X-ray and Cineradiographical Evaluation of the TSB prosthesis

- a Comparison with the PTB BK prosthesis

Total surface-bearing (TSB) below-knee prosthesis with an Icelandic roll-on silicone socket (ICEROSS) has recently become popular in prosthetics. This new below-knee prosthesis does not require the knee cuff that is used as a suspension device in the convcnti6nal PTB prosthesis. Due to the great amount of friction between the silicone socket and skin in the TSB prosthesis, there is a reduction in the piston motion when the heel is on the ground and an increase in the flexion angle of the knee in the swinging phase. The feeling of stability and of secure attachment are also superior in the TSB prosthesis.

X-ray and cineradiography measurements were used to compare the suspension effect and stability of a TSB below-knee prosthesis with an ICEROSS system to that of a PTB below-knee prosthesis. The suspension effect was measured by translating the distance between the tibia and the socket in both suspension position and weight-bearing position in both type of prostheses. The suspension effect of the TSB prosthesis (2.53 ± 0.90cm) was superior to that of the PTB prosthesis (3.60 ± 0.56cm) (p < 0.05) by x-ray measurement. The suspension effect of the TSB prosthesis (0.1, 0.4, 0.72cm) was superior to that of the PTB prosthesis (0.3, 0.48, 1.03cm) (p<0.01, p<0.05) by cineradiographic measurement. The stability was measured as the angle between the axis of tibia and prosthesis at the time of the heel contact and the toe off. The angle change of the TSB prosthesis was smaller than that of the PTB prosthesis statistically.

PARTIAL-FOOT AMPUTATIONS IN JAPAN Noriko Maruno, Masahiro Mikami (Dept. of Rehabilitation Medicine, Teikyo University, Tokyo, Japan)

 

Japanese lifestyle has "westernized" and most Japanese wear shoes when going outdoor. But at home, most Japanese stay barefoot. Partial-foot (PF) amputees have the benefit of walking without prostheses. We examined whether PF amputtees have adjusted to Japanese lifestyle after operation.

Nine patients, excluding toe amputations, were referred to our department, and 6 had prosthetic training. All were male and indications for amputation were: trauma (3), tumor (2) and DM (1) . Age at amputation was 23 to 50 years. Boyd amputation had been performed in four patients. In two patients, amputation was at the Chopart level, and in one, at the Lisflanc level. Leg length discrepancies in Boyd amputees were from 2 to 5 cm.

All patients wore prosthesis outdoors. At home, 3 amputees wore no prosthesis, they were Chopart (1), Lisflanc (1), and Boyd (1). Three Boyd amputees wore prosthesis because of leg length discrepancies.
