The free latissimus dorsi muscle (LDM) flap represents a workhorse procedure in the field of trauma and plastic surgery. However, only a small number of studies have examined this large group of patients with regard to the morbidity of flap harvest. The aim of this prospective study was therefore to objectively investigate the morbidity of a free LDM flap. A control group (n = 100) without surgery was recruited to assess the differences in strength and range of motion (ROM) in the shoulder joint with regard to handedness of patients. Additionally, in 40 patients with free LDM flap surgery, these parameters were assessed in an identical manner.Aims
Methods
The aim of the present study was to assess the outcomes of the induced membrane technique (IMT) for the management of infected segmental bone defects, and to analyze predictive factors associated with unfavourable outcomes. Between May 2012 and December 2020, 203 patients with infected segmental bone defects treated with the IMT were enrolled. The digital medical records of these patients were retrospectively analyzed. Factors associated with unfavourable outcomes were identified through logistic regression analysis.Aims

Ankle fractures are common injuries and the third most common fragility fracture. In all, 40% of ankle fractures in the frail are open and represent a complex clinical scenario, with morbidity and mortality rates similar to hip fracture patients. They have a higher risk of complications, such as wound infections, malunion, hospital-acquired infections, pressure sores, veno-thromboembolic events, and significant sarcopaenia from prolonged bed rest. A modified Delphi method was used and a group of experts with a vested interest in best practice were invited from the British Foot and Ankle Society (BOFAS), British Orthopaedic Association (BOA), Orthopaedic Trauma Society (OTS), British Association of Plastic & Reconstructive Surgeons (BAPRAS), British Geriatric Society (BGS), and the British Limb Reconstruction Society (BLRS).Aims
Methods
Acetabular fractures are associated with long-term morbidity. Our prospective cohort study sought to understand the recovery trajectory of this injury over five years. Eligible patients at a level I trauma centre were recruited into a longitudinal registry of surgical acetabular fractures between June 2004 and August 2019. Patient-reported outcome measures (PROMs), including the 36-Item Short Form Health Survey (SF-36) physical component summary (PCS), were recorded at baseline pre-injury recall and six months, one year, two years, and five years postoperatively. Comparative analyses were performed for elementary and associated fracture patterns. The proportion of patients achieving minimal clinically important difference (MCID) was determined. The rate of, and time to, conversion to total hip arthroplasty (THA) was also established.Aims
Methods
Monocyte-lymphocyte ratio (MLR) or neutrophil-lymphocyte ratio (NLR) are useful for diagnosing periprosthetic joint infection (PJI), but their diagnostic values are unclear for screening fixation-related infection (FRI) in patients for whom conversion total hip arthroplasty (THA) is planned after failed internal fixation for femoral neck fracture. We retrospectively included 340 patients who underwent conversion THA after internal fixation for femoral neck fracture from January 2008 to September 2020. Those patients constituted two groups: noninfected patients and patients diagnosed with FRI according to the 2013 International Consensus Meeting Criteria. Receiver operating characteristic (ROC) curves were used to determine maximum sensitivity and specificity of these two preoperative ratios. The diagnostic performance of the two ratios combined with preoperative CRP or ESR was also evaluated.Aims
Methods
To compare the functionality of adults with displaced mid-shaft clavicular fractures treated either operatively or nonoperatively and to compare the relative risk of nonunion and reoperation between the two groups. Based on specific eligibility criteria, 120 adults (median age 37.5 years (interquartile range (18 to 61)) and 84% males (n = 101)) diagnosed with an acute displaced mid-shaft fracture were recruited, and randomized to either the operative (n = 60) or nonoperative (n = 60) treatment group. This randomized controlled, partially blinded trial followed patients for 12 months following initial treatment. Functionality was assessed by the Constant score (CS) (assessor blinded to treatment) and Disability of the Arm, Shoulder and Hand (DASH) score. Clinical and radiological evaluation, and review of patient files for complications and reoperations, were added as secondary outcomes.Aims
Methods
There is a lack of long-term data for minimally invasive acromioclavicular (AC) joint repair. Furthermore, it is not clear if good early clinical results can be maintained over time. The purpose of this study was to report long-term results of minimally invasive AC joint reconstruction (MINAR) and compare it to corresponding short-term data. We assessed patients with a follow-up of at least five years after minimally invasive flip-button repair for high-grade AC joint dislocation. The clinical outcome was evaluated using the Constant score and a questionnaire. Ultrasound determined the coracoclavicular (CC) distance. Results of the current follow-up were compared to the short-term results of the same cohort.Aims

