The management of a significant bony defect following excision
of a diaphyseal atrophic femoral nonunion remains a challenge. We
present the outcomes using a combined technique of acute femoral
shortening, stabilized with a long retrograde intramedullary nail,
accompanied by bifocal osteotomy compression and distraction osteogenesis with
a temporary monolateral fixator. Eight men and two women underwent the ‘rail and nail’ technique
between 2008 and 2016. Proximal locking of the nail and removal
of the external fixator was undertaken once the length of the femur
had been restored and prior to full consolidation of the regenerate.Aims

The aim of this study was to compare the outcomes of surgery
using growing rods in patients with severe A review of a multicentre EOS database identified 107 children
with severe EOS (major curve ≥ 90°) treated with growing rods before
the age of ten years with a minimum follow-up of two years and three
or more lengthening procedures. From the same database, 107 matched
controls with moderate EOS were identified.Aims

Nerve palsy is a well-described complication
following total hip arthroplasty, but is highly distressing and
disabling. A nerve palsy may cause difficulty with the post-operative
rehabilitation, and overall mobility of the patient. Nerve palsy
may result from compression and tension to the affected nerve(s)
during the course of the operation via surgical manipulation and
retractor placement, tension from limb lengthening or compression
from post-operative hematoma. In the literature, hip dysplasia,
lengthening of the leg, the use of an uncemented femoral component, and
female gender are associated with a greater risk of nerve palsy.
We examined our experience at a high-volume, tertiary care referral
centre, and found an overall incidence of 0.3% out of 39 056 primary
hip arthroplasties. Risk factors found to be associated with the
incidence of nerve palsy at our institution included the presence
of spinal stenosis or lumbar disc disease, age younger than 50,
and smoking. If a nerve palsy is diagnosed, imaging is mandatory
and surgical evacuation or compressive haematomas may be beneficial.
As palsies are slow to recover, supportive care such as bracing,
therapy, and reassurance are the mainstays of treatment. Cite this article:
Preserving growth following limb-salvage surgery of the upper
limb in children remains a challenge. Vascularized autografts may
provide rapid biological incorporation with the potential for growth
and longevity. In this study, we aimed to describe the outcomes
following proximal humeral reconstruction with a vascularized fibular
epiphyseal transfer in children with a primary sarcoma of bone.
We also aimed to quantify the hypertrophy of the graft and the annual
growth, and to determine the functional outcomes of the neoglenofibular
joint. We retrospectively analyzed 11 patients who underwent this procedure
for a primary bone tumour of the proximal humerus between 2004 and
2015. Six had Ewing’s sarcoma and five had osteosarcoma. Their mean
age at the time of surgery was five years (two to eight). The mean
follow-up was 5.2 years (1 to 12.2).Aims

‘Big data’ is a term for data sets that are so
large or complex that traditional data processing applications are
inadequate. Billions of dollars have been spent on attempts to build predictive
tools from large sets of poorly controlled healthcare metadata.
Companies often sell reports at a physician or facility level based
on various flawed data sources, and comparative websites of ‘publicly
reported data’ purport to educate the public. Physicians should
be aware of concerns and pitfalls seen in such data definitions,
data clarity, data relevance, data sources and data cleaning when
evaluating analytic reports from metadata in health care. Cite this article:
The aim of this study was to compare the biomechanical stability and clinical outcome of external fixator combined with limited internal fixation (EFLIF) and open reduction and internal fixation (ORIF) in treating Sanders type 2 calcaneal fractures. Two types of fixation systems were selected for finite element analysis and a dual cohort study. Two fixation systems were simulated to fix the fracture in a finite element model. The relative displacement and stress distribution were analysed and compared. A total of 71 consecutive patients with closed Sanders type 2 calcaneal fractures were enrolled and divided into two groups according to the treatment to which they chose: the EFLIF group and the ORIF group. The radiological and clinical outcomes were evaluated and compared.Objectives
Methods
The aim of this study was to compare the effectiveness of a femoral
nerve block and a periarticular infiltration in the management of
early post-operative pain after total knee arthroplasty (TKA). A pragmatic, single centre, two arm parallel group, patient blinded,
randomised controlled trial was undertaken. All patients due for
TKA were eligible. Exclusion criteria included contraindications
to the medications involved in the study and patients with a neurological
abnormality of the lower limb. Patients received either a femoral
nerve block with 75 mg of 0.25% levobupivacaine hydrochloride around
the nerve, or periarticular infiltration with 150 mg of 0.25% levobupivacaine
hydrochloride, 10 mg morphine sulphate, 30 mg ketorolac trometamol
and 0.25 mg of adrenaline all diluted with 0.9% saline to make a
volume of 150 ml.Aims

The Bereiter trochleoplasty has been used in our unit for 12
years to manage recurrent patellar instability in patients with
severe trochlea dysplasia. The aim of this study was to document
the outcome of a large consecutive cohort of patients who have undergone
this operation. Between June 2002 and August 2013, 214 consecutive trochleoplasties
were carried out in 185 patients. There were 133 women and 52 men
with a mean age of 21.3 years (14 to 38). All patients were offered
yearly clinical and radiological follow-up. They completed the following
patient reported outcome scores (PROMs): International Knee Documentation
Committee subjective scale, the Kujala score, the Western Ontario
and McMaster Universities Arthritis Index score and the short-form
(SF)-12. Aims

