# Influence of Spinal Deformity on THA

**Official Title:** Influence of Spinal Deformity on Acetabular Cup Position in THA.

**NCT ID:** [NCT05892523](https://clinicaltrials.gov/study/NCT05892523)

## Key Facts

- **Status:** UNKNOWN
- **Study Type:** OBSERVATIONAL
- **Target Enrollment:** 80
- **Lead Sponsor:** Assiut University
- **Conditions:** THA
- **Start Date:** 2023-11-08
- **Completion Date:** 2025-01-01
- **CT.gov Last Update:** 2023-07-27

## Brief Summary

The aim of the study is to understand the effect of spinal deformity and altered sagittal plane parameters of lumbosacral complex on acetabular cup position in THA.

## Detailed Description

Investigators will Find out if there is change in the acetabular cup including the abduction and anteversion angles in patients who had THA and has spinal deformity

## Eligibility

- **Minimum age:** 30 Years
- **Maximum age:** 70 Years
- **Sex:** ALL

```
Inclusion Criteria:

* all patients who had primary THA in 6 month duration
* patients from 30 to 70 years old with primary THA

Exclusion Criteria:

* patients who have ankylosing spondylitis
* patients with revised THA
* patients with associated injuries in lower limb
```

## Interventions

- **THA** (PROCEDURE) — positioning the acetabular cup regarding abduction and anteversion angles with or without concern to spinal deformity

## Primary Outcomes

- **change of acetabular cup position in spinal deformity** _(time frame: immediate post operative X-ray hip anteroposterior and cross table lateral views in supine position measuring cup abduction and anteversion angles and 3 month post operative X-ray hip and lumbosacral anteroposterior and lateral views in standing position)_ — change of acetabular cup abduction and anteversion angles in patients who has THA and spinal deformity

## Secondary Outcomes

- **complications of THA mainly hip dislocation and HOOS hip survey** _(time frame: 3 month duration post operatively)_
