This study protocol was approved by the Institutional Review Board (approved No. 14-21, T2022-0041). The present study was registered as NCT04349319 at ClinicalTrials.gov. This was a prospective case series (level of evidence II). Twenty-three elbows of 23 distal humerus fracture patients who underwent osteosynthesis with 3D preoperative planning (14 females, 9 males, mean age 61.3 years, age range 21–87) were evaluated. Written consent was obtained from all study participants. Patients were excluded if they had a previous history of traumatic arm injuries. All patients had CT images of the injured elbow taken before and 1 month after surgery. According to preoperative X-ray (posterior-anterior and lateral view) and CT scans, fractures were classified using the AO classification system. CT images were taken with tube settings of 120 kV and 100 mAS, a section thickness of 0.8 mm, and a pixel size of 0.3 × 0.3 mm (Sensation Cardiac, Siemens). Images were taken in a range of approximately 20 cm centered on the elbow joint.

This study protocol was approved by the Institutional Review Board. This was a case control study (level of evidence III). This study was registered as NCT02909647 at ClinicalTrials.gov. This study included the patients who underwent osteosynthesis with volar locking plate using 3D preoperative planning during the period from October 2015 to December 2019. The follow-up period was 6 months. Sixty-three wrists of 63 distal radius fracture patients (46 females, 17 males, mean age 65.1 years, age range 18-91) were evaluated. Written consent was obtained from all study participants. Patients under the age of 18, patients with bilateral distal radius fractures, and/or patients with a history of traumatic arm injury were excluded. We also excluded the patients who underwent osteosynthesis without using volar locking plate. All patients had CT images of the injured wrist taken before and 1 month after surgery. According to the preoperative X-ray (posterior-anterior and lateral view) and CT scans, fractures were classified using the AO classification system. CT images were taken with a tube setting of 120kV and 100mAS, a section thickness of 0.8 mm and a pixel size of 0.3×0.3 mm (Sensation Cardiac, Siemens). The CT images were taken from the metacarpal bone level to approximately 13 cm of the proximal forearm.

This study protocol was approved by our Institutional Review Board. The study protocol conformed to the ethical guidelines of the 1975 Declaration of Helsinki. This was a retrospective case control study (level of evidence III). Fifty-two wrists of 52 distal radius fracture patients who underwent osteosynthesis (38 females, 14 males, mean age 63.3 years, age range 18–91) were evaluated. All patients were treated with volar locking plates. Patients were excluded if they reported a previous history of traumatic arm injuries. For the assessment of CT images, written consent was obtained from all study participants. The patients lay down with their arms elevated over their heads and their wrists and forearms in neutral positions. CT images were taken before surgery and one month after the surgery with tube settings of 120 kV and 100 mAS and a section thickness of 0.8 mm and a pixel size of 0.3 × 0.3 mm (Sensation Cardiac, SIEMENS, Malvern, PA, USA). According to preoperative X-rays (posterior-anterior and lateral view) and CT scans, fractures were classified using the AO classification system.
