Calcaneal Lengthening

Abstract Background Evans calcaneal lengthening osteotomy is used to treat symptomatic flexible flatfoot when conservative treatment fails. Grafts such as autologous iliac bone grafts, allografts, and xenografts are implanted at the osteotomy site to lengthen the lateral column of the hindfoot. This study aimed to present the outcomes of an autologous mid-fibula bone graft used for calcaneal lengthening in symptomatic pes valgus in adolescents. Methods We retrospectively examined 23 ft of 13 adolescents who underwent surgery between July 2014 and January 2018. The radiological and clinical outcomes (American Orthopaedic Foot and Ankle Society ankle-hindfoot scale scores) were assessed during a mean follow-up of 49.7 (range, 30.9–73.4) months. The mean distance of the lengthening site was measured to evaluate graft sinking or collapse. The Goldberg scoring system was used to determine the degree of union at the donor and recipient sites. Results The calcaneal pitch and the anteroposterior and lateral talo-first metatarsal (Meary) angles showed significant correction, from 14.4 to 19.6 (p < 0.001), and from 14.5 to 4.6 (p < 0.001) and 13.5 to 8.5 (p < 0.001), respectively. The mean distance of the lengthening site showed no significant change (p = 0.203), suggesting no graft sinking or postoperative collapse. The lateral distal tibial angle showed no significant difference (p = 0.398), suggesting no postoperative ankle valgus changes. Healing of the recipient and donor sites occurred in 23 and 21 ft, respectively. The American Orthopaedic Foot and Ankle Society ankle-hindfoot scores improved significantly, from 68.0 to 98.5 (p < 0.001). Conclusions Evans calcaneal lengthening using an ipsilateral mid-fibula bone autograft resulted in significant improvement in clinical and radiological outcomes without ankle valgus deformity. Hence, it could be a treatment option for lateral column calcaneal lengthening in adolescents.

Category: Hindfoot Introduction/Purpose: An adult acquired flat foot (AAFD) is a complex 3D deformity. A medializing calcaneal osteotomy (MCO) is a surgical procedure frequently performed to correct the valgus alignment of the hindfoot in a stage II AAFD, when conservative measurements fail. However currently little is known on its accurate influence regarding the hindfoot alignment (HA). The aim is therefore to assess the influence of a MCO on the 3D HA using computer aided software analysis of the images retrieved from a weightbearing cone beam CT (WBCT). Methods: Twelve patients with a mean age of 49,4 years (range 18-67yrs) were prospectively included in a pre-post study design. Indications for surgical correction by a MCO with a solitary translation consisted of an AAFD stage II (N=10) and a posttraumatic valgus deformity (N=2). Fixation of the osteotomy was performed by a step-plate or double screw. WBCT was obtained pre- and post-operative. Images were subsequently segmented to allow a HA calculation in 3D(HA3D) by an angle between the anatomical tibia axis and the axis connecting the computed inferior calcaneuspoint and the centroid of the talus in the coronal plane based on a Cartesian coordinatesystem(Fig 1A, C). The tibia in the HA3D was separately assessed by the anatomical tibia axis (TAx 3D) and the axis to determine the tibial rotation(TR 3D) in the axial plane by connecting the computed most outer point of the anterior and posterior tubercle of the incisura fibularis(Fig 2A, D). Results: The mean medial translation of the calcaneal osteotomy during surgery was 5.72 mm (SD = 3.9). The mean HA3D pre-operatively equaled 18.21 degrees of valgus (SD = 6.6) and post-operatively 9.31 degrees of valgus (SD = 6.18). The Paired Student’s t-test showed a significant correction of 8.89 degrees (95%CI [5.99, 11.80], P<0.001). The mean TAX 3D pre-operatively was 6.80 degrees of valgus (SD = 3.38) and post-operatively 4.11 degrees of valgus (SD = 2.77), with a significant difference of 2.69 degrees (95%CI [1.79, 3.59], P <0.001). The mean TR3D pre-operatively was -27.11 degrees (SD = 4.77) and post-operatively - 28.80 degrees (SD = 5.98) and showed a significant difference of 1.69 degrees (95%CI [0.41, 2.97], P = 0,016). Conclusion: This study shows an effective correction of the valgus hindfoot in an AAFD. It appears that the correction is not only situated in the calcaneus but also to a lesser extent in the tibia and this resulted in 15% of the achieved HA correction. The novelty is the 3D weightbearing assessment of a hindfoot correction and the shown influence on the tibia. This information could be of use to take in to account when performing a pre-operative planning of a hindfoot deformity.

