Aims. The aim of this study is to evaluate whether acetabular retroversion (AR) represents a structural anatomical abnormality of the pelvis or is a functional phenomenon of pelvic positioning in the sagittal plane, and to what extent the changes that result from patient-specific functional position affect the extent of AR. Methods. A comparative radiological study of 19 patients (38 hips) with AR were compared with a control group of 30 asymptomatic patients (60 hips). CT scans were corrected for rotation in the axial and coronal planes, and the sagittal plane was then aligned to the anterior pelvic plane. External rotation of the hemipelvis was assessed using the superior iliac wing and inferior iliac wing angles as well as
We utilized a dry-bone model of the pelvis and proximal femur, set upon transparent Lucite plates with four mounting screws and adjustable struts, allowing measurable and reproducible pelvic tilt and rotation. Our protocol for osteotome placement at each of the osteotomy sites strictly followed the technique described by Ganz. A 30°, 15 mm bifid osteotome was used for imaging at the initial ischial osteotomy at the infracotyloid groove. A 30°, 2 cm straightedge osteotome was placed 4 cm below the pelvic brim to image the retroacetabular osteotomy on the
This study compared the quality of reduction
and complication rate when using a standard ilioinguinal approach and
the new pararectus approach when treating acetabular fractures surgically.
All acetabular fractures that underwent fixation using either approach
between February 2005 and September 2014 were retrospectively reviewed
and the demographics of the patients, the surgical details and complications
were recorded. . A total of 100 patients (69 men, 31 women; mean age 57 years,
18 to 93) who were consecutively treated were included for analysis.
The quality of reduction was assessed using standardised measurement
of the gaps and steps in the articular surface on pre- and post-operative
CT-scans. . There were no significant differences in the demographics of
the patients, the surgical details or the complications between
the two approaches. A significantly better reduction of the gap,
however, was achieved with the pararectus approach (axial: p = 0.025,
coronal: p = 0.013, sagittal: p = 0.001). . These data suggest that the pararectus approach is at least equal
to, or in the case of reduction of the articular gap, superior to
the ilioinguinal approach. . This approach allows direct buttressing of the dome of the acetabulum
and the
The most widely used classification system for
acetabular fractures was developed by Judet, Judet and Letournel over
50 years ago primarily to aid surgical planning. As population demographics
and injury mechanisms have altered over time, the fracture patterns
also appear to be changing. We conducted a retrospective review
of the imaging of 100 patients with a mean age of 54.9 years (19
to 94) and a male to female ratio of 69:31 seen between 2010 and
2013 with acetabular fractures in order to determine whether the
current spectrum of injury patterns can be reliably classified using
the original system. Three consultant pelvic and acetabular surgeons and one senior
fellow analysed anonymous imaging. Inter-observer agreement for
the classification of fractures that fitted into defined categories
was substantial, (κ = 0.65, 95% confidence interval (CI) 0.51 to
0.76) with improvement to near perfect on inclusion of CT imaging
(κ = 0.80, 95% CI 0.69 to 0.91). However, a high proportion of injuries
(46%) were felt to be unclassifiable by more than one surgeon; there
was moderate agreement on which these were (κ = 0.42 95% CI 0.31
to 0.54). Further review of the unclassifiable fractures in this cohort
of 100 patients showed that they tended to occur in an older population
(mean age 59.1 years; 22 to 94 vs 47.2 years; 19
to 94; p = 0.003) and within this group, there was a recurring pattern
of anterior column and
Operative approaches to the acetabulum are generally classified into anterior, posterior, extensile or combined approaches. The choice of approach depends upon the fracture pattern and the amount of relative displacement affecting the anterior and posterior bony structures. Occasionally, extensile or combined surgical approaches are indicated for the treatment of complex fracture patterns with extensive involvement of both the anterior and posterior acetabular anatomy. However, it is believed that these approaches may be associated with higher complication rates than more limited surgical approaches. The ilioinguinal approach described by Letournel is routinely employed in the treatment of anterior column, anterior wall, anterior column/posterior hemi- transverse and certain associated both-columns, transverse and T-type fractures. The utility of this approach is sometimes limited by difficulty in visualising, reducing and applying instrumentation to the
Purpose: The age of patients presenting with acetabular fracture has increased over the last ten years. Older patients tend to have patterns involving the anterior column with comminution of the
Background: Surgical approaches to the acetabular fracture present a challenge for most surgeons. The ilioinguinal approach by Letournel has fundamentally contributed to the successful treatment of such fractures. The current tendency is to minimize the approach while maintaining a proper visual field that allows inspection of fracture fragments and the ability to reduce them. The Stoppa approach is a less invasive anterior intra-pelvic approach that could be combined with a lateral window of the ilioinguinal approach, especially helpful in facilitating the approach to the

