REVIEW
Joong-Myung Lee, Tae-Ho Kim
The rate of acetabular cup revision arthroplasty is gradually rising along with an increased risk of osteolysis and prosthesis loosening over time and an increase in life expectancy. The goals of revision total hip arthroplasty are: i) implant stability through reconstruction of large bone defects, ii) restoration of range of motion and biomechanics of the hip joint, and iii) normalization of uneven limb lengths. In acetabular cup revision arthroplasty, stable fixation of acetabular components is difficult in the presence of severe bone loss (e...

Acetabular reconstruction aims at filling bony defects and positioning the acetabular component in its anatomical place. To this, the use of Kerboull plate would give an automatic optimal positioning while reconstructing the acetabular cavity. We developed a technique, the cross technique, that approaches acetabular reconstruction in a systematic way. It consists of placing the KP following its cross design, in reference to a vertical plane (hook, center, palette) and a horizontal plane (horizontal flanges)...

BACKGROUND: Delayed reconstruction of acetabular fractures remains a challenging task for orthopedists because of malunion, fracture line absorption, and scar formation. Accurate osteotomy, interfragmentary release, and proper adaptation of plates are keys to successful surgery. Prevention of superior gluteal artery (SGA) injury induced by cleaning of the osteotylus and reduction of the sciatic notch is also important. Therefore, sufficient preoperative planning is essential. However, traditional planning methods do not readily provide direct visual and tactile feedback to surgeons...

INTRODUCTION: The development of dual-energy CT and metal artefact reduction software provides a further chance of reducing metal-related artefacts. However, there have been only a few studies regarding whether MARs practically affect visibility of structures around a metallic hip prosthesis on post-operative CT evaluation. METHODS: Twenty-seven patients with 42 metallic hip prostheses underwent DECT. The datasets were reconstructed with 70, 90 and 110 keV with and without MARs...

BACKGROUND: Subspine impingement is a recognized source of extraarticular hip impingement. Although CT-based classification systems have been described, to our knowledge, no study has evaluated the morphology of the anteroinferior iliac spine (AIIS) with plain radiographs nor to our knowledge has any study compared its appearance between plain radiographs and CT scan and correlated AIIS morphology with physical findings. Previous work has suggested a correlation of AIIS morphology and hip ROM but this has not been clinically validated...

The incidence of acetabular fractures has increased markedly in patients over 60 in the last quarter of a century, with open reduction and internal fixation being regarded to be the treatment of choice in most patients with displaced acetabular fractures. Lower limb ischaemia following acetabular fixation or arthroplasty is rare. However, such complications can be limb or life threatening, and therefore, it is important to recognise them as early as possible. We present the case of a 70-year-old man with no significant medical history who underwent acetabular fixation with simultaneous arthroplasty complicated with bilateral lower limb ischaemia...

INTRODUCTION AND OBJECTIVES: Acetabular revision surgery is a challenge due to the appearance of bone defects that make primary fixation of implants difficult when extracting loosened components. Reinforcement rings, such as Burch-Schneider (BS), have been shown to be allies in moderate or severe bone defects. The objective of the study is to evaluate the results and survival of these types of implants in acetabular revision surgery in the medium follow-up. MATERIAL AND METHODS: Retrospective study on a cohort of 64 patients (67 replacements) with BS rings associated with morselized bone allografts in a 2 years minimum follow-up...

Hip arthroscopy is an evolving procedure and its indications have expanded. The number of patients undergoing this procedure has increased significantly as well as the number of surgeons being trained. This has resulted in a notable increase in post-operative complication rates creating the need to develop advanced hip arthroscopic techniques. Revision hip arthroscopy is often complex and many factors should be considered to achieve a satisfactory clinical outcome. Careful pre-operative planning and agreement of expectations between the physician and patient regarding the procedure are important...

BACKGROUND: The treatment of acetabular protrusions during total hip arthroplasty of patients with rheumatoid arthritis is difficult. A lack of bone stock, deficient medial cup support, and medialization of the joint center in those with protrusio acetabuli must be addressed during acetabular reconstruction. The purpose of this study was to assess the short-term clinical results of total hip arthroplasty in patients with severe acetabular protrusions secondary to rheumatoid arthritis...

Developmental dysplasia of the hip (DDH) is one of the most common diseases encountered in pediatric orthopedic departments. Current treatment strategies seek to improve acetabular coverage, the principal defect of acetabular dysplasia, but are not very successful. We developed a guided bone regeneration (GBR) strategy to improve acetabular coverage via bone tissue engineering (BTE). Poly- dl -lactide (PDLLA) membranes were seeded with bone marrow mesenchymal stem cells (BMSCs) to form a BTE complex, which was then implanted into the superior margin of the acetabulum in a rabbit DDH model...
