The December 2012 Spine Roundup360 looks at: the Japanese neck disability index; adjacent segment degeneration; sacroiliac loads determined by limb length discrepancy; whether epidural steroids improve outcome in lumbar disc herniation; spondylodiscitis in infancy; total pedicle screws; and iliac crest autograft complications.
The October 2014 Shoulder &
Elbow Roundup360 looks at: PRP is not effective in tennis elbow; eccentric physiotherapy effective in subacromial pain; dexamethasone in shoulder surgery; arthroscopic remplissage for engaging Hill-Sach’s lesions; a consistent approach to subacromial impingement; delay in fixation of proximal humeral fractures detrimental to outcomes.
Our aim was to compare the outcome of arthroscopic
release for frozen shoulder in patients with and without diabetes.
We prospectively compared the outcome in 21 patients with and 21
patients without diabetes, two years post-operatively. The modified
Constant score was used as the outcome measure. The mean age of
the patients was 54.5 years (48 to 65; male:female ratio: 18:24),
the mean pre-operative duration of symptoms was 8.3 months (6 to
13) and the mean pre-operative modified Constant scores were 36.6

We present our experience of managing patients
with iatropathic brachial plexus injury after delayed fixation of
a fracture of the clavicle. It is a retrospective cohort study of
patients treated at our peripheral nerve injury unit and a single
illustrative case report. We identified 21 patients in whom a brachial
plexus injury occurred as a direct consequence of fixation of a
fracture of the clavicle between September 2000 and September 2011. The predominant injury involved the C5/C6 nerves, upper trunk,
lateral cord and the suprascapular nerve. In all patients, the injured
nerve was found to be tethered to the under surface of the clavicle
by scar tissue at the site of the fracture and was usually associated
with pathognomonic neuropathic pain and paralysis. Delayed fixation of a fracture of the clavicle, especially between
two and four weeks after injury, can result in iatropathic brachial
plexus injury. The risk can be reduced by thorough release of the
tissues from the inferior surface of the clavicle before mobilisation
of the fracture fragments. If features of nerve damage appear post-operatively
urgent specialist referral is recommended. Cite this article:
We present the ten- to 15-year follow-up of 31
patients (34 knees), who underwent an Elmslie-Trillat tibial tubercle osteotomy
for chronic, severe patellar instability, unresponsive to non-operative
treatment. The mean age of the patients at the time of surgery was
31 years (18 to 46) and they were reviewed post-operatively, at
four years (2 to 8) and then at 12 years (10 to 15). All patients
had pre-operative knee radiographs and Cox and Insall knee scores. Superolateral
portal arthroscopy was performed per-operatively to document chondral
damage and after the osteotomy to assess the stability of the patellofemoral
joint. A total of 28 knees (82%) had a varying degree of damage
to the articular surface. At final follow-up 25 patients (28 knees)
were available for review and underwent clinical examination, radiographs
of the knee, and Cox and Insall scoring. Six patients who had no
arthroscopic chondral abnormality showed no or only early signs
of osteoarthritis on final radiographs; while 12 patients with lower
grade chondral damage (grade 1 to 2) showed early to moderate signs
of osteoarthritis and six out of ten knees with higher grade chondral
damage (grade 3 to 4) showed marked evidence of osteoarthritis;
four of these had undergone a knee replacement. In the 22 patients
(24 knees) with complete follow-up, 19 knees (79.2%) were reported
to have a good or excellent outcome at four years, while 15 knees
(62.5%) were reported to have the same at long-term follow-up. The
functional and radiological results show that the extent of pre-operatively
sustained chondral damage is directly related to the subsequent
development of patellofemoral osteoarthritis. Cite this article:
In a decidedly upper limb themed series of reviews this edition of Cochrane Corner summarises four new and updated reviews published by the Cochrane Bone, Joint and Muscle Trauma Group over the last few months. The tenacious reviewers at the Cochrane collaboration have turned their beady eyes to conservative treatments for shoulder dislocations and clavicle fractures along with evaluation of femoral nerve blocks in knee replacement and how to best manage entrapment injuries in children.
