Aims. To evaluate if union of clavicle fractures can be predicted at six weeks post-injury by the presence of bridging callus on ultrasound. Methods. Adult patients managed nonoperatively with a displaced mid-shaft clavicle were recruited
Indocyanine green (ICG) fluorescence angiography is an emerging technique that can provide detailed anatomical information during surgery. The purpose of this study is to determine whether ICG fluorescence angiography can be used to evaluate the blood flow of the rotator cuff tendon in the clinical setting. Twenty-six patients were evaluated from October 2016 to December 2017. The participants were categorized into three groups based on their diagnoses: the rotator cuff tear group; normal rotator cuff group; and adhesive capsulitis group. After establishing a posterior standard viewing portal, intravenous administration of ICG at 0.2 mg/kg body weight was performed, and fluorescence images were recorded. The time from injection of the drug to the beginning of enhancement of the observed area was measured. The hypovascular area in the rotator cuff was evaluated, and the ratio of the hypovascular area to the anterolateral area of the rotator cuff tendon was calculated (hypovascular area ratio).Objectives
Methods
Plating displaced proximal humeral fractures is associated with a high rate of screw perforation. Dynamization of the proximal screws might prevent these complications. The aim of this study was to develop and evaluate a new gliding screw concept for plating proximal humeral fractures biomechanically. Eight pairs of three-part humeral fractures were randomly assigned for pairwise instrumentation using either a prototype gliding plate or a standard PHILOS plate, and four pairs were fixed using the gliding plate with bone cement augmentation of its proximal screws. The specimens were cyclically tested under progressively increasing loading until perforation of a screw. Telescoping of a screw, varus tilting and screw migration were recorded using optical motion tracking.Aims
Methods
The aim of this study was to compare the pain caused by the application
of a tourniquet after exsanguination of the upper limb with that
occurring after simple elevation. We used 26 healthy volunteers (52 arms), each of whom acted as
their own matched control. The primary outcome measure was the total pain experienced by
each volunteer while the tourniquet was inflated for 20 minutes.
This was calculated as the area under the pain curve for each individual
subject. Secondary outcomes were pain at each time point; the total
pain experienced during the recovery phase; the ability to tolerate the
tourniquet and the time for full recovery after deflation of the
tourniquet. Aims
Patients and Methods
Necrotising soft-tissue infections (NSTIs) of
the upper limb are uncommon, but potentially life-threatening. We
used a national database to investigate the risk factors for amputation
of the limb and death. We extracted data from the Japanese Diagnosis Procedure Combination
database on 116 patients (79 men and 37 women) who had a NSTI of
the upper extremity between 2007 and 2010. The overall in-hospital mortality was 15.5%. Univariate analysis
of in-hospital mortality showed that the significant variables were
age (p = 0.015), liver dysfunction (p = 0.005), renal dysfunction
(P <
0.001), altered consciousness (p = 0.049), and sepsis (p
= 0.021). Logistic regression analysis showed that the factors associated with
death in hospital were age over 70 years (Odds Ratio (OR) 6.6; 95%
confidence interval (CI) 1.5 to 28.2; p = 0.011) and renal dysfunction
(OR 15.4; 95% CI 3.8 to 62.8; p <
0.001). Univariate analysis of limb amputation showed that the significant
variables were diabetes (p = 0.017) mellitus and sepsis (p = 0.001).
Multivariable logistic regression analysis showed that the factors
related to limb amputation were sepsis (OR 1.8; 95% CI 1.5 to 24.0;
p = 0.013) and diabetes mellitus (OR 1.6; 95% CI 1.1 to 21.1; p
= 0.038). For NSTIs of the upper extremity, advanced age and renal dysfunction
are both associated with a higher rate of in-hospital mortality.
Sepsis and diabetes mellitus are both associated with a higher rate
of amputation. Cite this article:
Traumatic brachial plexus injury causes severe functional impairment
of the arm. Elbow flexion is often affected. Nerve surgery or tendon
transfers provide the only means to obtain improved elbow flexion.
Unfortunately, the functionality of the arm often remains insufficient.
Stem cell therapy could potentially improve muscle strength and
avoid muscle-tendon transfer. This pilot study assesses the safety
and regenerative potential of autologous bone marrow-derived mononuclear
cell injection in partially denervated biceps. Nine brachial plexus patients with insufficient elbow flexion
(i.e., partial denervation) received intramuscular escalating doses
of autologous bone marrow-derived mononuclear cells, combined with
tendon transfers. Effect parameters included biceps biopsies, motor
unit analysis on needle electromyography and computerised muscle tomography,
before and after cell therapy.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

The purpose of this study was to compare the

To report the five-year results of a randomised controlled trial
examining the effectiveness of arthroscopic acromioplasty in the
treatment of stage II shoulder impingement syndrome. A total of 140 patients were randomly divided into two groups:
1) supervised exercise programme (n = 70, exercise group); and 2)
arthroscopic acromioplasty followed by a similar exercise programme
(n = 70, combined treatment group).Objectives
Methods
Most patients with a nightstick fracture of the
ulna are treated conservatively. Various techniques of immobilisation or
early mobilisation have been studied. We performed a systematic
review of all published randomised controlled trials and observational
studies that have assessed the outcome of these fractures following
above- or below-elbow immobilisation, bracing and early mobilisation.
