As discussed on Radio 2, Jeremy Vine show, Wednesday last week.
Researchers show that one of the most common surgical procedures in the Western world is probably unnecessary. Keyhole surgeries of the shoulder are useless for patients with ‘shoulder impingement’, the most common diagnosis in patients with shoulder pain.
The Finnish Shoulder Impingement Arthroscopy Controlled Trial (FIMPACT) compared surgical treatment of shoulder impingement syndrome to placebo surgery. Two years after the procedure the study participants, both those in the group who underwent surgery and the ones in the placebo group, had equally little shoulder pain and were equally satisfied with the overall situation of their shoulder.
“These results show that this type of surgery is not an effective form of treatment for this most common shoulder complaint. With results as crystal clear as this, we expect that this will lead to major changes in contemporary treatment practices,” said the study’s principal investigators chief surgeon Mika Paavola and professor Teppo Järvinen from the Helsinki University Hospital and University of Helsinki.
This research confirms previous randomised studies showing that keyhole decompression surgery of the shoulder does not alleviate the symptoms of patients any better than physiotherapy.
The FIMPACT study involved 189 patients suffering from persistent shoulder pain for at least three months despite receiving conservative treatment, physiotherapy and steroid injections. Patients were randomised to receive one of three different treatment options, subacromial decompression surgery, placebo surgery (diagnostic arthroscopy, which involved arthroscopic examination of the shoulder joint but no therapeutic procedures) or supervised exercise.
Two years after the start of the study, patients were asked about shoulder pain and other symptoms they had experienced, as well as their satisfaction with the treatment and its results. The patients in the decompression or placebo groups were also asked which group they believed they had been in — actual surgery or placebo.
Overall, shoulder pain was substantially improved in all three groups from the start of the trial. However, decompression surgery offered no greater benefit to shoulder pain than placebo surgery.
The group that received exercise therapy also improved over time.
“Based on these results, we should question the current line of treatment according to which patients with shoulder pain attributed to shoulder impingement are treated with decompression surgery, as it seems clear that instead of surgery, the treatment of such patients should hinge on nonoperative means,”
Järvinen states. “By ceasing the procedures which have proven ineffective, we would avoid performing hundreds of thousands useless surgeries every year in the world,”
Järvinen points out. “Fortunately, there seems to be light at the end of the tunnel as the NHS in England just released a statement that they will start restricting funding for ‘unnecessary procedures’ and the list includes subacromial decompression. We applaud this initiative and encourage other countries to follow this lead.”
“We have to spend taxpayers’ money responsibly. If we are spending money on procedures that are not effective, that money is deprived from treatments that are clinically effective and would provide benefits to patients. One component in becoming more efficient is to make sure we are not undertaking unnecessary procedures,” Dr. Taimela concludes.
The FIMPACT research project includes the Helsinki and Tampere University Hospitals in Finland.
