Chronic posterolateral elbow instability. Ligament reconstruction.
Abstract
Introduction: The objective of this paper is to evaluate the results of a series of patients with posterolateral elbow instability treated with reconstruction of the ulnar collateral ligament using tendon graft.Methods: We reported 10 patients with a mean age of 47 years. Time from posterolateral dislocation to surgery was 16 months. The pivot shift test under anesthesia was positive in all patients. Seven patients had stage 1 instability according to Horii, one patient presented a stage 2 and two patients had stage 3 under fluorosopy. Palmaris minor was the most common tendon used for reconstruction. Follow-up was 21 months.Results: Flexo-extension was 126-3º. Pain according to visual analogue scale was 0 at rest and 1 in activity. DASH score was 12 and Mayo Clinic score was 95. Sensation of instability was not reported by any patient. The pivot shift test in an awake patient was always negative. Inestabilidad posterolateral crónica de codo.Conclusions: Ulnar collateral ligament reconstruction with tendon graft in patients with posterolateral elbow instability is useful to restore joint stability. Best results were observed in patients with stage 1 or 2 instability according to Horii. Residual instability was not observed.Downloads
