Sacroiliac joint (SIJ) fusion is a controversial yet last resort operative technique to address SIJ pain. The current study aims to determine the patient outcomes of SIJ fusions, in a single surgeon series utilising an anterior approach with 2 DC plates across the joint and iliac crest autograft.

Retrospective case series involving 11 patients who had 13 SIJ fusions performed over an 8 year period (2002–2010). Patients were identified by electronic key word search from databases at Middlemore hospital and the private sector. Dictated clinic letters and operation notes were reviewed to obtain demographic data and outcomes data including complications. Postoperative radiology reports were reviewed to document radiographic fusion status. Telephone interviews were conducted to measure clinical outcome scores via the Majeed Pelvic Score and the 12-item Short-Form Health Survey (SF-12).

10 out of 11 patients (entailing 12 SIJ fusions) responded and participated in the study, equating to over 90% follow up. 2 cases were managed at Middlemore Hospital, with the remainder in the private sector. All cases but one had a ‘post-traumatic arthritis’ etiology. Diagnosis was made by CT guided local/steroid injection into the joint in conjunction with CT/bone scan/MRI imaging. The Majeed score improved markedly for 9 of 12 SIJ fusions (75%). 10 of 12 patients stated they would have the procedure again. 7 of 12 fusions (58%) had postoperative complications including blood loss, haematoma, nerve injury (including one case of permanent foot drop), non-union, infection of the joint/metal ware, hernia and urinary retention. 5 of 12 fusions (42%) experienced altered sensation over the lateral femoral cutaneous nerve distribution. All except one patient eventually had x-rays or CT scans postoperatively that reported radiographic fusion of the joint.

In appropriately selected patients with SI joint arthrosis, 3/4 patients reported significant improvement in function and pain level after SIJ fusion. Chronic pain (from other sources) and major complications were a feature amongst those failing to benefit. Lateral femoral cutaneous nerve palsy has high incidence with the current operative technique.

The timely management of anticoagulated elderly trauma patients remains a contentious issue. Presently, the literature consists of largely contradictory expert opinions without evidence from randomised control trials. This study seeks to audit the practices of a non-metropolitan orthopaedic service, as a prelude to developing a local protocol for optimal management.

All orthopaedic admissions to Toowoomba Hospital from January 2004 to December 2008 were reviewed. Approximately 700 patients over the age of 60 years were admitted with lower limb trauma. Those patients with pre-injury medication with warfarin and clopidogrel were identified, along with chronologically matched untreated patients. Those patients with coexisting head-injures, and those with sub therapeutic INR (INR <1.5) on admission were excluded from the study groups. Groups were analysed with respect to age, Injury Severity Score, ASA, time to theatre, time to discharge, transfusion requirement, and complications. Statistical analysis was completed using the T-test.

Of the 700 patients identified, 24 were treated with warfarin and 28 treated with clopidogrel. Two patients with pre-injury warfarin use were excluded due to sub therapeutic INR on admission (INR 1.0 and 1.3). The control and treatment groups were statistically similar with respect to age, Injury Severity Score, and ASA. Injury patterns were similar across groups with over 80% proximal femoral fractures in each group. In both the warfarin and clopidogrel groups there was a statistically significant increase in time from admission to theatre compared with their matched controls (P<0.001). Average number of days to theatre was seven days and five days for the clopidogrel and warfarin groups respectively, compared to two days for both control groups. There was no significant difference between the groups in length of time from operation to the end of their acute care. There was no increase in transfusion requirement in those patients with pre-injury clopidogrel use. Pre-injury warfarinisation demonstrated a trend toward increased transfusion requirement compared with the matched controls (P=0.052); however, this was not significant. There was no clinically significant increase in complications in those patients with pre-injury use of warfarin or clopidogrel.

This study demonstrated no increased morbidity in elderly patients with lower limb trauma when being treated with anticoagulants prior to injury. However, there is a significant delay in operative intervention in these patients. We believe this presents a case for early reversal of anticoagulant therapy in order to expedite treatment.
