Osseous Healing in Foot and Ankle Surgery with Autograft, Allograft, and Other Orthobiologics.

In the surgical treatment of foot and ankle abnormality, many problems require bone grafting for successful osseous union. Nonunion, reconstruction, and arthrodesis procedures pose specific challenges due to bony defects secondary to trauma, malunions, or previous surgery. Nonunion in foot and ankle arthrodesis is a significant risk and is well documented in recent literature. This article is a review of the recent literature regarding the use of bone graft and orthobiologics in foot and ankle surgery.

Foot and ankle problems in Muay Thai kickboxers.

BACKGROUND: Muay Thai kickboxing is a common sport that uses the foot and ankle in fighting. Muay Thai kickboxing trainees usually receive training in Thailand Foot and ankle problems in this group ofpeople who usually train barefoot remain unexplored OBJECTIVE: To evaluate the prevalence of common foot and ankle problems in Muay Thai kick boxers. MATERIAL AND METHOD: The present study is a cross-sectional survey of Muay Thai kick boxers practicing in northern Thailand. Interviews were conducted and foot and ankle examinations were evaluated Foot morphology was examined using a Harris mat footprint. RESULTS: One hundred and twenty-three Muay Thai kickbox ersinnine training gyms were included in this study. Common foot and ankle problems found in the Muay Thai kick boxers were callosity (59%), gastrocnemius contracture (57%), toe deformities (49.3%), wounds (10%) and heel pain (9%). Callosity was most commonly found on the forefoot (77.5%), on the plantar first metatarsal (55.3%) and on the big toe (33.3%). An association was found between a tight heel cord and a history of foot injury with prolonged periods of weekly training. Toe deformities such as hallux rigidus (37.6%) were also associated with prolonged periods of training (p = 0.001). No correlation was found between type of foot arch and foot and ankle problems. CONCLUSION: Plantar forefoot callosities and wounds as well as toe deformities including tight heel cords are some of the foot and ankle problems commonly found in Muay Thai kick boxers. They are associated with prolonged periods of barefoot training. The unique pattern of training and of the kicks in Muay Thai might be a path mechanism, leading to the development of foot and ankle problems.

Femoral bone transport by a monolateral external fixator with or without the use of intramedullary nail: a single-department retrospective study.

BACKGROUNDS: Treatment for bone defect remains a challenge for orthopedists. Bone transport gives an effective alternative, which can be performed with an external fixator alone or combined with an intramedullary nail. Each has its advantages and disadvantages. We present a retrospective study to find out the optimal choice by evaluating the outcomes of treatment for femoral bone defect with two methods. METHODS: Two groups of patients, the monolateral external fixator alone (group A, n = 13) and the monolateral external fixator combined with intramedullary nail (group B, n = 15), were compared. Duration of the external fixator, external fixator index, radiographic consolidation index, complication, and total cost for treatment was also recorded. A modified classification of the Association for the Study and Application of the Method of Ilizarov (ASAMI) was used to assess results in two groups of patients; another SF-36 health survey questionnaire was used to assess the life qualities patients of two groups. RESULTS: Healing was achieved in 13/13 and 13/15 of the two groups, respectively. The rates of complications were significantly higher in the group A. Two patients performed amputations because of persistent deep infections in group B. Statistically significant difference was found when comparing ASAMI scores and categories of the SF-36 health survey. CONCLUSIONS: Bone transport by monolateral external fixator with the use of intramedullary nail reduces the incidence of complication and the duration of external fixator time that give patients a better life quality in both physical and emotional. However, if chronic osteitis exists, bone transport should be treated with monolateral external fixator alone due to a lower rate of amputations.

[Footwear according to the "business dress code", and the health condition of women's feet--computer-assisted holistic evaluation]. / Obuwie zgodne z "business dress code" a kondycja zdrowotna stóp kobiet--komputerowo wspomagana ocena holistyczna.

BACKGROUND: According to the verdict of the Supreme Court in 2005, an employer may dismiss an employee if their conduct (including dress) exposes the employer to losses or threatens his interests. The aim of the study was a holistic assessment of the pleiotropic effects of high-heeled pointed shoes on the health condition of women's feet, wearing them at work, in accordance with the existing rules of the "business dress code". MATERIALS AND METHODS: A holistic multidisciplinary analysis was performed. It takes into account: 1) women employees of banks and other large corporations (82 persons); 2) 2D FEM computer model developed by the authors of foot deformed by pointed high-heeled shoes; 3) web site found after entering the code "business dress code". RESULTS: Over 60% of women in the office wore high-heeled shoes. The following has been found among people walking to work in high heels: 1) reduction in the quality of life in about 70% of cases, through periodic occurrence of pain and reduction of functional capacity of the feet; 2) increase in the pressure on the plantar side of the forefoot at least twice; 3) the continued effects the forces deforming the forefoot. CONCLUSIONS: 1. An evolutionary change of "dress code" shoes is necessary in order to lead to a reduction in non-physiological overload of feet and the consequence of their disability. 2. These changes are particularly urgent in patients with so-called "sensitive foot".

The use of the analytic hierarchy process to aid decision making in acquired equinovarus deformity.

