Three-dimensional printing-assisted surgical technique with limited operative exposure for both-column acetabular fractures.

Ulus Travma Acil Cerrahi Derg 2018 Jul;24(4):369-375

Department of Orthopedic Surgery, College of Medicine, Chungbuk National University, Cheongju-Korea.

Background: It is often difficult to achieve satisfactory reduction and fixation of both-column acetabular fractures owing to the complexity of the regional anatomy of the pelvis and the fracture configuration, which is commonly associated with a high degree of comminution. Herein, we describe the use of a three-dimensional (3D) patient-specific printed model of the pelvis to facilitate preoperative planning, simulate the fracture reduction procedure, and pre-contour the fixation plates for treating both-column acetabular fractures.

Methods: The 3D-printed model was constructed using a fused deposition modeling method with computed tomography images as inputs. Read More

Secure corridor for infraacetabular screws in acetabular fracture fixation-a 3-D radiomorphometric analysis of 124 pelvic CT datasets.

J Orthop Surg Res 2018 May 21;13(1):119. Epub 2018 May 21.

Department of Trauma Surgery, BG Klinikum Bergmannstrost Halle gGmbH, Merseburger Straße 165, 06112, Halle (Saale), Germany.

Background: Acetabular fracture surgery is directed toward anatomical reduction and stable fixation to allow for the early functional rehabilitation of an injured hip joint. Recent biomechanical investigations have shown the superiority of using an additional screw in the infraacetabular (IA) region, thereby transfixing the separated columns to strengthen the construct by closing the periacetabular fixation frame. However, the inter-individual existence and variance concerning secure IA screw corridors are poorly understood. Read More

Evaluation of accuracy of virtual surgical planning for patient-specific pre-contoured plate in acetabular fracture fixation.

Arch Orthop Trauma Surg 2018 Apr 24;138(4):495-504. Epub 2018 Jan 24.

Department of Mechanical Engineering, Indian Institute of Technology, New Delhi, India.

Background: Acetabular fractures are amongst the most challenging fractures to treat because of complex anatomy. Open reduction and internal fixation remains the standard treatment for displaced acetabular fractures to achieve anatomical reduction as in any other intra-articular fracture. Patient-specific pre-contoured reconstruction plate template made by a pre-operative virtual surgical planning can be useful to respect patient's morphology, reduce surgical invasiveness and simplify the surgical procedure.

Hemiarthroplasty proximal femoral endoprostheses following tumour reconstruction: is acetabular replacement necessary?

Bone Joint J 2018 Jan;100-B(1):101-108

University of Manchester, Oxford Road, Manchester, M13 9PL, UK.

Aims: Dislocation rates are reportedly lower in patients requiring proximal femoral hemiarthroplasty than for patients undergoing hip arthroplasty for neoplasia. Without acetabular replacement, pain due to acetabular wear necessitating revision surgery has been described. We aimed to determine whether wear of the native acetabulum following hemiarthroplasty necessitates revision surgery with secondary replacement of the acetabulum after proximal femoral replacement (PFR) for tumour reconstruction.

Radiographic Evaluation of Acetabular Fractures: Review and Update on Methodology.

J Am Acad Orthop Surg 2018 Feb;26(3):83-93

From the Department of Orthopaedics, Denver Health Medical Center, Denver, CO (Dr. Mauffrey and Dr. Stacy), the Department of Orthopaedics, University of Colorado, Denver (Dr. York), the Department of Orthopaedics, Hughston Clinic, Atlanta, GA (Dr. Ziran), and the Department of Orthopaedics, University of Cincinnati Medical Center, Cincinnati, OH (Dr. Archdeacon).

Despite increased availability of modern imaging techniques, plain radiographs remain the initial step in the classification of acetabular fractures. The ability to interpret the injury configuration allows the surgeon to develop a thorough preoperative plan and to evaluate the quality of reduction and fixation intraoperatively. Proficiency in the mental conversion of a two-dimensional radiograph into a three-dimensional conceptual image is imperative. Read More

[Cartilage regeneration surgery on the hip : What is feasible?]

Orthopade 2017 Nov;46(11):928-937

Medizinische Fakultät Mannheim, Universität Heidelberg, Mannheim, Deutschland.

Localized cartilage defects at the hip are mainly caused by pre-arthritic deformities, particularly by cam-type femoroacetabular impingement (FAI). Timely elimination of symptomatic deformities can prevent further progression such as cartilage defects. As the defects mostly occur in the anterolateral part of the acetabulum, they can be easily treated either by open surgery or by arthroscopy. Read More
