Balance and functional disorders in geriatric patients after total hip prosthesis removal.

BACKGROUND

One of the most difficult complications of total hip arthroplasty is an infection in the area of the implant with an incidence of 0.5% to 2.5% resulting in the most severe situation in prosthesis removal.

OBJECTIVE

The aim of the study was to assess postural stability and functional disorders in patients after hip prosthesis removal.

METHODS

A group of 15 patients after hip prosthesis removal was compared to a control group of 15 healthy persons who were age-matched without any symptoms of degenerative disorders in the lower spine and lower extremities. The static balance test was conducted on a bi-modular stabilometric platform, registering the movement of the centre of foot pressure. The functional state of the patients was assessed on the basis of the Harris Hip Score (HHS).

RESULTS

Patients had poor functional result (HSS mean 62.29 ± 12.92 points). Obtained results of postural stability of patients showed huge difficulties maintaining stability and showed statistically significant differences in a majority of the analysed parameters.

CONCLUSIONS

Several stability parameters showed significantly worse results in patients after hip prosthesis removal. Special attention should be paid and focused physiotherapy should be undertaken for patients with a stability disorder and functional status to prevent falls and improve functioning.
