Introduction

The purpose of this study is to evaluate the radiological and clinical outcomes in Northern Ireland of free vascularised fibular bone grafting for the treatment of humeral bone loss secondary to osteomyelitis. Upper limb skeletal bone loss due to osteomyelitis is a devastating and challenging complication to manage for both surgeon and patient. Patients can be left with life altering disability and functional impairment. This limb threatening complication raises the question of salvage versus amputation and the associated risk and benefits of each. Free vascularised fibula grafting is a recognised treatment option for large skeletal defects in long bones but is not without significant risk. The benefit of vascularised over non-vascularised fibula grafts include preservation of blood supply lending itself to improved remodeling and osteointegration.

Introduction

Osteogenesis imperfect (OI) is a geno- and phenotypically heterogeneous group of congenital collagen disorders characterized by fragility and microfractures resulting in long bone deformities. OI can lead to progressive femoral coxa vara from bone and muscular imbalance and continuous microfracture about the proximal femur. If left untreated, patients develop Trendelenburg gait, leg length discrepancy, further stress fracture and acute fracture at the apex of the deformity, impingement and hip joint degeneration. In the OI patient, femoral coxa vara cannot be treated in isolation and consideration must be given to protecting the whole bone with the primary goal of verticalization and improved biomechanical stability to allow early loading, safe standing, re-orientation of the physis and avoidance of untreated sequelae. Implant constructs should therefore be designed to accommodate and protect the whole bone. The normal paediatric femoral neck shaft angle (FNSA) ranges from 135 to 145 degrees. In OI the progressive pathomechanical changes result in FNSA of significantly less than 120 degrees and decreased Hilgenreiner epiphyseal angles (HEA). Proximal femoral valgus osteotomy is considered the standard surgical treatment for coxa vara and multiple surgical techniques have been described, each with their associated complications. In this paper we present the novel technique of controlling femoral version and coronal alignment using a tubular plate and long bone protection with the use of teleoscoping rods.

Acetabular cup positioning remains a real challenge and component malpositioning after total hip arthroplasty (THA) can lead to increased rates of dislocation and wear. It is a common cause for revision THA. A novel 3D imageless mini-optical navigation system was used during THA to provide accurate, intraoperative, real-time, and non-fluoroscopic data including component positioning to the surgeon. This retrospective comparative single surgeon and single approach study examined acetabular component positioning between traditional mini-posterolateral THA and mini-posterolateral THA using the 3D mini-optical navigation system. A retrospective chart review was conducted of 157 consecutive (78 3D mini-optical navigation and 79 traditional non-navigation methods) THAs performed by the senior author using a mini-posterolateral approach at an ambulatory surgery center and hospital setting. Two independent reviewers analyzed postoperative radiographs in a standardized fashion to measure acetabular component positioning. Demographic, clinical, surgical, and radiographic data were analyzed.

These groups were found to have no statistical difference in age, gender, and BMI (Table I). There was no difference between groups in acetabular components in the Lewinnek safe zone, 31.2% vs 26.6% (p = 0.53). Cup anteversion within the safe zone did not differ, 35.1% vs 40.5% (p = 0.48); while cup inclination within the safe zone differed, with more in the navigation group, 77.9% vs 51.9% (p < 0.01). Change in leg length was significantly different with the navigation group's leg length at 1.9 ± 6.3, less than the traditional at 5.4 ± 7.0 (p < 0.01). There was no difference in mean change in offset between groups (4.5 ± 5.9 vs 6.2 ± 7.9, p = 0.12); navigation, traditional) (Table II). The 3D mini-optical navigation group did have significantly longer operative time (98.4 ± 17.5 vs 89.3 ± 15.5 p < 0.01). Use of the novel 3D Mini-optical Navigation System significantly improved cup inclination compared to traditional methods while increasing operative time.

Distension arthrography of the glenohumeral joint was adopted as a mainstream treatment for adhesive capsulitis before any randomised controlled trials were performed. Interpretation of the effectiveness of this procedure rests on data from cohort studies of which there are few of high quality. Papers reporting on the long-term results have either excluded diabetic patients or failed to report on patient orientated outcomes.

