[Treatment of a Progressive Collapsing Foot Deformity]. / Behandlung des Plattfusses.

Treatment of a Progressive Collapsing Foot Deformity Abstract. The so-called "flat foot" can be more accurately described in German as "Knick-Senkfuss" or "kinking-flatfoot". The "kink" refers to the hindfoot axis as such, which can be identified by the intersection of the longitudinal axes of the Achilles tendon and the tuber calcanei. The designation "flat foot" marks the appearance of the longitudinal axis, that is, the medial longitudinal arch, which is easy to determine clinically. Nowadays, a new terminology has been added: Progressive collapsing foot deformity (PCFD). The forms of a PCFD are manifold, as are the possible causes. For this reason, the forms of therapy to be used are often not very simple and must be carefully considered and applied. Not always are PCFD in need of treatment. That means that there are people who have always had such deformities but never develop symptoms. For this reason, only symptomatic patients suffering from a PCFD need treatment. The degree of treatment and its success depends on the careful examination and interpretation of the findings by the orthopedic surgeon. This article deals with treatment of PCFD and attempts to provide a logical overview.

Deformidades de los pies en niños / Foot deformities in children

Las alteraciones en los pies son una consulta frecuente en ortopedia pediátrica. La gran mayoría corresponde a condiciones que no constituyen patología y habitualmente no necesitan tratamiento, como el pie plano flexible. Por otro lado, existen deformidades patológicas que necesitarán un adecuado estudio y tratamiento. Según su morfología podemos clasificarlas en cavo-varo, plano-valgo y misceláneas. Su origen puede ser congénito o adquirido y de diversas etiologías, destacando el pie bot, metatarso varo, hallux valgus juvenil y aquellas secundarias a enfermedades neuromusculares, entre otras. Conocer la historia natural de cada deformidad nos permite decidir el momento más adecuado para cada tratamiento. Los antecedentes mórbidos y perinatales del paciente son muy importantes, así como el nivel de actividad física y/o deportiva. El examen físico debe incluir observar la marcha, extremidades inferiores, tobillo y pie. En el pie se debe analizar cada segmento por separado (antepié, mediopié y retropié) y las articulaciones respectivas. Es muy importante distinguir entre deformidades rígidas y flexibles. El tratamiento incluye la observación (condiciones benignas y autolimitadas), calzado adecuado, insertos plantares, órtesis, yesos correctores, cirugía de partes blandas y cirugía ósea; todo complementado por un adecuado programa de rehabilitación funcional y deportivo.

Foot disorders are a frequent cause of consultation in pediatric orthopaedics. The vast majority correspond to conditions that don't constitute pathology and usually don ́t need treatment, such as flexible flat foot. On the other hand, there are pathological deformities that will require a proper study and treatment. According to their morphology we can classify them in cavo-varus, plano-valgus and miscellaneous. Its origin can be congenital or acquired and due to various etiologies, highlighting clubfoot, metatarsus adductus, juvenile hallux valgus and those secondary to neuromuscular diseases, among others. Knowing the natural history of each deformity allows us to decide the most appropriate time for each treatment. Patient's morbility and perinatal history is very important, as well as their level of physical and/or sports activity. Physical exam should include gait obsevation, lower limbs, ankles and feet. In the foot, each segment should be analyzed separately (forefoot, midfoot and hindfoot) and their joints. It ́s very important to distinguish between rigid and flexible deformities. Treatments include observation (benign and self-limited conditions), adequate footwear, insoles, orthosis, corrective casting, soft tissue surgery and bone surgery; all complemented by an adequate functional and sports rehabilitation programs

The diagnosis and management of common childhood orthopedic disorders: An update.

Musculoskeletal illness represents a significant portion of office visits to primary and urgent care clinicians. Despite this, little emphasis is placed on learning pediatric orthopaedics during medical school or residency. The focus of this paper is to provide a systematic approach to this general musculoskeletal physical exam and to assist in the recognition of what conditions are normal development and what conditions require observation, workup and referral to an experienced pediatric orthopaedist.

The Windswept Foot: Dealing with Metatarsus Adductus and Toe Valgus.

The windswept foot remains a reconstructive challenge. The hallux valgus associated with the medially displaced lesser metatarsal heads is hard to correct. Either the lesser metatarsal heads need to be displaced laterally or the deformity accepted. With the deformity, all the toes tend to be aligned into valgus with the position of the flexor and extensor tendons. Several treatment alternatives exist and may require a combination of open and percutaneous surgery. The authors think that, in severe metatarsus adductus, proximal correction of the first, second, and third metatarsals is required.

Using the Biomechanical Examination to Guide Therapy.