Category: Ankle Introduction/Purpose: To explore the effectiveness and operative methods to treat various mal-united Pilon fractures with joint-sparing osteotomy. Methods: Between January 2011 and October 2016, 21 patients with mal-united Pilon fractures were treated with joint-sparing osteotomy. There were 13 males and 8 females with an average age of 38.4 years (range, 22-48 years). 14 were left feet and 7, right. The time from injury to reconstructive operation was 4 months to 10 years. 17 received operative treatment previously, and 4 were treated by plaster fixation. According to Rüedi-Allgöwer classification, 16 were rated as type II (including 6 medial Pilon fractures, 5 anterior, 5 posterior) and 5, type III. All patients received standardized postoperative managements. Results: All patients were followed up for more than 1 year. All the fractures were reunited in an average time of 13.8 weeks (range 9 to 18 weeks). The mean visual analogue scale (VAS) score was 2.42 (range 0 to 5) and the mean ankle and hindfoot scale of the American Orthopaedic Foot and Ankle Society (AOFAS) score was 78.81(range 65 to 92) 6 months after operation. The VAS score was 5.27 (range 2 to 7) and the AOFAS score was 57.26 (range 20 to 81) before. Comparing to preoperative data, statistically significant difference was found postoperatively (P<0.05). Conclusion: Results by joint-sparing osteotomy to realign and reconstruct articular surfaces of ankles are acceptable. Functions and symptoms are improved significantly after operation. Joint-sparing osteotomy can be a considerable option for treating mal-united Pilon fractures.

We have used an extensor hallucis brevis tenodesis procedure to treat symptomatic hallux varus in six patients (five women and one man). Indications for this procedure include the presence of flexible metatarsophalangeal and interphalangeal joints and the absence of arthritis. In this group (mean age, 47 years; range, 18–65 years), hallux varus followed correction of hallux valgus deformity in five patients and traumatic dislocation of the hallux in one patient. Excellent correction was noted and maintained in all patients at a mean interval of 28 months (range, 24–32 months) after surgery. Despite a slight decrease in dorsiflexion following surgery (average, 10°), there were no additional complications noted, and the mean American Orthopaedic Foot and Ankle Society rating score improved from 61 to 85 after surgery.

Objective: The objective of this study was to perform a functional evaluation of diabetic patients with plantar ulcers using the American Orthopaedic Foot and Ankle Society (AOFAS) score. Methods: In this prospective cohort study, 50 diabetic patients treated in an outpatient clinic under conservative management were consecutively evaluated for active ulcers on the foot. The ulcer mean progression time, size and classification and the AOFAS score were evaluated. Results: Among the sample, 38 (76%) were men, the mean age was 64 years, and the mean body mass index was 28.27 kg/m2. The mean ulcer progression time was 9 months, and 40 (80%) patients were classified as Wagner grade 1. There was a significant difference in AOFAS scoresbetween ulcer grades. Conclusion: The AOFAS score can be used for functional evaluation in diabetic patients with ulcers. However, due to the peculiarities of this population, it is important to search for new and more comprehensive evaluation instruments. Level of Evidence II; Prognostic Studies; Prospective Study.

Objective: To demonstrate the efficacy of locking plate osteosynthesis performed by an L-shaped lateral approach in patients with Sanders type III and IV intra-articular calcaneal fractures with posterior facet displacement. Methods: Fifty-three patients with Sanders type III or IV unilateral calcaneal fractures treated with locking plates and additional bone grafting were included in the study. Böhler and Gissane angles, and heel height values were measured on the radiological examinations. Clinical results of the patients were evaluated using the American Orthopaedic Foot and Ankle Society and Maryland evaluation criteria. The presence of arthrosis was investigated with Broden’s view. Preoperative and postoperative values were evaluated. Results: The mean Gissane angle was 119.32°, the mean Böhler angle was 9.47° and the mean heel height was 40.82 mm on radiographs at initial presentation of the patients. The mean Gissane angle was 114.63°, the mean Böhler angle was 23.33° and the mean heel height was 47.84 mm on the early postoperative radiographs of the patients. In patients, a mean 4.69° recovery was achieved in the Gissane angle, 13.86° in Böhler angle and 7.02 mm in heel height. On the most recent follow-up, Böhler angle was 21.49°, Gissane was 114.88° and the mean heel height was 46.95 mm. The mean American Orthopaedic Foot and Ankle Society score and Maryland score were 86.91 and 86.53, respectively, on the last follow-up. Conclusion: Internal fixation and grephonage using low-profile locking plates provides good functional results to patients since it facilitates anatomic restoration of the subtalar joint and correction of calcaneal height, width and varus/valgus heel.

