Nineteen patients with chronic pain due to a traumatic
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:
To our knowledge, there is currently no information available about the rate of venous thromboembolism (VTE) or recommendations regarding chemoprophylaxis for patients whose lower limb is immobilized in a plaster cast. We report a retrospective case series assessing the rate of symptomatic VTE in patients treated with a lower limb cast. Given the complex, heterogeneous nature of this group of patients, with many risk factors for VTE, we hypothesized that the rate of VTE would be higher than in the general population. Patients treated with a lower limb cast between 2006 and 2018 were identified using plaster room records. Their electronic records and radiological reports were reviewed for details about their cast, past medical history, and any VTE recorded in our hospital within a year of casting.Aims

Ceramic-on-ceramic (CoC) articulations in total hip arthroplasty (THA) have low wear, but the unique risk of fracture. After revision for CoC fracture, ceramic third bodies can lead to runaway wear of cobalt chrome (CoCr) causing extremely elevated blood cobalt. We present five cases of ceramic liner fractures revised to a CoCr head associated with the rapid development of severe cobalt toxicity. We identified 5 cases of fractured CoC THA treated with revision to CoCr on highly cross-linked polyethylene (HXLPE) – three to conventional bearings and two to modular dual mobility bearings (CoCr acetabular liner, CoCr femoral head, and HXLPE). Mean follow up was 2.5 years after CoCr/HXLPE re-revision. Symptoms of cobalt toxicity occurred at average 9.5 months after revision for ceramic fracture (range 6–12). All patients developed vision and hearing loss, balance difficulties, and
Percutaneous flexor tenotomy involves cutting the flexor digitorum tendons to correct claw toe deformity to treat apical pressure areas and prevent subsequent infection in patients with
Introduction. Charcot neuroarthropathy (CN) of foot and ankle presents significant challenges to the orthopaedic foot and ankle surgeon. Current treatment focuses on conservative management during the acute CN phase with offloading followed by deformity correction during the chronic phase. However, the deformity can progress in some feet despite optimal offloading resulting ulceration, infection, and limb loss. Our aim was to assess outcomes of primary surgical management with early reconstruction. Methods. Between December 2011 and December 2019, 25 patients underwent operative intervention at our specialist diabetic foot unit for CN with progressive deformity and or instability despite advanced offloading. All had
Introduction. Circular frames for ankle fusion are usually reserved for complex clinical scenarios. Current literature is heterogenous and difficult to interpret. We aimed to study the indications and outcomes of this procedure in detail. Materials & Methods. A retrospective cohort study was performed based on a prospective database of frame surgeries performed in a tertiary institution. Inclusion criteria were patients undergoing complex ankle fusion with circular frames between 2005 and 2020, with a minimum 12-month follow up. Data were collected on patient demographics, surgical indications, comorbidities, surgical procedures, external fixator time (EFT), length of stay (LOS), radiological and clinical outcomes, and adverse events. Factors influencing radiological and clinical outcomes were analysed. Results. 47 patients were included, with a mean follow-up of three years. The mean age at time of surgery was 63.6 years. Patients had a median of two previous surgeries. The median LOS was 8.5 days, and median EFT was 237 days. Where simultaneous limb lengthening was performed, the average lengthening was 2.9cm, increasing the EFT by an average of 4 months. Primary and final union rates were 91.5% and 95.7% respectively. At last follow-up, ASAMI bone scores were excellent or good in 87.2%. ASAMI functional scores were good in 79.1%. Patient satisfaction was 83.7%. 97.7% of patients experienced adverse events, most commonly pin-site related, with major complications in 30.2% and re-operations in 60.5%. There were 3 amputations. Adverse events were associated with increased age, poor soft tissue condition, severe deformities, subtalar fusions,
