Rotator cuff tears are common in middle-aged and elderly patients. Despite advances in the surgical repair of rotator cuff tears, the rates of recurrent tear remain high. This may be due to the complexity of the tendons of the rotator cuff, which contributes to an inherently hostile healing environment. During the past 20 years, there has been an increased interest in the use of biologics to complement the healing environment in the shoulder, in order to improve rotator cuff healing and reduce the rate of recurrent tears. The aim of this review is to provide a summary of the current evidence for the use of forms of biological augmentation when repairing rotator cuff tears. Cite this article:

Musculoskeletal infection is a devastating complication in both trauma and elective orthopaedic surgeries that can result in significant morbidity. Aim of this study was to assess the effectiveness and complications of local antibiotic impregnated dissolvable synthetic calcium sulphate beads (Stimulan Rapid Cure) in the hands of different surgeons from multiple centres in surgically managed bone and joint infections. Between January 2019 and December 2022, 106 patients with bone and joint infections were treated by five surgeons in five hospitals. Surgical debridement and calcium sulphate bead insertion was performed for local elution of antibiotics in high concentration. In all, 100 patients were available for follow-up at regular intervals. Choice of antibiotic was tailor made for each patient in consultation with microbiologist based on the organism grown on culture and the sensitivity. In majority of our cases, we used a combination of vancomycin and culture sensitive heat stable antibiotic after a thorough debridement of the site. Primary wound closure was achieved in 99 patients and a split skin graft closure was done in one patient. Mean follow-up was 20 months (12 to 30).Aims

Excision of chronic osteomyelitic bone creates a dead space which must be managed to avoid early recurrence of infection. Systemic antibiotics cannot penetrate this space in high concentrations, so local treatment has become an attractive adjunct to surgery. The aim of this study was to present the mid- to long-term results of local treatment with gentamicin in a bioabsorbable ceramic carrier. A prospective series of 100 patients with Cierny-Mader Types III and IV chronic ostemyelitis, affecting 105 bones, were treated with a single-stage procedure including debridement, deep tissue sampling, local and systemic antibiotics, stabilization, and immediate skin closure. Chronic osteomyelitis was confirmed using strict diagnostic criteria. The mean follow-up was 6.05 years (4.2 to 8.4).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. We conducted a retrospective analysis of prospectively collected data of all patients with infected Charcot foot deformity who underwent two-stage reconstruction with internal fixation between July 2011 and November 2019, with a minimum of 12 months’ follow-up.Aims

We report the long-term outcomes of the UK Heel Fracture Trial (HeFT), a pragmatic, multicentre, two-arm, assessor-blinded, randomized controlled trial. HeFT recruited 151 patients aged over 16 years with closed displaced, intra-articular fractures of the calcaneus. Patients with significant deformity causing fibular impingement, peripheral vascular disease, or other significant limb injuries were excluded. Participants were randomly allocated to open reduction and internal fixation (ORIF) or nonoperative treatment. We report Kerr-Atkins scores, self-reported difficulty walking and fitting shoes, and additional surgical procedures at 36, 48, and 60 months.Aims

No randomized comparative study has compared the extensile lateral approach (ELA) and sinus tarsi approach (STA) for Sanders type 2 calcaneal fractures. This randomized comparative study was conducted to confirm whether the STA was prone to fewer wound complications than the ELA. Between August 2013 and August 2018, 64 patients with Sanders type 2 calcaneus fractures were randomly assigned to receive surgical treatment by the ELA (32 patients) and STA (32 patients). The primary outcome was development of wound complications. The secondary outcomes were postoperative complications, pain scored of a visual analogue scale (VAS), American Orthopaedic Foot and Ankle Society (AOFAS) score, 36-item Short Form health survey, operative duration, subtalar joint range of motion (ROM), Böhler’s angle and calcaneal width, and posterior facet reduction.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

The aim of this study was to investigate whether intraoperative 3D fluoroscopic imaging outperforms dorsal tangential views in the detection of dorsal cortex screw penetration after volar plating of an intra-articular distal radial fracture, as identified on postoperative CT imaging. A total of 165 prospectively enrolled patients who underwent volar plating for an intra-articular distal radial fracture were retrospectively evaluated to study three intraoperative imaging protocols: 1) standard 2D fluoroscopic imaging with anteroposterior (AP) and elevated lateral images (n = 55); 2) 2D fluoroscopic imaging with AP, lateral, and dorsal tangential views images (n = 50); and 3) 3D fluoroscopy (n = 60). Multiplanar reconstructions of postoperative CT scans served as the reference standard.Aims

Elective surgery has been severely curtailed as a result of the COVID-19 pandemic. There is little evidence to guide surgeons in assessing what processes should be put in place to restart elective surgery safely in a time of endemic COVID-19 in the community.

All patients were screened on admission and 100% of patients have been followed-up after discharge to assess outcome.Aims
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
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

This paper documents the epidemiology of adults (aged more than 18 years) with a calcaneal fracture who have been admitted to hospital in England since 2000. Secondary aims were to document whether publication of the United Kingdom Heel Fracture Trial (UK HeFT) influenced the proportion of patients admitted to hospital with a calcaneal fracture who underwent surgical treatment, and to determine whether there has been any recent change in the surgical technique used for these injuries. In England, the Hospital Episode Statistics (HES) data are recorded annually. Between 2000/01 and 2016/17, the number of adults admitted to an English NHS hospital with a calcaneal fracture and whether they underwent surgical treatment was determined.Aims

The traditional transosseus flexor hallucis longus (FHL) tendon
transfer for patients with Achilles tendinopathy requires two incisions
to harvest a long tendon graft. The use of a bio-tenodesis screw
enables a short graft to be used and is less invasive, but lacks
supporting evidence about its biomechanical behaviour. We aimed,
in this study, to compare the strength of the traditional transosseus
tendon-to-tendon fixation with tendon-to-bone fixation using a tenodesis
screw, in cyclical loading and ultimate load testing. Tendon grafts were undertaken in 24 paired lower-leg specimens
and randomly assigned in two groups using fixation with a transosseus
suture (suture group) or a tenodesis screw (screw group). The biomechanical
behaviour was evaluated using cyclical and ultimate loading tests.

