Background Computed tomography (CT) is superior to conventional radiography (CR) for assessing internal fixation of pelvic fractures, but with a higher radiation exposure. Low-dose CT (LDCT) could possibly have a sufficient diagnostic accuracy but with a lower radiation dose. Purpose To compare postoperative diagnostic accuracy of LDCT and CR after open reduction and internal fixation of pelvic fracture. Material and Methods Twenty-one patients were examined with LDCT and CR 0-9 days after surgery. The examinations were reviewed by two musculoskeletal radiologists...

Kite surfing has become an increasingly popular recreational activity worldwide. Thrill seekers can span the water at high speeds and reach great heights risking injury and death. We report the case of a young kite surfer who sustained a fracture dislocation of the right acetabulum that required specialised surgical management. We present this case with a review of the literature outlining the incidence of pelvic and acetabular fractures in the kitesurfing community. Overall, there is a low incidence of pelvic fractures in comparison with other orthopaedic traumas reported among kite surfers, and the most commonly injured sites are the foot and ankle...

Introduction: Hip fractures in the elderly pose an increasing problem in society. In the elderly, a bipolar hemiarthroplasty (HA) remains the treatment of choice in case of hip fractures related to osteoporosis. However, due to an ongoing osteoporosis in this age group, a periprosthetic femoral fracture and a fracture of the unresurfaced acetabulum are increasingly noticed.In the literature, no information can be found regarding the treatment options for this kind of periprosthetic acetabular fracture...

BACKGROUND: Highly cross-linked polyethylene (XLPE) is reported to have low rates of linear and volumetric wear at 10-14 years. In a prior study, larger (36 and 40 mm) femoral heads were associated with more volumetric wear, but there were only 12 hips with these heads. METHODS: We evaluated 107 hips (93 patients, with a mean age of 76 years) with one design of uncemented acetabular component, a 36 (90 hips) or 40 mm (17 hips) metal femoral head, and one electron beam 100 kGy irradiated and remelted XLPE at a mean follow-up of 8 years (range 5-13 years)...

BACKGROUND: Literature regarding surfing injuries is scarce and most studies report a high number of minor injuries. Recent literature suggests that musculoskeletal injuries are more common than previously reported. In the mid 2000s, competitive surfing has seen an increase in aerial maneuvers, as they have become more highly rewarded by the judging panel, which may be contributing to a change in injury patterns. Our goal was to evaluate orthopedic injuries in professional surfers. HYPOTHESIS: Orthopedic injuries in professional surfers are diverse and have evolved with skill and technology...

An 80-year-old woman presented to our department with visible haematuria and stage II acute kidney injury (AKI). She had stage IIB cervical cancer, for which she received chemotherapy and external beam radiotherapy in 2003. Four years later, she had a left dynamic hip screw for an extracapsular neck of femur fracture following a fall. In 2010, she underwent a right total hip replacement owing to osteoarthritis, and it was subsequently revised in 2012 owing to a right acetabular component failure. In this admission, her AKI improved with intravenous fluid administration and her haematuria settled following catheterisation with a three-way catheter and bladder irrigation with saline...

Ceramic-on-ceramic articulation shows the lowest wear, with a low incidence of osteolysis. A small cup limits options regarding liner thickness and femoral implant size. The purpose of this study was to evaluate the safety of a 4-mm-thick ceramic liner and the outcomes of cementless total hip arthroplasty using a 44- or 46-mm metal shell and a ceramic-on-ceramic bearing at mid- to long-term follow-up. Between May 2003 and June 2008, 80 patients (88 hips) who had hip osteoarthritis and a hypoplastic acetabulum underwent cementless total hip arthroplasty using a 44- or 46-mm metal shell and a ceramic-on-ceramic bearing...

Jae Hoon Jang, Nam Hoon Moon, Ki Young Park
Although surgical techniques for treating acetabular fracture are evolving, the use of periacetabular screws is common, and their placement in acetabular surgery is still technically demanding. For instance, intraarticular screw perforation is a serious complication that may occur during surgical treatment of an acetabular fracture. Here, we describe the case of a 50-year-old female who experienced an intraarticular screw perforation after surgical treatment of a posterior acetabular wall fracture. Removal of the perforated screw was performed arthroscopically based on its ability to offer minimally invasive access to the hip joint...

This is a retrospective review of two adult siblings with osteogenesis imperfecta (OI) type III (according to Sillence classification), who sustained a spontaneous femoral neck fracture and subsequent nonunion. The diagnosis of OI in these two patients was made based on clinical, radiological and genetic findings. The fracture was most likely caused by femoroacetabular impingement secondary to OI induced acetabular protrusio. A valgus osteotomy according to Pauwels'principles and fixation of the osteotomy and nonunion with a locking plate resulted in healing despite compromised bone quality and limited bone stock...
