RESUMO
While the Lapidus bunionectomy is a common procedure utilized to address hallux valgus, the incidence of secondary surgery is not well established. Our primary goal was to determine the incidence of revision surgery and hardware removal following the Lapidus bunionectomy in addition to the risk factors associated with each. A retrospective nested case-control study of adult patients who underwent a Lapidus bunionectomy for symptomatic hallux valgus over a 9-year period was performed. The incidence rates and 95% confidence intervals (CI) of secondary surgery in the 3 years following the procedure along with the estimated independent associations and odds ratios between baseline demographic, clinical, and radiographic characteristics were calculated. Of the original cohort of 2540 patients, 127 were identified (5.0%; CI: 4.1%, 5.8%) who underwent revision surgery and 165 (6.5%; CI: 5.5%, 7.5%) who underwent hardware removal following Lapidus bunionectomy. Initially, the hallux valgus angle, intermetatarsal angle, and tibial sesamoid position were risk factors for revision surgery. However, in adjusted analyses for revision surgery, using a screw for third point of fixation emerged as the only independent risk factor (odds ratio [OR] = 3.01; CI: 1.59, 5.69). In adjusted analyses for hardware removal, female sex (OR = 2.33; CI: 1.08, 5.00) and third point of fixation (OR = 2.92; CI: 1.82, 4.69) emerged as independent risk factors. While the overall risks associated with Lapidus bunionectomy are low and the need for revision surgery are low, this study helps to identify specific risk factors for secondary surgery and hardware removal to help in evaluation and discussion with patients.
RESUMO
Our group previously reported that melanoma of the foot is associated with advanced disease on diagnosis and decreased survival. Lesions localized to the toe appeared to have the worst outcomes. In this study, we both expanded our study to include a 10-year population of patient with invasive melanoma of the foot and ankle and investigated additional factors associated with prognosis. Between January 2007 and December 2016, 211 patients underwent biopsy diagnosis and surgery for invasive melanoma in the BLANK health care system. Demographic, pathologic, staging, and localization characteristics were studied for overall survival. Lesions were localized to dorsal foot, plantar foot, toe (nonsubungual), and toe (subungual) locations. Multivariable analysis found Breslow depth, ulceration, lymph node involvement, and subungual toe location to be associated with poorer survival. Overall survival rate for foot melanoma was 70.6%. Overall survival for nonsubungual toe melanoma was 60.7%, compared to 53.1% for subungual toe melanoma. Of the subungual melanomas, 37.5% of presented as deep lesions with a Breslow depth >4.0 mm. Subungual melanoma was statistically significant for and found to be an independent prognostic factor associated with poorer survival and advanced disease. Based on the results of this study, there should be a low threshold to biopsy suspicious lesions of the toe and foot with particular attention to be dedicated to subungual lesions.

The Lapidus arthrodesis is a powerful procedure for the correction of hallux valgus with metatarsus primus varus. Yet, first ray instability may persist despite correction of the primary deformity with 2 crossed screw fixation. A third screw is often utilized as the additional point of fixation for noteworthy residual transverse plane motion, but it is not without potential complications. The suture and button fixation device may be an appropriate alternative to the third screw construct. This retrospective cohort study identified clinical / radiographic outcomes and complication rates following a third point of fixation with either a screw or suture and button fixation device in patients undergoing a modified Lapidus arthrodesis. One surgeon performed all of the Lapidus procedure with a third screw while the other surgeon performed all with a suture and button fixation device. Of 136 consecutive patients who underwent a modified Lapidus arthrodesis, 83 (61%) patients required a third point of fixation for satisfactory stabilization of the first ray. Surgical technique was similar between the 2 surgeons; however, one utilized the suture and button fixation device method (n = 36), while the other used a third screw for fixation (n = 47). Many of the clinical outcomes, radiographic results, and the union rate were similar between the 2 methods. Nineteen (40%) complications occurred in the third screw group compared to 6 (17%) in the suture and button fixation device group. However, the third screw group demonstrated 100% maintenance of deformity correction at 1 year versus 95% in the suture and button fixation device group. Although fixation with a suture and button fixation device was associated with fewer complications, a larger study is necessary to determine if these variations are statistically significant.

