The purpose of this study is to compare the use of INSORB absorbable staples with metal staples on surgical incision healing after total hip replacement. The study evaluates wound healing, complications, and patient satisfaction regarding wound comfort and appearance after surgery.

Arms Assigned Interventions
Experimental: Insorb staples
Subcuticular Absorbable staples
Device: Insorb staples
absorbable staples required for wound closure
Other Names:
  • Insorb absorbable stapler
  • GDW
Active Comparator: Control
Metal staple wound closure
Device: metal staples (Ethicon metal stapler)
wound closure with metal staples
Other Name: Ethicon metal stapler

Detailed Description:
Subcuticular closure of wounds can provide superior results to percutaneous suture closure due to the elimination of suture or staple tracts. These tracts can lead to infection and migration of epithelial cells adding to scarring, and cross-hatching scars which remain after healing. Absorbable staples can provide a rapid, secure, subcuticular closure of skin as an alternative to the traditional, manual staple or suture closure. This study will compare INSORB absorbable staples to externally applied standard metal staples with respect to effectiveness of incision closure, acute healing, subject comfort level, security and appearance after total hip replacement.