The primary aim of this study was to establish the cost-effectiveness of the early fixation of displaced midshaft clavicle fractures. A cost analysis was conducted within a randomized controlled trial comparing conservative management (n = 92) Aims
Patients and Methods
Displaced, comminuted acetabular fractures in the elderly are increasingly common, but there is no consensus on whether they should be treated non-surgically, surgically with open reduction and internal fixation (ORIF), or with acute total hip arthroplasty (THA). A combination of ORIF and acute THA, an approach called ’combined hip procedure’ (CHP), has been advocated and our aim was to compare the outcome after CHP or ORIF alone. A total of 27 patients with similar acetabular fractures (severe acetabular impaction with or without concomitant femoral head injury) with a mean age of 72.2 years (50 to 89) were prospectively followed for a minimum of two years. In all, 14 were treated with ORIF alone and 13 were treated with a CHP. Hip joint and patient survival were estimated. Operating times, blood loss, radiological outcomes, and patient-reported outcomes were assessed.Aims
Patients and Methods
Many authors have reported a shorter treatment time when using trifocal bone transport (TFT) rather than bifocal bone transport (BFT) in the management of long segmental tibial bone defects. However, the difference in the incidence of additional procedures, the true complications, and the final results have not been investigated. A total of 86 consecutive patients with a long tibial bone defect (≥ 8 cm), who were treated between January 2008 and January 2015, were retrospectively reviewed. A total of 45 were treated by BFT and 41 by TFT. The median age of the 45 patients in the BFT group was 43 years (interquartile range (IQR) 23 to 54).Aims

The Intraosseous Transcutaneous Amputation Prosthesis (ITAP)
may improve quality of life for amputees by avoiding soft-tissue
complications associated with socket prostheses and by improving
sensory feedback and function. It relies on the formation of a seal
between the soft tissues and the implant and currently has a flange
with drilled holes to promote dermal attachment. Despite this, infection
remains a significant risk. This study explored alternative strategies
to enhance soft-tissue integration. The effect of ITAP pins with a fully porous titanium alloy flange
with interconnected pores on soft-tissue integration was investigated.
The flanges were coated with fibronectin-functionalised hydroxyapatite
and silver coatings, which have been shown to have an antibacterial
effect, while also promoting viable fibroblast growth Aims

This is a prospective randomised study which compares the radiological
and functional outcomes of ring and rail fixators in patients with
an infected gap (>
3 cm) nonunion of the tibia. Between May 2008 and February 2013, 70 patients were treated
at our Institute for a posttraumatic osseocutaneous defect of the
tibia measuring at least 3 cm. These were randomised into two groups
of 35 patients using the lottery method. Group I patients were treated
with a ring fixator and group II patients with a rail fixator. The
mean age was 33.2 years (18 to 64) in group I and 29.3 years (18
to 65) in group II. The mean bone gap was 5.84 cm in group I and 5.78
cm in group II. The mean followup was 33.8 months in group I and 32.6 months
in group II. Bone and functional results were assessed using the
classification of the Association for the Study and Application
of the Method of Ilizarov (ASAMI). Functional results were also
assessed at six months using the short musculoskeletal functional
assessment (SMFA) score.Aims
Patients and Methods
Objectives. Deep bone and joint infections (DBJI) are directly intertwined with health, demographic change towards an elderly population, and wellbeing. The elderly human population is more prone to acquire infections, and the consequences such as pain, reduced quality of life, morbidity, absence from work and premature retirement due to disability place significant burdens on already strained healthcare systems and societal budgets. DBJIs are less responsive to systemic antibiotics because of poor vascular perfusion in necrotic bone, large bone defects and persistent biofilm-based infection. Emerging bacterial resistance poses a major threat and new innovative treatment modalities are urgently needed to curb its current trajectory. Materials and Methods. We present a new biphasic ceramic bone substitute consisting of hydroxyapatite and calcium sulphate for local antibiotic delivery in combination with bone regeneration. Gentamicin release was measured in four setups: 1) in vitro elution in Ringer’s solution; 2) local elution in patients treated for trochanteric hip fractures or uncemented hip revisions; 3) local elution in patients treated with a bone tumour
Demineralised bone matrix (DBM) is rarely used for the local
delivery of prophylactic antibiotics. Our aim, in this study, was
to show that a graft with a bioactive glass and DBM combination,
which is currently available for clinical use, can be loaded with
tobramycin and release levels of antibiotic greater than the minimum
inhibitory concentration for Antibiotic was loaded into a graft and subsequently evaluated
for drug elution kinetics and the inhibition of bacterial growth.
A rat femoral condylar plug model was used to determine the effect
of the graft, loaded with antibiotic, on bone healing.Aims

