This procedure was quite successful, particularly in patients with a transverse plane dominant flexible pes valgus deformity. The modifications that have proved to be successful include the use of the oblique skin incision following the relaxed skin tension lines, the use of allogeneic bone graft, and the use of ancillary procedures, including the gastrocnemius recession and medial arch tendosuspension. The procedure is less predictable in those patients whose deformity is primarily in the frontal or sagittal plane. It is most critical that preoperative analysis be used to discover the presence of the masked metatarsus adductus prior to performing this procedure. 相似文献

Pes planus or flatfoot becomes a medical problem only when symptoms develop. The mere absence of a well-formed medial longitudinal arch does not necessarily imply pathology. Many apparently "flat feet" demonstrate congruent joints, and the extremities function normally. The size and shape, as well as the angles of declination for the talus or astragulers and the calcaneus or os calcis, are most often determined at the moment of fertilization by the genes of the patients. The zygote or fertilized ovum is a first totipotent. Cell division normally occurs as development proceeds, but the embryo is vulnerable to alterations of the cell cycle. Teratogenic substances can induce death or substantial structural modifications to the developing fetus. The post-World War II tragedy of the medical use of the drug thalidomide in pregnant mothers resulting in amelia is testimony as to how the lower extremity can be adversely affected. Early chromosomal aberrations including duplication, deletion, breakage, inversion, translocation, and mosaicism have been shown to be involved in faulty development of the foot, and there is no reason not to implicate pes valgo planus to these events. Intrauterine development apart from the genetic considerations just mentioned place the fetus under additional jeopardy. Even extraembryonic membranes can form strands of tissue that can entangle the delicate developing foot plate, and calcaneovalgus deformities could conceivably be established. The developing embryo and fetus first demonstrate a blastema that forms limb buds on the ventral caudal aspect. Anlage of the scleroblastema and myoblastema of the prospective leg and foot develop in the presence of nerve trunks. Such nerves are related to the lumbosacral plexus and they are thought to exert inductive developmental influences. Interference with any of these events may be implicated in pedal deformities such as pes valgo planus. This is also true of subsequent morphogenetic events involving embryonic rotations, osteogenesis, and myogenesis. Many pedal deformities have congenital basis and it is clear that pes valgo planus is one of them. Post-natal structural changes further accentuate underlying etiologies. For example, the calcaneus normally exhibits a varus position at birth, but this feature diminishes until the cessation of bone growth. The adult talar neck-calcaneal angle is normally about 24 degrees, representing a 6-degrees reduction from that of 30 degrees, which is demonstrated at birth.(ABSTRACT TRUNCATED AT 400 WORDS) 相似文献

The Evans calcaneal osteotomy is used to correct the flexible flatfoot deformity. The procedure restores functional integrity to the medial longitudinal arch and reestablishes the locking mechanism of the midtarsal joint complex. A preliminary analysis of 36 cases (50 feet) performed at Atlanta Hospital and Medical Center during the past 3 years has yielded favorable results. 相似文献

Background
Despite being a common condition, there are no objective measures in the literature to reflect the burden of pes planus on affected individuals. Our primary objective was to evaluate this burden by recruiting a sample from the general population using validated utility outcome measures.Methods
Participants were recruited online and filled a questionnaire to help measure the health burden of pes planus. Three recognized utility outcome scores were used to compare the health burden of monocular blindness, binocular blindness, and pes planus. These included the standard gamble (SG), time trade-off (TTO), and visual analogue score (VAS). Paired t test, independent t test, and linear regression were used for statistical analysis.Results
Ninety-two participants were included in the final analysis. The utility outcome scores (VAS, TTO, SG) for pes planus were 73 ± 17, 0.90 ± 0.08, and 0.88 ± 0.12, respectively. The linear regression analysis showed that age was inversely proportional to the time trade-off. However, race, educational level, and income were not significant predictors of utility outcome score for pes planus.Conclusions
This study shows that the perceived burden of living with pes planus is comparable to living with some debilitating conditions. Our participants were willing to sacrifice 3.6 years of life, and have a procedure with a theoretical 12% mortality risk to attain perfect health. 相似文献7.

