Stem subsidence in total hip arthroplasty: retrospective investigation of a short stem using a simple measurement approach.
Uncemented total hip arthroplasty (THA) is a successful treatment for advanced hip joint diseases. More recently, short stems became increasingly popular, but stem subsidence remains a concern. This study investigates early short stem subsidence in a large patient cohort using a simple measurement approach for everyday practice. ⋯ Early subsidence is relatively frequent with this uncemented short stem, however revisions are rare. Patients with risk factors should be counseled regarding FWB and radiographic controls should be performed. The SID provides an easy, non-invasive and inexpensive tool for early subsidence assessment; however, its simplicity limits its accuracy. Further research is needed in comparison to more elaborate methods.

The scaphoid bone is essential for wrist stability, force transmission, and movement, being crucial for maintaining carpal kinematics. In cases where the scaphoid is non-reconstructable, a complete replacement can serve as a treatment option to preserve carpal alignment and motion. This approach has evolved since its first descriptions in 1945, benefiting significantly from advancements in patient-specific implant design, additive manufacturing/3D printing, and material use in recent years. We present a technique for scaphoid replacement using a patient-specific prosthesis and reconstruction of intrinsic and extrinsic ligaments to achieve optimal stability and mobility.

The vascular anatomy and harvesting of the medial femoral condyle flap in pigs.
Clinically, there has been increasing employment of the medial femoral condyle flap. Pigs have been employed as a model of the medial femoral condyle flap. However, related anatomical studies from the perspective of comparative medicine are rare. The objective of this study was to explore the vascular anatomy of the medial femoral condyle in pigs, explore the surgical procedure of the medial femoral condyle flap in pigs, and compare the medial femoral condyle flap in pigs and humans. ⋯ The vascular anatomy of the medial femoral condyle in pigs and that of humans exhibited great similarities. The medial femoral condyle flap in pigs was as easily harvested as that in humans. Pigs could serve as a suitable animal model for the medial femoral condyle flap.

Review Meta Analysis Comparative StudyStemmed VS stemless total shoulder arthroplasty: a systematic review and meta-analysis.
Anatomic total shoulder arthroplasty (TSA) is commonly used for glenohumeral osteoarthritis (OA) in patients with an intact rotator cuff. The aim of this study was to quantify advantages and disadvantages of the stemmed and stemless designs in terms of clinical outcome and complications. ⋯ Stemless TSA may offer minor advantages in terms of external rotation, although the clinical relevance appears doubtful. On the other hand, a lower deep infection rate was documented for stemmed implants. Overall, stemmed and stemless TSA provided good clinical results, with similar benefits in terms of clinical outcomes and complications.

Review Comparative StudyComparison of postoperative blood loss in cementless and cemented total knee arthroplasty: a systematic review.
With the advancement of porous surface processing technology, cementless total knee arthroplasty (TKA) has once again garnered attention. Cementless TKA lacks cement sealing, raising concerns regarding potential blood loss. Recently, patient blood management (PBM) protocols have been introduced to mitigate postoperative blood loss and transfusions. In this systematic review, we aimed to address whether cementless TKA leads to increased blood loss and transfusion rates as compared with cemented TKA. Additionally, we explored the impact of contemporary PBM protocols on post-TKA hemodynamics. ⋯ In the context of recent studies implementing PBM protocols, the choice of implant fixation method appears to have no relevant impact on post-TKA blood loss. Nevertheless, it is important to note that the reporting of outcomes and PBM protocols exhibit considerable variation and heterogeneity.