OBJECTIVE: To increase the transparency of decision making about treatment in patients with equinovarus deformity poststroke. DESIGN: The analytic hierarchy process (AHP) was used as a structured methodology to study the subjective rationale behind choice of treatment. SETTING: An 8-hour meeting at a centrally located rehabilitation center in The Netherlands, during which a patient video was shown to all participants (using a personal computer and a large screen) and the patient details were provided on paper. PARTICIPANTS: A panel of 10 health professionals from different backgrounds. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: The performance of the applicable treatments on outcome, impact, comfort, cosmetics, daily effort, and risks and side effects of treatment, as well as the relative importance of criteria in the choice of treatment. RESULTS: According to the model, soft-tissue surgery (.413) ranked first as the preferred treatment, followed by orthopedic footwear (.181), ankle-foot orthosis (.147), surface electrostimulation (.137), and finally implanted electrostimulation (.123). Outcome was the most influential consideration affecting treatment choice (.509), followed by risk and side effects (.194), comfort (.104), daily effort (.098), cosmetics (.065), and impact of treatment (.030). CONCLUSIONS: Soft-tissue surgery was judged best on outcome, daily effort, comfortable shoe wear, and cosmetically acceptable result and was thereby preferred as a treatment alternative by the panel in this study. In contrast, orthosis and orthopedic footwear are usually preferred in daily practice. The AHP method was found to be suitable methodology for eliciting subjective opinions and quantitatively comparing treatments in the absence of scientific evidence.

Neuroregeneration in composite tissue allografts: effect of low-dose FK506 and mycophenolate mofetil immunotherapy.

BACKGROUND: The immunosuppressant FK506 has been reported to increase the rate of peripheral nerve regeneration in nerve crush injury and nerve allograft models. The purpose of this study was to determine whether low doses of FK506 and mycophenolate mofetil had a neuroregenerative effect in revascularized peripheral nerve allografts in a rat hind limb transplantation model. METHODS: Wistar Furth rat recipients received limbs from syngeneic Wistar Furth donors (group 1, n = 4) or from allogeneic August X Copenhagen Irish rat donors (group 2, n = 6). Wistar Furth recipients received limbs from August X Copenhagen Irish donors and were treated with FK506/mycophenolate mofetil for 5 months (group 3, n = 7). At the end of the follow-up period, histomorphometric analysis of sciatic and tibial nerves from transplanted and intact hind limbs was conducted. Sciatic and tibial nerves were examined at the level of coaptation and near the neuromuscular junction, respectively. RESULTS: Transplanted limbs in groups 1 and 3 completed the study without rejection, while the limbs in group 2 were rejected within a few days. Sciatic and tibial nerve analysis in groups 1 and 3 limbs showed myelinated axons of various diameters but in significantly fewer numbers than in nontransplanted contralateral nerves. The number and size of myelinated axons of transplanted nerves at corresponding levels were not significantly different between syngeneic and allogeneic (FK506/mycophenolate mofetil-treated) transplants. CONCLUSIONS: The authors conclude that long-term neuroregeneration of revascularized peripheral nerves using low-dose FK506/mycophenolate mofetil was similar to that of syngeneic transplants. The occurrence of acute rejection episodes with low-dose FK506/mycophenolate mofetil did not appear to benefit nor impair neuroregeneration.

A critical review of foot orthoses in the rheumatoid arthritic foot.

Foot orthoses are commonly prescribed by health professionals as a form of intervention for the symptomatic foot in rheumatoid arthritis. However, there is a limited evidence base to support the use of foot orthoses in this patient group. This article provides a critical review of the use of foot orthoses in the management of rheumatoid arthritic foot pathologies. A search was conducted in the Cochrane Controlled Trials Register (current issue of the Cochrane Library), Physiotherapy evidence database (PEDro), Medline, The Cumulative Index to Nursing and Allied Health Literature (CINAHL) and Allied and Complementary Medicine (AMED) and from reference lists in journal articles. The language was restricted to English. Searching of the databases was undertaken between December 2004 and March 2005. The results indicated there is no consensus of opinion on the choice of foot orthoses used for the management of pathology in the rheumatoid foot, although there is strong evidence that foot orthoses do reduce pain and improve functional ability. The type of foot orthoses used ranged from simple cushioned insoles to custom-made rigid cast devices. Methodological issues raised included small sample size and poor use of valid and reliable outcome measures. There is limited evidence pertaining to cost-effectiveness. The results indicated a need for further investigation into the most clinically and cost-effective foot orthoses to prescribe in the management of the rheumatoid arthritic foot. This review highlights the need to identify the various types of foot orthoses that are most effective in the management of the established rheumatoid arthritic foot.

[Background of development and effectiveness of myanmar sandals (the activity of Leprosy Control and Basic Health Services Project in Myanmar)].

