Described techniques aimed at restoring the normal anatomy of the calcaneus have mostly been focused on percutaneous methods, which are not without complication. Described in this report is a method of anatomic reduction during open reduction and internal fixation of these injuries, which uses a lamina spreader to simultaneously reduce calcaneal varus, restore calcaneal height, reduce the subtalar joint, and restore normal calcaneal width. Additionally, 6 patients with 7 calcaneal fractures were identified that underwent this technique, and radiographic review was performed. Varus deformity of the calcaneus was measured as 93.8 ± 4.3° (range 88.1° to 100.5°) preoperatively and 83.3 ± 3.7° (range 77.8° to 89.4°) postoperatively, with a mean difference of 10.9 ± 5.6° (range 1.3° to 17.3°; P = .0564).

Orr","doi":"10.1177/1938640016676340","DOIUrl":"https://doi.org/10.1177/1938640016676340","url":null,"abstract":"Introduction. Historically, Achilles tendon repairs and other surgeries about the hindfoot have demonstrated a significantly higher rate of wound healing complications and surgical site morbidity. The purpose of this study was to evaluate the comprehensive complication profile and risk factors for adverse short-term, clinical outcomes after primary repair of Achilles tendon ruptures. Methods. Between the years 2005 and 2014, all cases of primary Achilles tendon repair (Current Procedural Terminology code 27650) entered into the National Surgical Quality Improvement Project (NSQIP) database were extracted for analysis. Primary outcomes of interest were rates of total complication, reoperation, and rerupture within 30 days of index surgery. Independent risk factors associated with these selected endpoints were assessed with chi-square and logistic regression analysis and odds ratios with 95% confidence intervals were used to express relative risk. Results. Of 1626 patients with an average age of 44 years (SD 13.3), the average ASA classification was 1.69 and hypertension (20.7%), morbid obesity (8.3%), and diabetes (4.9%) were among the most common medical comorbidities. A total of 28 (1.7%) patients sustained perioperative complications, including 1.3% with local complications (0.7% superficial wound infection, 0.4% wound disruption) and no cases of peripheral nerve injury or early repair failure. Systemic complications occurred in 0.4%, most commonly with deep venous thrombosis or nonfatal thromboembolism. Preoperative albumin was independently associated with an increased risk of local wound complications (odds ratio [OR] 28.67; 95% CI 1.42-579.40; P = .029). Chronic obstructive pulmonary disease (OR 22.33, 95% CI 2.49-199.81; P = .006) and bleeding disorder (OR 14.83, 95% CI 1.70-129.50; P = .015) were more likely to result in a systemic complication, and preoperative creatinine correlated with an increased risk of any complication (OR 6.11, 95% CI 1.15-32.34; P = .033). In total there were 5 (0.3%) readmissions with 2 (0.1%) unplanned reoperations attributed to local wound complications. Conclusion. Among a broad-based demographic of the United States, the rate of local wound complications was exceedingly low in the short-term perioperative period, although this risk may be significantly magnified with subtle decreases in albumin levels. Preoperative risk stratifications should carefully scrutinize for subtle abnormalities in nutritional parameters and renal function prior to undergoing Achilles surgery.

Total ankle arthroplasty (TAA) provides an alternative to ankle fusion (AF). The purpose of this study is to (1) determine the extent of TAA regionalization, as well as examine the growth of TAA performed at high-, medium-, and low-volume New York State institutions and (2) compare this regionalization and growth with AF. Methods. The New York Statewide Planning and Research Cooperative System (SPARCS) administrative data were used to identify 737 primary TAA and 7453 AF from 2005 to 2014. The volume of TAA and AF surgery in New York State was mapped according to patient and hospital 3-digit zip code. Results. The number of TAA per year grew 1500% (from 11 to 177) from 2005 to 2014, while there was a 35.6% reduction (from 895 to 576) in yearly AF procedures. TAA recipients were widely distributed throughout the state, while TAA procedures were regionalized to a few select metropolitan centers. AF procedures were performed more uniformly than TAA. The number of TAA has continued to increase at high- (15 to 91) and medium-volume (14 to 67) institutions where it has decreased at low-volume institutions (44 to 19). Conclusion. The increased utilization of TAA is attributed to relatively few high-volume centers located in major metropolitan centers.

Recent studies have focused on comparing various constructs for this procedure both in the laboratory and clinical settings. The current study compared in a cadaveric model the strength of 2 constructs. The first construct utilized a medially applied low-profile locking plate and an interfragmentary screw directed from plantar-distal to dorsal-proximal. The second construct consisted of a plantarly applied plate with a compression screw placed through the plate from plantar-distal to dorsal-proximal. The ultimate load to failure for the 2 groups tested was 255.38 ± 155.38 N and 197.48 ± 108.61 N, respectively (P = .402). There was no significant difference found between the 2 groups with respect to ultimate load to failure, stiffness of the construct, or moment at time of failure. In conclusion, the medially applied plate with plantar interfragmentary screw appears to be stronger than the plantar Lapidus plate tested for first metatarsal cuneiform arthrodesis, though this difference did not reach statistical significance.

