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.

Related Articles Ultrasound Imaging for Diagnosis of Plantar Plate Ruptures of the Lesser Metatarsophalangeal Joints: A Retrospective Case Series. J Foot Ankle Surg. 2013 Jul 16; Authors: Carlson RM, Dux K, Stuck RM Abstract Tears of the plantar plate can be a source of significant forefoot pain, leading to alterations of foot function and gait. The objective of the present retrospective study was to further determine the value of ultrasound imaging in diagnosing plantar plate tears after clinical evaluation through a comparison of the ultrasound and intraoperative examination findings. Eight patients were identified who had undergone surgical intervention for a painful lesser metatarsophalangeal joint after ultrasound examination to diagnose a plantar plate pathologic entity. The intraoperative examination findings were used to calculate the sensitivity, specificity, and positive and negative predictive values of ultrasound in the diagnosis of plantar plate tears. The sensitivity and specificity of the ultrasound examination was 1 and 0.6, respectively. The positive and negative predictive value was 0.6 and 1, respectively. An ultrasound examination in the diagnosis of lesser metatarsophalangeal joint plantar plate tears displayed comparable sensitivity in identifying the pathologic features when compared with magnetic resonance imaging, with considerably less financial cost for the examination.

Related Articles Quantitative assessment of the yield of osteoblastic connective tissue progenitors in bone marrow aspirate from the iliac crest, tibia, and calcaneus. J Bone Joint Surg Am. 2013 Jul 17;95(14):1312-6 Authors: Hyer CF, Berlet GC, Bussewitz BW, Hankins T, Ziegler HL, Philbin TM Abstract BACKGROUND: It is well known that bone marrow aspirate from the iliac crest contains osteoblastic connective tissue progenitor cells. Alternative harvest sites in foot and ankle surgery include the distal aspect of the tibia and the calcaneus. To our knowledge, no previous studies have characterized the quality of bone marrow aspirate obtained from these alternative sites and compared the results with those of aspirate from the iliac crest. The goal of this study was to determine which anatomic location yields the highest number of osteoblastic progenitor cells. METHODS: Forty patients were prospectively enrolled in the study, and separate bone marrow aspirate samples were harvested from the ipsilateral anterior iliac crest, distal tibial metaphysis, and calcaneal body. The aspirate was centrifuged to obtain a concentrate of nucleated cells, which were plated and grown in cell culture. Colonies that stained positive for alkaline phosphatase were counted to estimate the number of osteoblastic progenitor cells in the initial sample. The anatomic locations were compared. Clinical parameters (including sex, age, tobacco use, body mass index, and diabetes) were assessed as

Related Articles Proximal Oblique Sliding Closing Wedge Osteotomy for Hallux Valgus. Foot Ankle Int. 2013 Jul 17; Authors: Wagner E, Ortiz C, Gould JS, Naranje S, Wagner P, Mococain P, Keller A, Valderrama JJ, Espinosa M Abstract BACKGROUND: The proximal oblique sliding closing wedge osteotomy (POSCOW) technique was developed to address moderate to severe hallux valgus deformity. We present a retrospective multicenter study to analyze the midterm radiological and clinical outcomes of patients treated with this type of proximal osteotomy fixed with plates. MATERIALS AND METHODS: One hundred and forty-four patients (187 feet) were operated on between May 2005 and June 2010 in 2 separate centers. Inclusion criteria were symptomatic moderate to severe incongruent hallux valgus deformity, no significant restriction in the first metatarsophalangeal joint movement, none to minimal degenerative changes in the first metatarsophalangeal or the tarsometatarsal joints, and no hypermobility. The median age was 60 years. The preoperative hallux valgus angle (HV) was 35.6 degrees, intermetatarsal angle (IM) was 15.3 degrees, AOFAS score was 53 points. The median follow-up was 35 months (range, 12-73). A POSCOW osteotomy was performed in all patients and fixed with plates. We recorded the satisfaction rate, postoperative clinical and radiological results, and complications.

Related Articles Glomus Tumor of the Great Toe. J Foot Ankle Surg. 2013 Jul 13; Authors: Lui TH, Mak SM Abstract Glomus tumor is a rare mesenchymal neoplasm composed of cells that resemble the modified perivascular smooth muscle cells (glomus cells) of the normal glomus body. A glomus tumor can appear in any part of the body, although it mostly appears in the extremities, especially in the subungual area of the hand. It has been less commonly reported in the foot. A case of glomus tumor of the pulp of the hallux is described in the present report.
