We prospectively assessed the diagnostic accuracy
of the gravity stress test and clinical findings to evaluate the stability
of the ankle mortise in patients with supination–external rotation-type
fractures of the lateral malleolus without widening of the medial
clear space. The cohort included 79 patients with a mean age of
44 years (16 to 82). Two surgeons assessed medial tenderness, swelling
and ecchymosis and performed the external rotation (ER) stress test
(a reference standard). A diagnostic radiographer performed the
gravity stress test. For the gravity stress test, the positive likelihood ratio (LR)
was 5.80 with a 95% confidence interval (CI) of 2.75 to 12.27, and
the negative LR was 0.15 (95% CI 0.07 to 0.35), suggesting a moderate
change from the pre-test probability. Medial tenderness, both alone
and in combination with
The aim of this study was to compare the functional and radiological outcomes and the complication rate after nail and plate fixation of unstable fractures of the ankle in elderly patients. In this multicentre study, 120 patients aged ≥ 60 years with an acute unstable AO/OTA type 44-B fracture of the ankle were randomized to fixation with either a nail or a plate and followed for 24 months after surgery. The primary outcome measure was the American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot score. Secondary outcome measures were the Manchester-Oxford Foot Questionnaire, the Olerud and Molander Ankle score, the EuroQol five-dimension questionnaire, a visual analogue score for pain, complications, the quality of reduction of the fracture, nonunion, and the development of osteoarthritis.Aims
Methods
Proper preoperative planning benefits fracture reduction, fixation, and stability in tibial plateau fracture surgery. We developed and clinically implemented a novel workflow for 3D surgical planning including patient-specific drilling guides in tibial plateau fracture surgery. A prospective feasibility study was performed in which consecutive tibial plateau fracture patients were treated with 3D surgical planning, including patient-specific drilling guides applied to standard off-the-shelf plates. A postoperative CT scan was obtained to assess whether the screw directions, screw lengths, and plate position were performed according the preoperative planning. Quality of the fracture reduction was assessed by measuring residual intra-articular incongruence (maximum gap and step-off) and compared to a historical matched control group.Aims
Methods
Pneumatic tourniquets are often used during the surgical treatment of unstable traumatic ankle fractures. The aim of this study was to assess the risk of reoperation after open reduction and internal fixation of ankle fractures with and without the use of pneumatic tourniquets. This was a population-based cohort study using data from the Danish Fracture Database with a follow-up period of 24 months. Data were linked to the Danish National Patient Registry to ensure complete information regarding reoperations due to complications, which were divided into major and minor. The relative risk of reoperations for the tourniquet group compared with the non-tourniquet group was estimated using Cox proportional hazards modelling.Aims
Methods
The aims of this study were to assess the pre- and postoperative incidence of deep vein thrombosis (DVT) using routine duplex Doppler ultrasound (DUS), to assess the incidence of pulmonary embolism (PE) using CT angiography, and to identify the factors that predict postoperative DVT in patients with a pelvic and/or acetabular fracture. All patients treated surgically for a pelvic and/or acetabular fracture between October 2016 and January 2020 were enrolled into this prospective single-centre study. The demographic, medical, and surgical details of the patients were recorded. DVT screening of the lower limbs was routinely performed using DUS before and at six to ten days after surgery. CT angiography was used in patients who were suspected of having PE. Age-adjusted univariate and stepwise multiple logistic regression analysis were used to determine the association between explanatory variables and postoperative DVT.Aims
Methods
Deep surgical site infection (SSI) is common after lower limb fracture. We compared the diagnosis of deep SSI using alternative methods of data collection and examined the agreement of clinical photography and in-person clinical assessment by the Centers for Disease Control and Prevention (CDC) criteria after lower limb fracture surgery. Data from two large, UK-based multicentre randomized controlled major trauma trials investigating SSI and wound healing after surgical repair of open lower limb fractures that could not be primarily closed (UK WOLLF), and surgical incisions for fractures that were primarily closed (UK WHiST), were examined. Trial interventions were standard wound care management and negative pressure wound therapy after initial surgical debridement. Wound outcomes were collected from 30 days to six weeks. We compared the level of agreement between wound photography and clinical assessment of CDC-defined SSI. We are also assessed the level of agreement between blinded independent assessors of the photographs.Aims
Methods
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
Methods
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
Methods
To identify the prevalence of neuropathic pain after lower limb fracture surgery, assess associations with pain severity, quality of life and disability, and determine baseline predictors of chronic neuropathic pain at three and at six months post-injury. Secondary analysis of a UK multicentre randomized controlled trial (Wound Healing in Surgery for Trauma; WHiST) dataset including adults aged 16 years or over following surgery for lower limb major trauma. The trial recruited 1,547 participants from 24 trauma centres. Neuropathic pain was measured at three and six months using the Doleur Neuropathique Questionnaire (DN4); 701 participants provided a DN4 score at three months and 781 at six months. Overall, 933 participants provided DN4 for at least one time point. Physical disability (Disability Rating Index (DRI) 0 to 100) and health-related quality-of-life (EuroQol five-dimension five-level; EQ-5D-5L) were measured. Candidate predictors of neuropathic pain included sex, age, BMI, injury mechanism, concurrent injury, diabetes, smoking, alcohol, analgaesia use pre-injury, index surgery location, fixation type, Injury Severity Score, open injury, and wound care.Aims
