Lisfranc injuries were previously described as fracture-dislocations of the tarsometatarsal joints. With advancements in modern imaging, subtle Lisfranc injuries are now more frequently recognized, revealing that their true incidence is much higher than previously thought. Injury patterns can vary widely in severity and anatomy. Early diagnosis and treatment are essential to achieve good outcomes. The original classification systems were anatomy-based, and limited as tools for guiding treatment. The current review, using the best available evidence, instead introduces a stability-based classification system, with weightbearing radiographs and CT serving as key diagnostic tools. Stable injuries generally have good outcomes with nonoperative management, most reliably treated with immobilization and non-weightbearing for six weeks. Displaced or comminuted injuries require surgical intervention, with open reduction and internal fixation (ORIF) being the most common approach, with a consensus towards bridge plating. While ORIF generally achieves satisfactory results, its effectiveness can vary, particularly in high-energy injuries. Primary arthrodesis remains niche for the treatment of acute injuries, but may offer benefits such as lower rates of post-traumatic arthritis and hardware removal. Novel fixation techniques, including suture button fixation, aim to provide flexible stabilization, which theoretically could improve midfoot biomechanics and reduce complications. Early findings suggest promising functional outcomes, but further studies are required to validate this method compared with established techniques. Future research should focus on refining stability-based classification systems, validation of weightbearing CT, improving rehabilitation protocols, and optimizing surgical techniques for various injury patterns to ultimately enhance patient outcomes.

Tenosynovial giant cell tumour (TGCT) is one of the most common soft-tissue tumours of the foot and ankle and can behave in a locally aggressive manner. Tumour control can be difficult, despite the various methods of treatment available. Since treatment guidelines are lacking, the aim of this study was to review the multidisciplinary management by presenting the largest series of TGCT of the foot and ankle to date from two specialized sarcoma centres. The Oxford Tumour Registry and the Leiden University Medical Centre Sarcoma Registry were retrospectively reviewed for patients with histologically proven foot and ankle TGCT diagnosed between January 2002 and August 2019.Aims

The treatment of tibial aplasia is controversial. Amputation represents the gold standard with good functional results, but is frequently refused by the families. In these patients, treatment with reconstructive limb salvage can be considered. Due to the complexity of the deformity, this remains challenging and should be staged. The present study evaluated the role of femoro-pedal distraction using a circular external fixator in reconstructive treatment of tibial aplasia. The purpose of femoro-pedal distraction is to realign the limb and achieve soft tissue lengthening to allow subsequent reconstructive surgery. This was a retrospective study involving ten patients (12 limbs) with tibial aplasia, who underwent staged reconstruction. During the first operation a circular hexapod external fixator was applied and femoro-pedal distraction was undertaken over several months. Subsequent surgery included reconstruction of the knee joint and alignment of the foot.Aims
Methods
Fractures of the navicular can occur in isolation but, owing
to the intimate anatomical and biomechanical relationships, are
often associated with other injuries to the neighbouring bones and
joints in the foot. As a result, they can lead to long-term morbidity
and poor function. Our aim in this study was to identify patterns
of injury in a new classification system of traumatic fractures
of the navicular, with consideration being given to the commonly associated
injuries to the midfoot. We undertook a retrospective review of 285 consecutive patients
presenting over an eight- year period with a fracture of the navicular.
Five common patterns of injury were identified and classified according
to the radiological features. Type 1 fractures are dorsal avulsion
injuries related to the capsule of the talonavicular joint. Type
2 fractures are isolated avulsion injuries to the tuberosity of
the navicular. Type 3 fractures are a variant of tarsometatarsal
fracture/dislocations creating instability of the medial ray. Type
4 fractures involve the body of the navicular with no associated
injury to the lateral column and type 5 fractures occur in conjunction
with disruption of the midtarsal joint with crushing of the medial
or lateral, or both, columns of the foot.Aims
Patients and Methods
After the initial correction of congenital talipes equinovarus
(CTEV) using the Ponseti method, a subsequent dynamic deformity
is often managed by transfer of the tendon of tibialis anterior
(TATT) to the lateral cuneiform. Many surgeons believe the lateral
cuneiform should be ossified before surgery is undertaken. This
study quantifies the ossification process of the lateral cuneiform
in children with CTEV between one and three years of age. The length, width and height of the lateral cuneiform were measured
in 43 consecutive patients with unilateral CTEV who had been treated
using the Ponseti method. Measurements were taken by two independent
observers on standardised anteroposterior and lateral radiographs
of both feet taken at one, two and three years of age.Aims

