TABLE 1.

Summary of the five original surgical treatments, results on EDL tendon length, and final statistical groups.

Surgical Group Surgical Treatment Steps Tendon Length Effect Statistical Group
Sham (n = 8)

  1. Tendons exposed, freed from surrounding structures

 Control Length Control Tendon Length (n = 16)
Unchanged (n = 8)

  1. Tendons exposed, freed from surrounding structures

  2. Tendons transected

  3. Tendons repaired at preoperative length

 Control Length
Tenotomy (n = 8)

  1. Tendons exposed, freed from surrounding structures

  2. Tendons transected

  3. Tendons not repaired

 Increased Length Increased Tendon Length (n = 16)
Tendon-Added (n = 8)

  1. Tendons exposed, freed from surrounding structures

  2. Tendons transected

  3. Autograft inserted: 2 mm proximally, 6 mm distally

 Increased Length
Tendon-Removed (n = 8)

  1. Tendons exposed, freed from surrounding structures

  2. Tendons transected

  3. Tendon segments removed: 2 mm proximally, 6 mm distally

 Decreased Length Decreased Tendon Length (n = 8)

Surgical Groups were combined to form Statistical Groups based on similar effects on tendon length. The Sham and Unchanged surgical groups were combined to form the Control Tendon Length group. The Tenotomy and Tendon-Added groups were combined to form the Increased Tendon Length group. The Tendon-Removed group became the Decreased Tendon Length group.