Methods
To clarify the effectiveness of the induced membrane technique (IMT) using beta-tricalcium phosphate (β-TCP) for reconstruction of segmental bone defects by evaluating clinical and radiological outcomes, and the effect of defect size and operated site on surgical outcomes. A review of the medical records was conducted of consecutive 35 lower limbs (30 males and five females; median age 46 years (interquartile range (IQR) 40 to 61)) treated with IMT using β-TCP between 2014 and 2018. Lower Extremity Functional Score (LEFS) was examined preoperatively and at final follow-up to clarify patient-centered outcomes. Bone healing was assessed radiologically, and time from the second stage to bone healing was also evaluated. Patients were divided into ≥ 50 mm and < 50 mm defect groups and into femoral reconstruction, tibial reconstruction, and ankle arthrodesis groups.Aims
Methods
The imaging techniques available to aid the diagnosis of ruptures of tendo Achillis, the rotator cuff and the tendon of tibialis posterior in rheumatoid patients are well described. However, ruptures of tendon or muscle at other sites are uncommon and may be overlooked. Diagnosis is often made by localised tenderness,
We describe six patients aged from 10 to 15 years who, after injury to the distal tibial physis, presented with the following clinical findings: 1) severe pain and
The aim of this study was to evaluate the diagnostic value of preoperative serum CRP, white blood cell count (WBC), percentage of neutrophils (%N), and neutrophil to lymphocyte ratio (NLR) when using the fracture-related infection (FRI) consensus definition. A cohort of 106 patients having surgery for suspected septic nonunion after failed fracture fixation were studied. Blood samples were collected preoperatively, and the concentration of serum CRP, WBC, and differential cell count were analyzed. The areas under the curve (AUCs) of diagnostic tests were compared using the z-test. Regression trees were constructed and internally cross-validated to derive a simple diagnostic decision tree.Aims
Methods
The aim of this study was to report the outcome following primary
fixation or a staged protocol for type C fractures of the tibial
plafond. We studied all patients who sustained a complex intra-articular
fracture (AO type C) of the distal tibia over an 11-year period.
The primary short-term outcome was infection. The primary long-term
outcome was the Foot and Ankle Outcome Score (FAOS).Aims

This study assessed the association of classes of body mass index
in kg/m2 (classified as normal weight 18.5 kg/m2 to
24.9 kg/m2, overweight 25.0 kg/m2 to 29.9
kg/m2, and obese ≥ 30.0 kg/m2) with short-term
complications and functional outcomes three to six years post-operatively
for closed ankle fractures. We performed a historical cohort study with chart review of 1011
patients who were treated for ankle fractures by open reduction
and internal fixation in two hospitals, with a follow-up postal
survey of 959 of the patients using three functional outcome scores.Aims
Patients and Methods
External fixators are the traditional fixation method of choice for contaminated open fractures. However, patient acceptance is low due to the high profile and therefore physical burden of the constructs. An externalised locking compression plate is a low profile alternative. However, the biomechanical differences have not been assessed. The objective of this study was to evaluate the axial and torsional stiffness of the externalised titanium locking compression plate (ET-LCP), the externalised stainless steel locking compression plate (ESS-LCP) and the unilateral external fixator (UEF). A fracture gap model was created to simulate comminuted mid-shaft tibia fractures using synthetic composite bones. Fifteen constructs were stabilised with ET-LCP, ESS-LCP or UEF (five constructs each). The constructs were loaded under both axial and torsional directions to determine construct stiffness.Objectives
Methods
A fracture of the hip is the most common serious orthopaedic
injury, and surgical site infection (SSI) is one of the most significant
complications, resulting in increased mortality, prolonged hospital
stay and often the need for further surgery. Our aim was to determine
whether high dose dual antibiotic impregnated bone cement decreases the
rate of infection. A quasi-randomised study of 848 patients with an intracapsular
fracture of the hip was conducted in one large teaching hospital
on two sites. All were treated with a hemiarthroplasty. A total
of 448 patients received low dose single-antibiotic impregnated
cement (control group) and 400 patients received high dose dual-antibiotic impregnated
cement (intervention group). The primary outcome measure was deep
SSI at one year after surgery.Aims
Patients and Methods
We aimed to identify the pattern of nerve injury associated with
paediatric supracondylar fractures of the humerus. Over a 17 year period, between 1996 and 2012, 166 children were
referred to our specialist peripheral nerve injury unit. From examination
of the medical records and radiographs were recorded the nature
of the fracture, associated vascular and neurological injury, treatment
provided and clinical course.Aims
Patients and Methods
The aim of this study was to report the incidence
of arthrofibrosis of the knee and identify risk factors for its development
following a fracture of the tibial plateau. We carried out a retrospective
review of 186 patients (114 male, 72 female) with a fracture of
the tibial plateau who underwent open reduction and internal fixation.