were to answer the following questions: 1) Which of the 11 parameters
have the best inter- and intraobserver reliability in a standardized
radiological setting? 2) Are pre- and postoperative assessments
equally reliable? 3) What are the identifiable sources of variation? Measurements of the 11 parameters were recorded on anteroposterior
and lateral weight-bearing radiographs of 38 feet before and after
surgery for flatfoot, by three observers with different experience
in foot surgery (A, ten years; B, three years; C, third-year orthopaedic

The aim of this study was to present a series of patients with
aseptic failure of a total ankle arthroplasty (TAA) who were treated
with fusion of the hindfoot using a nail. A total of 23 TAAs, in 22 patients, were revised for aseptic
loosening and balloon osteolysis to a hindfoot fusion by a single
surgeon (NH) between January 2012 and August 2014. The procedure
was carried out without bone graft using the Phoenix, Biomet Hindfoot
Arthrodesis Nail. Preoperative investigations included full blood
count, CRP and ESR, and radiological investigations including plain
radiographs and CT scans. Postoperative plain radiographs were assessed
for fusion. When there was any doubt, CT scans were performed.Aims
Patients and 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

Inflammation of the retrocalcaneal bursa (RB) is a common clinical problem, particularly in professional athletes. RB inflammation is often treated with corticosteroid injections however a number of reports suggest an increased risk of Achilles tendon (AT) rupture. The aim of this cadaveric study was to describe the anatomical connections of the RB and to investigate whether it is possible for fluid to move from the RB into AT tissue. A total of 20 fresh-frozen AT specimens were used. In ten specimens, ink was injected into the RB. The remaining ten specimens were split into two groups to be injected with radiological contrast medium into the RB either with or without ultrasonography guidance (USG).Objectives

total knee arthroplasties (TKAs). A total of 60 TKAs (30 kinematically and 30 mechanically aligned)
were performed in 60 patients with varus osteoarthritis of the knee
using a navigation system. The angles of orientation of the joint
line in relation to the floor, the conventional and true mechanical
axis (tMA) (the line from the centre of the hip to the lowest point
of the calcaneus) were compared, one year post-operatively, on single-leg
and double-leg standing long leg radiographs between the groups.
The range of movement and 2011 Knee Society Scores were also compared
between the groups at that time.Aims

The purposes of this study were to clarify first, the incidence
of peroneal tendon dislocation in patients with a fracture of the
talus and second the factors associated with peroneal tendon dislocation. We retrospectively examined 30 patients (30 ankles) with a mean
age of 37.5 years, who had undergone internal fixation for a fracture
of the talus. Independent examiners assessed for peroneal tendon
dislocation using the pre-operative CT images. The medical records
were also reviewed for the presence of peroneal tendon dislocation.
The associations between the presence of dislocation with the patient
characteristics or radiological findings, including age, mechanism
of injury, severity of fracture, and fleck sign, were assessed using Fisher’s
exact tests.Aims

with OFD, OFD-like adamantinoma and adamantinoma between 1973 and
2012 was undertaken. Complete data were available for 73 patients
(42 with OFD; ten with an OFD-like adamantinoma and 21 with an adamantinoma).
The mean follow-up was 10.3 years (3 to 25) for OFD, 9.2 years (3.0

Aims. 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. Patients and Methods. 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

In recent years, the plantaris tendon has been
implicated in the development of chronic painful mid-portion Achilles tendinopathy.
In some cases, a thickened plantaris tendon is closely associated
with the Achilles tendon, and surgical excision of the plantaris
tendon has been reported to be curative in patients who have not
derived benefit following conservative treatment and surgical interventions. The aim of this review is to outline the basic aspects of, and
the recent research findings, related to the plantaris tendon, covering

Chronic osteomyelitis may recur if dead space management, after
excision of infected bone, is inadequate. This study describes the
results of a strategy for the management of deep bone infection
and evaluates a new antibiotic-loaded biocomposite in the eradication

in 105 bones. Osteomyelitis followed injury or surgery in 81 patients.
Nine had concomitant septic arthritis. 80 patients had comorbidities
(Cierny-Mader (C-M) Class B hosts). Ten had infected nonunions. All patients were treated by a multidisciplinary team with a

Although infrequent, a fracture of the cuboid can lead to significant
disruption of the integrity of the midfoot and its function. The
purpose of this study was to classify the pattern of fractures of
the cuboid, relate them to the mechanism of injury and suggest methods
of managing them. We performed a retrospective review of patients with radiologically
reported cuboid fractures. Fractures were grouped according to commonly

The accurate assessment of skeletal maturity
is essential in the management of orthopaedic conditions in the growing
child. In order to identify the time of peak height velocity (PHV)
in adolescents, two systems for assessing skeletal maturity have
been described recently; the calcaneal apophyseal ossification method
and the Sanders hand scores. The purpose of this study was to compare these methods in assessing
skeletal maturity relative to PHV. We studied the radiographs of
a historical group of 94 healthy children (49 females and 45 males),
who had been followed longitudinally between the ages of three and
18 years with serial radiographs and physical examination. Radiographs
of the foot and hand were undertaken in these children at least
annually between the ages of ten and 15 years. We reviewed 738 radiographs
of the foot and 694 radiographs of the hand. PHV was calculated
from measurements of height taken at the time of the radiographs. Prior to PHV we observed four of six stages of calcaneal apophyseal
ossification and two of eight Sanders stages. Calcaneal stage 3
and Sanders stage 2 was seen to occur about 0.9Â years before PHV,
while calcaneal stage 4 and Sanders stage 3 occurred approximately
0.5 years after PHV. The stages of the calcaneal and Sanders systems can be used in
combination, offering better assessment of skeletal maturity with
respect to PHV than either system alone. Cite this article:
Recently, several high impact randomised controlled
trials have been published suggesting no greater benefit from orthopaedic
surgery over conservative treatment, or limited surgical intervention.
These studies can have profound effects on clinical practice, leading
to the abandonment of previously widely-used operations. How do surgeons who believe these operations are beneficial over
conservative treatment rationalise these findings, and justify their
use with hospital administrators and health care funders who require
evidence for the value and efficacy of surgical treatment? Cite this article:
Ankle replacements have improved significantly since the first reported attempt at resurfacing of the talar dome in 1962. We are now at a stage where ankle replacement offers a viable option in the treatment of end-stage ankle arthritis. As the procedure becomes more successful, it is important to reflect and review the current surgical outcomes. This allows us to guide our patients in the treatment of end-stage ankle arthritis. What is the better surgical treatment – arthrodesis or replacement?
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:

