Comparative study of two retrograde locked intramedullary nail designs for ankle arthrodesis: A finite element analysis.

Ankle arthrodesis is the gold standard for treatment of end-stage arthritis. The goal of ankle arthrodesis is to obtain bony union between the tibia and the talus. Retrograde intramedullary nailing is typically reserved for ankle and subtalar joints arthrodesis.

[Pronostic factors associated with the results of subtalar arthrodesis].

Introduction: Subtalar arthrodesis is a surgical stabilization procedure in the isolated pathology of the subastragaline joint that does not respond to conservative treatment, its goal is to obtain a solid fusion of the joint to eliminate or improve pain and function, normalizing the distribution of foot loads and alignment of the foot. There are studied variables that interfere with the surgical outcome of patients treated with subtalar arthrodesis such as: smoking, age, sex, osteoarthritis, BMI, rehabilitation, osteosynthesis material and surgical technique.

Objective: To know the prognostic factors associated with the results of subastragaline arthrodesis.

[Short-term results of Weils osteotomy in patients with propulsive metatarsalgia].

Introduction: Metatarsalgia is the most common reason for consultation in orthopedic pathology of the foot. The key to its treatment lies in the correct determination of the symptoms, which are biological, morphological and mechanical alterations responsible for pain. Weil´s osteotomy is commonly used for multiple forefoot pathologies, including metatarsalgias.

[Retrograde intramedullary nail fixation for Charcot neuroarthropathy].

Unlabelled: Charcot arthropathy is defined as an articular degenerative, chronic, progressive disease that affects one or more peripheral joints, develops as a result of a failure in the normal sensory perception (pain and proprioception) in the innervation of joints located in the foot and ankle, is characterized by destructive bone lesions without the presence of infection. Neuropathy is directly associated with diabetes mellitus type 1 and 2. Surgery is indicated when there is severe involvement of soft tissue, foot joints are unstable, at the presence of chronic or recurrent ulcers or when the foot and ankle can not fit to a normal shoe, and had limitation to perform activities of daily living.

[Charcot arthropathy and diabetic foot].

Diabetes mellitus is a major chronic degenerative disease, which currently is taking on alarming proportions in the population of our country. Neuropathic arthropathy is one of the most interesting degenerative joint disorders and increasingly common within the orthopedic pathology. It is defined as a progressive degenerative arthropathy, chronic and affecting one or more peripheral joints, and develops as a result of the lack of sensory perception normal in the innervation of joints.

[Surgical management of anterior cavas foot in Charcot-Marie-Tooth patients. Five-year follow-up].

Unlabelled: Hereditary sensorimotor neuropathy involves foot deformities such as varus and cavus foot and claw toes. Several surgical techniques have been described to treat Charcot-Marie-Tooth disease.

Objective: To assess the clinical and functional result of "V" basal osteotomy of the central metatarsals with elevation of the first metatarsal, dorsal osteotomy plus closing osteotomy, and elevation of the fifth metatarsal in Charcot-Marie-Tooth patients during a five-year period.

[Tarsal tunnel syndrome secondary to venous insufficiency. Case report].

Tarsal tunnel syndrome is defined as an extrinsic and/or intrinsic compressive neuropathy of the posterior tibial nerve or one of its branches. Its causes include venous insufficiency. Clinical case: 51 year-old female patient from León, Guanajuato.

[Tarsal tunnel syndrome. Review of the topic as a result of one case].

The first description of tarsal tunnel is attributed to Richter in 1897, in 1932 Pollock and Davis described the syndrome for the first time, in 1960 Kopell and Thompson described the clinical features of tarsal tunnel syndrome; and in 1962 Charles Keck described tarsal tunnel syndrome in a detailed manner with clinical cases. We present the case of a 61 year old female patient who presented symptoms in 2010, she had intermittent talalgia that increased gradually, six months later pain is constant and limiting gait, EVA is 6/10, she is diagnosed with plantar fasciitis and is referred to physiotherapy with no improvement after two months of treatment. The plantar fascia ultrasound reports thickening with micro tears in the heel bone attachment, we infiltrated the plantar fascia with platelet rich plasma with no improvement, two months later she has shock wave sessions with no changes observed.

[Dynamic plantar pressure distribution after percutaneous hallux valgus correction using the Reverdin-Isham osteotomy].

Percutaneous surgical techniques are suitable for the correction of the hallux valgus deformity. Satisfactory aesthetic and functional results obtained with the Reverdin- Isham osteotomy have been reported. The aim of this study was to describe dynamic plantar pressure redistribution after the correction of the deformity using this technique.

[Modification of Scarf osteotomy for the treatment of hallux valgus].

Objectives: To show that the modified scarf osteotomy for hallux valgus surgery provides a greater basal contact surface, which results in more stability and less complications for the management of the metatarsus primus varus, and helps define its indications.

Material And Methods: Longitudinal, ambispective trial conducted between 2005 and January 2012 in patients with hallux valgus and metatarsus primus varus, with a statistical analysis using Student's T test to compare the preoperative and postoperative values of the American Orthopaedic Foot & Ankle Society scale.

Results: 58 modified scarf osteotomies were performed in 46 patients; there were 12 bilateral patients.

[Pirogoff amputation. Report of two cases and literature review].

Pirogoff amputation was originally described by Russian surgeon Nicholas Pirogoff in 1864. It refers to the osteoplastic amputation distal to the ankle joint, talus resection and bone fusion of the tibia and the calcaneus. Its advantages are as follows: less loss in limb length, the possibility of full weight bearing, and the use of a more anatomical prosthesis.

[Platelet-rich plasma for managing calcaneus tendon tendinopathy and plantar fasciitis].

Introduction: Non-surgical treatment of Achilles tendinopathies ad plantar fasciitis has shown good results in up to 90% of cases. However, the remaining 10% of patients with these conditions represent a true challenge for the orthopedic surgeon. New technologies for the development of orthobiologic materials make it possible to use platelet-rich plasma (PRP) as an alternative to treat cases that have been refractory to prior treatment and that have a chronicity exceeding 12 months.
