Aims. 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. Methods. 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. Results. We identified 23 feet in 22 patients with a mean age of 56.7 years (33 to 70). The mean postoperative follow-up period was 44.7 months (14 to 99). Limb salvage was achieved in all patients. At one-year follow-up, all ulcers have healed and independent full weightbearing mobilization was achieved in all but one patient. Seven patients developed new mechanical skin breakdown; all went on to heal following further interventions. Fusion of the hindfoot was achieved in 15 of 18 feet (83.3%). Midfoot fusion was achieved in nine of 15 patients (60%) and six had stable and painless fibrous nonunion. Hardware failure occurred in five feet, all with broken dorsomedial locking plate. Six patients required further surgery, two underwent revision surgery for infected nonunion, two for removal of metalwork and exostectomy, and two for dynamization of the hindfoot nail. Conclusion. Two-stage reconstruction of the infected and deformed Charcot foot using internal fixation and following the principle of ‘long-segment, rigid and durable internal fixation, with optimal bone opposition and local
The Vantage Total Ankle System is a fourth-generation low-profile fixed-bearing implant that has been available since 2016. We aimed to describe our early experience with this implant. This is a single-centre retrospective review of patients who underwent primary total ankle arthroplasty (TAA) with a Vantage implant between November 2017 and February 2020, with a minimum of two years’ follow-up. Four surgeons contributed patients. The primary outcome was reoperation and revision rate of the Vantage implant at two years. Secondary outcomes included radiological alignment, peri-implant complications, and pre- and postoperative patient-reported outcomes.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 osteomyelitis. Methods. We retrospectively reviewed all the patients who underwent closed ankle arthrodesis (CAA) in Ilizarov Scientific Centre from 2013 to 2018 (Group A) and compared them with a similar group of patients (Group B) who underwent open ankle arthrodesis (OAA). We then divided the neuropathic patients into three arthritic subgroups: Charcot joint, Charcot-Maire-Tooth disease, and post-traumatic arthritis. All arthrodeses were performed by using an Ilizarov ring fixator. All patients were followed up clinically and radiologically for a minimum of 12 months to assess union and function. Results. The union rate for Group A was 81% (17/21) while it was 84.6% (33/39) for Group B. All the nonunions in Group A underwent revision with an open technique and achieved 100% union. Mean duration of IRF was 71.5 days (59 to 82) in Group A and 69 days (64.8 to 77.7) in Group B. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was similar in both groups. The postoperative hospital stay was shorter in Group A (21 days (SD 8)) than Group B (28 days (SD 9)). In the latter Group there were more problems with wound healing and greater requirement for
The aim of this study was to compare the longer-term outcomes of operatively and nonoperatively managed patients treated with a removable brace (fixed-angle removable orthosis) or a plaster cast immobilization for an acute ankle fracture. This is a secondary analysis of a multicentre randomized controlled trial comparing adults with an acute ankle fracture, initially managed either by operative or nonoperative care. Patients were randomly allocated to receive either a cast immobilization or a fixed-angle removable orthosis (removable brace). Data were collected on baseline characteristics, ankle function, quality of life, and complications. The Olerud-Molander Ankle Score (OMAS) was the primary outcome which was used to measure the participant’s ankle function. The primary endpoint was at 16 weeks, with longer-term follow-up at 24 weeks and two years.Aims

Although absorbable sutures for the repair of acute Achilles tendon rupture (ATR) have been attracting attention, the rationale for their use remains insufficient. This study prospectively compared the outcomes of absorbable and nonabsorbable sutures for the repair of acute ATR. A total of 40 patients were randomly assigned to either braided absorbable polyglactin suture or braided nonabsorbable polyethylene terephthalate suture groups. ATR was then repaired using the Krackow suture method. At three and six months after surgery, the isokinetic muscle strength of ankle plantar flexion was measured using a computer-based Cybex dynamometer. At six and 12 months after surgery, patient-reported outcomes were measured using the Achilles tendon Total Rupture Score (ATRS), visual analogue scale for pain (VAS pain), and EuroQoL five-dimension health questionnaire (EQ-5D).Aims
Methods