Treatment of painful or malaligned ankle arthrodesis can present as a challenging issue. Several published studies have demonstrated that takedown of a painful ankle arthrodesis to total ankle arthroplasty can assist in restoring some sagittal plane motion and improving functional scores. The goal of this study was to contribute to the limited body of literature with the largest cohort and longest follow-up to date. A retrospective analysis was performed on patient and surgical characteristics of those who underwent a conversion of a painful ankle arthrodesis to a total ankle arthroplasty by 1 of 3 experienced total ankle arthroplasty surgeons from February 2003 to December 2016 with ≥2 years of follow up. Seventy-seven subjects were included for evaluation, with an implant retention rate of 88% (68 of 77) and mean follow-up of 8.3 years (range 2.6 to 15.8). Of the 11 (14%) failures (defined as retrieval or exchange of metallic components), 8 (10%) were revised to a total ankle replacement, 2 (2%) underwent revision arthrodesis, and 1 (1%) elected for below-the-knee amputation. The mean time since the primary arthrodesis was 8.6 years (range 1 to 44), and the longer time interval between primary arthrodesis to takedown total ankle arthroplasty did not correlate with poorer outcome scores or increased risk of failure. The mean American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot, Buechel-Pappas, and visual analog pain scale scores improved from preoperative values, with less satisfaction noted in those who needed revision surgery. The conversion of a painful ankle arthrodesis to a total ankle implant is a viable option to obtain range of motion and improved patient satisfaction scores similar to primary total ankle replacement.

Traditional postoperative care after open reduction internal fixation (ORIF) of unstable ankle fractures with syndesmotic instability includes non-weightbearing for 6 to 8 weeks. However, prolonged non-weightbearing may be detrimental. The goal of this case series was to assess the outcomes of early protected weightbearing after operative treatment of acute ankle fractures with syndesmotic instability requiring screw stabilization. Fifty-eight consecutive patients, treated from January 2006 to January 2013, met the inclusion criteria with a minimum follow up of 1 year. Electronic medical records and radiographs were reviewed for patient and surgical characteristics, postoperative complications, and maintenance of reduction. Patients initiated walking at an average of 10 days (range 1 to 15) postoperatively. Surgical treatment consisted of operative reduction with standard fixation devices and 1 or 2 trans-syndesmotic screws that purchased 4 cortices. All 58 patients maintained correction after surgery when allowed to weightbear early in the postoperative recovery. Five complications (8.6%) occurred in the 58 patients, which included 3 superficial infections (5.2%) and 2 cases (3.4%) of neuritis. The maintenance of reduction and low complication rate in this study support the option of early protected weightbearing after ankle fracture ORIF with trans-syndesmotic fixation.

Osteomyelitis of the foot and ankle is a challenge to treat and creates a significant demand on both the patient and the healthcare system. The purposes of this study were to determine the microorganisms associated with foot and ankle osteomyelitis, to evaluate the change in methicillin-resistant Staphylococcus aureus (MRSA) between 2005 and 2010, and to determine the relationship between these infecting organisms and patient comorbidities. The medical records for 302 patients diagnosed with osteomyelitis of the foot and ankle, 151 in 2005 and 151 in 2010, were randomly selected and evaluated. The authors reviewed the demographics, comorbidities, microorganism(s) confirmed with bone biopsy and culture, location, and use of antibiotics before bone biopsy. Gram-positive bacteria were the most prevalent, composing 81.9% of the isolates in 2005 and 59.6% in 2010. Methicillin-sensitive Staphylococcus aureus was the most common in both cohorts. Conversely, the incidence of MRSA statistically decreased from 28.3% to 10.6% from 2005 to 2010 (p < .0001). Gram-negative bacteria were found in 39.5% of the 2005 isolates and 31.8% of those from 2010. Pseudomonas sp. was the most common gram-negative bacteria. Patients with peripheral vascular disease had a significantly higher incidence of gram-negative bacteria (odds ratio 2.1, 95% confidence interval, 1.3 to 3.6, pâ¯=â¯.003). The results of this study reveal that MSSA was the most common bacteria, incidence of MRSA decreased between the 2005 to 2010, and patients with peripheral vascular disease have a significantly higher incidence of gram-negative bacteria.

