Clinical Trial Summary

Evaluate clinical healing and radiographic maintenance of correction following an LCL procedure or medial cuneiform osteotomy (Cotton) at 6 months following the use of the TITAN 3-D™ Wedge. Subjects who receive one or more TITAN 3-D™ Wedges will obtain satisfactory levels of clinical healing and radiographic maintenance of correction at 6 months.

Study Design


Intervention

Device:
Titan 3D Wedge System
Each subject will undergo an LCL procedure and/or medial cuneiform osteotomy with one or more TITAN 3-D™ Wedges. Ancillary fixation should be used in conjunction with each TITAN 3-D™ Wedge used. This surgical procedure will be performed as standard of care and is not part of the research procedures. Post-operative care and weight-bearing/activity restrictions will be at the discretion of the surgeon as part of their standard of care for the procedure.

Outcome

Type Measure Description Time frame Safety issue
Primary Clinical Healing Evaluate clinical healing following an LCL procedure or medial cuneiform osteotomy (Cotton) at 6 months following the use of the TITAN 3-D™ Wedge. Clinical healing is defined as lack of pain over the osteotomy site. 6 Months
Primary Radiographic Maintenance of Correction Evaluate radiographic maintenance of correction following an LCL procedure or medial cuneiform osteotomy (Cotton) at 6 months following the use of the TITAN 3-D™ Wedge. Radiographic maintenance of correction is defined as the absence of a clinically relevant change in radiographic measures across post-operative time points. 6 Months
Secondary Time to clinical/radiographic healing (union) Evaluate time to clinical/radiographic healing (union vs. non-union) after a Titan 3D wedge procedure 24 Months
Secondary Clinical complications Complications due to the procedure 24 Months
Secondary Maintenance of implant position 24 Months
Secondary Maintenance of anatomical alignment 24 Months
Secondary Determine bone reaction, if any, to the device such as overgrowth or cystic lesions 24 Months
Secondary Determine rate of removal of the device and subsequent healing 24 Months
Secondary Change in anatomical and radiographic angular/positional alignment before and after an LCL procedure and/or medial cuneiform osteotomy using a TITAN 3-D™ Wedge 24 Months
Secondary Change in VAS Pain Score across multiple time points Visual Analog Scale (VAS). Line from 0 (no pain) to 10 (worst pain). Patient reported. Pre-operatively, 2 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months
Secondary Change in AOFAS Ankle-Hindfoot and/or Midfoot Score across multiple time points American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot clinical score.
Pain: 0-40 points Function: 0-50 points Alignment: 0-10 points Total Score (sum): 0-100 points (higher score indicates better outcomes)
American Orthopaedic Foot and Ankle Society (AOFAS) Midfoot clinical score. Pain: 0-40 points Function: 0-45 points Alignment: 0-15 points Total Score (sum): 0-100 points (higher score indicates better outcomes)
Pre-operatively, 2 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months
Secondary Change in PROMIS Pain Intensity Score across multiple time points Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Intensity Score, Item Bank v1.0, SF 3a.
Raw Score Range: 3 (no pain) to 15 (very severe pain)
Pre-operatively, 2 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months
Secondary Change in PROMIS Mobility Score across multiple time points Patient-Reported Outcomes Measurement Information System (PROMIS) Mobility Score, Item Bank v2.0.
Raw Score Range: 15 (high level of difficulty) to 120 (no difficulty)
Pre-operatively, 2 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months
Secondary Change in PROMIS Pain Interference Score across multiple time points Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference Score, Item Bank v1.0, SF 6a.
Raw Score Range: 6 (no interference) to 30 (high level of interference)
Pre-operatively, 2 weeks, 6 weeks, 12 weeks, 6 months, 12 months, 24 months
Secondary Compare the outcomes and complication rates of TITAN 3-D™ Wedges with previously published outcomes of historical controls, allograft bone and autograft bone 24 Months
