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 Cite this article:
The increasing prevalence of osteoporosis in
an ageing population has contributed to older patients becoming
the fastest-growing group presenting with acetabular fractures.
We performed a systematic review of the literature involving a number
of databases to identify studies that included the treatment outcome
of acetabular fractures in patients aged >
55 years. An initial
search identified 61 studies; after exclusion by two independent
reviewers, 15 studies were considered to meet the inclusion criteria.
All were case series. The mean Coleman score for methodological
quality assessment was 37 (25 to 49). There were 415 fractures in
414 patients. Pooled analysis revealed a mean age of 71.8 years
(55 to 96) and a mean follow-up of 47.3 months (1 to 210). In seven
studies the results of open reduction and internal fixation (ORIF)
were presented: this was combined with simultaneous hip replacement
(THR) in four, and one study had a mixture of these strategies.
The results of percutaneous fixation were presented in two studies,
and a single study revealed the results of non-operative treatment. With fixation of the fracture, the overall mean rate of conversion
to THR was 23.1% (0% to 45.5%). The mean rate of non-fatal complications
was 39.8% (0% to 64%), and the mean mortality rate was 19.1% (5%
to 50%) at a mean of 64 months (95% confidence interval 59.4 to
68.6; range 12 to 143). Further data dealing with the classification
of the fracture, the surgical approach used, operative time, blood
loss, functional and radiological outcomes were also analysed. This study highlights that, of the many forms of treatment available
for this group of patients, there is a trend to higher complication
rates and the need for further surgery compared with the results
of the treatment of acetabular fractures in younger patients. Cite this article:
The aim of this study was to review the number of patients operated on for traumatic disruption of the pubic symphysis who developed radiological signs of movement of the anterior pelvic metalwork during the first post-operative year, and to determine whether this had clinical implications. A consecutive series of 49 patients undergoing internal fixation of a traumatic diastasis of the pubic symphysis were studied. All underwent anterior fixation of the diastasis, which was frequently combined with posterior pelvic fixation. The fractures were divided into groups using the Young and Burgess classification for pelvic ring fractures. The different combinations of anterior and posterior fixation adopted to stabilise the fractures and the type of movement of the metalwork which was observed were analysed and related to functional outcome during the first post-operative year. In 15 patients the radiographs showed movement of the anterior metalwork, with broken or mobile screws or plates, and in six there were signs of a recurrent diastasis. In this group, four patients required revision surgery; three with anterior fixation and one with removal of anterior pelvic metalwork; the remaining 11 functioned as well as the rest of the study group. We conclude that radiological signs of movement in the anterior pelvic metalwork, albeit common, are not in themselves an indication for revision surgery.
High energy fractures of the pelvis are a challenging problem both in the immediate post-injury phase and later when definitive fixation is undertaken. No single management algorithm can be applied because of associated injuries and the wide variety of trauma systems that have evolved around the world. Initial management is aimed at saving life and this is most likely to be achieved with an approach that seeks to identify and treat life-threatening injuries in order of priority. Early mortality after a pelvic fracture is most commonly due to major haemorrhage or catastrophic brain injury. In this article we review the role of pelvic binders, angiographic embolisation, pelvic packing, early internal fixation and blood transfusion with regard to controlling haemorrhage. Definitive fixation seeks to prevent deformity and reduce complications. We believe this should be undertaken by specialist surgeons in a hospital resourced, equipped and staffed to manage the whole spectrum of major trauma. We describe the most common modes of internal fixation by injury type and review the factors that influence delayed mortality, adverse functional outcome, sexual dysfunction and venous thromboembolism.
Payments by the NHS Litigation Authority continue to rise each year, and reflect an increase in successful claims for negligence against NHS Trusts. Information about the reasons for which Trusts are sued in the field of trauma and orthopaedic surgery is scarce. We analysed 130 consecutive cases of alleged clinical negligence in which the senior author had been requested to act as an expert witness between 2004 and 2006, and received information on the outcome of 97 concluded cases from the relevant solicitors. None of the 97 cases proceeded to a court hearing. Overall, 55% of cases were abandoned by the claimants’ solicitors, and the remaining 45% were settled out of court. The cases were settled for sums ranging from £4500 to £2.7 million, the median settlement being £45 000. The cases that were settled out of court were usually the result of delay in treatment or diagnosis, or because of substandard surgical technique.
Crescent fracture dislocations are a well-recognised subset of pelvic ring injuries which result from a lateral compression force. They are characterised by disruption of the sacroiliac joint and extend proximally as a fracture of the posterior iliac wing. We describe a classification with three distinct types. Type I is characterised by a large crescent fragment and the dislocation comprises no more than one-third of the sacroiliac joint, which is typically inferior. Type II fractures are associated with an intermediate-size crescent fragment and the dislocation comprises between one- and two-thirds of the joint. Type III fractures are associated with a small crescent fragment where the dislocation comprises most, but not all of the joint. The principal goals of surgical intervention are the accurate and stable reduction of the sacroiliac joint. This classification proves useful in the selection of both the surgical approach and the reduction technique. A total of 16 patients were managed according to this classification and achieved good functional results approximately two years from the time of the index injury. Confounding factors compromise the summary short-form-36 and musculoskeletal functional assessment instrument scores, which is a well-recognised phenomenon when reporting the outcome of high-energy trauma.
