Contact areas and peak pressures in the posterior facet of the subtalar and the talonavicular joints were measured in cadaver lower limbs for both the normal limb and after fixation of the tibiotalar joint. Six joints were fixed in neutral, in 5–7° of varus and of valgus. Ten degrees of equinus angulation was also studied. Each position of fixation was tested independently. Neutral was defined as fixation without coronal or sagittal plane angulation compared with prefixation alignment of the specimen. When compared with normal unfused condition, peak pressures increased, and contact areas decreased in the subtalar joint for specimens fixed in neutral, varus, and valgus. However, the change in peak pressure for neutral fusion compared with normal control was not statistically significant ( P > 0.07). Peak pressures for varus and valgus fixation were significantly different from normal ( P < 0.001). Contact areas for all positions of fixation were significantly different from normal ( P < 0.001). Coronal plane angulation, however, also resulted in significantly lower contact areas compared with neutral fixation ( P < 0.001). Contact areas and peak pressures in the talonavicular joint did not appear to be substantially affected by tibiotalar fixation with coronal plane angulation. Equinus fixation qualitatively increased contact areas and peak pressures in the talonavicular and posterior facet of the subtalar joint. Neutral alignment of the tibiotalar joint in the coronal and sagittal planes altered subtalar and talonavicular joint contact characteristics the least compared with normal controls. Therefore, ankle fusion in the neutral position would be expected to most closely preserve normal joint biomechanics and may limit the progression of degenerative arthrosis of the subtalar joint.

ABSTRACT Lateral swivel dislocation, a subtype pattern of dislocations occurring at mid tarsal joint is a rare type of injury. A medially or laterally directed force applied to the forefoot causes dislocation of the talonavicular joint but not subtalar joint. The calcaneum alongwith the remaining foot swivels on the intact interosseous talocalcaneal ligament. The present case report is a more rare lateral swivel type of dislocation of talonavicular joint in a 25-year-old male. The article also presents a comprehensive review of literature and management of such type of injuries of the hindfoot . How to cite this article Kapila R, Verka Ps, Garg Rs, Ahmed M.

Joint Range

Lengthening the lateral column of the foot has been shown to correct flatfoot deformity. In adults, however, lengthening leads to calcaneocuboid arthritis. Lateral column lengthening with calcaneocuboid fusion, which lengthens the lateral column of the foot and prevents calcaneocuboid arthritis, was investigated in a cadaver model to determine the remaining range of motion in the talonavicular and subtalar joints. Inversion/eversion motion was produced by tendon pulls and the range of motion was measured in three dimensions using a magnetic space tracker. After lateral column lengthening with calcaneocuboid fusion, 48% of talonavicular and 70% of subtalar joint range of motion were preserved. Analysis of the inversion and eversion ranges of motion suggests that the lengthening fusion limits eversion more than inversion. These findings demonstrate the need for clinical investigation of this procedure, which could preserve motion in the talonavicular and subtalar joints, correct deformity, and obviate calcaneocuboid arthritis.

