The aim of this retrospective cohort study was to assess and investigate the safety and efficacy of using a distal tibial osteotomy compared to proximal osteotomy for limb lengthening in children. In this study, there were 59 consecutive tibial lengthening and deformity corrections in 57 children using a circular frame. All were performed or supervised by the senior author between January 2013 and June 2019. A total of 25 who underwent a distal tibial osteotomy were analyzed and compared to a group of 34 who had a standard proximal tibial osteotomy. For each patient, the primary diagnosis, time in frame, complications, and lengthening achieved were recorded. From these data, the frame index was calculated (days/cm) and analyzed.Aims
Methods
Many authors have reported a shorter treatment time when using trifocal bone transport (TFT) rather than bifocal bone transport (BFT) in the management of long segmental tibial bone defects. However, the difference in the incidence of additional procedures, the true complications, and the final results have not been investigated. A total of 86 consecutive patients with a long tibial bone defect (≥ 8 cm), who were treated between January 2008 and January 2015, were retrospectively reviewed. A total of 45 were treated by BFT and 41 by TFT. The median age of the 45 patients in the BFT group was 43 years (interquartile range (IQR) 23 to 54).Aims
Patients and Methods
The aim of this study was to report the clinical, functional
and radiological outcomes of children and adolescents with tibial
fractures treated using the Ilizarov method. Between 2013 and 2016 a total of 74 children with 75 tibial fractures
underwent treatment at our major trauma centre using an Ilizarov
frame. Demographic and clinical information from a prospective database
was supplemented by routine functional and psychological assessment
and a retrospective review of the notes and radiographs.Aims
Patients and Methods
Our aim was to examine the clinical and radiographic outcomes
in 257 consecutive Oxford unicompartmental knee arthroplasties (OUKAs)
(238 patients), five years post-operatively. A retrospective evaluation was undertaken of patients treated
between April 2008 and October 2010 in a regional centre by two
non-designing surgeons with no previous experience of UKAs. The
Oxford Knee Scores (OKSs) were recorded and fluoroscopically aligned
radiographs were assessed post-operatively at one and five years.Aims

Infected nonunion of a long bone continues to
present difficulties in management. In addition to treating the infection,
it is necessary to establish bony stability, encourage fracture
union and reconstruct the soft-tissue envelope. We present a series of 67 infected nonunions of a long bone in
66 patients treated in a multidisciplinary unit. The operative treatment
of patients suitable for limb salvage was performed as a single
procedure. Antibiotic regimes were determined by the results of
microbiological culture. At a mean follow-up of 52 months (22 to 97), 59 patients (88%)
had an infection-free united fracture in a functioning limb. Seven
others required amputation (three as primary treatment, three after
late failure of limb salvage and one for recalcitrant pain after
union). The initial operation achieved union in 54 (84%) of the salvaged
limbs at a mean of nine months (three to 26), with recurrence of
infection in 9%. Further surgery in those limbs that remained ununited
increased the union rate to 62 (97%) of the 64 limbs treated by
limb salvage at final follow-up. The use of internal fixation was
associated with a higher risk of recurrent infection than external
fixation. 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:
We report the effect of introducing a dedicated
Ponseti service on the five-year treatment outcomes of children
with idiopathic clubfoot. Between 2002 and 2004, 100 feet (66 children; 50 boys and 16
girls) were treated in a general paediatric orthopaedic clinic.