Bisphosphonates (BP) are used to treat osteoporosis, although rare atypical femur fractures have occurred with long-term exposure, especially among Asians. Metatarsal fractures have also been reported with atypical femur fracture. We examined the epidemiology of metatarsal fractures among 48,390 females aged ≥50 years who initiated oral BP and were followed for a median 7.7 years, including 68 females who experienced an atypical femur fracture. Incident metatarsal fractures after BP initiation were identified by clinical diagnoses and validated by record review. The association of BP, clinical risk factors, race/ethnicity, and metatarsal fracture was examined by using Cox proportional hazard analyses. Among 1123 females with incident metatarsal fracture, 61.0% had an isolated fifth metatarsal fracture. The incidence of metatarsal fracture was 312 per 100,000 person-years of follow-up and was substantially lower for Asians. The adjusted relative rate for metatarsal fractures was 0.5 (95% confidence interval 0.4 to 0.6) for Asians compared with whites. Younger age, prior fracture, other risk factors, and current BP were associated with an increased relative rate of metatarsal fracture, but BP duration was not. Females with atypical femur fracture were not more likely to experience metatarsal fracture (2.9% versus 2.3%, pâ¯=â¯.7), but only 68 females had an atypical fracture and stress fracture of the metatarsals was not examined. Except for age, the demographic profile for metatarsal fracture after initiating BP was similar to that for osteoporotic fracture, with Asians at a much lower risk. Although metatarsal fractures were not associated with BP duration or atypical femur fracture, the subset of metatarsal stress fractures was not specifically examined.

There are multiple antirheumatic drug modalities available to patients with symptomatic rheumatoid arthritis (RA) that function to suppress the overactive immune system, but the inflammatory and immune suppression may contribute to postoperative complications. The purpose of this study was to determine if antirheumatic medications increased the risk of both soft tissue and osseous postoperative complications in patients with RA who underwent foot and ankle surgery. We reviewed patients with RA, aged 18years and older, who underwent either an elective or a nonelective foot or ankle surgery involving an osseous procedure between 2009 and 2014. Chart review was conducted to document procedure type, active medications, and postoperative complications. Of the final 110 subjects meeting inclusion criteria, 31 (28%) patients had a postoperative complication (13 soft tissue, 9 osseous, and 9 both soft tissue and osseous). There was no statistically significant association between taking antirheumatic medications in the perioperative period and postoperative complications. Increased surgery duration and peripheral neuropathy were associated with a statistically significant increase in postoperative complications. Every 15 minutes of increased surgery time led to a 1.2-fold increase in complication risk. Nonelective procedures had a higher risk of soft tissue complications than did elective procedures (odds ratio 4.2, 95% confidence interval 1.1 to 16.0). Although there was no statistically significant association between the specific medication and complications, some medications trended toward statistical significance. When working with patients with RA, our findings suggest the importance of considering the risk of surgery duration and the potential risk of antirheumatic medications in the perioperative period.

