[Ab] Resumo:AIMS: Fractures of the navicular can occur in isolation but, owing to the intimate anatomical and biomechanical relationships, are often associated with other injuries to the neighbouring bones and joints in the foot. As a result, they can lead to long-term morbidity and poor function. Our aim in this study was to identify patterns of injury in a new classification system of traumatic fractures of the navicular, with consideration being given to the commonly associated injuries to the midfoot. PATIENTS AND METHODS: We undertook a retrospective review of 285 consecutive patients presenting over an eight- year period with a fracture of the navicular. Five common patterns of injury were identified and classified according to the radiological features. Type 1 fractures are dorsal avulsion injuries related to the capsule of the talonavicular joint. Type 2 fractures are isolated avulsion injuries to the tuberosity of the navicular. Type 3 fractures are a variant of tarsometatarsal fracture/dislocations creating instability of the medial ray. Type 4 fractures involve the body of the navicular with no associated injury to the lateral column and type 5 fractures occur in conjunction with disruption of the midtarsal joint with crushing of the medial or lateral, or both, columns of the foot. RESULTS: In order to test the reliability and reproducibility of this new classification, a cohort of 30 patients with a fracture of the navicular were classified by six independent assessors at two separate times, six months apart. Interobserver reliability and intraobserver reproducibility both had substantial agreement, with kappa values of 0.80 and 0.72, respectively. CONCLUSION: We propose a logical, all-inclusive, and mutually exclusive classification system for fractures of the navicular that gives associated injuries involving the lateral column due consideration. We have shown that this system is reliable and reproducible and have described the rationale for the subsequent treatment of each type. Cite this article: 2018;100-B:176-82.

[Ti] Título:A Finite Element Model of the Foot/Ankle to Evaluate Injury Risk in Various Postures.

[Ab] Resumo:The foot/ankle complex is frequently injured in many types of debilitating events, such as car crashes. Numerical models used to assess injury risk are typically minimally validated and do not account for ankle posture variations that frequently occur during these events. The purpose of this study was to evaluate a finite element model of the foot and ankle accounting for these positional changes. A model was constructed from computed tomography scans of a male cadaveric lower leg and was evaluated by comparing simulated bone positions and strain responses to experimental results at five postures in which fractures are commonly reported. The bone positions showed agreement typically within 6° or less in all anatomical directions, and strain matching was consistent with the range of errors observed in similar studies (typically within 50% of the average strains). Fracture thresholds and locations in each posture were also estimated to be similar to those reported in the literature (ranging from 6.3 kN in the neutral posture to 3.9 kN in combined eversion and external rotation). The least vulnerable posture was neutral, and all other postures had lower fracture thresholds, indicating that examination of the fracture threshold of the lower limb in the neutral posture alone may be an underestimation. This work presents an important step forward in the modeling of lower limb injury risk in altered ankle postures. Potential clinical applications of the model include the development of postural guidelines to minimize injury, as well as the evaluation of new protective systems.

[Ab] Resumo:Aneurysmal bone cysts (ABC) are rare and they represent 1- 1.4 % of all primary bone tumors. ABC of cuboid bone are extremely rare, especially in children. Very few cases have been reported in the literature since 1967. We present a case of pathological fracture of cuboid bone due to an aneurysmal cyst in a 10-year-old girl. Surgery was performed, which included open biopsy with aspiration and intralesional curettage . Bone defect was then filled in by fully synthetic cancellous bone graft substitute consisting of pure ß-tricalcium phosphate. Aneurysmal cyst of cuboid bone with pathological fracture could be successfully treated with pure ß-tricalcium phosphate as a bone graft substitute. This procedure is safe with excellent outcome.Follow up to nearly four years did not show any recurrence.

[Ab] Resumo:Kohler's disease is rare cause of foot pain and limping in the pediatric population. The exact etiology of Kohler's disease is unknown. It usually presents as sudden and unexplained foot pain and limping. We report a case of a 5-year-old male who presented to the Pediatric Emergency Department with foot pain and inability to bear weight for two days after overactivity and acute foot injury. The patient was eventually diagnosed with Kohler's disease (avascular necrosis of the navicular bone). Although Kohler's disease is not very common, it should be considered in the differential diagnosis of foot pain in the pediatric population, as it may prevent unnecessary tests and treatments.

[Ti] Título:Quantification of the ossification of the lateral cuneiform in the feet of young children with unilateral congenital talipes equinovarus.

