Review
The causes of metatarsalgia are classified as primary, secondary, and iatrogenic. Anatomical and biomechanical considerations separate "static" from "propulsive" forms of metatarsalgia. The physical examination should be combined with an assessment of weight-bearing radiographs and, if needed, of ultrasound or magnetic resonance imaging scans. The first-line treatment is conservative (stretching exercises, footwear modification, insoles, and lesion debridement). Soft-tissue surgical procedures (gastrocnemius muscle recession, tendon transfer, and plantar plate repair) should also be considered. Among the various types of metatarsal osteotomy, the Weil procedure is reliable. Percutaneous methods are being developed but require evaluation. A treatment algorithm can be developed based on whether the hallux is normal or abnormal. Metatarsalgia due to inflammatory disease requires a specific treatment strategy.

Review
Congenital pathologies of the forefoot encompass two broad entities with vastly different treatments and prognosis: malformations, which occur during the embryonic period and cause anatomical defects, and deformations, which occur during the fetal period on a foot that is configured normally. These deformities are more easily cured when they occur later during the fetal period. When the anomaly is bilateral, a genetic origin must be considered. There are two main entities under the term "deformity": metatarsus adductus and skewfoot (aka "Z"-foot or serpentine foot). Within malformations are brachydactyly (transverse defects), longitudinal defects, syndactyly, polydactyly, clinodactyly and macrodactyly. Among other forefoot abnormalities are hallux valgus, which rarely presents in congenital form, and for which conservative treatment is sometimes sufficient. Also in this group are sequelae of amniotic band constriction, forefoot anomalies secondary to the treatment of congenital pathologies (talipes equinovarus and congenital vertical talus) and nail-related pathologies (ingrown toe nail and incorrect nail position).

BACKGROUND
Metatarsal fractures are among the most common foot and ankle injuries, with an annual incidence of 6.7 per 100 000 persons. Approximately 30% of metatarsal fractures affect the base of the fifth metatarsal bone. Nevertheless, no evidence-based treatment recommendations are available to date.
METHODS
The three fracture localizations according to Lawrence and Botte (zone I, proximal to the intermetatarsal joint between the fourth and fifth metatarsal bones; zone II, in the area of the joint; zone III, at the distal end of the joint) are analyzed on the basis of a systematic literature search. Studies were included that compared the treatment of two types of fracture in the same manner, or that compared two different treatments for a single type of fracture.
RESULTS
Nine studies compared different treatments of zone I fractures. Two of these were randomized controlled trials (RCTs); in one RCT, patients given functional therapy returned to work much sooner than those treated with immobilization (11 vs. 28 days; p = 0.001), with otherwise similar outcomes. The non-randomized studies revealed a faster return to full function (33 vs. 46 days; p<0.05) with early functional therapy, and similar outcomes for immobilization and surgery. One RCT that compared functional therapy with immobilization for zone II fractures revealed no statistically significant difference. Five studies compared fractures in zones I and II that were treated in the same manner, revealing similar outcomes. One RCT compared surgery and immobilization for zone III fractures: surgery led to statistically significant improvement of the outcome in all of the measured parameters.
CONCLUSION
Fractures in zones I and II should be treated with early functional therapy. There seems to be no reason to consider zone I and II fractures as two separate entities, as the outcomes in the two groups are similar. In contrast, fractures in zone III should primarily be treated surgically.

Review
INTRODUCTION
Bunions are prominent and often inflamed metatarsal heads and overlying bursae, usually associated with hallux valgus where the great toe moves towards the second toe. Hallux valgus is found in at least 2% of children aged 9-10 years, and almost half of adults, with greater prevalence in women.
METHODS AND OUTCOMES
We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of conservative treatments, surgery, and postoperative care for bunions? We searched: Medline, Embase, The Cochrane Library, and other important databases up to May 2008 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).
RESULTS
We found 21 systematic reviews, RCTs, or observational studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.
CONCLUSIONS
In this systematic review, we present information relating to the effectiveness and safety of the following interventions: arthrodesis (Lapidus procedure); bone fixation (absorbable pin fixation, screw fixation plus early weight-bearing, standard fixation, suture fixation plus delayed weight-bearing, percutaneous Kirschner-wire fixation); chevron osteotomy plus adductor tenotomy; distal metatarsal osteotomy; early weight-bearing; Keller's arthroplasty; Keller-Lelievre arthroplasty; night splints; orthoses (including antipronatory orthoses in children); phalangeal (Akin) osteotomy plus distal chevron osteotomy; proximal osteotomy, and slipper casts.