To assess the effect of high tibial and distal femoral osteotomies
(HTO and DFO) on the pressure characteristics of the ankle joint. Varus and valgus malalignment of the knee was simulated in human
cadaver full-length legs. Testing included four measurements: baseline
malalignment, 5° and 10° re-aligning osteotomy, and control baseline
malalignment. For HTO, testing was rerun with the subtalar joint
fixed. In order to represent half body weight, a 300 N force was applied
onto the femoral head. Intra-articular sensors captured ankle pressure.Aims

To compare the structural durability of hydroxyapatite-tricalcium
phosphate (HATCP) to autologous iliac crest bone graft in calcaneal
lengthening osteotomy (CLO) for pes planovalgus in childhood. We present the interim results of ten patients (HATCP, n = 6
and autograft, n = 5) with a mean age of 11.5 years (8.2 to 14.2)
from a randomised controlled non-inferiority trial with six months
follow-up. The primary outcome was the stability of the osteotomy
as measured by radiostereometric analysis. A non-inferiority margin
of ≤ 2 mm osteotomy compression was set.Aims

Injuries to the foot in athletes are often subtle
and can lead to a substantial loss of function if not diagnosed
and treated appropriately. For these injuries in general, even after
a diagnosis is made, treatment options are controversial and become
even more so in high level athletes where limiting the time away
from training and competition is a significant consideration. In this review, we cover some of the common and important sporting
injuries affecting the foot including updates on their management
and outcomes. Cite this article:
Sporting injuries around the ankle vary from
simple sprains that will resolve spontaneously within a few days
to severe injuries which may never fully recover and may threaten
the career of a professional athlete. Some of these injuries can
be easily overlooked altogether or misdiagnosed with potentially
devastating effects on future performance. In this review article,
we cover some of the common and important sporting injuries involving

patients with cervical myelopathy who had undergone surgery. We hypothesised that all the indices correlate with each other,
but show slightly different recovery patterns, and that the newly
described JOACMEQ is a sensitive outcome measure.Aims

