Lateral ankle sprains account for 85% of lesions.Combined open and arthroscopic procedures could improve the diagnosis management intra-articular lesions allow surgeons to perform minimally invasive anatomic reconstruction lateral ligament complex.Case series; Level evidence, 4.Forty consecutive patients underwent arthroscopy recurrent (2 or more episodes) instability unresponsive nonoperative measures. The clinical mechanical was confirmed at imaging (plain radiographs magnetic resonance...
Background: Anatomical dissection of the second metatarsophalangeal (MTP) joint suggests that plantar plate is major stabilizing structure due to its central location and multiple important attachments. Many surgical procedures have been recommended when conservative treatment has failed, but some had limited clinical success. The aim our prospective study was show results obtained in a group patients with tears by direct repair through dorsal approach combined Weil metatarsal osteotomy...
Instability of the lesser metatarsophalangeal (MTP) joints is a common cause deformity and pain. The purpose this study was to prospectively evaluate surgical outcomes for different grades plantar plate tears propose treatment protocol.Sixty-eight patients (100 MTP joints) were enrolled graded according anatomical grade system tears. Based on classification, appropriate procedure chosen as follows: 0 I, thermal shrinkage with radiofrequency; II III, direct reinsertion plate; IV,...
Arthroscopic ankle lateral ligament repair techniques have recently been developed and biomechanically as well clinically validated. Although there has 1 anatomic study relating suture anchor proximity to structures, none evaluated the ArthroBroström procedure.To evaluate of structures for stabilization technique define ideal landmarks "safe zones" this repair.Descriptive laboratory study.Ten human cadaveric specimens (5 matched pairs) were screened study. All underwent arthroscopic...
The Distal Metatarsal Articular Angle (DMAA) was previously described as an increase in valgus deformity of the distal articular surface first metatarsal (M1) hallux (HV). Several studies have reported poor reliability this measurement. Some authors even called into question its existence and consider it to be consequence M1 pronation resulting projection round-shaped lateral edge head.Our study aimed compare DMAA HV control populations, before after computer correction plantarflexion with a...
Results of biplanar chevron osteotomy performed on patients with mild-to-moderate hallux valgus deformity an increased distal metatarsal articular angle (DMAA) are shown. The study included clinical data 32 (54 feet) who had completed a 2-year follow-up, and radiological these other 29 (50 for total 61 (104 feet, 53 right 51 left). There were 59 females two males ages varying from 11 to 66 years. According the AOFAS Hallux Rating, preoperative average score (50) improved 90 (average after...
Adult-acquired flatfoot deformity (AAFD) is usually due to a combination of mechanical failure the osteoligamentous complex that maintains medial longitudinal arch foot and attenuation or complete tear posterior tibial tendon. Magnetic resonance imaging studies in patients with deformities have reported tendon be pathologic up 100% patients, spring ligament 87%, deltoid 33%. Many literature describe reconstruction associated AAFD, but there no study which both (spring deltoid) ligaments are...
Summary Chronic ankle instability following sprains causes pain and functional problems such as recurrent giving way. If non-operative treatments fail, then operative stabilization may be required to improve function. Operative options include both anatomic repair reconstruction techniques. Anatomic techniques utilize pre-existing ligament remnants that are either reattached or tightened stability of the ankle. structures have been damaged beyond insufficient allow repair, it is appropriate...
The high frequency of hallux valgus deformities in females is well known and has been widely reported the literature. This finding tends to obscure importance characteristic details males. severity deformity, its onset at an earlier age, inheritability seem be more frequent males, but there are no reports literature substantiate these concepts. purpose this study was analyze questions regard males with valgus.The records plain radiographs 31 (53 feet) a diagnosis that were treated over...
Background: When nonsurgical treatment of a Morton neuroma is unsuccessful, neurectomy indicated. The purpose the present retrospective study was to evaluate long-term outcomes, complications, and adverse events following distal plantar transverse incision for excision an intermetatarsal neuroma. Methods: We conducted review 168 consecutive patients who underwent surgical that had been unresponsive treatment. clinical diagnosis confirmed by means magnetic resonance imaging histological...
The objective of our study was to assess the diagnostic performance and associations direct indirect MRI features metatarsophalangeal (MTP) joint that are thought be related tears plantar plate (PP) using surgical findings as reference standard.We retrospectively included 23 patients with symptomatic instability lesser MTP joints who had undergone preoperative 1.5-T assessment. examinations were independently assessed by two musculoskeletal radiologists. Using data standard, we calculated...
The Achilles tendon (AT) is the toughest and most robust in human body. However, it frequently injured. Several surgical techniques are described literature for treating chronic or complex injuries. Some of them use transfers peroneus brevis, flexor digitorum longus hallucis (FHL). FHL transfer can be performed endoscopically (minimally invasive), a reliable method AT ruptures. objective this study was to describe technical tip allow surgeons harvest longer graft using stripper without need...
Objetivo: A osteoartrose do tornozelo pode ser um desfecho final de afecções traumáticas e clínicas que afetam esta articulação. Múltiplos fatores como a própria morfologia alinhamento articular associado forças extrínsecas ao articulações circunjacentes influenciam nessa patologia assim nos resultados procedimento cirúrgico escolhido para tratá-la. Parâmetros radiográficos na literatura definem relação normal entre tíbia o tálus, porém não dispomos dados populacionais significativos....
Background: Instability of the lesser metatarsophalangeal (MTP) joints has been widely reported and plantar plate insufficiency is a key part this pathologic process. The diagnosis made clinically but can be aided by imaging studies, particularly magnetic resonance (MRI); however, sensitivity accuracy method compared to direct visualization these lesions not yet established, nor interobserver MRI assessed for evaluation pathology. In study, our goals were identify in describing tears when...