Review
Central metatarsal fractures (CMF) are common injuries. More frequently fractures are those of the fifth metatarsal, followed by CMF and therefore by the first metatarsal. Third metatarsal is injured most frequently than the others and up to 63% is associated with second or fourth metatarsal fractures and up to 28% with both. Anatomy and metatarsal kinematics merits attention due to its influence on function, injuries and treatment options. Diagnosis is based on the history of trauma and clinical examination, relating with instrumental exams. Fractures with less than 10° of angulation and 3-4 mm of translation in any plane are typically treated conservatively, while operative treatment is generally reserved for fractures out if these values. Intramedullary fixation with K-wires seem to be the most common and valid surgical treatment in simple fractures. Spiral fractures should be treated by interfragmentary screws, which positioning may result difficult due to the adjacent metatarsals. Therefore, an alternative approach is an osteosynthesis with a dorsal plate. Multiple metatarsal fractures often occur in the contiguous bones, so clinicians will also have to carefully inspect metatarsals and adjacent joints such as Lisfranc articulation. The clinical and functional outcomes are often influenced by the pattern of fractures and patient conditions and are reported in the literature up to 39% of poor results.

Review
Hallux valgus deformity is a multiplanar deformity, where the rotational component has been recognized over the past 5 to 10 years and given considerable importance. Years ago, a rounded shape of the lateral edge of the first metatarsal head was identified as an important factor to detect after surgery because a less rounded metatarsal head was associated to less recurrence. More recently, pronation of the metatarsal bone was identified as the cause for the rounded appearance of the metatarsal head, and therefore, supination stress was found to be useful to achieve a better correction of the deformity. Using CT scans, up to 87% of hallux valgus cases have been shown to present with a pronated metatarsal bone, which highlights the multiplanar nature of the deformity. This pronation explained the perceived shape of the metatarsal bone and the malposition of the medial sesamoid bone in radiological studies, which has been associated as one of the most important factors for recurrence after treatment. Treatment options are discussed briefly, including metatarsal osteotomies and tarsometatarsal arthrodesis.

Bone lengthening and bone transport are regeneration processes that commonly rely on distraction osteogenesis, a widely accepted surgical procedure to deal with numerous bony pathologies. Despite the extensive study in the literature of the influence of biomechanical factors, a lack of knowledge about their mechanobiological differences prevents a clinical particularization. Bone lengthening treatments were performed on sheep metatarsus by reproducing the surgical and biomechanical protocol of previous bone transport experiments. Several in vivo monitoring techniques were employed to build an exhaustive comparison: gait analysis, radiographic and CT assessment, force measures through the fixation, or mechanical characterization of the new tissue. A significant initial loss of the bearing capacity, quantified by the ground reaction forces and the limb contact time with the ground, is suffered by the bone lengthening specimens. The potential effects of this anomaly on the musculoskeletal force distribution and the evolution of the bone callus elastic modulus over time are also analyzed. Imaging techniques also seem to reveal lower bone volume in the bone lengthening callus than in the bone transport one, but an equivalent mineralization rate. The simultaneous quantification of biological and mechanical parameters provides valuable information for the daily clinical routine and numerical tools development.

