Is the natural course of perioperative laboratory testing effective in identifying wound-related complications following primary total hip arthroplasty?

Introduction: Previous study did not clarify the correlation between the natural course of perioperative blood tests and occurrence of wound-related complications, including SSI, PJI, and delayed wound healing. This study aimed to investigate whether perioperative laboratory test is effective in identifying wound-related complications after THA.

Materials And Methods: This retrospective, single-institutional study enrolled 1072 patients who underwent primary THAs.

Do elevated preoperative serum inflammatory markers influence surgical site or periprosthetic joint infections following primary total hip arthroplasty?

Background: We aimed to determine whether elevated preoperative serum inflammatory markers influence surgical site infections (SSIs) and periprosthetic joint infections (PJIs) after primary total hip arthroplasty (THA).

Methods: In this retrospective single-institution study, 1115 patients who underwent primary THA were enrolled. Cases of SSI/PJI were identified.

Relationship between Respiratory Function and the Strength of the Abdominal Trunk Muscles Including the Diaphragm in Middle-Aged and Older Adult Patients.

Respiration plays an important function in sustaining life. The diaphragm is the primary muscle involved in respiration, and plays an important role in trunk stabilization. Although it has been reported that respiratory function is important for trunk muscle stability, the correlation between respiratory function and abdominal trunk muscle strength remains undetermined.

Artificial Intelligence-Based Surgery Support Model Using Intraoperative Radiographs for Assessing the Acetabular Component Angle.

Background: This study aimed to develop an artificial intelligence-based surgical support model for assessing the acetabular component angle using intraoperative radiographs during total hip arthroplasty and verify its accuracy.

Methods: A total of 268 hips were analyzed. At first, 268 preoperative and intraoperative anteroposterior pelvic radiographs were amplified to 536.

Life Course Epidemiology of Hip Osteoarthritis in Japan: A Multicenter, Cross-Sectional Study.

Background: The incidence of developmental dysplasia of the hip (DDH) in Japanese newborns has reduced drastically following a primary prevention campaign initiated around 1972 to 1973; this perinatal education campaign promoted maintaining the hips of newborns in the naturally flexed-leg position. The purpose of the present study was to describe the life course epidemiology of hip osteoarthritis (OA) in adolescent and adult patients and to assess its association with exposure to the primary prevention campaign for DDH.

Methods: We included new patients with hip OA diagnosed from January 1, 2022, to December 31, 2022, at 12 core hospitals (8 special-function hospitals and 4 regional medical care support hospitals).