The Unified Classification System (UCS) emphasises
the key principles in the assessment and management of peri-prosthetic
fractures complicating partial or total joint replacement. We tested the inter- and intra-observer agreement for the UCS
as applied to the pelvis and femur using 20 examples of peri-prosthetic
fracture in 17 patients. Each subtype of the UCS was represented
by at least one case. Specialist orthopaedic surgeons (experts)
and orthopaedic residents (pre-experts) assessed reliability on
two separate occasions. For the pelvis, the UCS showed inter-observer agreement of 0.837
(95% confidence intervals (CI) 0.798 to 0.876) for the experts and
0.728 (95% CI 0.689 to 0.767) for the pre-experts. The intra-observer
agreement for the experts was 0.861 (95% CI 0.760 to 0.963) and
0.803 (95% 0.688 to 0.918) for the pre-experts. For the femur, the
UCS showed an inter-observer kappa value of 0.805 (95% CI 0.765
to 0.845) for the experts and a value of 0.732 (95% CI 0.690 to 0.773)
for the pre-experts. The intra-observer agreement was 0.920 (95%
CI 0.867 to 0.973) for the experts, and 0.772 (95% CI 0.652 to 0.892)
for the pre-experts. This corresponds to a substantial and ‘almost
perfect’ inter- and intra-observer agreement for the UCS for peri-prosthetic
fractures of the pelvis and femur. We hope that unifying the terminology of these injuries will
assist in their assessment, treatment and outcome. Cite this article:
A total of 92 patients with symptoms for over
six months due to subacromial impingement of the shoulder, who were
being treated with physiotherapy, were included in this study. While
continuing with physiotherapy they waited a further six months for
surgery. They were divided into three groups based on the following
four clinical and radiological criteria: temporary benefit following
steroid injection, pain in the mid-arc of abduction, a consistently positive
Hawkins test and radiological evidence of impingement. Group A fulfilled
all four criteria, group B three criteria and group C two criteria.
A total of nine patients improved while waiting for surgery and
were excluded, leaving 83 who underwent arthroscopic subacromial
decompression (SAD). The new Oxford shoulder score was recorded
pre-operatively and at three and 12 months post-operatively. A total of 51 patients (group A) had a significant improvement
in the mean shoulder score from 18 (13 to 22) pre-operatively to
38 (35 to 42) at three months (p <
0.001). The mean score in
this group was significantly better than in group B (21 patients)
and C (11 patients) at this time. At one year patients in all groups
showed improvement in scores, but patients in group A had a higher
mean score (p = 0.01). At one year patients in groups A and B did
better than those in group C (p = 0.01). Arthroscopic SAD is a beneficial intervention in selected patients.
The four criteria could help identify patients in whom it is likely
to be most effective.
We are currently facing an epidemic of periprosthetic
fractures around the hip. They may occur either during surgery or
post-operatively. Although the acetabulum may be involved, the femur
is most commonly affected. We are being presented with new, difficult
fracture patterns around cemented and cementless implants, and we
face the challenge of an elderly population who may have grossly
deficient bone and may struggle to rehabilitate after such injuries.
The correct surgical management of these fractures is challenging.
This article will review the current choices of implants and techniques
available to deal with periprosthetic fractures of the femur. Cite this article:
In order to achieve satisfactory reduction of
complex distal humeral fractures, adequate exposure of the fracture fragments
and the joint surface is required. Several surgical exposures have
been described for distal humeral fractures. We report our experience
using the anconeus pedicle olecranon flip osteotomy approach. This
involves detachment of the triceps along with a sliver of olecranon,
which retains the anconeus pedicle. We report the use of this approach
in ten patients (six male, four female) with a mean age of 38.4
years (28 to 51). The mean follow-up was 15 months (12 to 18) with
no loss to follow-up. Elbow function was graded using the Mayo Score.
The results were excellent in four patients, good in five and fair
in one patient. The mean time to both fracture and osteotomy union
was 10.6 weeks (8 to 12) and 7.1 weeks (6 to 8), respectively. We
found this approach gave reliably good exposure for these difficult
fractures enabling anatomical reduction and bicondylar plating without
complications. Cite this article:
The October 2012 Foot &
Ankle Roundup360 looks at: ankle arthrodesis in young active patients; the Bologna-Oxford total ankle replacements; significant failure and revision rates for total ankle arthroplasty; surgical treatment of Achilles tendon rupture; selective plantar fascia release; whether removal of metalwork can resolve foot pain; allografting of osteochondral lesions; distracting from osteoarthritis; and ultrasound-guided minimally invasive surgery.
