higher in patients with a past medical history of malignancy (odds ratio [OR]=7.18, p=0.03) or a cognitive disorder such as dementia (OR=5.48, p=0.03). Preoperative low initial hemoglobin levels (OR=0.65, p=0.04) and low UCLA (Uni-versity of California at Los Angeles) score (OR=0.47, p=0.02) were also associated with mortality. @*Conclusion@#When considering THA as a treatment approach in elderly patients with a displaced femoral neck fracture, a high mortality rate is expected in patients with low preoperative hemoglobin levels or a history of malignancy or cognitive disorders. Hence, thorough monitoring and management should be undertaken before and after surgery.
RESUMO
Purpose@#This study was performed to compare the clinical results and radiological follow-up differences between intertrochanteric fractures treated with the U-blade Gamma3 nail or the Zimmer natural nail (ZNN). @*Materials and Methods@#The medical records of 129 cases diagnosed with an intertrochanteric frac-ture (90 cases of U-blade Gamma3 nail, 39 cases of ZNN) from July 2015 to December 2018 were reviewed. Patients were assigned to a U-blade Gamma3 nail (n=39) or a ZNN (n=39) group. To reduce selective bias, groups were subjected to Propensity score matching by age, body mass index, bone mineral density, and fracture type. Patients that met the following criteria were excluded; age <65 years, non-ambulatory, high energy or pathologic fracture, and a follow-up of <6 months. Operation times, estimated blood losses, preoperative and postoperative Koval grades, Harris hip score and radiological lag screw positions in the femoral head, reduction quality, cut-out, tip-apex distance (TAD), lag screw sliding distances, and times to union were compared. @*Results@#Clinical results were similar in the two groups, but lag screw TAD was significantly greater in Ublade Gamma3 nail group (23.4 mm vs. 21.0 mm) (p=0.042). One case of cut-out occurred in the Ublade Gamma3 nail group, but no other nail-related postoperative complication was noted. @*Conclusion@#No significant difference was observed between the outcomes of U-blade Gamma3 nail or ZNN treatments of intertrochanteric fractures. We conclude that the U-blade confers no specific advan-tage.

RESUMO
This paper reports a rare case of the symptomatic third metatarsal (MT3) - lateral cuneiform (LC) in a 55-year-old male who presented with complaints of severe intermittent pain in his right foot. Plain radiographs and computed tomography scans revealed sclerosis and irregularity at this joint. The intraoperative findings demonstrated a fibrocartilaginous coalition. The pain had improved one year after removing the MT3-LC joint by en bloc and arthrodesis.