This study reports updates the previously published two-year clinical, functional, and radiological results of a group of patients who underwent transfibular total ankle arthroplasty (TAA), with follow-up extended to a minimum of five years. We prospectively evaluated 89 patients who underwent transfibular TAA for end-stage osteoarthritis. Patients’ clinical and radiological examinations were collected pre- and postoperatively at six months and then annually for up to five years of follow-up. Three patients were lost at the final follow-up with a total of 86 patients at the final follow-up.Aims

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 osteomyelitis resistant to parenteral
The aim of this study was to investigate whether on-demand removal (ODR) is noninferior to routine removal (RR) of syndesmotic screws regarding functional outcome. Adult patients (aged above 17 years) with traumatic syndesmotic injury, surgically treated within 14 days of trauma using one or two syndesmotic screws, were eligible (n = 490) for inclusion in this randomized controlled noninferiority trial. A total of 197 patients were randomized for either ODR (retaining the syndesmotic screw unless there were complaints warranting removal) or RR (screw removed at eight to 12 weeks after syndesmotic fixation), of whom 152 completed the study. The primary outcome was functional outcome at 12 months after screw placement, measured by the Olerud-Molander Ankle Score (OMAS).Aims
Methods
Limited forefoot amputation in diabetic patients
with osteomyelitis is frequently required. We retrospectively reviewed
diabetic patients with osteomyelitis, an unhealed ulcer and blood
pressure in the toe of >
45 mmHg who underwent limited amputation
of the foot with primary wound closure. Between 2006 and 2012, 74
consecutive patients with a mean age of 67 years (29 to 93), and
a median follow-up of 31 months, were included. All the wounds healed
primarily at a median of 37 days (13 to 210; mean 48). At a median
of 6 months (1.5 to 18; mean 353 days), 23 patients (31%) suffered
a further ulceration. Of these, 12 patients (16% of the total) required
a further amputation. We conclude that primary wound closure following limited amputation
of the foot in patients with diabetes is a safe and effective technique
when associated with appropriate
We report the medium-term outcomes of a consecutive series of 118 Zenith total ankle arthroplasties (TAAs) from a single, non-designer centre. Between December 2010 and May 2016, 118 consecutive Zenith prostheses were implanted in 114 patients. Demographic, clinical, and patient-reported outcome measures (PROMs) data were collected. The endpoint of the study was failure of the implant requiring revision of one or all of the components. Kaplan-Meier survival curves were generated with 95% confidence intervals (CIs) and the rate of failure calculated for each year.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
Methods
Preoperative talar valgus deformity ≥ 15° is considered a contraindication for total ankle arthroplasty (TAA). We compared operative procedures and clinical outcomes of TAA in patients with talar valgus deformity ≥ 15° and < 15°. A matched cohort of patients similar for demographics and components used but differing in preoperative coronal-plane tibiotalar valgus deformity ≥ 15° (valgus, n = 50; 52% male, mean age 65.8 years (SD 10.3), mean body mass index (BMI) 29.4 (SD 5.2)) or < 15° (control, n = 50; 58% male, mean age 65.6 years (SD 9.8), mean BMI 28.7 (SD 4.2)), underwent TAA by one surgeon. Preoperative and postoperative radiographs, Ankle Osteoarthritis Scale (AOS) pain and disability and 36-item Short Form Health Survey (SF-36) version 2 scores were collected prospectively. Ancillary procedures, secondary procedures, and complications were recorded.Aims
Methods
Functional rehabilitation has become an increasingly popular treatment for Achilles tendon rupture (ATR), providing comparably low re-rupture rates to surgery, while avoiding risks of surgical complications. Limited evidence exists on whether gap size should affect patient selection for this treatment option. The aim of this study was to assess if size of gap between ruptured tendon ends affects patient-reported outcome following ATR treated with functional rehabilitation. Analysis of prospectively collected data on all 131 patients diagnosed with ATR at Royal Berkshire Hospital, UK, from August 2016 to January 2019 and managed non-operatively was performed. Diagnosis was confirmed on all patients by dynamic ultrasound scanning and gap size measured with ankle in full plantarflexion. Functional rehabilitation using an established protocol was the preferred treatment. All non-operatively treated patients with completed Achilles Tendon Rupture Scores (ATRS) at a minimum of 12 months following injury were included.Aims