The aim of this study was to evaluate the feasibility
of using the intact S1 nerve root as a donor nerve to repair an avulsion
of the contralateral lumbosacral plexus. Two cohorts of patients
were recruited. In cohort 1, the L4–S4 nerve roots of 15 patients
with a unilateral fracture of the sacrum and sacral nerve injury
were stimulated during surgery to establish the precise functional
distribution of the S1 nerve root and its proportional contribution
to individual muscles. In cohort 2, the contralateral uninjured
S1 nerve root of six patients with a unilateral lumbosacral plexus
avulsion was transected extradurally and used with a 25 cm segment
of the common peroneal nerve from the injured leg to reconstruct
the avulsed plexus. The results from cohort 1 showed that the innervation of S1 in
each muscle can be compensated for by L4, L5, S2 and S3. Numbness
in the toes and a reduction in strength were found after surgery
in cohort 2, but these symptoms gradually disappeared and strength
recovered. The results of electrophysiological studies of the donor
limb were generally normal. Severing the S1 nerve root does not appear to damage the healthy
limb as far as clinical assessment and electrophysiological testing
can determine. Consequently, the S1 nerve can be considered to be
a suitable donor nerve for reconstruction of an avulsed contralateral
lumbosacral plexus. Cite this article:
Paediatric fractures are common and can cause
significant morbidity. Socioeconomic deprivation is associated with an
increased incidence of fractures in both adults and children, but
little is known about the epidemiology of paediatric fractures.
In this study we investigated the effect of social deprivation on
the epidemiology of paediatric fractures. We compiled a prospective database of all fractures in children
aged <
16 years presenting to the study centre. Demographics,
type of fracture, mode of injury and postcode were recorded. Socioeconomic
status quintiles were assigned for each child using the Scottish
Index for Multiple Deprivation (SIMD). We found a correlation between increasing deprivation and the
incidence of fractures (r = 1.00, p <
0.001). In the most deprived
group the incidence was 2420/100 000/yr, which diminished to 1775/100
000/yr in the least deprived group. The most deprived children were more likely to suffer a fracture
as a result of a fall (odds ratio (OR) = 1.5, p <
0.0001), blunt
trauma (OR = 1.5, p = 0.026) or a road traffic accident (OR = 2.7,
p <
0.0001) than the least deprived. These findings have important implications for public health
and preventative measures. Cite this article:
In this study we evaluated the results of midtarsal
release and open reduction for the treatment of children with convex
congenital foot (CCF) (vertical talus) and compared them with the
published results of peritalar release. Between 1977 and 2009, a
total of 22 children (31 feet) underwent this procedure. In 15 children
(48%) the CCF was isolated and in the remainder it was not (seven
with arthrogryposis, two with spinal dysraphism, one with a polymalformative
syndrome and six with an undefined neurological disorder). Pre-operatively, the mean tibiotalar angle was 150.2° (106° to
175°) and the mean calcaneal pitch angle was -19.3° (-72° to 4°).
The procedure included talonavicular and calcaneocuboid joint capsulotomies,
lengthening of tendons of tibialis anterior and the extensors of
the toes, allowing reduction of the midtarsal joints. Lengthening
of the Achilles tendon was necessary in 23 feet (74%). The mean follow-up was 11 years (2 to 21). The results, as assessed
by the Adelaar score, were good in 24 feet (77.4%), fair in six
(19.3%) and poor in one foot (3.3%), with no difference between
those with isolated CCF and those without. The mean American Orthopaedic
Foot and Ankle Society midfoot score was 89.9 (54 to 100) and 77.8
(36 to 93) for those with isolated CCF and those without, respectively.
At the final follow-up, the mean tibiotalar (120°; 90 to 152) and
calcaneal pitch angles (4°; -13 to 22) had improved significantly
(p <
0.0001). Dislocation of the talonavicular and calcaneocuboid
joints was completely reduced in 22 (70.9%) and 29 (93.6%) of feet,
respectively. Three children (five feet) underwent further surgery
at a mean of 8.5 years post-operatively, three with pes planovalgus
and two in whom the deformity had been undercorrected. No child
developed avascular necrosis of the talus. Midtarsal joint release and open reduction is a satisfactory
procedure, which may provide better results than peritalar release.
Complications include the development of pes planovalgus and persistent
dorsal subluxation of the talonavicular joint. Cite this article:
Giant cell tumours (GCTs) of the small bones
of the hands and feet are rare. Small case series have been published but
there is no consensus about ideal treatment. We performed a systematic
review, initially screening 775 titles, and included 12 papers comprising
91 patients with GCT of the small bones of the hands and feet. The
