Whiplash injury is surrounded by controversy in both the medical and legal world. The debate on whether it is either a potentially serious medical condition or a social problem is ongoing. This paper briefly examines a selection of studies on low velocity whiplash injury (LVWI) and whiplash associated disorder (WAD) and touches upon the pathophysiological and epidemiological considerations, cultural and geographical differences and the effect of litigation on chronicity. The study concludes that the evidence for significant physical injury after LVWI is poor, and if significant disability is present after such injury, it will have to be explained in terms of psychosocial factors.
We present a case series of ten metal-on-polyethylene total hip
arthroplasties (MoP THAs) with delayed dislocation associated with
unrecognised adverse local tissue reaction due to corrosion at the
trunnion and pseudotumour formation. The diagnosis was not suspected in nine of the ten patients (six
female/four male; mean age 66 years), despite treatment in a specialist
unit (mean time from index surgery to revision was 58 months, 36
to 84). It was identified at revision surgery and subsequently confirmed
by histological examination of resected tissue. Pre-operative assessment
and culture results ruled out infection. A variety of treatment
strategies were used, including resection of the pseudotumour and
efforts to avoid recurrent dislocation. Aims

The repair of chondral lesions associated with
femoroacetabular impingement requires specific treatment in addition
to that of the impingement. In this single-centre retrospective
analysis of a consecutive series of patients we compared treatment
with microfracture (MFx) with a technique of enhanced microfracture
autologous matrix-induced chondrogenesis (AMIC). Acetabular grade III and IV chondral lesions measuring between
2 cm2 and 8 cm2 in 147 patients were treated
by MFx in 77 and AMIC in 70. The outcome was assessed using the
modified Harris hip score at six months and one, two, three, four
and five years post-operatively. The outcome in both groups was
significantly improved at six months and one year post-operatively.
During the subsequent four years the outcome in the MFx group slowly deteriorated,
whereas that in the AMIC group remained stable. Six patients in
the MFx group subsequently required total hip arthroplasty, compared
with none in the AMIC group We conclude that the short-term clinical outcome improves in
patients with acetabular chondral damage following both MFx and
AMIC. However, the AMIC group had better and more durable improvement,
particularly in patients with large (≥ 4 cm2) lesions. Cite this article:
Femoroacetabular Junction Impingement (FAI) describes abnormalities
in the shape of the femoral head–neck junction, or abnormalities
in the orientation of the acetabulum. In the short term, FAI can
give rise to pain and disability, and in the long-term it significantly increases
the risk of developing osteoarthritis. The Femoroacetabular Impingement
Trial (FAIT) aims to determine whether operative or non-operative
intervention is more effective at improving symptoms and preventing
the development and progression of osteoarthritis. FAIT is a multicentre superiority parallel two-arm randomised
controlled trial comparing physiotherapy and activity modification
with arthroscopic surgery for the treatment of symptomatic FAI.
Patients aged 18 to 60 with clinical and radiological evidence of
FAI are eligible. Principal exclusion criteria include previous
surgery to the index hip, established osteoarthritis (Kellgren–Lawrence
≥ 2), hip dysplasia (centre-edge angle <
20°), and completion
of a physiotherapy programme targeting FAI within the previous 12
months. Recruitment will take place over 24 months and 120 patients
will be randomised in a 1:1 ratio and followed up for three years.