We present a review of litigation claims relating
to foot and ankle surgery in the NHS in England during the 17-year period
between 1995 and 2012. A freedom of information request was made to obtain data from
the NHS litigation authority (NHSLA) relating to orthopaedic claims,
and the foot and ankle claims were reviewed. During this period of time, a total of 10 273 orthopaedic claims
were made, of which 1294 (12.6%) were related to the foot and ankle.
1036 were closed, which comprised of 1104 specific complaints. Analysis
was performed using the complaints as the denominator. The cost
of settling these claims was more than ÂŁ36 million. There were 372 complaints (33.7%) involving the ankle, of which
273 (73.4%) were related to trauma. Conditions affecting the first
ray accounted for 236 (21.4%), of which 232 (98.3%) concerned elective
practice. Overall, claims due to diagnostic errors accounted for
210 (19.0%) complaints, 208 (18.8%) from alleged incompetent surgery
and 149 (13.5%) from alleged mismanagement. Our findings show that the incorrect, delayed or missed diagnosis
of conditions affecting the foot and ankle is a key area for improvement,
especially in trauma practice. 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:
We report our experience using a biodegradable
calcium sulphate antibiotic carrier containing tobramycin in the surgical
management of patients with chronic osteomyelitis. The patients
were reviewed to determine the rate of recurrent infection, the
filling of bony defects, and any problems with wound healing. A
total of 193 patients (195 cases) with a mean age of 46.1 years
(16.1 to 82.0) underwent surgery. According to the Cierny–Mader
classification of osteomyelitis there were 12 type I, 1 type II,
144 type III and 38 type IV cases. The mean follow-up was 3.7 years (1.3
to 7.1) with recurrent infection occurring in 18Â cases (9.2%) at
a mean of 10.3 months post-operatively (1 to 25.0). After further
treatment the infection resolved in 191 cases (97.9%). Prolonged
wound ooze (longer than two weeks post-operatively) occurred in
30 cases (15.4%) in which there were no recurrent infection. Radiographic
assessment at final follow-up showed no filling of the defect with
bone in 67 (36.6%), partial filling in 108 (59.0%) and complete filling
in eight (4.4%). A fracture occurred in nine (4.6%) of the treated
osteomyelitic segments at a mean of 1.9 years (0.4 to 4.9) after
operation. We conclude that Osteoset T is helpful in the management of patients
with chronic osteomyelitis, but the filling of the defect in bone
is variable. Prolonged wound ooze is usually self-limiting and not
associated with recurrent infection. Cite this article:
Lengthening of the conjoined tendon of the gastrocnemius
aponeurosis and soleus fascia is frequently used in the treatment
of equinus deformities in children and adults. The Vulpius procedure
as described in most orthopaedic texts is a division of the conjoined
tendon in the shape of an inverted V. However, transverse division
was also described by Vulpius and Stoffel, and has been reported
in some clinical studies. We studied the anatomy and biomechanics of transverse division
of the conjoined tendon in 12 human cadavers (24 legs). Transverse
division of the conjoined tendon resulted in predictable, controlled
lengthening of the gastrocsoleus muscle-tendon unit. The lengthening
achieved was dependent both on the level of the cut in the conjoined
tendon and division of the midline raphé. Division at a proximal
level resulted in a mean lengthening of 15.2 mm ( Cite this article:
Fractures in patients aged ≥ 65 years constitute
an increasing burden on health and social care and are associated with
a high morbidity and mortality. There is little accurate information
about the epidemiology of fractures in the elderly. We have analysed
prospectively collected data on 4786 in- and out-patients who presented
with a fracture over two one-year periods. Analysis shows that there
are six patterns of the incidence of fractures in patients aged ≥ 65
years. In males six types of fracture increase in incidence after
the age of 65 years and 11 types increase in females aged over 65
years. Five types of fracture decrease in incidence after the age
of 65 years. Multiple fractures increase in incidence in both males
and females aged ≥ 65 years, as do fractures related to falls. Analysis of the incidence of fractures, together with life expectancy,
shows that the probability of males and females aged ≥ 65 years
having a fracture during the rest of their life is 18.5% and 52.0%,
respectively. The equivalent figures for males and females aged ≥ 80
years are 13.3% and 34.8%, respectively. Cite this article:

