Sutures Versus Staples for Wound Closure in Orthopaedic Surgery
Study Details
Study Description
Brief Summary
The trial is a randomized, controlled trial. Adult patients undergoing orthopaedic surgical procedures would be randomized to one of two groups for surgical wound closure, skin sutures or skin staples. The primary outcome measures would be surgical site infection indicated by the use of oral or intravenous antibiotics for suspected wound infection and/or re-operation at the same site. Patients would be followed up as per their usual post-operative course for a total of three months in the trauma and spine population and six months in the total joint arthroplasty population. It is hypothesized that wounds closed with sutures and staples will have similar infection rates as defined by the use of antibiotics or reoperation.

Detailed Description
To date, there is no clear consensus on the method that is best for closure of surgical wounds in orthopaedic surgery. Orthopaedic surgeons have a multitude of wound closure habits. A recent meta-analysis comparing staples to sutures in wound closure demonstrated a three-fold increase in infection in stapled wounds compared to sutured wounds. The studies used in the meta-analysis were primarily of poor methodological quality.
A large, well-designed randomized, controlled trial is needed to guide orthopedic surgeons in their choice of wound closure materials. This study would attempt to provide information on the use of sutures versus skin staples and the effect on the development of surgical site infections in adults undergoing orthopaedic procedures.
A parallel group randomized controlled trial with institutional review board approval will be conducted. Patients will be randomized intraoperatively to have skin wounds closed with sutures or staples. Dressings will be used to maintain blinding of participants and outcome assessors. The primary outcome measure will be infections adjudicated by a blinded data safety monitoring committee. Suspected infections will be defined by: Use of antibiotics or reoperation for infection at the operative site within three months (six months for arthroplasty subgroup) The independent review, board blinded to treatment assignment, will adjudicate suspected infections based on clinical data. A cost analysis will also be performed to compare the costs associated with wounds closed with sutures and staples from a health care institution perspective.
All data will be analyzed by a blinded epidemiologist. Dichotomous primary and secondary outcome measures will be analyzed using the Chi-squared statistic. Continuous outcome measures will be analyzed using Student's t-test. Subgroup analysis will compare infection rates using sutures versus staples in each anatomic area (upper extremity, pelvis/acetabulum, hip/femur, knee, ankle). A further subgroup analysis will be conducted comparing trauma patients to elective patients. Non-infected revision surgery will also be compared to primary surgery.
It is hypothesized that wounds closed with sutures and staples will have similar infection rates as defined by the use of antibiotics or reoperation.

Outcome Measures
Primary Outcome Measures
- Surgical site infection [6 months]
Suspected cases will be identified by one or all of the following: use of intravenous antibiotics, use of oral antibiotics (patient self-reported), re-operation at same site. A blinded committee will adjudicate each suspected case and determine true infections using available clinical information. Agreement will be determined by vote.
Secondary Outcome Measures
- Additional healthcare contact related to their surgery [6 months]
As defined by self-reported visits to other healthcare professionals.
- Dressing changes by homecare/patient at home [6 months]
Defined by homecare consult records and patient self-report
- Length of stay [6 months]
Based on admission and discharge dates
- Wound drainage [6 months]
As defined by necessity for dressing changes after 72 hours for fluid leakage
- Wound necrosis [6 months]
Evidence of marginal skin death at the surgical site as evidenced by skin slough, blackening or liquefaction
- Patient satisfaction with wound appearance [6 months]
Using visual analogue scale
- Visual analogue pain score for suture/staple removal [2 weeks post-operative]
Patients will rate the pain experienced in removing the wound closure materials in clinic prior to unblinding.
