Objective: To compare the responsiveness of the Short Form-36 (SF-36) physical component score (PCS) to the Short Musculoskeletal Function Assessment (SMFA) dysfunction index (DI) in pelvic and acetabular fracture patients over multiple time points in the first year of recovery.
Design: Prospective cohort study.
Setting: Level 1 trauma center.
Patients/participants: Four hundred seventy-three patients with surgically treated pelvic and acetabular fractures (Orthopaedic Trauma Association B or C-type pelvic ring disruption or acetabular fracture) were enrolled into the center's prospective orthopaedic trauma database between January 2005 and February 2015. Functional outcome data were collected at baseline, 6 months, and 12 months.
Main Outcome Measurements: Evaluation was performed using the SF-36 Survey and Short Musculoskeletal Function Assessment. Responsiveness was assessed by calculating the standard response mean (SRM), the minimal clinically important difference (MCID), and floor and ceiling effects.
Results: Three hundred five patients had complete data for both outcome scores. SF-36 PCS and SMFA DI scores showed strong correlation for all time intervals (r = -0.55 at baseline, r = -0.78 at 6 months, and r = -0.85 at 12 months). The SRM of the SF-36 PCS was greater in magnitude than the SRM of SMFA DI at all time points; this was statistically significant between baseline and 6 months ( < .001), but not between 6 and 12 months ( = .29). Similarly, the proportion of patients achieving MCID in SF-36 PCS was significantly greater than the proportion achieving MCID in SMFA DI between baseline and 6 months (84.6% vs 69.8%, < .001), and between 6 and 12 months (48.5% vs 35.7%, = .01). There were no ceiling or floor effects found for SF-36 PCS at any time intervals. However, 16.1% of patients achieved the highest level of functioning detectable by the SMFA DI at baseline, along with smaller ceiling effects at 6 months (1.3%) and 12 months (3.3%).
Conclusions: SF-36 PCS is a more responsive measure of functional outcome than the SFMA DI over the first year of recovery in patients who sustain a pelvic ring disruption or acetabular fracture. This superiority was found in using the SRM, proportion of patients meeting MCID, and ceiling effects. Furthermore, the SF-36 PCS correlated with the more disease-specific SMFA DI.
Level Of Evidence: Prognostic Level II.

Acetabular fractures are rare fractures of the pelvis which usually result from trauma. Whilst data are reported on sexual and genitourinary function in those with pelvic fractures, less is known about those with isolated acetabulum fractures. This systematic review aimed to determine, first, the frequency of sexual and genitourinary dysfunction following isolated acetabulum fractures and, second, the nature of these complications.

Background: Femoroacetabular impingement (FAI) is a well-recognized cause of hip pain in adults. The hip-spine relationship between the femur, pelvis, and lumbosacral spine has garnered recent attention in hip arthroplasty. However, the hip-spine relationship has not been well described in patients with FAI.

Background: Developmental dysplasia of the hip (DDH) encompasses a spectrum of pathological conditions, including dislocation, subluxation, and deformities of the femoral head and acetabulum. The optimal surgical approach for DDH remains a subject of debate. Successful treatment aims to achieve a stable concentric reduction and prevent future subluxation or dislocation.

Hominin pelvic form differs dramatically from that of other primates by having more laterally facing iliac blades, a wider sacrum, and a larger, transversely broad pelvic inlet. The orientation of the acetabulum may also differ, plausibly related to differences in load transmission during upright posture and habitual bipedal locomotion, which may, in turn, affect overall pelvic geometry. We compared acetabular orientation in humans, a phylogenetically broad sample of extant anthropoid primates, and fossil hominins including Australopithecus afarensis (A.

Rationale And Objectives: Accurate assessment of hip morphology is crucial for the diagnosis and management of hip pathologies. Traditional manual measurements are prone to mistakes and inter- and intra-reader variability. Artificial intelligence (AI) could mitigate such issues by providing accurate and reproducible measurements.