treatment time and the occurrence of failure, defined as two slippages
or a treatment time above eight weeks. A total of 26 children (33 feet) were entered into the trial.
The above-knee group comprised 17 feet in 13 children (ten boys
and three girls, median age 13 days (1 to 40)) and the below-knee
group comprised 16 feet in 13 children (ten boys and three girls,
median age 13 days (5 to 20)). Because of six failures (37.5%) in
the below-knee group, the trial was stopped early for ethical reasons.
The rate of failure was significantly higher in the below-knee group
(p = 0.039). The median treatment times of six weeks in the below-knee
and four weeks in the above-knee group differed significantly (p
= 0.01). This study demonstrates that the use of a below-knee plaster
of Paris cast in conjunction with the Ponseti technique leads to
unacceptably high failure rates and significantly longer treatment
times. Therefore, this technique is not recommended. Cite this article:
In a retrospective study we compared 32 HINTEGRA
total ankle replacements (TARs) and 35Â Mobility TARs performed between
July 2005 and May 2010, with a minimum follow-up of two years. The
mean follow-up for the HINTEGRA group was 53 months (24 to 76) and
for the Mobility group was 34 months (24 to 45). All procedures
were performed by a single surgeon. There was no significant difference between the two groups with
regard to the mean AOFAS score, visual analogue score for pain or
range of movement of the ankle at the latest follow-up. Most radiological
measurements did not differ significantly between the two groups.
However, the most common grade of heterotopic ossification (HO)
was grade 3 in the HINTEGRA group (10 of 13 TARs, 76.9%) and grade
2 in the Mobility group (four of seven TARs, 57.1%) (p = 0.025).
Although HO was more frequent in the HINTEGRA group (40.6%) than
in the Mobility group (20.0%), this was not statistically significant
(p = 0.065).The difference in peri-operative complications between
the two groups was not significant, but intra-operative medial malleolar
fractures occurred in four (11.4%) in the Mobility group; four (12.5%)
in the HINTEGRA group and one TAR (2.9%) in the Mobility group failed
(p = 0.185). Cite this article:
We reviewed 59 bone graft substitutes marketed
by 17 companies currently available for implantation in the United Kingdom,
with the aim of assessing the peer-reviewed literature to facilitate
informed decision-making regarding their use in clinical practice.
After critical analysis of the literature, only 22 products (37%)
had any clinical data. Norian SRS (Synthes), Vitoss (Orthovita),
Cortoss (Orthovita) and Alpha-BSM (Etex) had Level I evidence. We question
the need for so many different products, especially with limited
published clinical evidence for their efficacy, and conclude that
there is a considerable need for further prospective randomised
trials to facilitate informed decision-making with regard to the
use of current and future bone graft substitutes in clinical practice. Cite this article:
We conducted a randomised controlled trial to
determine whether active intense pulsed light (IPL) is an effective treatment
for patients with chronic mid-body Achilles tendinopathy. A total
of 47 patients were randomly assigned to three weekly therapeutic
or placebo IPL treatments. The primary outcome measure was the Victorian
Institute of Sport Assessment – Achilles (VISA-A) score. Secondary
outcomes were a visual analogue scale for pain (VAS) and the Lower
Extremity Functional Scale (LEFS). Outcomes were recorded at baseline,
six weeks and 12 weeks following treatment. Ultrasound assessment
of the thickness of the tendon and neovascularisation were also
recorded before and after treatment. There was no significant difference between the groups for any
of the outcome scores or ultrasound measurements by 12 weeks, showing
no measurable benefit from treatment with IPL in patients with Achilles tendinopathy. 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 30Â 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:
The purpose of this study was to evaluate the
clinical results of a newly designed prosthesis to replace the body
of the talus in patients with aseptic necrosis. Between 1999 and
2006, 22 tali in 22 patients were replaced with a ceramic prosthesis.
A total of eight patients were treated with the first-generation
prosthesis, incorporating a peg to fix into the retained neck and
head of the talus, and the remaining 14 were treated with the second-generation prosthesis,
which does not have the peg. The clinical results were assessed
by the American Orthopaedic Foot and Ankle Society ankle/hindfoot
scale. The mean follow-up was 98 months (18 to 174). The clinical results
of the first-generation prostheses were excellent in three patients,
good in one, fair in three and poor in one. There were, however,
radiological signs of loosening, prompting a change in design. The
clinical results of the second-generation prostheses were excellent
in three patients, good in five, fair in four and poor in two, with
more favourable radiological appearances. Revision was required
using a total talar implant in four patients, two in each group. Although the second-generation prosthesis produced better results,
we cannot recommend the use of a talar body prosthesis. We now recommend
the use of a total talar implant in these patients.
We investigated 60 patients (89 feet) with a
mean age of 64 years (61 to 67) treated for congenital clubfoot deformity,
using standardised weight-bearing radiographs of both feet and ankles
together with a functional evaluation. Talocalcaneal and talonavicular
relationships were measured and the degree of osteo-arthritic change
in the ankle and talonavicular joints was assessed. The functional
results were evaluated using a modified Laaveg-Ponseti score. The
talocalcaneal (TC) angles in the clubfeet were significantly lower
in both anteroposterior (AP) and lateral projections than in the
unaffected feet (p <
0.001 for both views). There was significant
medial subluxation of the navicular in the clubfeet compared with
the unaffected feet (p <
0.001). Severe osteoarthritis in the
ankle joint was seen in seven feet (8%) and in the talonavicular
joint in 11 feet (12%). The functional result was excellent or good
(≥ 80 points) in 29 patients (48%), and fair or poor (<
80 points)
in 31Â patients (52%). Patients who had undergone few (0 to 1) surgical
procedures had better functional outcomes than those who had undergone
two or more procedures (p <
0.001). There was a significant correlation
between the functional result and the degree of medial subluxation
of the navicular (p <
0.001, r2 = 0.164), the talocalcaneal
angle on AP projection (p <
0.02, r2 = 0.025) and extent of osteoarthritis
in the ankle joint (p <
0.001). We conclude that poor functional outcome in patients with congenital
clubfoot occurs more frequently in those with medial displacement
of the navicular, osteoarthritis of the talonavicular and ankle
joints, and a low talocalcaneal angle on the AP projection, and
in patients who have undergone two or more surgical procedures. However,
the ankle joint in these patients appeared relatively resistant
to the development of osteoarthritis.
A delay in the diagnosis of paediatric acute
and subacute haematogenous osteomyelitis can lead to potentially devastating
morbidity. There are no definitive guidelines for diagnosis, and
recommendations in the literature are generally based on expert
opinions, case series and cohort studies. All articles in the English literature on paediatric osteomyelitis
were searched using MEDLINE, CINAHL, EMBASE, Google Scholar, the
Cochrane Library and reference lists. A total of 1854 papers were
identified, 132 of which were examined in detail. All aspects of
osteomyelitis were investigated in order to formulate recommendations. On admission 40% of children are afebrile. The tibia and femur
are the most commonly affected long bones. Clinical examination,
blood and radiological tests are only reliable for diagnosis in
combination. Most studies were retrospective and there is a need for large,
multicentre, randomised, controlled trials to define protocols for
diagnosis and treatment. Meanwhile, evidence-based algorithms are
suggested for accurate and early diagnosis and effective treatment.

The April 2012 Trauma Roundup360 looks at fibula-pro-tibia plating, galeazzi fractures, distal radial fractures in the over 65s, transverse sacral fractures, acute dislocation of the knee, posterior malleolar fractures, immobilising the broken scaphoid, the terrible triad, lower limb amputation after trauma, and whiplash injuries
The use of autograft bone is the best option
when undertaking a procedure that requires bone graft because it
is osteogenic, osteoconductive and osseo-inductive. Pain, morbidity
and complications associated with harvesting iliac or non-iliac
sites occur in between 6% and 30% of cases. An alternative source
of graft with possibly a lower morbidity is the intramedullary canal.
In this study, 28 patients undergoing 30 arthrodesis procedures
on the hindfoot had a mean of 48 cm. 3 . (43 to 50) of bone
harvested locally from the hindfoot or the tibial shaft by antegrade or
retrograde reaming. No patient sustained a fracture of the
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 28.7Â 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.
This is a prospective analysis on 30 physically
active individuals with a mean age of 48.9Â years (35 to 64) with chronic
insertional tendinopathy of the tendo Achillis. Using a transverse
incision, the tendon was debrided and an osteotomy of the posterosuperior
corner of the calcaneus was performed in all patients. At a minimum
post-operative follow-up of three years, the Victorian Institute
of Sports Assessment scale – Achilles tendon scores were significantly
improved compared to the baseline status. In two patients a superficial
infection of the wound developed which resolved on antibiotics.
There were no other wound complications, no nerve related complications,
and no secondary avulsions of the tendo Achillis. In all, 26 patients
had returned to their pre-injury level of activity and the remaining
four modified their sporting activity. At the last appointment,
the mean pain threshold and the mean post-operative tenderness were
also significantly improved from the baseline (p <
0.001). In patients
with insertional tendo Achillis a transverse incision allows a wide
exposure and adequate debridement of the tendo Achillis insertion,
less soft-tissue injury from aggressive retraction and a safe osteotomy