Their mean age was 46.4 years (19 to 83) and the mean follow-up
was16.0 months (6 to 80). A total of 27 patients (14.5%) developed arthrofibrosis requiring
a further intervention. Using multivariate regression analysis,
the use of a provisional external fixator (odds ratio (OR) 4.63,
95% confidence interval (CI) 1.26 to 17.7, p = 0.021) was significantly
associated with the development of arthrofibrosis. Similarly, the
use of a continuous passive movement (CPM) machine was associated
with significantly less development of arthrofibrosis (OR = 0.32,
95% CI 0.11 to 0.83, p = 0.024). The effect of time in an external
fixator was found to be significant, with each extra day of external
fixation increasing the odds of requiring manipulation under anaesthesia
(MUA) or quadricepsplasty by 10% (OR = 1.10, p = 0.030). High-energy
fracture, surgical approach, infection and use of tobacco were not
associated with the development of arthrofibrosis. Patients with
a successful MUA had significantly less time to MUA (mean 2.9 months; Based our results, CPM following operative fixation for a fracture
of the tibial plateau may reduce the risk of the development of
arthrofibrosis, particularly in patients who also undergo prolonged
provisional external fixation. Cite this article:
Our aim was to compare the one-year post-operative
outcomes following retention or removal of syndesmotic screws in
adult patients with a fracture of the ankle that was treated surgically.
A total of 51 patients (35 males, 16 females), with a mean age of
33.5 years (16 to 62), undergoing fibular osteosynthesis and syndesmotic
screw fixation, were randomly allocated to retention of the syndesmotic
screw or removal at three months post-operatively. The two groups
were comparable at baseline. One year post-operatively, there was no significant difference
in the mean Olerud–Molander ankle score (82.4 retention We conclude that removal of a syndesmotic screw produces no significant
functional, clinical or radiological benefit in adult patients who
are treated surgically for a fracture of the ankle. Cite this article:
A high rate of complications is associated with open reduction and internal fixation of Sanders type 4 fractures of the calcaneum. We assessed the long-term outcome of 83 Sanders type 4 comminuted intra-articular fractures of the calcaneum in 64 patients who underwent non-operative treatment between 1999 and 2005. Each fracture was treated by closed reduction and immobilisation in a long leg cast. Patients were reviewed every three months in the first year, and every six months thereafter. At each visit, the involved ankles were assessed by the American Orthopaedic Foot and Ankle Society (AOFAS) criteria. The degree of fracture healing and the presence of osteoarthritis were assessed. At a mean follow-up of 51 months (24 to 70) the mean AOFAS score was 72 (52 to 92). Osteoarthritis was scored radiologically using Graves’ classification and was evident in the subtalar joints of 75 ankles (90%) on x-ray and in all ankles on CT scans, of which 20 were grade 0 or 1, 39 grade 2, and 24 grade 3. A non-operative approach to treating these fractures may be simpler, less expensive, easier to administer with fewer complications, and may be better tolerated than surgery, by many patients.
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.
Our aim was to compare polylevolactic acid screws
with titanium screws when used for fixation of the distal tibiofibular
syndesmosis at mid-term follow-up. A total of 168 patients, with
a mean age of 38.5 years (18 to 72) who were randomly allocated
to receive either polylevolactic acid (n = 86) or metallic (n =
82) screws were included. The Baird scoring system was used to assess
the overall satisfaction and functional recovery post-operatively.