While use of large national clinical databases for orthopaedic
trauma research has increased dramatically, there has been little
study of the differences in populations contained therein. In this
study we aimed to compare populations of patients with femoral shaft
fractures across three commonly used national databases, specifically
with regard to age and comorbidities. Patients were identified in the Nationwide Inpatient Sample (NIS),
National Surgical Quality Improvement Program (NSQIP) and National
Trauma Data Bank (NTDB). Aims
Patients and Methods
Tibial nonunion represents a spectrum of conditions
which are challenging to treat, and optimal management remains unclear
despite its high rate of incidence. We present 44 consecutive patients
with 46 stiff tibial nonunions, treated with hexapod external fixators
and distraction to achieve union and gradual deformity correction.
There were 31 men and 13 women with a mean age of 35 years (18 to
68) and a mean follow-up of 12 months (6 to 40). No tibial osteotomies
or bone graft procedures were performed. Bony union was achieved
after the initial surgery in 41 (89.1%) tibias. Four persistent
nonunions united after repeat treatment with closed hexapod distraction,
resulting in bony union in 45 (97.8%) patients. The mean time to
union was 23 weeks (11 to 49). Leg-length was restored to within
1 cm of the contralateral side in all tibias. Mechanical alignment
was restored to within 5° of normal in 42 (91.3%) tibias. Closed
distraction of stiff tibial nonunions can predictably lead to union
without further surgery or bone graft. In addition to generating
the required distraction to achieve union, hexapod circular external
fixators can accurately correct concurrent deformities and limb-length
discrepancies. Cite this article:
The Essex-Lopresti injury (ELI) of the forearm
is a rare and serious condition which is often overlooked, leading
to a poor outcome. The purpose of this retrospective case study was to establish
whether early surgery can give good medium-term results. From a group of 295 patients with a fracture of the radial head,
12 patients were diagnosed with ELI on MRI which confirmed injury
to the interosseous membrane (IOM) and ligament (IOL). They were
treated by reduction and temporary Kirschner (K)-wire stabilisation
of the distal radioulnar joint (DRUJ). In addition, eight patients
had a radial head replacement, and two a radial head reconstruction. All patients were examined clinically and radiologically 59 months
(25 to 90) after surgery when the mean Mayo Modified Wrist Score
(MMWS) was 88.4 (78 to 94), the mean Mayo Elbow Performance Scores
(MEPS) 86.7 (77 to 95) and the mean disabilities of arm, shoulder
and hand (DASH) score 20.5 (16 to 31): all of these indicate a good outcome. In case of a high index of suspicion for ELI in patients with
a radial head fracture, we recommend the following: confirmation
of IOM and IOL injury with an early MRI scan; early surgery with
reduction and temporary K-wire stabilisation of the DRUJ; preservation
of the radial head if at all possible or replacement if not, and
functional bracing in supination. This will increase the prospect
of a good result, and avoid the complications of a missed diagnosis
and the difficulties of late treatment. Cite this article:
It is becoming increasingly common for a patient
to have ipsilateral hip and knee replacements. The inter-prosthetic (IP)
distance, the distance between the tips of hip and knee prostheses,
has been thought to be associated with an increased risk of IP fracture.
Small gap distances are generally assumed to act as stress risers,
although there is no real biomechanical evidence to support this. The purpose of this study was to evaluate the influence of IP
distance, cortical thickness and bone mineral density on the likelihood
of an IP femoral fracture. A total of 18 human femur specimens were randomised into three
groups by bone density and cortical thickness. For each group, a
defined IP distance of 35 mm, 80 mm or 160 mm was created by choosing
the appropriate lengths of component. The maximum fracture strength
was determined using a four-point bending test. The fracture force of all three groups was similar (p = 0.498).
There was a highly significant correlation between the cortical
area and the fracture strength (r = 0.804, p <
0.001), whereas
bone density showed no influence. This study suggests that the IP distance has little influence
on fracture strength in IP femoral fractures: the thickness of the
cortex seems to be the decisive factor. Cite this article:
In order to achieve satisfactory reduction of
complex distal humeral fractures, adequate exposure of the fracture fragments
and the joint surface is required. Several surgical exposures have
been described for distal humeral fractures. We report our experience
using the anconeus pedicle olecranon flip osteotomy approach. This
involves detachment of the triceps along with a sliver of olecranon,
which retains the anconeus pedicle. We report the use of this approach
in ten patients (six male, four female) with a mean age of 38.4
years (28 to 51). The mean follow-up was 15 months (12 to 18) with
no loss to follow-up. Elbow function was graded using the Mayo Score.
The results were excellent in four patients, good in five and fair
in one patient. The mean time to both fracture and osteotomy union
was 10.6 weeks (8 to 12) and 7.1 weeks (6 to 8), respectively. We
found this approach gave reliably good exposure for these difficult
fractures enabling anatomical reduction and bicondylar plating without
complications. Cite this article:
Gunshot injuries to the shoulder are rare and
difficult to manage. We present a case series of seven patients
who sustained a severe shoulder injury to the non-dominant side
as a result of a self-inflicted gunshot wound. We describe the injury
as ‘suicide shoulder’ caused by upward and outward movement of the
gun barrel as the trigger is pulled. All patients were male, with
a mean age of 32 years (21 to 48). All were treated at the time
of injury with initial repeated debridement, and within four weeks
either by hemiarthroplasty (four patients) or arthrodesis (three patients).
The hemiarthroplasty failed in one patient after 20 years due to
infection and an arthrodesis was attempted, which also failed due
to infection. Overall follow-up was for a mean of 26 months (12
to 44). All four hemiarthroplasty implants were removed with no
feasible reconstruction ultimately possible, resulting in a poor functional
outcome and no return to work. In contrast, all three primary arthrodeses
eventually united, with two patients requiring revision plating
and grafting. These patients returned to work with a good functional
outcome. We recommend arthrodesis rather than replacement as the
treatment of choice for this challenging injury. Cite this article:
