Long-term results of short stem total hip arthroplasty in patients with osteonecrosis of the femoral head.
Short stem total hip arthroplasty (THA) is an alternative to conventional stem, designed to facilitate minimal-invasive surgery, physiological loading and preserve bone stock. However, there is insufficient evidence of the long-term outcomes in patients with osteonecrosis of the femoral head (ONFH). This study aims to analyze the clinical and radiographic results with a minimum follow-up of 10 years. Furthermore, the survival rate of the short stem was calculated. ⋯ Short stem showed promising long-term clinical outcomes in patients with ONFH. The radiographic results demonstrated physiological proximal load transfer.

An increased medial proximal tibial angle of greater than 95 degrees after opening wedge high tibial osteotomy is not associated with deterioration of minimum 10-year clinical outcomes.
The purpose of this study was to assess whether an excessively increased medial proximal tibial angle (MPTA) resulted in the deterioration of long-term clinical outcomes after opening wedge high tibial osteotomy (OWHTO) for patients with knee osteoarthritis (OA). ⋯ Increased MPTA > 95° after OWHTO is not associated with deterioration of minimum 10-year clinical outcomes.

Displaced dorsal rim fragment in distal radius fracture: what is the size threshold for compromise?
This study aimed to explore the effect of displaced dorsal rim fragments under defined size threshold on the clinical outcome. ⋯ For dorsal rim fragments comprising less than 10% of the radiocarpal articular surface in distal radius fracture, mild displacement does not significantly affect the recovery of wrist function.

Impact of the difference between preoperative planning and intraoperative femoral neck osteotomy level on stem alignment.
The combined anteversion theory is used for implant placement in total hip arthroplasty (THA). While majority of the research emphasizes the precise placement of the acetabular cup, there's less focus on stem alignment. This study aimed to investigate the impact of the discrepancy between the preoperatively planned femoral neck osteotomy level and the actual osteotomy level during surgery on stem alignment. ⋯ The study examined how differences in planned vs. actual femoral neck osteotomy affect stem alignment in THA using ACTIS stem and Taperloc stem. We found that osteotomy level influenced varus/valgus alignment; mildly affected flexion/extension; and had no effect on anteversion.

Mid-term outcomes of compaction autologous bone grafting in uncemented primary total hip replacement stems.
Fixation and long-term stability of collared, uncemented stems, such as the CORAIL® collared stem, in total hip arthroplasty (THA), depend on a strong cancellous bone sleeve and subsequent osseointegration. This study aimed to investigate bone reaction and mid-term outcomes following compaction autologous bone grafting in uncemented stems in primary THA. ⋯ Autologous compaction bone grafting achieved satisfactory fixation of the uncemented CORAIL® collared stem without requiring distal fixation and mitigated stress shielding. Larger, prospective studies with longer follow-ups are needed to confirm the clinical implications of these mid-term results in primary THA.
