Review
Juvenile hallux valgus is one of the most common pathologies of the forefoot in children and adolescents. Nevertheless, its treatment is still controversial. This deformity has some distinct anatomical features, particularly a lateral tilt of the articular facet of the head of the first metatarsal and congenital metatarsus adductus, which often occur in combination. Some mediocre surgical treatment results can be explained by the lack of correction of all these factors when we approach the problem as we would in adults. A double osteotomy to correct the DMAA and varus of the first metatarsal is a good solution in most cases with satisfactory functional outcomes. A percutaneous approach seems efficient in the pediatric population, given that the periosteum and growth plates, which are very active in younger children, help the osteotomies to heal and remodel. Guided growth surgery - using this approach is a viable alternative in this age bracket. Finally, minimally invasive surgery for juvenile hallux valgus allows another surgery to be done on minimally or undamaged tissues if needed later on.

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).

Review
Iatrogenic hallux varus is formed due to an imbalance between the bone, tendon, and ligamentous-articular structures in the first metatarsophalangeal joint (MJ), with the progression of the medial deviation of the big toe. A secondary factor is an imbalance between excessive medial tension and weakness or excessive soft tissue release of lateral capsular-ligamentous structures. The article is devoted to a rare but no less complex postoperative complication of hallux valgus deformity, acquired hallux varus. Based on the literature data on this topic, in the work, the clinical anatomy of the first metatarsophalangeal joint, the pathogenesis of the development of tendon-muscle imbalance in the above joint, and the leading causes of hallux varus are described. Also, the issues of the clinic, X-ray diagnostics, and classification of this type of foot pathology are considered with a description of the appropriate surgical tactics for different types of deformity.

Review
Iatrogenic hallux varus is a dreaded complication of hallux valgus surgery, consisting in 1st-ray deformity in the form of medial malalignment of the 1st phalanx with respect to the metatarsal axis. Such over-correction results from imbalance between excessive medial capsule retraction or tensioning and excessive lateral laxity or soft-tissue release. There may be loss of medial stability of bone origin due to excessive "exostosectomy" or excessive intermetatarsal angle closure. Following excessive lateral release, the imbalance gradually induces a varus deformity of the 1st phalanx due to traction by the medial muscles: abductor hallucis and medial head of flexor hallucis brevis inserting to the medial sesamoid. The deformity comprises 3 components, of varying importance: medial deviation of the hallux at the 1st metatarsophalangeal joint, supination of the phalanx, and interphalangeal flexion (i.e., claw deformity of the hallux). Treatment strategy is determined by the various clinical and radiological data explaining the postoperative hypercorrection. The clinical analysis is decisive, while radiology contributes more technical factors once the treatment option has been decided on. There are two main options for surgical revision to restore 1st ray propulsion: 1) static or dynamic reconstruction of the ligamentous structures, conserving metatarsophalangeal motion; or 2) metatarsophalangeal and/or interphalangeal fusion. Factors guiding choice are mainly range of motion, and reducibility of the metatarsophalangeal and interphalangeal deformity. We describe the procedures in detail, emphasizing the essential points for success. Joint sparing is to be sought in flexible deformities and young patients. Ligament reconstruction can be anatomic or palliative by tenodesis effect, which makes adjustment difficult. Alongside soft-tissue reconstruction, the metatarsal osteotomy should also be revised if the intermetatarsal angle has been unduly closed. Metatarsophalangeal fusion is the most reliable solution and is unavoidable if the joint is stiff or degenerative; it undoubtedly reduces risk of failure. LEVEL OF EVIDENCE: V, expert opinion.

Review
The research results are inconsistent that assessing whether the increased obliquity of the distal articular surface of the medial cuneiform leads to an increase in hallux valgus angle. Thus, this study investigated the relationship between distal medial cuneiform obliquity and hallux valgus by measuring various angles in weightbearing anteroposterior radiographs of the foot. In total, 679 feet of 538 patients with the radiographs were included in the study. We measured radiographic parameters including hallux valgus angle, first to second intermetatarsal angle, metatarsus adductus angle, first metatarsus cuneiform angle, distal medial cuneiform angle, and first proximal metatarsal articular angle. The surface morphology (flat or curved) of the first tarsometatarsal joint was also recorded. Our results analysis revealed a weak negative correlation between distal medial cuneiform angle and both hallux valgus angle and first to second intermetatarsal angle, contrary to our assumption. So we believe that distal medial cuneiform angle was relatively constant and it cannot be used as a characteristic angle for quantifying hallux valgus. First metatarsus cuneiform angle was a characteristic indicator of hallux valgus and was positively correlated with its severity (p < .000), indicating that it can be used to measure the size of hallux valgus. It can also be used as a reference factor for the first metatarsal osteotomy in clinical bunion orthopedics. First tarsometatarsal joint morphology was unrelated to hallux valgus, whereas metatarsus adductus angle, and first proximal metatarsal articular angle should be considered in hallux valgus.

The aim of the study was to analyze the development of foot structure and the impact of longitudinal and transverse arching of the foot on the position of the hallux and fifth toe in preschool children. The study was carried out among 200 children aged 6 (100 G, 100 B). The research tool was the podoscope CQ-ST. The collected research results were analyzed with the use of the Mann-Whitney U test, Pearson Chi-square test and regression analysis. A statistically significant influence of the heel angle on the value of the varus angle of the fifth toe of the right (girls: = 0.032; boys: = 0.001) and left foot (girls: = 0.004; boys: = 0.005) was found. Boys' feet are longer and wider than girls' feet; moreover, they have a lower longitudinal arch. The frequency of longitudinal and transverse arch deformities of the feet, as well as valgus of the hallux and varus of the fifth toe do not depend on gender. In both sexes, decreasing the transverse arch of the foot has an influence on the severity of varus of the fifth toe. Changes in the height of the longitudinal foot arch does not affect the position of the hallux and fifth toe.

Hallux valgus deformity is a very common pathological condition which commonly produces painful disability. It is characterised as a combined deformity with a malpositioning of the first metatarsophalangeal joint caused by a lateral deviation of the great toe and a medial deviation of the first metatarsal bone.Taking the patient's history and a thorough physical examination are important steps. Anteroposterior and lateral weight-bearing radiographs of the entire foot are crucial for adequate assessment in the treatment of hallux valgus.Non-operative treatment of the hallux valgus cannot correct the deformity. However, insoles and physiotherapy in combination with good footwear can help to control the symptoms.There are many operative techniques for hallux valgus correction. The decision on which surgical technique is used depends on the degree of deformity, the extent of degenerative changes of the first metatarsophalangeal joint and the shape and size of the metatarsal bone and phalangeal deviation. The role of stability of the first tarsometatarsal joint is controversial.Surgical techniques include the modified McBride procedure, distal metatarsal osteotomies, metatarsal shaft osteotomies, the Akin osteotomy, proximal metatarsal osteotomies, the modified Lapidus fusion and the hallux joint fusion. Recently, minimally invasive percutaneous techniques have gained importance and are currently being evaluated more scientifically.Hallux valgus correction is followed by corrective dressings of the great toe post-operatively. Depending on the procedure, partial or full weight-bearing in a post-operative shoe or cast immobilisation is advised. Post-operative radiographs are taken in regular intervals until osseous healing is achieved. Cite this article: Fraissler L, Konrads C, Hoberg M, Rudert M, Walcher M.
