The purpose of our study is report outcomes and after adopting new in Chinese patient population.From 2016 2018, single surgeon's first 100 cases with unilateral DAA THA were reviewed. patients divided into 2 groups, 50 designated as group A second B. preoperative, intraoperative, postoperative clinical data analyzed. cumulative...

This study aimed to explore whether intraoperative nerve monitoring can identify risk factors and reduce the incidence of injury in patients with high-riding developmental dysplasia.We conducted a historical controlled unilateral Crowe IV dysplasia hip (DDH). Between October 2016 2017, femoral sciatic nerves was applied total arthroplasty (THA). A neuromonitoring technician employed monitor function inform surgeon ongoing changes timely manner. Patients who did not have between September...

Abstract Background The purpose of this study was to examine whether surgeon handedness could affect cup positioning in manual total hip arthroplasty (THA), and robot diminish or eliminate the impact on robot-assisted THA. Methods Fifty-three patients who underwent bilateral THA sixty-two between August 2018 July 2019 our institute were respectively analyzed study. When difference anteversion inclination greater than 5°, patient regarded as having different Their demographics, orientation...

Advocates of robot-assisted technique argue that robots could improve leg length restoration in total hip replacement. However, there were few studies to compare the posterior approach (RPA) with conventional (PA) THA and direct anterior (DAA) LLD. This study aimed determine whether techniques significantly reduce LLD compared manual DAA PA.We retrospectively reviewed cohort consecutive ONFH patients who underwent posterior, from January 2018 December 2020 one institution. One experienced...

Abstract Background We aimed to present our experience of adopting tissue adhesive as adjunct standard wound closure in total hip arthroplasty (THA) and evaluate its performance. Methods From September 2019 November 2019, we prospectively enrolled consecutive patients who underwent simultaneous bilateral THA this randomized controlled study. Standard was applied on one side while additional the other at random. collected analyzed patients’ information, including age, gender, body mass index...

Conversion of arthrodesed hips to total hip arthroplasty (THA) remains technically demanding. This study aims evaluate the safety and efficacy robot-assisted THA in hips.We retrospectively analyzed 45 ankylosing spondylitis patients with arthrodesis Chinese PLA General Hospital between August 2018 2019. All surgeries were carried out by one single surgeon. The followed at 3 months after surgery. Gender, body mass index, angle arthrodesis, operating time, intraoperative fluoroscopic times,...

Background Robotic‐assisted technology may be useful in hip revision cases with acetabular defects. However, data on the use of robotic‐assisted for such complex diseases is lacking. Case Presentation This case study described adoption MAKO treatment total arthroplasty (THA) combined severe defect (Paprosky type IIIB). accurately achieved preoperative planning; component and augment were placed original position angle as planned. reaming was successful a single pass, preserving remaining...

Ribosome production factor 2 homolog (RPF2) plays an important role in the life processes of ribosomal biogenesis; however, function and mechanism RPF2 tumors are unclear. The present study demonstrated that expression is involved chemoresistance colorectal cancer (CRC) cells. current upregulation CRC promoted resistance to chemotherapeutic agents cells, whereas knockdown leads increased sensitivity chemotherapy. In addition, it was found overexpression led increase ATP‑binding cassette...

In past studies, non-medical factors in the social-healthcare-patient triad associated with prevalence of COVID-19 have led to delays presentation patients acute appendicitis and an increase complications. However, as research progresses, there is increasing evidence a clinical association between development appendicitis.

Background: Joint hypermobility may be associated with developmental dysplasia of the hip (DDH), but no definite conclusion has been reached. On basis long-term clinical observations, we hypothesized that joint was occurrence, imaging findings, and symptoms DDH. Methods: We conducted a case-control study included 175 Chinese Han patients between 13 45 years age Hartofilakidis type-A dysplasia. All these underwent periacetabular osteotomy (PAO) November 2021 February 2023. An additional 76...

Abstract Background The impact of handedness on clinical outcomes was easily overlooked in hip replacement. This study aimed to find whether the component positioning and function were affected by total arthroplasty (THA) through direct anterior approach (DAA). Methods Total 102 patients who underwent bilateral DAA-THAs simultaneously between May 2016 November 2018 our institute reviewed. All surgeries operated one right-handed surgeon. Their demographic, cup positioning, stem alignment,...

Abstract Background The variation of femoral anteversion is not completely consistent with the grade developmental dysplasia hip (DDH), which poses challenges to replacement non-modular tapered stem. Currently, whether modular stem should be used in Crowe I and II DDH still controversial. aim this study compare clinical efficacy patients. Methods We retrospective analyzed data 196 patients unilateral from January 2015 2017. One hundred were operated by an experienced surgeon stems; remaining...

Surgeon handedness has been widely discussed in operative surgery, and could cause clinical discrepancy. However, few studies have reported the effect of on unicompartmental knee arthroplasty (UKA). Based our observation case analysis, we aimed to find out effects surgeon UKA.We retrospectively studied 94 UKA procedures performed by one right-handed from January 2017 December 2018 at a single medical center. The cases were divided into two groups operation side (49 L-UKAs 45 R-UKAs)....

Background: The study focusing on the tissue adhesive in total knee arthroplasty (TKA) was rare. This aimed to evaluate clinical outcomes and economic costs of when acting as adjunct standard incision closure TKA. Patients Methods: From September 2019 November 2019, we prospectively enrolled consecutive patients who underwent simultaneous bilateral TKA our institute. allocation using done after subcuticular suture right first another method applied left automatically. patients' demographics,...