The demographic details and characteristics of the injury were similar
in the two groups. The mean follow-up was 55.8 months (48 to 66).
The Baird scores were similar in the two groups at the final follow-up.
Patients in the polylevolactic acid group had a greater mean dorsiflexion
(p = 0.011) and plantar-flexion of the injured ankles (p <
0.001).
In the same group, 18 patients had a mild and eight patients had
a moderate foreign body reaction. In the metallic groups eight had
mild and none had a moderate foreign body reaction (p <
0.001).
In total, three patients in the polylevolactic acid group and none
in the metallic group had heterotopic ossification (p = 0.246). We conclude that both screws provide adequate fixation and functional
recovery, but polylevolactic acid screws are associated with a higher
incidence of foreign body reactions. Cite this article:
Bicondylar tibial plateau fractures result from
high-energy injuries. Fractures of the tibial plateau can involve
the tibial tubercle, which represents a disruption to the extensor
mechanism and logically must be stabilised. The purpose of this
study was to identify the incidence of an independent tibial tubercle
fracture in bicondylar tibial plateau fractures, and to report management
strategies and potential complications. We retrospectively reviewed
a prospectively collected orthopaedic trauma database for the period
January 2003 to December 2008, and identified 392 bicondylar fractures
of the tibial plateau, in which 85 tibial tubercle fractures (21.6%)
were identified in 84 patients. There were 60 men and 24 women in
our study group, with a mean age of 45.4 years (18 to 71). In 84 fractures
open reduction and internal fixation was undertaken, either with
screws alone (23 patients) or with a plate and screws (61 patients).
The remaining patient was treated non-operatively. In all, 52 fractures
were available for clinical and radiological assessment at a mean
follow-up of 58.5 weeks (24 to 94). All fractures of the tibial
tubercle united, but 24 of 54 fractures (46%) required a secondary
procedure for their tibial plateau fracture. Four patients reported
pain arising from prominent tubercle plates and screws, which in
one patient required removal. Tibial tubercle fractures occurred
in over one-fifth of the bicondylar tibial plateau fractures in
our series. Fixation is necessary and can be reliably performed
with screws alone or with a screw and plate, which restores the
extensor mechanism and facilitates early knee flexion. Cite this article:
A series of 26 children was referred to our specialist unit with a ‘pink pulseless hand’ following a supracondylar fracture of the distal humerus after a mean period of three months (4 days to 12 months) except for one referred after almost three years. They were followed up for a mean of 15.5 years (4 to 26). The neurovascular injuries and resulting impairment in function and salvage procedures were recorded. The mean age at presentation was 8.6 years (2 to 12). There were eight girls and 18 boys. Only four of the 26 patients had undergone immediate surgical exploration before referral and three of these four had a satisfactory outcome. In one child the brachial artery had been explored unsuccessfully at 48 hours. As a result 23 of the 26 children presented with established ischaemic contracture of the forearm and hand. Two responded to conservative stretching. In the remaining 21 the antecubital fossa was explored. The aim of surgery was to try to improve the function of the hand and forearm, to assess nerve, vessel and muscle damage, to relieve entrapment and to minimise future disturbance of growth. Based on our results we recommend urgent exploration of the vessels and nerves in a child with a ‘pink pulseless hand’, not relieved by reduction of a supracondylar fracture of the distal humerus and presenting with persistent and increasing pain suggestive of a deepening nerve lesion and critical ischaemia.
Heterotopic ossification occurring after the use of commercially available bone morphogenetic proteins has not been widely reported. We describe four cases of heterotopic ossification in patients treated with either recombinant bone morphogenetic protein 2 or recombinant bone morphogenetic protein 7. We found that while some patients were asymptomatic, heterotopic ossification which had occurred around a joint often required operative excision with good results.