[La] Idioma:eng
[Ab] Resumo:AIMS: After the initial correction of congenital talipes equinovarus (CTEV) using the Ponseti method, a subsequent dynamic deformity is often managed by transfer of the tendon of tibialis anterior (TATT) to the lateral cuneiform. Many surgeons believe the lateral cuneiform should be ossified before surgery is undertaken. This study quantifies the ossification process of the lateral cuneiform in children with CTEV between one and three years of age. PATIENTS AND METHODS: The length, width and height of the lateral cuneiform were measured in 43 consecutive patients with unilateral CTEV who had been treated using the Ponseti method. Measurements were taken by two independent observers on standardised anteroposterior and lateral radiographs of both feet taken at one, two and three years of age. RESULTS: All dimensions of the lateral cuneiform on the affected side increased annually but remained smaller than the corresponding dimensions of the unaffected foot (p < 0.01). The lateral cuneiform resembled a 9 mm cube at two years and an 11 mm cube at three years. CONCLUSION: At one and two years, the ossification centre of the lateral cuneiform may not be large enough to accommodate a drill hole for tendon transfer. However, by three years, it has undergone sufficient ossification to do so. Cite this article: 2017;99-B:1109-14.

[Ti] Título:Vascularized Pedicle Bone-Grafting from the Cuboid for Talar Osteonecrosis: Results of a Novel Salvage Procedure.
[So] Source:J Bone Joint Surg Am;99(10):848-854, 2017 May 17.

[Ab] Resumo:BACKGROUND: Osteonecrosis of the talar body represents a complex clinical challenge with treatment options currently limited to core decompression, vascularized and nonvascularized bone-grafting, total talar replacement, and hindfoot arthrodesis. Vascularized pedicle bone-grafting from the cuboid to the talus is a potential alternative to contemporary operative options for replacement of necrotic talar tissue with viable bone. We aimed to analyze functional and radiographic outcomes of vascularized pedicle bone-grafting from the cuboid for the treatment of talar osteonecrosis in a consecutive series of patients spanning a 12-year period. METHODS: Patients with osteonecrosis of the talar body and dome who underwent vascularized pedicle bone-grafting from the cuboid to the talus at our institution between 2003 and 2014 were retrospectively identified. All patients had preoperative radiographs and magnetic resonance imaging (MRI) scans and were monitored postoperatively with serial radiographs and MRI. For generic health-related quality-of-life (HRQoL) assessment, patients were given the preoperative Medical Outcomes Study Short Form-12 (SF-12) and postoperative 36-Item Short Form (SF-36) from which Physical Component Summary (PCS) and Mental Component Summary (MCS) scores were derived and compared before and after surgery. RESULTS: Thirteen patients were identified and sequentially followed for 2 to 12 years (mean, 6 years). Two patients had failure of treatment and subsequently underwent total ankle replacement, 1 patient had arthroscopic debridement for soft-tissue impingement, and no other patient required secondary surgery. The average PCS score (and standard deviation) significantly improved by 23.3 ± 18.9 points with surgery (p = 0.006), and the average MCS score significantly increased by 39.4 ± 10.1 points (p < 0.001). CONCLUSIONS: HRQoL outcomes suggest that vascularized pedicle bone-grafting from the cuboid combined with bracing for 1 year may be a viable treatment option for osteonecrosis of the talus that provides good pain relief and improved physical function without necessitating a secondary procedure for the majority of patients. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

[Ti] Título:Optimal Starting Point for Fifth Metatarsal Zone II Fractures: A Cadaveric Study.
[So] Source:Foot Ankle Int;38(7):802-807, 2017 Jul.
[Is] ISSN:1944-7876

[Ab] Resumo:BACKGROUND: Identifying the optimal starting point for intramedullary fixation of tibia and femur fractures is well described in the literature using a retrograde or anterograde technique. This technique has not been applied to the fifth metatarsal, where screw trajectory can cause iatrogenic malreduction. The generally accepted starting point for the fifth metatarsal is "high and inside" to accommodate the fifth metatarsal's dorsal apex and medial curvature. We used a retrograde technique to identify the optimal starting position for intramedullary fixation of fifth metatarsal fractures. METHODS: Five matched cadaveric lower extremity pairs were dissected to the fifth metatarsal neck. An osteotomy was made to access the intramedullary canal. A retrograde reamer was passed to the base of the fifth metatarsal to ascertain the ideal entry point. Distances from each major structure on the lateral aspect of the foot were measured. Computed tomography scans helped assess base edge measurements. RESULTS: In 6 of 10 specimens, the retrograde reamer hit the cuboid with a cuboid invasion averaging 0.7 mm. The peroneus brevis and longus were closest to the starting position with an average distance of 5.1 mm and 5.7 mm, respectively. Distances from the entry point to the dorsal, plantar, medial, and lateral edges of the metatarsal base were 8.3 mm, 6.9 mm, 9.7 mm, and 9.7 mm, respectively. CONCLUSION: Optimal starting position was found to be essentially at the center of the base of the fifth metatarsal at the lateral margin of the cartilage. Osteoplasty of the cuboid or forefoot adduction may be required to gain access to this site. CLINICAL RELEVANCE: This study evaluated the ideal starting position for screw placement of zone II base of the fifth metatarsal fractures, which should be considered when performing internal fixation for these fractures.