Important Sign

Recommendation: Progressive collapsing foot deformity (PCFD) is a complex 3D deformity with varying degrees of hindfoot valgus, forefoot abduction, and midfoot supination. Although a medial displacement calcaneal osteotomy can correct heel valgus, it has far less ability to correct forefoot abduction. More severe forefoot abduction, most frequently measured preoperatively by assessing talonavicular coverage on an anteroposterior (AP) weightbearing conventional radiographic view of the foot, can be more effectively corrected with a lateral column lengthening procedure than by other osteotomies in the foot. Care must be taken intraoperatively to not overcorrect the deformity by restricting passive eversion of the subtalar joint or causing adduction at the talonavicular joint on simulated AP weightbearing fluoroscopic imaging. Overcorrection can lead to lateral column overload with persistent lateral midfoot pain. The typical amount of lengthening of the lateral column is between 5 and 10 mm. Level of Evidence: Level V, consensus, expert opinion. CONSENSUS STATEMENT ONE: Lateral column lengthening (LCL) procedure is recommended when the amount of talonavicular joint uncoverage is above 40%. The amount of lengthening needed in the lateral column should be judged intraoperatively by the amount of correction of the uncoverage and by adequate residual passive eversion range of motion of the subtalar joint. Delegate vote: agree, 78% (7/9); disagree, 11% (1/9); abstain, 11% (1/9). (Strong consensus) CONSENSUS STATEMENT TWO: When titrating the amount of correction of abduction deformity intraoperatively, the presence of adduction at the talonavicular joint on simulated weightbearing fluoroscopic imaging is an important sign of hypercorrection and higher risk for lateral column overload. Delegate vote: agree, 100% (9/9); disagree, 0%; abstain, 0%. (Unanimous, strongest consensus) CONSENSUS STATEMENT THREE: The typical range for performing a lateral column lengthening is between 5 and 10 mm to achieve an adequate amount of talonavicular coverage. Delegate vote: agree, 100% (9/9); disagree, 0%; abstain, 0%. (Unanimous, strongest consensus)

Category: Ankle, Ankle Arthritis, Hindfoot, Midfoot/Forefoot Introduction/Purpose: Patients with arthritis or severe dysfunction involving both the ankle and the subtalar joints can benefit tibiotalocalcaneal (TTC) arthrodesis or total ankle replacement and subtalar fusion. With the evolution of prosthetic design and surgical techniques, total ankle replacement (TAR) has become a reasonable alternative to arthrodesis. The aim of this study was to investigate the fusion rate of the subtalar joint and talonavicular joint in patients simultaneously treated with total ankle replacement (TAR) and subtalar joint fusion. Methods: This study includes 11 patients who underwent primary TAR and simultaneous subtalar and talonavicular fusion from May 2011 to January 2015. Six males and five females were enrolled with a mean age of 61 years (41-75). Patients were clinically assessed preoperatively and at 6 and 12 months postoperatively. Total follow-up time was 24.2±11.6 months. Radiographic examination included a postoperative CT scan obtained 12 months after surgery. Three surgeons independently reviewed the CT scans and interobserver reliability was calculated. Functional scores were also assessed. Results: At 12 months postoperatively, the subtalar fusion rate in patients treated with TAR and simultaneous subtalar fusion was 92% and the talonavicular fusion rate was 88%. There was a statistically significant increase in American Orthopedic Foot & Ankle Society ankle/hindfoot score from 25.9 to 74.1 at 12 months post-operatively. Ankle range of motion significantly increased from 10.2° to 30.8 degrees. Additionally, there was a statistically significant decrease in visual analog scale (VAS) pain score from 8.8 to 1.9. Conclusion: TAR and simultaneous subtalar and talonavicular joint fusion are reliable procedures for the treatment of ankle and subtalar joint arthritis. Furthermore, CT scans showed an excellent reliability among orthopaedic surgeons in determining the degree of successful fusion of subtalar and talonavicular arthrodesis.