Of these, 96 feet (96%) responded to initial casting, 85 requiring
a tenotomy of the tendo-Achillis. Recurrent deformity occurred in
38 feet and was successfully treated in 22 by repeat casting and/or
tenotomy and/or transfer of the tendon of tibialis anterior, The
remaining 16 required an extensive surgical release. Between 2005 and 2006, 72 feet (53 children; 33 boys and 20 girls)
were treated in a dedicated multidisciplinary Ponseti clinic. All
responded to initial casting: 60 feet (83.3%) required a tenotomy
of the tendo-Achillis. Recurrent deformity developed in 14, 11 of
which were successfully treated by repeat casting and/or tenotomy
and/or transfer of the tendon of tibialis anterior. The other three
required an extensive surgical release. Statistical analysis showed that children treated in the dedicated
Ponseti clinic had a lower rate of recurrence (p = 0.068) and a
lower rate of surgical release (p = 0.01) than those treated in
the general clinic. This study shows that a dedicated Ponseti clinic, run by a well-trained
multidisciplinary team, can improve the outcome of idiopathic clubfoot
deformity. Cite this article:
Unstable bicondylar tibial plateau fractures
are rare and there is little guidance in the literature as to the
best form of treatment. We examined the short- to medium-term outcome
of this injury in a consecutive series of patients presenting to
two trauma centres. Between December 2005 and May 2010, a total
of 55 fractures in 54 patients were treated by fixation, 34 with
peri-articular locking plates and 21 with limited access direct
internal fixation in combination with circular external fixation
using a Taylor Spatial Frame (TSF). At a minimum of one year post-operatively,
patient-reported outcome measures including the WOMAC index and
SF-36 scores showed functional deficits, although there was no significant
difference between the two forms of treatment. Despite low outcome scores,
patients were generally satisfied with the outcome. We achieved
good clinical and radiological outcomes, with low rates of complication.
In total, only three patients (5%) had collapse of the joint of
>
4 mm, and metaphysis to diaphysis angulation of greater than 5º,
and five patients (9%) with displacement of >
4 mm. All patients
in our study went on to achieve full union. This study highlights the serious nature of this injury and generally
poor patient-reported outcome measures following surgery, despite
treatment by experienced surgeons using modern surgical techniques.
Our findings suggest that treatment of complex bicondylar tibial
plateau fractures with either a locking plate or a TSF gives similar
clinical and radiological outcomes. Cite this article:
The treatment of chronic osteomyelitis often
includes surgical debridement and filling the resultant void with antibiotic-loaded
polymethylmethacrylate cement, bone grafts or bone substitutes.
Recently, the use of bioactive glass to treat bone defects in infections
has been reported in a limited series of patients. However, no direct comparison
between this biomaterial and antibiotic-loaded bone substitute has
been performed. In this retrospective study, we compared the safety and efficacy
of surgical debridement and local application of the bioactive glass
S53P4 in a series of 27 patients affected by chronic osteomyelitis
of the long bones (Group A) with two other series, treated respectively
with an antibiotic-loaded hydroxyapatite and calcium sulphate compound
(Group B; n = 27) or a mixture of tricalcium phosphate and an antibiotic-loaded
demineralised bone matrix (Group C; n = 22). Systemic antibiotics
were also used in all groups. After comparable periods of follow-up, the control of infection
was similar in the three groups. In particular, 25 out of 27 (92.6%)
patients of Group A, 24 out of 27 (88.9%) in Group B and 19 out
of 22 (86.3%) in Group C showed no infection recurrence at means
of 21.8 (12 to 36), 22.1 (12 to 36) and 21.5 (12 to 36) months follow-up,
respectively, while Group A showed a reduced wound complication
rate. Our results show that patients treated with a bioactive glass
without local antibiotics achieved similar eradication of infection
and less drainage than those treated with two different antibiotic-loaded
calcium-based bone substitutes. Cite this article:
Recent recommendations by the National Institute
for Health and Care Excellence (NICE) suggest that all patients undergoing
elective orthopaedic surgery should be assessed for the risk of
venous thromboembolism (VTE). Little is known about the incidence of symptomatic VTE after
elective external fixation. We studied a consecutive series of adult
patients who had undergone elective Ilizarov surgery without routine
pharmacological prophylaxis to establish the incidence of symptomatic
VTE. A review of a prospectively maintained database of consecutive
patients who were treated between October 1998 and February 2011
identified 457 frames in 442 adults whose mean age was 42.6 years
(16.0 to 84.6). There were 425 lower limb and 32 upper limb frames.