Double osteotomy of the first metatarsal is an option in treatment of severe hallux valgus deformity. Good short-term results have been reported with percutaneous surgery in hallux valgus with moderate deformity. We report short-term results with percutaneous double osteotomy of the first metatarsal in severe deformities. This is a prospective study of 6 patients with severe hallux valgus deformity who were treated with percutaneous double osteotomy of the first metatarsal (proximal closing wedge and distal chevron osteotomy) in 2008. They were assessed preoperatively and one year and two years after surgery, with clinical and radiological AOFAS MTP-IP score. All patients were satisfied. The AOFAS score improved from 34 to 84. The postoperative radiological assessment showed significant improvement, compared with preoperative values of the intermetatarsal and hallux valgus angles. No complications were encountered. Post-operative stiffness of the first MT joint was observed but resolved after physiotherapy. This preliminary study showed that correction of severe hallux valgus deformity by percutaneous double osteotomy can achieve good clinical and radiological results. A larger number of cases with a longer follow-up is needed to firmly demonstrate the advantages of this technique compared with classical open surgical techniques in the treatment of severe hallux valgus deformities. 相似文献

Various methods of performing proximal femoral realignment in adolescents with severe slipped capital femoral epiphysis exist. We report the technique and early results of a percutaneous, opening wedge subtrochanteric femoral osteotomy using an external fixator for correcting multiplanar deformities in such patients. Nine adolescents with severe slipped capital femoral epiphysis underwent a percutaneous osteotomy at an average age of 14.5 years. Mean operative blood loss was 61 ml, with 2 days of inpatient stay and 129 days of external fixation time. At an average follow-up of 23 months, hip flexion improved from 74 to 106 degrees, internal rotation from -5 to +17 degrees, external rotation from 71 to 41 degrees and abduction from 29 to 36 degrees. Radiographs revealed an improvement in anteroposterior head shaft angle from 112 to 134 degrees and lateral head shaft angle from 72 to 15 degrees. One patient had transient chondrolysis. No fixation-related problems, deep infection, avascular necrosis or refracture occurred. On the basis of our preliminary results, this percutaneous technique offers several advantages over currently available methods for surgical correction of severe slipped capital femoral epiphysis deformities. 相似文献

A review of five distinct medial column stabilization procedures sets forth criteria specific to certain presentations of pes planus deformity. The importance of considering the manifestation of the condition and its implications with regard to the overall health of the particular patient cannot be overemphasized. The collective goal of all such corrective procedures is identical; it is the variable factors particular to a specific presentation that dictate the preferred corrective action. The course selected by a physician with respect to surgical correction of flexible pes planus must be determined by taking both the procedure and the presentation of the condition under advisement. 相似文献

The purpose of this study was to evaluate the combination of talonavicular fusion and Evans calcaneal osteotomy for the treatment of posterior tibial tendon dysfunction. This was a retrospective study of 10 patients, mean age 48.7 years, who had continued pain despite 6 months of conservative treatment and a minimum Johnson and Strom stage II deformity. Patients completed a detailed questionnaire, were physically examined, and their postoperative improvement was graded according to the American Orthopedic Foot and Ankle Society Ankle-Hindfoot Rating Scale. At a mean of 35 months (range 8-72 months) after surgery, patients demonstrated a significant improvement (p<.001) both in their subjective discomfort and in the structural alignment and function of their feet. The authors feel that this combination of procedures allows greater correction and stability than either procedure performed alone, and provides a viable alternative to triple arthrodesis. 相似文献

This posteriorly placed, extra-articular, calcaneal osteotomy was developed at the Atlanta Hospital and Medical Center, Atlanta, Georgia. Using a posterior, transverse approach, a frontal or sagittal plane Z-plasty lengthening of the Achilles tendon is performed to gain access to the superior aspect of the calcaneal body. An opening wedge osteotomy is then directed posterior-dorsal to anterior-plantar, to effectively plantarflex the posterior aspect of the calcaneus. It is indicated in clinical conditions involving a sagittal plane flatfoot with minimal heel valgus. 相似文献

BackgroundThe present study aimed to investigate changes in hallux alignment after corrective surgery for adult-acquired flatfoot deformity (AAFD).Patients and methodsThe present study retrospectively investigated the changes of hallux alignment in 37 feet (33 patients) which were treated with double or triple arthrodesis of the hindfoot for AAFD between 2015 and 2021 and could be followed up to one year postoperatively.ResultsHallux valgus (HV) angle significantly decreased by a mean 4.1° among the whole 37 subjects and by a mean 6.6° among the 24 subjects who had a preoperative HV angle of 15° or more. Those who had HV correction (HV angle correction ≥ 5°) demonstrated more near-normal postoperative alignment of the medial longitudinal arch and hindfoot than those without HV correction.ConclusionsHindfoot fusion for AAFD could improve preoperative HV deformity to some degree. HV correction was associated with proper realignment of the midfoot and hindfoot.Level of evidenceLevel IV; retrospective case series 相似文献