Modified Lapidus arthrodesis is a versatile and powerful procedure for correcting the hallux valgus deformity typically associated with significant metatarsus primus varus or increased first ray mobility. Traditionally, patients have remained non-weightbearing until the arthrodesis has consolidated. More recently, numerous studies have evaluated the outcomes of early postoperative weightbearing using a variety of fixation constructs. The present retrospective cohort study evaluated 136 consecutive patients who had undergone modified Lapidus arthrodesis for hallux valgus deformity with conventional, crossed, solid core, screw fixation, were enrolled in an early weightbearing protocol, and were followed for 12 months. All the patients were partial weightbearing in a protective boot a mean of 12.2 (SD ± 4.36) days after surgery, with full weightbearing at 34.4 (SD ± 11.89) days. Union was achieved in 133 patients (97.8%). Of the 3 (2.2%) patients with nonunion, 2 (1.5%) remained asymptomatic. The mean time to radiographic union was 65 (SD ± 37.24) days. Significant improvement was seen in the first intermetatarsal angle and hallux abductus angle after surgery (p < .0001). Deformity correction was not compromised by early weightbearing and was well maintained over time. These results support early weightbearing with traditional crossed screw fixation for modified Lapidus arthrodesis with outcomes and complication rates comparable to those previously published.

Hallux valgus with or without first ray insufficiency has been strongly implicated as a contributing factor in lesser metatarsal overload. The principle goals of a bunionectomy are to relieve the pain, correct the deformity, and restore first metatarsophalangeal joint congruity. Until now, little evidence has been available to assess the effects of bunionectomy procedures on forefoot pressure. The primary aim of the present prospective study was to evaluate the preoperative and postoperative plantar pressures after 2 specific bunionectomies: the chevron bunionectomy and Lapidus arthrodesis. A total of 68 subjects, 34 in each group, were included for radiographic and pedographic evaluation. Both procedures demonstrated radiographic improvements in the mean intermetatarsal and hallux abductus angles. The mean hallux plantar pressure decreased significantly in both procedure groups (p < .001). However, Lapidus group exhibited an increase in the mean fifth metatarsal head plantar pressure (p = .008) and pressure under the fifth metatarsal as a percentage of the total forefoot pressure (p = .01). Furthermore, the pressure under the second metatarsal as a percentage of the total forefoot pressure decreased significantly (p = .01). This study suggests that the Lapidus arthrodesis and chevron bunionectomy both provide correction for hallux valgus deformity, but when comparing forefoot load sharing pressures, the Lapidus arthrodesis appeared to have greater influence on the load sharing distribution of forefoot pressure than did the bunionectomy employing the chevron osteotomy.

A retrospective analysis of 107 Salto Talaris(®) total ankle replacements was performed to determine the effect of alignment and tibial cortical coverage on the formation of heterotopic bone. The radiographic parameters were studied for at least 18 months to detect any changes over time. The angle of insertion of the implant was most often in varus and with a positive anterior slope. A slight increase was seen in the slope over time (p < .0001) but was not clinically relevant. The mean percentage of cortical coverage of the tibial component was 89%, and only 7 patients had complete coverage of both the anterior and the posterior cortices. The percentage of patients who had hypertrophic bone growth increased over time (p < .0001). As the slope of the implant increased, there was a negative correlation with the degree of tibial coverage (p = .007). There was also an increase in the extent of hypertrophic bone as the tibial coverage decreased. None of the patients had symptoms that required an additional surgical procedure. The results of the present study indicate a high incidence of hypertrophic bone proliferation when the dimensions of the tibial component do not match the anteroposterior depth of the tibia at the plane of resection. Despite the high occurrence rate, the clinical relevance of hypertrophic bone is obscure.

There are many factors to consider when treating an Achilles tendon rupture in the acute and chronic/neglected settings. For acute rupture, operative and nonoperative management contribute to a good prognosis with low associated risks. Patient or injury characteristics can assist in the shared decision-making about treatment. In chronic rupture, MRI may help to determine rupture location, gap distance, and tissue material available for repair. Various surgical approaches are used for chronic rupture repair. Treatment of the Achilles tendon rupture generates many interesting and complex discussions on the optimal management.