The mean duration of treatment was 25.7 weeks (1.6 to 85.3). According to NICE guidelines all the patients had at least one
risk factor for VTE, 246 had two, 172 had three and 31 had four
or more. One patient (0.23%) developed a pulmonary embolus after surgery
and was later found to have an inherited thrombophilia. There were
27 deaths, all unrelated to VTE. The cost of providing VTE prophylaxis according to NICE guidelines
in this group of patients would be £89 493.40 (£195.80 per patient)
even if the cheapest recommended medication was used. The rate of symptomatic VTE after Ilizarov surgery was low despite
using no pharmacological prophylaxis. This study leads us to question
whether NICE guidelines are applicable to these patients. 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 report on the use of the Ilizarov method to
treat 40 consecutive fractures of the tibial shaft (35 AO 42C fractures and
five AO 42B3 fractures) in adults. There were 28 men and
12 women with a mean age of 43 years (19 to 81). The series included
19 open fractures (six Gustilo grade 3A and 13 grade 3B) and 21
closed injuries. The mean time from injury to application of definitive
Ilizarov frame was eight days (0 to 35) with 36 fractures successfully
uniting without the need for any bone-stimulating procedure. The
four remaining patients with nonunion healed with a second frame.
There were no amputations and no deep infections. None required
intervention for malunion. The total time to healing was calculated
from date of injury to removal of the frame, with a median of 166
days (mean 187, (87 to 370)). Minor complications included snapped
wires in two patients and minor pin-site infections treated with
oral antibiotics in nine patients (23%). Clinical scores were available
for 32 of the 40 patients at a median of 55 months (mean 62, (26
to 99)) post-injury, with ‘good’ Olerud and Molander ankle scores
(median 80, mean 75, (10 to 100)), ‘excellent’ Lysholm knee scores
(median 97, mean 88, (29 to 100)), a median Tegner activity score
of 4 (mean 4, (0 to 9)) (comparable to ‘moderately heavy labour
/ cycling and jogging’) and Short Form-12 scores that exceeded the
mean of the population as a whole (median physical component score
55 (mean 51, (20 to 64)), median mental component score 57 (mean
53, (21 to 62)). In conclusion, the Ilizarov method is a safe and
reliable way of treating complex tibial shaft fractures with a high
rate of primary union.
We undertook a retrospective analysis of 306
procedures on 233 patients, with a mean age of 12 years (1 to 21),
in order to evaluate the use of somatosensory evoked potential (SSEP)
monitoring for the early detection of nerve compromise during external
fixation procedures for limb lengthening and correction of deformity.
Significant SSEP changes were identified during 58 procedures (19%).
In 32 instances (10.5%) the changes were transient, and resolved
once the surgical cause had been removed. The remaining 26 (8.5%)
were analysed in two groups, depending on whether or not corrective
action had been performed in response to critical changes in the
SSEP recordings. In 16 cases in which no corrective action was taken,
13 (81.2%, 4.2% overall) developed a post-operative neurological
deficit, six of which were permanent and seven temporary, persisting
for five to 18 months. In the ten procedures in which corrective
action was taken, four patients (40%, 1.3% overall) had a temporary
(one to eight months) post-operative neuropathy and six had no deficit. After appropriate intervention in response to SSEP changes, the
incidence and severity of neurological deficits were significantly
reduced, with no cases of permanent neuropathy. SSEP monitoring
showed 100% sensitivity and 91% specificity for the detection of
nerve injury during external fixation. It is an excellent diagnostic
technique for identifying nerve lesions when they are still highly
reversible.
We describe three cases of infantile tibia vara
resulting from an atraumatic slip of the proximal tibial epiphysis
upon the metaphysis. There appears to be an association between
this condition and severe obesity. Radiologically, the condition
is characterised by a dome-shaped metaphysis, an open growth plate
and disruption of the continuity between the lateral borders of
the epiphysis and metaphysis, with inferomedial translation of the
proximal tibial epiphysis. All patients were treated by realignment
of the proximal tibia by distraction osteogenesis with an external
circulator fixator, and it is suggested that this is the optimal
method for correction of this complex deformity. There are differences
in the radiological features and management between conventional
infantile Blount’s disease and this ‘slipped upper tibial epiphysis’
variant.
In distal fibular resection without reconstruction,
the stabilising effect of the lateral malleolus is lost. Thus, the ankle
may collapse into valgus and may be unstable in varus. Here, we
describe a child who underwent successful staged surgical correction
of a severe neglected valgus deformity after excision of the distal
fibula for a Ewing’s sarcoma.
