Introduction: Acetabular fractures are increasing in incidence and no previous published studies have reviewed the factors influencing the outcome of operative stabilization on the neural function and recovery. The incidence, outcome and recovery of operatively managed acetabular fractures with associated neural injuries were studied from a three-year cohort of patients.

Methods: This retrospective case series study of 456 referrals to a tertiary referral unit, from 1st Jan 2004 to 31st Dec 2006, identified 29 (6.3%) acetabular fractures associated with neural injuries. The fractures were classified using the Letournel system, neural injuries classified as either complete or incomplete and the degree of post-operative skeletal displacement quantified using radiographs. A mean clinical and radiographic follow up of 3.5 years was achieved and statistical analysis was performed used chi-squared (SPSS)

Results: Overall, the cohort had a mean age of 34 years, 17 (59%) were male and the mean delay from time of injury to time of acetabular surgery was 16 days (range 4 – 53 days). All fractures involved posterior wall and/or posterior column and 23 (79%) were of the more complex, associated type, Letournel fracture patterns. Full resolution of neural symptoms was observed in 9 (31%) patients with a mean fracture reduction of 1.6mm. Partial neurological improvement was observed in 15 patients. Ongoing complete nerve palsy was observed in 5 patients, associated with a mean fracture reduction of 2.5 mm and a significantly longer delay to surgery of 32 days (p< 0.05).

Discussion: Acetabular fractures involving the posterior wall or column have a high incidence of neural injury. Accurate fracture reduction and stabilization, achieved without a prolonged delay, affords a good neural outcome for these patients. In similiar injuries with complete nerve palsy, delayed and sub-optimal surgical reduction predicts a poor prognosis.

Introduction: The incidence, outcome and recovery of operatively managed pelvic ring fractures were studied from a three-year cohort of patients. No previous published studies have reviewed the factors influencing the outcome of operative stabilization on the neural function and natural recovery in these potentially devastating injuries.

Methods: This retrospective case series study of 489 referrals to a tertiary referral unit, from 1st Jan 2004 to 31st Dec 2006, identified 42 (8.6%) patients who had sustained pelvic ring injuries with associated neural injuries. Each pelvic injury was classified using the Tile and Burgess & Young classifications, neural injuries were classified as either complete or incomplete and the degree of post-operative skeletal displacement was quantified using radiographs. A mean clinical and radiographic follow up of 3.5 years was achieved and statistical analysis was performed used chi-squared (SPSS)

Results: The mean age of patients with neural injuries was 28 years, 32 (76%) were male and 37 (88%) had unstable, Tile type C, fracture patterns. The mean delay from time of injury to time of pelvic surgery was 11 days (range 3 – 42 days). Full resolution of neural symptoms was observed in 16 (38%) patients, with a mean fracture reduction of < 6mm. Incomplete improvement was observed in 11 patients and 15 patients had ongoing complete lumbosacral palsy. Patients who failed to achieve full resolution of neural function had a mean fracture or sacro-iliac joint reduction of 8.8 mm and the mean delay to surgery was 24 days.

Discussion: Pelvic ring injuries with an unstable fracture pattern are associated with a high incidence of neural injury. Accurate fracture reduction and stabilization, achieved without a prolonged delay, creates a better environment to achieve a good neural outcome. In such injuries with complete nerve palsy, delayed and suboptimal surgical reduction predicts a poor prognosis.

We report the outcome of 161 of 257 surgically fixed acetabular fractures. The operations were undertaken between 1989 and 1998 and the patients were followed for a minimum of ten years. Anthropometric data, fracture pattern, time to surgery, associated injuries, surgical approach, complications and outcome were recorded. Modified Merle D’Aubigné score and Matta radiological scoring systems were used as outcome measures. We observed simple fractures in 108 patients (42%) and associated fractures in 149 (58%).

The result was excellent in 75 patients (47%), good in 41 (25%), fair in 12 (7%) and poor in 33 (20%). Poor prognostic factors included increasing age, delay to surgery, quality of reduction and some fracture patterns. Complications were common in the medium- to long-term and functional outcome was variable. The gold-standard treatment for displaced acetabular fractures remains open reduction and internal fixation performed in dedicated units by specialist surgeons as soon as possible.

The incidence of acetabular fractures within the UK is about 3 in 100,000 of the population per year. Since Letournel and Judet first proposed that operative reduction and rigid internal fixation of displaced fractures will likely lead to better outcome, operative management of such fractures has become standard management in major trauma centres. Long term outcome results following acetabular surgery have been reported sparingly.

Two hundred and fifty-seven displaced acetabular fractures underwent an open reduction and internal fixation at St. George’s Pelvic Unit between 1992 and 1997. All surgery was performed by a single surgeon. 161 patients were followed up prospectively for a minimum of 10 years. Those lost to follow up were excluded. Anthropometric data, fracture pattern, time to surgery, associated injuries, approach, complication and outcome recorded on a database. Modified Merle D’ Auberge score was utilized as outcome measures.

The mean age was 36 years (15 to 85). Road traffic accident was the commonest mechanism of injury. We observed simple fractures in 34 % and associated fractures in 66%. 52% suffered polytrauma. Average time to surgery was 11 days and anatomic reduction was achieved in 73.9%. Results were excellent 46.8 %, good 25.5 %, fair 7.5 %, and poor 19.2 %. Poor prognostic factors were increasing age, delayed surgery, poor reduction, and posterior column, transverse posterior wall and T-shaped fracture patterns.

Acetabular surgery poses a major challenge to the trauma surgeon. Complications in the immediate, mid and long term are not rare. Our results compare to other series with shorter follow-up. We believe that the gold standard treatment for displaced acetabular fractures must be open reduction internal fixation performed by a dedicated pelvic surgeon at the earliest time possible. Moreover whether we are merely postponing the inevitable post-traumatic arthritis is still unknown.

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.
