To evaluate graft healing of decellularized porcine superflexor tendon (pSFT) xenograft in an ovine anterior cruciate ligament (ACL) reconstruction model using two femoral fixation devices. Also, to determine if pSFT allows functional recovery of gait as compared with the preoperative measurements. A total of 12 sheep underwent unilateral single-bundle ACL reconstruction using pSFT. Two femoral fixation devices were investigated: Group 1 (n = 6) used cortical suspensory fixation (Endobutton CL) and Group 2 (n = 6) used cross-pin fixation (Stratis ST). A soft screw was used for tibial fixation. Functional recovery was quantified using force plate analysis at weeks 5, 8, and 11. The sheep were euthanized after 12 weeks and comprehensive histological analysis characterized graft healing at the graft-bone interface and the intra-articular graft (ligamentization).Aims
Methods
Little is known about the risk factors that predispose to a rupture of the posterior cruciate ligament (PCL). Identifying risk factors is the first step in trying to prevent a rupture of the PCL from occurring. The morphology of the knee in patients who rupture their PCL may differ from that of control patients. The purpose of this study was to identify any variations in bone morphology that are related to a PCL. We compared the anteroposterior (AP), lateral, and Rosenberg view radiographs of 94 patients with a ruptured PCL to a control group of 168 patients matched by age, sex, and body mass index (BMI), but with an intact PCL after a knee injury. Statistical shape modelling software was used to assess the shape of the knee and determine any difference in anatomical landmarks.Aims
Patients and Methods
The glenohumeral joint is the most frequently dislocated articulation, but possibly due to the lower prevalence of posterior shoulder dislocations, approximately 50% to 79% of posterior glenohumeral dislocations are missed at initial presentation. The aim of this study was to systematically evaluate the most recent evidence involving the aetiology of posterior glenohumeral dislocations, as well as the diagnosis and treatment. A systematic search was conducted using PubMed (MEDLINE), Web of Science, Embase, and Cochrane (January 1997 to September 2017), with references from articles also evaluated. Studies reporting patients who experienced an acute posterior glenohumeral joint subluxation and/or dislocation, as well as the aetiology of posterior glenohumeral dislocations, were included.Aims
Materials and Methods
The aims of this study were to evaluate the morphology of the ankle in patients with an osteochondral lesion of the talus using 3D CT, and to investigate factors that predispose to this condition. The study involved 19 patients (19 ankles) who underwent surgery for a medial osteochondral lesion (OLT group) and a control group of 19 healthy patients (19 ankles) without ankle pathology. The mean age was significantly lower in the OLT group than in the control group (27.0 Aims
Patients and Methods
Identifying predictors of compartment syndrome in the foot after
a fracture of the calcaneus may lead to earlier diagnosis and treatment.
The aim of our study was to identify any such predictors. We retrospectively reviewed 303 patients (313 fractures) with
a fracture of the calcaneus who presented to us between October
2008 and September 2016. The presence of compartment syndrome and
potential predictors were identified by reviewing their medical
records. Potential predictors included age, gender, concomitant
foot injury, mechanism of injury, fracture classification, time
from injury to admission, underlying illness, use of anticoagulant/antiplatelet
agents, smoking status and occupation. Associations with predictors
were analyzed using logistic regression analysis.Aims
Patients and Methods
In this study, we compared the pain behaviour and osteoarthritis (OA) progression between anterior cruciate ligament transection (ACLT) and osteochondral injury in surgically-induced OA rat models. OA was induced in the knee joints of male Wistar rats using transection of the ACL or induction of osteochondral injury. Changes in the percentage of high limb weight distribution (%HLWD) on the operated hind limb were used to determine the pain behaviour in these models. The development of OA was assessed and compared using a histological evaluation based on the Osteoarthritis Research Society International (OARSI) cartilage OA histopathology score.Objectives
Methods
To validate the English language Forgotten Joint Score-12 (FJS-12)
as a tool to evaluate the outcome of hip and knee arthroplasty in
a United Kingdom population. All patients undergoing surgery between January and August 2014
were eligible for inclusion. Prospective data were collected from
205 patients undergoing total hip arthroplasty (THA) and 231 patients
undergoing total knee arthroplasty (TKA). Outcomes were assessed
with the FJS-12 and the Oxford Hip and Knee Scores (OHS, OKS) pre-operatively,
then at six and 12 months post-operatively. Internal consistency,
convergent validity, effect size, relative validity and ceiling
effects were determined.Aims
Patients and 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
Patients and Methods
The management of open lower limb fractures in the United Kingdom
has evolved over the last ten years with the introduction of major
trauma networks (MTNs), the publication of standards of care and
the wide acceptance of a combined orthopaedic and plastic surgical approach
to management. The aims of this study were to report recent changes
in outcome of open tibial fractures following the implementation
of these changes. Data on all patients with an open tibial fracture presenting
to a major trauma centre between 2011 and 2012 were collected prospectively.