Methods
Arthroplasty for end-stage hallux rigidus (HR) is controversial. Arthrodesis remains the gold standard for surgical treatment, although is not without its complications, with rates of up to 10% for nonunion, 14% for reoperation and 10% for metatarsalgia. The aim of this study was to analyze the outcome of a double-stemmed silastic implant (Wright-Medical, Memphis, Tennessee, USA) for patients with end-stage HR. We conducted a retrospective review of 108 consecutive implants in 76 patients, between January 2005 and December 2016, with a minimum follow-up of two years. The mean age of the patients at the time of surgery was 61.6 years (42 to 84). There were 104 females and four males. Clinical, radiological, patient reported outcome measures (PROMS) data, a visual analogue score (VAS) for pain, and satisfaction scores were collected.Aims
Methods
The aim of this study was to evaluate the functional outcome in patients undergoing implant removal (IR) after fracture fixation below the level of the knee. All adult patients (18 to 75 years) undergoing IR after fracture fixation below the level of the knee between November 2014 and September 2016 were included as part of the WIFI (Wound Infections Following Implant Removal Below the Knee) trial, performed in 17 teaching hospitals and two university hospitals in The Netherlands. In this multicentre prospective cohort, the primary outcome was the difference in functional status before and after IR, measured by the Lower Extremity Functional Scale (LEFS), with a minimal clinically important difference of nine points.Aims
Patients and Methods
There is little information about how to manage patients with a recurvatum deformity of the distal tibia and osteoarthritis (OA) of the ankle. The aim of this study was to evaluate the functional and radiological outcome of addressing this deformity using a flexion osteotomy and to assess the progression of OA after this procedure. A total of 39 patients (12 women, 27 men; mean age 47 years (28 to 72)) with a distal tibial recurvatum deformity were treated with a flexion osteotomy, between 2010 and 2015. Nine patients (23%) subsequently required conversion to either a total ankle arthroplasty (seven) or an arthrodesis (two) after a mean of 21 months (9 to 36). A total of 30 patients (77%), with a mean follow-up of 30 months (24 to 76), remained for further evaluation. Functional outcome, sagittal ankle joint OA using a modified Kellgren and Lawrence Score, tibial lateral surface (TLS) angle, and talar offset ratio (TOR) were evaluated on pre- and postoperative weight-bearing radiographs.Aims
Patients and Methods
The purpose of this study was to determine the functional outcome and implant survivorship of mobile-bearing total ankle arthroplasty (TAA) performed by a single surgeon. We reviewed 205 consecutive patients (210 ankles) who had undergone mobile-bearing TAA (205 patients) for osteoarthritis of the ankle between January 2005 and December 2015. Their mean follow-up was 6.4 years (2.0 to 13.4). Functional outcome was assessed using the Ankle Osteoarthritis Scale, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, 36-Item Short-Form Health Survey (SF-36) score, visual analogue scale, and range of movement. Implant survivorship and complications were also evaluated.Aims
Patients and Methods
Total ankle arthroplasty (TAA) surgery is complex and attracts a wide variety of complications. The literature lacks consistency in reporting adverse events and complications. The aim of this article is to provide a comprehensive analysis of each of these complications from a literature review, and to compare them with rates from our Unit, to aid clinicians with the process of informed consent. A total of 278 consecutive total ankle arthroplasties (251 patients), performed by four surgeons over a six-year period in Wrightington Hospital (Wigan, United Kingdom) were prospectively reviewed. There were 143 men and 108 women with a mean age of 64 years (41 to 86). The data were recorded on each follow-up visit. Any complications either during initial hospital stay or subsequently reported on follow-ups were recorded, investigated, monitored, and treated as warranted. Literature search included the studies reporting the outcomes and complications of TAA implants.Aims
Patients and Methods
The incidence of acute Achilles tendon rupture appears to be increasing. The aim of this study was to summarize various therapies for acute Achilles tendon rupture and discuss their relative merits. A PubMed search about the management of acute Achilles tendon rupture was performed. The search was open for original manuscripts and review papers limited to publication from January 2006 to July 2017. A total of 489 papers were identified initially and finally 323 articles were suitable for this review.Objectives
Methods
