Ankle fractures in the elderly are common and have a mortality rate of 12% within the first year. Treatment is challenging due to osteoporotic bone and patient co-morbidities. Many patients struggle with non-weight-bearing (NWB) and presently there is no consensus in the literature regarding optimum management of these injuries.

We hypothesised that early weight-bearing in frail patients, Clinical Frailty scale (CFS) score of 4 or more will reduce morbidity and allow patients to return to their usual place of residence faster without jeopardising clinical outcome.

We conducted a retrospective analysis of 80 patients aged over 65 years managed at Fiona Stanley Hospital for ankle fractures between January 2016 and 2018. Patients were divided into two cohorts: 40 patients managed NWB and 40 who were permitted to weight-bear as tolerated (WBAT). Patients were stratified as fit (CFS 1–3) or frail (CFS 4+). Primary outcomes were one-year mortality, return to primary residence at six weeks and complications. Secondary outcomes included length of acute hospital stay and rehab stay.

For frail patients, those managed NWB stayed in rehab for 19 days longer (p=0.03) and had 28% more complications (p=0.03). By 6 weeks, fewer patients returned to full weight-bearing (p=0.03) and fewer patients had returned home (p=0.01). For fit patients, there were no significant differences in primary outcomes between NWB and WBAT.

Our novel study categorising patients by CSF demonstrates that early mobilisation in frail patients results in improved outcomes. Currently there is no formal treatment protocol for the management of ankle fractures in the elderly, and we hope that our proposed algorithm will assist surgeons at our institution and elsewhere.

Our study suggests that WBAT may benefit frail patients. We propose a protocol to assist in the management of geriatric ankle fracture patients based on clinical frailty scores.

Aims

Leg length discrepancy (LLD) is a common pre- and postoperative issue in total hip arthroplasty (THA) patients. The conventional technique for measuring LLD has historically been on a non-weightbearing anteroposterior pelvic radiograph; however, this does not capture many potential sources of LLD. The aim of this study was to determine if long-limb EOS radiology can provide a more reproducible and holistic measurement of LLD.

Aims

A proximal femur fracture (PFF) is a common orthopaedic presentation, with an incidence of over 25,000 cases reported in the Australian and New Zealand Hip Fracture Registry (ANZHFR) in 2018. Hip fractures are known to have high mortality. The purpose of this study was to determine the utility of the Clinical Frailty Scale (CFS) in predicting 30-day and one-year mortality after a PFF in older patients.

Introduction

Custom flanged acetabular components (CFAC) have been shown to be effective in treating complex acetabular reconstructions in revision total hip arthroplasty (THA). However, the specific patient factors and CFAC design characteristics that affect the overall survivorship remain unclear. Once the surgeon opts to follow this treatment pathway, numerous decisions need to be made during the pre-operative design phase and during implantation, which may influence the ultimate success of CFAC. The goal of this study was to retrospectively review the entire cohort of CFAC cases performed at a large volume institution and to identify any patient, surgeon, or design factors that may be related to the long-term survival of these prostheses.

Introduction

We propose that Total Hip Replacement with correction of fixed flexion deformity of the hip and exaggerated lumbar lordosis will result in relief of symptoms from spinal stenosis, possibly avoiding a spinal surgery. A sequence of patients with this dual pathology has been assessed to examine this and suggest a possible management algorithm.

Introduction: We present here the clinical features and management strategies of patients with gluteus medius and minimus enthesopathy.

Methodology: We studied seven patients with lateral hip pain and tenderness on palpation, worse over the tip of the greater trochanter. All of them had a positive Trendelenburg’s sign, and a transient relief of pain on injecting local anaesthetic in the abductor mechanism. All of these patients were tertiary referrals from the rheumatologists, who had at least once injected them with corticosteroids.

Results: Four of these seven patients underwent exploration. An insertional tendinopathy of the abductors was noted in all the patients, and was debrided. Two of the patients had, in addition, a tear in the gluteus medius tendon, which was repaired. One patient had an injection of local anaesthetic and Aprotinin in the abductor mechanism with resolution of symptoms.

Discussion: Gluteus medius and minimus enthesopathy is a distinct clinical entity. Although the condition has been described in the radiological literature, we were unable to find any reference to the orthopaedic management of this condition. We observed only a small number of patients, and we are thus unable to provide definite answers. Patients presenting with the above clinical features warrant consideration of the diagnosis of abductor enthesopathy. Ultrasound scan or MRI scan helps in confirming the diagnosis. At present, our management protocol involves injecting a local anaesthetic / Aprotinin in the abductor mechanism. However, we are cautious in injecting more than once, as, at operation, we have observed necrosis of the abductor mechanism at its insertion in two patients, similar to that described for Achilles tendon. If this fails, we undetake surgical exploration. The exact surgical procedure is difficult to predict and may involve debridement and repair of the pathological tendon.

Introduction. Leg length inequality post total hip arthroplasty is a source of patient dissatisfaction. In adult DDH femoral length equality is assumed. Empirically, a longer femur has been observed on the affected side in the presence of unilateral DDH; restoration of the hip centre in this situation may lengthen the affected leg.

Aim. Assessment of femoral length variation in adults with unilateral and bilateral DDH.

Method. Retrospective observation study of 17 adults with unilateral and 7 adults with bilateral DDH. Femoral lengths assessed using CT measurements.

Results. Unilateral DDH. The ipsilateral femur was longer in 11 patients (63%) The degree of femoral lengthening was between 5 and 10 mm. Bilateral DDH. The femur with the greater degree of DDH was longer by a mean of 7.5 19.3 mm .

Conclusion. In the presence of DDH, asymmetry of femoral lengths is common and unpredictable. Careful femoral length assessment ( with CT leg lengths) is advised preoperatively in patients with DDH. This will alert the surgeon and patient to the possible risk of post operative ipsilateral leg lengthening.