In trying to explain the myriad of foot deformities and symptoms that have slow onset and/or are considered to be overuse syndromes, clinicians have been trying to develop quantitative examinations to describe the cause of the patient's problems and to better individualize treatment modalities. This type of examination is called a biomechanical examination. This article discusses some of the more common portions of a biomechanical examination of the foot and lower extremity. It will also point out some ways that the information from a biomechanical examination can be applied in clinically treating patients.

Pediatric Considerations.

The article discusses the nuances required to effectively perform the biomechanical examination in children and assess the findings. The author covers several factors in children that make the examination different in certain respects than in that of adults, including growth, osseous maturation, gait development, and interpretation of symptoms as conveyed by the child. Further delineation is made for prewalkers, foot-flat to foot-flat walkers, and heel-to-toe walkers. Segmental review of the lower extremity is covered by age bracket, with clinical pearls inserted where relevant to assist the clinician. A brief discussion of shoe wear and orthoses is made as well.

Better wearing comfort of knee-length elastic compression stockings with an interface pressure of 18-21 mmHg compared to 23-32 mmHg in elderly people after a one day trial - Influence on foot deformities, rheumatism and arthritis.

BACKGROUND: Although the efficacy of compression therapy through knee-length compression stockings with an interface pressure of 18-21 mmHg for leg oedemas has been confirmed by many studies, 91% of patients are still treated with a higher interface pressure. METHOD: In this prospective open randomised monocentric study 19 patients (age ≥65, movement restrictions and symptomatic leg oedema) received knee-length compression stockings with an interface pressure of 18-21 mmHg (stocking type 1) and 23-32 mmHg (stocking type 2). On two consecutive days each of the two compression stocking types were worn for at least 8 hours. After this test period, both stocking types were assessed subjectively and skin changes were recorded. RESULT: A significantly (p-value <0.001) subjective improvement of the symptoms and complaints based on leg oedema was reported with the knee-length compression stockings. The Stocking type 1 recorded a significantly (p = 0,045) better wearing comfort. In addition, the Stocking type 2 was significantly too large amongst women in the front foot area (p = 0.044). The most common side effects were constrictions on the proximal lower leg (stocking type 1 = 73,7% (14/19); stocking type 2 = 78,9% (15/19)). Subjects with arthritis (p = 0.006), hallux valgus (p = 0.034) and/or digitus flexus (p = 0.021) found the socking type 1 significantly more comfortable. CONCLUSION: In order to achieve optimal patient compliance it is recommended to prescribe knee-length compression stockings with an interface pressure of 18-21 mmHg if the following criteria are met: age ≥65 years, female sex, arthritis, digitus flexus (claw toe) or hallux valgus.

Treatment of Flexible Lesser Toe Deformities.

Lesser toe deformities are among the most common complaints presented to foot and ankle specialists. These deformities present in variable ways, which makes surgical decision making complex. For every type of deformity, there could be a combination of soft tissues and bony procedures, chosen according to the surgeon's preferences. This article first describes modern classification of lesser toe deformities, and then presents the different treatments and procedures available for those flexible deformities. In addition, this article proposes an algorithm based on clinical/radiological evaluation and step-by-step surgical decision making.

Conservative Management of Metatarsalgia and Lesser Toe Deformities.

There are several forefoot conditions that can result in metatarsal head pain. Various points of the gait cycle can predispose the metatarsal heads to pain based on intrinsic and extrinsic imbalances. Metatarsalgia can further be classified according to primary, secondary, or iatrogenic etiologies. Within these groups, conservative management is the first line of treatment and can often obviate surgical intervention. Depending on the cause of pain, proper shoewear, orthoses, and inserts coupled with targeted physical therapy can alleviate most symptoms of metatarsalgia and lesser toe deformities.

What's New in the Management of Foot Deformities in Children With Cerebral Palsy.

BACKGROUND: Foot deformities have been frequently reported in cerebral palsy (CP), and numerous diagnostic modalities and treatment options have recently been developed to achieve a better level of management for children with CP. METHODS: A thorough search of the English literature, published between January 2013 and March 2016, was performed. A summary of the new findings that had not previously described was reported. The review included recent advances regarding clinical and gait evaluation, orthotic management, botulinum toxin A treatment, and surgical correction. RESULTS: The review summarized new findings reported in 46 articles and abstracts that were published between January 2013 and March 2016. Older articles were included and cited when an original description was mentioned, or when a change or development of some findings was discussed. CONCLUSIONS: Foot deformity forms an essential part of evaluating children with CP. Dramatic advances have been achieved in gait assessment, conservative management, and surgical correction. Promising results have been reported with the goal to reach a higher level of orthopaedic care and optimize the functional potentials for children with CP. LEVEL OF EVIDENCE: Level IV-literature review.

Symptomatic Bipartite Medial Cuneiform: Report of Five Cases and Review of the Literature.

