“…The most frequently investigated fracture types in biomechanical tests as well as in FEA were an ACPHT fracture (biomechanical tests: 11; FEA: 3) [ 36 – 44 , 60 , 63 , 66 , 71 ], a posterior column/wall fracture (biomechanical tests: 9; FEA: 2) [ 52 – 59 , 62 , 67 ], and a transverse acetabular fracture (biomechanical tests: 7; FEA: 2) [ 28 – 34 , 70 ]. Other fracture types (associated both column fracture, T-shape fracture and isolated anterior column fracture) were less frequently studied in biomechanical analyses [ 35 , 45 – 51 , 61 , 64 , 65 , 68 – 70 ]. The numbers of investigated fracture types within the reported studies are demonstrated in Fig.…”

“…A double-limb stance protocol was mainly applied with a cadaveric pelvis model and in studies evaluating posterior wall fractures or associated both column fractures (6 biomechanical test setups) [ 45 , 48 , 52 , 57 , 58 , 61 ]. In a double-limb stance model, both proximal femoral shafts of the human cadaveric pelves or synthetic pelves were rigidly fixed and the loading force was applied through the fourth lumbar vertebrae with the pelvis in a specific neutral position [ 45 , 48 , 52 , 57 , 58 , 61 ].…”

“…Both position and relative movements of the markers were usually determined by high precision cameras. Other methods that were used less frequently for the evaluation of displacement, were an ultrasound-based system in five biomechanical test setups (sensor pairs consisting of an ultrasonic microphone and an ultrasonic reader) [ 35 , 44 , 50 , 51 , 57 ], mechanical (digital) distance sensors in four biomechanical test setups (mechanical indicator measuring changes in distance using analogue or digital displays) [ 42 , 45 , 48 , 59 ] and a beam sensor in two biomechanical test setups (sensor pair determining the relative distance via a photoelectric effect) [ 45 , 48 ]. A few experiments measured the subluxation of the load transmitting femoral head with integrated displacement sensors of the biomechanical testing machine (5 of 34 biomechanical test setups) [ 34 , 43 , 47 , 52 , 53 ].…”

Purpose Optimal anatomical reduction and stable fixation of acetabular fractures are important in avoiding secondary dislocation and osteoarthritis. Biomechanical studies of treatment options of acetabular fractures aim to evaluate the biomechanical properties of different fixation methods. As the setup of the biomechanical test can influence the experimental results, this review aimed to analyze the characteristics, comparability and clinical implications of studies on biomechanical test setups and finite element analyses in the fixation of acetabular fractures. Methods A systematic literature research was conducted according to the PRISMA guidelines, using the PubMed/MEDLINE and Web of Science databases. 44 studies conducting biomechanical analyses of fixation of acetabular fractures were identified, which met the predefined inclusion and exclusion criteria and which were published in English between 2000 and April 16, 2021. The studies were analyzed with respect to distinct parameters, including fracture type, material of pelvis model, investigated fixation construct, loading direction, loading protocol, maximum loading force, outcome parameter and measurement method. Results In summary, there was no standardized test setup within the studies on fixation constructs for acetabular fractures. It is therefore difficult to compare the studies directly, as they employ a variety of different test parameters. Furthermore, the clinical implications of the biomechanical studies should be scrutinized, since several test parameters were not based on observations of the human physiology. Conclusion The limited comparability and restricted clinical implications should be kept in mind when interpreting the results of biomechanical studies and when designing test setups to evaluate fixation methods for acetabular fractures.

“…Both‐column fractures are defined as entire acetabular articular surface detachment from the axial skeleton by the Judet–Letournel classification system, with fracture lines involving multiple planes 7,8 . According to the previous literature, both‐column acetabular fractures are also commonly associated with PW fracture 9 .…”

Objective The treatment methods for posterior wall (PW) in both‐column acetabular fractures are controversial. The purpose of this study was to compare reduction quality, clinical outcomes, and complications of nonfixation for posterior wall fragment and plating via the Kocher–Langenbeck (KL) approach after anterior surgical procedures in both‐column acetabular fractures. Methods Forty‐nine patients with both‐column acetabular fractures associated with PW fixed via iliac fossa and Stoppa approaches from October 2012 to October 2017 were recruited into this study and were divided into two groups: Nonfix group (nonfixation for PW) and KL group (PW plating through the KL approach). Operation duration, intraoperative blood loss, reduction quality, fracture healing, and relevant complications of patients were reviewed. Merle d'Aubigné scores were used for assessing functional outcome. Results The mean blood loss and operation durations were lower in Nonfix group than in KL group (both p < 0.05). The mean hospital stay durations were (18.54 ± 6.42) days and (21.17 ± 7.32) days in groups Nonfix and KL, respectively (p = 0.186). All fractures healed well with no significant difference in union time between the two groups (p = 0.210). The rates of satisfactory reduction were 84.62% (22/26) in Nonfix group and 86.96% (20/23) in KL group (p = 1.000). The mean Merle d'Aubigné scores were 15.62 ± 2.28 in Nonfix group and 16.17 ± 2.19 in KL group (p = 0.388). The complication rates were 7.69% (2/26) in Nonfix group and 34.78% (8/23) in KL group (p = 0.046). Conclusions For both‐column acetabular fractures associated with PW fragment, although fixation of PW was not performed after anterior surgical procedures, satisfactory outcomes could also be obtained. However, nonfixation was a less invasive choice with a lower complication rate.

Objective: The three-dimensional (3D) force plate is a widely used device in biomechanical research, capable of measuring the ground reaction force (GRF) exerted on the sole of the foot. The forces of human joints are calculated by combining GRF with motion capture data. In the field of nursing and rehabilitation, evaluation of joint pressure can inform further therapy. However, its high cost often limits its application to a small population. Therefore, we aimed to design and manufacture a low-cost 3D force plate to address this issue, which will advance the evaluation of joint pressure in nursing practices. Methods: Through mechanical derivation and finite element method simulation, the feasibility of this 3D force plate was tested. We proposed a method based on simulation results to assist in calibration. Furthermore, we collected the GRF data of the author using the 3D force plate designed in this study. Then we imported this GRF data and the data obtained from motion capture into OpenSim. Results: The 3D force plate consisted of two 3D force sensors and a 600 300 mm board. The 3D force plate could measure the 3D reaction force between the sole of a subject’s foot and the ground. The 3D force plate was validated the usability in this study through theoretical calculation and a complete musculoskeletal analysis process. Conclusion: We have completed the design and practicality verification of this low-cost 3D force plate and provided a calibration method based on finite element method simulation assistance. Low-cost 3D force plates can accelerate the popularization and application of musculoskeletal analysis in the field of nursing and rehabilitation, which is helpful for precision health.