We searched multiple electronic databases, related bibliographies and
other studies. We included 27 studies comprising 1629 fractures
in the final analysis. The data relating to the time to radiological
union and the rates of delayed union and nonunion could be pooled
and analysed statistically. We found that early mobilisation produced the shortest radiological
time to union (mean 8.0 weeks) and the lowest mean rate of nonunion
(0.6%). Fractures treated with above- or below-elbow immobilisation
and braces had longer mean radiological times to union (9.2 weeks,
9.2 weeks and 8.7 weeks, respectively) and higher mean rates of
nonunion (3.8%, 2.1% and 0.8%, respectively). There was no statistically
significant difference in the rate of non- or delayed union between
those treated by early mobilisation and the three forms of immobilisation
(p = 0.142 to p = 1.000, respectively). All the studies had significant
biases, but until a robust randomised controlled trial is undertaken
the best advice for the treatment of undisplaced or partially displaced
nightstick fractures appears to be early mobilisation, with a removable
forearm support for comfort as required. Cite this article:
In adults with brachial plexus injuries, lack
of active external rotation at the shoulder is one of the most common residual
deficits, significantly compromising upper limb function. There
is a paucity of evidence to address this complex issue. We present
our experience of isolated latissimus dorsi (LD) muscle transfer
to achieve active external rotation. This is a retrospective review
of 24 adult post-traumatic plexopathy patients who underwent isolated latissimus
dorsi muscle transfer to restore external rotation of the shoulder
between 1997 and 2010. All patients were male with a mean age of
34 years (21 to 57). All the patients underwent isolated LD muscle
transfer using a standard technique to correct external rotational
deficit. Outcome was assessed for improvement in active external rotation,
arc of movement, muscle strength and return to work. The mean improvement
in active external rotation from neutral was 24° (10° to 50°). The
mean increase in arc of rotation was 52° (38° to 55°). Mean power
of the external rotators was 3.5 Medical Research Council (MRC)
grades (2 to 5). A total of 21 patients (88%) were back in work by the time of
last follow up. Of these,
13 had returned to their pre-injury occupation. Isolated latissimus
dorsi muscle transfer provides a simple and reliable method of restoring
useful active external rotation in adults with brachial plexus injuries
with internal rotational deformity. Cite this article:
Instability after arthroplasty of the shoulder
is difficult to correct surgically. Soft-tissue procedures and revision surgery
using unconstrained anatomical components are associated with a
high rate of failure. The purpose of this study was to determine
the results of revision of an unstable anatomical shoulder arthroplasty
to a reverse design prosthesis. Between 2004 and 2007, 33 unstable
anatomical shoulder arthroplasties were revised to a reverse design.
The mean age of the patients was 71 years (53 to 86) and their mean
follow-up was 42 months (25 to 71). The mean time to revision was
26 months (4 to 164). Pain scores improved significantly (pre-operative
visual analogue scale (VAS) of 7.2 ( Cite this article:
Surgical repair of posterosuperior rotator cuff
tears has a poorer outcome and a higher rate of failure compared
with repairs of supraspinatus tears. In this
This study reports the clinical and sonographic
outcome of arthroscopic rotator cuff repair in patients aged ≥ 70 years
and aimed to determine factors associated with re-tear. A total
of 69 consecutive repairs were performed in 68 patients with a mean
age of 77 years (70 to 86). Constant-Murley scores were collected
pre-operatively and at one year post-operatively. The integrity
of the repair was assessed using ultrasound. Re-tear was detected
in 20 of 62 patients (32%) assessed with ultrasound. Age at operation We conclude that arthroscopic rotator cuff repair in patients
aged ≥ 70 years is a successful procedure. The gender and age of
the patient are important factors to consider when planning management. Cite this article:
Bone loss involving articular surface is a challenging
problem faced by the orthopaedic surgeon. In the hand and wrist,
there are articular defects that are amenable to autograft reconstruction
when primary fixation is not possible. In this article, the surgical
techniques and clinical outcomes of articular reconstructions in
the hand and wrist using non-vascularised osteochondral autografts
are reviewed.
This study evaluates the position of the long
head of biceps tendon using ultrasound following simple tenotomy,
in patients with arthroscopically repaired rotator cuff tears. In total, 52 patients with a mean age of 60.7 years (45 to 75)
underwent arthroscopic repair of the rotator cuff and simple tenotomy
of the long head of biceps tendon. At two years post-operatively,
ultrasound revealed that the tendon was inside the bicipital groove
in 43 patients (82.7%) and outside in nine (17.3%); in six of these
it was lying just outside the groove and in the remaining three
(5.8%) it was in a remote position with a positive Popeye Sign.