We undertook a prospective study to analyse the
outcome of 48 malunited pronation-external rotation fractures of the
ankle in 48 patients (25 females and 23 males) with a mean age of
45 years (21 to 69), treated by realignment osteotomies. The interval
between the injury and reconstruction was a mean of 20.2 months
(3 to 98). In all patients, valgus malalignment of the distal tibia and
malunion of the fibula were corrected. In some patients, additional
osteotomies were performed. Patients were reviewed regularly, and
the mean follow-up was 7.1 years (2 to 15). Good or excellent results were obtained in 42 patients (87.5%)
with the benefit being maintained over time. Congruent ankles without
a tilted talus (Takakura stage 0 and 1) were obtained in all but
five cases. One patient required total ankle replacement.
It has been suggested that a supramalleolar osteotomy can return the load distribution in the ankle joint to normal. However, due to the lack of biomechanical data, this supposition remains empirical. The purpose of this biomechanical study was to determine the effect of simulated supramalleolar varus and valgus alignment on the tibiotalar joint pressure, in order to investigate its relationship to the development of osteoarthritis. We also wished to establish the rationale behind corrective osteotomy of the distal tibia. We studied 17 cadaveric lower legs and quantified the changes in pressure and force transfer across the tibiotalar joint for various degrees of varus and valgus deformity in the supramalleolar area. We assumed that a supramalleolar osteotomy which created a varus deformity of the ankle would result in medial overload of the tibiotalar joint. Similarly, we thought that creating a supramalleolar valgus deformity would cause a shift in contact towards the lateral side of the tibiotalar joint. The opposite was observed. The restricting role of the fibula was revealed by carrying out an osteotomy directly above the syndesmosis. In end-stage ankle osteoarthritis with either a valgus or varus deformity, the role of the fibula should be appreciated and its effect addressed where appropriate.
Compartment syndrome of the foot is usually associated with trauma, and if untreated may result in deformity and loss of function. We report a case of spontaneous compartment syndrome of the foot presenting with severe unremitting pain. The diagnosis was supported by measurements of compartment pressures and the symptoms resolved after surgical decompression. Spontaneous compartment syndrome in the leg has been described in a small number of cases, but there has been no previous report involving the foot. We believe that this case highlights the importance of suspecting a spontaneous compartment syndrome of the foot if the appropriate symptoms are present but there is no clear cause. We also believe that compartment pressure measurement assists in the decision to undertake surgical decompression.
A high rate of complications is associated with open reduction and internal fixation of Sanders type 4 fractures of the
Survivors of infantile meningococcal septicaemia often develop progressive skeletal deformity as a result of physeal damage at many sites, particularly in the lower limb. Distal tibial physeal arrest typically occurs with sparing of the distal fibular physis leading to a rapidly progressive varus deformity. There have been reports of isolated cases of this deformity, but to our knowledge there have been no papers which specifically describe the development of the deformity and the options for treatment. Surgery to correct this deformity is complex because of the patient’s age, previous scarring and the multiplanar nature of the deformity. The surgical goal is to restore leg-length equality and the mechanical axis at the end of growth. Surgery should be planned and staged throughout growth in order to achieve the best functional results. We report our experience in six patients (seven ankles) with this deformity, who were managed by corrective osteotomy using a programmable circular fixator.
We compared the complications and outcome of tibial lengthening using the Ilizarov method with and without the use of a supplementary intramedullary nail. In a retrospective case-matched series assembled from 176 patients with tibial lengthening, we matched 52 patients (26 pairs, group A with nail and group B without) according to the following criteria in order of importance: 1) difference in amount of lengthening (± 2 cm); 2) percentage difference in lengthening (± 5%); 3) difference in patient’s age (± seven years); 4) aetiology of the shortening, and 5) level of difficulty in obtaining the correction. The outcome was evaluated using the external fixator index, the healing index and an outcome score according to the criteria of Paley. It was found that some complications were specific to group A or B respectively, but others were common to both groups. The outcome was generally better in lengthenings with a nail, although there was a higher incidence of rectifiable equinus deformity in these patients.
We report the clinical and radiological outcome of total ankle replacement performed in conjunction with hindfoot fusion or in isolation. Between May 2003 and June 2008, 60 ankles were treated with total ankle replacement with either subtalar or triple fusion, and the results were compared with a control group of 288 ankles treated with total ankle replacement alone. After the mean follow-up of 39.5 months (12 to 73), the ankles with hindfoot fusion showed significant improvement in the mean visual analogue score for pain (p <
0.001), the mean American Orthopaedic Foot and Ankle Society score (p <
0.001), and the mean of a modified version of this score (p <
0.001). The mean visual analogue pain score (p = 0.304) and mean modified American Orthopaedic Foot and Ankle Society score (p = 0.119) were not significantly different between the hindfoot fusion and the control groups. However, the hindfoot fusion group had a significantly lower mean range of movement (p = 0.009) and a higher rate of posterior focal osteolysis (p = 0.04). Both groups showed various complications (p = 0.131) and failure occurring at a similar rate (p = 0.685). Subtalar or triple fusion is feasible and has minimal adverse effects on ankles treated with total ankle replacement up to midterm follow-up. The clinical outcome of total ankle replacement when combined with hindfoot fusion is comparable to that of ankle replacement alone. Thus, hindfoot fusion should be performed in conjunction with total ankle replacement when indicated.
We present a retrospective review of 167 patients aged 18 years and under who were treated for chronic haematogenous osteomyelitis at our elective orthopaedic hospital in Malawi over a period of four years. The median age at presentation was eight years (1 to 18). There were 239 hospital admissions for treatment during the period of the study. In 117 patients one admission was necessary, in 35 two, and in 15 more than two. A surgical strategy of infection control followed by reconstruction and stabilisation was employed, based on the Beit CURE radiological classification of chronic haematogenous osteomyelitis as a guide to treatment. At a minimum follow-up of one year after the end of the study none of the patients had returned to our hospital with recurrent infection. A total of 350 operations were performed on the 167 patients. This represented 6.7% of all children’s operations performed in our hospital during this period. One operation only was required in 110 patients and none required more than three. Below-knee amputation was performed in two patients with chronic calcaneal osteomyelitis as the best surgical option for function. The most common organism cultured from operative specimens was
