Purpose: The wrist is involved early in rheumatoid arthritis and is often severely affected. A stable wrist is crucial to good hand function, which often necessitates a fusion. One of the most commonly used techniques in rheumatoid patients is the Mannerfelt arthrodesis. In this retrospective study the outcome and the patient's subjective satisfaction are presented and compared to other techniques. Also the influence of the position of the wrist following a fusion procedure is analysed.
Methods: Thirty-four wrists were retrospectively analysed using radiological measurements, functional scores such as the Disabilities of the Arm, Shoulder and Hand (DASH) and a pain assessment. The objective function of the hand with the fused wrist was assessed.
Results: In 92.6% of wrists the patients rated their satisfaction as good or excellent. The mean DASH score post-operatively was 63.3. Of the wrists, 17 were fixed in a median flexed position of 13° and 17 wrists in a median extended position of 8°. There was no statistically significant correlation between the position of the wrist and the satisfaction or objective function. The rate of fusion was 94.1%.
Conclusions: The Mannerfelt arthrodesis achieves good results and provides a high rate of satisfaction and pain relief in our study. It has major advantages compared to other wrist fusion techniques in the rheumatoid patient. We could not show clear statistical evidence for better results in either a flexed or an extended position, but the ratings of the patients indicated better subjective results with a slightly extended position of the arthrodesis.

Introduction: Olecranon fractures account for 5-7% of elbow fractures, making them a common injury. The majority of these fractures are treated surgically because they are intra-articular and can disrupt the elbow extensor mechanism. Mayo Type II fractures are displaced with a stable ulnohumeral joint, indicating intact ligamentous structures, particularly the anterior portion of the medial collateral ligament.

Left-right asymmetry of the human brain is widespread through its anatomy and function. However, limited microscopic understanding of it exists, particularly for anatomical asymmetry where there are few well-established animal models. In humans, most brain regions show subtle, population-average regional asymmetries in thickness or surface area, alongside a macro-scale twisting called the cerebral petalia in which the right hemisphere protrudes anteriorly past the left.

Context: To further improve rehabilitation programs while preventing overstretching the anterior cruciate ligament (ACL), a thorough understanding of the knee kinematics and ACL length change during closed kinetic chain and open kinetic chain (OKC) exercises is essential. The measurement of ACL graft length relates to the changes in strain experienced by the ACL graft during different types of exercises rather than simple physical length.
Objective: This study aimed to determine the effects of closed kinetic chain and OKC exercises on tibiofemoral kinematics and ACL graft length changes following double-bundle ACL reconstruction.

Electron backscatter diffraction (EBSD) has developed over the last few decades into a valuable crystallographic characterisation method for a wide range of sample types. Despite these advances, issues such as the complexity of sample preparation, relatively slow acquisition, and damage in beam-sensitive samples, still limit the quantity and quality of interpretable data that can be obtained. To mitigate these issues, here we propose a method based on the subsampling of probe positions and subsequent reconstruction of an incomplete data set.
