Category: Bunion Introduction/Purpose: AOFAS score and angular changes are used widely to assess hallux valgus surgery. But our previous study showed us that these parameters do not reflect patient subjective satisfaction after surgery, angular changes do not correlate with patient satisfaction, and a subjective satisfaction scale must be used. So can we find a measurable parameter that reflects patient satisfaction? The purpose of the study was to evaluate the effect of percental reduction of first web space length (FWSL) on patient satisfaction, and if it can be used as a measurable parameter for this. Methods: Fifty feet of thirty-seven patients were included to the study. All patients were operated between 2010 and 2014. Same surgical technique (Lindgren-Turan osteotomy)used for operations. Patients were evaluated by using hallux valgus angle (HVA),1-2 intermetatarsal angle (IMA), first web space length (FWSL), AOFAS scores. On the final follow-up they were asked to scale their postoperative satisfaction between 1-10;as for 1-2 very unsatisfied, 3-4 unsatisfied, 5-6 neither unsatisfied nor satisfied, 7-8 satisfied, 9-10 very satisfied. The percental changes of HVA, IMA, and FWSL were compared with AOFAS score, and satisfaction scales. Results: Average age was 45,50±12,23 (22-68) years. Mean follow-up was 41,68±14,46 (24-68) months. 29 of 50 feet were right side, 21 were left. Preoperative HVAs have been changed from 32,52±5,19 to 11,58±4,70 degrees (p=0,001; p<0,01). Preoperative IMAs have been changed from 15,00±3,56 to 5,75±2,45 degrees (p=0,001; p<0,01). Preoperative AOFAS scores have been changed from 75,04±5,54 to 93,14±6,25 points (p=0,001; p<0,01). Preoperative FWSL changed from 14,5 (10-22) mm to 7,5 (5-14) mm (p=0,001; p<0,01). Postoperative satisfaction scale was 8,60±0,67 (7-10) points. When HVA and IMA percental changes were compared with AOFAS percental changes, they have shown a negative statistical significance according to Spearman’s Correlation Analysis. When AOFAS percental changes have been compared with satisfaction scale, they have shown a positive statistical significance. When FWSL percental changes were compared with AOFAS percental changes and satisfaction scale it has shown a positive statistical significance for both parameters according to Spearman’s Correlation Analysis. Conclusion: According to our results; we believe that the changes of FWSL have an influence on patient satisfaction. It is correlated both with AOFAS, and subjective satisfaction scale. It can be used as a measurable parameter to search for patients satisfaction. Angular changes do not have an influence on patients satisfaction. May be FWSL should also be used for surgical indications?

Category: Ankle Introduction/Purpose: Surgical site infections (SSI) are among the most expensive healthcare-associated infections and result in a substantial psychosocial and financial burden for both patients and the healthcare system. A majority of SSIs are estimated to be preventable. Previous literature has focused on antibiotic prophylaxis as the primary intervention to reduce the incidence of SSI. However, little work in the foot and ankle literature has been done on the characterization and risk stratification of patients who will go on to develop superficial versus deep incisional SSIs. Moreover, the time at which patients typically present with an SSI has not been characterized. The primary aim of this study was to quantify the time from surgical intervention to the onset of superficial versus deep SSI. Methods: A retrospective review of 1933 foot and ankle procedures in 1632 patients from January 1, 2011 through August 31, 2015 was performed. Demographic data, type of surgery, subsequent diagnosis of superficial or deep incisional SSI, as well as amount and timing of antibiotic administration, incision, tourniquet and closure time were recorded. Superficial incisional SSIs were defined as those successfully treated with antibiotic therapy alone. Deep incisional SSIs were defined as those requiring subsequent wound irrigation and debridement (I&D). Time to treatment, outcomes and demographic variables were compared between patients that were treated with antibiotics alone and those that required I&D for definitive management. Results: 1569 procedures with complete data met inclusion criteria. There were 17 deep incisional SSIs (1.1%) that required I&D as part of definitive management. There were 63 superficial incisional SSIs (4.0%) that were treated successfully with antibiotics alone. The time interval between surgery and the initial treatment of deep incisional SSI (range: 11 to 42 days) was significantly greater than the time interval between surgery and initial treatment of superficial incisional SSI (range: 4 to 38 days) (28.18 ± 9.11 vs. 13.40 ± 4.65 days, p=<0.001). A total of 11 of 17 (64.7%) infections ultimately diagnosed as deep incisional SSIs failed a trial of antibiotics prior to I&D, in the remaining 6 of 17 (35.3%) infections antibiotics were held until intra-operative wound cultures were obtained. Conclusion: In our cohort of patients undergoing foot and ankle surgery the time to initial diagnosis and treatment of deep incisional SSI was longer than the time to diagnosis and treatment of superficial incisional SSI. Moreover, deep infections did not present until four weeks after surgery on average; this data is of some benefit in trying to define and understand SSIs.

