A consecutive series of 320 patients with an intracapsular fracture of the hip treated with a dynamic locking plate (Targon Femoral Neck (TFN)) were reviewed. All surviving patients were followed for a minimum of two years. During the follow-up period 109 patients died.

There were 112 undisplaced fractures, of which three (2.7%) developed nonunion or re-displacement and five (4.5%) developed avascular necrosis of the femoral head. Revision to an arthroplasty was required for five patients (4.5%). A further six patients (5.4%) had elective removal of the plate and screws.

There were 208 displaced fractures, of which 32 (15.4%) developed nonunion or re-displacement and 23 (11.1%) developed avascular necrosis. A further four patients (1.9%) developed a secondary fracture around the TFN. Revision to a hip replacement was required for 43 patients (20.7%) patients and a further seven (3.3%) had elective removal of the plate and screws.

It is suggested that the stronger distal fixation combined with rotational stability may lead to a reduced incidence of complications related to the healing of the fracture when compared with other contemporary fixation devices but this needs to be confirmed in further studies.

Aim: This study aims to quantify pain relief and quality-of-life benefit from a diagnostic SIJ injection.

Methods: 50 consecutive patients were retrospectively recruited with unilateral low back pain, pain mapping compatible with a sacroiliac origin, tenderness over the SIJ, and no obvious source of pain in the lumbar spine. These were selected for a diagnostic SIJ injection. A structured questionnaire was completed both pre- and post-injection. Median patient age was 63. All patients were injected under fluoroscopic imaging with Triamcinolone 40mgs and 3mls Ropivacaine hydrochloride.

Results: Onset of lower back pain symptoms ranged from 1962 to 2007. 38 patients (76%) had some form of previous non-operative treatment. No patients had previous injection or surgery. 8 patients (16%) were smokers. 17 patients (34%) had a desk based job, 22 patients (44%) had a manual job, 7 patients (14%) had heavy manual jobs. 18 patients (36%) had sustained previous back injury. A visual assessment score was carried out for low back pain and pain in both legs, both pre- and post-injection. Overall, 16 patients (32%) reported no change in their symptoms, 7 (14%) reported worsening, but in 27 (54%) improvement was recorded. When considering the Oswestry Disability Index score, 18% reported no symptom change, 24% worsened and 58% improved.

Conclusion: History and physical examination can enter SIJ syndrome into the differential diagnosis, but cannot make a definitive diagnosis. Fluoroscopically guided diagnostic SIJ injection is the gold standard test for making the diagnosis whilst also conferring substantial pain relieve and quality-of-life benefit.

Aim: This study was a sub group analysis of a larger study. The aim was to quantify pain relief and quality-of-life benefit from a single diagnostic SIJ (Sacro-Iliac joint) injection.

Methods: Between August 2008 and February 2009, 56 consecutive patients were retrospectively recruited with unilateral low back pain, pain mapping compatible with a sacroiliac origin, tenderness over the SIJ, no obvious source of pain in the lumbar spine and no neurological deficit. These were selected for a diagnostic SIJ injection. A structured questionnaire was completed both pre- and post-injection. Median patient age was 63. All patients were injected under fluoroscopic imaging with Triamcinolone 40mgs and 3mls of 0.5% Ropivacaine hydrochloride.

Results: 6 patients were excluded from the study on the basis of incomplete answers. 38 patients (76%) had some form of previous non-operative treatment. No patients had previous injection or surgery. 8 patients (16%) were smokers. 17 patients (34%) had a desk based job, 22 patients (44%) had a manual job, 7 patients (14%) had heavy manual job. 18 patients (36%) had sustained previous back injury including rear ended road traffic accidents. A numerical rating score was carried out for low back pain and pain in the affected and unaffected leg; both pre- and post-injection. In 27 patients (54%) significant improvement was recorded, 16 patients (32%) reported no change in their symptoms, and only 7 (14%) reported worsening. When considering the Oswestry Disability Index score, 58% improved, 18% reported no symptom change, and 24% worsened. The mean pre injection Numerical Rating Score of back pain in patients who had a previous injury to the back was 7.66 and that improved to 5.72 (P = 0.0287).

Discussion: Sacroiliac joint as a potential source of back pain has had less focus following the identification of the disc pathology by Mixter and Barr. The pain from the joint is real and needs to be addressed specifically with injection as a diagnostic measure. Blanket prescription of “low back - core stability exercises” without identification of other potential non red flag causes of back pain should be discouraged. The mechanism of sacroiliac joint syndrome following road traffic accidents occur due to one leg being on the brake pedal stabilizing one half of the pelvis, whilst the opposite hemipelvis twists forward following a rear end collision.

Conclusion: History and physical examination can enter SIJ syndrome into the differential diagnosis, but cannot make a definitive diagnosis. Fluoroscopically guided diagnostic SIJ injection is the gold standard test for making the diagnosis whilst also conferring substantial pain relieve and quality-of-life benefit. This benefit is also seen in back pain following traumatic injuries including rear end motor vehicle collisions.
