ShoulderFewer anchors achieves successful arthroscopic shoulder stabilization surgery: 114 patients with 4 years of follow-up
Section snippets
Materials and methods
The study comprised 114 consecutive patients. Inclusion criteria were all patients with anterior instability and a Bankart lesion undergoing arthroscopic stabilization. Patients with bony glenoid defects >20% were excluded from the study and treated with a Latarjet procedure. All patients were followed up for a minimum of 4 years postoperatively. The Oxford Instability Score (OIS) was collected prospectively. All other data were collected retrospectively by use of patient case notes, x-ray
Results
Our series comprised 114 patients, of whom 99 (86.8%) were male and 15 (13.2%) female. The mean age was 31 years (age range, 15-71 years). In total, 10 patients were older than 50 years. There were 87 (76.3%) Hill-Sachs lesions, 15 (13.2%) bony Bankart lesions, 15 (13.2%) glenoid defects, and 11 (9.6%) SLAP lesions. The number of anchors used is shown in Figure 4. This demonstrates that the majority of patients, 71 patients (62.3%), received only 1 anchor; 40 patients (35.1%) received 2
Discussion
In our series, we have used only 1 anchor in the majority of patients. Although most surgeons commonly use 3 anchors, we have used 3 anchors only in 3 (2.6%) of our patients. Despite our smaller number of anchors, our failure rate of 6.1% compares favorably with that of other published series.1, 2, 3, 4, 5, 6, 8, 10, 11, 13, 15, 16, 17, 18, 19, 20, 21, 22, 23 Table II shows how our results compare with the literature.
Strengths of our study include a relatively large patient sample size, a
Conclusion
Although most surgeons choose to use 3 anchors as their standard practice, we found that fewer anchors can achieve successful shoulder stabilization. A single anchor was sufficient for the majority of our patients. We found no statistically significant difference in outcome for patients treated with a single anchor compared with those treated with 2 or 3 anchors. In fact, our experience shows that even in patients with minor bony Bankart lesions and minor glenoid defects, a single anchor can be
