An abdominal aortic aneurysm appears to be combined with aneurysmatic lesions of the common iliac arteries in 30-40% of cases. Like abdominal aortic aneurysms, aneurysms of the common iliac arteries rarely manifest themselves clinically. The lethality rate in case of rupture is comparable to that for rupture of an abdominal aortic aneurysm. During endoprosthetic repair of abdominal aortic aneurysms combined with aneurysms of the common iliac arteries, in order to prevent endoleaks and to improve the distal zone of fixation of endografts surgeons often resort to embolization of internal iliac arteries, which may lead to ischaemic postoperative complications...

STUDY DESIGN: Retrospective case series. OBJECTIVES: To assess the radiographic outcomes and complications of sacral-alar-iliac (SAI) fixation in children. SUMMARY OF BACKGROUND DATA: Pelvic fixation in children undergoing spinal deformity surgery can be challenging because of complex anatomy, compound biomechanical forces at the lumbosacral junction, and poor bone quality. METHODS: Radiographic and clinical records of 80 consecutive patients aged 18 years or younger who underwent posterior spinal fusion surgery with SAI fixation by one pediatric orthopedic surgeon and who had a minimum 2 years of follow-up (mean follow-up: 3...

STUDY DESIGN: A retrospective study. OBJECT: To investigate the rate of lumbosacral junction complication after long corrective spinal fusion for degenerative kyphoscoliosis cases with different lower instrumented vertebra (LIV) of L5, S1 (non-iliac group), and ilium (iliac group). SUMMARY OF BACKGROUND DATA: In long spinal fusion, high mechanical stress is concentrated at the fusion ends, especially at the lumbosacral junction. There are conflicting views regarding the selection of lower instrumented vertebra in long spinal fusion for adult spinal deformity...

Background Articular cartilage lesions of the talus remain a challenging clinical problem because of the lack of natural regeneration and limited treatment options. Microfracture is often the first-line therapy, however lesions larger than 1.5 cm(2) have been shown to not do as well with this treatment method. Methods The objective of this retrospective study was to evaluate the outcomes of iliac crest bone marrow aspirate concentrate/collagen scaffold (ICBMA) and particulated juvenile articular cartilage (PJAC) for larger articular cartilage lesions of the talus...

Nonunion after distal radius fracture is rare, serious and unpredictable. The preferred treatment is resection of the nonunion zone followed by open reduction and internal fixation with autologous iliac crest bone graft. When the distal fragment is less than 5mm high, a dorsal plate that bridges the radiocarpal joint is recommended. In patients with low functional demands, radiocarpal fusion is a logical choice. The bone healing rate is 58% and could be improved by using a vascular graft. Bone healing is not synonymous with good clinical outcomes...

PURPOSE: Several reports have indicated that anterior dislocation of total hip arthroplasty (THA) can be caused by spinal degenerative changes with excessive pelvic retroversion. However, no reports have indicated that posterior dislocation can be caused by fixed pelvic anteversion after corrective spine surgery. We describe a rare case experiencing repeated posterior THA dislocation that occurred at 5 months after corrective spinal long fusion with pelvic fixation. METHODS: A 64-year-old woman had undergone bilateral THA at 13 years before presenting to our institution...

BACKGROUND: Acetabular bone deficiency, especially proximal and lateral deficiency, is a difficult technical problem during primary total hip arthroplasty (THA) in developmental dysplasia of the hip (DDH). We report a new reconstruction method using a medial-reduced cemented socket and additional bulk bone in conjunction with impaction morselized bone grafting (additional bulk bone grafting method). QUESTIONS/PURPOSES: In a population of patients with acetabular dysplasia undergoing THA using a medial-reduced cemented socket and additional bulk bone with impacted morselized bone grafting, we evaluated (1) the radiographic appearance of bone graft; (2) the proportion of cups that developed loosening and subsequent revision; and (3) clinical results (outcome scores and complications)...

PURPOSE: Scaphoid nonunion can occur in both non-operative and operatively treated scaphoid fractures. Without treatment, this can lead to a predictable pattern of carpal collapse and degenerative arthritic change and patients can experience both pain and functional loss in the early and late phases of progression. An operative technique with a high success rate for union is important. This paper describes a technique for treatment of scaphoid nonunion with K-wire fixation and iliac crest cancellous bone graft...

BACKGROUND: Implantation of Kerboull acetabular reinforcement cross-plates (Kerboull plate) carries a risk for injury to vascular structures and pelvic organs. To our knowledge, there is no study assessing anatomical assessment related to this risk with this specific design. Therefore, we performed a prospective study to answer the following four questions: 1) What is the minimum distance and angle between the plate and iliac vessels? 2) What is the distance between the plate and the inner cortex of the ilium? 3) What is the ratio of views with muscle tissue present on the inner surface of the ilium? 4) What are the boundaries of the safe zone for transacetabular screw fixation for a Kerboull plate? HYPOTHESIS: A safe zone for fixation screws would be defined by a narrow range of insertion angles...

: Congenital pseudarthrosis of the clavicle (CPC) is a very rare condition with a predilection for the right clavicle. Young children are often only symptomatic with activities and as they grow. Operative management in an asymptomatic child is debatable, with various techniques reported in the literature. This is a retrospective, single-centre case series study. All children with CPC treated surgically by resection, bone grafting (nonvascular iliac crest) and plate fixation between 2004 and 2012 at our centre were included...

: From 2001 to 2015, 11 wrists in 11 patients with osteoarthritis of the wrist had failed wrist arthroplasties, which were subsequently converted to arthrodesis using intercalated corticocancellous autograft from the iliac crest and fixation with an arthrodesis plate or a customized peg. Clinical and radiological bone union was achieved in all the operated wrists. At final follow-up of ten patients after 6 years, they had a substantial reduction in pain and improvement in daily function and grip strength compared with those before arthrodesis...

PURPOSE: The obturator artery and its accessory (aberrant) arising from different origins and crossing the pubic rami are vascular variations. The internal iliac artery usually provides the obturator artery which may communicates with the external iliac artery through either the accessory obturator or inferior epigastric artery. A collateral circulation between the external and internal iliac system is known as corona mortis. The aim of current study is to provide sufficient data of vascular variability crossing the pubic rami for clinical field...

In scaphoid fractures, delayed diagnosis and nonunion are fairly common as a result of several factors, including the difficulty of radiographic diagnosis of non-displaced fractures and underestimation of the injury by the patient. Main factors to consider when deciding treatment are the type of fracture and fracture stability. In the stable nonunion (Type D1 according to the Filan and Herbert classification, or linear type of Ikeda's classification), percutaneous screw fixation without bone graft is recommended...