Several methods have been described for fixation of unstable medial malleolar fractures. Certain patient populations, including the elderly, those with osteoporosis and osteopenia, and patients with diabetes mellitus, are generally known to be susceptible to complications associated with ankle fracture healing. The goal of the present retrospective investigation was to review the outcomes of a series of patients who had undergone medial malleolar fracture repair using fully threaded bicortical interfragmental compression screw fixation. Patients were included in the present series if they had undergone bicortical fixation of an unstable ankle fracture with a medial malleolar fracture component, in addition to having at least 1 of the following comorbidities: age 55 years or older, osteoporosis or osteopenia, diabetes mellitus, peripheral arterial disease, end-stage renal disease, chronic kidney disease, previous kidney transplantation, peripheral neuropathy, or current tobacco use. A total of 23 ankle fractures in 22 consecutive patients met the inclusion criteria. The mean age of the patients was 69.52 (range 45 to 89) years; 17 were female (77.27%) and 5 were male (22.73%). Of the 23 medial malleolar fractures, 21 (91.3%) achieved complete, uncomplicated healing. The mean interval to union was 62.6 (range 42 to 156) days. A total of 4 complications (17.39%) were noted, including 1 nonunion (4.35%), 1 malunion (4.35%), and 2 cases of painful retained hardware (8.7%). From our experience with this series of patients, bicortical screw fixation for medial malleolus fractures appears to be an acceptable alternative for fixation that provides a stable construct for patients at greater risk of bone healing complications.

Obesity is an epidemic in the United States and is associated with an increased risk of musculoskeletal problems. Rotational injuries of the ankle with a Weber C fibula fracture have a greater risk of syndesmosis disruption and instability. The goal of the present study was to explore the association between obesity and ankle fractures. Using a retrospective review, the radiographs of 280 patients with an ankle fracture were reviewed and classified using the Weber classification, which was then associated with the body mass index, gender, age, diabetes, tobacco use, and osteoporosis. Patients with a body mass index of 30 kg/m(2) or greater (odds ratio 1.78), men (odds ratio 1.74), and age 25 years or younger (odds ratio 3.97) had greater odds of having a Weber C ankle fracture (compared with Weber A and B) and Weber C and B (compared with Weber A). Diabetes mellitus, osteoporosis/osteopenia, and current tobacco use were not significantly associated with the severity of the ankle fracture. The results from the present study suggest that obesity presents a greater risk of sustaining a more proximal distal fibula fracture.

BACKGROUND: Verrucae are caused by infection of epidermal keratinocytes by human papilloma virus (HPV). Although there are currently more than 100 known types of HPV, certain lesions are consistently caused by infection with one or a few types. Recent studies have identified the presence of unusual HPV types in anogenital and cervical condylomata (warts) of patients infected with human immunodeficiency virus (HIV). Although cutaneous verrucae are typically caused by HPV-1, HPV-2, and HPV-4, infection with HIV may predispose an individual to infection with an unusual HPV type. METHODS: We report the detection of a rare HPV type in a clinically aggressive plantar verruca from an HIV-positive patient. The viral DNA from this specimen was analyzed to identify the predominant HPV type. To complete this analysis, HPV DNA was extracted from the formalin-fixed specimen, followed by polymerase chain reaction with consensus HPV primers and digestion with a specific group of restriction endonucleases. The fragments were separated on an agarose gel, and the restriction fragment length polymorphism pattern was compared with known patterns for identification of the specific HPV type. RESULTS: Identification of HPV-69, an HPV type previously reported to be rare and associated with dysplastic lesions, was confirmed by HPV DNA dot-blot hybridization with specific DNA probes for each known HPV type. CONCLUSIONS: Plantar verrucae in HIV-positive patients may be associated with unusual HPV types and should be analyzed and treated aggressively given the potential for a more distinct clinical manifestation. Additional lesional analysis studies are needed.