Knee joint distraction (KJD) is a relatively new, knee-joint
preserving procedure with the goal of delaying total knee arthroplasty
(TKA) in young and middle-aged patients. We present a randomised
controlled trial comparing the two. The 60 patients ≤ 65 years with end-stage knee osteoarthritis
were randomised to either KJD (n = 20) or TKA (n = 40). Outcomes
were assessed at baseline, three, six, nine, and 12 months. In the
KJD group, the joint space width (JSW) was radiologically assessed,
representing a surrogate marker of cartilage thickness.Aims
Patients and Methods
Compartment syndrome is a rare complication of total knee arthroplasty that requires early recognition and prompt decompression in order to prevent long-term disability. We have found only one previous case report in the literature. We present a series of seven cases from four hospitals and five surgeons. Six of the cases resulted in the loss of at least one compartment, and one resulted in amputation. Four of the cases resulted in legal action. We suggest that important risk factors contributing to the development of this condition include complex surgery, soft-tissue compromise, previous surgery, and possibly vascular disease. Delay in the diagnosis and hence delay in decompression was common in our series, and in five cases appeared to be related to the use of a postoperative epidural infusion for pain relief. The presence of associated neurological compromise may have also been a significant factor in the delay to diagnosis in two cases.
Spinal stenosis and disc herniation are the two
most frequent causes of lumbosacral nerve root compression. This
can result in muscle weakness and present with or without pain. The
difficulty when managing patients with these conditions is knowing
when surgery is better than non-operative treatment: the evidence
is controversial. Younger patients with a lesser degree of weakness
for a shorter period of time have been shown to respond better to surgical
treatment than older patients with greater weakness for longer.
However, they also constitute a group that fares better without
surgery. The main indication for surgical treatment in the management
of patients with lumbosacral nerve root compression should be pain
rather than weakness.
The purpose of this study was to assess the outcome
of 15 patients (mean age 13.6 years (7 to 25)) with a primary sarcoma
of the tibial diaphysis who had undergone excision of the affected
segment that was then irradiated (90 Gy) and reimplanted with an
ipsilateral vascularised fibular graft within it. The mean follow-up was 57 months (22 to 99). The mean time to
full weight-bearing was 23 weeks (9 to 57) and to complete radiological
union 42.1 weeks (33 to 55). Of the 15 patients, seven required
a further operation, four to obtain skin cover. The mean Musculoskeletal
Society Tumor Society functional score at final follow-up was 27
out of 30 once union was complete. The functional results were comparable
with those of allograft reconstruction and had a similar rate of
complication. We believe this to be a satisfactory method of biological reconstruction
of the tibial diaphysis in selected patients.
Controversy surrounds the most appropriate treatment
method for patients with a rupture of the tendo Achillis. The aim
of this study was to assess the long term rate of re-rupture following
management with a non-operative functional protocol. We report the outcome of 945 consecutive patients (949 tendons)
diagnosed with a rupture of the tendo Achillis managed between 1996
and 2008. There were 255 female and 690 male patients with a mean
age of 48.97 years (12 to 86). Delayed presentation was defined
as establishing the diagnosis and commencing treatment more than
two weeks after injury. The overall rate of re-rupture was 2.8%
(27 re-ruptures), with a rate of 2.9%
(25 re-ruptures) for those with an acute presentation and 2.7% (two
re-ruptures) for those with delayed presentation. This study of non-operative functional management of rupture
of the tendo Achillis is the largest of its kind in the literature. Our
rates of re-rupture are similar to, or better than, those published
for operative treatment. We recommend our regime for patients of
all ages and sporting demands, but it is essential that they adhere
to the protocol.
Injury to the sciatic nerve following closed manipulation of a dislocated total hip replacement is rare. We present such a case in an elderly patient with partial recovery following exploration and release of the nerve.
A 16-year-old professional female ballet student sustained a plantar flexion-inversion injury to her left ankle while dancing. Clinical examination and MRI suggested subluxation of the tibiotalar joint. However, accurate diagnosis was hampered by a transient palsy of the common peroneal nerve. It was subsequently established that she had also sustained a dislocation of her calcaneocuboid joint, a rare injury, which was successfully stabilised by using a hamstring graft. The presentation and management of this rare condition are discussed.
Popliteal artery injury (PAI) is a feared complication
during knee replacement. Our aim was to investigate those injuries
that occurred in association with knee replacement in terms of the
type of injury, treatment and outcomes. From our national vascular registry (Swedvasc) and the Swedish
Patient Insurance databases a total of 32 cases were identified.
Prospective data from the registries was supplemented with case-records,
including long-term follow-up. We estimated the incidence during 1998 to 2010 to be 0.017%.
In our series of 32 patients with PAI occurring between 1987 and
2011, 25 (78%) were due to penetrating trauma and seven were caused
by blunt trauma. The patients presented in three ways: bleeding
(14), ischaemia (7) and false aneurysm formation (11), and five
occurred during revision surgery. A total of 12 injuries were detected
intra-operatively, eight within 24 hours (3 to 24) and 12 at more
than 24 hours post-operatively (2 to 90 days). Treatment comprised
open surgery in 28 patients. Patency of the vascular repair at 30
days was 97% (31 of 32, one amputation). At the time of follow-up
(median 546 days, mean 677 days (24 to 1251)), 25 patients had residual
symptoms. Of seven patients with a complete recovery, six had had
an early diagnosis of the PAI during the procedure, and were treated
by a vascular surgeon in the same hospital. PAI is a rare adverse event during knee replacement surgery.
The outcome following such events is often adversely affected by
diagnostic and therapeutic delay. Bleeding and false aneurysm were
the most common clinical presentations. Cite this article:
