Some surgeons are reluctant to perform a reverse
total shoulder arthroplasty (RTSA) on both shoulders because of concerns
regarding difficulty with activities of daily living post-operatively
as a result of limited rotation of the shoulders. Nevertheless,
we hypothesised that outcomes and patient satisfaction following
bilateral RTSA would be comparable to those following unilateral
RTSA. A single-surgeon RTSA registry was reviewed for patients who underwent
bilateral staged RTSA with a minimum follow-up of two years. A unilateral
RTSA matched control was selected for each shoulder in those patients
undergoing bilateral procedures. The Constant–Murley score (CMS), American
Shoulder and Elbow Surgeons (ASES) score, Subjective Shoulder Values
(SSV), visual analogue scale (VAS) for pain, range of movement and
strength were measured pre- and post-operatively. The mean CMS,
ASES, SSV, VAS scores, strength and active forward elevation were
significantly improved
(all p <
0.01) following each operation in those undergoing bilateral
procedures. The mean active external rotation (p = 0.63 and p =
0.19) and internal rotation (p = 0.77 and p = 0.24) were not significantly
improved. The improvement in the mean ASES score after the first
RTSA was greater than the improvement in its control group (p =
0.0039). The improvement in the mean CMS, ASES scores and active
forward elevation was significantly less after the second RTSA than
in its control group (p = 0.0244, p = 0.0183, and p = 0.0280, respectively).
Pain relief and function significantly improved after each RTSA
in those undergoing a bilateral procedure. Bilateral RTSA is thus a reasonable form of treatment for patients
with severe bilateral rotator cuff deficiency, although inferior
results may be seen after the second procedure compared with the
first. Cite this article:

Minimally invasive total knee replacement (MIS-TKR)
has been reported to have better early recovery than conventional
TKR. Quadriceps-sparing (QS) TKR is the least invasive MIS procedure,
but it is technically demanding with higher reported rates of complications
and outliers. This study was designed to compare the early clinical
and radiological outcomes of TKR performed by an experienced surgeon
using the QS approach with or without navigational assistance (NA),
or using a mini-medial parapatellar (MP) approach. In all, 100 patients
completed a minimum two-year follow-up: 30 in the NA-QS group, 35
in the QS group, and 35 in the MP group. There were no significant
differences in clinical outcome in terms of ability to perform a
straight-leg raise at 24 hours (p = 0.700), knee score (p = 0.952),
functional score (p = 0.229) and range of movement (p = 0.732) among
the groups. The number of outliers for all three radiological parameters
of mechanical axis, frontal femoral component alignment and frontal
tibial component alignment was significantly lower in the NA-QS
group than in the QS group (p = 0.008), but no outlier was found
in the MP group. In conclusion, even after the surgeon completed a substantial
number of cases before the commencement of this study, the supplementary
intra-operative use of computer-assisted navigation with QS-TKR
still gave inferior radiological results and longer operating time,
with a similar outcome at two years when compared with a MP approach. Cite this article:
The June 2013 Children’s orthopaedics Roundup360 looks at: whether reaching a diagnosis is more difficult than previously thought; adolescent and paediatric DDH; the A-frame orthosis and Legg-Calvé-Perthes’ disease; failure of hip surgery in patients with cerebral palsy; adolescent rotator cuff injuries; paediatric peripheral nerve injuries; predicting residual deformity following Ponseti treatment; and the Dunn procedure.
To assess the effectiveness of a modified tibial tubercle osteotomy
as a treatment for arthroscopically diagnosed chondromalacia patellae. A total of 47 consecutive patients (51 knees) with arthroscopically
proven chondromalacia, who had failed conservative management, underwent
a modified Fulkerson tibial tubercle osteotomy. The mean age was
34.4 years (19.6 to 52.2). Pre-operatively, none of the patients
exhibited signs of patellar maltracking or instability in association
with their anterior knee pain. The minimum follow-up for the study
was five years (mean 72.6 months (62 to 118)), with only one patient
lost to follow-up.Objectives
Methods
We performed a systematic review of the literature to determine
whether earlier surgical repair of acute rotator cuff tear (ARCT)
leads to superior post-operative clinical outcomes. The MEDLINE, Embase, CINAHL, Web of Science, Cochrane Libraries,
controlled-trials.com and clinicaltrials.gov databases were searched
using the terms: ‘rotator cuff’, or ‘supraspinatus’, or ‘infraspinatus’,
or ‘teres minor’, or ‘subscapularis’ AND ‘surgery’ or ‘repair’.
