Abstract
|
|
|
Tendon sheath is an important structure in nutrition, healing and gliding motion of the tendon. To know the effect of tendon sheath restoration with fasica and vein graft after tendon surgery, experimental surgery was done in chickens. Middle toe profundus tendon was severed and repaired.
After tendon repair, sheath was treated in three ways. In group A, tendon sheath of 1cm length was simply excised. Then, sheath was excised and restored with femoral rectus muscle fascia in group B and vein conduit graft in group C.
After casting in flexion for 14 days, the operated foot and digits were taken through a full passive range of motion every 3 days. At the 30th postoperative day, all immobilization was removed and free active range of motion began. Active flexion was measured after death by continuous traction on the proximal produndus tendon(simulated active flexion). The non-operated contralateral foot served as the control.
All operated middle toes achieved significant greater functional return when the sheath was restored either with fascia patch or vein conduit graft in comparison with simple excision of the sheath.
The histologic examination showed that area of healing was better organized with less adhesion when the sheath defect was grafted. The results indicated the possibility of utilizing fascia patch or vein conduit during primary tendon repairs as well as the efficacy of sheath closure.