The two primary outcome measures are change in hip outcome score
eight months post-randomisation (approximately six-months post-intervention
initiation) and change in radiographic minimum joint space width
38 months post-randomisation. ClinicalTrials.gov: NCT01893034. Cite this article: Aims

We determined the efficacy of a devitalised autograft
(n = 13) and allograft (n = 16) cortical strut bone graft combined
with long-stem endoprosthetic reconstruction in the treatment of
massive tumours of the lower limb. A total of 29 patients (18 men:11
women, mean age 20.1 years (12 to 45) with a ratio of length of
resection to that of the whole prosthesis of >
50% were treated
between May 2003 and May 2012. The mean follow-up was 47 months
(15 to 132). The stem of the prosthesis was introduced through bone
graft struts filled with cement, then cemented into the residual
bone. Bone healing was achieved in 23 patients (86%). The mean Musculoskeletal
Tumour Society functional score was 85% (57 to 97). The five-year
survival rate of the endoprostheses was 81% (95% confidence intervals
67.3 to 92.3). The mean length of devitalised autografts and allografts
was 8.6 cm (5 to 15), which increased the ratio of the the length
of the stem of the prosthesis to that of the whole length of the
prosthesis from a theoretical 35% to an actual 55%. Cortical strut bone grafting and long-stem endoprosthetic reconstruction
is an option for treating massive segmental defects following resection
of a tumour in the lower limb. Patients can regain good function
with a low incidence of aseptic loosening. The strut graft and the
residual bone together serve as a satisfactory bony environment
for a revision prosthesis, if required, once union is achieved. Cite this article:
Between 2002 and 2011, 81 patients with a traumatic total brachial
plexus injury underwent reconstruction by double free muscle transfer
(DFMT, 47 cases), single muscle transfer (SMT, 16 cases) or nerve
transfers (NT, 18 cases). They were evaluated for functional outcome and quality of life
(QoL) using the Disability of Arm, Shoulder and Hand questionnaire,
both pre- and post-operatively. The three groups were compared and
followed-up for at least 24 months.Aims
Methods
As adverse events related to metal on metal hip
arthroplasty have been better understood, there has been increased
interest in toxicity related to the high circulating levels of cobalt ions.
However, distinguishing true toxicity from benign elevations in
cobalt levels can be challenging. The purpose of this review is
to examine the use of cobalt alloys in total hip arthroplasty, to
review the methods of measuring circulating cobalt levels, to define
a level of cobalt which is considered pathological and to review
the pathophysiology, risk factors and treatment of cobalt toxicity.
To the best of our knowledge, there are 18 published cases where
cobalt metal ion toxicity has been attributed to the use of cobalt-chromium
alloys in hip arthroplasty. Of these cases, the great majority reported
systemic toxic reactions at serum cobalt levels more than 100 μg/L.
This review highlights some of the clinical features of cobalt toxicity,
with the goal that early awareness may decrease the risk factors
for the development of cobalt toxicity and/or reduce its severity. Take home message: Severe adverse events can arise from the release
of cobalt from metal-on-metal arthroplasties, and as such, orthopaedic
surgeons should not only be aware of the presenting problems, but
also have the knowledge to treat appropriately. Cite this article:
There is a high risk of the development of avascular
necrosis of the femoral head and nonunion after the treatment of
displaced subcapital fractures of the femoral neck in patients aged
<
50 years. We retrospectively analysed the results following
fixation with two cannulated compression screws and a vascularised
iliac bone graft. We treated 18 women and 16 men with a mean age
of 38.5 years (20 to 50) whose treatment included the use of an
iliac bone graft based on the ascending branch of lateral femoral
circumflex artery. There were 20 Garden grade III and 14 grade IV
fractures. Clinical and radiological outcomes were evaluated. The
mean follow-up was 5.4 years (2 to 10). In 30 hips (88%) union was
achieved at a mean of 4.4 months (4 to 6). Nonunion occurred in
four hips (12%) and these patients had a mean age of 46.5 years
(42 to 50) and underwent revision to a hip replacement six months
after operation. The time to union was dependent on age with younger
patients achieving earlier union (p <
0.001). According to the
Harris hip score which was available for 27 of the 30 hips with
satisfactory union, excellent results were obtained in 15 (score ≥ 90
points), fair in ten (score 80 to 90 points), and poor in two hips
(≤ 80 points). One patient aged 48 years developed avascular necrosis
of femoral head six years after operation and underwent total hip
replacement. The management of displaced subcapital fractures of the femoral
neck, in patients aged <
50 years, with two cannulated compression
screws and an iliac bone graft based on the ascending branch of
lateral femoral circumflex artery, gives satisfactory results with
a low rate of complication including avascular necrosis and nonunion. Cite this article:
Ceramic-on-metal (CoM) is a relatively new bearing
combination for total hip arthroplasty (THA) with few reported outcomes.
