  • Title: Long-term outcome of anterior decompression and spinal fixation after placement of the Wellesley Wedge for thoracic and lumbar spinal metastasis.
    Author: Yen D, Kuriachan V, Yach J, Howard A.
    Journal: J Neurosurg; 2002 Jan; 96(1 Suppl):6-9. PubMed ID: 11795715.
    Abstract:
    OBJECT: The authors assessed the long-term results of anterior decompressive and vertebral body reconstructive surgery in which the Wellesley Wedge was applied in patients with metastatic spinal lesions over the life span of these individuals. METHODS: The authors performed a retrospective review of the outcome of 27 consecutively treated patients who underwent surgery for thoracic or lumbar spine metastases. Decompressive surgery was performed via an anterior thoracotomy and/or retroperitoneal approach depending on the level of the lesion. The spine was reconstructed using a U-shaped plate with an interposed methylmethacrylate strut known as the Wellesley Wedge. RESULTS: Thirty percent of patients suffered medical complications whereas 22% experienced postoperative improvement, as reflected by an improved Frankel grade. Used in patients with a variety of primary tumor types, a spectrum of ages and neurological status, and extensive preoperative osseous spinal involvement and deformity, the Wellesley Wedge resulted in spinal stability for the duration of patients' lives in 92%. CONCLUSIONS: In this series the patient selection process for surgery was a challenge yet to be solved; however, considering the durability of the Wellesley Wedge itself, the authors will continue to use it in selected patients.
