Flexible flatfoot is a frequent deformity found in children. The aim of this study is to evaluate the pedographic outcome of the percutaneous arthroereisis with the use of a screw through the sinus tarsi into the talus. MATERIALS AND
43 calcaneo-stop procedures of 25 patients (18 bilateral, seven unilateral) were evaluated. Mean age at surgery was 10 years (7-14, SD 2.2) (
standard deviation), mean follow-up time was 9.7 months (3-19, SD 5.5). Patient satisfaction rate was recorded, the Meary's talus-first metatarsal angle was measured with lateral radiograms, and a dynamic pedographic assessment was also performed.
Patient satisfaction rate was excellent for 33 feet of 19 children, good for eight feet of five children, and poor for either feet of one child. We did not observe any complications during or following the surgery.The mean rest heel valgus decreased from 13.4° (10°-17°, SD 1.5) to 2.8° (0°-6°, SD 1.7) post op. The Meary's angle improved from 160.2° (148°-177°, SD 6.8) to 175.9° (167°-179°, SD 3.5). By pedographic analysis, the area and the pressure-time integral (load amount, PTI) values increased on the lateral regions of the sole (except for the lesser toes) and decreased on the medial areas (except for the hallux). The relative contact time in the lateral midfoot increased from 63.8% (39.6-78.4%, SD 10.6) to 75.1% (50-86.1%, SD 9.4), and that in the lateral forefoot region from 81.2% (60.4-89.2%, SD 6.6) to 86.8% (78.1-97.1%, SD 4.8).
The calcaneo-stop procedure is a simple and reliable method for the correction of severe flexible paediatric flatfoot. Our prospective, short-term results following the anterograde screw implantation into the talus correlate well with the results of similar or different arthroereisis methods. Further investigations are required to evaluate the long-term outcome of the screw calcaneo-stop method, including the conditions following implant removal.

To evaluate the therapeutic outcomes with Kalix II subtalar arthroereisis in sinus tarsi for juvenile flexible flatfoot.
The aim of this study was to establish whether children treated with subtalar arthroereisis for flexible flatfoot were able to return to sport activities. We reviewed 49 patients with a mean age at th...
Koutsogiannis' osteotomy has been widely described to treat adult-acquired flatfoot. However, few articles describe its midterm follow-up. Our aim was to study clinical and radiological outcomes at le...
It is usually accepted that acquired flatfoot deformity after injury is usually due to partial or complete tear of the posterior tibial tendon (PTT), with secondary failure of the other structures whi...
Flexible ureteroscopy has been widely developed in the last decade been nowadays one of the first line treatment options for urolithiasis and conservative management for upper tract urothelial tumors....
The purpose of this study is to compare computer aided design/computer aided manufacturing (CAD/CAM) and semi-custom insole types on pain, quality of life and physical performance and also...
The purpose of this study is to investigate the efficay of functional plantar orthoses on flatfoot in children.
The purpose of this study is to determine whether ketamine or propofol, drugs used for procedural sedation during paediatric bronchoscopy, results in higher operator satisfaction and bette...
The purpose of this work is to estimate the efficiency in terms of pain of the application of a local anesthetic (xylocaïne viscous 2%®) during the realization of an examination in naso-...
The objective of the study was to establish which anesthetic procedure used during flexible bronchoscopy has the lowest index of complications.
An mRNA metabolic process that distinguishes a normal STOP CODON from a premature stop codon (NONSENSE CODON) and facilitates rapid degradation of aberrant mRNAs containing premature stop codons.
A procedure to stop the contraction of MYOCARDIUM during HEART SURGERY. It is usually achieved with the use of chemicals (CARDIOPLEGIC SOLUTIONS) or cold temperature (such as chilled perfusate).
A condition characterized by a broad range of progressive disorders ranging from TENOSYNOVITIS to tendon rupture with or without hindfoot collapse to a fixed, rigid, FLATFOOT deformity. Pathologic changes can involve associated tendons, ligaments, joint structures of the ANKLE, hindfoot, and midfoot. Posterior tibial tendon dysfunction is the most common cause of acquired flatfoot deformity in adults.
A condition in which one or more of the arches of the foot have flattened out.
An amino acid-specifying codon that has been converted to a stop codon (CODON, TERMINATOR) by mutation. Its occurance is abnormal causing premature termination of protein translation and results in production of truncated and non-functional proteins. A nonsense mutation is one that converts an amino acid-specific codon to a stop codon.
Pediatrics is the general medicine of childhood. Because of the developmental processes (psychological and physical) of childhood, the involvement of parents, and the social management of conditions at home and at school, pediatrics is a specialty. With ...
