Dataset

Motivation

To develop and evaluate a multimodal machine learning pipeline that predicts 5-year dislocation risk after primary THA using preoperative AP radiographs and clinical data, improving upon a prior clinical-only calculator.

Sampling

Retrospective cohort from Mayo Clinic total joint arthroplasty registry, surgeries 1998–2018; excluded patients without digitized preoperative AP pelvic/hip radiographs.

Partitioning scheme

10% holdout test set (n=1718 patients) with remaining data used for 10-fold patient-level cross-validation, stratified by dislocation incidence.

Missing information

Exact image file formats and full demographic breakdown not specified.

Relationships between instances

Multiple preoperative AP pelvic/hip radiographs per patient (median 4 images per patient); temporal interval to surgery recorded and used for weighting/feature input.

Noise

Outcome is rare (2% 5-year dislocation), leading to class imbalance.

Confidentiality

De-identified imaging; HIPAA compliant.

Re-identification

Images and data were de-identified; IRB waiver of consent obtained.

Sensitive data

Clinical variables include demographics, comorbidities, and surgical characteristics; PHI removed before analysis.
