Zhongguo Xiu Fu Chong Jian Wai Ke Za Zhi 2021 Jun;35(6):684-689

Department of Orthopedics, Shanxi Bethune Hospital, Taiyuan Shanxi, 030032, P.R.China.

Objective: To find the ideal position of lag screw internal fixation in the anterior column of acetabulum by digital technology, and measure its related parameters, so as to improve the accuracy of lag screw implantation.

Methods: The CT scan data of 266 semi-pelvic raw in 133 cases (78 males and 55 females, aged 18-65 years old with an average age of 42 years) were collected between January 2019 and January 2020 to compose three-dimensional models. According to the relationship between the peripheral bone cortex of the anatomical channel and the lag screw, a new standard for the ideal position of lag screw fixation in the anterior column of acetabulum was proposed to simulate the implantation of the screw.

Which radiograph is most accurate for assessing hip joint penetration in infra-acetabular screw placement?

Medicine (Baltimore) 2021 Jun;100(24):e26392

Department of Orthopedic Surgery, Korea University Guro Hospital, Korea University Medical Center, Seoul, Republic of Korea.

Abstract: Although infra-acetabular screws have been used for anterior and posterior column transfixation, a screw penetrating the hip joint can result in harmful complications. However, the most accurate intraoperative radiologic imaging tool for identifying articular penetration has not been established. The purpose of the present study was, therefore, to evaluate the consistency with which standard pelvic radiographs compared with computed tomography (CT) can be used for demonstrating articular penetration.

BMC Musculoskelet Disord 2021 Jun 14;22(1):544. Epub 2021 Jun 14.

Department of Orthopedic Surgery, Musculoskeletal Research Center, Chang Gung Memorial Hospital, Chang Gung University, 5, Fu-Hsin St. Kweishan, 33302, Tao-Yuan, Taiwan.

Background: Although the incidence, types, and radiological outcomes of simultaneous ipsilateral pelvic ring and acetabular fractures have been reported, there have been no reports on factors that may affect the quality of acetabular fracture reduction.

Acetabular Stress Fracture in a Healthy Male Amateur Endurance Runner. A Case Report.

J Orthop Case Rep 2020 May-Jun;10(3):85-87

Department of Orthopaedic Surgery, San Fernando General Hospital, Independence Ave, San Fernando, Trinidad, West Indies.

Introduction: Stress fractures are overuse injuries resulting from repetitive submaximal loading of a bone. Acetabular stress fractures while highly uncommon can occur in those undergoing intense endurance training as is the case with military recruits. Diagnosis of this injury can be dubious at times, with magnetic resonance imaging (MRI) being the most sensitive diagnostic tool considering the lower sensitivity of plain film radiography.

Management of peri-prosthetic joint infection and severe bone loss after total hip arthroplasty using a long-stemmed cemented custom-made articulating spacer (CUMARS).

BMC Musculoskelet Disord 2021 Apr 16;22(1):358. Epub 2021 Apr 16.

Brighton and Sussex University Hospitals, Brighton, UK.

Background: There is little evidence on techniques for management of peri-prosthetic infection (PJI) in the context of severe proximal femoral bone loss. Custom-made articulating spacers (CUMARS) utilising cemented femoral stems as spacers was described providing better bone support and longer survival compared to conventional articulating spacers. We retrospectively report our experience managing PJI by adaptation of this technique using long cemented femoral stems where bone loss precludes use of standard stems. Read More

Feasibility of Imaging-Based 3-Dimensional Models to Design Patient-Specific Osteosynthesis Plates and Drilling Guides.

JAMA Netw Open 2021 02 1;4(2):e2037519. Epub 2021 Feb 1.

3D Lab, University of Groningen, University Medical Center Groningen, Groningen, the Netherlands.

Importance: In acetabular fracture surgery, achieving an optimal reconstruction of the articular surface decreases the risk of osteoarthritis and the subsequent need for total hip arthroplasty. However, no one-size-fits-all osteosynthesis plate is available owing to differences in fracture patterns and variations in pelvic anatomy. Currently, osteosynthesis plates need to be manually contoured intraoperatively, often resulting in inadequate reduction and fixation of the fractured segments. Read More

[Fixation of acetabulum posterior column fracture, arthroscopy assisted].

Acta Ortop Mex 2020 Jul-Aug;34(4):222-227

Servicio de traumatología y ortopedia. Unidad Médica de Alta Especialidad, Centro Médico Nacional de Occidente, Instituto Mexicano del Seguro Social. Guadalajara, Jalisco, México.

Arthroscopic surgery of the hip has evolved significantly over the last years, offering an opportunity of treatment in several intra-articular pathologies. Recent methods and instrumental advances have allowed more frequent use of this procedure, with various indications such as: hip pain, acetabular labrum lesions, extraction of foreign bodies, debridement in septic arthritis, pincer impingement, and some extra-articular injuries. Another intra-articular hip pathology that benefits from arthroscopic assistance could be found in the management of simple acetabular fractures. Read More

Transverse and transverse-variant acetabular fractures with ipsilateral sacroiliac joint injuries: A technical note for reduction and stabilization.

Injury 2021 Apr 2;52(4):1083-1088. Epub 2021 Jan 2.

McGovern Medical School at UTHealth Department of Orthopedic Surgery, Houston, TX, USA.

Transverse and T-type acetabular fractures are high energy fractures that may be associated with a disruption of the pelvic ring. While several studies report upon clinical findings and outcomes associated with combination injuries of the pelvic ring and acetabulum, there are limited reports discussing surgical treatment strategies for reduction and stabilization. Herein we focus on describing reduction and stabilization techniques of transverse or transverse-variant acetabular fractures with an associated ipsilateral partial disruption of the sacroiliac joint.
