Ankle Tissue Injury Wound clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Lateral Supramalleolar Perforator Flap Reconstruction Through Branches Outside of the Ankle Tissue Defects

Start date: January 1, 2007
Phase:
Study type: Observational

The lateral ankle is a common site of tissue defects and the defects in this area are often accompanied by exposure of the fibula and tendons. Microsurgical tissue transfer or a pedicled flap is needed to cover those exposures for even a relatively small defect due to the insufficiency of the local cutaneous and muscle flap in this area. Koshima et al. and Wei et al. began to propose the concept of localized perforator flaps, which were initially applied to free perforator flaps. The main benefits of such localized perforator flaps are described below. 1. It preserves vital blood vessels and the underlying muscles and fascia. 2. Complications in the donor area are rare and can be direct or partial sutures. 3. Not technically demanding, although we need to find the vessel but not the vessel junction. 4. Shorter surgery time. There are many choices of perforator flaps for lateral ankle soft tissue defects, including lateral upper ankle flap, retrograde anterior tibial artery flap, retrograde gastrocnemius flap, etc. Among them, the lateral upper ankle flap is one of the flaps commonly used for reconstruction of lateral ankle tissue defects, and the research on the lateral upper peroneal artery perforator flap is limited.
