Ultrasound imaging has become an essential adjunct to clinical examination when assessing a patient with suspected rotator cuff pathology. With the new high-resolution portable machines it has become feasible for the shoulder surgeon to perform the scans himself in the clinic and save a great deal of time. This study was conducted to examine the accuracy of the ultrasound scans performed by a single surgeon over a period of four years (2001-2004).

The ultrasound findings were uniformly documented and collected prospectively. Out of a total of 364 scanned patients we selected 143 who ultimately received an operation and we compared the surgical findings with the ultrasound reports. The intra-operative findings included 77 full thickness supraspinatus tears, 24 partial thickness tears and 42 normal cuffs. Three full thickness tears were missed on ultrasound and reported as normal/ partially torn. Four normal/ partially torn cuffs were thought to have a full thickness tear. This presents 96.3% sensitivity and 94.3% specificity for full thickness tears. Three partial thickness tears were reported normal on ultrasound and eight normal cuffs were thought to have partial thickness tears. This presents 89% sensitivity and 93.7% specificity for partial thickness tears. The size estimation of full thickness tears was more accurate for large/massive tears (96%) than moderate (82%) and small/pinhole tears (75%). The tear sizes were more often underestimated which may partly reflect disease progression during the unavoidable time lag between scan and surgery.

We conclude that shoulder ultrasound performed by a sufficiently trained orthopaedic surgeon is a safe and reliable practice to identify rotator cuff tears.

Background: To determine whether the operation of LSD destabilizes the lumbar spine and leads to an increase in any pre-existing scoliosis or spondylolisthesis. Lumbar spondylosis, which commonly includes a degenerative listhesis and a scoliosis, is the commonest cause for stenosis in the lumbar spine. The standard operation for spinal stenosis remains a laminectomy with fixation and fusion in the presence of possible instability. The laminectomy, however, destabilises the spine and the instrumented fusion makes it a much bigger operation in patients often not best placed to cope with it. The more limited operation of LSD, which has previously been reported to this society, avoids a simultaneous fusion or instrumentation and has been shown to give long term symptomatic relief (1) Its possible effect on the stability of the spine has not previously been reviewed.

Methods: A retrospective clinical and radiological review of consecutive patients operated on for degenerative spinal canal stenosis with either a pre-existing scoliosis or degenerative listhesis or both. Sixty-one patients (44 female and 17 male) with a mean age at operation of 72.8ys (range: 54–85). Pre-operatively 35patients (57%) had a degenerative listhesis, 14 patients (23%) a lumbar scoliosis and 12 (20%) had both. The mean postoperative follow-up was three years (range from one to fourteen years).

Results: None of the 47 patients with a preoperative degenerative spondylolisthesis had any change in grade of the listhesis. Also no patient developed a new spondylolisthesis.

Of the 26 patients with a preoperative scoliosis, 10 progressed by a mean of 4.9° (range 2°–15°)

Conclusion: The results show that the operation of LSD was not associated with the development of a spondylolisthesis or a further progression of a pre-existing listhesis, and no patient developed a scoliosis. In those who had a scoliosis pre-operatively, 38% progressed and this only to a degree which we believe falls within the natural progression to be expected in such a group of patients. We believe these results support the view that the operation of Limited Segmental Decompression for spinal stenosis does not significantly destabilize the spine, even in a group that would appear most vulnerable, and as such there is no indication in such cases to consider a simultaneous instrumentation and fusion.

Ultrasound has become an essential adjunct to clinical examination when assessing a patient with suspected rotator cuff pathology. This prospective study was conducted to examine the accuracy of the scans performed by a surgeon over a period of four years.

Out of 276 scanned patients we selected 143 who ultimately received an operation and we compared the findings with the ultrasound reports.

The surgical findings included 77 full thickness tears, 24 partial thickness tears and 42 normal cuffs. Two small tears were missed and one partial thickness tear was reported as full thickness. This presents a 98.6% sensitivity and 99.3% specificity for full thickness tears. Three partial thickness tears were reported normal on ultrasound and eight normal cuffs as partial thickness tears. This presents a 97.9% sensitivity and 94.4% specificity for partial thickness tears. The size estimation of full thickness tears was more accurate for large/massive tears (96%) than moderate (82%) and small/pinhole tears (75%). The tear sizes were more often underestimated which may partly reflect disease progression during the unavoidable time lag between scan and surgery.

We conclude that shoulder ultrasound performed by a sufficiently trained orthopaedic surgeon is a safe and reliable practice to identify rotator cuff tears.
