Initial Wound Care of Open Tibia Fractures

- Soft Tissue Coverage Following Tibial Frx: (Tibia Frx)
    - STSG;
          - split thickness skin grafts require a tissue bed such as periosteum that is capable of granulating;
          - skin graft will not take exposed bone stripped of its periosteum;
    - mechanical closure techniques:
          - references:
                 - The shoelace technique for wound closure in open fractures: report of early experience.
                 - The "rubber band technique": a simple method for closing large skin defects. 
                 - A simple solution for wound coverage by skin stretching
    - multiple relaxing incisions:
          - technique involves creation of multiple 5-10 mm incisions (made w/ 15 blade scapel) thru the dermis made in 1 cm wide rows parallel to
                 wound (w/ the initial MRI made 1 cm from the wound);
                 - the number of rows of relaxing incisions depends on the tightness of soft tissue;
                 - w/ in 3 weeks the relaxing incisions heal by contraction;
          - this technique was demonstrated to be effective in 22 patients w/ lower extremity orthopaedic trauma (there were no skin sloughs or wound infections);
          - technique can also be used to close fasciotomy incisions;
          - relative contra-indication: degloving injuries and possible tranverse wounds;

    - local muscle flaps;
         - wounds located over the proximal third of tibia can usually be covered with local muscle flaps;
         - gastrocnemius Flap
                 - anterior and medial surfaces of tibia usually can be covered w/ medial head of the gastrocnemius muscle;
                 - lateral defects are best covered with a lateral gastrocnemius muscle.
         - soleus flap:
                 - reserved for defects in the middle third of leg; 
                 - Use of the soleus muscle flap to cover part of the distal tibia.

                 - The Gradual Expansion Muscle (GEM) Flap 

         - in the report by Ögün TC, et al., the authors report on a distally based superficial sural artery flap, first described as a distally based
                 neuroskin flap by Masquelet et al., is a skin island flap supplied by the vascular axis of the sural nerve;
                 - it has the largest arc of rotation of all flaps that have been described in this region;
                 - most important advantage is that it does not compromise a major artery;
                 - it is simple to dissect and has a low donor morbidity;
                 - new indication for patients with neglected ruptures of Achilles tendon;
                 - in 13 patients, the flap was successfully transferred;
                 - in two cases, partial necrosis of the flap ensued, which healed with secondary intention;
                 - references:
                          - An Easy and Versatile Method of Coverage for Distal Tibial Soft Tissue Defects.  
                          - Skin island flaps supplied by the vascular axis of the sensitive superficial nerves: anatomic study and clinical experience in the leg.
    - free tissue transfer:
         - used for massive defects that cannot be covered by local muscle in middle and proximal thirds of leg or enlarged defects in distal third of leg;
         - in the report by Pollak AN, et al. (2000), 190 patients (195 limbs) required flap coverage and had six months of follow-up;
               - authors found that use of a free flap to treat limbs with a severe underlying osseous injury was significantly less likely to lead to
                         a wound complication requiring operative intervention than was use of a rotational flap.  
         - common choices:
               - epigastric and rectus abdominis flap:
               - latissimus dorsi
               - gracilis
               - dorsalis pedis fasciocutaneous flap
         - early coverage of soft-tissue deficits of the extremity is indicated in order to minimize infection risk, promote vascularization of underlying
                    bone, and prevent dessication of exposed tissues; 
          - ref: Short-term wound complications after application of flaps for coverage of traumatic soft-tissue defects about the tibia.
    - prognosis: (following free flap coverage);
         - long term free flap survival can be expected in about 85% of patients;
         - ultimate result depends on obtaining frx union and a non-draining wound; 
         - about 20% will end up undergoin BKA;
         - when infection deep infection is present, drainage may persist for over 1 year;