"Leprosy control and Basic health service Project" was terminated at March 2005 within the scope of the period. I was assigned to develop the Plantar protect footwear for neuropathic feet, which called "Myanmar Sandals" in common. These sandals are not made by new technologies but made by basic knowledge. I would like to report about this activity as which is a part of distinguished strategy of ODA (Official Development Assistance) for developing country, but not as the technical report of these sandals. There is only one National Leprosy Hospital in Myanmar. At the time this project started, there were only two footwear technicians for the people who had disabilities by after effect of Hansen's disease in this country. And, it would appear that the number of the people is over 50,000. Furthermore, the budget of national hospital is not enough to refill necessary consumable supplies and materials. Although, I should instruct new technique which like making in Japan in ordinary circumstances, I could not think that such technical transfer by using costly imported materials woud bring beneficial effect and be continued. We were bound to be anxious about such situations when we made the plan. As a result of examining a plan based on these situations, we reached the conclusion that development of the simplified ready-made footwear was pressing need.

The orthotic effect of functional electrical stimulation on the improvement of walking in stroke patients with a dropped foot: a systematic review.

OBJECTIVE: Analysis of the available evidence on the improvement of walking in stroke patients with a dropped foot when using peroneus stimulation. METHODS: A systematic review was performed to identify trials that investigated the orthotic effect of functional electrical stimulation (FES) on walking in stroke patients with a dropped foot. Two independent raters scored the methodological quality of the included articles. Walking speed and physiological cost index (PCI) were selected as the primary outcome measures. Studies that measured walking speed were pooled and a pooled difference including confidence interval was calculated. RESULTS: Eight studies were included in the review, of which one was a randomized controlled trial. Methodological score ranged from 8 to 18 out of 19. Six studies measured walking speed. The pooled improvement in walking speed was 0.13 m/s (0.07-0.2) or 38% (22.18-53.8). CONCLUSIONS: The present review suggests a positive orthotic effect of functional electrical stimulation on walking speed.

Functional electrical stimulation for a dropped foot.

The purpose of this collective review is to study the techniques, usage, methods, and clinical results of functional electrical stimulation applied to the peroneal nerve in the treatment of dropped foot. When stimulation is applied through surface electrodes, clinical reports have documented the therapeutic and orthotic benefits of functional electrical stimulation. Clinical trials are now being undertaken in which implantable electrodes are being used to stimulate the peroneal nerve in patients with dropped foot.

The shod foot and its implications for American women.

Throughout history, members of human societies have gone barefoot, and those societies seemingly had a low incidence of foot deformities and pain. Only one study has addressed the problem of infection through injury to the bare foot; otherwise, the unshod foot seems to have had minimal problems. Initially shoes were made in the shape of the foot and were sandals. Over time, shoes became decorative items and symbols of status and vanity. As the shape of shoes changed, they became deforming forces on the foot and the source of pain. Recent studies by the Council on Women's Footwear of the American Orthopaedic Foot and Ankle Society have tried to document the problems caused by shoes on the feet of American women. Attempts should continue to educate women on appropriate shoes and proper fit.

Psoriatic arthritis and acquired immunodeficiency syndrome.

We describe 2 patients who developed psoriatic arthritis during the course of acquired immunodeficiency syndrome. Both patients developed skin and articular involvement characteristic of psoriatic arthritis; these manifestations were refractory to conventional therapy. Our findings suggest that psoriatic arthritis should be added to the expanding spectrum of musculoskeletal manifestations of the acquired immunodeficiency syndrome.

The effect of previous treatment on the response of mouse feet to irradiation and hyperthermia.

The response of mouse feet to irradiation and heat was studied 90 days after a first treatment with X-rays, hyperthermia or both. Residual damage after a single dose of 20-30 Gy enhanced both the acute reaction and "late" deformity following a second treatment with radiation or hyperthermia. There was often a larger "memory" of the first radiation treatment for late deformity compared with the acute skin response, especially in the case of retreatment by hyperthermia. Prior treatment of the foot with a moderate heat dose (60 min at 44 degrees C), which by itself did not lead to deformity, had only a small effect on the response to retreatment with irradiation or heat, both with respect to the acute and "late" response. Residual damage after more severe hyperthermia (90 min at 44 degrees C) obscured the evaluation of deformity after a second treatment with radiation or hyperthermia. Feet treated with irradiation followed immediately or after 3 days by heat, show a larger "memory" when retreated with hyperthermia than with irradiation, both with regard to the acute and "late" response. Experiments using misonidazole indicated that the oxygenation status of previously treated skin (pretreatment not leading to deformity) had not changed significantly.

EMG biofeedback in tendon transplantation for foot drop.

EMG biofeedback training was used successfully to obtain the desired new function of dorsiflexion in the transplanted muscle for two patients with foot drop. The transplanted muscles are not working effectively, not only the active movement but also during a walk. It is concluded that EMG biofeedback training is useful in rehabilitation following tendon transplantation for foot drop.

Inversion or pronation of the foot following thalamotomy for Parkinson's disease.

The author has observed inward turning of the foot of 2 parkinsonian patients following thalamotomy on the contralateral side. In one instance, the surgery was unilateral and in the other bilateral. The anatomical position of the involved lesions was in the region of the complex of the ventrocaudal nuclei (ventralis posterolateralis). It appears that three elements are present whenever such pronation of the foot occurs, namely, paresis, hypertonicity, and impairment of sensory modalities such as localization, two-point discrimination and vibration.
