Summary: This study provided evidence that regular hopping exercise can increase trabecular bone variables in postmenopausal women, demonstrating region-specific changes in bone remodelling. The use of 3D image registration and high-resolution peripheral quantitative computed tomography allowed for the localization of exercise-related bone adaptation.

Summary: This study developed and validated a finite-element model based on a 6-month longitudinal in-vivo HR-pQCT study to investigate the effect of mechanical stimuli on bone remodelling. The density distribution varied with mechanical signals, and some parameters showed significant correlation with experimental data. The developed model lays a good foundation for further exploration of the relationships between mechanical loading and human-bone microarchitecture.

Summary: This study provides reference data for HR-pQCT measures in a population of White adults, revealing differences between ages, sexes, and sites. Excel-based calculators were developed to compute subject-specific percentiles, z-scores, and t-scores and to plot individual outcomes on fitted curves.

Summary: This study investigated the safety and utility of impact microindentation technique in measuring bone quality during surgical procedures. The results showed that there were no significant differences in bone material strength index (BMSi) between patients with different fracture histories, indicating that BMSi may not be sensitive to osteoporosis. The study demonstrated the feasibility of intraoperative impact microindentation but called for further research to determine its ability to identify patients with inferior bone matrix quality.

Summary: High resolution peripheral quantitative computed tomography (HR-pQCT) combined with longitudinal imaging protocol and finite element analysis can aid in the early diagnosis of bone disease, and assess bone formation, resorption, and the relationship with mechanical loading. This study found that HR-pQCT can detect subtle changes in bone quantity and quality that traditional measures cannot capture.

Summary: By comparing the torsional strength of bones with different sized cortical drill defects, this study found that all defect test groups had significantly lower torque-to-failure than the intact group. The larger the drill hole size, the lower the torsional strength. Clinicians should be aware of the impact of residual bone defects on patient rehabilitation programs.

Summary: The study found that besides primary reduction, cortical bone quality may also be important for the risk of secondary displacement of distal radius fractures.

Summary: Hand grip strength is a significant predictor of osteoporosis in both women and men, with age- and sex-specific cutoff strengths for evaluation. It is a simple, cost-effective, and easy assessment method for identifying individuals at a high risk of osteoporosis.

Summary: The study refined and experimentally validated a homogenized finite element method for in vivo prediction of bone strength and stiffness at the distal segments of the radius and the tibia using a unified set of material properties. The identified material properties allowed for accurate prediction of stiffness and failure load, demonstrating excellent agreement with experimental results at both measurement sites.

Summary: The study aimed to evaluate the impact of surgery delay on knee extensor and flexor strength in ACL-deficient patients after reconstruction. It was found that delayed surgery led to a progressive reduction in postoperative strength performance, with a decrease in knee extension and flexion strength. Seeking for an early ACL reconstruction within the first 12 weeks after injury is advantageous for returning-to-play in terms of force generating capacity.

Summary: The results of this study suggest that an early and proactive grip strength training program can provide early recovery of grip strength and palmar flexion of the wrist without causing corrective loss at the fracture site.

Summary: The study aimed to analyze the mid-term outcomes of arthroscopy followed by open anatomic ligament repair surgery for acute lateral ankle sprain and found that ankle arthroscopy followed by open anatomic ligament repair is a reliable procedure, but distal rupture near the talar or calcaneal end is associated with delayed return-to-sport and inferior performance in resuming pre-injury sports level.

Summary: This study aimed to determine the effectiveness of hang cleans at eliciting PAP through a systematic evaluation of the implemented recovery interval. The results showed that hang cleans did not elicit PAP, but the relationship between individual strength levels and recovery duration may lead to contrasting optimal performance windows for different explosively trained athletes.

Summary: This study observed 17 patients with FAI and found that at 14 weeks postoperatively, although patients' subjective perceptions improved, there was no significant change in objectively measured hip strength. However, at 26 weeks postoperatively, patients' hip strength significantly increased. Therefore, more rigorous research is needed to understand the recovery process after surgical correction of FAI.

Summary: Anterior shoulder stabilization surgery is the preferred method for treating shoulder instability in athletes, but there is a lack of standardized guidelines for rehabilitation. The article discusses rehabilitation considerations and modifications for variations of anterior shoulder stabilization surgery, emphasizing the importance of individualized rehabilitation and integration of core and lower extremity exercises, as well as presenting the rationale for criteria-based return to sports assessments.