A dynamic ultrasound scan revealed that the tenotomised tendons
had adhered to the surrounding tissues (autotenodesis).The initial
condition of the tendon influenced its final position (p <
0.0005).
The presence of a Popeye sign was statistically influenced by the
pre-operative co-existence of supraspinatus and subscapularis tears (p
<
0.0001). It appears that the natural history of the tenotomised long head
of biceps tendon is to tenodese itself inside or just outside the
bicipital groove, while its pre-operative condition and coexistent
subscapularis tears play a significant role in the occurrence of
a Popeye sign.
We systematically reviewed all the evidence published
in the English language on proximal interphalangeal joint (PIPJ)
replacement, to determine its effectiveness on the function of the
hand and the associated post-operative complications. Original studies were selected if they reported clinical outcome
with a minimum of one year’s follow-up. Quality was assessed using
the Cowley systematic review criteria modified for finger-joint
replacements. Of 319 articles identified, only five were adequately
reported according to our quality criteria; there were no randomised
controlled trials. PIPJ replacements had a substantial effect size
on hand pain of -23.2 (95% confidence interval (CI) -27.3 to -19.1)
and grip strength 1.2 (95% CI -10.7 to 13.1), and a small effect
on range of movement 0.2 (95% CI -0.4 to 0.8). A dorsal approach
was most successful. Post-operative loosening occurred in 10% (95%
CI 3 to 30) of ceramic and 12.5% (95% CI 7 to 21) of pyrocarbon
replacements. Post-operative complications occurred in 27.8% (95%
CI 20 to 37). We conclude that the effectiveness of PIPJ replacement has not
been established. Small observational case studies and short-term
follow-up, together with insufficient reporting of patient data,
functional outcomes and complications, limit the value of current
evidence. We recommend that a defined core set of patients, surgical and
outcome data for this intervention be routinely and systematically
collected within the framework of a joint registry.
Injectable collagenase is an alternative to surgical
treatment for Dupuytren’s disease. Previous studies have reported
on the effectiveness of collagenase in finger contractures. This
prospective study reports on the short-term safety and efficacy
of collagenase treatment in five thumb and first web space Dupuytren’s
contractures. The thumb and first web space contractures were treated
with injectable collagenase in four consecutive patients (five hands) with
experience of previous surgical digital fasciectomy. The thumb contracture
was measured by angle and span in two planes of thumb extension
and abduction before injection and after manipulation. Collagenase
treatment resulted in release of the contracture with a mean increase
in thumb to index angle from 23° (10° to 35°) to 56° (45° to 60°)
in extension and from 30° (10° to 50°) to 58° (50° to 65°) in abduction
and a mean increase in span from 1.9 cm (1 to 3.5) to 3.9 cm (3
to 5) in extension and from 2.4 cm (1.5 to 3.5) to 3.9 cm (3 to
4.5) in abduction. All patients reported an increased range of movement
and function and described collagenase therapy as preferable to
surgery. In the short-term collagenase is an effective, well-tolerated
and safe alternative to surgery for Dupuytren’s disease of the thumb.
The aim of this study was to determine whether there is any significant
difference in temporal measurements of pain, function and rates
of re-tear for arthroscopic rotator cuff repair (RCR) patients compared
with those patients undergoing open RCR. This study compared questionnaire- and clinical examination-based
outcomes over two years or longer for two series of patients who
met the inclusion criteria: 200 open RCR and 200 arthroscopic RCR
patients. All surgery was performed by a single surgeon. Objectives
Methods
A total of 12 epileptic patients (14 shoulders)
with recurrent seizures and anterior dislocations of the shoulder underwent
a Latarjet procedure and were reviewed at a mean of 8.3 years (1
to 20) post-operatively. Mean forward flexion decreased from 165° (100° to 180°)
to 160° (90° to 180°) (p = 0.5) and mean external rotation from 54° (10° to 90°)
to 43° (5° to 75°) (p = 0.058). The mean Rowe score was 76 (35 to
100) at the final follow-up. Radiologically, all shoulders showed
a glenoid-rim defect and Hill-Sachs lesions pre-operatively. Osteo-arthritic changes
of the glenohumeral joint were observed in five shoulders (36%)
pre-operatively and in eight shoulders (57%) post-operatively.
Re-dislocation during a seizure occurred in six shoulders (43%).
Five of these patients underwent revision surgery using a bone buttress
from the iliac crest and two of these patients re-dislocated due
to a new seizure. Due to the unacceptably high rate of re-dislocation after surgery
in these patients, the most important means of reducing the incidence
of further dislocation is the medical management of the seizures.
The Latarjet procedure should be reserved for the well-controlled
patient with epilepsy who has recurrent anterior dislocation of
the shoulder during activities of daily living.
