Tratamiento quirúrgico del Hallux Valgus severo mediante cirugía percutánea. Estudio estadístico de los resultados clínicos, radiológicos y funcionales del tratamiento mediante la colocación de un implante intermetatarsiano

La cirurgia percutània en el tractament del hallux valgus és cada vegada més utilitzada, encara que compta amb limitacions en els casos severs. Es tracta d'un estudi retrospectiu en el qual s'analitzen estadísticament els resultats clínics, radiològics i funcionals del tractament quirúrgic del Hallux Valgus sever mitjançant cirurgia percutània amb la col•locació d'un dispositiu intermetatarsiano. Hi ha una bona correcció de l'angle intermetatarsiano i de l'angle hallux valgus, així com una millora clínica i funcional estadísticament significativa amb la utilització d'aquesta tècnica, sent els seus resultats comparables a aquells obtinguts amb la cirurgia oberta.

Hallux valgus: résumé pratique [Hallux valgus: practical summary].

Hallux valgus arises from static and dynamic unbalance of the forefoot. Possibilities of conservative treatment are limited. This paper recalls the essentials of physiopathology and exposes briefly to the non-operators the most current amongst 150 operative techniques described. While becoming more complex, the surgery of hallux valgus has proven to gain efficiency. Surgical indication, based on biomechanics, should be very careful, which gives a greater interest to this discipline.

The scarf osteotomy for the treatment of hallux valgus deformity: a review of 84 cases.

This study reviewed the subjective, clinical and radiological outcome of 71 patients (84 feet) treated by scarf osteotomy for hallux valgus deformity at our institution from 1995 to 1998 with an average follow-up time of 22 months (range, 17 to 48 months). At the time of follow-up, 39% of the patients were very satisfied, 50% were satisfied and 11% were not satisfied. The mean AOFAS score raised significantly from 43 points (14-68) preoperatively to 82 points (39 to 100) at follow-up (p < 0.001). The radiological angles including M1-M2, M1-P1, M1-M5 and DMAA improved significantly (p < 0.001). Among the 16 complications recorded, seven (8%) were minor and nine (11%) required an additional procedure. The scarf osteotomy of the first metatarsal coupled with a lateral soft-tissue release and, in three-quarters of our cases, with a basal closing wedge varisation osteotomy of the first phalanx, resulted in overall high satisfaction rate as well as significant clinical and radiological improvements in our series. Nevertheless, the range of motion of the first MP joint remained low: 30 degrees to 74 degrees in 52 patients (62%) and <30 degrees in four patients (5%). Furthermore, the mobility of the first ray as well as the consequences of the procedure in the sagittal plane need to be assessed more accurately, and this may be achieved by incorporating measurement of the plantar pressures in the forefoot area into the global rating system.

Characterization of gait in female patients with moderate to severe hallux valgus deformity.

BACKGROUND: Hallux valgus is one of the most common forefoot problems in females. Studies have looked at gait alterations due to hallux valgus deformity, assessing temporal, kinematic or plantar pressure parameters individually. The present study, however, aims to assess all listed parameters at once and to isolate the most clinically relevant gait parameters for moderate to severe hallux valgus deformity with the intent of improving post-operative patient prognosis and rehabilitation. METHODS: The study included 26 feet with moderate to severe hallux valgus deformity and 30 feet with no sign of hallux valgus in female participants. Initially, weight bearing radiographs and foot and ankle clinical scores were assessed. Gait assessment was then performed utilizing pressure insoles (PEDAR®) and inertial sensors (Physilog®) and the two groups were compared using a non-parametric statistical hypothesis test (Wilcoxon rank sum, P<0.05). Furthermore, forward stepwise regression was used to reduce the number of gait parameters to the most clinically relevant and correlation of these parameters was assessed with the clinical score. FINDINGS: Overall, the results showed clear deterioration in several gait parameters in the hallux valgus group compared to controls and 9 gait parameters (effect size between 1.03 and 1.76) were successfully isolated to best describe the altered gait in hallux valgus deformity (r(2)=0.71) as well as showed good correlation with clinical scores. INTERPRETATION: Our results, and nine listed parameters, could serve as benchmark for characterization of hallux valgus and objective evaluation of treatment efficacy.

Morphometric Analysis of the Extensor Tendons of the Hallux and Potential Implications for Tendon Grafting

Although several tendon sources are available for reconstructive surgical procedures, all have one or more shortcomings. The aim of this work was to evaluate if the extensor tendons of the hallux showed anatomical characteristics that could make them an additional source for tendon grafting procedures.The authors performed a detailed morphometric analysis of the extensor tendons of the hallux in 26 lower limbs in order to evaluate the putative association of anatomical variants with hallux valgus, and to attempt to assess the feasibility of using part of the extensor apparatus of the hallux as a source of tendon for grafting procedures.An accessory extensor hallucis longus ten-don was found in 92.3% of cases. The extensor hallucis brevis tendon length was 10.5 ± 0.6 cm; its width was 0.5 ± 0.1 cm, and its thickness varied between 1-2 mm, making it a potentially good candidate as a source of ten-don grafts. Several anatomical variations were observed, namely the fusion of the tendons of the extensor hallucis brevis and the accessory extensor hallucis longus muscles in the distal part of the foot.This new therapeutic option, if implemented, would possibly increase the supply of autogenous donor tissue for reconstructive procedures, thereby enhancing the reconstructive surgeon’s armamentarium.

Hallux rigidus: Arthroplasty or arthrodesis. What technique produces better results?

Hallux rígidus (HR) affects the first metatarsophalangeal joint (MTPJ) between 35% and 60% of the population over 65 years and there are multiple ways of treatment. Depending on the radiological stage where you find the deformity determines the procedure to be performed; in the early stages cheilectomy techniques and corrective osteotomy is performed while the more advanced ratings, the surgeon chooses destructive techniques considered as arthrodesis and arthroplasty. This final of degree project aims to focus on 1 MTPJ destructive techniques to clarify which of the procedures generates better results by a number of parameters; outcomes of the American Orthopaedic Foot scale and Ankle Society Hallux metatarsophalangeal Interphalangeal-scale (AOFAS), range of motion (ROM) of the 1ºAMTF, radiological classification. As for the implant arthroplasty technique, this article offers information on material and design that generates better relating to patient characteristics such as age, inflammatory joint diseases, viability and durability of the implant results. The conclusion from this review is that the values obtained in the arthrodesis according AOFAS decrease due to loss of mobility, but both techniques have similar values of effectiveness and concludes with the decision that the technique used is determined taking into account various factors and patient characteristics.