We report the long-term clinical and radiological outcomes of a consecutive series of 200 total ankle arthroplasties (TAAs, 184 patients) at a single centre using the Scandinavian Total Ankle Replacement (STAR) implants. Between November 1993 and February 2000, 200 consecutive STAR prostheses were implanted in 184 patients by a single surgeon. Demographic and clinical data were collected prospectively and the last available status was recorded for further survival analysis. All surviving patients underwent regular clinical and radiological review. Pain and function were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot scoring system. The principal endpoint of the study was failure of the implant requiring revision of one or all of the components. Kaplan–Meier survival curves were generated with 95% confidence intervals and the rate of failure calculated for each year.Aims

This study reports the outcomes of a technique of soft-tissue coverage and Chopart amputation for severe crush injuries of the forefoot. Between January 2012 to December 2016, 12 patients (nine male; three female, mean age 38.58 years; 26 to 55) with severe foot crush injury underwent treatment in our institute. All patients were followed-up for at least one year. Their medical records, imaging, visual analogue scale score, walking ability, complications, and functional outcomes one year postoperatively based on the American Orthopedic Foot and Ankle Society (AOFAS) and 36-Item Short-Form Health Survey (SF-36) scores were reviewed.Aims

The aim of this retrospective study was to compare the functional
and radiological outcomes of bridge plating, screw fixation, and
a combination of both methods for the treatment of Lisfranc fracture
dislocations. A total of 108 patients were treated for a Lisfranc fracture
dislocation over a period of nine years. Of these, 38 underwent
transarticular screw fixation, 45 dorsal bridge plating, and 25
a combination technique. Injuries were assessed preoperatively according
to the Myerson classification system. The outcome measures included
the American Orthopaedic Foot and Ankle Society (AOFAS) score, the
validated Manchester Oxford Foot Questionnaire (MOXFQ) functional
tool, and the radiological Wilppula classification of anatomical
reduction.Aims

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

Flexor hallucis longus (FHL) tendon transfer is a well-recognized
technique in the treatment of the neglected tendo Achillis (TA)
rupture. We report a retrospective review of 20/32 patients who had undergone
transtendinous FHL transfer between 2003 and 2011 for chronic TA
rupture. Their mean age at the time of surgery was 53 years (22
to 83). The mean time from rupture to surgery was seven months (1
to 36). The mean postoperative follow-up was 73 months (29 to 120).
Six patients experienced postoperative wound complications.Aims
Patients and Methods
Lifestyle risk factors are thought to increase the risk of infection
after acute orthopaedic surgery but the evidence is scarce. We aimed
to investigate whether smoking, obesity and alcohol overuse are
risk factors for the development of infections after surgery for
a fracture of the ankle. We retrospectively reviewed all patients who underwent internal
fixation of a fracture of the ankle between 2008 and 2013. The primary
outcome was the rate of deep infection and the secondary outcome
was any surgical site infection (SSI). Associations with the risk
factors and possible confounding variables were analysed univariably
and multivariably with backwards elimination.Aims
Patients and Methods
The last decade has seen a considerable increase
in the use of in total ankle arthroplasty (TAA) to treat patients
with end-stage arthritis of the ankle. However, the longevity of
the implants is still far from that of total knee and hip arthroplasties. The aim of this review is to outline a diagnostic and treatment
algorithm for the painful TAA to be used when considering revision
surgery. Cite this article:
The aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures. Two types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared.Objectives
Methods
Limb salvage for diabetic foot infections often require multiple
procedures. Some patients will eventually end up with below knee
amputation (BKA) when all limb salvage attempts fail. We seek to
study the patients’ ability to return to normal life, functional
status, prosthesis usage and perspectives on multiple limb salvage
procedures that culminated in BKA to review if they would undertake
a similar path if their situation was repeated. A total of 41 patients who underwent BKA between July 2011 and
June 2013 were reviewed. They were divided into primary and creeping
(prior multiple salvage procedures) amputations. The Barthel’s Index
(BI) and the Reintegration to Normal Living Index (RNLI) were used.
