Four patients had all 3 embryologic remnants thyrothymic remnant, PLs, and ZTs. Conclusion An entirely separate thyroidal remnant at the thyrothymic area is not a rare variation. The considerably large size of a remnant may threaten the completeness of thyroidectomy and may result in recurrence if it is left behind after thyroid surgery. Selleck VcMMAE Awareness, identification, and excision of the separate remnant at the thyrothymic area and the other embryologic remnants are critical for ensuring completeness of thyroidectomy and preventing recurrences.

Materials and Methods A review of 162 patients (both male and female) treated for intertrochanteric fractures between December 2012 and December 2018 was conducted. All patients were older than 65 years of age and treated with U-blade Gamma3 (n=90) or Gamma3 (n=72) nails. Evaluations included (i) screw-head position, (ii) fracture-reduction status, (iii) time to union, (iv) cases of cut-out, (v) tip-apex distance, and (vi) lag screw sliding distance. Differences in pre- and postoperative ambulatory ability was also investigated. Results There were no significant differences in baseline demographics between the two groups. While the lag-screw sliding distance was significantly shorter in U-blade Gamma3 nail group (4.7 mm vs. 3.6 mm; P=0.025), the mean time to union was similar between the groups (P=0.053). Three and six cases of cut-out were noted in the U-blade Gamma3 and Gamma3 nail groups, respectively (P=0.18), however no other postoperative complications were noted in either group. Lastly, there was no difference between the change from pre- to postoperative activity level between the groups (P=0.753). Conclusion Of all the clinical and radiological outcomes assessed, the only significant improvement between those treated with U-Blade Gamma and Gamma3 nails was a shorter lag-screw sliding distance. These findings should benefit clinicians when deciding between the use of U-Blade Gamma or Gamma3 nails.

Materials and Methods Ten cadaveric hemi pelvis specimens were included. A standard arthroscopic ALP was created. Hips were randomized to SAP (n=5) or MAP (n=5) groups. The spinal needle was placed at the center of the anterior triangle or directly adjacent to the ALP in the SAP and MAP groups, respectively. A capsulotomy was created by inserting the knife through the SAP or MAP. The length and width of each capsulotomy was measured using digital calipers under direct visualization. The CSA and length of the capsulotomy as a percentage of total iliofemoral ligament (IFL) side-to-side width were calculated. Results There were no differences in mean cadaveric age, weight or IFL dimensions between the groups. Capsulotomy CSA was significantly larger in the SAP group compared with the MAP group (SAP 2.16±0.64 cm2 vs. MAP 0.65±0.17 cm2, P=0.008). Capsulotomy length as a percentage of total IFL width was significantly longer in the SAP group compared with the MAP group (SAP 74.2±14.1% vs. MAP 32.4±3.7%, P=0.008). Conclusion The CSA of the capsulotomy and the percentage of the total IFL width disrupted are significantly smaller when the interportal capsulotomy is performed between the ALP and MAP portals, compared to the one created between the ALP and SAP. Surgeons should be aware of this fact when performing hip arthroscopy. Copyright © 2020 by Korean Hip Society.Purpose Arthroscopy for repair of femoroacetabular impingement (FAI) and related conditions is technically challenging, but remains the preferred approach for management of these hip pathologies. The incidence of this procedure has increased steadily for the past few years, but little is known about its potential long-term effects on future interventions. The purpose of this study was to evaluate whether prior arthroscopic correction of FAI pathology impacts postoperative complication rates in patients receiving subsequent ipsilateral total hip arthroplasty (THA) on a national scale. Materials and Methods A commercially available national database - PearlDiver Patients Records Database - identified primary THA patients from 2005 to 2014. Patients who had prior arthroscopic FAI repair (post arthroscopy group) were separated from those who did not (native hip group). Prior FAI repair was examined as a risk factor for complications following THA and a multivariable logistic regression analysis was applied to identify risk factors for complications following THA. Results A total of 11,061 patients met all inclusion and exclusion criteria; 10,951 in the native hip group and 110 in the post arthroscopy group. Prior FAI repair was not significantly associated with higher rates of 90-day readmission (P=0.585), aseptic dislocation/revision within 3 years (P=0.409), surgical site infection within 3 years (P=0.796), or hip stiffness within 3 years (P=0.977) after THA. Conclusion Arthroscopic FAI repair is not an independent risk factor for complications following subsequent ipsilateral THA (level of evidence III).

However, removal of well-fixed cement is technically demanding and associated with numerous potential complications. For theses reasons, two-stage revision with preservation of the original femoral stem can be considered and several previous studies have achieved successful results. While most prior studies used cemented stems, the use of cementless stems during arthroplasty has been gradually increasing; this study aims to assess the comparative effectiveness of a two-stage revision of infected hip arthroplasties at preserving cemented and cementless stems. Materials and Methods Between December 2001 and February 2017, Inje University Sanggye Paik Hospital treated 45 cases of deep infections following hip arthroplasty with a two stage revisional arthroplasty using antibiotics-loaded cement spacers. This approach was applied in an effort to preserve the previously implanted femoral stem. Of these 45 cases, 20 were followed-up for at least two years and included in this analysis.