The aim of this study was to perform a cost–utility
analysis of total hip (THR) and knee replacement (TKR). Arthritis is
a disabling condition that leads to long-term deterioration in quality
of life. Total joint replacement, despite being one of the greatest
advances in medicine of the modern era, has recently come under
scrutiny. The National Health Service (NHS) has competing demands,
and resource allocation is challenging in times of economic restraint. Patients
who underwent THR (n = 348) or TKR (n = 323) between January and
July 2010 in one Scottish region were entered into a prospective
arthroplasty database. A health–utility score was derived from the
EuroQol (EQ-5D) score pre-operatively and at one year, and was combined
with individual life expectancy to derive the quality-adjusted life years
(QALYs) gained. Two-way analysis of variance was used to compare
QALYs gained between procedures, while controlling for baseline
differences. The number of QALYs gained was higher after THR than
after TKR (6.5 Cite this article:
Between 1995 and 2006, five intra-articular osteotomies of the head of the radius were performed in patients with symptomatic healed displaced articular fractures. Pre-operatively, all patients complained of persistent painful clicking on movement. Only patients with mild or no degenerative changes of the radial head and capitellum were considered for osteotomy. The operations were performed at a mean of 8.2 months (4 to 13) after injury and the patients were reviewed at a mean of 5.5 years (15 months to 12 years) after the osteotomy. The average Mayo Elbow Performance Index Score improved significantly from 74 before to 88 after operation, with four patients rated as good or excellent (p <
0.05). The subjective patient satisfaction score was 8.4 on a ten-point scale. All osteotomies healed and there were no complications. In this small series intra-articular osteotomy of the head of the radius was a safe and effective treatment for symptomatic intra-articular malunion without advanced degenerative changes.
Previous studies have identified clinical and
demographic risk factors for recurrence in the treatment of idiopathic clubfoot
(congenital talipes equinovarus). Evertor muscle activity is not
usually considered amongst them. This study aimed to evaluate whether
recurrence could be predicted by demographic, clinical and gait
parameters. From a series of 103 children with clubfeet, 67 had
completed a follow-up of two years: 41 male and 26 female, 38 with idiopathic
and 29 with non-idiopathic deformities. The mean age was 3.2 years
(2.1 to 6.3). Primary correction was obtained in all 38 children
(100%) with an idiopathic deformity, and in 26 of 29 patients (90%)
with a non-idiopathic deformity. Overall, 60 children (90%) complied
with the abduction brace regime. At a mean follow-up of 31.4 months (24
to 62), recurrence was noted in six children (15.8%) in the idiopathic
and 14 children (48.3%) in the non-idiopathic group. Significant
correlation was found between poor evertor activity and recurrence
in both groups. No statistically significant relationship was found
between the rate of recurrence and the severity of the initial deformity,
the age at the time of treatment, the number of casts required or
the compliance with the brace. After correction of idiopathic and non-idiopathic clubfoot using
the Ponseti method, only poor evertor muscle activity was statistically
associated with recurrence. The identification of risk factors for
recurrent deformity allows clinicians to anticipate problems and
advocate early additional treatment to improve muscle balance around
the ankle. Cite this article:
Scapulothoracic fusion (STF) for painful winging
of the scapula in neuromuscular disorders can provide effective pain
relief and functional improvement, but there is little information
comparing outcomes between patients with dystrophic and non-dystrophic
conditions. We performed a retrospective review of 42 STFs in 34
patients with dystrophic and non-dystrophic conditions using a multifilament
trans-scapular, subcostal cable technique supported by a dorsal
one-third semi-tubular plate. There were 16 males and 18 females
with a mean age of 30 years (15 to 75) and a mean follow-up of 5.0
years (2.0 to 10.6). The mean Oxford shoulder score improved from
20 (4 to 39) to 31 (4 to 48). Patients with non-dystrophic conditions
had lower overall functional scores but achieved greater improvements
following STF. The mean active forward elevation increased from
59° (20° to 90°) to 97° (30° to 150°), and abduction from 51° (10°
to 90°) to 83° (30° to 130°) with a greater range of movement achieved
in the dystrophic group. Revision fusion for nonunion was undertaken
in five patients at a mean time of 17 months (7 to 31) and two required
revision for fracture. There were three pneumothoraces, two rib
fractures, three pleural effusions and six nonunions. The main risk
factors for nonunion were smoking, age and previous shoulder girdle surgery. STF is a salvage procedure that can provide good patient satisfaction
in 82% of patients with both dystrophic and non-dystrophic pathologies,
but there was a relatively high failure rate (26%) when poor outcomes
were analysed. Overall function was better in patients with dystrophic
conditions which correlated with better range of movement; however,
patients with non-dystrophic conditions achieved greater functional
improvement.
