Surgical reconstruction of deformed Charcot feet carries a high risk of nonunion, metalwork failure, and deformity recurrence. The primary aim of this study was to identify the factors contributing to these complications following hindfoot Charcot reconstructions. We retrospectively analyzed patients who underwent hindfoot Charcot reconstruction with an intramedullary nail between January 2007 and December 2019 in our unit. Patient demographic details, comorbidities, weightbearing status, and postoperative complications were noted. Metalwork breakage, nonunion, deformity recurrence, concurrent midfoot reconstruction, and the measurements related to intramedullary nail were also recorded.Aims
Methods
The ideal management of acute syndesmotic injuries in elite athletes is controversial. Among several treatment methods used to stabilize the syndesmosis and facilitate healing of the ligaments, the use of suture tape (InternalBrace) has previously been described. The purpose of this study was to analyze the functional outcome, including American Orthopaedic Foot & Ankle Society (AOFAS) scores, knee-to-wall measurements, and the time to return to play in days, of unstable syndesmotic injuries treated with the use of the InternalBrace in elite athletes. Data on a consecutive group of elite athletes who underwent isolated reconstruction of the anterior inferior tibiofibular ligament using the InternalBrace were collected prospectively. Our patient group consisted of 19 elite male athletes with a mean age of 24.5 years (17 to 52). Isolated injuries were seen in 12 patients while associated injuries were found in seven patients (fibular fracture, medial malleolus fracture, anterior talofibular ligament rupture, and posterior malleolus fracture). All patients had a minimum follow-up period of 17 months (mean 27 months (17 to 35)).Aims
Methods
In our unit, we adopt a two-stage surgical reconstruction approach using internal fixation for the management of infected Charcot foot deformity. We evaluate our experience with this functional limb salvage method. We conducted a retrospective analysis of prospectively collected data of all patients with infected Charcot foot deformity who underwent two-stage reconstruction with internal fixation between July 2011 and November 2019, with a minimum of 12 months’ follow-up.Aims
Methods
A pilon fracture is a severe ankle joint injury caused by high-energy trauma, typically affecting men of working age. Although relatively uncommon (5% to 7% of all tibial fractures), this injury causes among the worst functional and health outcomes of any skeletal injury, with a high risk of serious complications and long-term disability, and with devastating consequences on patients’ quality of life and financial prospects. Robust evidence to guide treatment is currently lacking. This study aims to evaluate the clinical and cost-effectiveness of two surgical interventions that are most commonly used to treat pilon fractures. A randomized controlled trial (RCT) of 334 adult patients diagnosed with a closed type C pilon fracture will be conducted. Internal locking plate fixation will be compared with external frame fixation. The primary outcome and endpoint will be the Disability Rating Index (a patient self-reported assessment of physical disability) at 12 months. This will also be measured at baseline, three, six, and 24 months after randomization. Secondary outcomes include the Olerud and Molander Ankle Score (OMAS), the five-level EuroQol five-dimenison score (EQ-5D-5L), complications (including bone healing), resource use, work impact, and patient treatment preference. The acceptability of the treatments and study design to patients and health care professionals will be explored through qualitative methods.Aims

Aims. Infected and deformed neuropathic feet and ankles are serious challenges for surgical management. In this study we present our experience in performing ankle arthrodesis in a closed manner, without surgical preparation of the joint surfaces by cartilaginous debridement, but instead using an Ilizarov ring fixator (IRF) for deformity correction and facilitating fusion, in arthritic neuropathic ankles with associated
The aim of this study was to describe the technique of distraction
osteogenesis followed by arthrodesis using internal fixation to
manage complex conditions of the ankle, and to present the results
of this technique. Between 2008 and 2014, distraction osteogenesis followed by arthrodesis
using internal fixation was performed in 12 patients with complex
conditions of the ankle due to trauma or infection. There were eight
men and four women: their mean age was 35 years (23 to 51) at the
time of surgery. Bone healing and functional recovery were evaluated
according to the criteria described by Paley. Function was assessed
using the ankle-hindfoot scale of the American Orthopedic Foot and
Ankle Society (AOFAS).Aims
Patients and Methods
The surgical challenge with severe hindfoot injuries is one of technical feasibility, and whether the limb can be salvaged. There is an additional question of whether these injuries should be managed with limb salvage, or whether patients would achieve a greater quality of life with a transtibial amputation. This study aims to measure functional outcomes in military patients sustaining hindfoot fractures, and identify injury features associated with poor function. Follow-up was attempted in all United Kingdom military casualties sustaining hindfoot fractures. All respondents underwent short-form (SF)-12 scoring; those retaining their limb also completed the American Academy of Orthopaedic Surgeons Foot and Ankle (AAOS F&A) outcomes questionnaire. A multivariate regression analysis identified injury features associated with poor functional recovery.Objectives

Aims. Hindfoot arthrodesis with retrograde intramedullary nailing has
been described as a surgical strategy to reconstruct deformities
of the ankle and hindfoot in patients with Charcot arthropathy.
