Therapeutic Effect of Acetabular Fractures Using the Pararectus Approach Combined with 3D Printing Technique.
Orthopaedic surgery, 2020Co-Authors: Ruyi Zou, Jianzhong Guan, Yuzhou Xiao, Xiaotian ChenAbstract:OBJECTIVE To explore the clinical efficacy of pararectus approach combined with 3D printing technique for the surgical treatment of partial acetabular fractures. METHODS We retrospectively evaluated 33 (20 males and 13 females) patients with acetabular fractures in the period of June 2017 to December 2018. According to Judet and Letournel classification: 11 cases were of anterior column fracture, 10 cases were of double column fracture, seven fractures were of the anterior column with posterior half transverse, three fractures were of transverse fracture, and two cases were of "T" fracture. For all cases, 3D printing is used to print the acetabular model. Pre-bent reconstruction plates from the model were placed to fixate fractures via the pararectus approach. RESULTS Thirty-three patients (mean age 48 years; range, 35-63 years), included 20 men and 13 women, were treated successfully with open reduction and internal fixation by the pararectus approach. Surgery duration was 203 min on average (range: 135-245 min), and intra-operative bleeding was 1030 mL on average (range: 450-1400 mL). All patients were followed-up for 12-18 months (average,14 months); two patients (6.0%) developed postoperative Ossifying Myositis, and there are no obvious symptoms at present; one patient (3.0%) developed postoperative wound infection, and the wound completely improved by secretion culture, enhanced dressing, and effective antibiotics; all the acetabular fractures united after 12 to 16 weeks (average,13 weeks). According to the modified Merle d'Aubigne and Postel scoring system to assess the hip function: excellent in 22 cases (66.7%), good in seven cases (21.2%), and fair in four cases (12.1%). CONCLUSIONS In the treatment of partial acetabular fractures, the pararectus approach combined with 3D printing technique can achieve effective reduction and fixation, decrease intraoperative hemorrhage, shorten operation time, and the internal fixation position can be properly adjusted during the operation by looking directly at the model.

Self-resolving focal non-Ossifying Myositis: a poorly known clinical and imaging entity diagnosed with MRI
Acta radiologica open, 2015Co-Authors: Vasiliki Perlepe, Benjamin Dallaudière, Patrick Omoumi, Lora Hristova, Afshin Rezzazadeh, Bruno Vande Berg, Jacques Malghem, Frédéric LecouvetAbstract:Focal Myositis is a rare benign inflammatory pseudotumor, presenting as a painful nodular mass within a muscle, and characterized by spontaneous resolution within weeks.To assess the clinical and imaging findings of focal nodular Myositis simulating a neoplasm at clinical examination, with no history of trauma.This study describes the locations and appearance at ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) of this condition in a series of five patients.MRI and US displayed a solid intramuscular "tumor" and suggested a continuum between the proximal and distal muscle fibers that appeared thickened within the nodular lesion, a sign that has been reported in Myositis ossificans. MRI showed edema in adjacent muscles and soft tissues, as well as intense enhancement of the mass. Intense vascular flows were seen at Doppler analysis. CT did not reveal the appearance of peripheral ossifications, ruling out the diagnosis of Myositis ossificans. In some patients, the diagnosis of sarcoma had been suggested as possible by the radiologist. Imaging follow-up with MRI showed complete resolution of the masses over several weeks, thus avoiding a biopsy; no recurrence was observed at long-term follow-up (more than 24 months).This paper highlights MRI and US findings in focal non-Ossifying Myositis, and emphasizes the role of MRI in suggesting this diagnosis, leading to the careful follow-up of the lesion until its resolution, and ruling out more aggressive lesions.
