Treatment Of Symptomatic Pes Planus By Sinus Tarsi Screw Versus Conical Subtalar Screw Arthroereisis

Study Overview
=================
Brief Summary
-----------------
compare the outcome of surgical treatment planus by sinus tarsi screw versus conical subtalar screw arthroereisis

Detailed Description
-----------------
Pes planus occurs as a result of loss of the medial longitudinal arch, abduction of the forefoot and excessive subtalar eversion. It can broadly be categorized as rigid or flexible.(1) Flexible pes planus has no single identifiable cause and is often asymptomatic.(1-3) Patients with pesplanus had a very tight achilles tendon due to compensatory motion.(4) It can become painful and may require orthopaedic or pediatric intervention. Common treatment modalities include rest, physiotherapy, orthotics and anti-inflammatories.(1,3,5-6) Surgery is uncommon unless pain persists in spite of nonsurgical management.(5-6) Surgical options include soft tissue procedures, realignment osteotomies and non-fusion motion-limiting techniques.(1,2,6-9) Fusion of selected joints in the foot is not recommended in paediatric patients unless associated with a neuromuscular pathology.(1,5) Subtalar arthroereisis is a recognized non-fusion surgical treatment for symptomatic paediatric flexible pes planus. Arthroereisis (also arthroreisis, arthrorhisis or arthrorisis) derives from Greek, translated as to prop up or support a joint.(10) When Flexible pes planus becomes symptomatic, affecting gait and limiting quality of life, and conservative treatment such as weight reduction, physiotherapy or insoles fail, operative treatment can be considered .(7) There are two techniques for subtalar arthroereisis: (11) Insertion of an implant directly into the sinus tarsi to prevent it collapsing down. (10) Screw insertion into the lateral side of either the talus or calcaneus(12). Calcaneo-stop method with cancellous screw insertion into sinus tarsi for subtalar arthroresis is a valid procedure for this multiplanar deformity. Maintaince of correction of the deformity is achieved via a prioprioceptive mechanism. (13) The current research is the first one to compare the clinical , radiological,and patient satisfaction outcome of planovalgus cases treated with two different types of subtalar arthroereisis implants . The purpose of this prospective study is to show the best technique to achieve patient satisfaction.

Primary Outcome Measures

| to identify and evaluate the comparison between two technical procedure of surgical treatment of symptomatic pes planus by sinus tarsi screw versus conical subtalar screw arthroerasis using American Orthopaedic Foot and Ankle Society scores (AOFAS) | American Orthopedic Foot & Ankle Society (AOFAS) ankle-hind foot score was assessed. The total AOFAS score 100 points divided to 40 points for assessment of pain, 50 points for the functional assessment  activity limitations, maximum walking distance, gait abnormality…etc and 10 points for assessment of the alignment. | 2 years |