This study presents case series of Charcot arthropathy patients
treated with two different retrograde intramedullary straight compression
nails in order to reconstruct the hindfoot and assess the results
over a mid-term follow-up. Patients and Methods. We performed a retrospective analysis of 18 consecutive patients
and 19 operated feet with Charcot arthropathy who underwent a hindfoot
arthrodesis using a retrograde intramedullary compression nail.
Patients were ten men and eight women with a mean age of 63.43 years
(38.5 to 79.8). We report the rate of limb salvage, complications requiring
additional surgery, and fusion rate in both groups. The mean duration
of follow-up was 46.36 months (37 to 70). Results. The limb salvage rate was 16 of 19 limbs. Three patients had
to undergo below-knee amputation due to persistent infection followed
by
Neuropathic changes in the foot are common with
a prevalence of approximately 1%. The diagnosis of neuropathic arthropathy
is often delayed in diabetic patients with harmful consequences
including amputation. The appropriate diagnosis and treatment can
avoid an extensive programme of treatment with significant morbidity
for the patient, high costs and delayed surgery. The pathogenesis
of a Charcot foot involves repetitive micro-trauma in a foot with impaired
sensation and neurovascular changes caused by pathological innervation
of the blood vessels. In most cases, changes are due to a combination
of both pathophysiological factors. The Charcot foot is triggered
by a combination of mechanical, vascular and biological factors
which can lead to late diagnosis and incorrect treatment and eventually
to destruction of the foot. This review aims to raise awareness of the diagnosis of the Charcot
foot (diabetic neuropathic osteoarthropathy and the differential
diagnosis, erysipelas, peripheral arterial occlusive disease) and
describe the ways in which the diagnosis may be made. The clinical
diagnostic pathways based on different classifications are presented. Cite this article:
We report the outcomes of 20 patients (12 men,
8 women, 21 feet) with Charcot neuro-arthropathy who underwent correction
of deformities of the ankle and hindfoot using retrograde intramedullary
nail arthrodesis. The mean age of the patients was 62.6 years (46
to 83); their mean BMI was 32.7 (15 to 47) and their median American
Society of Anaesthetists score was 3 (2 to 4). All presented with
severe deformities and 15 had chronic ulceration. All were treated
with reconstructive surgery and seven underwent simultaneous midfoot
fusion using a bolt, locking plate or a combination of both. At
a mean follow-up of 26 months (8 to 54), limb salvage was achieved
in all patients and 12 patients (80%) with ulceration achieved healing
and all but one patient regained independent mobilisation. There was
failure of fixation with a broken nail requiring revision surgery
in one patient. Migration of distal locking screws occurred only
when standard screws had been used but not with hydroxyapatite-coated
screws. The mean American Academy of Orthopaedic Surgeons Foot and
Ankle (AAOS-FAO) score improved from 50.7 (17 to 88) to 65.2 (22
to 88), (p = 0.015). The mean Short Form (SF)-36 Health Survey Physical
Component Score improved from 25.2 (16.4 to 42.8) to 29.8 (17.7
to 44.2), (p = 0.003) and the mean Euroqol EQ‑5D‑5L score improved
from 0.63 (0.51 to 0.78) to 0.67 (0.57 to 0.84), (p = 0.012). Single-stage correction of deformity using an intramedullary
hindfoot arthrodesis nail is a good form of treatment for patients
with severe Charcot hindfoot deformity, ulceration and instability
provided a multidisciplinary care plan is delivered. Cite this article:
Most of the literature on surgical site infections
following the surgical treatment of fractures of the ankle is based
on small series of patients, focusing on diabetics or the elderly.
