Reliability and validity of the Four Square Step Test in patients with hip osteoarthritis before and after total hip replacement

Abstract Background: The aim of the study was to conduct a long-term evaluation of whether total hip replacement permanently affects the quality of postural reactions and body balance. Material and methods: The unilateral Total Hip Replacement (THR) group consisted of 30 subjects (mean age: 69.4). The control group consisted of 30 healthy subjects (mean age: 68.8). The force platform and functional tests such as Timed Up and Go, 3m walk test, Functional Reach Test, 30s Chair Stand Test, Step Test and Berg Balance Scale were used to assess dynamic balance. Results: Subjects from the study group exhibited significantly increased time (p=0.002) and distance (p=0.012) in the tests performed on the force platform compared to the control group. We also observed worse balance and functional test scores in the THR group: Timed Up and Go test (p<0.001), 3m walk test (p<0.001), Functional Reach Test (p=0.003), 30s Chair Stand Test (p=0.002) and Step Test (operated leg: p<0.001, non-operated leg: p=0.002). The results obtained in the Berg Balance Scale tests were not significantly different between the groups (p=0.597). Conclusions: Our research shows that total hip replacement permanently impairs patients’ dynamic balance and functionality in certain lower-extremity activities.

Purpose: The purpose of the study was to describe changes in the kinematic parameters in the patients’ gait after total hip replacement. Methods: Research group of men in the end stage of osteoarthritis indicated to the THR (n = 10; age 54.1 ± 7.5 years; weight 92.2 ± 9.6 kg; height 179.7 ± 5.9 cm). All participants underwent a total of three measurements: before surgery, 3 and 6 months after the surgery. Using the 3D kinematic analysis system, the patients’ gait was recorded during each measurement session and kinematic analysis was carried out. The parameters that were monitored included the sagittal range of motion while walking in the ankle, the knee and the hip joints of the operated and the unoperated limb, and the range in the hip joint’s frontal plane, the rotation of pelvis in the frontal and transverse planes, as well as the speed of walking and the walking step length. Results: Significant increases were found in sagittal range of motion in the operated hip joint, sagittal range of motion in the ankle joint on the unoperated side and in the walking step length of the unoperated limb. Conclusions: During walking after a THR, the sagittal range of motion in the ankle of the unoperated limb increases. Also, the range of motion in the sagittal plane on the operated joint increases, which is related to the lengthening of the step of the unoperated lower limb.

<p class="abstract">Femoroacetabular impingement (FAI) is one of the causes of hip arthritis. If FAI diagnosed earlier and treated properly, arthritis of hip and eventual total hip replacement (THR) can be potentially avoided. We report 48 yr male who presented with left hip severe pain, limp, restricted movements and unable do daily day activities. He is diagnosed to have pincer type of lesion in the acetabular rim and we did arthroscopic excision of the protruding fragment. The patient now has a pain free joint and able to squat and sit cross leg. His pre-operative oxford hip score was 30 which improved to 54. </p>

IntroductionInfection is a major complication following joint replacement (JR) surgery. However, little data exist on baseline use of antibiotics following primary JR and how use changes with subsequent revision surgery. Objectives & ApproachOur study objectives were to describe community use of antibiotics before and after primary total hip replacement (THR) and change in use pre and post revision procedure. Registry data were linked with national medication dispensing data using probabilistic record linkage. Patients with THR for osteoarthritis in a private hospital between 1999 and 2017 were included. Three groups were analysed: patients with primary procedures revised for infection, revised for non-infection reasons and those not revised. Rate of antibiotic dispensing/month was calculated as number of patients dispensed at least one antibiotic in a given month divided by number of patients at-risk. ResultsThere were 102,577 patients included in the non-revised group, 3,156 revised for non-infection and 520 revised for infection. Prior to primary THR, baseline antibiotic dispensing rate was 9-11%/month in all groups. Post-primary rates were similar (10-11%) for non-revised and revised non-infection patients but higher (16-17%) for revised-infection patients. In 1, 6 and 12 months preceding revision for infection, antibiotic use was 55%, 27% and 22%, respectively. For patients revised for non-infection, antibiotic use was 21%, 14%, 13%, respectively. One-month following revision for infection, 82% of patients were dispensed antibiotics, remaining high (38%) at 6-months and 28% at 12-months. In the revision non-infection group, antibiotic use was 48% first month post-surgery, reducing rapidly to 15% at 6-months. Conclusion / ImplicationsNon-revision and revision non-infection patients had similar antibiotic dispensing before and after surgery. Revision infection patients however, maintained higher antibiotic dispensing post-primary, pre and post revision. This may reflect either ongoing infection, need for long-term suppressive therapy or reluctance of treating physicians to terminate treatment.
