The psoas muscle index as a useful predictor of total hip arthroplasty outcomes.
The aim of this study is to assess the association between the psoas muscle index (PMI) and total hip arthroplasty (THA) outcomes. This is a critical issue as sarcopenia has been associated with poor patient satisfaction post-THA. ⋯ The PMI, which is associated with nutritional status and global sagittal spinal deformity, does predict THA outcomes. Therefore, it can be useful when discussing THA expectations with patients.

Contralateral knee pain exacerbation after total knee arthroplasty and its impact on functional activity.
The purposes of the present study were to (1) describe the prevalence of contralateral knee pain exacerbation after total knee arthroplasty (TKA), (2) explore the risk factors for pain exacerbation, and (3) verify the association of contralateral knee pain with future functional activity. ⋯ The frequency and impact of pain exacerbation on the contralateral knee increase after TKA and should be carefully evaluated for a prolonged period of time.

Digitally enhanced hands-on surgical training (DEHST) enhances the performance during freehand nail distal interlocking.
Freehand distal interlocking of intramedullary nails remains a challenging task. Recently, a new training device for digitally enhanced hands-on surgical training (DEHST) was introduced, potentially improving surgical skills needed for distal interlocking. ⋯ II.

Valgising angular stable plate fixation in the treatment of multifragmentary proximal humeral fractures in elderly patients.
The frequency of proximal humeral fractures shows an increasing tendency, especially in the elderly, who are frequently affected by osteoporosis. The adequate treatment of complex, displaced fractures poses a serious challenge. Among surgical treatment options, osteosynthesis with an angular stable plate is preferred, however, the implant-related complication rate may be exceptionally high. In our present study, we report the short-term outcomes of our new method of valgising angular stable plate fixation which we use for multifragmentary, displaced proximal humeral fractures in elderly patients. ⋯ Valgising angular stable plate fixation that we apply for proximal humeral fractures provided favourable functional outcomes and a low postoperative complication rate due to the optimal head and plate placement. The method is especially effective for the treatment of displaced three- and four-part fractures with weakened, osteoporotic bone structure.

In vivo study to assess fat embolism resulting from the Reamer-Irrigator-Aspirator 2 system compared to a novel aspirator-based concept for intramedullary bone graft harvesting.
Fat embolism (FE) following intramedullary (IM) reaming can cause severe pulmonary complications and sudden death. Recently, a new harvesting concept was introduced in which a novel aspirator is used first for bone marrow (BM) aspiration and then for subsequent aspiration of morselized endosteal bone during sequential reaming (A + R + A). In contrast to the established Reamer-Irrigator-Aspirator (RIA) 2 system, the new A + R + A concept allows for the evacuation of fatty BM prior to reaming. In this study, we hypothesized that the risk of FE, associated coagulopathic reactions and pulmonary FE would be comparable between the RIA 2 system and the A + R + A concept. ⋯ The use of the RIA 2 system and the novel A + R + A harvesting concept which consists of BM evacuation followed by sequential IM reaming and aspiration of endosteal bone, resulted in only minor fat intravasation, coagulopathic reactions and pulmonary FE, with no significant differences between the groups. Our results, therefore, suggest that both the RIA 2 system and the new A + R + A concept are comparable technologies in terms of FE-related complications.
