The aim of this study was to assess hypertrophy of the extra-articular
tendon of the long head of biceps (LHB) in patients with a rotator
cuff tear. The study involved 638 shoulders in 334 patients (175 men, 159
women, mean age 62.6 years; 25 to 81) with unilateral symptomatic
rotator cuff tears. The cross-sectional area (CSA) of the LHB tendon
in the bicipital groove was measured pre-operatively in both shoulders
using ultrasound. There were 154 asymptomatic rotator cuff tears
in the contralateral shoulder. Comparisons were made between those
with a symptomatic tear, an asymptomatic tear and those with no
rotator cuff tear. In the affected shoulders, the CSAs were compared
in relation to the location and size of the rotator cuff tear. Aims
Patients and Methods
Joint-preserving surgery of the hip (JPSH) has evolved considerably
and now includes a number of procedures, including arthroscopy,
surgical dislocation, and redirectional osteotomies of the femur
and acetabulum. There are a number of different factors which lead
to failure of JPSH. Consequently, it is of interest to assess the
various modes of failure in order to continue to identify best practice
and the indications for these procedures. Using a retrospective observational study design, we reviewed
1013 patients who had undergone JPSH by a single surgeon between
2005 and 2015. There were 509 men and 504 women with a mean age
of 39 years (16 to 78). Of the 1013 operations, 783 were arthroscopies,
122 surgical dislocations, and 108 peri-acetabular osteotomies (PAO).
We analysed the overall failure rates and modes of failure. Re-operations
were categorised into four groups: Mode 1 was arthritis progression
or organ failure leading to total hip arthroplasty (THA); Mode 2
was an Incorrect diagnosis/procedure; Mode 3 resulted from malcorrection
of femur (type A), acetabulum (type B), or labrum (type C) and Mode 4
resulted from an unintended consequence of the initial surgical
intervention.Aims

The aim of this systematic literature review was to assess the clinical level of evidence of commercially available demineralised bone matrix (DBM) products for their use in trauma and orthopaedic related surgery. A total of 17 DBM products were used as search terms in two available databases: Embase and PubMed according to the Preferred Reporting Items for Systematic Reviews and Meta Analyses statement. All articles that reported the clinical use of a DBM-product in trauma and orthopaedic related surgery were included.Objectives
Methods
We investigated whether blood metal ion levels could effectively
identify patients with bilateral Birmingham Hip Resurfacing (BHR)
implants who have adverse reactions to metal debris (ARMD). Metal ion levels in whole blood were measured in 185 patients
with bilateral BHRs. Patients were divided into those with ARMD
who either had undergone a revision for ARMD or had ARMD on imaging
(n = 30), and those without ARMD (n = 155). Receiver operating characteristic
analysis was used to determine the optimal thresholds of blood metal
ion levels for identifying patients with ARMD.Aims
Patients and Methods
This study describes the use of the Masquelet technique to treat
segmental tibial bone loss in 12 patients. This retrospective case series reviewed 12 patients treated between
2010 and 2015 to determine their clinical outcome. Patients were
mostly male with a mean age of 36 years (16 to 62). The outcomes
recorded included union, infection and amputation. The mean follow-up
was 675 days (403 to 952). Aims
Patients and Methods
This study aimed to characterise and qualitatively grade the severity of the corrosion particles released into the hip joint following taper corrosion. The 26 cases examined were CoC/ABG Modular (n = 13) and ASR/SROM (n = 13). Blood serum metal ion levels were collected before and after revision surgery. The haematoxylin and eosin tissue sections were graded on the presence of fibrin exudates, necrosis, inflammatory cells and corrosion products. The corrosion products were identified based on visible observation and graded on abundance. Two independent observers blinded to the clinical patient findings scored all cases. Elemental analysis was performed on corrosion products within tissue sections. X-Ray diffraction was used to identify crystalline structures present in taper debris.Objectives
Methods
To determine the effect of a change in design of a cementless
ceramic acetabular component in fixation and clinical outcome after
total hip arthroplasty We compared 342 hips (302 patients) operated between 1999 and
2005 with a relatively smooth hydroxyapatite coated acetabular component
(group 1), and 337 hips (310 patients) operated between 2006 and
2011 using a similar acetabular component with a macrotexture on
the entire outer surface of the component (group 2). The mean age of
the patients was 53.5 (14 to 70) in group 1 and 53.0 (15 to 70)
in group 2. The mean follow-up was 12.7 years (10 to 17) for group
1 and 7.2 years (4 to 10) for group 2.Aims
Patients and Methods
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:
Valgus knee deformity can present a number of
unique surgical challenges for the total knee arthroplasty (TKA)
surgeon. Understanding the typical patterns of bone and soft-tissue pathology
in the valgus arthritic knee is critical for appropriate surgical
planning. This review aims to provide the knee arthroplasty surgeon
with an understanding of surgical management strategies for the
treatment of valgus knee arthritis. Lateral femoral and tibial deficiencies, contracted lateral soft
tissues, attenuated medial soft tissues, and multiplanar deformities
may all be present in the valgus arthritic knee. A number of classifications
have been reported in order to guide surgical management, and a variety
of surgical strategies have been described with satisfactory clinical
results. Depending on the severity of the deformity, a variety of
TKA implant designs may be appropriate for use. Regardless of an operating surgeon’s preferred surgical strategy,
adherence to a step-wise approach to deformity correction is advised. Cite this article:
The use of ceramic femoral heads in total hip arthroplasty (THA) has increased due to their proven low bearing wear characteristics. Ceramic femoral heads are also thought to reduce wear and corrosion at the head-stem junction with titanium (Ti) stems when compared with metal heads. We sought to evaluate taper damage of ceramic compared with metal heads when paired with cobalt chromium (CoCr) alloy stems in a single stem design. This retrieval study involved 48 total hip arthroplasties (THAs) with CoCr V40 trunnions paired with either CoCr (n = 21) or ceramic (n = 27) heads. The taper junction of all hips was evaluated for fretting/corrosion damage and volumetric material loss using a roundness-measuring machine. We used linear regression analysis to investigate taper damage differences after adjusting for potential confounding variables.Objectives
Methods
This is the first prospective study to report the pre- and post-operative
patient reported outcomes and satisfaction scores following excision
of interdigital Morton’s neuroma. Between May 2006 and April 2013, we prospectively studied 99
consecutive patients (111 feet) who were to undergo excision of
a Morton’s neuroma. There were 78 women and 21 men with a mean age
at the time of surgery of 56 years (22 to 78). Patients completed
the Manchester-Oxford Foot Questionnaire (MOXFQ), Short Form-12
(SF-12) and a supplementary patient satisfaction survey three months
pre-operatively and six months post-operatively.Aims
Patients and Methods
Total hip arthroplasty (THA) has well known subjective benefits,
but little is known objectively about the recovery of mobility in
the early post-operative period. A total of 33 patients aged >
60 years who underwent elective
primary THA had their activity monitored for 30 days post-operatively
using an at-home (Fitbit) ankle accelerometer. Their mean age was
70.7 years (61 to 86); 15 (45.5%) were female. The rate of compliance
and the mean level of activity were determined. Comparisons between subgroups
based on age, body mass index (BMI), surgical approach, and the
destination of the patients when discharged were also performed.Aims
Patients and Methods
The aim of this paper is to review the evidence relating to the
anatomy of the proximal femur, the geometry of the fracture and
the characteristics of implants and methods of fixation of intertrochanteric
fractures of the hip. Relevant papers were identified from appropriate clinical databases
and a narrative review was undertaken.Aims