Category: Bunion, Trauma, Other Introduction/Purpose: Immobilization is required for management of acute and chronic pathologic states of the hallux metatarsophalangeal (MTP) joint. Traditionally, this was performed using physician applied custom splint or cast and achieved a high degree of immobilization. Braces and orthotics are becoming less expensive and have several advantages, such as light weight and convenience in removal. However, this may come at the expense of ability to restrict movement. We hypothesize that generic braces will provide as much immobilization as custom applied plaster splints. Methods: Healthy volunteers were instrumented with electromagnetic sensors over bony prominences of the right foot. Range of motion exercises and activities of daily living were performed without an immobilization device. The same procedure was repeated with each of three immobilization devices: a post-operative shoe, a walking boot, and a custom applied plaster splint. Position and angular data were collected to determine range of motion primarily of the hallux MTP joint. This study was approved by the hospital IRB Results: Compared to baseline, all three immobilization devices significantly reduced range of motion at the MTP joint in non- weight bearing with the ankle in dorsiflexion and plantarflexion (p<0.05). There was no significant difference detected between the devices. There was no significant difference in hallux motion during the standing exercise in any of the immobilization devices compared to baseline. During stance phase of gait, all three devices reduced range of motion at the MTP joint compared to baseline (p<0.05), though there was no statistically significant difference between devices. Conclusion: Consistent with the hypothesis, data from this study show that all both generic devices and the physician applied splint reduced range of motion compared to baseline. Unfortunately, the study was not powered enough to detect significant differences between the devices, though there was a trend towards the walking boot providing more immobilization.

Published: September 2017

Category: Ankle, Ankle Arthritis Introduction/Purpose: In the last two decades, total ankle replacement (TAR) has gained more acceptance as a treatment option in patients with end-stage ankle osteoarthritis. However, there is a lack of literature on TAR using a lateral transfibular approach. Therefore, we sought to report early clinical and radiographic results of a patient cohort treated with TAR using a lateral transfibular approach by a single surgeon. Methods: Fifty-five primary total ankle arthroplasties using the Zimmer trabecular metal implant were performed in 54 patients (29 men and 25 women; mean age, 67.0 years) from October 2012 to December 2014. Clinical assessment including pain evaluation and measurement of ankle range of motion was done preoperatively and at the latest follow-up. Weight-bearing radiographs were used to determine the angular alignment of the tibial and talar components and to analyze the bone-implant interface. Intraoperative and postoperative complications, revision surgeries, and failures were evaluated. Results: Implant survival was 93% at 36 months follow-up. There were 3 revisions of a tibial component due to aseptic loosening. In 10 of 55 procedures, a secondary procedure was performed during follow-up. Mean follow-up duration was 26.6 ± 4.2 months. No delayed union or non-union was observed for fibula healing. The average VAS pain score decreased significantly from 7.9 ± 1.3 to 0.8 ± 1.2. The average total range of motion increased significantly from 22.9° ± 11.8° to 40.2° ± 11.8°. Conclusion: Early results of Zimmer trabecular metal total ankle replacement demonstrated improved patient-reported outcomes and increased ankle motion at a minimum follow-up of one year. In the first 55 consecutive cases, the fibular osteotomy required for access to the ankle healed without complications. Painful early loosening requiring revision due to lack of bony ingrowth was seen in 3 of 55 cases.

Category: Ankle, Sports, Trauma Introduction/Purpose: Achilles tendon repairs have traditionally been performed using a prone position. Prone positioning gives the surgeon easy visualization of the tendon, but may not offer the safest position for anesthesia and requires more peri-operative positioning time. We propose that the use of a supine position for primary Achilles tendon repairs offers similar surgical times, while saving non-surgical operating room time during positioning and anesthesia set-up. Methods: A retrospective review of primary Achilles tendon repairs done at our institution’s surgical sites between March of 2010 and July of 2015 was performed. Using the institutional database, 145 procedures were identified. Chart review demonstrated that 82 were performed open-supine (OS), 31 were performed open-prone(OP), and 32 were performed percutaneous-prone(PP). Surgical, non-surgical, and total operating room times were compared between the three groups. Results: Average surgical times were 32.8, 49, and 32.3 minutes for the OS, OP, and PP procedures, respectively. Total operating rooms times were 59.1, 88.9, and 76.7; while non-surgical times spent in the operating rooms were 26.3, 39.9, and 44.4 minutes for these groups, respectively. Achilles tendons repaired either OP or PP resulted in an additional 13.6 and 18.1 (average 15.9) minutes of operating room time. There was not an increase in complications with the supine procedure compared to the prone procedures. Conclusion: Primary Achilles tendon repairs can be performed effectively using an open technique in a supine position, saving non-surgical operating room time without increasing complications. The supine position may also offer a safer method of providing anesthesia to these patients by allowing the anesthesiologist a more accessible airway and decreasing the risks involved with placing an intubated patient into a prone position.
Bridge Plate Fixation Results in Better Functional Outcomes Than Transarticular Screw Fixation for Low-Energy Lisfranc Injuries
Authors: Bellamy Joseph , Cochran Grant 
Published: September 2017