We present a prospective cohort study of 51 patients with adhesive capsulitis of the shoulder who had a distension arthrogram performed by a single radiologist as a primary intervention. We included diabetic patients.

Range of movement (ROM), Oxford shoulder score (OSS) and a visual analogue pain score (VAS) were recorded pre-procedure, at 2 days and 1 month. OSS and VAS were recorded again at a mean of 14 months post procedure (range 8–26 months).

OSS improved from pre-procedure mean of 22.3 by 16.9 points at final follow up in September 2011 (p < 0.001) whilst VAS improved from a mean pre-procedure of 7.1 by −3.5 by September 2011 (p< 0.001). ROM improved with a mean increase of 39.3 degrees in flexion, 55.2 degrees in abduction and 19.5 degrees in external rotation by 1 month (p < 0.001 for all). The outcome in diabetic patients was the same as in non-diabetic patients.

We conclude that distension arthrography is a safe and effective treatment for adhesive capsulitis.

The majority of proximal humerus fractures can be managed non-operatively with surgery reserved for approximately 10–20% of patients. The choice of surgical treatment is usually between a humeral head head-conserving fracture reduction and internal fixation and humeral head sacrifice hemiarthroplasty. Current indications for primary hemiarthroplasty include a displaced four-part fracture (with or without associated dislocation of the humeral head) and a head-splitting fracture (with involvement of >40% of the articular surface), due to the high associated risk of avascular necrosis. However, the indications for internal fixation of proximal humerus fractures have expanded over the last decade, and many fractures which have previously been considered unsalvageable and treated either non-operatively or with hemiarthroplasty are now deemed reconstructable. This is partially as a result of improved appreciation of sub-groups of fractures which have a better prognosis from head-salvage, the possibility that subsequent development of osteonecrosis may be relatively asymptomatic and the realisation that functional results after hemiarthroplasty are often sub-optimal.

The purpose of this talk is to discuss the current concepts in fracture classification and the indications for operative treatment for these fractures. The novel surgical approaches, techniques and implants which have renewed interest in their treatment are also highlighted.

The traditional view that the vast majority clavicle fractures heal with non- operative treatment with consistently good functional outcomes is no longer valid. Recent studies have identified a higher rate of nonunion and specific defects of shoulder function in sub-groups of patients with these injuries. These fractures should therefore be viewed as a spectrum of injuries with diverse functional outcomes, each requiring careful assessment and individualised treatment. This talk provides an overview of the current knowledge regarding their epidemiology, classification, clinical assessment and treatment in adults. The following key points will be highlighted:

Undisplaced fractures of both the diaphysis and the lateral end of the clavicle have a high rate of union and good functional outcomes after non-operative treatment.

Primary traumatic anterior dislocations of the glenohumeral joint in young adults are common injuries, which are associated with persistent deficits of shoulder function and a high risk of recurrent instability. Although several risk factors have been implicated, a younger age at the time of the primary dislocation, and male gender, are the factors that have been most consistently associated with a higher risk of recurrence.

Recent studies have suggested that primary arthroscopic repair of the anteroinferior detachment of the glenoid labrum (Bankart repair) may reduce the risk of subsequent recurrent instability and improve function, when compared with non-operative treatment. However, the unblinded or single-blind design of these studies fails to eliminate the potential for error due to observer or subject bias, and the therapeutic effects of the Bankart repair cannot be distinguished from those of the arthroscopic examination and washout alone. The latter may reduce the rate of subsequent instability, by promoting healing of the labral detachment, or by altering the patient's subsequent level of physical activity and compliance with rehabilitation protocols.

