Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This single-centre historical control group comparative study will compare outcomes of surgically-treated rotational ankle fractures and the current routine practice of early protected weightbearing and range of motion with immediate unprotected weightbearing as tolerated and range of motion after ankle open reduction and internal fixation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Ankle fractures are among the most common injuries, making up 9% of all fractures. Rotational ankle fractures are among the most common of all fractures, with an incidence averaging 4.2 per 1,000 individuals annually. These fractures range from minimal injuries amenable to non-surgical management to complex injuries with potential of long-term sequelae. Known risk factors for ankle fractures are age, body mass index and previous ankle fracture, with the highest incidence in elderly women.

Most ankle fractures are low-energy injuries which occur when the body rotates about a planted foot, whether it be during sports, normal gait, or otherwise. Stable ankle fractures are generally treated non-surgically, while unstable fractures are usually treated with surgical reduction and fixation, with indications previously well-described and published.

However, the post-operative management of such injuries is still controversial, with large variability between care providers. Protocols range from complete immobilization of the affected ankle and non-weightbearing to early range-of-motion (ROM) and weightbearing (WB). Studies have compared immobilization and non-WB to early ROM and WB but results have been mixed, with the most recent study demonstrating safety and advantages to protected WB and ROM at two weeks post-operatively versus non-WB and immobilization for six weeks.

The Investigators intend to expand on the studies above and propose a single-centre historical control group comparative study to compare outcomes of surgically-treated rotational ankle fractures and the current routine practice of early protected weightbearing and range of motion with immediate unprotected weightbearing as tolerated and range of motion after ankle open reduction and internal fixation.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Late WB

Intervention: Patients receive a plaster splint in the operating room. They are not permitted to WB or ROM on the affected limb at this stage. At the first follow-up appointment (two weeks post-op), the splint is removed and a removable pre-fabricated walking boot applied. At this stage the patient is permitted to WB as tolerated while wearing the boot, and to perform ROM exercises with the boot removed. At six weeks post-op, the boot is discontinued and full unrestricted and unprotected weightbearing and ROM is permitted.

Group Type ACTIVE_COMPARATOR

Late Rehabilitation

Intervention Type OTHER

Post-0p: Non weight-bearing and no range of motion for 2 weeks post treatment. 2 weeks: Splint removed, removable pre-fabricated walking boot applied. WB as tolerated with boot, range of motion out of boot.

6 weeks: Boot discontinued and full unrestricted and unprotected WB and ROM permitted 6 weeks:

Immediate unprotected WB and ROM

Patient do NOT receive a brace or splint of any kind. They are permitted to weightbear and range of motion as tolerated within the limitations of their own comfort. Use of ambulatory aids of any kind is permitted as needed without restrictions.

Group Type EXPERIMENTAL

Early Rehabilitation

Intervention Type OTHER

Weightbearing and range of motion as tolerated within the limitations of participant's own comfort. Use of ambulatory aides of any kind is permitted as needed without restriction. No brace or splint of any kind is permitted