Category: Midfoot/Forefoot, Sports, Trauma Introduction/Purpose: Open reduction and internal fixation (ORIF) with transarticular screws or bridge plating is the standard of care for unstable Lisfranc injuries. There are no studies comparing the clinical outcomes of fixation with transarticular screws or bridge plates in young, athletic patients who sustained low-energy injuries. Methods: All low-energy Lisfranc injuries that underwent ORIF between 2010 and 2015 were reviewed. Injuries were classified as low-energy if the occurred during athletic activity, ground level twisting, or a fall from less than three feet (typically stairs or curbs). Tarsometatarsal (TMT) joint fixation with transarticular screws or bridge plating was documented. Transarticular screws were typically removed between four and six months postoperatively. Injury characteristics, complication rates, pain scores, and Foot and Ankle Ability Measure (FAAM) scores were compared. All continuous variables were compared with a two-tailed Student t-test. All categorical variables were compared using the Chi Squared test. Results: Of the fifteen patients identified, nine were fixed with transarticular screws and six with bridge plates. Average patient age was 27 years old. 12 of 15 were primarily ligamentous injuries. Implant removal was performed in the entire transarticular screw group and three out of six in the bridge plate group (p=0.018). Secondary arthrodesis for arthritis was recommended in two of the transarticular screw group and none of the bridge plate group (p=0.21). Mean FAAM scores were significantly higher in all subscales (ADL 96.2 v 76.7 p=.035, ADL SANE 92.5 v 72.6 p=.055, Sport 89.5 v 62.5 p=.027, Sport SANE 90 v 58.7 p=.024) in the bridge plate group at an average of 43 months follow up. Conclusion: In this study, ORIF with bridge plate fixation of the TMT joints had a lower rate of HWR and higher medium term FAAM scores than fixation with transarticular screws. A statistically significant difference in rates of secondary arthritis could not be established in this small cohort. Prospective studies are necessary to confirm these findings.
Clinical Outcomes of Screw Fixation for Ligamentous Injuries to the Ankle Syndesmosis in Athletes
Authors: Chambers Monique , Kromka Joseph , Hogan MaCalus 
Published: September 2017

Category: Sports Introduction/Purpose: Injuries to the ankle syndesmosis are commonly seen in the general population as well as in athletes [1]. Literature is mixed on the effectiveness of the two fixation techniques – rigid screw and suspensory fixation [2]. Specifically, data is lacking in an athletic population. Hypothesis: We hypothesize that in patients treated with rigid screw fixation, athletes will have a higher incidence of hardware-associated pain, screw breakage, and screw removal compared to non-athletes. Methods: This study was a retrospective review of a patients from eight orthopedic surgeons within the UPMC system. All patients underwent surgical stabilization of the ankle syndesmosis with a rigid screw. Exclusion criteria included age <15 years or >45 years, polytrauma, injury to the ankle articular surface, neurological impairment, chronic medical conditions, and other disabilities. Athlete status was assigned based on mention of participation in athletic activity at the high school level or higher in the electronic medical record. The incidence of hardware-associated pain, screw breakage, and screw removal in athletes vs. non- athletes were evaluated using chi-squared and fisher’s exact tests. tests. Results: Fifty-five patients met the eligibility criteria. Of these patients, 21 athletes were identified with 34 being non-athletes. In terms of patient characteristics, the athlete group was 90% male, 48% right sided injury, and with an average age of 26.6 (SD 6.8). The non-athlete group was 59% male, 47% right sided injury, and with an average age of 33.6 (SD 6.6). Athletes were observed to have higher incidence of hardware-associated pain (6 (29%) vs. 6 (18%), p=0.341), screw breakage (8 (38%) vs. 8 (24%), p=0.248), and screw removal (19 (90%) vs. 23 (68%), p=0.100) compared to non-athletes in this study. However, only the comparison for screw removal approached statistical significance. Conclusion: The results suggest that even in an age matched population, athletes may have higher incidence of screw removal. This study did not have sufficient power to demonstrate a statistical difference in hardware-associated pain or screw breakage, although these did occur at a higher rate in the athlete population. A larger study will be needed to demonstrate statistical significance. Nevertheless, these results suggest that it may make sense to use the suspensory fixation method in athletes in order to avoid a second surgery for hardware removal.