BACKGROUND
This study aimed to measure the length of metacarpal and metatarsal bones in five Iranian sheep breeds and to correlate the length of the bones with ungula measurements. Thoracic and pelvic limbs of 2-year-old, previously untrimmed, pastured Afshari, Moghani, Kurdi, Makoui, and Lori-Bakhtiari ewes, (n = 20 ewes per breed) were collected after slaughter. The following lengths were recorded in the metacarpal and metatarsal bones: from the margo proximalis lateralis to the lateral (L1) and medial (D1) cartilago physialis; from the margo proximalis lateralis to the margo abaxialis of the lateral (L2) and medial (D2) caput; from the cartilago physialis lateralis to the margo abaxialis of the lateral caput (X1); from the cartilago physialis medialis to the margo distalis of the caput ridge (X2) and from the margo axialis of cartilago physialis to the margo axialis of the lateral caput (X3). Additionally, measurements of the ungula including pars dorsalis length, pars mobilis lateralis and medialis height, pars dorsalis height to the ground and to the solea cornea, thickness of the solea in the pars dorsalis, pars mobilis lateralis and medialis, solea cornea length and angulus dorsalis were recorded in the medial and lateral digits of the thoracic and pelvic limbs. Data on length of the metatarsal and metacarpal bones were analysed using mixed model equations while Pearson correlations were calculated between metacarpal and metatarsal bones and ungula measurements.
RESULTS
Lori- Bakhtiari and Moghani ewes had greater L1, L2, and D1 and D2 while X1, X2 and X3 was greater in Kurdi ewes (P < 0.05). Measurements such as L1, L2, D1 and D2 were greater in the metatarsal than in metacarpal bones (P < 0.05) and the opposite was observed for X1, X2 and X3 (P < 0.05). No asymmetry was observed between the lateral and medial measurements (P > 0.05). Low to moderate correlations were observed between bone and ungula measurements (P < 0.05).
CONCLUSION
Under the conditions of this study, differences in metacarpal and metatarsal bone measurements were observed between breeds but no asymmetry was observed between lateral and medial bones. Results indicate an association between metacarpal and metatarsal bones ungula measurements. This could provide baseline information for the development and/or improvement of current ungula health protocols in the studied sheep breeds.

Review
BACKGROUND
The term "floating" is used in orthopedic literature to describe certain patterns of skeletal injuries that share one common character which is disruption and discontinuity of bones above and below a joint. The first time used in orthopedic literature being in late 1970 to describe a type of elbow injury. Later the word was used increasingly and applied to a variety of injuries affecting the knee, shoulder, hip, forearm, hand, and ankle. Currently, there are about 12 different skeletal injuries described as floating.
OBJECTIVES
The aim of this article was to define the term "floating" used in traumatic orthopedics and to discuss its history, mechanism of injury in each region, treatment and outcomes based on the currently available literature. As there were many separate articles describing different sites of floating injuries, this review aimed to summarize all floating injuries into 1 article.

BACKGROUND
In people with diabetes (DM) and peripheral neuropathy (PN), loss of bone mineral density (BMD) in the tarsals and metatarsals contribute to foot complications; however, changes in BMD of the calcaneal bone is most commonly reported. This study reports rate of change in BMD of all the individual bones in the foot, in participants with DM and PN. Our aim was to investigate whether the rate of BMD change is similar across all the bones of the foot.
METHODS
Participants with DM and PN (n = 60) were included in this longitudinal cohort study. Rate of BMD change of individual bones was monitored using computed tomography at baseline and 6 months, 18 months, and 3-4 years from baseline. Personal factors (age, sex, medication use, step count, sedentary time, and PN severity) were assessed. A random coefficient model estimated rate of change of BMD in all bones and Pearson correlation tested relationships between personal factor variables and rate of BMD change.
RESULTS
Mean and calcaneal BMD decreased over the study period (p < 0.05). Individual tarsal and metatarsal bones present a range of rate of BMD change (-0.3 to -0.9%/year) but were not significantly different than calcaneal BMD change. Only age showed significant correlation with BMD and rate of BMD change.
CONCLUSION
The rate of BMD change did not significantly differ across different foot bones at the group level in people with DM and PN without foot deformity. Asymmetric BMD loss between individual bones of the foot and aging may be indicators of pathologic changes and require further investigation.