The treatment and outcomes of the 65 Gustilo Anderson Grade III
B tibial fractures were compared with historical data from the same
unit. Aims
Patients and Methods
Hip and groin injuries are common in athletes
who take part in high level sports. Adductor muscle tendon injuries represent
a small but important number of these injuries. Avulsion of the
tendons attached to the symphysis pubis has previously been described:
these can be managed both operatively and non-operatively. We describe
an uncommon variant of this injury, namely complete avulsion of
the adductor sleeve complex: this includes adductor longus, pectineus
and rectus abdominis. We go on to describe a surgical technique
which promotes a full return to the pre-injury level of sporting
activity. Over a period of ten years, 15 high-level athletes with an MRI-confirmed
acute adductor complex avulsion injury (six to 34 days old) underwent
surgical repair. The operative procedure consisted of anatomical
re-attachment of the avulsed tissues in each case and mesh reinforcement
of the posterior inguinal wall in seven patients. All underwent a
standardised rehabilitation programme, which was then individualised
to be sport-specific. One patient developed a superficial wound infection, which was
successfully treated with antibiotics. Of the 15 patients, four
complained of transient local numbness which resolved in all cases.
All patients (including seven elite athletes) returned to their
previous level of participation in sport. Cite this article:
Paediatric fractures are common and can cause
significant morbidity. Socioeconomic deprivation is associated with an
increased incidence of fractures in both adults and children, but
little is known about the epidemiology of paediatric fractures.
In this study we investigated the effect of social deprivation on
the epidemiology of paediatric fractures. We compiled a prospective database of all fractures in children
aged <
16 years presenting to the study centre. Demographics,
type of fracture, mode of injury and postcode were recorded. Socioeconomic
status quintiles were assigned for each child using the Scottish
Index for Multiple Deprivation (SIMD). We found a correlation between increasing deprivation and the
incidence of fractures (r = 1.00, p <
0.001). In the most deprived
group the incidence was 2420/100 000/yr, which diminished to 1775/100
000/yr in the least deprived group. The most deprived children were more likely to suffer a fracture
as a result of a fall (odds ratio (OR) = 1.5, p <
0.0001), blunt
trauma (OR = 1.5, p = 0.026) or a road traffic accident (OR = 2.7,
p <
0.0001) than the least deprived. These findings have important implications for public health
and preventative measures. Cite this article:
Antegrade intramedullary nailing of fractures of the shaft of the humerus is reported to cause impairment of the shoulder joint. We have reviewed 33 patients with such fractures to assess how many had injuries to the ipsilateral shoulder. All had an MR scan of the shoulder within 11 days of injury. The unaffected shoulder was also scanned as a control. There was evidence of abnormality in 21 of the shoulders (63.6%) on the injured side; ten had bursitis of the subacromial space, five evidence of a partial tear of the rotator cuff, one a complete rupture of the supraspinatus tendon, four inflammatory changes in the acromioclavicular joint and one a fracture of the coracoid process. These injuries may contribute to pain and dysfunction of the shoulder following treatment, and their presence indicates that antegrade nailing is only partly, if at all, responsible for these symptoms.
