About

The purpose of this study is to compare the Trigen InterTAN Intramedullary nail to Sliding Hip Screws in AO/OTA 31-A1 and A2 intertrochanteric hip fractures.

Full description

A multicentre, randomised controlled trial, conducted in the UK will recruit 180 subjects, randomised to receive either the Trigen InterTAN Nail or the Sliding Hip Screw.

Subjects presenting at participating hospitals with AO/OTA 31-A1 or A2 fractures will be assessed against the eligibility criteria and approached for Informed Consent.

Subjects who are considered eligible and who have provided Informed Consent will be randomised using iDataFax to one of the two treatment options.

Subjects will be operated on according to standard procedure and the Instructions for Use.

A daily inpatient assessment will record the subjects use of opioid pain medication.

Subjects will be assessed at the time of discharge to record their residential and ambulatory status, Functional Independence Measure, Get Up and Go Test and opioid usage.

At 8 weeks and 12 weeks post surgery, subjects will be contacted by telephone to confirm their residential and ambulatory status, Functional Independence Measure, modified Harris Hip Score and Euroqol-5D.

At 6 months post surgery, subjects will attend an outpatient visit to have a follow up radiograph, Get Up and Go Test, residential and ambulatory status, Functional Independence Measure, modified Harris Hip Score and Euroqol-5D.

At 12 months post surgery, subjects will be contacted by telephone to confirm their residential and ambulatory status, Functional Independence Measure, modified Harris Hip Score and Euroqol-5D.

Adverse events, device deficiencies and reoperations will be recorded as and when they occur throughout the study.

34 participants in 2 patient groups

Trigen Intertan

Other group

Description:

* Unique integrated interlocking screw and trapezoidal nail shape * Resistance to femoral head rotation and cut-out * Active compression through linear motion without rotation * Single subtrochanteric lag screw option for stable fractures below lesser trochanter * Preloaded cannulated set screw converts construct to fixed angle device * Small proximal diameter of the nail promotes preservation of the lateral wall of the greater trochanter and gluteus medius tendon * Clothespin tip for stress modulation in femoral shaft * Potential for improved patient mobility and recovery Manufactured by Smith \& Nephew Inc., 1450 Brooks Road, Memphis, TN 38116, U.S.A. Interventions: Randomisation to either Trigen Intertan or Sliding Hip Screw, Post-Surgery Follow Up

Other: Post-Surgery Follow Up

Device: Trigen Intertan

Sliding Hip Screw

Other group

Description:

SHS is a generic term for a group of devices used for internal fixation of trochanteric hip fractures. Also known as Compression Hip Screw or Dynamic Hip Screw. All devices feature a lag screw inserted into the femoral neck and a side plate held in place by cortical screws inserted into the proximal femoral shaft. Therapeutic effect is achieved by guided collapse, where the lag screw can slide in the barrel of the side plate which compresses the fracture as the patient begins to weight-bear. Participating sites may use whichever brand of SHS is currently in use. Interventions: Randomisation to either Trigen Intertan or Sliding Hip Screw, Post-Surgery Follow Up
