We compared the outcomes of the mini-posterior and 2-incision total hip arthroplasty approaches by analyzing 43 matched pairs of patients. The following outcomes were evaluated: (1) Harris Hip Score, (2) Medical Outcomes Study 36-Item Short-Form Health Survey, (3) the Medical Outcomes Study Sleep Scale, and (4) the Western Ontario and McMaster Osteoarthritis Index. Function was regained earlier by patients having the 2-incision total hip arthroplasty as determined by length of hospitalization (P = .002) and multiple return to function parameters, although this may be the result of hip precautions placed on the posterior group. Posterior mini-incision patients had less operating time (P < .0001) and blood loss (P = .001). Complications did not differ between surgical techniques. No patients were revised. The 2-incision operation was better for function and length of stay, and the posterior mini-incision was easier to perform, although these groups used different selection criteria.

Introduction: Optimizing treatment strategies in polytrauma patients is a key focus in trauma research and timing of major fracture care remains one of the most actively discussed topics. Besides physiologic factors, associated injuries, and injury patterns also require consideration. For instance, the exact impact and relevance of traumatic brain injury on the timing of fracture care have not yet been fully investigated.

Background: Several studies reported an association between the number of teeth and the incidence of hip fractures in observational studies, mainly in middle-aged adults. This retrospective cohort study aimed to clarify the association between the number of teeth and the incidence of hip fractures.
Methods: In this retrospective cohort study, a total of 256,772 participants aged 75 years or older who underwent public dental checkups in Japan were evaluated.
Introduction: Zinc, an essential trace element, plays an important role in various cellular processes, and zinc deficiency is common in patients undergoing hemodialysis. Zinc has been shown to stimulate osteoblastic bone formation and mineralization and inhibit osteoclastic bone resorption. Although osteoporosis is highly prevalent among patients undergoing hemodialysis, the utility of areal bone mineral density (aBMD) measured using dual-energy X-ray absorptiometry (DXA) is limited because DXA cannot reveal bone microarchitectural alterations.

In hip arthroplasty, relative movements between the femoral stem and bone can lead to implant loosening, resulting in extensive bone loss. Acoustic emission (AE) analysis is a promising technique for a nondestructive and noninvasive detection of these relative movements. To develop such a detection method, in vitro investigations using piezoelectric AE sensors on implant stems in artificial or human femora are required to characterize the AE signals induced by loosening.

Background: Precise and accurate glenoid preparation is important for the success of shoulder arthroplasty. Despite advancements in preoperative planning software and enabling technologies, most surgeons execute the procedure manually. Patient-specific instrumentation (PSI) facilitates accurate glenoid guide pin placement for cannulated reaming; however, few commercially available systems offer depth of reaming control.