The Relationship

To better understand the bony component of pes planus and the means by which the Evans calcaneal lengthening corrects them, we studied the standing radiographs of seven adult patients who had undergone calcaneal lengthening to treat symptomatic pes planus. Weightbearing AP and lateral views done preoperatively and postoperatively were used for the study. For each set of films, the following parameters were measured: on the lateral view; overall length of the calcaneus, lateral talometatarsal angle, lateral talocalcaneal angle, and the calcaneal pitch angle; and on the dorsoplanar view, the talometatarsal and talocalcaneal angle. In addition, the relative coverage of the talus by the navicular was described by an angular measurement based on the relationship of the center of the talus to the center of the navicular. The average improvements in lateral talocalcaneal angle (a reflection of hind-foot valgus) was 6.4° when the long axis of the calcaneus was used and 6.8° when the inferior surface of the calcaneus was used for the measurement. The lateral talometatarsal angle improved an average 11.3° (from an average of 19.7° to 8.4°). The dorsoplantar talometatarsal angle (a measure of forefoot adduction/abduction) improved 15.8° (preoperative average 26.8°, postoperative average 11°). The calcaneal pitch angle improved an average 10.8° (preoperative average 3.2°, postoperative average 14°). The relationship between the talus and navicular was defined by an angular measurement based on the center of each articular surface before and after correction using this measurement. An average improvement of 26° occurred in the alignment of these two articular surfaces. This study confirms Evans' belief that significant correction can be obtained by lateral column lengthening, that the relationship between navicular and talus can be restored without fusion, and that the forefoot position corrects without operative intervention to the medial side of the foot. This study also provides numerical guidelines for the surgeon planning surgical correction of symptomatic pes planus, and since bony relationships can be observed before and after correction, some insight may be gained into tarsal morphology of pes planus.

Background: The goal of this study was to identify pressure changes throughout the peroneal groove after a groove deepening procedure. We hypothesized that pressures would decrease. Methods: Twelve fresh-frozen foot and ankle specimens were used. A thin pressure strip containing four sensor pads was secured within the peroneal groove with pads 1 through 4 positioned at the calcaneofibular ligament (CFL) and at the distal, middle, and proximal groove, respectively. The midstance phase of gait was simulated with loads applied to the plantar foot and posterior tibial tendon and to the peroneus longus and brevis tendons. Pressures were recorded with the ankle in neutral, plantarflexion, dorsiflexion, inversion, and eversion. Groove deepening was done by osteotomizing the posterior fibular wall. Pressure readings were then recorded. Average pressures for each of the four sensor pads after the procedure were compared to those obtained before the procedure. Results: The mean pressure overlying the CFL increased at all five ankle positions; however, these changes were not significant. Significant decreases in pressure were noted within the distal and middle groove at all ankle positions after the peroneal groove deepening procedure. Pressure within the proximal groove increased at all but one position, with a significant difference noted in neutral and plantarflexion. Conclusion: Pressures within the middle and distal peroneal groove significantly decreased after a groove deepening procedure. Combining this technique with peroneal tendon debridement may be advantageous for treatment of partial peroneal tendon tears or recalcitrant peroneal tendinitis.

