Nicoll evaluated 705 patients with fractures of the tibial shaft. He identified a number of factors determining the quality of the clinical outcome. The author is from Mansfield, England.
Parameters:
(1) stiffness in the ankle (loss of extension or flexion)
(2) stiffness in the tarsus
(3) stiffness in the knee
(4) anterior or posterior bowing
(5) valgus or varus angulation
(6) rotational deformity
(7) shortening of the leg