A clinical trial conducted recently in our Institution assessed the efficacy of a primary arthroscopic stabilisation after a first-time dislcoation, whilst controlling for the therapeutic effects of the arthroscopic examination and washout alone. We aimed to specifically test the null hypothesis, that an arthroscopic Bankart repair (ABR) would not produce an improvement in the rate of recurrent instability, functional outcome, range of movement, levels of patient satisfaction or total cost of treatment, when compared with an arthroscopic examination and washout (AWO) alone. The results of this study will be presented, together with an overview of the advantages and disadvantages of primary arthroscopic stabilisation.

This single centre study was a prospective analysis from 2000 to 2008, aiming to explore and characterise the incidence and management of orthopaedic injuries sustained from motorcycle-related accidents in children under 16 years of age in Far North Queensland. In addition, it aimed to recognise factors contributing to crash occurrence, injury pattern and severity.

Prospective survey data has been collected for the past eight years looking at various aspects of non-fatal motorcycle injuries in children up to the age of 16 years who present to Cairns Base Hospital. The study incorporated a simple 12-point questionnaire that was completed upon the child's first presentation to the hospital in either an in- or out-patient clinical setting. The aspects addressed by the survey included: number of accidents, use of safety gear, experience level, injury and management, and cause of the accident. Little research has been conducted on characterising the nature and occurrence of off-road motorcycle accidents in children and adolescents.

A total of 238 children were admitted to Cairns Base Hospital with injuries related to motorcycle accidents. The results of 210 children who sustained orthopaedic injuries are presented. Motorcycle accidents involving children were responsible for over 340 presentations to the Emergency department and for a total of more than 500 hospital bed-days upon admission.

The majority of accidents occurred off-road with over 40% on public property. An average of 11% of riders was female.

This study gives evidence that off-road motorcycle accidents in children are the result of inexperience, utilise a significant proportion of our orthopaedic resources, and that programs and policies directed at reducing the number of injuries from off-road motorcycle riding need implementation.

Nationally, experimental estimated Indigenous life expectancy was 59 years for Indigenous males (compared with 77 for all males) and 65 years for Indigenous females (compared with 82 years for all females). This is a difference of around 17 years for both males and females (ABS 2004).

The Australian Government has embarked on numerous educational and health campaigns addressing the disease processes that lead to such a stark difference in life expectancy. The results of these campaigns are evident, as the population of Indigenous Australians over 60 years of age has risen from 9968 (Census 1986) to 25604 (Census 2008). As a result, we are now beginning to see orthopaedic degenerative disease states such as osteoarthritis. This increase in the number of Iindigenous Australians suffering from osteoarthritis will result in a greater number of hip and knee joint arthroplasty for osteoarthritis. Although the largest populations of Indigenous patients reside in urban areas, notably Sydney (census count 41,800), Brisbane (41,400) and Perth (21,300), the Torres Strait region of Queensland has 83% of the Indigenous population in remote Australia (Census 2008).

This is reflected in the number of hip and knee joint arthroplasties performed through the orthopaedic department at the Cairns Base Hospital on indigenous patients, from a total of seven in 2001 to a total of 22 in 2008.

Retrospective analysis was conducted of those patients failing to attend their full complement of post-operative follow-up in the first year post total hip and knee joint arthroplasty for the eight year period from 2001 to 2008 at the Cairns Base Hospital. Within this period a total of 99 hip and knee arthroplasties were performed on indigenous patients. Over 30% of indigenous patients failed to attend their full complement of post-operative follow up in the first year post hip and knee joint arthroplasty.

Due to the increasing life expectancy of the indigenous population, more are presenting with orthopaedic degenerative disease states that require joint arthroplasty. The higher number of co-morbidities such as type II diabetes mellitus and peripheral vascular disease makes post operative follow up of the indigenous patient essential to avoid complications. The lack of follow up will undoubtedly lead to an inability to appropriately monitor the indigenous patient's recovery and/or decrease in morbidity post total hip and knee joint arthroplasty. Patient centered follow-up must be given greater consideration in relation to the Australian indigenous population such as an increase in outreach services, the provision of orthopaedic follow up by the local health practitioners in the rural and remote setting, maintaining up to date contact details along with affording the indigenous patient greater access to transport so as to improve follow up.
