  • Combined Lateral Calcaneal Lengthening Osteotomy and Dynamic Soft Tissue Reconstruction of Medial Foot in Adolescent Flexible Flatfoot

Abstract The objective of this study was to evaluate the operative management of flexible flatfoot in adolescent by calcaneal lengthening osteotomy described by Evans and dynamic soft tissue reconstruction of medial foot. To elevate the collapse of the medial longitudinal arch on the weight bearing state and correct the deformity which has three components heel valgus, forefoot abduction in addition to collapse of the medial longitudinal arch and centralizes the motion of the subtalar joint. Methods: In our study, (42) feet in (21) patients who had symptomatic flatfoot were treated with lateral calcaneal lengthening (LCL) osteotomy, accessory navicular excision, anatomical reconstruction of the spring ligament complex (internal brace) augmentation and flexor digitorum longus (FDL) transfer to tibialis posterior tendon (TPT) and gastrocnemius recession. After LCL medial longitudinal arch is reestablished and soft tissues of medial foot usually require reconstruction. Thus, we decided to perform combination surgeries, we believe that using (FDL), as reported in this study, is a more anatomically correct procedure, supporting (TPT) without harmful effect on foot function, while simultaneously checking spring ligament.

  • Evaluation of Clinical and Radiological Results of Calcaneal Lengthening Osteotomy in Pediatric Idiopathic Flexible Flatfoot
    )402( COPYRIGHT 2018 © BY THE ARCHIVES OF BONE AND JOINT SURGERY RESEARCH ARTICLE Evaluation of Clinical and Radiological Results of Calcaneal Lengthening Osteotomy in Pediatric Idiopathic Flexible Flatfoot Taghi Baghdadi, MD; Hamed Mazoochy, MD; Mohammadreza Guity, MD; Nima Heidari khabbaz, MD Research performed at Imam Khomeini Hospital, Tehran University of Medical Sciences, Tehran, Iran Received: 20 January 2018 Accepted: 21 April 2018 Abstract Background: Flexible idiopathic flatfoot is the most common form of flatfoot. First line treatments are parental reassurance and conservative measures; however, surgical treatment may be needed in some cases. A number of surgical techniques with varying results have been described in the literature. Here, we present our clinical and radiological outcomes of calcaneal lengthening osteotomy for pediatric idiopathic flexible flatfoot. Methods: Calcaneal lengthening osteotomy was performed in 20 patients, 30 feet, with idiopathic flexible flatfoot that were resistant to conservative treatment between 2007 and 2011. Patients were evaluated according to ACFAS universal evaluation scoring scale and radiographic indexes. The mean follow up duration was 23.1 ± 9.9 months. Results: The average age was 10.4 ± 0.9 years. Achilles tendon lengthening was performed in 28 feet. ACFAS score at the final follow up had improved significantly compared to pre-operative score (37 to 88, P<0.0001). Radiographic parameters also showed significant improvement after surgery ((P<0.0001)). Distal segment displacement and hardware irritation as postop complications were observed in 2 and 3 cases, respectively, with no long-term clinical impact. Conclusion: Calcaneal lengthening osteotomy is an appropriate and safe operation in symptomatic idiopathic flexible flat foot that is resistant to conservative treatment.

  • Midfoot Plating Techniques
    Midfoot Plating Techniques Surgical Technique Midfoot Plating Techniques Lapidus Plate Designed to provide excellent fixation for a lapidus procedure, the Lapidus Plate offers the foot & ankle surgeon an anatomically contoured and configured option for procedures in the midfoot. The slot in this low profile plate allows the surgeon the choice of placing a lag screw across the TMT joint, as an outrigger screw to the 2nd metatarsal, or simply in offset compression mode. The surgeon may also choose to place locking or nonlocking screws in the other three plate holes. Locking Option – The two proximal and most distal holes allow the surgeon to choose a fixed-angle locking or variable-angle nonlocking option, depending on the needs of the patient Compression Option – The inner slot can accomodate an interfragmentary screw or generate compression when drilled eccentrically Minimized Profile – Low Profile Plates and screw heads reduce soft tissue irritation and the need for removal Arthrex LPS Lapidus Plate Two 4 mm Solid Crossed Screws Anatomic Contour – Optimizes construct strength, simplifies surgical technique and reduces soft tissue irritation ULTIMATE LOAD-TO-FAILURE Anodized Finish – Dramatically improves smoothness 120 100 Screw Options – 3.5 mm cortical, locking and 4 mm cancellous 80 60 Newtons 40 20 0 *data on file Midfoot Fusion with Lapidus Plate Lag Screw through the Plate Outrigger Screw through the Plate H-Plates Designed to provide excellent fixation for fusions and osteotomies, these plates offer the foot & ankle surgeon a comprehensive option for procedures in the midfoot.