Injuries to the lower urinary tract are well recognized following fractures to the pelvic ring. The overall incidence of pelvic fractures is similar in men and women. However associated urological injuries occur less frequently in women. There are very few reported cases of combined bladder and urethral injury or combined intra- and extraperitoneal bladder rupture in women. Only two cases have been reported describing communication of the hip joint and an extra peritoneal bladder rupture. To our knowledge we are the first to describe a pelvic ring injury complicated by combined intra and extra-peritoneal bladder rupture, urethral injury and direct intraperitoneal communication of the ruptured bladder with a central dislocation of the hip joint. The mechanism of bladder laceration was gross displacement of the
Posterior column plating through the single anterior approach reduces the morbidity in acetabular fractures that require stabilization of both the columns. The aim of this study is to assess the effectiveness of posterior column plating through the anterior intrapelvic approach (AIP) in the management of acetabular fractures. We retrospectively reviewed the data from R G Kar Medical College, Kolkata, India, from June 2018 to April 2023. Overall, there were 34 acetabulum fractures involving both columns managed by medial buttress plating of posterior column. The posterior column of the acetabular fracture was fixed through the AIP approach with buttress plate on medial surface of posterior column. Mean follow-up was 25 months (13 to 58). Accuracy of reduction and effectiveness of this technique were measured by assessing the Merle d’Aubigné score and Matta’s radiological grading at one year and at latest follow-up.Aims

Large acetabular bone defects encountered in revision total hip arthroplasty (THA) are challenging to restore. Metal constructs for structural support are combined with bone graft materials for restoration. Autograft is restricted due to limited volume, and allogenic grafts have downsides including cost, availability, and operative processing. Bone graft substitutes (BGS) are an attractive alternative if they can demonstrate positive remodelling. One potential product is a biphasic injectable mixture (Cerament) that combines a fast-resorbing material (calcium sulphate) with the highly osteoconductive material hydroxyapatite. This study reviews the application of this biomaterial in large acetabular defects. We performed a retrospective review at a single institution of patients undergoing revision THA by a single surgeon. We identified 49 consecutive patients with large acetabular defects where the biphasic BGS was applied, with no other products added to the BGS. After placement of metallic acetabular implants, the BGS was injected into the remaining bone defects surrounding the new implants. Patients were followed and monitored for functional outcome scores, implant fixation, radiological graft site remodelling, and revision failures.Aims

This report reviews the long-term results of treating acetabula with unusually severe problems, such as pelvic discontinuity or major column loss after failed total hip arthroplasty (THA) and reconstruction problems. Loss of acetabular bone stock results from removal of bone during the original procedure, prosthetic failure, and osteolysis. In massive structural failure, the acetabular rim,
As our understanding of hip function and disease improves, it is evident that the acetabular fossa has received little attention, despite it comprising over half of the acetabulum’s surface area and showing the first signs of degeneration. The fossa’s function is expected to be more than augmenting static stability with the ligamentum teres and being a templating landmark in arthroplasty. Indeed, the fossa, which is almost mature at 16 weeks of intrauterine development, plays a key role in hip development, enabling its nutrition through vascularization and synovial fluid, as well as the influx of chondrogenic stem/progenitor cells that build articular cartilage. The pulvinar, a fibrofatty tissue in the fossa, has the same developmental origin as the synovium and articular cartilage and is a biologically active area. Its unique anatomy allows for homogeneous distribution of the axial loads into the joint. It is composed of intra-articular adipose tissue (IAAT), which has adipocytes, fibroblasts, leucocytes, and abundant mast cells, which participate in the inflammatory cascade after an insult to the joint. Hence, the fossa and pulvinar should be considered in decision-making and surgical outcomes in hip preservation surgery, not only for their size, shape, and extent, but also for their biological capacity as a source of cytokines, immune cells, and chondrogenic stem cells.

This single-centre observational study aimed to describe the results of extensive bone impaction grafting of the whole acetabular cavity in combination with an uncemented component in acetabular revisions performed in a standardized manner since 1993. Between 1993 and 2013, 370 patients with a median age of 72 years (interquartile range (IQR) 63 to 79 years) underwent acetabular revision surgery. Of these, 229 were more than ten years following surgery and 137 were more than 15 years. All revisions were performed with extensive use of morcellized allograft firmly impacted into the entire acetabular cavity, followed by insertion of an uncemented component with supplementary screw fixation. All types of reoperation were captured using review of radiographs and medical charts, combined with data from the local surgical register and the Swedish Hip Arthroplasty Register.Aims
