Background: Substitutes for bone graft have been advocated to avoid the potential morbidity associated with harvest of autogenous iliac crest graft. However, no current commercially available graft equals autogenous bone's osteoinductive and osteoconductive qualities. We reviewed our patients' morbidity after harvest of anterior iliac crest bone grafts for procedures involving the foot and ankle. Methods: A computerized analysis of patient records was undertaken to identify all patients who had a harvest of unicortical iliac crest bone graft during a 12-year period. Patients were contacted either by telephone or by mailed questionnaire, inquiring about the postoperative morbidity of the procedure. Medical records were reviewed for any related complications. Results: Of the 169 patients identified, 134 could be contacted. Follow-up ranged from 1 to 13 years. Not all patients answered every question. At latest follow up, 120 (90%)-patients reported no pain at the bone graft site. Eleven patients complained of persistent residual numbness lateral to the harvest site on the pelvis. Of these 120 patients, 32 (27%) reported that pain at the graft site was greater than the pain at the operative site during the initial postoperative period. No patients had extra hospital days as a result of the bone graft harvest. No deep infections occurred, although 12 (6.7%) of 180 patients had a postoperative hematoma or seroma. Overall, 116 (90%) of 129 patients were satisfied or very satisfied with their bone graft harvest. Conclusions: Harvesting of autogenous iliac crest bone graft provides the optimal bone graft material, yields minimal morbidity, and is an acceptable choice in supplementing surgical procedures on the foot and ankle.

Objective: To review the techniques and results of surgical treatment of the superficial and perforating veins in patients with chronic venous insufficiency. Methods: The current techniques used at the Mayo Clinic for treatment of simple varicose veins and venous ulcers are presented. Results of subfascial endoscopic perforator vein surgery (SEPS) are discussed and data from large centres are tabulated. Results are compared with those reported following non-operative management. Synthesis: High ligation and invagination stripping of the incompetent segment of the saphenous vein, with stab avulsion of branch varicosities, is the optimal surgical technique to ablate superficial venous incompetence. SEPS is safer than open perforator vein ligation and is the technique of choice to interrupt incompetent perforating veins. A review of 12 series on SEPS, that included 361 limbs, found an ulcer recurrence rate of 10% in those 211 patients who underwent ablation of superficial reflux together with SEPS. One hundred and fifty limbs had SEPS alone, without saphenous stripping: ulcer recurrence in this group at a mean of 23 months was 12%. Results in primary valvular incompetence were significantly better than in post-thrombotic syndrome. Conclusions: Ablation of superficial reflux remains the main surgical treatment of all forms of chronic venous insufficiency. SEPS is safe and effective to interrupt medial calf perforators and results in rapid ulcer healing and low recurrence in patients with primary valvular incompetence. The treatment of post-thrombotic syndrome remains a challenge. Results of the North American Venous Ulcer Surgery (NAVUS) trial, a prospective, randomised, multicentre study, will be required to provide level 1 evidence of the effectiveness of surgical treatment over medical therapy in the treatment of venous ulcers.

AbstractPurposeThe increase in use of health information technologies (HIT) presents new opportunities for patient engagement and self‐management. Patients in rural areas stand to benefit especially from increased access to health care tools and electronic communication with providers. We assessed the adoption of 4 HIT tools over time by rural or urban residency.MethodsAnalyses were conducted using data from 7 iterations of the National Cancer Institute's Health Information National Trends Survey (HINTS; 2003‐2014). Rural/urban residency was based on the USDA's 2003 Rural‐Urban Continuum Codes. Outcomes of interest included managing personal health information online; whether providers maintain electronic health records (EHRs); e‐mailing health care providers; and purchasing medicine online. Bivariate analyses and logistic regression were used to assess relationships between geography and outcomes, controlling for sociodemographic characteristics.FindingsIn total, 6,043 (17.6%, weighted) of the 33,749 respondents across the 7 administrations of HINTS lived in rural areas. Rural participants were less likely to report regular access to Internet (OR = 0.70, 95% CI = 0.61‐0.80). Rural respondents were neither more nor less likely to report that their health care providers maintained EHRs than were urban respondents; however, they had decreased odds of managing personal health information online (OR = 0.59, 95% CI = 0.40‐0.78) and e‐mailing health care providers (OR = 0.62, 95% CI = 0.49‐0.77).ConclusionsThe digital divide between rural and urban residents extends to HIT. Additional investigation is needed to determine whether the decreased use of HIT may be due to lack of Internet connectivity or awareness of these tools.

The topic of wrist or carpal instability has been a source of confusion and miscommunication for decades. The terminology can often be difficult to understand and one surgeon's concept of instability may be completely different from another's. This is by no means a comprehensive review of carpal instability, which has often been the focus of numerous multi-volume textbooks. The purpose of this paper is to detail the basics of carpal instability, the anatomy, pathomechanics, terminology and basic principles of treatment.