This gave a total of 15 833 articles. After deletion of duplicates
and the review of abstracts and full texts by two independent assessors,
15 studies reporting time to surgery for ARCT repair were included.
Studies were grouped based on time to surgery <
3 months (group
A, seven studies), or >
3 months (group B, eight studies). Weighted
means were calculated and compared using Student’s Aims
Methods
Children with congenital vertical talus (CVT)
have been treated with extensive soft-tissue releases, with a high
rate of complications. Recently, reverse Ponseti-type casting followed
by percutaneous reduction and fixation has been described, with
excellent results in separate cohorts of children with CVT, of either
idiopathic or teratological aetiology. There are currently no studies
that compare the outcome in these two types. We present a prospective cohort
of 13 children (21 feet) with CVT of both idiopathic and teratological
aetiology, in which this technique has been used. Clinical, radiological
and parent-reported outcomes were obtained at a mean follow-up of
36 months (8 to 57). Six children (nine feet) had associated neuromuscular
conditions or syndromes; the condition was idiopathic in seven children
(12 feet). Initial correction was achieved in all children, with significant
improvement in all radiological parameters. Recurrence was seen
in ten feet. Modification of the technique to include limited capsulotomy
at the initial operation may reduce the risk of recurrence. The reverse Ponseti-type technique is effective in the initial
correction of CVT of both idiopathic and teratological aetiology.
Recurrence is a problem in both these groups, with higher rates
than first reported in the original paper. However, these rates
are less than those reported after open surgical release. Cite this article:

This retrospective study compared post-operative
epidural analgesia (E), continuous peripheral nerve blocks (CPNB) and
morphine infusion (M) in 68 children undergoing limb reconstruction
with circular frames. The data collected included episodes of severe
pain, post-operative duration of analgesia, requirement for top-up
analgesia, number of osteotomies, side effects and complications.
There was a significant difference between the number of episodes
of severe pain in patients receiving a morphine infusion and those
receiving epidurals or CPNB (M
We retrospectively reviewed the records of 1150
computer-assisted total knee replacements and analysed the clinical
and radiological outcomes of 45 knees that had arthritis with a
pre-operative recurvatum deformity. The mean pre-operative hyperextension
deformity of 11° (6° to 15°), as measured by navigation at the start
of the operation, improved to a mean flexion deformity of 3.1° (0°
to 7°) post-operatively. A total of 41 knees (91%) were managed
using inserts ≤ 12.5 mm thick, and none had mediolateral laxity
>
2 mm from a mechanical axis of 0° at the end of the surgery. At
a mean follow-up of 26.4 months (13 to 48) there was significant
improvement in the mean Knee Society, Oxford knee and Western Ontario
and McMaster Universities Osteoarthritis Index scores compared with
the pre-operative values. The mean knee flexion improved from 105°
(80° to 125°) pre-operatively to 131° (120° to 145°), and none of
the limbs had recurrent recurvatum. These early results show that total knee replacement using computer
navigation and an algorithmic approach for arthritic knees with
a recurvatum deformity can give excellent radiological and functional
outcomes without recurrent deformity.