A questionnaire was used to identify whether the patient would undergo
the same multiple attempts at limb salvage again if faced with the
same problem.Aims
Patients and Methods
The mainstay of surgical correction of hallux valgus is first
metatarsal osteotomy, either proximally or distally. We present
a technique of combining a distal chevron osteotomy with a proximal
opening wedge osteotomy, for the correction of moderate to severe
hallux valgus. We reviewed 45 patients (49 feet) who had undergone double osteotomy.
Outcome was assessed using the American Orthopaedic Foot and Ankle
Society (AOFAS) and the Short Form (SF) -36 Health Survey scores.
Radiological measurements were undertaken to assess the correction. The mean age of the patients was 60.8 years (44.2 to 75.3). The
mean follow-up was 35.4 months (24 to 51).Aims
Patients and Methods
A failed total ankle arthroplasty (TAA) is often associated with
much bone loss. As an alternative to arthrodesis, the surgeon may
consider a custom-made talar component to compensate for the bone
loss. Our aim in this study was to assess the functional and radiological
outcome after the use of such a component at mid- to long-term follow-up. A total of 12 patients (five women and seven men, mean age 53
years; 36 to77) with a failed TAA and a large talar defect underwent
a revision procedure using a custom-made talar component. The design
of the custom-made components was based on CT scans and standard
radiographs, when compared with the contralateral ankle. After the
anterior talocalcaneal joint was fused, the talar component was
introduced and fixed to the body of the calcaneum.Aims
Patients and Methods
The rate of surgical site infection after elective
foot and ankle surgery is higher than that after other elective orthopaedic
procedures. Since December 2005, we have prospectively collected data on
the rate of post-operative infection for 1737 patients who have
undergone elective foot and ankle surgery. In March 2008, additional
infection control policies, focused on surgical and environmental
risk factors, were introduced in our department. We saw a 50% reduction in the rate of surgical site infection
after the introduction of these measures. We are, however, aware
that the observed decrease may not be entirely attributable to these
measures alone given the number of factors that predispose to post-operative
wound infection. Cite this article:
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:
Patients with diabetes are at increased risk of wound complications
after open reduction and internal fixation of unstable ankle fractures.
A fibular nail avoids large surgical incisions and allows anatomical
reduction of the mortise. We retrospectively reviewed the results of fluoroscopy-guided
reduction and percutaneous fibular nail fixation for unstable Weber
type B or C fractures in 24 adult patients with type 1 or type 2
diabetes. The re-operation rate for wound dehiscence or other indications
such as amputation, mortality and functional outcomes was determined.Aims

Involvement of the posterior malleolus in fractures of the ankle
probably adversely affects the functional outcome and may be associated
with the development of post-traumatic osteoarthritis. Anatomical
reduction is a predictor of a successful outcome. The purpose of this study was to describe the technique and short-term
outcome of patients with trimalleolar fractures, who were treated
surgically using a posterolateral approach in our hospital between
2010 and 2014. The study involved 52 patients. Their mean age was 49 years (22
to 79). There were 41 (79%) AO 44B-type and 11 (21%) 44C-type fractures.
The mean size of the posterior fragment was 27% (10% to 52%) of
the tibiotalar joint surface.Aims

Charcot neuro-osteoarthropathy (CN) of the midfoot
presents a major reconstructive challenge for the foot and ankle
surgeon. The Synthes 6 mm Midfoot Fusion Bolt is both designed and
recommended for patients who have a deformity of the medial column
of the foot due to CN. We present the results from the first nine
patients (ten feet) on which we attempted to perform fusion of the
medial column using this bolt. Six feet had concurrent hindfoot fusion
using a retrograde nail. Satisfactory correction of deformity of
the medial column was achieved in all patients. The mean correction
of calcaneal pitch was from 6°
(-15° to +18°) pre-operatively to 16° (7° to 23°) post-operatively;
the mean Meary angle from 26° (3° to 46°) to 1° (1° to 2°); and
the mean talometatarsal angle on dorsoplantar radiographs from 27°
(1° to 48°) to 1° (1° to 3°). However, in all but two feet, at least one joint failed to fuse.