This paper reports the cost of outpatient venous
thromboembolism (VTE) prophylaxis following 388 injuries of the lower
limb requiring immobilisation in our institution, from a total of
7408 new patients presenting between May and November 2011. Prophylaxis
was by either self-administered subcutaneous dalteparin (n = 128)
or oral dabigatran (n = 260). The mean duration of prophylaxis per
patient was 46 days (6 to 168). The total cost (pay and non-pay)
for prophylaxis with dalteparin was £107.54 and with dabigatran
was £143.99. However, five patients in the dalteparin group required
nurse administration (£23 per home visit), increasing the cost of
dalteparin to £1142.54 per patient. The annual cost of VTE prophylaxis
in a busy trauma clinic treating 12 700 new patients (2010/11), would
be
£92 526.33 in the context of an income for trauma of £1.82 million,
which represents 5.3% of the outpatient tariff. Outpatient prophylaxis in a busy trauma clinic is achievable
and affordable in the context of the clinical and financial risks
involved. Cite this article:
We describe the results of 287 intra-articular fractures of the calcaneum in 247 patients treated by minimally-invasive reduction and K-wire fixation between 1994 and 2003. There were 210 men (85%) and 37 women (15%). The most common cause of injury was a fall from a height in 237 patients (96%). Fracture classification was based on the method described by Sanders and Essex-Lopresti. All patients were operated on within 21 days of injury and 89% (220) within 48 hours. The reduction was graded as nearly anatomical (less than 2 mm residual articular displacement and satisfactory overall alignment) in 212 (73.9%) fractures. There were 20 cases (7%) of superficial pin-track infection and five (1.7%) of deep infection. All healed at a mean of 6 weeks (3 to 19). Loss of reduction was observed in 13 fractures (4.5%) and a musculocutaneous flap was needed in three (1%). The results were evaluated in 176 patients (205 fractures) with a mean age of 44.3 years (13 to 67), available for follow-up at a mean of 43.4 months (25 to 87) using the Creighton-Nebraska Health Foundation Assessment score. The mean score was 83.9 points (63 to 100). There were 29 (16.5%) excellent, 98 (55.7%) good, 26 (14.8%) fair and 23 (13%) poor results. A total of 130 patients (73.9%) were able to return to their original occupation at a mean of 5.6 months (3.2 to 12.5) after the injury. Semi-open reduction and percutaneous fixation is an effective treatment for displaced intra-articular fractures of the calcaneum.
Neurogenic heterotopic ossification (NHO) is
a disorder of aberrant bone formation affecting one in five patients sustaining
a spinal cord injury or traumatic brain injury. Ectopic bone forms
around joints in characteristic patterns, causing pain and limiting
movement especially around the hip and elbow. Clinical sequelae
of neurogenic heterotopic ossification include urinary tract infection,
pressure injuries, pneumonia and poor hygiene, making early diagnosis
and treatment clinically compelling. However, diagnosis remains
difficult with more investigation needed. Our pathophysiological
understanding stems from mechanisms of basic bone formation enhanced
by evidence of systemic influences from circulating humor factors
and perhaps neurological ones. This increasing understanding guides
our implementation of current prophylaxis and treatment including
the use of non-steroidal anti-inflammatory drugs, bisphosphonates,
radiation therapy and surgery and, importantly, should direct future, more
effective ones.
Osteochondral injuries, if not treated adequately, often lead
to severe osteoarthritis. Possible treatment options include refixation
of the fragment or replacement therapies such as Pridie drilling,
microfracture or osteochondral grafts, all of which have certain
disadvantages. Only refixation of the fragment can produce a smooth
and resilient joint surface. The aim of this study was the evaluation
of an ultrasound-activated bioresorbable pin for the refixation of
osteochondral fragments under physiological conditions. In 16 Merino sheep, specific osteochondral fragments of the medial
femoral condyle were produced and refixed with one of conventional
bioresorbable pins, titanium screws or ultrasound-activated pins.
Macro- and microscopic scoring was undertaken after three months. Objectives
Methods
Most fractures of the radial head are stable
undisplaced or minimally displaced partial fractures without an associated
fracture of the elbow or forearm or ligament injury, where stiffness
following non-operative management is the primary concern. Displaced
unstable fractures of the radial head are usually associated with other
fractures or ligament injuries, and restoration of radiocapitellar
contact by reconstruction or prosthetic replacement of the fractured
head is necessary to prevent subluxation or dislocation of the elbow
and forearm. In fractures with three or fewer fragments (two articular
fragments and the neck) and little or no metaphyseal comminution,
open reduction and internal fixation may give good results. However,
fragmented unstable fractures of the radial head are prone to early
failure of fixation and nonunion when fixed. Excision of the radial
head is associated with good long-term results, but in patients
with instability of the elbow or forearm, prosthetic replacement
is preferred. This review considers the characteristics of stable and unstable
fractures of the radial head, as well as discussing the debatable
aspects of management, in light of the current best evidence. Cite this article:
We carried out a retrospective review of 47 intra-articular fractures of the calcaneum treated by open reduction and internal fixation in 45 patients by a single surgeon between 1993 and 2001. The fractures were evaluated before operation by plain radiographs and a CT scan using Sanders’ classification. Osteosynthesis involved a lateral approach and the use of the AO calcaneal plate. The mean follow-up was for ten years (7 to 15). Clinical assessment included the American Orthopaedic Foot and Ankle Society Score (AOFAS), the Creighton-Nebraska Score, the Kerr, Prothero, Atkins Score and the SF-36 Health Questionnaire. The radiological evaluation consisted of lateral and axial views of the os calcis. Arthritic changes in the subtalar joint were assessed with an internal oblique view and were graded using the Morrey and Wiedeman scale. There were 18 excellent (38.3%), 17 good (36.2%), three fair (6.3%) and nine poor (19.2%) results. Five patients had a superficial wound infection and five others eventually had a subtalar arthrodesis because of continuing pain. Restoration of Böhler’s angle was associated with a better outcome. The degree of arthritic change in the subtalar joint did not correlate with the outcome scores or Sanders’ classification. Prompt osteosynthesis should be considered for intra-articular fractures of the calcaneum in order to restore the shape of the hindfoot and Böhler’s angle.
