Aims: To accurately assess subsidence, rotation and clinical scores in two cementless femoral stems.
Methods: 260 patients received either K2 or Apex femoral stems and were studied over 2y, with RSA and clinical scores.
Results: Mean Oxford Hip score for both stems was excellent (45.78 and 46.76). Very little subsidence or rotation were noted on RSA in either stem. There were no statistically significant differences in clinical scores, or radiological motion between stems. Revision rate was 0.8% over the study period.
Conclusion: Excellent clinical and RSA scores over the 2y study period predict good long term outcomes for these stems.

Objectives: To evaluate the effectiveness of mini-implant (MI) anchorage versus conventional anchorage for the treatment of skeletal class II malocclusion.
Materials And Methods: The study was conducted on 64 patients with skeletal class II malocclusion. The patients were divided into two groups: 1) 32 patients underwent conventional anchorage, and 2) 32 patients underwent MI anchorage.

Background: A fully automated artificial intelligence-based tool was developed to detect and quantify femoral component subsidence between serial radiographs. However, it did not account for measurement errors due to leg position differences, such as rotation or flexion, between comparative radiographs. If there are small differences in rotation or flexion of the leg between comparative radiographs, the impact on subsidence measurement is unclear.

Unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) is an advanced, minimally invasive spinal surgical technique characterized by the use of 2 discrete portals-one for clear visualization and continuous irrigation and the other for the dexterous manipulation of surgical instruments. This configuration not only affords an expanded view (0° or 30°) but also enhances the freedom of movement for instruments, thereby augmenting the precision and flexibility of the surgery. The superiority of UBE-TLIF lies in its capacity to facilitate rapid postoperative recovery with minimal trauma, reduced intraoperative bleeding, abbreviated hospital stays, and significant amelioration of postoperative lower back pain.

Background: The straight and thin design of the CLS Spotorno stem makes it prone for coronal plane mal-alignment, with potential for cortical impingement; reactive osteogenesis and thigh pain have been documented in this situation with some stems. The literature is scarce about the effect of distal mal-alignment with this particular stem, and its relationship with thigh pain, functional outcomes and stem survival. We assessed functional outcomes with incidence of varus/valgus CLS stem alignment, and correlated stem subsidence of these thin stems with hip scores.
