The purpose of this study was to determine whether there were long-term differences in outcomes of reverse shoulder arthroplasty (RSA) undertaken for acute proximal humeral fracture versus rotator cuff deficiency with a minimum follow-up of five years. This was a prospective cohort study comparing 67 patients with acute complex proximal humeral fracture and 64 patients with irreparable rotator cuff deficiency who underwent primary RSA. In the fracture group, there were 52 (77.6%) females and 15 (22.4%) males, with a mean age of 73.5 years (51 to 85), while in the arthropathy group, there were 43 (67.1%) females and 21 (32.9%) males, with a mean age of 70.6 years (50 to 84). Patients were assessed by the Constant score, University of California Los Angeles shoulder score (UCLA), short version of the Disability of the Arm Shoulder and Hand score (QuickDASH), and visual analogue scales (VAS) for pain and satisfaction. Radiological evaluation was also performed.Aims

Pelvic discontinuity represents a rare but challenging
problem for orthopaedic surgeons. It is most commonly encountered
during revision total hip replacement, but can also result from
an iatrogentic acetabular fracture during hip replacement. The general
principles in management of pelvic discontinuity include restoration
of the continuity between the ilium and the ischium, typically with
some form of plating. Bone grafting is frequently required to restore
pelvic bone stock. The acetabular component is then impacted, typically
using an uncemented, trabecular metal component. Fixation with multiple
supplemental screws is performed. For larger defects, a so-called
‘cup–cage’
This study presents patient-reported quality of life (QoL) over the first year following surgical debridement of long bone osteomyelitis. It assesses the bone involvement, antimicrobial options, coverage of soft tissues, and host status (BACH) classification as a prognostic tool and its ability to stratify cases into ‘uncomplicated’ or ‘complex’. Patients with long-bone osteomyelitis were identified prospectively between June 2010 and October 2015. All patients underwent surgical debridement in a single-staged procedure at a specialist bone infection unit. Self-reported QoL was assessed prospectively using the three-level EuroQol five-dimension questionnaire (EQ-5D-3L) index score and visual analogue scale (EQ-VAS) at five postoperative time-points (baseline, 14 days, 42 days, 120 days, and 365 days). BACH classification was applied retrospectively by two clinicians blinded to outcome.Aims
Methods
To describe a new objective classification for open fractures of the lower limb and to correlate the classification with patient-centred outcomes. The proposed classification was investigated within a cohort of adults with open fractures of the lower limb who were recruited as part of two large clinical trials within the UK Major Trauma Network. The classification was correlated with patient-reported Disability Rating Index (DRI) and EuroQol five-dimension questionnaire (EQ-5D) health-related quality of life in the year after injury, and with deep infection at 30 days, according to the Centers for Disease Control and Prevention definition of a deep surgical site infection.Aims
Methods
A pelvic discontinuity occurs when the superior
and inferior parts of the hemi-pelvis are no longer connected, which
is difficult to manage when associated with a failed total hip replacement.
Chronic pelvic discontinuity is found in 0.9% to 2.1% of hip revision
cases with risk factors including severe pelvic bone loss, female
gender, prior pelvic radiation and rheumatoid arthritis. Common
treatment options include: pelvic plating with allograft, cage

The aim of this study was to evaluate the need for hand trauma services during the COVID-19 pandemic lockdown, specifically related to surgical requirements. This will provide useful information for planning and resource allocation in the event of any further lockdown. A prospective analsysis of all patients attending our hand trauma unit throughout the UK COVID-19 lockdown period (24 March to 10 May 2020) was carried out. Prospectively collected departmental data from the same period in 2019 was obtained and reviewed for comparison. The number of patients attending clinic, undergoing surgery, the type of surgical procedure, and rate of surgery was compared.Aims
Methods
To compare results of institutional preferences with regard to treatment of soft tissues in the setting of open tibial shaft fractures. We present a retrospective review of open tibial shaft fractures at two high-volume level 1 trauma centres with differing practices with regard to the acute management of soft tissues. Site 1 attempts acute primary closure, while site 2 prefers delayed closure/coverage. Comparisons include percentage of primary closure, number of surgical procedures until definitive closure, percentage requiring soft tissue coverage, and percentage of 90-day wound complication.Aims

Osteoarthritis (OA) is a disabling joint disorder and mechanical loading is an important pathogenesis. This study aims to investigate the benefits of less mechanical loading created by intermittent tail suspension for knee OA. A post-traumatic OA model was established in 20 rats (12 weeks old, male). Ten rats were treated with less mechanical loading through intermittent tail suspension, while another ten rats were treated with normal mechanical loading. Cartilage damage was determined by gross appearance, Safranin O/Fast Green staining, and immunohistochemistry examinations. Subchondral bone changes were analyzed by micro-CT and tartrate-resistant acid phosphatase (TRAP) staining, and serum inflammatory cytokines were evaluated by enzyme-linked immunosorbent assay (ELISA).Aims