Authors: Choi Seung-Myung , Cho Byung-Ki 
Published: September 2017

Category: Ankle, Diabetes, Trauma Introduction/Purpose: Factors predicting complications after surgical treatment of geriatric ankle fractures include presence of various comorbidities such as diabetes, chronic renal disease. However, beyond the binary definition of presence or absence, further speci? c information of these comorbidities such as their chronicity, severity and/or perioperative laboratories have not been studied as risk factors for postoperative complications. The purpose of this study is to investigate the association between the measurements of comorbidities and complications within the? rst 30 days following surgical treatment of geriatric ankle fracture. Methods: A retrospective cohort study. From 2000 to 2015, we collected patient demographics, comorbidities-related data including laboratory values and complications within 30 days following open reduction and internal fixation of low energy ankle fractures in patients older than 65 years. Multiple logistic regression analysis was performed to determine factors affecting minor (super? cial wound infection, delayed wound healing, urinary tract infection, pneumonia), major complications (deep wound infection, loss of? xation, deep venous thrombosis, organ/space failure). Results: In total, 1,358 patients were included for analysis. The average age was 70.54 years (SD, 7.40). There were 895 (66%) females and 463 (34%) males. Baseline glucose concentrations >200 mg/dL (p < 0.001) and the mean 48 hour postoperative serum glucose concentrations >150 mg/dL (p < 0.001), history of taking wound compromising medications (p = 0.003) were signi? cantly associated with minor complications. Preoperative glycated hemoglobin (HbA1c) >6.5% (p < 0.001), estimated glomerular? ltration rate (eGFR) <45 mL/min/1.73 m2 (p < 0.001), dependent functional status and presence of two or comorbidities (p < 0.001) were statistically associated with major complications. Conclusion: poor glycemic control in the perioperative period, wound-compromising medications were associated with increased rates of minor complications, whereas poor chronic glycemic control (HbA1c), decreased renal function and vulnerability with multiple comorbid conditions were associated with major complications. Perioperative blood glucose management may prevent minor complications, whereas and mean serum glucose concentrations of 150 mg/dL and higher during this time period

Published: September 2017

Category: Hindfoot Introduction/Purpose: Adult acquired flatfoot deformity (AAFD) represents a biomechanical derangement involving the three- dimensional (3D) midfoot and hindfoot osseous complex, and can be challenging to optimally characterize using conventional two- dimensional (2D) plain radiographs. Weightbearing (WB) ConeBeam CT (CBCT) can better demonstrate the deformity of the 3D structures during WB. Therefore, we compared validated AAFD measurements between WB conventional radiographs and WB CBCT images. Methods: In this prospective, IRB approved and HIPAA compliant study, 20 patients (20 feet, 15 right and 5 left) with clinical diagnosis of flexible AAFD were included, 12 males and 8 females, with a mean age of 52.2 years (range, 20 to 88 years of age), and average BMI of 30.35 kg/m2 (range, 19.00 to 46.09 kg/m2). Involved feet underwent standing (WB) anteroposterior (AP) and lateral radiographs, and were also scanned by WB CBCTs. Both imaging modalities were assessed with traditional AAFD measurements obtained at sagittal (lateral view on radiograph) and axial (anteroposterior view on radiograph) planes using predefined anatomical landmarks, by two independent and blinded foot and ankle fellowship-trained observers. Intra- and Inter- observer reliabilities for both imaging modalities were calculated using Pearson correlation. WB radiograph and WB CBCT measurements were compared by T-Test of the means. P- values < 0.05 were considered significant. Results: There was good to excellent intra and inter-observer agreements for most of the measurements on both radiographs and WB CBCT images, with slightly better results favoring WBCT measurements. When comparing WB radiographs and WB CBCT images, we found significant differences in the mean values for some of the measurements, including: talus-first metatarsal angle in the sagittal plane (11.34° x 21.73°, p<0.0001), navicular-medial cuneiform angle (13.19° x 7.63°, p<0.0004), medial cuneiform to floor distance (6.70 mm x 5.50 mm, p<0.0003) and navicular to floor distance (31.34 mm x 23.22 mm, p<0.0001). No significant differences were found when measuring: talus-first metatarsal angle in the axial plane, talar uncoverage angle, cuboid to floor distance and calcaneal inclination angle. Conclusion: Traditional adult acquired flatfoot deformity radiographic measurements are obtainable using high resolution 3D WB CBCT imaging. Measurements performed on WB CBCT have similar intra-observer and overall higher inter-observer reliability when compared to WB radiographs. The statistically significant differences found in some of the measurements, when comparing both imaging techniques, might be related to a better characterization of the three-dimensional deformity on WB CBCT images.