The bolt migrated in six feet, all of which showed progressive radiographic
osteolysis, which was considered to indicate loosening. Four of
these feet have undergone a revision procedure, with good radiological
evidence of fusion. The medial column bolt provided satisfactory correction
of the deformity but failed to provide adequate fixation for fusion
in CN deformities in the foot. In its present form, we cannot recommend the routine use of this
bolt. Cite this article:
The treatment of peri-prosthetic joint infection
(PJI) of the ankle is not standardised. It is not clear whether
an algorithm developed for hip and knee PJI can be used in the management
of PJI of the ankle. We evaluated the outcome, at two or more years
post-operatively, in 34 patients with PJI of the ankle, identified
from a cohort of 511 patients who had undergone total ankle replacement.
Their median age was 62.1 years (53.3 to 68.2), and 20 patients
were women. Infection was exogenous in 28 (82.4%) and haematogenous
in six (17.6%); 19 (55.9%) were acute infections and 15 (44.1%)
chronic. Staphylococci were the cause of 24 infections (70.6%).
Surgery with retention of one or both components was undertaken
in 21 patients (61.8%), both components were replaced in ten (29.4%),
and arthrodesis was undertaken in three (8.8%). An infection-free
outcome with satisfactory function of the ankle was obtained in
23 patients (67.6%). The best rate of cure followed the exchange
of both components (9/10, 90%). In the 21 patients in whom one or
both components were retained, four had a relapse of the same infecting organism
and three had an infection with another organism. Hence the rate
of cure was 66.7% (14 of 21). In these 21 patients, we compared
the treatment given to an algorithm developed for the treatment
of PJI of the knee and hip. In 17 (80.9%) patients, treatment was
not according to the algorithm. Most (11 of 17) had only one criterion against
retention of one or both components. In all, ten of 11 patients
with severe soft-tissue compromise as a single criterion had a relapse-free
survival. We propose that the treatment concept for PJI of the ankle
requires adaptation of the grading of quality of the soft tissues. Cite this article
Talonavicular and subtalar joint fusion through
a medial incision (modified triple arthrodesis) has become an increasingly
popular technique for treating symptomatic flatfoot deformity caused
by posterior tibial tendon dysfunction. The purpose of this study was to look at its clinical and radiological
mid- to long-term outcomes, including the rates of recurrent flatfoot
deformity, nonunion and avascular necrosis of the dome of the talus. A total of 84 patients (96 feet) with a symptomatic rigid flatfoot
deformity caused by posterior tibial tendon dysfunction were treated
using a modified triple arthrodesis. The mean age of the patients
was 66 years (35 to 85) and the mean follow-up was 4.7 years (1 to 8.3).
Both clinical and radiological outcomes were analysed retrospectively. In 86 of the 95 feet (90.5%) for which radiographs were available,
there was no loss of correction at final follow-up. In all, 14 feet
(14.7%) needed secondary surgery, six for nonunion, two for avascular
necrosis, five for progression of the flatfoot deformity and tibiotalar
arthritis and one because of symptomatic overcorrection. The mean
American Orthopaedic Foot and Ankle Society Hindfoot score (AOFAS
score) at final follow-up was 67 (between 16 and 100) and the mean
visual analogue score for pain 2.4 points (between 0 and 10). In conclusion, modified triple arthrodesis provides reliable
correction of deformity and a good clinical outcome at mid- to long-term
follow-up, with nonunion as the most frequent complication. Avascular
necrosis of the talus is a rare but serious complication of this
technique. 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:
Flexor digitorum longus transfer and medial displacement
calcaneal osteotomy is a well-recognised form of treatment for stage
II posterior tibial tendon dysfunction. Although excellent short-
and medium-term results have been reported, the long-term outcome
is unknown. We reviewed the clinical outcome of 31 patients with
a symptomatic flexible flat-foot deformity who underwent this procedure
between 1994 and 1996. There were 21 women and ten men with a mean
age of 54.3 years (42 to 70). The mean follow-up was 15.2 years
(11.4 to 16.5). All scores improved significantly (p <
0.001).