The Difference

Category: Pathophysiology Introduction/Purpose: Gastrocnemius eqiunus has been associated with a wide range of foot and ankle pathologies in the literature, however, many still question it’s involvement or existence. A recent response in Foot & Ankle International pointed out an incorrect demonstration of the Silfverskold test in a prior study. With a growing body of literature supporting gastrocnemius equinus as a contributing factor in foot and ankle pain, why do many feel that it still does not exist? It was our hypothesis that unless the examination is performed correctly, the diagnosis can be missed and could be the potential cause for disbelief in its existence or effect on foot and ankle pain. We sought to demonstrate the difference in examination findings when performing the test correctly and incorrectly. Methods: Thirty consecutive patients with conditions associated with gastrocnemius equinus in the literature were included in the study. Each patient was consented and had a Silverskold test performed correctly by inverting and locking the subtalar joint as well as stabilizing the talonavicular joint in order to isolate the ankle joint. We then performed the exam incorrectly without stabilizing the same two joints, allowing motion through the ipsilateral hindfoot and midfoot joints. A long arm goniometer was used to measure the angles with each arm along the length of the fibula and fifth metatarsal. The senior author performed all of the examinations to maintain consistency. The angles were recorded for later review. Results: We found that when the subtalar and talonavicular joints were stabilized, there was almost fifteen degrees less dorsiflexion than when the same joints were not stabilized. The average dorsiflexion when performed in the correct manner was seventy-eight degrees, while the average dorsiflexion with the exam performed incorrectly was ninety-three degrees. Conclusion: We demonstrated that if the examination is not performed correctly, the equinus contracture could go undiagnosed as motion through the hindfoot and midfoot joints can alter the findings. It is important to understand and perform the technique correctly to evaluate for the contracture as it has been shown to be a contributing factor in many foot and ankle problems. If we standardize the examination, there may be less disagreement about its existence or affect on foot and ankle pain.

A case of bilateral accessory calcanii is presented in which the accessory ossicle articulated with the talus and calcaneus at the lateral aspect of the posterior facet of the subtalar joint, causing premature subtalar degenerative changes in a 19-year-old man. Although rare and usually asymptomatic, accessory ossicles around the foot may need surgical excision if painful or if sufficient size is obtained to cause deformity and/or limitations in range of motion.

The Difference

The cervical ligament plays a significant role in lateral stability of the subtalar joint but has received little attention compared with other ankle and subtalar joint ligaments. The purpose of this research was twofold. First, the elongation behavior of the cervical ligament was assessed with the calcaneofibular ligament intact and cut during two different types of inversion loads (manual and mechanical). Second, inversion range of motion was determined concomitantly with inversion loading and the difference in inversion range of motion between the calcaneofibular ligament intact to cut state was compared. The mean elongation of the cervical ligament with the calcaneofibular intact was 0.58 mm (± 0.33 mm) and 0.46 mm (± 0.23 mm) for manual and mechanical methods, respectively, and 0.88 mm (± 0.37 mm) and 0.78 mm (± 0.37 mm), respectively, for the same methods in the absence of the calcaneofibular ligament. This difference was statistically significant ( P < 0.05 manually and P < 0.02 mechanically). An average increase in the inversion range of motion was noted with both methods [7.5° manually (± 2.75°) and 7.7° mechanically (± 2.95°)] after lesioning of the calcaneofibular ligament. This difference was statistically significant ( P < 0.001) for both manual and mechanical range of motion testing. The results of this study indicate that there is a significant increase in elongation of the cervical ligament in the absence of the calcaneofibular ligament during manual and mechanically applied inversion loads in a open kinetic chain. Clinical and theoretical implications of this data are discussed.

High School Football

Tarsal coalition is a bony or fibrous bridge between 2 tarsal bones. The condition is typically congenital and presents in early to mid-adolescence. Common symptoms include ankle pain, stiffness, and limited range of motion. Conservative treatment of tarsal coalition consists of immobilization, short leg walking cast, steroid injections, physical therapy, ankle braces, and orthotics. When conservative care fails, surgical intervention for tarsal coalition includes excision of the coalition or joint arthrodesis. We present a case of a high school football player with a 5-year history of left ankle pain secondary to a talocalcaneal coalition. The athlete did not respond favorably to conservative treatment and underwent a subtalar joint arthrodesis. Prior to surgery, the athlete consented to self-reported functional outcome measures, range of motion measures, and 3D video gait analysis to evaluate the effects of surgery. Measurements were taken prior to surgery and 1½ years after surgery. Clinically significant improvements were seen in subjective outcome measures and functional ankle range of motion in this case. There is limited research available to validate long-term outcomes for current conservative and surgical treatments of tarsal coalition. In this case, joint arthrodesis resulted in a good long-term outcome for this athlete. Levels of Evidence: Therapeutic, Level IV: Case study
