Related Articles Correction of a Severe Poliomyelitic Equinocavovarus Foot Using an Adjustable External Fixation Frame. J Foot Ankle Surg. 2013 Jul 24; Authors: Nomura I, Watanabe K, Matsubara H, Nishida H, Shirai T, Tsuchiya H Abstract One-stage surgical correction of severe equinocavovarus deformity can result in complications ranging from skin necrosis to tibial nerve palsy. Fewer complications have been reported when severe deformities were treated by gradual correction using external frames such as the Ilizarov external fixator or the Taylor Spatial Frame™. We describe a case of a 64-year-old female patient with severe poliomyelitic equinocavovarus whose deformity required her to ambulate using the dorsum of her right foot as a weightbearing surface. We treated the deformity with gradual correction using a Taylor Spatial Frame™, followed by ankle arthrodesis. At the most recent postoperative evaluation, 20 months after the initial surgery, the patient was pain free and ambulating on the sole of her right foot.

Related Articles The effect of shoe toe box shape and volume on forefoot interdigital and plantar pressures in healthy females. J Foot Ankle Res. 2013 Jul 25;6(1):28 Authors: Branthwaite H, Chockalingam N, Greenhalgh A Abstract BACKGROUND: Ill-fitting footwear can be detrimental to foot health with the forefoot being an area for most discomfort. Studies on footwear have primarily examined sports or orthopaedic prescription shoes and little is known about the effects that everyday flat shoes have on the forefoot. The aim of this study was to investigate the effect of toe box shape in a popular slip-on pump on dorsal and plantar pressures with particular interest around the forefoot in a healthy female population. METHOD: A convenience sample of 27 female participants with no known foot pathologies was recruited. After assessment of foot size, plantar foot pressure and interdigital pressures were recorded for each of the 3 different toe box styles; round, square and pointed. Participants walked at a self-selected speed over a 10 m walkway whilst wearing each of the 3 styles of shoe and also whilst barefoot. Processed and analysed data extracted included peak pressure, time to peak pressure, contact time and pressure time integral. ANOVA and Freidman analysis was used to test for statistical significance.

Related Articles Geometric morphometric footprint analysis of young women. J Foot Ankle Res. 2013;6(1):27 Authors: Domjanic J, Fieder M, Seidler H, Mitteroecker P Abstract BACKGROUND: Most published attempts to quantify footprint shape are based on a small number of measurements. We applied geometric morphometric methods to study shape variation of the complete footprint outline in a sample of 83 adult women. METHODS: The outline of the footprint, including the toes, was represented by a comprehensive set of 85 landmarks and semilandmarks. Shape coordinates were computed by Generalized Procrustes Analysis.

Related Articles Short-Term Functional Outcomes of First Metatarsophalangeal Total Joint Replacement for Hallux Rigidus. Foot Ankle Int. 2013 Jul 22; Authors: Erkocak OF, Senaran H, Altan E, Aydin BK, Acar MA Abstract BACKGROUND: Although metatarsophalangeal (MTP) arthrodesis has been advocated by many authors, implant arthroplasty appears to be successful option in advanced hallux rigidus (HR). The aim of our study was to evaluate the early results of the ToeFit-Plus prosthesis for the treatment of HR. METHODS: Between December 2007 and January 2011, a total of 26 toes of 24 patients with MTP arthritis of the great toe were treated with ToeFit-Plus implant. The average follow-up time was 29.9 (range: 25 to 62) months. All patients were evaluated clinically and radiographically. Postoperative satisfaction and function were scored according to the American Orthopaedic Foot and Ankle Society (AOFAS) score. Pain was assessed with the use of a visual analogue scale. RESULTS: Mean preoperative AOFAS score improved from 42.7 (range: 36 to 59) to 88.5 (range: 59 to 98) at the final follow-up (P < .01). Preoperative average visual analogue scale pain scores improved from 7.4 preoperatively to 1.9 at the final follow-up (P < .01). The average MTP joint range of motion improved from 25.9 degrees preoperatively to 53.8 degrees at the final follow-up. No radiologic loosening was found, but radiolucency was observed in 2 patients with this implant. No revision was required for any of the patients during the follow-up period.

