Static Balance Disorders in Patients After Surgical Treatment of Hip Acetabular Fractures

Completed

• Conditions: Acetabular Fracture; Disability Physical; Hip Fractures; Balance; Distorted
• Interventions: Procedure: postural stability measurements

• Registration Number: NCT04902209
• Lead Sponsor: Józef Piłsudski University of Physical Education

Brief Summary

The mechanism of maintaining balance is a complex phenomenon, involving numerous systems of human body. High-energy trauma resulting in acetabular fracture damages some of the elements composing this delicate mechanism, potentially increasing the risk of falls in patients. There have not been any studies so far on balance levels in patients after surgical treatment of acetabular fractures.

Questions/purposes

1. Do balance disorders occur in patients after ORIF of acetabular fractures?

2. Do surgical approach and fracture pattern influence balance level of patients?

3. Should therapy programs include certain stabilometric parameters adequate especially for this type of injury?

Detailed Description

Methods Between 2014-2017, investigators evaluated 110 subjects: 55 patients after surgical treatment of acetabular fracture - the study population (mean age 43.6 ± 14.8 years) and 55 healthy subjects - the clinical control group (mean age 43.8 ± 14.9 years).

To ensure reliability of results, controls were individually matched to appropriate study population patients, in terms age, sex, body height and mass.

The study was conducted in Public Hospital and the protocol was approved by the Commission of Ethics (SKE 01-21/2014).

Investigators measured static balance in double leg stance (eyes open/eyes closed) for 30s on CQStab2P, a double module stabilometric platform.

The pain component of the Harris Hip score and the quality of fracture reduction (according to Matta's criteria) in digitized anteroposterior and two oblique view radiographs were analyzed.

Primary Outcome Measures

Static balance assessment with eyes open and closed	2014-2017	Static balance parameters were analysed.

Secondary Outcome Measures

Name	Time	Method
Harris hip score	2014-2017	Investigators determined patients' functional state on the basis of Harris Hip Score (HPP). This is an orthopedic tool which assesses functional state of patients after hip interventions. Harris hip score showed high validity and reliability. The tool assesses the following aspects: pain in the operated limb, hip movement range (registered with hand held goniometer), gait (limp, the distance a patient is able to walk, using mobility aids), other activities (walking the stairs, putting on shoes, and sitting, using public transport). Patients scored points for each analyzed element. The maximum number of points was 100. The score reflected the level of patient's functional state (a greater number of points meant that the patient had better ability). Then, we compared the results to the norms.