Between 2000 and 2006 we performed salvage tibiotalar arthrodesis in 17 diabetic patients (17 ankles) with grossly unstable ankles caused by bimalleolar fractures complicated by Charcot neuro-arthropathy. There were ten women and seven men with a mean age of 61.6 years (57 to 69). A crossed-screw technique was used. Two screws were used in eight patients and three screws in nine. Additional graft from the malleoli was used in all patients. The mean follow-up was 26 months (12 to 48) and the mean time to union was 5.8 months (4 to 8). A stable ankle was achieved in 14 patients (82.4%), nine of whom had bony fusion and five had a stiff fibrous union. The results were significantly better in underweight patients, in those in whom surgery had been performed three to six months after the onset of acute Charcot arthropathy, in those who had received anti-resorptive medication during the acute stage, in those without extensive
Introduction. Hindfoot surgery is assumed to be more painful than midfoot/forefoot procedures with the former often requiring an inpatient stay for pain relief. Poorly controlled pain is associated with adverse patient outcomes and consequently, peripheral nerve blocks (PNB) have become popular for their effective pain control. Aim. To investigate whether hindfoot procedures are more painful than forefoot/midfoot procedures by measuring pain scores, assessing effectiveness of PNBs and patient satisfaction in foot and ankle surgery. Method. In total 140 patients were prospectively studied. Inclusion criteria: Adults undergoing elective foot and ankle surgery. Exclusion criteria: Paediatric patients 16 years and under, those with alternate sources of pain,
Introduction. Regional anesthesia is commonly utilized to minimize postoperative pain, improve function, and allow earlier rehabilitation following Total Knee Arthroplasty (TKA). The adductor canal block (ACB) provides effective analgesia of the anterior knee. However, patients will often experience posterior pain not covered by the ACB requiring supplemental opioid medications. A technique involving infiltration of local anesthetic between the popliteal artery and capsule of knee (IPACK) targets the terminal branches of the sciatic nerve, providing an alternative for controlling posterior knee pain following TKA. Materials and Methods. IRB approval was obtained, a power analysis was performed, and all patients gave informed consent. Eligible patients were those scheduled for an elective unilateral, primary TKA, who were ≥ 18 years old, English speaking, American Society of Anesthesiologists physical status (ASA PS) classification I-III. Exclusion criteria included contraindication to regional anesthesia or peripheral nerve blocks, allergy to local anesthetics, allergy to nonsteroidal anti-inflammatory drugs (NSAIDs), chronic renal insufficiency with GFR < 60, chronic pain not related to the operative joint, chronic (> 3 month) opioid use, pre-existing

There are numerous causes of cavovarus feet, the most common of which are the hereditary motor and sensory
Nerve damage is a complication of THA and TKA procedures. The incidence of subclinical nerve injury following arthroplasty is unknown. The aim was to determine the prevalence of asymptomatic nerve deficits in an arthroplasty population group, and the incidence of post-operative changes in nerve function. A Secondary aim was to identify the nature of any deficits. And the association between nerve deficits and history of backache. A non-randomised prospective series of patients undergoing lower limb arthroplasty for osteoarthritis were studied at a single hospital. The peroneal nerve was investigated using nerve conduction in forty patients. Twenty patients had upper limb testing to differentiate between a polyneuropathy or isolated lower limb neuropathy. Nerve function deficits were detected in the peroneal nerve in fifteen patients pre-operatively and fifteen post-operatively, of those twelve had A waves detected suggestive of a generalised neuropathy. Ten patients who had upper limb testing had a conduction defect (five had asymptomatic Carpal tunnel). There was a positive correlation between presence of post-operative deficit and age(r=0.389, p=0.013). A negative correlation was found for presence of post-operative A waves and BMI(r=−0.370, p=0.019). The prevalence of pre-operative subclinical peroneal neuropathy is much higher than expected in this group (37.5%) of arthroplasty patients. There is a strong correlation between presence of post-operative conduction abnormalities and age. There is no relationship between

Introduction:. Charcot arthropathy is a complex condition affecting diabetic patients with neuropathy. Diagnosis of acute Charcot arthropathy particularly in absence of any perceptible trauma is very challenging as clinically it can mimic osteomyelitis and cellulitis. Delay in recognition of Charcot arthropathy can result in gross instability of foot and ankle. Early diagnosis can provide an opportunity to halt the progression of disease. We report the role of SPECT /CT in the early diagnosis and elucidation of the natural progression of the disease. Methods:. Our multidisciplinary team analysed the scans of neuropathic patients presented with acute red, hot, swollen foot with normal radiological findings (Eichenholtz stage 0), attending the diabetic foot clinic from 2009–2013. The patients were selected from our database, clinic and nuclear medicine records. Initial workup included the assessment of