BACKGROUND: Implementation of highly active antiretroviral therapy (HAART) significantly increased the life expectancy of those living with human immunodeficiency virus (HIV). Except for prevalence, scientific reports regarding clinical manifestations of plantar verrucae in the post-HAART era are lacking. The objective of this study was to compare clinical manifestations of plantar verrucae between HIV-infected and noninfected individuals and then to compare these findings with those observed before the implementation of HAART. METHODS: Nineteen patients with plantar verrucae (ten with HIV and nine without HIV) were examined to determine the size, number, and clinical type of verrucae present. The two groups were first compared with each other and then with previously collected data from a similar analysis conducted in 1995, before the implementation of HAART. Statistical significance was determined using the Fisher exact test or the Wilcoxon rank sum test. RESULTS: No significant differences were observed in the size, number, or clinical type of verrucae between HIV-negative and HIV-positive patients. Compared with the 1995 data, there was a significant decrease in the number of verrucae lesions per individual and a nonsignificant decrease in the average size of verrucae in HIV-positive patients. CONCLUSIONS: Study results indicate that the implementation of HAART has impacted the clinical manifestations of plantar verrucae in HIV-positive individuals. Further analyses with a larger number of patients are required to confirm and substantiate these findings.

BACKGROUND: Although an increased prevalence of plantar verrucae has been associated with human immunodeficiency virus (HIV) infection, human papillomavirus (HPV) typing studies have not been published about this patient population. We sought to determine the prevalence of HPV types in plantar verrucae of HIV-positive (HIV+) and HIV-negative (HIV-) individuals. METHODS: Thirty-nine plantar verruca lesions in 17 individuals were examined. Nine participants were HIV+ and eight were HIV-. Detection of HPV was performed by polymerase chain reaction using two sets of primers: MY09/MY11. The type of HPV was determined by hybridization to 38 different HPV types. Clinical types of verrucae were correlated to the HPV strain identified in each lesion. RESULTS: Of the 39 plantar verruca samples, 38 typed to HPV-2, HPV-27, and HPV-57 strains in HIV+ and HIV- individuals. Specifically, a large proportion of the samples from HIV- individuals typed as HPV-27 (87.5%), and HPV-2 was the predominant type identified in HIV+ individuals (50%). No rare or atypical HPV types were found in either group. We identified HPV-2 and HPV-27 in 96% of verruca plantaris clinical type. Mosaic warts typed to HPV-27 and HPV-57, and 80% of punctate verrucae typed to HPV-57. CONCLUSIONS: This study presents an increased prevalence of HPV-2, HPV-27, and HPV-57 in plantar verrucae in this study population and provides insight into the occurrence of these types in HIV+ and HIV- individuals.

BACKGROUND: since the implementation of highly active antiretroviral therapy (HAART), the life expectancy of patients with human immunodeficiency virus (HIV) has significantly increased. This is likely to cause changes in podiatric medical manifestations, such as plantar verrucae, in this population. METHODS: attendees at a San Francisco street fair in 2008 provided information about HIV status and the presence of verrucae via a survey. A total of 504 surveys were analyzed and compared with 1995 data, before HAART implementation. We examined if there was a statistically significant change in the increased likelihood of plantar verrucae in HIV-positive patients from 1995 to 2008. Then we examined the likelihood of HIV-positive patients (compared to HIV-negative patients) presenting with plantar verrucae in 2008, by using logistic regression, and controlling for age, sex, and race/ethnicity. RESULTS: patients with HIV infection were 5.2 times more likely to present with plantar verrucae compared to patients without HIV infection in 2008 (95% confidence interval, 2.5-11.0, P < .0001) and 10.0 times more likely in 1995 (95% confidence interval, 3.4-29.0, P < .0001). This decrease in likelihood over time was not statistically significantly different (P = .33). Logistic regression analysis controlling for the covariates of age, race, and sex showed that patients with HIV in 2008 were 4.5 times more likely to present with verrucae compared to patients without HIV (95% confidence interval, 2.1-9.9, P = .0002). CONCLUSIONS: patients with HIV infection in 2008 are still significantly more likely to present with plantar verrucae after controlling for age, race, and sex. This increased likelihood has not changed significantly across time. Because HAART has increased the life expectancy of patients with HIV, this group of patients with plantar verrucae will continue to represent a significant population in the practice of podiatric medicine.
