Dorsiflexion has been studied in three normal feet and in three feet with talipes equinovarus to determine the anatomical features which might contribute to the failure of operative treatment to correct the deformity. In the normal feet the movement of dorsiflexion was found to be essentially rotatory in nature and not simply hinging; as dorsiflexion proceeds the fibula moves forwards relative to the os calcis and the calcaneal tendon. In the club feet a posterolateral tether was found; this prevented fibular movement and blocked dorsiflexion. As a result of this study a posterior and lateral release is advocated for the operative correction of the hindfoot in a child with a club foot deformity, particularly under the age of a year

Subcutaneous rupture of the tendon of tibialis anterior immediately proximal to its insertion affects patients over the age of 45 years and is most common in the seventh decade. The symptoms at the time of rupture are milder than is the case with rupture of the calcaneal tendon and the early disability is slight. Thus, affected patients commonly present several weeks or months after rupture and at a stage when reattachment of the tendon to its normal site of insertion (the most satisfactory surgical management) is impossible. Although the disability is slight if repair is not performed, there should be no disability after surgical repair and this should be offered to those patients who lead an active life and who present in the first three months after rupture. The relevant literature is reviewed and experience with four further patients is recounted

In 20 skeletally mature female merino sheep, divided into four groups, we performed total medial meniscectomy, removal of the middle third of the patellar tendon, and tenotomy of the calcaneal tendon of the right hind leg. Group I (control) had no additional procedures. In the other three groups the medial meniscus was replaced by the middle third of the patellar tendon from the ipsilateral knee. The animals were killed at three (group II), six (group III), or 12 months (group IV) and the tendon-meniscus examined macroscopically, by light and scanning electron microscopy, and biomechanically. Remodelling of the tissue had taken place by 12 months but the failure stress and tensile modulus for the tendon-meniscus were lower than for the normal meniscus. Our evidence suggests that, in sheep, replacement of a meniscus by a tendon autograft may decrease the severity of the degenerative changes that occur after meniscectomy

Aims

High-grade dysplastic spondylolisthesis is a disabling disorder for which many different operative techniques have been described. The aim of this study is to evaluate Scoliosis Research Society 22-item (SRS-22r) scores, global balance, and regional spino-pelvic alignment from two to 25 years after surgery for high-grade dysplastic spondylolisthesis using an all-posterior partial reduction, transfixation technique.

Aims

Preoperative talar valgus deformity ≥ 15° is considered a contraindication for total ankle arthroplasty (TAA). We compared operative procedures and clinical outcomes of TAA in patients with talar valgus deformity ≥ 15° and < 15°.

Background

Due to the overwhelming demand for trauma services, resulting from increasing emergency department attendances over the past decade, virtual fracture clinics (VFCs) have become the fashion to keep up with the demand and help comply with the BOA Standards for Trauma and Orthopaedics (BOAST) guidelines. In this article, we perform a systematic review asking, “How useful are VFCs?”, and what injuries and conditions can be treated safely and effectively, to help decrease patient face to face consultations. Our primary outcomes were patient satisfaction, clinical efficiency and cost analysis, and clinical outcomes.

1. In a club foot the small inverted and elevated heel is considered to be the most important deforming influence in preventing complete correction and in promoting relapse. 2. Correction of the varus and an increase in the vertical height of the heel are achieved by opening up the medial aspect of the calcaneum and inserting a wedge of bone. This abolishes the inverting action of the calcaneal tendon and brings the heel down on to the ground directly under the line of the tibia so that it touches first in walking. The weight is then shifted on to the forefoot, as in the normal gait, thus producing gradual correction of supination and adduction. 3. The operation may have to be repeated, but with the varus fully corrected and a plantigrade heel there is no chance of relapse, and progressive improvement, not only in gait and shoe wear but also in the development of the foot and leg, can be expected. 4. Skin closure is a difficulty, and though the resulting scar is sometimes conspicuous, it is masked to some extent by being on the postero-medial aspect of the ankle. 5. The ideal age for the operation is about three to four years, but there is virtually no upper age limit. 6. In older patients presenting severe residual deformity it may be necessary to correct the heel and then the equinus of the forefoot by a tarso-metatarsal wedge, thus avoiding damage to the mid-tarsal and subtalar joints. 7. By adopting these principles, soft-tissue release operations, so often disappointing and sometimes damaging, can be avoided and in no patient should there ever be the need to resort to the mutilating "triple wedge" resection. 8. The most important feature of the operation is correction of the varus; it is better to over-correct than to under-correct (Figs. 20 and 21). It is a simple matter to deal with the valgus later if necessary

Objectives

The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits.

Aims

The treatment of tibial aplasia is controversial. Amputation represents the gold standard with good functional results, but is frequently refused by the families. In these patients, treatment with reconstructive limb salvage can be considered. Due to the complexity of the deformity, this remains challenging and should be staged. The present study evaluated the role of femoro-pedal distraction using a circular external fixator in reconstructive treatment of tibial aplasia. The purpose of femoro-pedal distraction is to realign the limb and achieve soft tissue lengthening to allow subsequent reconstructive surgery.

Aims

The purpose of this study was to evaluate the in vitro effects of apocynin, an inhibitor of nicotinamide adenine dinucleotide phosphate oxidase (NOX) and a downregulator of intracellular reactive oxygen species (ROS), on high glucose-induced oxidative stress on tenocytes.

Aims

There is little information about how to manage patients with a recurvatum deformity of the distal tibia and osteoarthritis (OA) of the ankle. The aim of this study was to evaluate the functional and radiological outcome of addressing this deformity using a flexion osteotomy and to assess the progression of OA after this procedure.

Aims

Proliferation, migration, and differentiation of anterior cruciate ligament (ACL) remnant and surrounding cells are fundamental processes for ACL reconstruction; however, the interaction between ACL remnant and surrounding cells is unclear. We hypothesized that ACL remnant cells preserve the capability to regulate the surrounding cells’ activity, collagen gene expression, and tenogenic differentiation. Moreover, extracorporeal shock wave (ESW) would not only promote activity of ACL remnant cells, but also enhance their paracrine regulation of surrounding cells.

Aims

The integrity of the soft tissue envelope is crucial for successful treatment of infected total knee arthroplasty (TKA). The purpose of this study was to evaluate the rate of limb salvage, infection control, and clinical function following microvascular free flap coverage for salvage of the infected TKA.

Aims

We hypothesized that there is no difference in the clinical and radiological outcomes using local bone graft versus iliac graft for subtalar distraction arthrodesis in patients with calcaneal malunion. In addition, using local bone graft negates the donor site morbidity.

Aims

Infected and deformed neuropathic feet and ankles are serious challenges for surgical management. In this study we present our experience in performing ankle arthrodesis in a closed manner, without surgical preparation of the joint surfaces by cartilaginous debridement, but instead using an Ilizarov ring fixator (IRF) for deformity correction and facilitating fusion, in arthritic neuropathic ankles with associated osteomyelitis.

Aims

Tibiotalocalcaneal (TTC) fusion is used to treat a variety of conditions affecting the ankle and subtalar joint, including osteoarthritis (OA), Charcot arthropathy, avascular necrosis (AVN) of the talus, failed total ankle arthroplasty, and severe deformity. The prevalence of postoperative complications remains high due to the complexity of hindfoot disease seen in these patients. The aim of this study was to analyze the relationship between preoperative conditions and postoperative complications in order to predict the outcome following primary TTC fusion.
