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. J. Surg.