Although Eichenholtz and the Schon systems are commonly used to evaluate foot Charcot arthropathy on radiographs, a novel system with expanded characterization may have added benefit. Methods. Patients with Charcot arthropathy and foot radiographs were grouped in nonsurgical group 1 (imaging sets at minimum 2-year interval) and surgical group 2 (imaging preceding fusion and/or amputation). Radiographs were scored with Eichenholtz and Schon systems, and a novel scoring system (summation of 0-3 rank for bone density, distention/swelling, debris, disorganization, and dislocation/subluxation). Summative scores of the 2 groups were compared. Differences in scores of each system from serial images of group 1 were compared and average scores from each of the systems for preoperative imaging sets of group 2 were compared. Results. A total of 111 patients were included (group 1, 19 patients; group 2, 92 patients). The novel system provided a broad numerical characterization of the radiographs (range 1-15). Summative scores of the novel system for groups 1 and 2 were statistically different with lower median score in the nonsurgical group (nonsurgical median score 6 vs surgical median score 9). Individual characteristic scores from 4 (distention, debris, disorganization, and dislocation) of 5 categories for the novel system were statistically different, with lower scores for the nonoperative group. The narrower numerical scores from the Eichenholtz and Schon systems did not yield statistically significant results. Conclusion. The novel scoring system provides a broad numerical description of radiographic findings in Charcot arthropathy of the foot and has potential advantage for surgical predictive value.

While trans-syndesmotic fixation with metal screws is considered the gold standard in treating syndesmotic injuries, controversy exists regarding the need and timing of postoperative screw removal. Formal recommendations have not been well established in the literature and clinical practice is highly variable in this regard. The purpose of this systematic review is to critically examine the most recent literature regarding syndesmotic screw removal in order to provide surgeons an evidence-based approach to management of these injuries. Methods. The Cochrane Library and PubMed Medline databases were explored using search terms for syndesmosis and screw removal between October 1, 2010 and June 1, 2016. Results. A total of 9 studies (1 randomized controlled trial and 8 retrospective cohort studies) were found that described the outcomes of either retained or removed syndesmotic screws. Overall, there was no difference in functional, clinical or radiographic outcomes in patients who had their syndesmotic screw removed. There was a higher likelihood of recurrent syndesmotic diastasis when screws were removed between 6 and 8 weeks. There was a higher rate of postoperative infections when syndesmotic screws were removed without administering preoperative antibiotics. Conclusion. Removal of syndesmotic screws is advisable mainly in cases of patient complaints related to the other implanted perimalleolar hardware or malreduction of the syndesmosis after at least 8 weeks postoperatively. Broken or loose screws should not be removed routinely unless causing symptoms. Antibiotic prophylaxis is recommended on removal. Radiographs should be routinely obtained immediately prior to removal and formal discussions should be had with patients prior to surgery to discuss management options if a broken screw is unexpectedly encountered intraoperatively. Radiographs and/or computed tomography imaging should be obtained after syndesmotic screw removal when indicated for known syndesmotic malreduction.

Structural fresh osteochondral allograft transfer is an appropriate treatment option for large osteochondral lesions of the talus (OLTs), specifically lesions involving the shoulder of the talus. Sparse literature exists regarding functional outcome following this surgery in high-demand populations. Materials and Methods. Over a 2-year period, a single surgeon performed 8 structural allograft transfers for treatment of large OLTs in an active duty US military population. Lesion morphology and magnetic resonance imaging (MRI) stage were recorded. Preoperative and latest postoperative American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot-ankle and pain visual analog scores were compared. Results. Eight male service members with mean age 34.4 years underwent structural allograft transfer for OLTs with mean MRI stage of 4.9 and a mean lesion volume of 2247.1 mm3. Preoperative mean AOFAS hindfoot-ankle score was 49.6, and mean pain visual analog score was 6.9. At mean follow-up of 28.5 months, postoperative mean AOFAS score was 73, and mean pain visual analog score was 4.5, representing overall improvements of 47% and 35%, respectively. Three patients were considered treatment failures secondary to continued ankle disability (2) or graft resorption requiring ankle arthrodesis. Conclusions. Despite modest improvements in short-term functional outcome scores, large osteochondral lesions requiring structural allograft transfer remain difficult to treat, particularly in high-demand patient populations. Surgeons should counsel patients preoperatively on realistic expectations for return to function following structural allograft transfer procedures.