The integrity of the soft tissue envelope is crucial for successful treatment of infected total knee arthroplasty (TKA). The purpose of this study was to evaluate the rate of limb salvage, infection control, and clinical function following microvascular free flap coverage for salvage of the infected TKA. We retrospectively reviewed 23 microvascular free tissue transfers for management of soft tissue defects in infected TKA. There were 16 men and seven women with a mean age of 61.2 years (39 to 81). The median number of procedures performed prior to soft tissue coverage was five (2 to 9) and all patients had failed at least one two-stage reimplantation procedure. Clinical outcomes were measured using the Knee Society Scoring system for pain and function.Aims

We investigated the detailed anatomy of the gluteus
maximus, gluteus medius and gluteus minimus and their neurovascular
supply in 22 hips in 11 embalmed adult Caucasian human cadavers.
This led to the development of a surgical technique for an extended
posterior approach to the hip and pelvis that exposes the supra-acetabular
ilium and preserves the glutei during revision hip surgery. Proximal
to distal mobilisation of the gluteus medius from the posterior
gluteal line permits exposure and mobilisation of the superior gluteal
neurovascular bundle between the sciatic notch and the entrance
to the gluteus medius, enabling a wider exposure of the supra-acetabular
ilium. This technique was subsequently used in nine patients undergoing
revision total hip replacement involving the
The understanding of rotational alignment of the distal femur is essential in total knee replacement to ensure that there is correct placement of the femoral component. Many reference axes have been described, but there is still disagreement about their value and mutual angular relationship. Our aim was to validate a geometrically-defined reference axis against which the surface-derived axes could be compared in the axial plane. A total of 12 cadaver specimens underwent CT after rigid fixation of optical tracking devices to the femur and the tibia. Three-dimensional
In this retrospective study, we investigated
the results of revision total hip replacement (THR) using a cemented long-stemmed
Exeter femoral component, with a minimum length of 205 mm in patients
with extensive femoral bone defects. The study included 37 consecutive
patients with a mean age of 76 years (39 to 93) and a mean follow-up
of nine years (5 to 16). A total of 26 patients (70%) had a pre-operative
Endo-Klinik score of 3 or 4. Impaction bone grafting was used in
24 patients (65%). At the time of evaluation, 22 patients (59%)
were still alive and were evaluated clinically and radiologically.
A total of 14 patients died during follow-up and their data were
included until the time of their death. One
Proliferation, migration, and differentiation of anterior cruciate ligament (ACL) remnant and surrounding cells are fundamental processes for ACL reconstruction; however, the interaction between ACL remnant and surrounding cells is unclear. We hypothesized that ACL remnant cells preserve the capability to regulate the surrounding cells’ activity, collagen gene expression, and tenogenic differentiation. Moreover, extracorporeal shock wave (ESW) would not only promote activity of ACL remnant cells, but also enhance their paracrine regulation of surrounding cells. Cell viability, proliferation, migration, and expression levels of Collagen-I (COL-I) A1, transforming growth factor beta (TGF-β), and vascular endothelial growth factor (VEGF) were compared between ACL remnant cells untreated and treated with ESW (0.15 mJ/mm2, 1,000 impulses, 4 Hz). To evaluate the subsequent effects on the surrounding cells, bone marrow stromal cells (BMSCs)’ viability, proliferation, migration, and levels of Type I Collagen, Type III Collagen, and tenogenic gene (Aims
Methods
Metaphyseal bone loss is common with revision
total knee replacement (RTKR). Using the Anderson Orthopaedic Research
Institute (AORI) classification, type 2-B and type 3 defects usually
require large metal blocks, bulk structural allograft or highly
porous metal cones. Tibial and femoral trabecular metal metaphyseal
cones are a unique solution for large bone defects. These cones
substitute for bone loss, improve metaphyseal fixation, help correct
malalignment, restore the joint line and may permit use of a shorter
stem. The technique for insertion involves sculpturing of the remaining
bone with a high speed burr and rasp, followed by press-fit of the
cone into the metaphysis. The fixation and osteoconductive properties
of the porous cone outer surface allow ingrowth and encourage long-term
biological fixation. The revision knee component is then cemented
into the porous cone inner surface, which provides superior fixation
compared with cementing into native but deficient metaphyseal bone.
The advantages of the cone compared with allograft include: technical
ease, biological fixation, no resorption, and possibly a lower risk
of infection. The disadvantages include: difficult extraction and
relatively short-term follow-up. Several studies using cones report
promising short-term results for the