Techniques for fixation of fractures of the lateral
malleolus have remained essentially unchanged since the 1960s, but
are associated with complication rates of up to 30%. The fibular
nail is an alternative method of fixation requiring a minimal incision
and tissue dissection, and has the potential to reduce the incidence
of complications. We reviewed the results of 105 patients with unstable fractures
of the ankle that were fixed between 2002 and 2010 using the Acumed
fibular nail. The mean age of the patients was 64.8 years (22 to
95), and 80 (76%) had significant systemic medical comorbidities.
Various different configurations of locking screw were assessed
over the study period as experience was gained with the device.
Nailing without the use of locking screws gave satisfactory stability
in only 66% of cases (4 of 6). Initial locking screw constructs
rendered between 91% (10 of 11) and 96% (23 of 24) of ankles stable.
Overall, seven patients had loss of fixation of the fracture and
there were five post-operative wound infections related to the distal
fibula. This lead to the development of the current technique with
a screw across the syndesmosis in addition to a distal locking screw.
In 21 patients treated with this technique there have been no significant
complications and only one superficial wound infection. Good fracture
reduction was achieved in all of these patients. The mean physical
component Short-Form 12, Olerud and Molander score, and American Academy
of Orthopaedic Surgeons Foot and Ankle outcome scores at a mean
of six years post-injury were 46 (28 to 61), 65 (35 to 100) and
83 (52 to 99), respectively. There have been no cases of fibular
nonunion. Nailing of the fibula using our current technique gives good
radiological and functional outcomes with minimal complications,
and should be considered in the management of patients with an unstable
ankle fracture.
The ideal form of fixation for displaced, extra-articular
fractures of the distal tibia remains controversial. In the UK, open
reduction and internal fixation with locking-plates and intramedullary
nailing are the two most common forms of treatment. Both techniques
provide reliable fixation but both are associated with specific
complications. There is little information regarding the functional
recovery following either procedure. We performed a randomised pilot trial to determine the functional
outcome of 24 adult patients treated with either a locking-plate
(n = 12) or an intramedullary nailing (n = 12). At six months, there
was an adjusted difference of 13 points in the Disability Rating
Index in favour of the intramedullary nail. However, this was not
statistically significant in this pilot trial (p = 0.498). A total
of seven patients required further surgery in the locking-plate
group and one in the intramedullary nail group. This study suggests that there may be clinically relevant, functional
differences in patients treated with nail
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:
Stable fractures of the ankle can be successfully treated non-operatively by a below-knee plaster cast. In some centres, patients with this injury are routinely administered low-molecular-weight heparin, to reduce the risk of deep-vein thrombosis (DVT). We have assessed the incidence of DVT in 100 patients in the absence of any thromboprophylaxis. A colour Doppler duplex ultrasound scan was done at the time of the removal of the cast. Five patients did develop DVT, though none had clinical signs suggestive of it. One case involved the femoral and another the popliteal vein. No patient developed pulmonary embolism. As the incidence of DVT after ankle fractures is low, we do not recommend routine thromboprophylaxis.
The extended lateral L-shaped approach for the treatment of displaced intra-articular fractures of the calcaneum may be complicated by wound infection, haematoma, dehiscence and injury to the sural nerve. In an effort to reduce the risk of problems with wound healing a technique was developed that combined open reduction and fixation of the joint fragments and of the anterior process with percutaneous reduction and screw fixation of the tuberosity. A group of 24 patients with unilateral isolated closed Sanders type II and III fractures was treated using this technique and compared to a similar group of 26 patients managed by the extended approach and lateral plating. The operation was significantly shorter (p <
0.001) in the first group, but more minor secondary procedures and removal of heel screws were necessary. There were no wound complications in this group, whereas four minor complications occurred in the second group. The accuracy and maintenance of reduction, and ultimate function were equivalent.