[Ti] Título:The tarsal-metatarsal complex of caviomorph rodents: Anatomy and functional-adaptive analysis.

[Ab] Resumo:Caviomorph rodents represent a major adaptive radiation of Neotropical mammals. They occupy a variety of ecological niches, which is also reflected in their wide array of locomotor behaviors. It is expected that this radiation would be mirrored by an equivalent disparity of tarsal-metatarsal morphology. Here, the tarsal-metatarsal complex of Erethizontidae, Cuniculidae, Dasyproctidae, Caviidae, Chinchillidae, Octodontidae, Ctenomyidae, and Echimyidae was examined, in order to evaluate its anatomical variation and functional-adaptive relevance in relation to locomotor behaviors. A qualitative study in functional morphology and a geometric morphometric analysis were performed. We recognized two distinct tarsal-metatarsal patterns that represent the extremes of anatomical variation in the foot. The first, typically present in arboreal species, is characterized by features that facilitate movements at different levels of the tarsal-metatarsal complex. The second pattern, typically present in cursorial caviomorphs, has a set of features that act to stabilize the joints, improve the interlocking of the tarsal bones, and restrict movements to the parasagittal plane. The morphological disparity recognized in this study seems to result from specific locomotor adaptations to climb, dig, run, jump and swim, as well as phylogenetic effects within and among the groups studies.

[Ab] Resumo:OBJECTIVE: Our objective is to review the anatomy and exposure of the posterior column and posterior tibial malleolus (the posterior tibial plafond) by defining the access corridors through 3 different approaches-posteromedial, posterolateral, and modified posteromedial. METHODS: Cadaveric dissection with percentage of posterior tibial malleolus exposed, and strain gauge measurements to evaluate traction on the neurovascular bundle. RESULTS: The 3 different approaches are applicable for exposure of different portions of the distal posterior tibial malleolus. Strain gauge measurements reveal the least traction on the flap containing the neurovascular bundle with the modified posteromedial approach (7.0 N) compared with the posteromedial (21.5 N) and posterolateral (16.8 N) approaches. Exposure of the posterior tibial malleolus was greater with the modified posteromedial approach (91%) compared with the other 2 approaches (posteromedial = 64%, posterolateral = 40%). CONCLUSIONS: Depending on the location of the principal fracture fragments, particularly in high energy ankle and pilon fractures, each of the posterior approaches has its indication, with the modified posteromedial approach revealing more of the posterior anatomy than the other 2 approaches. The latter approach places the least traction on the flap containing the neurovascular bundle.

[Ti] Título:Computed tomography derived bone density measurement in the diabetic foot.

[La] Idioma:eng
[Ab] Resumo:BACKGROUND: The accurate and reliable measurement of foot bone density is challenging and there is currently no gold standard technique. Such measurement is particularly valuable in populations at risk of foot bone pathology such as in those with long term diabetes. With research and development, computed tomography may prove to be a useful tool for this assessment. The aim of this study was to establish the reliability of a novel method of foot bone density measurement in people with diabetes using computed tomography. METHODS: Ten feet in people with diabetes were scanned with computed tomography twice with repositioning. Bone density (in Hounsfield units) was assessed in the trabecular and cortical bone in all tarsals and metatarsals. Reliability was assessed with intra-class correlation coefficients (95% confidence intervals), limits of agreement and standard error of measurement. RESULTS: The reliability of the trabecular density of most bones was excellent with intra-class correlation coefficients ranging from 0.68 to 0.91. Additionally, cortical bone density showed fair to good reliability at the talus (0.52), calcaneus (0.59), navicular (0.70), cuboid (0.69), intermediate cuneiform (0.46) and first metatarsal (0.61). CONCLUSIONS: The study established the reliability of a practical method of assessing the trabecular and cortical foot bone density using computed tomography scanning. This methodology may be useful in the investigation of foot bone disease occurring in diabetes and its early diagnosis, intervention and assessment of treatment efficacy. Further development of this method is warranted.