rate of recurrence across these publications was found to be 72%
(18 of 25) in those treated with isolated curettage, 13% (2 of 15)
in those treated with curettage plus adjuvants, 15% (6 of 41) in
those treated by resection and 10% (1 of 10) in those treated by
amputation. We then retrospectively analysed 30 patients treated for GCT
of the small bones of the hands and feet between 1987 and 2010 in
five specialised centres. The primary treatment was curettage in
six, curettage with adjuvants (phenol or liquid nitrogen with or
without polymethylmethacrylate (PMMA)) in 18 and resection in six.
We evaluated the rate of complications and recurrence as well as
the factors that influenced their functional outcome. At a mean follow-up of 7.9 years (2 to 26) the rate of recurrence
was 50% (n = 3) in those patients treated with isolated curettage,
22% (n = 4) in those treated with curettage plus adjuvants and 17%
(n = 1) in those treated with resection (p = 0.404). The only complication
was pain in one patient, which resolved after surgical removal of remnants
of PMMA. We could not identify any individual factors associated
with a higher rate of complications or recurrence. The mean post-operative
Musculoskeletal Tumor Society scores were slightly higher after
intra-lesional treatment including isolated curettage and curettage
plus adjuvants (29 (20 to 30)) compared with resection (25 (15 to
30)) (p = 0.091). Repeated curettage with adjuvants eventually resulted
in the cure for all patients and is therefore a reasonable treatment
for both primary and recurrent GCT of the small bones of the hands
and feet. Cite this article:
The purpose of this study was to compare the
results of proximal and distal chevron osteotomy in patients with moderate
hallux valgus. We retrospectively reviewed 34 proximal chevron osteotomies without
lateral release (PCO group) and 33 distal chevron osteotomies (DCO
group) performed sequentially by a single surgeon. There were no
differences between the groups with regard to age, length of follow-up,
demographic or radiological parameters. The clinical results were
assessed using the American Orthopaedic Foot and Ankle Society (AOFAS)
scoring system and the radiological results were compared between
the groups. At a mean follow-up of 14.6 months (14 to 32) there were no significant
differences in the mean AOFAS scores between the DCO and PCO groups
(93.9 (82 to 100) and 91.8 (77 to 100), respectively; p = 0.176).
The mean hallux valgus angle, intermetatarsal angle and sesamoid
position were the same in both groups. The metatarsal declination
angle decreased significantly in the PCO group (p = 0.005) and the
mean shortening of the first metatarsal was significantly greater
in the DCO group (p <
0.001). We conclude that the clinical and radiological outcome after
a DCO is comparable with that after a PCO; longer follow-up would
be needed to assess the risk of avascular necrosis. Cite this article:
At our institution surgical correction of symptomatic
flat foot deformities in children has been guided by a paradigm in
which radiographs and pedobarography are used in the assessment
of outcome following treatment. Retrospective review of children
with symptomatic flat feet who had undergone surgical correction
was performed to assess the outcome and establish the relationship
between the static alignment and the dynamic loading of the foot. A total of 17 children (21 feet) were assessed before and after
correction of soft-tissue contractures and lateral column lengthening,
using standardised radiological and pedobarographic techniques for
which normative data were available. We found significantly improved static segmental alignment of
the foot, significantly improved mediolateral dimension foot loading,
and worsened fore-aft foot loading, following surgical treatment.
Only four significant associations were found between radiological
measures of static segmental alignment and dynamic loading of the foot. Weakness of the plantar flexors of the ankle was a common post-operative
finding. Surgeons should be judicious in the magnitude of lengthening
of the plantar flexors that is undertaken and use techniques that
minimise subsequent weakening of this muscle group. Cite this article:
This pilot study analysed the outcome of open The mean age of the patients was 22.9 years (18 to 28) and the
mean follow-up was 28.7 months (24 to 36). There were no statistically
significant differences in regard to age of patients, cyst size
and the follow-up periods in the two groups. The operating time
and mean length of stay of group 2 patients was significantly shorter
than group 1 patients (p <
0.001). The time to healing was similar
in the two groups. The overall success rates for groups 1 and 2 were
92.3% (12 of 13) and 100% (13 of 13), respectively, and there were
no statistically significant differences regarding radiological
healing. This pilot study suggests that endoscopic curettage and
percutaneous grafting is a simple and safe form of treatment, with
similar results to those following open treatment.