None have described post-operative functional scores in those patients
who develop an infection. We performed an age- and gender-matched
case–control study to identify patient- and surgery-related risk
factors for surgical site infection following open reduction and
internal fixation of a fracture of the ankle. Logistic regression
analysis was used to identify significant risk factors for infection
and to calculate odds ratios (OR). Function was assessed using the
Olerud and Molander Ankle Score. The incidence of infection was
4% (29/717) and 1.1% (8/717) were deep infections. The median ankle
score was significantly lower in the infection group compared with
the control group (60 A low incidence of infection following open reduction and internal
fixation of fractures of the ankle was observed. Both superficial
and deep infections result in lower functional scores. Cite this article:

Achieving arthrodesis of the ankle can be difficult
in the presence of infection, deformity, poor soft tissues and bone loss.
We present a series of 48 patients with complex ankle pathology,
treated with the Ilizarov technique. Infection was present in 30
patients and 30 had significant deformity before surgery. Outcome
was assessed clinically and with patient-reported outcome measures
(Modified American Orthopaedic Foot and Ankle Society (MAOFAS) scale and
the Short-Form (SF-36)). Arthrodesis was achieved in 40 patients with the Ilizarov technique
alone and in six further patients with additional surgery. Infection
was eradicated in all patients at a mean follow-up of 46.6 months
(13 to 162). Successful arthrodesis was less likely in those with
comorbidities and in tibiocalcaneal fusion compared with tibiotalar
fusion. These patients had poor general health scores compared with the
normal population before surgery. The mean MAOFAS score improved
significantly from 24.3 (0 to 90) pre-operatively to 56.2 (30 to
90) post-operatively, but there was only a modest improvement in
general health; the mean SF-36 improved from 44.8 (19 to 66) to
50.1 (21 to 76). There was a major benefit in terms of pain relief. Arthrodesis using the Ilizarov technique is an effective treatment
for complex ankle pathology, with good clinical outcomes and eradication
of infection. However, even after successful arthrodesis general
health scores remain limited. Cite this article:
Open reduction and internal fixation of high-energy pilon fractures are often associated with serious complications. Various methods have been used to treat these injuries, with variable results. A total of 17 consecutive patients with pilon fractures of AO/OTA type 43-B3 (n = 1), type C2 (n = 12) and type C3 (n = 4) were treated by indirect reduction by capsuloligamentotaxis and stabilisation using an ankle-spanning Ilizarov fixator. The calcaneal ring was removed at a mean of 3.7 weeks (3 to 6). A total of 16 patients were available for follow-up at a mean of 29 months (23 to 43). The mean time to healing was 15.8 weeks (13 to 23). Nine patients had pin-track infections but none had deep infection or
Charcot osteoarthropathy of the foot is a chronic and progressive disease of bone and joint associated with a risk of amputation. The main problems encountered in this process are osteopenia, fragmentation of the bones of the foot and ankle, joint subluxation or even dislocation, ulceration of the skin and the development of deep sepsis. We report our experience of a series of 20 patients with Charcot osteoarthropathy of the foot and ankle treated with an Ilizarov external fixator. The mean age of the group was 30 years (21 to 50). Diabetes mellitus was the underlying cause in 18 patients. Five had chronic ulcers involving the foot and ankle. Each patient had an open lengthening of the tendo Achillis with excision of all necrotic and loose bone from the ankle, subtalar and midtarsal joints when needed. The resulting defect was packed with corticocancellous bone graft harvested from the iliac crest and an Ilizarov external fixator was applied. Arthrodesis was achieved after a mean of 18 weeks (15 to 20), with healing of the skin ulcers. Pin track infection was not uncommon, but no frame had to be removed before the arthrodesis was sound. Every patient was able to resume wearing regular shoes after a mean of 26.5 weeks (20 to 45).
Correction of valgus deformity of the hindfoot using a medial approach for a triple fusion has only recently been described for patients with tight lateral soft tissues which would be compromised using the traditional lateral approach. We present a series of eight patients with fixed valgus deformity of the hindfoot who had correction by hindfoot fusion using this approach. In addition, we further extended the indications to allow concomitant ankle fusion. The medial approach allowed us to excise medial ulcers caused by the prominent medial bony structures, giving simultaneous correction of the deformity and successful internal fixation. We had no problems with primary wound healing and experienced no subsequent infection or wound breakdown. From a mean fixed valgus deformity of 58.8° (45° to 66°) pre-operatively, we achieved a mean post-operative valgus angulation of 13.6° (7° to 23°). All the feet were subsequently accommodated in shoes. The mean time to arthrodesis was 5.25 months (3 to 9). We therefore recommend the medial approach for the correction of severe fixed valgus hindfoot deformities.