Between 2000 and 2006 we performed salvage tibiotalar arthrodesis in 17 diabetic patients (17 ankles) with grossly unstable ankles caused by bimalleolar fractures complicated by Charcot neuro-arthropathy. There were ten women and seven men with a mean age of 61.6 years (57 to 69). A crossed-screw technique was used. Two screws were used in eight patients and three screws in nine. Additional graft from the malleoli was used in all patients. The mean follow-up was 26 months (12 to 48) and the mean time to union was 5.8 months (4 to 8). A stable ankle was achieved in 14 patients (82.4%), nine of whom had bony fusion and five had a stiff fibrous union. The results were significantly better in underweight patients, in those in whom surgery had been performed three to six months after the onset of acute Charcot arthropathy, in those who had received anti-resorptive medication during the acute stage, in those without extensive peripheral neuropathy, and in those with adequate peripheral oxygen saturation (>
95%). The arthrodesis failed because of avascular necrosis of the talus in only three patients (17.6%), who developed grossly unstable, ulcerated hindfeet, and required below-knee amputation.
We studied prospectively the regional inflammatory response to a unilateral distal radial fracture in 114 patients at eight to nine weeks after injury and again at one year. Our aim was to identify patients at risk for a delayed recovery and particularly those likely to develop complex regional pain syndrome. In order to quantify clinically the inflammatory response, a regional inflammatory score was developed. In addition, blood samples were collected from the antecubital veins of both arms for comparative biochemical and blood-gas analysis. The severity of the inflammatory response was related to the type of treatment (Kruskal-Wallis test, p = 0.002). A highly significantly-positive correlation was found between the regional inflammatory score and the length of time to full recovery (r2 = 0.92, p = 0.01, linear regession). A regional inflammatory score of 5 points with a sensitivity of 100% but a specificity of only 16% also identified patients at risk of complex regional pain syndrome. None of the biochemical parameters studied correlated with regional inflammatory score or predicted the development of complex regional pain syndrome. Our study suggests that patients with a distal radial fracture and a regional inflammatory score of 5 points or more at eight to nine weeks after injury should be considered for specific anti-inflammatory treatment.
We compared the outcome of closed intramedullary nailing with minimally invasive plate osteosynthesis using a percutaneous locked compression plate in patients with a distal metaphyseal fracture in a prospective study. A total of 85 patients were randomised to operative stabilisation either by a closed intramedullary nail (44) or by minimally invasive osteosynthesis with a compression plate (41). Pre-operative variables included the patients’ age and the side and pattern of the fracture. Peri-operative variables were the operating time and the radiation time. Postoperative variables were wound problems, the time to union of the fracture, the functional American Orthopaedic Foot and Ankle surgery score and removal of hardware. We found no significant difference in the pre-operative variables or in the time to union in the two groups. However, the mean radiation time and operating time were significantly longer in the locked compression plate group (3.0 We conclude that both closed intramedullary nailing and a percutaneous locked compression plate can be used safely to treat Orthopaedic Trauma Association type-43A distal metaphyseal fractures of the tibia. However, closed intramedullary nailing has the advantage of a shorter operating and radiation time and easier removal of the implant. We therefore prefer closed intramedullary nailing for patients with these fractures.
We have reviewed our experience in managing 11 patients who sustained an indirect sternal fracture in combination with an upper thoracic spinal injury between 2003 and 2006. These fractures have previously been described as ‘associated’ fractures, but since the upper thorax is an anatomical entity composed of the upper thoracic spine, ribs and sternum joined together, we feel that the term ‘fractures of the upper transthoracic cage’ is a better description. These injuries are a challenge because they are unusual and easily overlooked. They require a systematic clinical and radiological examination to identify both lesions. This high-energy trauma gives severe devastating concomitant injuries and CT with contrast and reconstruction is essential after resuscitation to confirm the presence of all the lesions. The injury level occurs principally at T4–T5 and at the manubriosternal joint. These unstable fractures need early posterior stabilisation and fusion or, if treated conservatively, a very close follow-up.