Background and objective. Metatarsals stress fractures are common in athletes and dancers. Occasionally, such fractures could occur without trauma in peripheral neuropathic patients. There is no published series describing outcome of stress fractures in these patients. This study analyse these fractures, treatment and outcome. Material and Method. Retrospective study, January 2005 to December 2010. From a total of 324 patients with metatarsal fractures, 8 patients with
The aim of this project was to look at time taken to achieve clinical resolution of diabetic charcot neuroarthropathy (CN) and to see if there was a correlation with location within the foot and overall outcomes. A retrospective analysis of newly presenting acute CN patients between 2007 & 2012 was performed. Clinic records were examined to determine the site of the CN; total time treated in a TCC or other removable offloading devices; the presence of co-morbidities. Fifty CN cases presented during this time. The mean age was 62.5±11.7 (SD) years. Eleven patients had type 1 diabetes mellitus (T1DM). The mean duration of diabetes was 29.7±12.9 years for T1DM, and 14.4±10.7 years for type 2 diabetics. All had palpable foot pulses &
Background:. Calcaneal osteotomy is an established technique in correcting hind foot deformity. Patients have traditionally received an open osteotomy through Atkins lateral approach. In order to reduce the rate of wound complications associated with the Atkins approach, a minimally invasive surgical (MIS) technique has been adopted since 2011. This uses a low-speed, high-torque burr to perform the same osteotomy under radiographic guidance. The results of the new MIS technique, including post-operative complication rates, are compared to the standard open approach. Methods:. The safety of the new MIS technique was investigated by conducting a case controlled study on all patients who underwent displacement calcaneal osteotomy at the Nuffield Orthopaedic Centre, Oxford from 2008 to 2014. The primary outcome measure was 30 day post-operative complication rate. Secondary outcome measures included operating time, duration of stay, fusion rates and amount of displacement achieved. Results:. 82 patients underwent calcaneal osteotomy as part of their corrective surgery; 50 patients in the Open approach group and 32 patients in MIS group. The average age at the time of surgery was 47.7 years (range 16–77) for the Open group and 48.5 (range 21–77) in the MIS group. A mean calcaneal displacement of 8.0mm (s.d. 1.32, 7 to 11 mm) and 8.33mm (s.d.1.53, 6 to 10 mm) was achieved through the MIS and open approaches respectively. There were significantly fewer wound complications in the MIS group (6.25%) compared to the Open group (28%, P=0.021) and the MIS group was associated with significantly lower rates of wound infection (3% versus 20%, P = 0.043). Three patients in the Open group experienced sural
Background: Radicular pain has been reported even in the absence of a compressive lesion. It has been postulated that annular tears provide a conduit for pro-inflammatory substances, which can leak around the nerve root causing radiculitis. A link between the side of back pain and the side of the annular tear has been reported. Objective: To establish whether the side of the annular tear may influence the side of the leg in a non-compressive setting. Methods and patients: We identified 121 patients from the patients referred to our unit with back and radicular leg pain. The mean age of the cohort was 50 yrs and 49% were male. All these patients were investigated with an MRI scan that demonstrated no compression of the nerve root. We used strict exclusion criteria to exclude the patients with any neural compression, previous lumbar operation, degenerative deformity or an associated pathology such as
Background. Patients with diabetes who sustain an ankle fracture are at increased risk for complications including higher rates of in-hospital mortality, in-hospital post-operative complications, length of stay and non-routine discharges. Aim. The purpose of this study was to retrospectively compare the complications associated with operatively treated ankle fractures in a group of patients with uncomplicated diabetes versus a group of patients with complicated diabetes. Complicated diabetes was defined as diabetes associated with end organ damage such as
