Functional outcomes and gait analysis of patients after periacetabular sarcoma resection with and without ischiofemoral arthrodesis
Bibliographic record
Abstract
BACKGROUND: Treatment of periacetabular sarcomas remains a difficult challenge. Many reconstruction options are fraught with high complication and failure rates. Little is known about patients' functional outcomes, and there have been no studies that examine how these reconstructions affect patients' gait parameters. The purpose of this study is to evaluate gait parameters and functional outcome in patients whom have undergone periacetabular resections with either an ischiofemoral pseudoarthrodesis or soft tissue reconstruction only. METHODS: Ten patients with sarcoma of the periacetabular region were identified from our database. Functional outcome was assessed using the Musculoskeletal Tumor Society Scores (MSTS) and Toronto extremity salvage score (TESS) scoring systems. Gait analysis was performed on all subjects. RESULTS: Patients in both surgical groups had average functional scores. All patients were ambulatory. Cadence and velocity in the surgical group were significantly slower than the control group, however, the remainder of the gait parameters examined were similar to controls. CONCLUSION: Patients who underwent minimal reconstruction following periacetabular resections demonstrated average functional scores, comparable to those undergoing more extensive reconstructions. With the exception of speed, gait parameters were not significantly different than controls. Complication rates were low. Pseudoarthrodesis or even no bone reconstruction following periacetabular resection is reasonable and functional options for many of these patients.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