Fracture-dislocations of the tarsometatarsal (Lisfranc) joints are frequently overlooked or misdiagnosed at initial presentation. This is a comparative cohort study over a period of five years comparing primary open reduction and internal fixation in 22 patients (23 feet) with secondary corrective arthrodesis in 22 patients (22 feet) who presented with painful malunion at a mean of 22 months (1.5 to 45) after injury. In the first group primary treatment by open reduction and internal fixation for eight weeks with Kirschner-wires or screws was undertaken, in the second group treatment was by secondary corrective arthrodesis. There was one deep infection in the first group. In the delayed group there was one complete and one partial nonunion. In each group 20 patients were available for follow-up at a mean of 36 months (24 to 89) after operation. The mean American Orthopaedic Foot and Ankle Society midfoot score was 81.4 (62 to 100) after primary treatment and 71.8 (35 to 88) after corrective arthrodesis (t-test; p = 0.031). We conclude that primary treatment by open reduction and internal fixation of tarsometatarsal fracture-dislocations leads to improved functional results, earlier return to work and greater patient satisfaction than secondary corrective arthrodesis, which remains a useful salvage procedure providing significant relief of pain and improvement in function.
Although supracondylar fracture is a very common elbow injury in childhood, there is no consensus on the timing of surgery, approach for open reduction and positioning of fixation wires. We report our ten-year experience between 1993 and 2003 in 291 children. Most fractures (285; 98%) were extension injuries, mainly Gartland types II (73; 25%) and III (163; 56%). Six (2%) were open fractures and a neurovascular deficit was seen in 12 (4%) patients. Of the 236 children (81%) who required an operation, 181 (77%) were taken to theatre on the day of admission. Most (177; 75%) of the operations were performed by specialist registrars. Fixation was by crossed Kirschner wires in 158 of 186 (85%) patients and open reduction was necessary in 52 (22%). A post-operative neurological deficit was seen in nine patients (4%) and three (1%) required exploration of the ulnar nerve. Only 22 (4%) patients had a long-term deformity, nine (3%) from malreduction and three (1%) because of growth arrest, but corrective surgery for functional limitation was required in only three (1%) patients.
A minimally-invasive procedure using percutaneous reduction and external fixation can be carried out for Sanders’ type II, III and IV fractures of the os calcis. We have treated 54 consecutive closed displaced fractures of the calcaneum involving the articular surface in 52 patients with the Orthofix Calcaneal Mini-Fixator. Patients were followed up for a mean of 49 months (27 to 94) and assessed clinically with the Maryland Foot Score and radiologically with radiographs and CT scans, evaluated according to the Score Analysis of Verona. The clinical results at follow-up were excellent or good in 49 cases (90.7%), fair in two (3.7%) and poor in three (5.6%). The mean pre-operative Böhler’s angle was 6.98° (5.95° to 19.86°), whereas after surgery the mean value was 21.94° (12.58° to 31.30°) (p <
0.01). Excellent results on CT scanning were demonstrated in 24 cases (44.4%), good in 25 (46.3%), fair in three (5.6%) and poor in two (3.7%). Transient local osteoporosis was observed in ten patients (18.5%), superficial pin track infection in three (5.6%), and three patients (5.6%) showed thalamic displacement following unadvised early weight-bearing. The clinical results appear to be comparable with those obtainable with open reduction and internal fixation, with the advantages of reduced risk using a minimally-invasive technique.
We retrospectively reviewed 183 children with a simple fracture of the distal radius, with or without fracture of the ulna, treated by closed reduction and cast immobilisation. The fracture redisplaced after an initial, acceptable closed reduction in 46 (25%). Complete initial displacement was identified as the most important factor leading to redisplacement. Other contributing factors were the presence of an ipsilateral distal ulnar fracture, and the reduction of completely displaced fractures under deep sedation or local haematoma block. We recommend that completely displaced fractures of the distal radius in children should be reduced under general anaesthesia, and fixed by primary percutaneous Kirschner wires even when a satisfactory closed reduction has been achieved.
Between 1998 and 2002, 37 neuropathies in 32 patients with a displaced supracondylar fracture of the humerus who were referred to a nerve injury unit were identified. There were 19 boys and 13 girls with a mean age of 7.9 years (3.6 to 11.3). A retrospective review of these injuries was performed. The ulnar nerve was injured in 19, the median nerve in ten and the radial nerve in eight cases. Fourteen neuropathies were noted at the initial presentation and 23 were diagnosed after treatment of the fracture. After referral, exploration of the nerve was planned for 13 patients. Surgery was later cancelled in three because of clinical recovery. Six patients underwent neurolysis alone. Excision of neuroma and nerve grafting were performed in four. At follow-up, 26 patients had an excellent, five a good and one a fair outcome.
