INTRODUCTION: The modified Stoppa approach for acetabular fractures has become popular. However, the possibility of injury to the obturator nerve with this approach has not been sufficiently considered. We have experienced a case of nerve entrapment in severely displaced fractures. Therefore we performed a retrospective study to: 1) evaluate the incidence of obturator nerve injury in the modified Stoppa approach for acetabular fractures, 2) analyze the relationship between the extent of displacement of the quadrilateral plate and injury to the obturator nerve HYPOTHESIS: We hypothesized that obturator nerve injury would be related to a marked medial displacement of the quadrilateral plate PATIENTS AND METHODS: We conducted a retrospective cohort study of 22 patients with acetabular fractures that were surgically treated with the modified Stoppa approach...

OBJECTIVE: The aim of this study was to evaluate the biomechanical properties of common fixation systems for complex acetabular fractures. METHODS: A finite element (FE) pelvic model with anterior column and posterior hemi-transverse acetabular fractures was created. Three common fixation systems were used to fix the posterior wall acetabular fractures: 1. Anterior column plate combined with posterior column screws (group I), 2. Anterior column plate combined with quadrilateral area screws (group II) and 3...

As elderly patients with hip osteoarthritis aged, acetabular dysplasia parameters decreased (Sharp's angle, acetabular roof obliquity angle, and acetabular head index) and the incidence of the atrophic type increased. Vertebral body fracture was more frequent in the atrophic type, suggesting the involvement of osteoporosis at the onset of hip osteoarthritis. INTRODUCTION: Osteoarthritis (OA) is associated with increased bone formation at a local site. However, excessive bone resorption has also been found to occur in the early stages of OA...

PROBLEM AND HYPOTHESIS: Over time, some patients with unilateral or bilateral lumbosacral injuries experience chronic low back pain. We studied the sagittal and frontal balance in a population with these injuries to determine whether mismatch in the pelvic and lumbar angles are associated with chronic low back pain. PATIENTS AND METHODS: Patients with posterior pelvic ring fractures (Tile C1, C2, C3 and A3.3) that had healed were included. Foreign patients and those with an associated spinal or acetabular fracture or nonunion were excluded...

Bone metastases are a common finding in oncology. They often induce pain but also fractures which impair quality of life, especially when involving weight-bearing bones. Percutaneous image-guided consolidation techniques play a major role for the management of bone metastases. Cementoplasty aims to stabilize bone and control pain by injecting acrylic cement into a weakened bone. This minimally invasive technique has proven its efficacy for bones submitted to compression forces: vertebra, acetabular roof, and condyles...

BACKGROUND: The results of cementless stems in total hip arthroplasty (THA) done because of congenital dislocation with step-cut osteotomy is not well known, particularly the influence of the design and the role of extent of porous coating. Therefore we performed a retrospective study to evaluate the mid to long-term results THA performed with a single type acetabular component and different geometry and fixation type stems with ceramic bearings in the setting of step-cut subtrochanteric osteotomy in high hip dislocated (HHD) patients...

Dual-mobility cups were introduced to reduce the incidence of dislocation after total hip arthroplasty (THA). The biomechanics of dual-mobility cups allow for greater range of motion, jump distance and better stability when compared to conventional cups in THA. These cups can be very beneficial in THA particularly when the hip instability is a concern such as elderly patients, obese, hip fracture patients, those with neuromuscular diseases, or patients undergoing revision THA for instability. Areas covered: An extensive search is conducted in PubMed and Google scholar to find past five years publications relevant to dual-mobility cups in THA...

BACKGROUND: Maximizing operating room utilization in orthopedic and other surgeries relies on accurate estimates of surgical control time (SCT). A variety of case and patient-specific variables can influence the duration of surgical time during revision total hip arthroplasty (THA). We hypothesized that these variables are better predictors of actual SCT (aSCT) than a surgeon's own prediction (pSCT). METHODS: All revision THAs from October 2008 to September 2014 from one institution were accessed...

BACKGROUND: Fractures of the acetabulum in younger patients are commonly treated by open reduction and internal fixation. For elderly patients, stable primary total hip arthroplasty with the advantage of immediate postoperative mobilization might be the adequate treatment. For this purpose, a sufficiently stable fixation of the acetabular component is required. MATERIALS AND METHODS: Between August 2009 and 2014, 30 cases were reported in which all patients underwent total hip arthroplasty additionally to a customized implant designed as an antiprotrusion cage...

BACKGROUND: The psoas minor partially inserted to the superior pelvic brim. And the plate used to fix the acetabular fracture has always been positioned at the pelvic brim after reduction through the Stoppa approach. However, there are few studies depicting the clinical significance of the psoas minor. The purpose of this paper was to explore the relationship between the insertion of the psoas minor tendon at the pelvic brim (IPMTPB) and screw placement through the Stoppa approach. MATERIALS AND METHODS: Fifteen cadavers were dissected for adequate exposure to IPMTPB in our study...

OBJECTIVES: Anatomical acetabular plates were recently introduced to fix acetabular fractures via the intra-pelvic approach. Therefore we asked: I.) Does the preshaped three dimensional suprapectineal plate interfere with or even impair the fracture reduction quality? II.) How often does the anterior intra-pelvic approach need to be extended by the first (lateral) window of the ilioinguinal approach? DESIGN: Observational case series SETTING:: Two Level one Trauma centresPatients / Participants: Patients with unstable acetabular fractures in 2014 INTERVENTION:: Fracture fixation with anatomical-preshaped, three-dimensional suprapectineal plates via the anterior intra-pelvic approach ± the first window of the ilioinguinal approach...

BACKGROUND: Epidemiological studies of acetabular fractures (AFs) are scarce and, to our knowledge, the most recent one from France, by Letournel and Judet, dates back to 1993. Studies have suggested a decrease in high-energy AFs contrasting with an increase in low-energy AFs due to the longer life expectancy. However, a French case-series study failed to confirm these data. We therefore conducted a 10-year retrospective study in a level-1 trauma centre to: (1) characterise the epidemiological profile of AF; (2) and to describe the treatment strategy...

Bisphosphonates have been commonly used in the treatment of osteoporosis, demonstrating its efficacy in fracture risk reduction. However, even if are generally safe and well tolerated, concerns have emerged about atypical fractures related to its prolonged use. Although atypical femoral fracture are more common, case reports demonstrated that even other skeletal areas can be involved by unusual pattern of fracture. We report a atypical acetabular periprosthetic fracture in a 83-year-old female patient after prolonged alendronate treatment for osteoporosis and isolated acetabular revision surgery...
