Study of Romosozumab (AMG 785) in Tibial Diaphyseal Fractures Status Post Intramedullary Nailing

Change From Week 8 in Short Form (36) Health Survey Physical Functioning Domain

The Medical Outcome Study Short Form 36-Item Health Survey (SF-36), Version 2, is a self-administered instrument that measures the impact of disease on overall quality of life and consists of 36 questions in eight domains (physical function, pain, general and mental health, vitality, social function, physical and emotional health). The physical functioning domain includes 10 questions that assess limitations in physical activities because of health problems. Norm-based scores were used in analyses, calibrated so that 50 is the average score and the standard deviation equals 10. The range of SF-36 physical functioning is 14.94 - 57.03. Higher scores indicate a higher level of functioning. A positive change from baseline score indicates an improvement in physical functioning.

Time frame: Week 8 and weeks 12, 16, 20, 24, 36, and 52

Number of Participants With Unplanned Revision Surgeries

Time frame: 52 weeks

Time to Clinical Healing

Time to clinical healing was defined as the time from the IM nailing surgery date to the first date that both the score for ability to bear weight on the fractured limb and the score for absence of pain at the fracture site were equal to 6. The score for the ability to bear weight on the fractured limb was based on the ability to stand on affected leg without assistive device and the ability to walk without assistive device. The score ranges from 0 (unable to bear full body weight on the fractured limb) to 6 (able to bear full body weight on the fractured limb). Absence of pain at the fracture site was based on the absence of pain at the fracture site when applying direct pressure to the fracture site and applying a stress to the fracture site. The score ranges from 0 (pain without palpation at fracture site) to 6 (total absence of pain at fracture site). Time to clinical healing was estimated using CIF; unplanned revision surgery was considered a competing risk in CIF estimate.