Background This study was performed to determine the factors that influence the clinical outcomes of surgically treated ankle fractures associated with the posterior malleolus (PM). Methods We evaluated 42 fractures of 42 patients. Posterior malleolus fracture size was calculated using computed tomography. Posterior malleolar fractures with a size less than 10% were left nonfixated. The decision for larger fragments was performed using fluoroscopy following the fixation of other components. If the joint was found to be congruent, the PM was left nonfixated. Otherwise, the PM was reduced and fixated. Clinical outcomes were evaluated based on Weber, Freiburg, and American Orthopaedic Foot and Ankle Society scores. Ankle osteoarthritis was determined according to the Canadian Orthopaedic Foot and Ankle Society classification. The effect of PM fixation, age, PM fragment size, waiting period before surgery, presence of ankle dislocation, and number of injured malleoli on clinical outcomes were assessed. Statistical significance was set at a value of P &lt; .05. Results The mean patients age was 48.5 ± 14.9 years (range, 20–84 years) and the mean follow-up was 23.7 ± 8.6 months (range, 12–56 months). Fixation of the PM was performed solely in 12 patients. Postoperative displacement of the PM and articular step were less than 2 mm in all fractures. Statistically significant worse outcomes were demonstrated based on functional scores in the patients with a PM size greater than or equal to 25% (P = .042, P = .038, and P = .048, respectively) and in patients aged 60 years or older (P = .005, P = .007, and P = .018, respectively). However, there was no significant difference between functional scores and the other factors. Ankle osteoarthritis was observed at a higher rate in patients with PM size greater than or equal to 25% and in patients aged 60 years or older. Conclusions Clinical outcomes of the patients are mainly influenced by the patient's age and PM fragment size. However, if the tibiotalar joint is congruent, comparable results can be obtained in PM fixated or nonfixated patients.

Category: Midfoot/Forefoot Introduction/Purpose: To compare the clinical result of midfoot and metatarsal dorsal wedge osteotomy for the treatment of cavovarus foot deformity in adolescents. Methods: A comparative retrospective study of 24 patients with cavovarus foot deformity in adolescents was conducted between March 2012 and March 2015 in the Guangzhou Orthopaedic Hospital. All patients were flexible deformity. 10 patients were treated with midfoot dorsal wedge osteotomy, while 14 patients received metatarsal dorsal wedge osteotomy. The clinical curative effects, complications and image differences were compared between the two groups. American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score and Visual Analogue Scale (VAS) score were evaluated for each patient during the follow-up. All statistics were analyzed using the SPSS software system. Results: No early stage soft tissue complications occurred in all patients. All the patients obtained an average 21.5 months (ranged,10-30 months) follow-up.X-ray demonstrated that bone healing was obtained, the midfoot dorsal wedge osteotomy group at an average of 11.2 weeks (ranged,10-13 weeks). the metatarsal dorsal wedge osteotomy group at an average of 13.4 weeks (ranged,12-15 weeks). By AOFAS foot score and VAS pain score: There is no significant difference between the two groups (P=0.138). No complications of nonunion, recurrence of de-fortuity or implant failure were seen during follow-up. Conclusion: The midfoot and metatarsal dorsal wedge osteotomy are the effective methods for the treatment of cavovarus foot deformity in adolescents. For severe deformity midfoot metatarsal dorsal wedge osteotomy can provide more powerful correction.

Category: Other Introduction/Purpose: Orthopaedic foot and ankle surgery is a young and rapidly evolving orthopaedic subspecialty. Little is known regarding the authors contributing to the field. The purpose of this study is to characterize the demographics of the authors publishing foot and ankle research since the inception of the research journal of the American Orthopaedic Foot and Ankle Society. Methods: All publications in the journal Foot and Ankle International between 1980 and 2017 were reviewed. Papers were characterized in terms of number of authors, number of institutions, and number of references. The first and corresponding authors were also characterized in terms of country of origin, gender, and degree qualification. Each of these characteristics was tested for trends over time. Results: In total, 5,323 publications were reviewed, including 4,297 research articles, 367 case reports, 262 editorials, 159 letters, and 121 technique tips. The mean number of authors per paper increased from 2.3 during the 1980s to 4.3 during the 2010s (p<0.001). The percent of publications with female first authors increased from 4.9% during the 1980s to 13.2% during the 2010s (p<0.001). The country of origin shifted markedly away from the United States during the 1980s towards Europe and other countries during the 2010s (Figure 1). Podiatrists consisted of 1.3% of first authors and 1.4% of corresponding authors—these proportions did not meaningfully change over time (p>0.05). The mean number of references to other work increased from 13.8 during the 1980s to 24.4 during the 2010s (p<0.001). Conclusion: The authors of the foot and ankle literature have changed markedly over the past 4 decades. Most notably, there have been shifts towards female and international authorship. The number of authors per paper has also nearly doubled over time. Such trends are likely to continue as the field of foot and ankle grows.