We describe five adolescent patients aged between 13 and 16 years with bipartite ossification of the posteromedial aspect of the talus. All presented without a history of trauma. All the ankles had a similar radiological appearance. Clinically, some restriction of movement was noted in three ankles and two subtalar joints, In addition, pain was noted over the posteromedial aspect of the ankle in three patients. In each patient the bipartite fragment was excised through a posteromedial approach to the ankle. Complete resolution was achieved at six months in three patients, with the remaining two describing exercise-induced symptoms. In one of these this precluded participation in sport. Despite numerous anatomical variations within the tarsus, a case series of a bipartite talus has not previously been reported. This anatomical variation should be recognised to avoid misinterpretation as post-traumatic or other pathological processes. In the presence of recalcitrant symptoms excision is an option, but this is not universally successful in abolishing symptoms.
Subtalar dislocation is a significant injury characterised by late complications, including subtalar arthritis. We describe a rare case of irreducible posterior subtalar dislocation due to incarceration of a fracture of the anterior process of the
A child with traumatic laceration of the tendo Achillis developed secondary infection after primary repair. This resulted in the loss of 5 cm of the distal part of the tendon and overlying soft tissue. The patient was treated with a free skin flap to cover the wound and to control the infection leaving reconstruction for a second-stage procedure. However, when he was assessed two years after the skin-flap, delayed reconstruction proved to be unnecessary since he had regained normal ankle function spontaneously and could demonstrate equal function in both tendons.
We carried out a retrospective review of 47 intra-articular fractures of the
The databases of the Picture Archiving and Communication Systems of two hospitals were searched and all children who had a lateral radiograph of the ankle during their attendance at the emergency department were identified. In 227 radiographs, Bohler’s and Gissane’s angles were measured on two separate occasions and by two separate authors to allow calculation of inter- and intra-observer variation. Intraclass correlation coefficients were used to assess the reliability of the measurements. For Bohler’s angle the overall inter-observer reliability, the intraclass correlation coefficient was 0.90 and the intra-observer reliability 0.95, giving excellent agreement. This reliability was maintained across the age groups. For Gissane’s angle, inter- and intra-observer reliability was only fair or poor across most age groups. Further analysis of the Bohler’s angle showed a significant variation in the mean angle with age. Contrary to published opinion, the angle is not uniformly lower than that of adults but varies with age, peaking towards the end of the first decade before attaining adult values. The age-related radiologic changes presented here may help in the interpretation of injuries to the hindfoot in children.
The treatment of infected exposed implants which have been used for internal fixation usually involves debridement and removal of the implant. This can result in an unstable fracture or spinal column. Muscle flaps may be used to salvage these implants since they provide soft-tissue cover and fresh vascularity. However, there have been few reports concerning their use and these have concentrated on the eradication of the infection and successful soft-tissue cover as the endpoint. There is no information on the factors which may influence the successful salvage of the implant using muscle flaps. We studied the results and factors affecting outcome in nine pedicled muscle flaps used in the treatment of exposed metal internal fixation with salvage of the implant as the primary endpoint. This was achieved in four cases. Factors predicting success were age <
30 years, the absence of comorbid conditions and a favourable microbiological profile. The growth of multiple organisms, a history of smoking and the presence of methicillin-resistant Staphylococcus aureus on wound cultures indicated a poor outcome. The use of antibiotic beads, vacuum-assisted closure and dressing, the surgical site, the type of flap performed and the time from primary surgery to flap cover were not predictive of outcome.
A total of 38 relapsed congenital clubfeet (16 stiff, 22 partially correctable) underwent revision of soft-tissue surgery, with or without a bony procedure, and transfer of the tendon of tibialis anterior at a mean age of 4.8 years (2.0 to 10.1). The tendon was transferred to the third cuneiform in five cases, to the base of the third metatarsal in ten and to the base of the fourth in 23. The patients were reviewed at a mean follow-up of 24.8 years (10.8 to 35.6). A total of 11 feet were regarded as failures (one a tendon failure, five with a subtalar fusion due to over-correction, and five with a triple arthrodesis due to under-correction or relapse). In the remaining feet the clinical outcome was excellent or good in 20 and fair or poor in seven. The mean Laaveg-Ponseti score was 81.6 of 100 points (52 to 92). Stiffness was mild in four feet and moderate or severe in 23. Comparison between the post-operative and follow-up radiographs showed statistically significant variations of the talo-first metatarsal angle towards abduction. Variations of the talocalcaneal angles and of the overlap ratio were not significant. Extensive surgery for relapsed clubfoot has a high rate of poor long-term results. The addition of transfer of the tendon of tibialis anterior can restore balance and may provide some improvement of forefoot adduction. However, it has a considerable complication rate, including failure of transfer, over-correction, and weakening of dorsiflexion. The procedure should be reserved for those limited cases in which muscle imbalance is a causative or contributing factor.
The use of ultrasound in the diagnosis and management of disorders of the tendo Achillis is discussed. Some of the pathological processes which occur in Achilles tendinopathy can be identified by ultrasound, which may also be used to direct local treatment.
We describe a 63-year-old man who had xanthomatosis of the right tendo Achillis. He had undergone excision of the left tendo Achillis 17 years earlier without reconstruction for the same condition. The neurological history and examination were normal. Blood investigations showed hypercholestrolaemia, for which he was being treated with statins. He was referred with pain in the right tendo Achillis and problems with footwear. He was treated by excision of the right tendo Achillis, the xanthomatous nodules and the involved skin, followed by reconstruction with a cadaver bone-tendon graft. At follow-up eight months postoperatively, the scar had healed well. He walked without pain and could wear any type of shoe. Plain radiographs showed that the bone graft had healed. The American Orthopaedic Foot and Ankle Society hindfoot score was 95/100. The patient’s subjective evaluation of the result was very good.
