Kidner vs. Hypocure

Hyprocure is in fact Sinus tarsi implant insertion in the foot and is not appropriate for most children with mobile flatfoot. The procedure may be used in selected children with persistent mobile flatfoot due to neuromuscular disorder, skeletal dysplasia or systemic ligamentous laxity, whose treatment is supervised by a multidisciplinary team. The procedure may be indicated rarely in patients where orthotics and physiotherapy has failed.
The procedure (also known as subtalar arthroereisis) can be performed with the patient under general or local anaesthesia. Exact technique and instrumentation vary. The sinus tarsi (between the calcaneum and the talus) is accessed by a lateral incision. A trial implant may be used, with intraoperative imaging and simulated weight bearing, to direct appropriate placement and degree of correction before a sized implant is inserted. Adjunctive bone or soft tissue procedures may also be carried out. Compression dressing or plaster cast (particularly with adjunctive procedures) and modified footwear and/or orthotics may be used postoperatively. The implant may need to be removed, particularly in children; exact timing for this varies.
In a case series study of 54 patients (68 feet), 59% (22/37) reported pain before and 5% (2/37) after the procedure (mean follow-up 26.5 months). In a case series of 23 patients (28 feet), the mean pain score decreased from 3.2 preoperatively to 1.6 postoperatively on a scale from 4 (severe pain) to 1 (no pain) (p < 0.0001) (mean follow-up 44 months).

 

Thank you very much for your feedback.
My daughter has tried physio, massage therapy, chiro, sports taping, orthotics and has very lax ligaments in all her joints.

It seems like the stats below suggest a huge amount of pain reduction after the procedure. The Kidner option seems to have a much higher rate of complication. In Canada where we live, the cost of the kidner treatment is free under our health coverage. The implant is $7000 and is not covered.

Can I ask a follow up question based on your reply - why would the implant need to be removed in a child?
