Purpose: To compare outcomes (i.e., clinical and radiological findings, postoperative complication) in the fixation of intertrochanteric fractures with U-blade Gamma3 and Gamma3 nails. 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 cutout , (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 lagscrew 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 cutout 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.

Background: For Neer type IIB fracture of distal clavicle with coracoclavicular ligament injury, various surgical treatments have been used in literatures. However, there was no consensus on the optimal treatment. The aim of this study is to report the clinical and radiological results of open reduction and internal fixation of unstable distal clavicle fracture and suture augmentation of disrupted coracoclavicular ligament. Methods: A prospective study was performed in 23 patients with Neer type IIB distal clavicle fracture in Seoul Medical Center, Eulji Hospital, and National Medical Center. Firstly, suture anchors are inserted in the base of coracoid process and preliminary reduction was achieved by tie-off of three suture limbs around the clavicle. Then, the final fixation was completed with anatomical locking plate. Bony union and the distance between coracoclavicular ligaments were evaluated. Clinical results and complications including stiffness and secondary procedures were evaluated. Results: Bony union was achieved in all cases except one (22 of 23). At mean 14.9 months, no significant difference in the mean coracoclavicular distance was observed compared to uninjured shoulder (8.2 ± 7.9 mm versus 7.3 ± 3.4 mm, p=0.14). Pain visual analogue scale, American Shoulder and Elbow Surgeons score, Constant score, and Disabilities of the Arm, Shoulder and Hand score were 0.5, 83.4, 78.5, and 6.2, respectively. Revision surgery was performed in one case of nonunion. Four patients who complained of skin irritation underwent implant removal.

The objective of this work is to explore the learning of visually grounded speech models (VGS) from multilingual perspective. Bilingual VGS models are generally trained with an equal number of spoken captions from both languages. However, in reality, there can be an imbalance among the languages for the available spoken captions. Our key contribution in this work is to leverage the power of a high-resource language in a bilingual visually grounded speech model to improve the performance of a low-resource language. We introduce two methods to distill the knowledge of high-resource language into low-resource languages: (1) incorporating a strong pre-trained high-resource language encoder and (2) using semantically similar spoken captions. Our experiments show that combining these two approaches effectively enables the low-resource language to surpass the performances of monolingual and bilingual counterparts for cross-modal retrieval tasks.

Department of Orthopaedic Surgery, Seoul Medical Center, Seoul, Republic of KoreaStudy Design: Case study of two cases. Objectives: The aim of our study is to describe atypical patterns of tuberculous spondylitis. Summary of Literature Review: Few reports of tuberculous spondylitis have discussed atypical cases, which resulted in a poor prognosis due to the delay in early diagnosis and proper treatment. Materials and Methods:A 74-year-old female underwent an incision and drainage, and posterior decompression and fusion (PDF) due to tuberculous epidural abscess after vertebroplasty of a compression fracture at T12. A 52-year-old female underwent interbody fusion and posterior lateral fusion (PLF) because of aggravation of an abscess and neurologic symptoms following non-invasive intervention to treat atypical tuberculous spondylitis. Results: Clinical symptoms and serological tests of the patients were improved at postoperative 6 months. Conclusions: When a patient presents with focal bony or soft tissue abnormality on an image study, the possibility of non-typical tuberculous spondylitis has to be considered when infective spondylitis or a tumor is detected. Moreover, an invasive diagnosis tool such as biopsy will be needed for proper management.