Background: Screws have been recommended for fixation of the site of the metatarsal osteotomy. Methods: A report is presented on one surgeon's experience with a temporary, single Kirschner wire instead of screws for fixation of metatarsal neck osteotomies combined with proximal interphalangeal (PIP) joint resection arthroplasty in patients with dislocated metatarsophalangeal (MTP) joints and severe hammertoe deformities. Eleven consecutive patients (13 toes) were treated between January 1999 and January 2002 (mean age, 69 years; range, 44–81 years; seven women, four men) at a tertiary care foot and ankle center. Records and radiographs were reviewed retrospectively, and all patients were examined at follow-up by one of the authors (mean follow-up, 13 months; range, 6–32 months). Results: All 13 metatarsal neck osteotomies had clinical and radiographic union by 6 weeks, with no evidence of nonunion, malunion, avascular necrosis of the metatarsal head, deep wound infection, pin-tract infection, broken pins, or other serious complications. Two metatarsals (18%) had minor residual plantar calluses beneath the metatarsal head. The mean postoperative American Orthopaedic Foot and Ankle Society score was 76 of 95 points possible. All patients were satisfied with the procedure and would do it again. Conclusion: The use of a single, temporary K-wire provides adequate fixation for combined PIP joint resection arthroplasty and metatarsal neck osteotomy in patients with central metatarsalgia and severe hammertoe deformity.

SummaryTwo patients who shared similar presenting clinical features of anterograde and retrograde autobiographical amnesia typical of transient epileptic amnesia (TEA) underwent prolonged video electroencephalogram (VEEG) monitoring and were found to have sleep‐activated epileptiform activity and frequent subclinical bitemporal seizures predominantly during sleep. Case 1 is a 59‐year‐old woman whose presenting complaint was memory impairment. Over 18 months, she had three distinct 8‐h‐long episodes of confusion and disorientation with persistent anterograde and retrograde autobiographical amnesia. VEEG recorded frequent interictal bitemporal sharp waves confined to sleep, and 14 subclinical seizures, also mostly during sleep. Case 2 is a 50‐year‐old woman with known focal epilepsy also presented with memory complaints. Over the course of 1 year, she had two discrete 2‐h‐long episodes of amnesia, with ongoing anterograde and retrograde autobiographical amnesia. VEEG recorded independent bitemporal sharp waves, and 14 subclinical seizures during sleep and drowsiness. Memory impairment improved in both patients with successful treatment of their seizures. Although the etiology of accelerated long‐term forgetting (ALF) and remote memory impairment (RMI) in transient epileptic amnesia (TEA) is unknown, these cases suggest frequent sleep‐related seizures may contribute, and they highlight the importance of video‐EEG monitoring.

The proliferation of new endovascular devices and therapeutic strategies calls for a prudent and rational evaluation of their clinical benefit. This evaluation must be done in an effective manner and in collaboration with industry. Such research initiative requires organisational and methodological support to survive and thrive in a competitive environment. We propose the formation of an international consortium, an academic alliance committed to the pursuit of effective neurovascular therapies. Such a consortium would be dedicated to the design and execution of basic science, device development and clinical trials. The Consortium is owned and operated by its members. Members are international leaders in neurointerventional research and clinical practice. The Consortium brings competency, knowledge, and expertise to industry as well as to its membership across a spectrum of research initiatives such as: expedited review of clinical trials, protocol development, surveys and systematic reviews; laboratory expertise and support for research design and grant applications to public agencies. Once objectives and protocols are approved, the Consortium provides a stable network of centers capable of timely realization of clinical trials or preclinical investigations in an optimal environment. The Consortium is a non-profit organization. The potential revenue generated from client-sponsored financial agreements will be re-directed to the academic and research objectives of the organization. The Consortium wishes to work in concert with industry, to support emerging trends in neurovascular therapeutic development. The Consortium is a realistic endeavour optimally structured to promote excellence through scientific appraisal of our treatments, and to accelerate technical progress while maximizing patients' safety and welfare.

Background: Diabetic foot ulcers cause major treatment morbidity and cost of care. This study evaluated quality of life in patients with unhealed and healed diabetic foot ulcers. Methods: This was a cross-sectional study of adult diabetic patients (age 45 years or older) treated in a tertiary care foot clinic who had foot ulcers within the preceding 2 years. Patients with other diabetic complications or conditions that would potentially affect quality of life were excluded. Two patient groups of comparable age, gender distribution, and duration of diabetes were studied: 57 patients with unhealed ulcers (minimum duration, 6 months) and 47 patients with healed ulcers. Telephone interviews were done using the Short Form 12 (SF-12) (both groups) and a Cardiff Wound Impact Scale (CWIS) (unhealed ulcer group). Results: The mean SF-12 Physical Component Summary score was significantly lower for the group with unhealed ulcers (unhealed, 35 ± 8 points; healed, 39 ± 10 points; p = 0.04); these scores for both groups were significantly lower than published Short Form 36 (SF-36) scores for general, diabetic, and hypertensive populations. The mean SF-12 Mental Component Summary scores of the groups did not differ significantly from each other or from published population scores. CWIS responses showed that patients with unhealed ulcers were frustrated with healing and had anxiety about the wounds, resulting in marked negative impact on the average Well-being Component Score (35 ± 6 points). Conclusions: Individuals with diabetic foot ulcers experience profound compromise of physical quality of life, which is worse in those with unhealed ulcers.