Related Articles Bone Propeller Flap-A Staged Procedure. J Foot Ankle Surg. 2013 Jul 19; Authors: Tremp M, Largo RD, Borens O, Schaefer DJ, Kalbermatten DF Abstract The ideal reconstruction technique for complex defects of the lower limb consists of replacing tissue with similar tissue in an attempt to achieve a good functional result. A 23-year-old white male sustained a crush injury with a grade IIIB open ankle dislocation. After open reduction and fixation, the patient developed severe osteomyelitis at the tibiotalar joint requiring a staged and radical debridement with a substantial combined soft tissue and bony defect over the distal tibia, fibula, and talus area. The reconstructive approach consisted of a modified model of the propeller flap, implementing the spare part concept in a 2-stage procedure using a prefabricated and vascularized "double-barrel" fibular graft. At 17 months postoperatively, a plain radiograph showed bony union with complete and stable coverage of the soft tissue defect. The patient was fully weightbearing. In conclusion, there is evidence to suggest that the established concept of a soft tissue propeller flap can be implemented on bone.

Related Articles Pinning across the Metatarsophalangeal Joint for Hammertoe Correction: Where Are We Aiming and What Is the Damage to the Metatarsal Articular Surface? J Foot Ankle Surg. 2013 Jul 18; Authors: Galli MM, Brigido SA, Protzman NM Abstract Kirschner wire (K-wire) fixation across the metatarsophalangeal joint (MTPJ) is commonly used in hammertoe repair surgery. The purpose of the present study was twofold: (1) to determine where the K-wire penetrates the metatarsal articular surface to achieve a rectus digit; and (2) to quantify the percentage of cartilage disruption to better understand the consequences of K-wire transfixation of the MTPJ. Arthrodesis was conducted on the second, third, and fourth proximal interphalangeal joints of 10 below-the-knee cadaver specimens, using a 1.6-mm K-wire. Digital alignment was confirmed with simulated weightbearing intraoperatively and radiographically. The K-wire was removed, and the MTPJ was dissected until the metatarsal head was fully exposed. The penetration point was plotted on a quadrant system with deviation noted from the epicenter. Center was defined as the point equidistant from the medial-to-lateral and superior-to-inferior edges on the distal surface of the metatarsal head, excluding the plantar condyles. Statistically significantly deviations were found in the K-wire placement from the center (35.9% ± 17.5%, p < .001), medial-to-lateral width (22.2% ± 19.2%, p < .001), and dorsal-to-plantar

Related Articles Metastatic Calcaneal Lesion Associated with Uterine Carcinosarcoma. J Foot Ankle Surg. 2013 Jul 18; Authors: Rice BM, Todd NW, Jensen R, Rush SM, Rogers W Abstract Metastatic lesions of uterine carcinosarcoma most commonly occur in the abdomen and lungs and less frequently in highly vascularized bone. We report a rare case of an 86-year-old female with uterine carcinosarcoma with metastasis to the left calcaneus. The patient had a history of uterine carcinosarcoma with hysterectomy and bilateral salpingo-oophorectomy, along with bilateral pelvic and aortic lymphadenectomy, with no adjuvant therapy. The initial pedal complaint was that of left foot pain. The initial radiographic findings were negative; however, magnetic resonance imaging scans revealed a substantial area of marrow edema in the calcaneus. An excisional biopsy was performed, and histopathologic analysis revealed adenocarcinoma with features consistent with the patient's previous uterine tumor specimen. The patient was given one treatment of chemotherapy and was discharged to a hospice, where she died of her disease 2 weeks later.

Related Articles A Useful Surgical Technique for Retrieval of a Broken Guide Pin in the Midfoot. J Foot Ankle Surg. 2013 Jul 18; Authors: Roy SP, Lim CT, Tan KJ Abstract Perioperative instrument breakage is not an infrequent occurrence, even for experienced surgeons. The most commonly reported instrument breaks in orthopedic procedures are drill bits, followed by Kirschner wires and cannulated guide pins. The reasons for failure include improper technique and repetitive use. The retrieval of broken hardware can be technically challenging, particularly if the fragment has become embedded in bone. Retrieval methods have been described for cannulated guide pin fragments in the hip; however, no specific techniques have been described for the retrieval of guide pin fragments embedded in the bones of the foot. In the present report, we describe a technique we have found useful for retrieval of a guide pin fragment that had broken off during a Lisfranc fracture repair 6 weeks earlier. The technique was used in a delayed situation; however, we believe it would be even easier to use during an intraoperative breakage.
