Comparison of Short-Term Clinical Results and Radiologic Changes Between Two Different Minimally Invasive Decompressive Surgical Methods for Lumbar Canal Stenosis

Aims There is a lack of long-term data for minimally invasive acromioclavicular (AC) joint repair. Furthermore, it is not clear if good early clinical results can be maintained over time. The purpose of this study was to report long-term results of minimally invasive AC joint reconstruction (MINAR) and compare it to corresponding short-term data. Methods We assessed patients with a follow-up of at least five years after minimally invasive flip-button repair for high-grade AC joint dislocation. The clinical outcome was evaluated using the Constant score and a questionnaire. Ultrasound determined the coracoclavicular (CC) distance. Results of the current follow-up were compared to the short-term results of the same cohort. Results A total of 50 patients (three females, 47 males) were successfully followed up for a minimum of five years. The mean follow-up was 7.7 years (63 months to 132 months). The overall Constant score was 94.4 points (54 to 100) versus 97.7 points (83 to 100) for the contralateral side showing a significant difference for the operated shoulder (p = 0.013) The mean difference in the CC distance between the operated and the contralateral shoulder was 3.7 mm (0.2 to 7.8; p = 0.010). In total, 16% (n = 8) of patients showed recurrent instability. All these cases were performed within the first 16 months after introduction of this technique. A total of 84% (n = 42) of the patients were able to return to their previous occupations and sport activities. Comparison of short-term and long-term results revealed no significant difference for the Constant Score (p = 0.348) and the CC distance (p = 0.974). Conclusion The clinical outcome of MINAR is good to excellent after long-term follow-up and no significant differences were found compared to short-term results. We therefore suggest this is a reliable technique for surgical treatment of high-grade AC joint dislocation. Cite this article: Bone Joint J 2020;102-B(7):918–924.

Background and Objectives: Lumbar canal stenosis is a common source of chronic low back and leg pain. Minimally Invasive Lumbar Decompression (mild®) is a new minimally invasive treatment for pain relief from symptomatic central lumbar canal stenosis. The procedure involves limited percutaneous laminotomy and thinning of the ligamentum flavum in order to increase the critical diameter of the stenosed spinal canal. The objective of this technical report is to evaluate the acute safety of the mild procedure. Methods: Manual and electronic chart survey was conducted by 14 treating physicians located in 9 U.S. states on 90 consecutive patients who underwent the mild procedure. Patients within local geographical practice areas were selected in keeping with product Instructions For Use. Those patients requiring lumbar decompression via tissue resection at the perilaminar space, within the interlaminar space and at the ventral aspect of the lamina were treated. Data collected included any complications and/or adverse events occurring during or immediately following the procedure prior to discharge. Results: Of 90 procedures reviewed, there were no major adverse events or complications related to the devices or procedure. No incidents of dural puncture or tear, blood transfusion, nerve injury, epidural bleeding, or hematoma were observed. Limitations: Data were not specifically collected; however, regardless of difficulty, in this series none of the procedures were aborted and none resulted in adverse events. Efficacy parameters were not collected in this safety survey. Conclusions: This review demonstrates the acute safety of the mild procedure with no report of significant or unusual patient complications. To establish complication frequency and longer-term safety profile associated with the treatment, additional studies are currently being conducted. Survey data on file at Vertos Medical, Inc.