The treatment of hip dysplasia should be customised
for patients individually based on radiographic findings, patient
age, and the patient’s overall articular cartilage status. In many
patients, restoration of hip anatomy as close to normal as possible
with a PAO is the treatment of choice. Cite this article:
We undertook a randomised controlled trial to
compare the piriformis-sparing approach with the standard posterior approach
used for total hip replacement (THR). We recruited 100 patients
awaiting THR and randomly allocated them to either the piriformis-sparing
approach or the standard posterior approach. Pre- and post-operative
care programmes and rehabilitation regimes were identical for both
groups. Observers were blinded to the allocation throughout; patients
were blinded until the two-week assessment. Follow-up was at six
weeks, three months, one year and two years. In all 11 patients
died or were lost to follow-up. There was no significant difference between groups for any of
the functional outcomes. However, for patients in the piriformis-sparing
group there was a trend towards a better six-minute walk test at
two weeks and greater patient satisfaction at six weeks. The acetabular
components were less anteverted (p = 0.005) and had a lower mean
inclination angle (p = 0.02) in the piriformis-sparing group. However,
in both groups the mean component positions were within Lewinnek’s
safe zone. Surgeons perceived the piriformis-sparing approach to
be significantly more difficult than the standard approach (p =
0.03), particularly in obese patients. In conclusion, performing THR through a shorter incision involving
sparing piriformis is more difficult and only provides short-term
benefits compared with the standard posterior approach.
This is a case series of prospectively gathered
data characterising the injuries, surgical treatment and outcomes
of consecutive British service personnel who underwent a unilateral
lower limb amputation following combat injury. Patients with primary,
unilateral loss of the lower limb sustained between March 2004 and
March 2010 were identified from the United Kingdom Military Trauma
Registry. Patients were asked to complete a Short-Form (SF)-36 questionnaire.
A total of 48 patients were identified: 21 had a trans-tibial amputation,
nine had a knee disarticulation and 18 had an amputation at the
trans-femoral level. The median New Injury Severity Score was 24 (mean
27.4 (9 to 75)) and the median number of procedures per residual
limb was 4 (mean 5 (2 to 11)). Minimum two-year SF-36 scores were
completed by 39 patients (81%) at a mean follow-up of 40 months
(25 to 75). The physical component of the SF-36 varied significantly
between different levels of amputation (p = 0.01). Mental component
scores did not vary between amputation levels (p = 0.114). Pain
(p = 0.332), use of prosthesis (p = 0.503), rate of re-admission
(p = 0.228) and mobility (p = 0.087) did not vary between amputation
levels. These findings illustrate the significant impact of these injuries
and the considerable surgical burden associated with their treatment.
Quality of life is improved with a longer residual limb, and these
results support surgical attempts to maximise residual limb length. Cite this article:
In a randomised trial involving 598 patients
with 600 trochanteric fractures of the hip, the fractures were treated with
either a sliding hip screw (n = 300) or a Targon PF intramedullary
nail (n = 300). The mean age of the patients was 82 years (26 to
104). All surviving patients were reviewed at one year with functional
outcome assessed by a research nurse blinded to the treatment used.
The intramedullary nail was found to have a slightly increased mean
operative time (46 minutes ( In summary, both implants produced comparable results but there
was a tendency to better return of mobility for those treated with
the intramedullary nail.
Narrow, well-defined radiolucent lines commonly observed at the bone-implant interface of unicompartmental knee replacement tibial components have been referred to as physiological radiolucencies. These should be distinguished from pathological radiolucencies, which are poorly defined, wide and progressive, and associated with loosening and infection. We studied the incidence and clinical significance of tibial radiolucent lines in 161 Oxford unicondylar knee replacements five years after surgery. All the radiographs were aligned with fluoroscopic control to obtain views parallel to the tibial tray to reveal the tibial bone-implant interface. We found that 49 knees (30%) had complete, 52 (32%) had partial and 60 (37%) had no radiolucent lines. There was no relationship between the incidence of radiolucent lines and patient factors such as gender, body mass index and activity, or operative factors including the status of the anterior cruciate ligament and residual varus deformity. Nor was any statistical relationship established between the presence of radiolucent lines and clinical outcome, particularly pain, assessed by the Oxford Knee score and the American Knee Society score. We conclude that radiolucent lines are common after Oxford unicompartmental knee replacement but that their aetiology remains unclear. Radiolucent lines were not a source of adverse symptoms or pain. Therefore, when attempting to identify a source of postoperative pain after Oxford unicompartmental knee replacement the presence of a physiological radiolucency should be ignored.