A total of 287 CoM THAs were carried out in 271 patients (mean age
55.6 years (20 to 77), 150 THAs in female patients, 137 in male)
under the care of a single surgeon between October 2007 and October
2009. With the issues surrounding metal-on-metal bearings the decision
was taken to review these patients between March and November 2011,
at a mean follow-up of 34 months (23 to 45) and to record pain,
outcome scores, radiological analysis and blood ion levels. The
mean Oxford Hip Score was 19.2 (12 to 53), 254 patients with 268
hips (95%) had mild/very mild/no pain, the mean angle of inclination
of the acetabular component was 44.8o (28o to
63o), 82 stems (29%) had evidence of radiolucent lines
of >
1 mm in at least one Gruen zone and the median levels of cobalt
and chromium ions in the blood were 0.83 μg/L (0.24 μg/L to 27.56 μg/L)
and 0.78 μg/L (0.21 μg/L to 8.84 μg/L), respectively. The five-year
survival rate is 96.9% (95% confidence interval 94.7% to 99%). Due to the presence of radiolucent lines and the higher than
expected levels of metal ions in the blood, we would not recommend
the use of CoM THA without further long-term follow-up. We plan
to monitor all these patients regularly. Cite this article:
Clinical and radiological data were reviewed for all patients
with mucopolysaccharidoses (MPS) with thoracolumbar kyphosis managed
non-operatively or operatively in our institution. In all 16 patients were included (eight female: eight male; 50%
male), of whom nine had Hurler, five Morquio and two Hunter syndrome.
Six patients were treated non-operatively (mean age at presentation
of 6.3 years; 0.4 to 12.9); mean kyphotic progression +1.5o/year;
mean follow-up of 3.1 years (1 to 5.1) and ten patients operatively (mean
age at presentation of 4.7 years; 0.9 to 14.4); mean kyphotic progression
10.8o/year; mean follow-up of 8.2 years; 4.8 to 11.8)

The traditional techniques involving an oblique
tunnel or triangular wedge resection to approach a central or mixed-type
physeal bar are hindered by poor visualisation of the bar. This
may be overcome by a complete transverse osteotomy at the metaphysis
near the growth plate or a direct vertical approach to the bar.
Ilizarov external fixation using small wires allows firm fixation
of the short physis-bearing fragment, and can also correct an associated angular
deformity and permit limb lengthening. We accurately approached and successfully excised ten central-
or mixed-type bars; six in the distal femur, two in the proximal
tibia and two in the distal tibia, without damaging the uninvolved
physis, and corrected the associated angular deformity and leg-length
discrepancy. Callus formation was slightly delayed because of periosteal
elevation and stretching during resection of the bar. The resultant
resection of the bar was satisfactory in seven patients and fair
in three as assessed using a by a modified Williamson–Staheli classification. Cite this article:

Arthritis of the wrist is a painful disabling
condition that has various causes and presentations. The traditional treatment
has been a total wrist fusion at a price of the elimination of movement.
However, forms of treatment which allow the preservation of movement
are now preferred. Modern arthroplasties of the wrist are still
not sufficiently robust to meet the demands of many patients, nor
do they restore normal kinematics of the wrist. A preferable compromise
may be selective excision and partial fusion of the wrist using
knowledge of the aetiology and pattern of degenerative change to
identify which joints can be sacrificed and which can be preserved. This article provides an overview of the treatment options available
for patients with arthritis of the wrist and an algorithm for selecting
an appropriate surgical strategy. Cite this article:
Hypovitaminosis D has been identified as a common
risk factor for fragility fractures and poor fracture healing. Epidemiological
data on vitamin D deficiency have been gathered in various populations,
but the association between vertebral fragility fractures and hypovitaminosis
D, especially in males, remains unclear. The purpose of this study
was to evaluate serum levels of 25-hydroxyvitamin D (25-OH D) in
patients presenting with vertebral fragility fractures and to determine
whether patients with a vertebral fracture were at greater risk
of hypovitaminosis D than a control population. Furthermore, we
studied the seasonal variations in the serum vitamin D levels of
tested patients in order to clarify the relationship between other
known risk factors for osteoporosis and vitamin D levels. We measured
the serum 25-OH D levels of 246 patients admitted with vertebral
fractures (105 men, 141 female, mean age 69 years, Cite this article:
