R Adams Cowley Shock Trauma Center, Department of Orthopaedics, University of Maryland, School of Medicine, 6th Floor, Suite 300, 110 S. Paca St, Baltimore, MD 21201, United States. Electronic address:

In polytrauma patients with unstable pelvic ring injuries, pelvic binders interfere with femoral arterial access and are frequently removed for emergent endovascular and abdominal procedures. The 'trochanteric C-clamp' (T-clamp) is a novel technique described for rapid stabilization of the pelvis without fluoroscopic imaging, while ensuring adequate access to the groin. This case series reports the feasibility and safety following T-clamp application for unstable pelvic ring injuries in patients requiring simultaneous endovascular intervention. Read More

Acute atraumatic bilateral acetabular insufficiency fractures.

J Orthop Surg (Hong Kong) 2019 May-Aug;27(2):2309499019858574

Department of Traumatology, John Hunter Hospital and University of Newcastle, Newcastle, NSW, Australia.

Bilateral acetabular fractures have been documented in the setting of high-energy trauma, but few reports regarding atraumatic bilateral acetabular fractures exist. The following is a case report of bilateral insufficiency acetabular fractures which occurred acutely in the absence of trauma in a 49-year-old female. The case highlights the importance of perioperative awareness of those patients at significant risk of insufficiency fractures and offers a relatively elegant, less invasive solution for early mobilization in the context of acetabula insufficiency fractures.

Introduction of a three-dimensional computed tomography measurement method for acetabular fractures.

PLoS One 2019 19;14(6):e0218612. Epub 2019 Jun 19.

Department of Surgery, Subdivision of Trauma Surgery, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.

Introduction: Acetabular fractures consist of complex fracture patterns whereby bone fragments are displaced in different directions. Two-dimensional computed tomography (2DCT) gap and step-off measurements tend to underestimate the multidirectional features of these fractures. The aim was to develop a three-dimensional computed tomography (3DCT) measurement method for acetabular fractures and validate whether this method will provide an observer independent fracture characterization.

Supine versus lateral position for accurate positioning of acetabular cup in total hip arthroplasty using the modified Watson-Jones approach: A randomized single-blind controlled trial.

Orthop Traumatol Surg Res 2019 09 14;105(5):915-922. Epub 2019 Jun 14.

Department of Orthopaedic Surgery, Medical Hospital, Tokyo Medical and Dental University, 1-5-45 Yushima, Bunkyo-ku, 113-8519 Tokyo, Japan.

Background: The orientation of the acetabular cup is a critical factor for prevention of various postoperative complications in total hip arthroplasty (THA). Although most patients are treated in either supine or lateral position during surgery, it is still unclear which position is superior to achieve more accurate cup positioning. Our study was conducted in order to answer the following questions: (1) does the supine position provide a higher accuracy of cup positioning than the lateral position in THA using modified Watson-Jones approach? (2) is there any difference in the distribution of cup position between the two positions? Hypothesis Our hypothesis was that the supine position would provide a higher accuracy of cup positioning than the lateral position in THA using modified Watson-Jones approach. Read More

Technical Considerations and Fluoroscopy in Percutaneous Fixation of the Pelvis and Acetabulum.

J Am Acad Orthop Surg 2019 Dec;27(24):899-908

From the University of British Columbia, Vancouver, British Columbia, Canada (Dr. Banaszek and Dr. Lefaivre), Department of Orthopaedics, Vancouver General Hospital, Vancouver, British Columbia, Canada (Dr. Banaszek and Dr. Lefaivre), the University of Texas Southwestern Medical Center, Dallas, TX (Dr. Starr), and Parkland Memorial Hospital, Dallas, TX (Dr. Starr).

Surgical treatment of the pelvic ring and acetabulum continues to evolve. Improved imaging technology and means for closed reduction have meant that percutaneous techniques have gained popularity in the treatment of the pelvic ring and, more recently, in the acetabulum. Potential benefits include decreased soft-tissue dissection, blood loss, and surgical time. Read More

ALDI (Anterior Lateral Decubitus Intermuscular) approach to the hip: Comprehensive description of the surgical technique with operative video.

Orthop Traumatol Surg Res 2019 09 6;105(5):923-930. Epub 2019 Jun 6.

Department of Orthopaedics and Traumatology, Siena University Hospital, Viale Bracci n°16, 53100 Siena, Italy. Electronic address:

The direct anterior approach to the hip is judged to be difficult and even after many solutions, such as special operating tables, have been proposed to perform it, in some reports the complication rate remains high. The complications reported are nerve lesions, dislocation, muscles damages, intraoperative fractures. We describe a modification of the anterior approach, undertaken keeping the patient in lateral decubitus, in order to gain a better range of leg movement and a significant reduction of the force applied to the retractors, the technique was named ALDI (anterior lateral decubitus intermuscular) approach.

Standard and Advanced Imaging of Hip Osteoarthritis. What the Radiologist Should Know.

Semin Musculoskelet Radiol 2019 Jun 4;23(3):289-303. Epub 2019 Jun 4.

Department of Radiology, AdventHealth, Orlando, Florida.

Osteoarthritis (OA) of the hip is caused by degeneration of articular cartilage and the underlying bone and can be divided into two types: primary (associated with advancing age) and secondary (subsequent to fractures, avascular necrosis, infection, developmental dysplasia, and femoroacetabular impingement). Radiography remains the first-line imaging modality for diagnosing and monitoring OA, due to its accessibility, low cost, and ease of interpretation. Kellgren-Lawrence and Tönnis classification systems are radiographic OA grading systems used primarily in research, and they reflect the degree of joint space narrowing, sclerosis, cysts, deformity of the femoral head and acetabulum, and osteophytes.

Acetabular avascular necrosis following high-dose steroid treatment and chemotherapy for leukemia : Computer tomography analysis of treatment with impaction bone grafting.

Skeletal Radiol 2020 Jan 28;49(1):147-154. Epub 2019 May 28.

Discipline of Orthopedics & Trauma and Centre for Orthopaedic and Trauma Research, The University of Adelaide, Adelaide, SA, 5000, Australia.

Avascular necrosis (AVN) of the bone is thought to be a serious complication of treatment for acute lymphoblastic leukemia (ALL). The acetabulum is an unusual area to be affected by AVN, and there are currently no reports of successful joint salvage procedures found in the literature. We present a case of a 20-year-old man with ALL who was diagnosed with debilitating AVN of both acetabula 2 years following initial diagnosis of ALL and treatment with a multi-agent chemotherapy regimen including high-dose corticosteroids.

Imaging Acetabular Fractures.

Radiol Clin North Am 2019 Jul 1;57(4):823-841. Epub 2019 Apr 1.

Department of Orthopaedics, University of Maryland School of Medicine, R Adams Cowley Shock Trauma Center, 22 South Greene Street, Baltimore, MD 21201, USA.

Acetabular fractures are encountered by radiologists in a wide spectrum of practice settings. The radiologist's value in the acute and long-term management of acetabular fractures is augmented by familiarity with systematic computed tomography-based algorithms that streamline and simplify Judet-Letournel fracture typing, together with an appreciation of the role of imaging in initial triage, operative decision making, postoperative assessment, prognostication, and evaluation of complications. The steep increase in incidence of acetabular fractures in the elderly over the past several decades places special emphasis on familiarity with geriatric fracture patterns. Read More
