Objective: To summarize the effectiveness of limited orthopedic surgery combined with external fixation for the treatment of lower extremity sequelae of middle and old aged post-poliomyelitis, and then to explore the strategy of surgical correction and functional reconstruction method.

Methods: From the database of 23 310 cases of poliomyelitis sequelae treated by QIN Sihe Orthopaedic Surgical team between September 1982 and December 2017, 629 patients over 41 years old were retrieved and the epidemiological characteristics of the patients were analyzed. Between March 2011 and June 2015, 57 patients with poliomyelitis sequelae treated with limited operation and external fixation were followed up 2-6 years, and the history of poliomyelitis sequelae was 41-67 years (mean, 47.

Posterior tibial tendon dysfunction (PTTD) is a progressive disorder secondary to advanced degeneration of the posterior tibial tendon, leading to the abduction of the forefoot, valgus rotation of the hindfoot, and collapse of the medial longitudinal arch. Eventually, the disease becomes so advanced that it begins to affect the deltoid ligament over time. This attenuation and eventual tear of the deltoid ligament leads to valgus deformity of the ankle.

Background: Delayed union and nonunion following foot and ankle arthrodesis is a disabling complication for patients. There are no clinical studies looking at whether there is a role for use of low-intensity pulsed ultrasound (LIPUS) following this. The aim of this study is to investigate the efficacy of LIPUS in this cohort of patients in our centre. Read More

Rigid flatfoot deformity is a debilitating condition that can be managed by triple arthrodesis surgery. Triple arthrodesis has the potential to restore health-related quality of life, but it is also associated with several complications. Few studies have examined the 30-day readmission rates after triple arthrodesis. Read More

Foot and ankle surgeons continue to explore bone graft alternatives that will be comparable to the reference standard of autologous bone. The purpose of the present study was to consider the outcomes of hindfoot arthrodesis supplemented with bioactive glass in patients at risk of delayed union and nonunion. We performed a retrospective radiographic review of 29 consecutive patients (48 joints) who had undergone arthrodesis of ≥1 joint of the hindfoot (ankle, subtalar, talonavicular, calcaneocuboid).

The contemporary literature is unclear regarding the joint that is most "at risk" to yield a nonunion in the performance of triple arthrodesis of the foot. There is also a debate regarding the best methods of joint preparation. A retrospective radiographic review was conducted of all primary triple arthrodeses performed within in a Northern California health maintenance organization between January 2007 and June 2013.

Surgical access to the subtalar joint is required in a plethora of pathologic conditions of the hindfoot. The conventional lateral approach can give excellent access to subtalar joint; however, in hindfoot valgus deformities, there can be unacceptable risks of wound problems and incomplete deformity corrections. The medial approach offers good access to the subtalar joint with an increasing evidence base for its use, especially with double fusions in pes planus deformities. Read More

Aim/purpose: Extreme congenital club foot deformities are common in developing countries, presenting at birth, persisting in children, adolescents and adults; as untreated/under-corrected by conservative and/or surgical means. Scores of confusing names exist in literature for such deformities with no good treatment available; mostly advocating unacceptable arthrodesis. The author researched this grey area for more than 40 years and successfully innovated improved surgical corrections, more acceptable to patients. Read More

Background And Purpose: Qualitative analysis has its limitations as the speed of human movement often occurs more quickly than can be comprehended. Digital video allows for frame-by-frame analysis, and therefore likely more effective interventions for gait dysfunction. Although the use of digital video outside laboratory settings, just a decade ago, was challenging due to cost and time constraints, rapid use of smartphones and software applications has made this technology much more practical for clinical usage.

Orthopedic complications of intravenous (IV) infiltration are rare, with only a handful of cases reported in the literature. Because of the relatively high rate of IV infiltration in neonates, however, such complications do occur and can include growth arrest, limb length discrepancy, and joint deformities that require surgical intervention. The risk of these complications is highest in preterm neonates. Read More

In symptomatic patients, undercorrection of a flatfoot deformity can lead to the need for revision surgery to restore functional mechanics and prevent progression of deformity. The underlying cause of undercorrection is failure to fully recognize or understand the extent of the deformity.

Deltoid ligament reconstruction allows for joint preservation of the ankle in the setting of patients a triple arthrodesis due to a flat foot deformity. Although the increased forces that may occur in the ankle joint after a triple arthrodesis cannot be eliminated, reconstruction of the ligament will delay and may prevent the onset arthritis, allowing the patient to maintain mobility of the ankle joint. The anatomy, surgery, and risks and benefits are discussed. Read More

Delayed identification of patients requiring admission to extended care facilities (ECFs) can lead to greater healthcare costs through an increased length of hospital stay (LOHS).

Triple (talonavicular, subtalar, and calcaneocuboid) joint arthrodesis and most recently double (talonavicular and subtalar) joint arthrodesis have been well proposed in the literature for surgical repair of the elective, posttraumatic, and/or neuropathic hindfoot deformities. The articulation of the hindfoot with the ankle and midfoot is multiaxial, and arthrodesis of these joints can significantly alter the lower extremity biomechanical manifestations by providing anatomic correction and alignment. This article reviews the indications and preoperative planning for some of the most common procedures to address the hindfoot deformity. Read More

For rigid pes planovalgus deformities, modified double and triple arthrodeses have had high union rates and subjective outcomes reported. Increased rates of talonavicular nonunions after modified double arthrodesis have led to concern regarding this procedure.

However, after ankle replacement, it is unknown how hindfoot biomechanics and blood supply may be affected. Consequently, subsequent hindfoot joint fusion may be adversely affected. Read More

Background: While successful subtalar joint arthrodesis provides pain relief, resultant alterations in ankle biomechanics need to be considered, as this procedure may predispose the remaining hindfoot and tibiotalar joint to accelerated degenerative changes. However, the biomechanical consequences of isolated subtalar joint arthrodesis and additive fusions of the Chopart's joints on tibiotalar joint biomechanics remain poorly understood.

Questions/purposes: We asked: What is the effect of isolated subtalar fusion and sequential Chopart's joint fusions of the talonavicular and calcaneocuboid joints on tibiotalar joint (1) mechanics and (2) kinematics during loading for neutral, inverted, and everted orientations of the foot?

Methods: We evaluated the total force, contact area, and the magnitude and distribution of the contact stress on the articular surface of the talar dome, while simultaneously tracking the position of the talus relative to the tibia during loading in seven fresh-frozen cadaver feet. Read More

Methods: Seventy-nine osteoporotic patients with single-level degenerative spondylolisthesis were randomly assigned to receive either zoledronic acid infusion (zoledronic acid group) or saline infusion (controls) after spinal fusion. Read More

Introduction: In geriatric patients the management of odontoid type II fractures is complicated by osteoporosis and atlantoaxial arthritis (spondylarthritis C1/C2) with an increased lever arm. Furthermore, a few of the odontoid fractures are accompanied by an atlas fracture resulting in the "atlantoaxial unhappy triad". Posterior C1/C2 spondylodesis with bilateral Magerl screws and C1 hooks is a strong biomechanical construct, however, the posterior approach is associated with several drawbacks such as increased risk of infection and increased blood loss.
