Abstract Background: Both-column acetabular fractures often require multiple plates for fixation, and the risk of internal implant failure is high. The author designed a posterior anatomic self-locking plate (PASP) to avoid the shortcomings. The stability of PASP was compared with two popular reconstruction plate fixation methods, and the influence of sitting, turning right and left on implants were explored. Methods: PASP, double reconstruction plate (DRP), and cross reconstruction plate (CRP) were assembled on the finite element model of both-column fractures of the left acetabulum. A load of 600N and a torque of 8N·m were loaded on the S1 vertebral body to detect stress and displacement changes when sitting, turning right and left. Results: The peak stress and displacement of three types of fixation methods on the left both-column fractures under three types of movements were CRP > DRP > PASP. PASP has the minimal value when turning left. The maximum peak of stress and displacement of PASP are 313.5 MPa and 1.15 mm respectively when turning right. Conclusion: PASP can provide higher stability than two reconstruction plates for both-column acetabular fractures. The rational movement after posterior DRP and PASP fixation for acetabular fracture is to turn to the ipsilateral side, which can avoid implant failure.

Abstract Background:Cases of acetabular fractures involving the quadrilateral surface are increasing annually. Quadrilateral surface surgery is complex, involves combined approaches, and the quality of fracture reduction closely depends on the surgical procedure. This study aimed to explore the clinical effects of the anterior pelvic wall locking plate through the lateral rectus approach for treating acetabular fractures involving quadrilateral surface. Methods:A retrospective analysis of 35 patients with acetabular fractures involving the quadrilateral surface treated with anterior pelvic wall-locking plates at the First Affiliated Hospital of Soochow University from June 2016 to December 2020. Patients included 25 males and ten females; age 23-82 years, average 52.4 years. The fracture classification was based on the Letournel-Judet classification: 13 cases of double-column fractures, seven cases of T-shaped fractures, seven cases of anterior wall with posterior semi-transverse fractures, and eight cases of transverse fractures. All patients were exposed through the lateral rectus approach, and fractures were fixed with the anterior pelvic wall-locking plate combined with the reconstruction plate. The Matta imaging standard assessed the quality of fracture reduction, and hip joint function was assessed according to the modified Merled’Aubigné-Postel scoring standard. Results:Patients meeting the inclusion and exclusion criteria were followed up for 12-42 months, with an average of 26.1 months. At the last follow-up, Matta imaging evaluation showed that 24 cases were anatomically reduced (68.6%, 24/35), seven cases were satisfied (20%, 7/35), and four cases were dissatisfied (11.4%, 4/35). The satisfaction rate was 88.6% (31/35), according to the modified Merled'Aubigné-Postel scoring standard. The hip function was excellent in 23 cases, good in six cases, fair in four cases, and poor in two cases. The excellent and good rates were 82.9% (29/35). Conclusion: The acetabular fracture involving the quadrilateral surface is clearly revealed through the lateral rectus approach. The anterior pelvic wall-locking plate combined with the reconstruction plate can fix well, with satisfactory clinical effects.

Objectives The aim of this study is to describe the presentation, surgical management and perioperative outcome of cats with acetabular fractures. Methods Case records and radiographs of cats with acetabular fractures were reviewed from presentation to the end of follow-up. Surgical technique, complications, radiographic reduction and the presence of neurological deficits were recorded. Results Sixteen cats with 17 acetabular fractures met the inclusion criteria. All fractures were associated with concurrent orthopaedic injuries. All cats were either moderately or severely lame on presentation. Five fractures were stabilised using screws, wire, pins and polymethylmethacrylate, nine were repaired using a straight dynamic compression plate and three were repaired using a locking plate. Two of seven cats that were neurologically normal prior to surgery developed transient neuropraxia following surgery. There were three major complications and no minor complications. At the end of follow-up 3/16 cats had full function, whereas 13/16 had acceptable function. Conclusions and relevance All cats undergoing surgical stabilisation of acetabular fractures returned to full or acceptable function by the end of the follow-up period and there was a low number of intraoperative and short-term complications. Neurological deficits were common preoperatively, but the majority of these deficits had resolved by follow-up.

Prospective Comparative Study

Background: The objective of the study was to compare the results of conservative management and volar locking plate by assessing the functional and radiological parameters using Stewart et al. system (1) and Sarmiento’s modification of Gartland and Werley scores (2) respectively in cases of unstable distal radius fractures. Materials & Methods: This was a prospective comparative study, which included 50 cases of distal radius fractures with 32 cases in the conservative group and 18 cases in the operative group. Radiographic and functional outcomes were assessed at 2 weeks, 3 months and 6 months using Stewart et al. system and Sarmiento’s modification of Gartland and Werley scores respectively. Results: In operative group, radiological results were well to excellent results in 100% of the patients while in conservative group, 30% had excellent results, 17% had good results and 53% had fair result. At 6 months after surgery, functional results in both groups were improved. In operative group, 100% had excellent results while in conservative group 48% had excellent, 44.44% had good, and 7% had fair results. Conclusion: This study shows that volar locking plates evidently has better results in terms of achieved faster and accelerated functional recovery.