UNLABELLED: Bipartition of the medial cuneiform is a well-described but rarely seen anatomic variant. The majority of literature focuses on anatomic description and incidents based on studies of archeological collections. Symptomatic cases can be overlooked or misdiagnosed initially given the vague complaint of pain either chronic in nature or following an acute injury that could result in a myriad of foot conditions. Treatment ranges from orthotics, immobilization, injection therapy, and surgery. Presented here is a series of 5 cases treated successfully with conservative and surgical measures. LEVELS OF EVIDENCE: Therapeutic, Level IV.

Syndromic Feet: Arthrogryposis and Myelomeningocele.

Treatment of myelomeningocele and arthrogrypotic foot deformities has been controversial; many different procedures have been advocated for each type of deformity. In most cases, outcomes have had variable success rates, and many complications can occur. Treatment strategies should highlight care that avoids the development of a stiffened foot and allows for a variety of options to regain correction when a relapse occurs. This is particularly true in myelomeningocele, whereby a stiff foot runs a high risk for skin ulceration, leading to osteomyelitis. Discussion includes appropriate circumstances for the use of presented procedures and the author's preferred treatment for each deformity.

Cavus Foot.

Cavus foot is usually related to neurologic abnormalities and then requires complete clinical and imaging evaluation. It is important to identify whether the deformity is flexible or rigid, and combine different soft tissue and bony techniques to accomplish the best lasting results. On rigid feet, it is crucial to determine the apex of the deformity to guide the bony procedures indicated for each specific case. Tarsectomies are preferred to arthrodesis in these rigid feet with the aim of achieve a plantigrade foot.

Neuromuscular Foot: Spastic Cerebral Palsy.

Foot and ankle deformities in cerebral palsy can be effectively treated with surgery. Surgery should be considered in patients with significant deformity and those who have pain or difficulty with orthotic and shoe wear. Equinus contracture of both gastrocnemius and soleus can be treated with open tendoachilles lengthening; ankle valgus with medial epiphysiodesis. Equinovarus is more commonly seen in hemiplegic patients and this deformity can usually be treated with tendon transfers. Triple arthrodesis is an option in children with severe degenerative changes. It is important to address all aspects of the child's pathology at the time of surgical correction.

Subtalar coalition in pediatrics.

Subtalar tarsal coalition is an autosomal dominant developmental maldeformation that affects between 2% and 13% of the population. The most common locations are between the calcaneus and navicular and between the talus and calcaneus. If prolonged attempts at nonoperative management do not relieve the pain, surgery is indicated. The exact surgical technique(s) should be based on the location of the pain, the size and histology of the coalition, the health of the other joints and facets, the degree of foot deformity, and the excursion of the heel cord.

Subtalar coalitions in the adult.

Tarsal coalitions, while relatively uncommon, are typically identified in adult patients during an evaluation for ankle instability, sinus tarsus pain, and/or pes planovalgus. The true incidence of tarsal coalition is unknown with estimates ranging from 1% to 12% of the overall population. The most common area of involvement of the subtalar joint is the middle facet, and heightened awareness should be present in adult patients with limited motion of the subtalar joint. Standard radiographic imaging, to include a Harris heel view, is recommended initially, although computerized tomography scan and MRI are often necessary to confirm the diagnosis.

Foot deformities in children with cerebral palsy.

PURPOSE OF REVIEW: The present article describes common foot deformities in children with cerebral palsy and discusses treatment options for each of those deformities. RECENT FINDINGS: Bracing is a useful treatment to correct foot deformities during gait. Surgical correction of foot deformities is typically performed as a part of multilevel single-event gait improvement surgery that has increasingly become the standard of care for ambulatory children with cerebral palsy. Foot realignment may improve knee function during stance, probably because of change of lever arm. SUMMARY: Foot deformities are common among children with cerebral palsy. The three most common among them are equinus, planovalgus and equinovarus/equinocavovarus. Treatment consists of orthotics, physical therapy, spasticity reduction treatment and surgical correction. Guidelines for treatment are individualized and multifactorial. Important considerations include the child's level of function, the severity and flexibility of the deformity, the presence or absence of pain and skin irritation, and the changes in alignment observed over time.

Pes planovalgus deformity in children with cerebral palsy: review article.

Pes planovalgus deformity is common in children with cerebral palsy. In planovalgus foot, the talus subluxates medially, the calcaneus is in valgus, and the forefoot is in supination and external rotation related to the midfoot. In young children, mild planovalgus feet can be managed with orthotics. Surgery is indicated if the deformity is not reducible or if the patient cannot tolerate orthotics during functional activities. The surgery can be calcaneal lengthening or subtalar fusion to restore a stable plantigrade foot and achieve hindfoot correction. Medial column fusion is important to reconstruct the medial arch in severe planovalgus feet.
