Background Acute total hip arthroplasty (THA) may be an alternative or an adjuvant to internal fixation for surgical treatment of acetabular fractures. We investigate recent trends in the operative management of acetabular fractures. We hypothesize that the incidence of acute THA for acetabular fractures has increased over time. Methods 4569 middle-aged (45–64 years) and older adults (≥ 65 years) who received acute operative management of an acetabular fracture within 3 weeks of admission between 2010 and 2020 were identified from the United States Nationwide Inpatient Sample database. Treatment was classified as open reduction internal fixation (ORIF), THA, or combined ORIF and THA (ORIF + THA). Patients were stratified by age ≥ 65 years old. Associations between demographic factors and the incidence of each procedure over the study period were modeled using linear regression. Results The relative incidence of treatments was 80.9% ORIF, 12.1% THA, and 7.0% ORIF + THA. Among patients aged 45–64 years old, THA increased 4.8% [R2 = 0.62; β1 = 0.6% (95% Confidence Interval (CI) 0.2–0.9%)] and ORIF + THA increased 2.6% [R2 = 0.73; β1 = 0.3% (95% CI 0.2–0.4%)], while the use of ORIF decreased 7.4% [R2 = 0.75; β1 = −0.9% (95% CI −1.2 to −0.5%)]. Among patients ≥ 65 years old, THA increased 16.5% [R2 = 0.87; β1 = 1.7% (95% CI 1.2–2.2%)] and ORIF + THA increased 5.0% [R2 = 0.38, β1 = 0.6% (95% CI 0.0–1.3%)], while ORIF decreased 21.5% [R2 = 0.75; β1 = −2.4% (95% CI −3.45 to −1.3%)]. Conclusion The treatment of acetabular fractures with acute THA has increased in the last decade, particularly among older adults.

Rationale: The rationale was to establish a permanent surgical solution for nonreducing dislocations of the temporomandibular joint (TMJ). Patient Concerns: The patient presents with a long-standing history of chronic subluxation of the TMJ bilaterally, with the need to forcibly manipulate and reduce the dislocated jaw. Diagnosis: Chronic recurrent dislocation of the TMJ. Treatment: A modified Dautrey's procedure was performed on the right side, with the osteotomized segment being transferred medially and inferiorly. Outcome: After 5 years of follow-up, there was no incidence of recurrent dislocation. Take-away Lesson: This modification is a viable option in both unilateral and bilateral reducing and nonreducing dislocations.
