Summary: This study found that implant failure is common in small animal orthopedics and is associated with abnormal fracture healing. Among the cases studied, 23% experienced implant failure, which was significantly associated with delayed union, malunion, or non-union.

Summary: The study focused on evaluating the effect of modified shoulder bolts on fracture site motion during dynamic loading within a spatial frame. Results indicated that using modified shoulder bolts can allow for dynamization of the spatial frame without increasing shear motion.

Summary: This study investigated the biomechanics of sheep mandibles as a preclinical model for testing mechanical strength of fixation devices and biomechanical environment induced on mandibular fractures. Results showed differences in mechanical environments and stress between human and sheep mandibles, suggesting careful consideration when using sheep mandibles for studying the effect of fixation devices on healing outcome.

Summary: Femur diaphysis fractures usually require surgery and the recovery process can be lengthy. Current assessment methods for femur healing are qualitative and rely on clinical experience. This paper presents a methodology using fibre Bragg grating sensors to assess femur healing, which is validated through numerical analysis and experimental testing with composite femur samples. The results demonstrate that the strain values measured by FBGs can effectively distinguish different healing conditions and may have potential for assessing long bone fractures in patients of different ages and recovery rates.

Summary: This study investigates the influence of uncertainty and variability on the healing outcomes of distal radius fracture (DRF) treated with the volar locking plate (VLP). The study finds that the titanium VLP is a strong and ductile fixation that requires optimized designs and configurations for early fracture stabilization. The study also highlights the negative impact of uncertainty in fracture geometry and physiological loading on early DRF healing.

Summary: The study designed a cross-inverted triangular pattern for the treatment of femoral neck fractures and compared the biomechanics of compression screw nails inserted in cross-inverted triangular patterns and inverted triangular patterns. The results showed that the cross-inverted triangular hollow threaded nail had better conductivity and more stable fixation, suitable for the fixation of subhead and trans-neck femoral neck fractures. However, its stability in fixation of basal femoral neck fractures was worse than that of the inverted triangular pattern.

Summary: Doses of irradiation above 25 kGy are known to cause irreversible mechanical decay in bone tissue. However, the impact of irradiation doses absorbed in a clinical setting on the mechanical properties of bone remains unclear. This study investigated high irradiation doses of 31.2 kGy and found that they severely alter the mechanical properties of bone, while doses below 30 Gy do not have an impact on mechanical bending-behavior of bone.

Summary: The biomechanical environment is crucial for fracture repair, regulating biological activities and tissue formation through mechanical signals. Manipulating mechanobiology at the fracture site through fracture fixation design and weight-bearing can influence the healing response. Parameters like fracture gap size, interfragmentary movement, strain, and deformation as well as externally applied movement play important roles in fracture repair process.

Summary: This study compared the clinical and biomechanical outcomes of INFIX plus single and double sacroiliac screw fixation for Type C unstable pelvic fractures. The biomechanical study showed that INFIX plus double sacroiliac screw fixation provided better stability. The clinical case series demonstrated that INFIX plus double sacroiliac screw fixation had better functional outcomes and higher radiographic satisfaction rate compared to INFIX plus single sacroiliac screw fixation.

Summary: This study compared the biomechanical properties of compression buttress screw (CBS) fixation with three plate fixation methods for the treatment of vertical femoral neck fractures (FNFs). The results showed that the biomechanical parameters of CBS fixation were comparable to anteromedial plate fixation (AMP) and medial buttress plate fixation (MBP), and demonstrated superior axial stiffness than medial buttress plate fixation without proximal screw (MBPw).

Summary: This study developed a finite element model of dynamic compression plating and examined the effects of surgical variables on fracture compression and postoperative stability. The model predictions showed good agreement with experimental results, and revealed that plate prebend can eliminate gaps but also lead to a sharp decrease in compression force.

Summary: The study investigated the short-term response of healing tissue to mechanical stimulation, finding that resting phase may play a crucial role in bone healing progression. Optimizing the ratio between stimulation and resting periods could contribute to more robust fracture healing in the future.

Summary: Expandable pedicle screws have advantages in treating lumbar spine fractures, but there is a lack of preclinical investigations on their use in lumbar vertebrae. This study compared the stress-strain distribution of normal and expandable pedicle screws, showing that the expandable screws had better fixation and stability.

Summary: Reverse total shoulder arthroplasty (RTSA) is increasingly utilized for complex proximal humerus fractures and their sequelae, with advancements in prosthesis designs and fixation techniques leading to improved tuberosity healing and better outcomes for patients. This review highlights recent evidence on RTSA design features and tuberosity fixation techniques that can impact tuberosity healing.
