ABSTRACT. Fashion shoes with narrow and tight toe are widely designed for children and their influence was rarely considered. Therefore, the aim of this study is to investigate children's plantar pressure distribution with varied angle of hallux (AoH), so as to simulate the effect of the tight shoes on the children's feet. Totally, 892 healthy children aged between two and 11 were recruited and those with the foot deformities were excluded by an experienced clinical expert. Both the dynamic AoH and plantar pressure distribution were measured by a pressure plate, with the two-steps protocol and self-selected walking speed. Regions of Hallux, medial 2 forefoot (MFF), central forefoot (CFF), lateral forefoot (LFF), mid foot (MF) and Heel were considered and peak pressure (PP) (N/cm ), relative pressure time integral (PTIrel) (%) and relative contact area (CArel) (%) at each region were calculated. All the subjects were classified into nine groups according to the AoH with the 5° interval and within groups variations for each plantar pressure parameters were examined by the One Way ANOVA. Our results show that within group differences of PP, PTIrel and CArel existed at the Hallux, MFF and MF and phenomenon of hallux off-load and MFF and MF over-load was observed. Overall, lateral shift of the hallux changed the pressure pattern at MFF and MF and the pressure rising at those two areas could hamper the normal development of the foot arch in both longitudinal and transverse. Therefore, straight and wider footwear should be recommended to children's parents. KEY WORDS: fashion shoes; children; hallux valgus; plantar pressure ANALIZA DISTRIBUÞIEI PRESIUNII PLANTARE CU VARIAÞIA UNGHIULUI HALUCELUI LA COPII REZUMAT. Se concep pe scarã largã pantofi de modã cu vârful îngust ºi strâmt pentru copii, dar influenþa acestora a fost rareori luatã în considerare. Prin urmare, scopul acestui studiu este de a investiga distribuþia presiunii plantare cu variaþia unghiului halucelui (AoH) la copii, pentru a simula efectul pantofilor strâmþi asupra picioarelor copiilor. În total, 892 de copii sãnãtoºi cu vârste cuprinse între doi ºi 11 ani au fost recrutaþi, iar cei cu diformitãþi ale piciorului au fost excluºi de cãtre un specialist cu experienþã. AoH în dinamicã ºi distribuþia presiunii plantare au fost mãsurate folosind o placã de presiune, cu un protocol în doi paºi, iar viteza de mers a fost la libera alegere a subiectului. S-au luat în considerare urmãtoarele zone: haluce, antepicior median (MFF), antepicior central (CFF), antepicior lateral (LFF), 2 partea medianã a piciorului (MF) ºi zona cãlcâiului ºi s-au calculat presiunea maximã (PP) (N/cm ), integrala relativã presiune-timp (PTIrel) (%) ºi zona de contact relativã (CArel) (%) în fiecare zonã. Subiecþii au fost împãrþiþi în nouã grupe, în funcþie de AoH cu un interval de 5° ºi variaþiile între grupe pentru fiecare parametru de presiune plantarã au fost examinate utilizând One Way ANOVA. Rezultatele noastre aratã cã s-au înregistrat diferenþe între grupe cu privire la PP, PT...

“…Considering radiological parameters the preoperative HVA was found to be the most reliable radiological indicator and the best predictor for expected correction of deformity. 1,19 We achieved at follow-up a mean HVA angle of 14.5 , which is satisfactory. According to Bö sch an HV between 5 and 25 is in general cosmetically accepted.…”

Distal metatarsal osteotomy Hallux valgusMini-invasive surgery a b s t r a c t Objectives: To evaluate the early clinical and radiological results using the Bö sch technique to treat hallux valgus. Material and methods:We reviewed retrospectively four patients with 6 feet undergoing the Bö sch technique for mild and moderate hallux valgus from 2009 to 2012 with an average follow-up of 10.8 months. All patients complained of pain around the first metatarsophalangeal joint. They had cosmetic concerns, and difficulty in wearing shoes. At final follow-up patients were asked about the improvement of pain, cosmetic appearance of the foot, problems with wearing shoes, the ability to walk, and their satisfaction with the operation. Complications encountered were also recorded. The radiographic evaluation considered osteotomy site union, the hallux valgus angle, and the intermetatarsal angle.Results: All patients complained of mild or no pain. They had a satisfactory cosmetic result, wore normal shoes without problems with no limitation of walking ability. They were satisfied with the procedure. One case of superficial infection was noticed. All osteotomies healed primarily within three months. The average hallux valgus angle improved from 32.7 preoperatively to 14.8 at final follow-up and the average intermetatarsal angle from 17.5 to 9.2 . Conclusion:The Bö sch technique is a cost effective procedure that yields good clinical and radiological results while correcting mild and moderate symptomatic hallux valgus with reduced risk of surgery related complications.

TanımHalluks valgus toplumda sık görülen, sıklığı giderek artan ayak başparmağının ilerleyici ve sıklıkla ağrıya sebep olan hastalığıdır. Tedavi edilmediği takdirde iş gücü kaybı, yaşam kalitesi bozukluğu ve estetik problemlere yol açar [1]. Hallux valgus için çe-şitli tanımlamalar yapılmış olup bir çok patolojinin bir arada olduğu bir kompleks ifadesi ile en ayrıntılı ve uygun tanımlama Helal tarafından aşağıdaki şekilde yapılmış-tır. [3,9,11,12]. 10) İkinci parmağın amputasyonu: Başparmağın lateral desteği kaybolduğu için halluks valgus gelişebilir [7,11]. 11) Ayakta pronasyon meydana getiren ve birinci MTP eklem dışındaki sebepler: Tibialis posterior tendon rüptürü, subtalar eklemin valgus deformitesi, aşil tendon kı-salığı, jeneralize eklem laksitesi ( Ehlers-Danlos sendromu), birinci MTP eklemin hipermobilitesi halluks valgus'a sebep olabilir [7,9,11,13,14]. 12) Kistik dejenerasyon: Birinci MTP eklemin medial kapsülünün kistik dejenerasyonu ganglion oluşturarak deformite oluşumuna sebep olabilir.
