Study of SyntheCelTM Dura Replacement to Other Dura Replacements

This study has been completed.
Information provided by (Responsible Party):
Synthes USA HQ, Inc. Identifier:
First received: March 6, 2009
Last updated: March 6, 2012
Last verified: March 2012
Primary Objective: To demonstrate that the SyntheCelTM Dura Replacement performs similarly to or is substantially equivalent to other dura replacements for the repair of the cranial dura in patients undergoing surgical repair of the cranial dura.

Condition Intervention
Cranial Dura Repair
Device: SyntheCel
Device: Other FDA cleared dura replacements

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Participant)
Primary Purpose: Treatment
Official Title: A Prospective, Multi-Center, Randomized, Controlled Clinical Study Comparing SyntheCelTM Dura Replacement to Other Dura Replacements in Patients Requiring Dura Repair Following Cranial Surgery

Further study details as provided by Synthes USA HQ, Inc.:

Primary Outcome Measures:
  • Absence of Cerebrospinal Fluid (CSF) Fistula and Pseudomeningocele [ Time Frame: 6 months ]
    The primary endpoint for measuring effectiveness is such that an individual patient's treatment success requires the absence of CSF fistula (drainage from wound or sinus) and pseudomeningocele within 6 months post-operatively confirmed by radiographic evaluation and physical examination of the surgical site.

Secondary Outcome Measures:
  • Modified Rankin Scale (Patient Function Assessment) [ Time Frame: up to 6 months ]
  • Assessment of Changes in Body Systems (e.g., Head, Neurovascular, Etc.) [ Time Frame: up to 6 months ]
  • Wound Healing Assessment [ Time Frame: up to 6 months ]
  • Device Handling Characteristics (i.e., Ease of Use, Strength, Suturability, Seal Quality) [ Time Frame: up to 6 months ]
  • Radiographic Evaluation [ Time Frame: 6 months ]

    Radiographic evaluation (to determine the presence or absence of the following at the 6 month follow-up visit)

    • Adhesion formation
    • Membrane formation
    • Abnormal thickening along graft (device implant) site
    • Brain edema adjacent to graft (device implant) site

Enrollment: 99
Study Start Date: February 2006
Study Completion Date: January 2009
Primary Completion Date: January 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: SyntheCel Device: SyntheCel
Patients will be clinically followed post-surgery until hospital discharge or within ten (10) days of the procedure and at one (1) month, three (3) months and six (6) months. The data up to and including the 6 month follow-up visit will be used in demonstrating the performance of SyntheCelTM Dura Replacement.