The mean American Orthopedic Foot and Ankle Society (AOFAS) score improved
from 48.4 pre-operatively to 90.3 (54 to 100) at the final follow-up.
The mean pain component improved from 12.3 to 35.2 (20 to 40). The
mean function score improved from 35.2 to 45.6 (30 to 50). The mean
visual analogue score for pain improved from 7.3 to 1.3 (0 to 6).
The mean Short Form-36 physical component score was 40.6 ( 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:
This study sought to determine the medium-term
patient-reported and radiographic outcomes in patients undergoing
surgery for hallux valgus. A total of 118 patients (162 feet) underwent
surgery for hallux valgus between January 2008 and June 2009. The
Manchester-Oxford Foot Questionnaire (MOXFQ), a validated tool for
the assessment of outcome after surgery for hallux valgus, was used
and patient satisfaction was sought. The medical records and radiographs
were reviewed retrospectively. At a mean of 5.2 years (4.7 to 6.0)
post-operatively, the median combined MOXFQ score was 7.8 (IQR:0
to 32.8). The median domain scores for pain, walking/standing, and social
interaction were 10 (IQR: 0 to 45), 0 (IQR: 0 to 32.1) and 6.3 (IQR:
0 to 25) respectively. A total of 119 procedures (73.9%, in 90 patients)
were reported as satisfactory but only 53 feet (32.7%, in 43 patients)
were completely asymptomatic. The mean (SD) correction of hallux
valgus, intermetatarsal, and distal metatarsal articular angles was
18.5° (8.8°), 5.7° (3.3°), and 16.6° (8.8°), respectively. Multivariable
regression analysis identified that an American Association of Anesthesiologists
grade of >
1 (Incident Rate Ratio (IRR) = 1.67, p-value = 0.011)
and recurrent deformity (IRR = 1.77, p-value = 0.003) were associated
with significantly worse MOXFQ scores. No correlation was found
between the severity of deformity, the type, or degree of surgical
correction and the outcome. When using a validated outcome score
for the assessment of outcome after surgery for hallux valgus, the
long-term results are worse than expected when compared with the
short- and mid-term outcomes, with 25.9% of patients dissatisfied
at a mean follow-up of 5.2 years. Cite this article:
In this randomised controlled trial, we evaluated
the role of elastic compression using ankle injury stockings (AIS)
in the management of fractures of the ankle. A total of 90 patients
with a mean age of 47 years (16 to 79) were treated within 72 hours
of presentation with a fracture of the ankle, 31 of whom were treated
operatively and 59 conservatively, were randomised to be treated
either with compression by AIS plus an Aircast boot or Tubigrip
plus an Aircast boot. Male to female ratio was 36:54. The primary
outcome measure was the functional Olerud–Molander ankle score (OMAS).
The secondary outcome measures were; the American Orthopaedic Foot
and Ankle Society score (AOFAS); the Short Form (SF)-12v2 Quality
of Life score; and the frequency of deep vein thrombosis (DVT). Compression using AIS reduced swelling of the ankle at all time
points and improved the mean OMAS score at six months to 98 (95%
confidence interval (CI) 96 to 99) compared with a mean of 67 (95%
CI 62 to 73) for the Tubigrip group (p <
0.001). The mean AOFAS
and SF-12v2 scores at six months were also significantly improved
by compression. Of 86 patients with duplex imaging at four weeks,
five (12%) of 43 in the AIS group and ten (23%) of 43 in the Tubigrip
group developed a DVT (p = 0.26). Compression improved functional outcome and quality of life following
fracture of the ankle. DVTs were frequent, but a larger study would
be needed to confirm that compression with AISs reduces the incidence
of DVT. 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:
We have evaluated the clinical effectiveness
of a metal resurfacing inlay implant for osteochondral defects of
the medial talar dome after failed previous surgical treatment.
