NCT05356637

Brief Summary

The overall objectives and purpose of this study is to show that the Smith and Nephew Werewolf Fastseal 6.0 Bipolar Sealer is an effective tool to aide the surgical team in providing significant hemostasis during anterior total hip arthroplasty which would subsequently improve patient outcomes.

Outcome Measures

Primary Outcomes (2)

  • post-operative hemoglobin

    obtained from point of care testing (hemocue hgb 801 device) in clinic (g/dL)

    taken at 48-72 hours post op

  • intra-operative total blood loss

    total blood loss approximated in milliliters from measuring output in suction canister and input from fluid bags with measurement markings

    taken at time of surgery

Secondary Outcomes (7)

  • Post-operative need for transfusion

    6 weeks post operative period

  • Mean operative time ("skin to skin")

    intra-operative

  • incidence of VTE

    for post-operative 6 weeks

  • patient reported pain scoring

    measured at preop, 2 weeks, 6 weeks

  • patient reported pain prescription drug usage

    measured at post-operative period of 6 weeks

  • +2 more secondary outcomes

Eligibility Criteria

Age21 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • The patient is to undergo a standard of care primary total hip replacement for degenerative joint disease. All devices are to be used according to the approved indications, this includes the FDA approved Werewolf Fastseal Bipolar Device.
  • The patient is expected to have an outpatient status and will be discharged \<23 hours.
  • Individuals who are able to speak, read, and comprehend the Institutional Review Board approved Informed Consent Document and willing and able to provide informed patient consent for participation in the study.
  • Individuals who are willing and able to complete follow-up visits and questionnaires as specified by the study protocol.
  • Individuals who are not bedridden per the discretion of the investigator (The intent of "not bedridden" means a permanent situation, not a temporary situation as in a hip fracture or trauma case).
  • Individuals who are a minimum age of 21 years and less than 80 years at the time of consent.

You may not qualify if:

  • Active local or systemic infection.
  • Hematologic disease either inherited or acquired, that would predispose the patient to anemia or increased intra-operative blood loss
  • Currently taking anti-coagulation medications more than 81 mg aspirin every day.
  • Platelet disorder either inherited or acquired with a serum platelet level \<150,000 platelets per microliter.
  • Coagulopathy as seen with routine lab work
  • Unstable/uncontrolled cardiovascular disease such as congestive heart failure, hypertension, or renal disease such as GFR \<70, in the opinion of the investigative team and PI.
  • Excessive alcohol intake or tobacco use, in the opinion of the investigator.
  • Uncontrolled diabetes mellitus with hemoglobin a1c \>7.5%.
  • Established history of previous venous thrombotic events (VTE).
  • Loss of musculature, neuromuscular compromise or vascular deficiency in the affected limb rendering the procedure unjustified.
  • The subject is a woman who is pregnant or lactating.
  • Subject had a contralateral amputation.
  • Previous partial hip replacement in affected hip.
  • Subject has participated in a clinical investigation with an investigational product (drug or device) in the last three months.
  • Contralateral hip was replaced less than 3 months prior to surgery date, contralateral hip is already enrolled in the study, or simultaneous or staged hip replacement is planned
  • +3 more criteria
