Abstract
INTRODUCTION Tibio-talo-calcaneal (TTC) fusion is a successful surgery for Charcot neuropathy affecting the hindfoot. A case series of Charcot neuropathy is presented with almost complete loss affecting hindfoot treated with tibio-talo-calcaneal nail. MATERIAL AND METHODS Seven patients with Charcot neuropathy of the hindfoot having varying degrees of talus loss underwent tibio-talo-calcaneal nailing between January 2014 and Feb 2016 at a tertiary care hospital by a single surgeon. All the patients were type 3a as per Brodsky classification. Patients with active infection, fractures and avascular necrosis of talus was excluded from the study. The final outcome was measured using the AOFAS and FADI scores at the end of 2 years. RESULTS The mean duration of diabetes was 8.16 ± 3.12 years. Two patients (28.6%) had total and 5 (71.4%) patients had subtotal talus loss. Anterior approach was used in four, and lateral approach was used in three cases respectively. The talus was reconstructed by using the iliac crest or the graft from the distal fibula wherever appropriate. The average surgical duration was 93.28 ± 4.84 min. One patient had deep infection, 2 years after the surgery which was treated by implant removal and antibiotics. No patients had non-union. The pre-operative AOFAS scores improved from 32.2 ± 2.58 to 73.4 ± 3.36 at 2-year follow-up (p < 0.0001). Similarly, the pre-operative FADI scores were 31.74 ± 1.98 which improved to 65.94 ± 3.68 at the end of 2 years (p < 0.0001). CONCLUSION Retrograde tibio-talo-calcaneal nail is a good option for limb salvage in patients with severe talus loss with good functional outcome. LEVEL OF EVIDENCE Therapeutic IV.

Abstract
BACKGROUND Charcot neuropathy is a common complication resulting from poorly controlled diabetes and peripheral neuropathy leading to the collapse, and ultimately the breakdown, of the midfoot. Mechanically, it is likely that a compromised arch support in this, or any other patient group that experiences foot flattening, would be associated with slippage at the distal and proximal interface regions of the plantar surface of the foot and the adjacent support surface. This slippage, although difficult to quantify with standard motion capture systems used in a gait laboratory, could potentially be assessed with systems for monitoring interface shear stresses. However, before investing in such systems, a correlation between arch flattening and interface shear stresses needs to be verified. METHODS For this purpose, a sagittal plane model of a foot was developed using a multi-body dynamics package (MSC Adams). This model mimicked a subject swaying back and forth, and was constructed to show the dependence of interface stresses on altered arch support. FINDINGS The model's predictions matched typical FootSTEPS data: lengthening of the arch of 1-2 mm, sway oscillations of 0.22-0.33 s and frictional force differences (calcaneus relative to forefoot) of 60 N. Of clinical relevance, when the stiffness of the plantar spring (representing aponeurosis and intrinsic muscles) was reduced by 10%, the frictional force difference increased by about 6.5%. INTERPRETATION The clinical implications of this study are that, while arch lengthening of less than 2 mm might be difficult to measure reliably in a gait lab, using shear sensors under the forefoot and hindfoot should allow arch support to be assessed in a repeatable manner.

Abstract
PURPOSE Ankle Charcot neuroarthropathy presents a great challenge for treatment. While conservative treatments yield poor results, arthrodesis is considered the treatment of choice for unstable Charcot ankles. There are two methods used for ankle fusion: retrograde intramedullary nail (IMN) and external fixator (EF). Literature reports inconclusive results on which method is better for arthrodesis. METHODS The aim of this meta-analysis is to look for significant difference between the two techniques in terms of fusion rate and complications. Four comparative studies including 117 patients (117 interventions) were located and analyzed. RESULTS IMN was found to yield double fusion rate than EF ( p = 0.2) with 5 weeks less time to heal ( p = 0.4). While no significance was noted for revision surgery and amputation rates, EF yielded higher rates of hardware infection ( p = 0.01) and wound infection ( p = 0.01). The IMN method seems to offer quicker and better fusion rate when compared to EF with significantly lower postoperative infection rates. CONCLUSION In the clinical context of high-risk patients such as the diabetic population, IMN technique could be a better option in the case of ulcer-free ankles/feet or in the presence of medial/lateral ulcers. In case of presence of plantar ulcers, EF might be a better choice to avoid the plantar approach for nail insertion. Future research with bigger sample sized and randomized studies are warranted for validation.

Abstract
OPINION STATEMENT Despite an explosion in the number of options available for helping diabetic patients heal wounds, major amputation remains a critical issue for these persons. Since diabetes prematurely ages tissues and no organ system is immune to its presence, it makes inherent sense that multi-disciplinary team approaches to these patients is necessary to make significant strides forward. Here, we present literature from the fields of podiatric surgery/medicine, vascular and plastic surgery and introduce the successes that a multi-disciplinary limb salvage center can have on the lives and limbs of patients with diabetes.

Abstract
This review describes the normal healing process for bone, ligaments, and tendons, including primary and secondary healing as well as bone-to-bone fusion. It depicts the important mediators and cell types involved in the inflammatory, reparative, and remodeling stages of each healing process. It also describes the main challenges for clinicians when trying to repair bone, ligaments, and tendons with a specific emphasis on Charcot neuropathy, fifth metatarsal fractures, arthrodesis, and tendon sheath and adhesions. Current treatment options and research areas are also reviewed.

Abstract
Charcot neuroarthropathy (CN) of the foot and ankle is a demanding clinical dilemma, and surgical management can be very complicated. Historically, the evidence guiding surgical management of CN has been small retrospective case series and expert opinions. The purpose of the present report was to provide a systematic review of studies published from 2009 to 2014 and to review the indications for surgery. A Medline search was performed, and a systematic review of studies discussing the surgical management of CN was undertaken. Thirty reports fit the inclusion criteria for our study, including 860 patients who had undergone a surgical procedure for the treatment of CN. The surgical procedures included amputation, arthrodesis, debridement of ulcers, drainage of infections, and exostectomy. The midfoot was addressed in 26.9% of cases, the hindfoot in 41.6%, and the ankle in 38.4%. Of the 30 studies, 24 were retrospective case series (level 4), 4 were controlled retrospective studies (level 3), and 2 were level II studies. The overall amputation rate was 8.9%. The quality of the published data on the surgical management of CN has improved during the past several years. Evidence concerning the timing of treatment and the use of different fixation methods remains inconclusive.
