Biomechanical analysis of anterior pelvic ring fractures with intact peripelvic soft tissues: a cadaveric study.
Biomechanical studies of the pelvis are usually performed using dissected pelvic specimens or synthetic bones. Thereby the stabilising effect of the surrounding soft tissues is analysed insufficiently. Biomechanical data for isolated anterior pelvic ring fractures are currently missing. Therefore, the purpose of this study was to develop a novel testing device for biomechanical analyses of the pelvis and to investigate two different anterior pelvic ring fractures in a cadaveric model with intact peripelvic soft tissues. ⋯ The developed test device was successfully used for biomechanical analyses of the pelvis with intact peripelvic soft tissues. In a first study, isolated unilateral fractures of the anterior pelvic ring showed no relevant biomechanical variation compared to the intact situation under isolated axial load. Only 7% of the measured stiffness was created by both unilateral pubic rami. Therefore, the clinical practice to treat unilateral anterior pelvic ring fractures conservatively is supported by the results of this study.

Mobility and mortality of 340 patients with fragility fracture of the pelvis.
To investigate prognosis of patients with fragility fracture of the pelvis (FFP) treated in a single trauma unit in Japan. ⋯ According to our data, 4.7% of patients were indicated for surgery, and only < 40% of patients were able to regain their pre-injury standing and walking abilities at 1 year after the injury. FFP may greatly affect an elderly's activities of daily living and may lead to prognosis similar to patients with proximal hip fractures. To regain the walking ability of patients with FFP, more aggressive indication of surgical treatment may be considered depending on the patient's background. Further examinations are necessary to determine the surgical indications and treatment protocol for FFP.

Fully threaded headless compression screw versus partially threaded cancellous lag screw in medial malleolus fractures: clinical and radiological outcomes.
The aim of this study was to evaluate the clinical and radiological results of medial malleolar fractures, which were treated with fully threaded headless compression screws and to compare the clinical and radiological results of this screws and partially threaded cancellous lag screws. ⋯ The results of this study showed satisfactory results in the two fixation techniques in medial malleolar fractures. However, the rates of medial sensitivity associated with implant irritation were lower in the group where fully threaded headless compression screws were used. Therefore, to prevent postoperative patient dissatisfaction caused by persistent medial sensitivity associated with implant irritation, despite successful surgical treatment, the primary choice may be fully threaded headless compression screws.

Functional treatment strategy for fragility fractures of the pelvis in geriatric patients.
We propose a functional treatment strategy for fragility fractures of the pelvis (FFP) in geriatric patients; patients with such fractures normally undergo 10 days of conservative therapy with full-weight bearing within pain limits. Conservative therapy for FFP is continued for patients who can stand with assistance, and surgical stabilization is recommended for patients with difficulty in auxiliary standing at 10 day postadmission. This study aimed to compare the outcomes of functional treatment between geriatric patients with FFP type I/II and those with FFP type III/IV, as described by Rommens et al. METHODS: We conducted a retrospective study of 84 geriatric patients who underwent functional treatment for FFP. Based on the results of the first examination, the patients were allocated to the following FFP types: type I/II (n = 53) and type III/IV (n = 31). Change in functional mobility scale described by Graham et al. from before injury to the final follow-up were compared between the groups. ⋯ The outcomes of the functional treatment for FFP for the geriatric patients did not differ significantly between the radiographic classifications. Functional treatment could, therefore, be a treatment option for almost all radiographic types of FFP, especially for geriatric patients. Further investigations are warranted.