The results of further soft-tissue release of 79 feet in 60 children with recurrent idiopathic congenital talipes equinovarus were evaluated. The mean age of the children at the time of re-operation was 5.8 years (15 months to 14.5 years). Soft-tissue release was performed in all 79 feet and combined with distal calcaneal excision in 52 feet. The mean follow-up was 12 years (4 to 32). At the latest follow-up the result was excellent or good in 61 feet (77%) according to the Ghanem and Seringe scoring system. The results was considered as fair in 14 feet (18%), all of whom had functional problems and eight had anatomical abnormalities. Four feet (5%) were graded as poor on both functional and anatomical grounds. The results were independent of the age at which revision was undertaken.
We describe a retrospective review of the clinical and radiological parameters of 32 feet in 30 patients (10 men and 20 women) who underwent correction for malalignment of the hindfoot with a modified double arthrodesis through a medial approach. The mean follow-up was 21 months (13 to 37). Fusion was achieved in all feet at a mean of 13 weeks (6 to 30). Apart from the calcaneal pitch angle, all angular measurements improved significantly after surgery. Primary wound healing occurred without complications. The isolated medial approach to the subtalar and talonavicular joints allows good visualisation which facilitated the reduction and positioning of the joints. It was also associated with fewer problems with wound healing than the standard lateral approach.
We report a case in which Ilizarov distraction osteogenesis was used to lengthen the portion of
We present the results of ankle fusion using the Ilizarov technique for bone loss around the ankle in 20 patients. All except one had sustained post-traumatic bone loss. Infection was present in 17. The mean age was 33.1 years (7 to 71). The mean size of the defect was 3.98 cm (1.5 to 12) and associated limb shortening before the index procedure varied from 1 cm to 5 cm. The mean time in the external fixator was 335 days (42 to 870). Tibiotalar fusion was performed in 19 patients and tibiocalcaneal fusion in one. Associated problems included diabetes in one patient, pelvic and urethral injury in one, visual injury in one patient and ipsilateral tibial fracture in five. At the final mean follow-up of 51.55 months (24 to 121) fusion had been achieved in 19 of 20 patients. A total of 16 patients were able to return to work. The results were graded as good in 11 patients, fair in six and poor in three. The mean external fixation index was 8.8 days/mm (0 to 30). One patient with diabetes developed severe infection which required early removal of the fixator. Refractures occurred in three patients, two of which were at the site of fusion and one at a previous tibial shaft fracture site. Equinus deformity of the ankle fusion occurred after a further fracture in one patient. There were two patients with residual forefoot equinus, and one developed late valgus at the fusion site. Poor consolidation of the regenerated bone in two patients was treated by bone grafting in one and by bone and fibular strut grafting in the other. Residual soft-tissue infection was still present in two patients.
Conventional non-steroidal anti-inflammatory drugs (NSAIDs) and newer specific cyclo-oxygenase-2 (cox-2) inhibitors are commonly used in musculoskeletal trauma and orthopaedic surgery to reduce the inflammatory response and pain. These drugs have been reported to impair bone metabolism. In reconstruction of the anterior cruciate ligament the hamstring tendons are mainly used as the graft of choice, and a prerequisite for good results is healing of the tendons in the bone tunnel. Many of these patients are routinely given NSAIDs or cox-2 inhibitors, although no studies have elucidated the effects of these drugs on tendon healing in the bone tunnel. In our study 60 female Wistar rats were randomly allocated into three groups of 20. One received parecoxib, one indometacin and one acted as a control. In all the rats the tendo-Achillis was released proximally from the calf muscles. It was then pulled through a drill hole in the distal tibia and sutured anteriorly. The rats were given parecoxib, indometacin or saline intraperitoneally twice daily for seven days. After 14 days the tendon/bone-tunnel interface was subjected to mechanical testing. Significantly lower maximum pull-out strength (p <
0.001), energy absorption (p <
0.001) and stiffness (p = 0.035) were found in rats given parecoxib and indometacin compared with the control group, most pronounced with parecoxib.
The extended lateral L-shaped approach for the treatment of displaced intra-articular fractures of the
We describe the surgical technique and results of arthroscopic subtalar release in 17 patients (17 feet) with painful subtalar stiffness following an intra-articular calcaneal fracture of Sanders’ type II or III. The mean duration from injury to arthroscopic release was 11.3 months (6.4 to 36) and the mean follow-up after release was 16.8 months (12 to 25). The patient was positioned laterally and three arthroscopic portals were placed anterolaterally, centrally and posterolaterally. The sinus tarsi and lateral gutter were debrided of fibrous tissue and the posterior talocalcaneal facet was released. In all, six patients were very satisfied, eight were satisfied and three were dissatisfied with their results. The mean American Orthopaedic Foot and Ankle Society ankle-hindfoot score improved from a mean of 49.4 points (35 to 66) pre-operatively to a mean of 79.6 points (51 to 95). All patients reported improvement in movement of the subtalar joint. No complications occurred following operation, but two patients subsequently required subtalar arthrodesis for continuing pain. In the majority of patients a functional improvement in hindfoot function was obtained following arthroscopic release of the subtalar joint for stiffness and pain secondary to Sanders type II and III fractures of the
Hallux rigidus was first described in 1887. Many aetiological factors have been postulated, but none has been supported by scientific evidence. We have examined the static and dynamic imbalances in the first metatarsophalangeal joint which we postulated could be the cause of this condition. We performed a finite-element analysis study on a male subject and calculated a mathematical model of the joint when subjected to both normal and abnormal physiological loads. The results gave statistically significant evidence for an increase in tension of the plantar fascia as the cause of abnormal stress on the articular cartilage rather than mismatch of the articular surfaces or subclinical muscle contractures. Our study indicated a clinical potential cause of hallux rigidus and challenged the many aetiological theories. It could influence the choice of surgical procedure for the treatment of early grades of hallux rigidus.
We studied 11 patients with checkrein deformities of the hallux who underwent surgical treatment. Six had lengthening of the flexor hallucis longus tendon by Z-plasty in the midfoot, and five underwent release of adhesions and lengthening of the tendon by Z-plasty at the musculotendinous junction at the fracture site. All six patients who underwent Z-plasty at the midfoot showed complete correction of the deformity without recurrence. Of the five who had release of adhesions and Z-plasty of the tendon at the fracture site, two showed partial and one showed complete recurrence.
