Background: Posterolateral synovial fold syndrome is a rare entity on elbow pathology. Careful evaluation of clinical presentation and radiological imaging is essential to obtain the diagnosis. Treatment is usually resection of the synovial fold with arthroscopy. Objective: To retrospectively evaluate and review the functional outcomes, findings and results after arthroscopic surgery in a case series of patients with posterolateral synovial fold syndrome treated with a modified arthroscopic technique. Methods: Between 2010 and 2020, 6 patients diagnosed with posterolateral synovial fold syndrome were treated with average of 12 months follow-up (SD ± 17.3) they were evaluated for clinical symptoms, radiological signs and arthroscopic findings. Patient outcome was assessed pre- and postoperatively by the Mayo Elbow Performance Index (MEPI), which assesses pain, ROM, stability and function. Statistical analysis was performed with the student’s t-test. P=0.05 were considered statistically significant. The study was approved by ethics committee of Hospital Clinica Mompia, Santander, Spain. Results: In all cases the synovial fold was swollen and thickened with some synovitis adjacent to the fold on the radio capitellar joint. Mild chondromalacia was observed on the capitellum and the posterolateral zone of the radial head. No pathology was observed at the anterior compartment of the elbow. All patients showed up a clinical improvement with the disappearance of pain and snapping and returned to physical activities. No loss of motion was observed. No complication or recurrence of the symptoms appeared during the 12month of follow-up. The preoperative MEPI score of 64.1 points (SD ± 5.8) had significant improvement to 92.5 (SD ± 8.2) on postoperative at 12 months of follow up. Conclusion: Management of a symptomatic posterolateral synovial fold is successful and effective with our proposed arthroscopic technique. |
