Outcome Measures

Primary Outcomes (1)

  • SMFA (Short Musculoskeletal Function Assessment Questionnaire)

    46 question score. Patients are asked to tick boxes labelled between 1 (indicating good function/no problems) and 5 (poor function/significant problems) for each question and the responses are used to calculate a "dysfunction index", a "bother index" and an "overall SMFA score". These will be reported for each group with measure of central tendency (mean/median) and standard deviations/interquartile range.

    final followup/one year

Secondary Outcomes (17)

  • SMFA (Short Musculoskeletal Function Assessment Questionnaire)

    At the initial review, upon enrolment in the study, patients are asked to complete the questionnaire detailing their immediate pre-injury status (ie status one day before injury). Then reassessed at 26 weeks.

  • Incidence of thromboembolic events

    1 year

  • Ankle and subtalar motion

    10, 26 and 52 weeks

  • Calf circumference

    10, 26 and 52 weeks

  • Visual Analogue Score (VAS) for pain

    Initial review, 4,8,10,26,52 weeks.

  • +12 more secondary outcomes

Study Arms (2)

Standard treatment protocol

ACTIVE COMPARATOR

Cast immobilisation with 4 weeks in equinus cast (non-weight bearing) followed by 4 weeks in semi-equinus cast (non-weightbearing) and 2 weeks in neutral cast (full weightbearing). At this point, the cast is removed and patients mobilise fully weightbearing for a further 2 weeks out of cast, with internal shoe insert heel raise. Commence physiotherapy at 10 weeks, when cast removed.

Other: Standard treatment protocol

Accelerated rehabilitation

EXPERIMENTAL

4 weeks in Ossur rebound walking boot with 2 heel wedges (3cm), 2 weeks in Ossur rebound walking boot with 1 heel wedge (1.5cm) and 2 weeks in Ossur rebound walking boot with no heel wedges (neutral position). Fully weightbearing throughout. Commence physiotherapy at 8 weeks.

Other: Accelerated Rehabilitation

Interventions

Cast Protocol 4 weeks in Full Equinus cast - Non Weight Bearing (NWB) with axillary crutches; 4 weeks in Semi-Equinus cast NWB with axillary crutches; 2 weeks in neutral cast - Full Weight Bearing (FWB); 2 weeks FWB out of cast, with shoe insert heel raise. Followed by course of physiotherapy

Standard treatment protocol

4 weeks in Ossur Rebound walking boot with 3cm heel raise, worn continuously including in bed. Weight bearing as tolerated (WBAT)/FWB - crutches for balance; 2 weeks in Rebound walking boot with 1.5cm heel raise (WBAT/FWB - crutches for balance; 2 weeks in Rebound walking boot with foot in neutral. At 8 weeks, remove boot and allow FWB out of boot. At 8 weeks after initiation of treatment, physiotherapy is commenced.