Compartment syndrome of the foot requires urgent surgical treatment. Currently, there is still no agreement on the number and location of the myofascial compartments of the foot. The aim of this cadaver study was to provide an anatomical basis for surgical decompression in the event of compartment syndrome. We found that there were three tough vertical fascial septae that extended from the hindfoot to the midfoot on the plantar aspect of the foot. These septae separated the posterior half of the foot into three compartments. The medial compartment containing the abductor hallucis was surrounded medially by skin and subcutaneous fat and laterally by the medial septum. The intermediate compartment, containing the flexor digitorum brevis and the quadratus plantae more deeply, was surrounded by the medial septum medially, the intermediate septum laterally and the main plantar aponeurosis on its plantar aspect. The lateral compartment containing the abductor digiti minimi was surrounded medially by the intermediate septum, laterally by the lateral septum and on its plantar aspect by the lateral band of the main plantar aponeurosis. No distinct myofascial compartments exist in the forefoot. Based on our findings, in theory, fasciotomy of the hindfoot compartments through a modified medial incision would be sufficient to decompress the foot.
Salvage of a failed total ankle replacement is technically challenging and although a revision procedure may be desirable, a large amount of bone loss or infection may preclude this. Arthrodesis can be difficult to achieve and is usually associated with considerable shortening of the limb. We describe a technique for restoring talar height using an allograft from the femoral head compressed by an intramedullary nail. Three patients with aseptic loosening were treated successfully by this method with excellent symptomatic relief at a mean follow-up of 32 months (13 to 50).
This study was undertaken to evaluate the safety and efficacy of retrievable inferior vena cava filters in high-risk orthopaedic patients. A total of 58 patients had a retrievable inferior vena cava filter placed as an adjunct to chemical and mechanical prophylaxis, most commonly for a history of previous deep-vein thrombosis or pulmonary embolism, polytrauma, or expected prolonged immobilisation. In total 56 patients (96.6%) had an uncomplicated post-operative course. Two patients (3.4%) died in the peri-operative period for unrelated reasons. Of the 56 surviving patients, 50 (89%) were available for follow-up. A total of 32 filters (64%) were removed without complication at a mean of 37.8 days (4 to 238) after placement. There were four filters (8%) which were retained because of thrombosis at the filter site, and four (8%) were retained because of incorporation of the filter into the wall of the inferior vena cava. In ten cases (20%) the retrievable filter was left in place to continue as primary prophylaxis. No patient had post-removal thromboembolic complications. A retrievable inferior vena cava filter, as an adjunct to chemical and mechanical prophylaxis, was a safe and effective means of reducing the acute risk of pulmonary embolism in this high-risk group of patients. Although most filters were removed without complications, thereby avoiding the long-term complications that have plagued permanent indwelling filters, a relatively high percentage of filters had to be left
Thrombin has many biological properties similar to those of growth factors. In a previous study, we showed that thrombin improves healing of the rat tendo Achillis. Low molecular weight heparin (LMWH) inhibits the activity and the generation of thrombin. We therefore considered that LMWH at a thromboprophylactic dose might inhibit tendon repair. Transection of the tendo Achillis was carried out in 86 rats and the healing tested mechanically. Low molecular weight heparin (dalateparin) was either injected a few minutes before the operation and then given continuously with an osmotic mini pump for seven days, or given as one injection before the operation. In another experiment ,we gave LMWH or a placebo by injection twice daily. The anti-factor Xa activity was analysed. Continuous treatment with LMWH impaired tendon healing. After seven days, this treatment caused a 33% reduction in force at failure, a 20% reduction in stiffness and a 67% reduction in energy uptake. However, if injected twice daily, LMWH had no effect on tendon healing. Anti-factor Xa activity was increased by LMWH treatment, but was normal between intermittent injections. Low molecular weight heparin delays tendon repair if given continuously, but not if injected intermittently, probably because the anti-factor Xa activity between injections returns to normal, allowing sufficient thrombin stimulation for repair. These findings indicate the need for caution in the assessment of long-acting thrombin and factor Xa inhibitors.
We have compared the outcomes of the use of external fixation devices for spanning or sparing the ankle joint in the treatment of fractures of the tibial plafond, focusing on the complications and the rates of healing. We have devised a scoring system for the quality of reporting of clinical outcomes, to determine the reliability of the results. We conducted a search of publications in English between 1990 and 2006 using the Pubmed search engine. The key words used were pilon, pylon, plafond fractures, external fixation. A total of 15 articles, which included 465 fractures, were eligible for final evaluation. There were no statistically significant differences between spanning and sparing fixation systems regarding the rates of infection, nonunion, and the time to union. Patients treated with spanning frames had significantly greater incidence of malunion compared with patients treated with sparing frames. In both groups, the outcome reporting score was very low; 60% of reports involving infection, nonunion or malunion scored 0 points.
Rocker bottom deformity may occur during the conservative treatment of idiopathic congenital clubfoot. Between 1975 and 1996, we treated 715 patients (1120 clubfeet) conservatively. A total of 23 patients (36 feet; 3.2%) developed a rocker bottom deformity. It is these patients that we have studied. The pathoanatomy of the rocker bottom deformity is characterised by a plantar convexity appearing between three and six months of age with the hindfoot equinus position remaining constant. The convexity initially involves the medial column, radiologically identified by the talo-first metatarsal angle and secondly by the lateral column, revealed radiologically as the calcaneo-fifth metatarsal angle. The apex of the deformity is usually at the midtrasal with a dorsal calcaneocuboid subluxation. Ideal management of clubfoot deformity should avoid this complication, with adequate manipulation and splinting and early Achilles’ percutaneous tenotomy if plantar convexity occurs. Adequate soft-tissue release provides satisfactory correction for rocker bottom deformity. However, this deformity requires more extensive and complex procedures than the standard surgical treatment of clubfoot. The need for lateral radiographs to ensure that the rocker bottom deformity is recognised early, is demonstrated.
We undertook a trial on 60 patients with AO 31A2 fractures of the hip who were randomised after stabilisation of the fracture into two equal groups, one of which received post-operative treatment using a non-invasive interactive neurostimulation device and the other with a sham device. All other aspects of their rehabilitation were the same. The treatment was continued for ten days after operation. Outcome measurements included the use of a visual analogue scale for pain, the brief pain inventory and Ketorolac for post-operative control of pain, and an overall assessment of outcome by the surgeon. There were significantly better results for the patients receiving treatment by active electrical stimulation (repeated measures analysis of variance, p <
0.001). The findings of this pilot trial justify a larger study to determine if these results are more generally applicable.