We prospectively studied 20 consecutive patients with a mean age
of 38 years (20 to 60), for a mean of three years (2 to 5) post-surgery.
There was statistically significant reduction of pain in each of
four situations (i.e., rest, walking, stair climbing and running;
p ≤ 0.01). The median American Orthopaedic Foot and Ankle Society
ankle-hindfoot score improved from 62 (interquartile range (IQR)
46 to 72) pre-operatively to 87 (IQR 75 to 95) at final follow-up
(p <
0.001). The Foot and Ankle Outcome Score improved on all
subscales (p ≤ 0.03). The mean Short-Form 36 physical component
scale improved from 36 (23 to 50) pre-operatively to 45 (29 to 55)
at final follow-up (p = 0.001); the mental component scale did not
change significantly. On radiographs, progressive degenerative changes
of the opposing tibial plafond were observed in two patients. One
patient required additional surgery for the osteochondral defect.
This study shows that a metal implant is a promising treatment for
osteochondral defects of the medial talar dome after failed previous
surgery. Cite this article:
The Bologna–Oxford (BOX) total ankle replacement
(TAR) was developed with the aim of achieving satisfactory pain-free
movement of the ankle. To date, only one single multicentre study
has reported its clinical results. The aim of this study was to
conduct an independent review of its mid-term results. We retrospectively reviewed a total of 60 prospectively followed
patients in whom 62 BOX TARs had been implanted between 2004 and
2008. We used the American Orthopedic Foot and Ankle Society (AOFAS)
score to assess the clinical results. Standardised radiographs taken
at the time of final follow-up were analysed by two observers. The
overall survival was 91.9% at a mean follow-up of 42.5 months (24
to 71). The mean AOFAS score had improved from 35.1 points (
We analysed the clinical and radiological outcomes
of a new surgical technique for the treatment of heterozygote post-axial
metatarsal-type foot synpolydactyly with HOX-D13 genetic mutations
with a mean follow-up of 30.9 months (24 to 42). A total of 57 feet
in 36 patients (mean age 6.8 years (2 to 16)) were treated with
this new technique, which transfers the distal part of the duplicated
fourth metatarsal to the proximal part of the fifth metatarsal.
Clinical and radiological assessments were undertaken pre- and post-operatively
and any complications were recorded. Final outcomes were evaluated
according to the methods described by Phelps and Grogan. Forefoot width
was reduced and the lengths of the all reconstructed toes were maintained
after surgery. Union was achieved for all the metatarsal osteotomies
without any angular deformities. Outcomes at the final assessment
were excellent in 51 feet (89%) and good in six (11%). This newly
described surgical technique provides for painless, comfortable
shoe-wearing after a single, easy-to-perform operation with good
clinical, radiological and functional outcomes. Cite this article:
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).
A total of 80 patients with an acute rupture of tendo Achillis were randomised to operative repair using an open technique (39 patients) or non-operative treatment in a cast (41 patients). Patients were followed up for one year. Outcome measures included clinical complications, range of movement of the ankle, the Short Musculoskeletal Function Assessment (SMFA), and muscle function dynamometry evaluating dorsiflexion and plantar flexion of the ankle. The primary outcome measure was muscle dynamometry. Re-rupture occurred in two of 37 patients (5%) in the operative group and four of 39 (10%) in the non-operative group, which was not statistically significant (p = 0.68). There was a slightly greater range of plantar flexion and dorsiflexion of the ankle in the operative group at three months which was not statistically significant, but at four and six months the range of dorsiflexion was better in the non-operative group, although this did not reach statistically significance either. After 12 weeks the peak torque difference of plantar flexion compared with the normal side was less in the operative than the non-operative group (47% We were unable to show a convincing functional benefit from surgery for patients with an acute rupture of the tendo Achillis compared with conservative treatment in plaster.
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 osteomyelitis. Four patients (25%) had malunion. Fair, good or excellent ankle scores were found in 14 patients. External fixation with a ring fixator achieves stable reduction of the fractured fragments without additional trauma to soft tissues. With minimum complications and good healing results, the Ilizarov apparatus is particularly useful for high-energy pilon fractures.