The Essex-Lopresti injury (ELI) of the forearm
is a rare and serious condition which is often overlooked, leading
to a poor outcome. The purpose of this retrospective case study was to establish
whether early surgery can give good medium-term results. From a group of 295 patients with a fracture of the radial head,
12 patients were diagnosed with ELI on MRI which confirmed injury
to the interosseous membrane (IOM) and ligament (IOL). They were
treated by reduction and temporary Kirschner (K)-wire stabilisation
of the distal radioulnar joint (DRUJ). In addition, eight patients
had a radial head replacement, and two a radial head reconstruction. All patients were examined clinically and radiologically 59 months
(25 to 90) after surgery when the mean Mayo Modified Wrist Score
(MMWS) was 88.4 (78 to 94), the mean Mayo Elbow Performance Scores
(MEPS) 86.7 (77 to 95) and the mean disabilities of arm, shoulder
and hand (DASH) score 20.5 (16 to 31): all of these indicate a good outcome. In case of a high index of suspicion for ELI in patients with
a radial head fracture, we recommend the following: confirmation
of IOM and IOL injury with an early MRI scan; early surgery with
reduction and temporary K-wire stabilisation of the DRUJ; preservation
of the radial head if at all possible or replacement if not, and
functional bracing in supination. This will increase the prospect
of a good result, and avoid the complications of a missed diagnosis
and the difficulties of late treatment. Cite this article:
Fractures of the tibial shaft are common injuries,
but there are no long-term outcome data in the era of increased surgical
management. The aim of this prospective study was to assess the
clinical and functional outcome of this injury at 12 to 22 years.
Secondary aims were to determine the short- and long-term mortality,
and if there were any predictors of clinical or functional outcome
or mortality. From a prospective trauma database of 1502 tibial
shaft fractures in 1474 consecutive adult patients, we identified
a cohort of 1431 tibial diaphyseal fractures in 1403 patients, who
fitted our inclusion criteria. There were 1024 men, and mean age
at injury was 40.6 years. Fractures were classified according to
the AO system, and open fractures graded after Gustilo and Anderson.
Requirement of fasciotomy, time to fracture union, complications,
incidence of knee and ankle pain at long-term follow-up, changes in
employment and the patients’ social deprivation status were recorded.
Function was assessed at 12 to 22 years post-injury using the Short
Musculoskeletal Function Assessment and short form-12 questionnaires.
Long-term functional outcome data was available for 568 of the surviving
patients, 389 were deceased and 346 were lost to follow-up. Most
fractures (90.7%, n = 1363) united without further intervention.
Fasciotomies were performed in 11.5% of patients; this did not correlate
with poorer functional outcome in the long term. Social deprivation
was associated with a higher incidence of injury but had no impact
on long-term function. The one-year mortality in those over 75 years
of age was 29 (42%). At long-term follow-up, pain and function scores
were good. However, 147 (26%) reported ongoing knee pain, 62 (10%)
reported ankle pain and 97 (17%) reported both. Such joint pain correlated
with poorer functional outcome. Cite this article:
A suspected fracture of the scaphoid remains difficult to manage despite advances in knowledge and imaging methods. Immobilisation and restriction of activities in a young and active patient must be balanced against the risks of nonunion associated with an undiagnosed and undertreated fracture of the scaphoid. The assessment of diagnostic tests for a suspected fracture of the scaphoid must take into account two important factors. First, the prevalence of true fractures among suspected fractures is low, which greatly reduces the probability that a positive test will correspond with a true fracture, as false positives are nearly as common as true positives. This situation is accounted for by Bayesian statistics. Secondly, there is no agreed reference standard for a true fracture, which necessitates the need for an alternative method of calculating diagnostic performance characteristics, based upon a statistical method which identifies clinical factors tending to associate (latent classes) in patients with a high probability of fracture. The most successful diagnostic test to date is MRI, but in low-prevalence situations the positive predictive value of MRI is only 88%, and new data have documented the potential for false positive scans. The best strategy for improving the diagnosis of true fractures among suspected fractures of the scaphoid may well be to develop a clinical prediction rule incorporating a set of demographic and clinical factors which together increase the pre-test probability of a fracture of the scaphoid, in addition to developing increasingly sophisticated radiological tests.
