Overview

• Pathology
• - Mechanics of hip dislocation
• Principles of hip bracing-
• - Current bracing modalities
• Design objectives of Hiptric
• Features and benefits
• Conclusion

3
Hip Dislocation

• Incidence between 1- 3 of primary hip
  replacements
• Many factors affecting risk of dislocation
• Often results in
• Significant pain
• Anastheasia
• Prolonged hospital stay
• Potential revision surgery

4
Mechanism of Dislocation

• Posterior dislocations are most common
• Often due impingement of the hip components
• High risk movements
• Flexion
• Adduction
• Internal rotation

5
Dislocation Risk Factors

• Patient related factors
• Age
• Gender
• Prior surgery or fracture
• Dementia
• Neuromuscular related weakness

6
Surgical Risk Factors

• Incorrect prosthesis positioning
• Poor tension/ length of tissues around the hip
• Poor restoration of leg length
• Surgical technique
• Small femoral head/ thick femoral neck components

7
Prosthesis Related Risk Factors
8
Principles of Hip Bracing

• Current hip orthoses have static force systems
• Patient is held in abduction at all times
• Orthosis is
• Bulky
• Heavy
• Uncomfortable
• Uncosmetic
• Problematic to toilet with it on

9
Design Objectives

• Improve current hip abduction braces
• Effectiveness
• Ease of use
• Compliance
• Reduction of bulk
• Cosmesis
• Ease of toileting

10
Indications

• Primary arthroplasty patients at risk to
  dislocate
• Post-op revision patients
• Preventative (prophylactic) use
• Non-operable hip abnormalities
• Post hip arthroscopy

11
Hiptric - Features and Benefits

• Dynamic abduction force
• Security
• Hinge-free design
• Sliding joint mechanism
• Modular system
• Comfort
• Easy application
• Low profile
• Proven

12
Hiptric - Dynamic Abduction Force

• Constant, gentle force to the affected side
  throughout entire range of motion
• 3-pt force system
• Allows for normal gait pattern
• Keeps femoral head centered in acetabulum

13
Hiptric - Security

• Easy to adjust flexion and extension stops
• Spring rod can be adjusted with bending irons to
  control the amount of abduction
• Pre- set to 10- 15 abduction force

14
Hiptric - Hinge-Free Design

• Provides abduction force even when sitting and
  ascending stairs

Conventional Orthosis
Hiptric
15
Hiptric - Sliding Joint Mechanism

• Accurately follows the anatomical motion of the
  hip joint
• Telescoping spring rod in hip plate
• Maintains abduction control
• Less upward migration in sitting

16
Hiptric - Modular System

• 4 softgood sizes
• 3 brace lengths
• All interchangeable
• No height adjustments necessary
• Can be used on either the right or left side

17
Hiptric - Comfort

• Aerospacer liner
• Adjustable thigh pad prevents pressure on
  incision
• Lightweight/less bulky
• Soft, anatomical softgood materials

18
Hiptric - Ease of application

• Pelvic bandage is easy to apply in supine
  position
• Finger pockets in softgood
• Colour coded velcro
• Single tool for any necessary adjustments

19
Hiptric - Low Profile

• Minimal plastic parts
• Ultra thin softgood
• No hip joint
• Can be worn under clothing

20
Hiptric - Proven (clinical trial)

• 26 patients sample size
• 6 male 20 female
• Average age 79 Years
• Number of dislocations before Hiptric range 0-7
  times
• 14 patients already had a conventional orthosis
  (Newport or other)
• Results collated at 4 and 8 weeks

21
Hiptric - Clinical Trial Results
22
Hiptric - Clinical Trial Results

• Only 1 dislocation ( 3.85 )
• 12 out of 14 patients preferred the Hiptric
• 1 patient had preference for conventional
  orthosis
• 1 patient had no preference

23
Hiptric - Sizing

• Hip Circumference
• Around iliac crests
• Determines softgood size
• Length
• from greater trochanter to mid patella
• Determines length of spring rod
• 3 lengths available S/M/L

24

25
Hiptric - Unique Post-Surgical Protection

• Effective
• Unique
• Compliant