In this randomised controlled trial, we evaluated
the role of elastic compression using ankle injury stockings (AIS)
in the management of fractures of the ankle. A total of 90 patients
with a mean age of 47 years (16 to 79) were treated within 72 hours
of presentation with a fracture of the ankle, 31 of whom were treated
operatively and 59 conservatively, were randomised to be treated
either with compression by AIS plus an Aircast boot or Tubigrip
plus an Aircast boot. Male to female ratio was 36:54. The primary
outcome measure was the functional Olerud–Molander ankle score (OMAS).
The secondary outcome measures were; the American Orthopaedic Foot
and Ankle Society score (AOFAS); the Short Form (SF)-12v2 Quality
of Life score; and the frequency of deep vein thrombosis (DVT). Compression using AIS reduced swelling of the ankle at all time
points and improved the mean OMAS score at six months to 98 (95%
confidence interval (CI) 96 to 99) compared with a mean of 67 (95%
CI 62 to 73) for the Tubigrip group (p <
0.001). The mean AOFAS
and SF-12v2 scores at six months were also significantly improved
by compression. Of 86 patients with duplex imaging at four weeks,
five (12%) of 43 in the AIS group and ten (23%) of 43 in the Tubigrip
group developed a DVT (p = 0.26). Compression improved functional outcome and quality of life following
fracture of the ankle. DVTs were frequent, but a larger study would
be needed to confirm that compression with AISs reduces the incidence
of DVT. Cite this article:
Conventional methods of treating ankle fractures
in the elderly are associated with high rates of complication. We describe
the results of treating these injuries in 48 frail elderly patients
with a long calcaneotalotibial nail. The mean age of the group was 82 years (61 to 96) and 41 (85%)
were women. All were frail, with multiple medical comorbidities
and their mean American Society of Anaesthesiologists score was
3 (3 to 4). None could walk independently before their operation.
All the fractures were displaced and unstable; the majority (94%,
45 of 48) were low-energy injuries and 40% (19 of 48) were open. The overall mortality at six months was 35%. Of the surviving
patients, 90% returned to their pre-injury level of function. The
mean pre- and post-operative Olerud and Molander questionnaire scores
were 62 and 57 respectively. Complications included superficial
infection (4%, two of 48); deep infection (2%, one of 48); a broken
or loose distal locking screw (6%, three of 48); valgus malunion
(4%, two of 48); and one below-knee amputation following an unsuccessful
vascular operation. There were no cases of nonunion, nail breakage
or peri-prosthetic fracture. A calcaneotalotibial nail is an excellent device for treating
an unstable fracture of the ankle in the frail elderly patient.
It allows the patient to mobilise immediately and minimises the
risk of bone or wound problems. A long nail which crosses the isthmus
of the tibia avoids the risk of peri-prosthetic fracture associated
with shorter devices. Cite this article:
Back pain is a common symptom in children and
adolescents. Here we review the important causes, of which defects
and stress reactions of the pars interarticularis are the most common
identifiable problems. More serious pathology, including malignancy
and infection, needs to be excluded when there is associated systemic
illness. Clinical evaluation and management may be difficult and
always requires a thorough history and physical examination. Diagnostic
imaging is obtained when symptoms are persistent or severe. Imaging
is used to reassure the patient, relatives and carers, and to guide
management. Cite this article:
