In this study we evaluated whether the Instability Severity Index Score (ISIS) and the Western Ontario Shoulder Instability Index (WOSI) could detect those patients at risk of failure following arthroscopic Bankart repair. Between April 2008 and June 2010, the ISIS and WOSI were recorded pre-operatively in 110 patients (87 male, 79%) with a mean age of 25.1 years (16 to 61) who underwent this procedure for recurrent anterior glenohumeral instability.

A telephone interview was performed two-years post-operatively to determine whether patients had experienced a recurrent dislocation and whether they had returned to pre-injury activity levels. In all, six (5%) patients had an ISIS > 6 points (0 to 9). Of 100 (91%) patients available two years post-operatively, six (6%) had a recurrent dislocation, and 28 (28%) did not return to pre-injury activity. No patient who dislocated had an ISIS > 6 (p = 1.0). There was no difference in the mean pre-operative WOSI in those who had a re-dislocation and those who did not (p = 0.99). The pre-operative WOSI was significantly lower (p = 0.02) in those who did not return to pre-injury activity, whereas the ISIS was not associated with return to pre-injury activity (p = 0.13).

In conclusion, neither the pre-operative ISIS nor WOSI predicted recurrent dislocation within two years of arthroscopic Bankart repair. Patients with a lower pre-operative WOSI were less likely to return to pre-injury activity.

The December 2014 Oncology Roundup³⁶⁰ looks at: metaphyseal and diaphyseal osteosarcoma subtly different beasts; sports and endoprosthetic reconstruction of the knee; is curettage without tissue diagnosis sensible in cartilaginous tumours?; autoclaved autograft in bone tumour reconstruction; vascularised graft a step too far in bone defects?; interdigitated neoadjuvant chemoradiotherapy in high-grade sarcoma; predicting life expectancy in patients with painful metastasis; and osteolytic lesions of the hands and feet.

Aims

Our purpose was to determine the quality of current randomised controlled trials (RCTs) in hand surgery using standardised metrics.

Objectives

This investigation sought to advance the work published in our prior biomechanical study (Journal of Orthopaedic Research, 2016). We specifically sought to determine whether there are additional easy-to-measure parameters on plain radiographs of the proximal humerus that correlate more strongly with ultimate fracture load, and whether a parameter resembling the Dorr strength/quality characterisation of proximal femurs can be applied to humeri.

The October 2014 Research Roundup³⁶⁰ looks at: unpicking syndesmotic injuries: CT scans evaluated; surgical scrub suits and sterility in theatre; continuous passive motion and knee injuries; whether pain at night is melatonin related;venous thromboembolic disease following spinal surgery; clots in lower limb plasters; immune-competent cells in Achilles tendinopathy; and infection in orthopaedics.

Objectives

The purpose of this study was to compare the joint space width between one-leg and both-legs standing radiographs in order to diagnose a primary osteoarthritis of the knee.

Objectives

Alarm over the reported high failure rates for metal-on-metal (MoM) hip implants as well as their potential for locally aggressive Adverse Reactions to Metal Debris (ARMDs) has prompted government agencies, internationally, to recommend the monitoring of patients with MoM hip implants. Some have advised that a blood ion level >7 µg/L indicates potential for ARMDs. We report a systematic review and meta-analysis of the performance of metal ion testing for ARMDs.

The June 2014 Trauma Roundup³⁶⁰ looks at: BMP use increasing wound complication rates in trauma surgery; can we predict re-admission in trauma?; humeral bundle nailing; how best to treat high-angle femoral neck fractures?; hyperglycaemia and infection; simultaneous soft-tissue and bony repair in terrible triad injuries; metaphyseal malunion in the forearm leading to function restrictions; delayed fixation of the distal radius: not a bad option; and fasciotomies better with shoelaces

Objectives

The annual incidence of hip fracture is 620 000 in the European Union. The cost of this clinical problem has been estimated at 1.75 million disability-adjusted life years lost, equating to 1.4% of the total healthcare burden in established market economies. Recent guidance from The National Institute for Health and Clinical Excellence (NICE) states that research into the clinical and cost effectiveness of total hip arthroplasty (THA) as a treatment for hip fracture is a priority. We asked the question: can a trial investigating THA for hip fracture currently be delivered in the NHS?

The December 2014 Research Roundup³⁶⁰ looks at: demineralised bone matrix not as good as we thought?; trunk control following ACL reconstruction; subclinical thyroid dysfunction: not quite subclinical?; establishing musculoskeletal function in mucopolysaccharidosis; starting out: a first year in consultant practice under the spotlight; stroke and elective surgery; sepsis and clots; hip geometry and arthritis incidence; and theatre discipline and infection.

In a decidedly upper limb themed series of reviews this edition of Cochrane Corner summarises four new and updated reviews published by the Cochrane Bone, Joint and Muscle Trauma Group over the last few months. The tenacious reviewers at the Cochrane collaboration have turned their beady eyes to conservative treatments for shoulder dislocations and clavicle fractures along with evaluation of femoral nerve blocks in knee replacement and how to best manage entrapment injuries in children.

Instability is a common indication for early revision after both primary and revision total knee arthroplasty (TKA), accounting for up to 20% in the literature. The number of TKAs performed annually continues to climb exponentially, thus having an effective algorithm for treatment is essential. This relies on a thorough pre- and intra-operative assessment of the patient. The underlying cause of the instability must be identified initially and subsequently, the surgeon must be able to balance the flexion and extension gaps and be comfortable using a variety of constrained implants.

This review describes the assessment of the unstable TKA, and the authors’ preferred form of treatment for these difficult cases where the source of instability is often multifactorial.

Objectives

The PROximal Fracture of the Humerus: Evaluation by Randomisation (PROFHER) trial has recently demonstrated that surgery is non-superior to non-operative treatment in the management of displaced proximal humeral fractures. The objective of this study was to assess current surgical practice in the context of the PROFHER trial in terms of patient demographics, injury characteristics and the nature of the surgical treatment.

Patient specific instrumentation (PSI) uses advanced imaging of the knee (CT or MRI) to generate individualised cutting blocks aimed to make the procedure of total knee arthroplasty (TKA) more accurate and efficient. However, in this era of healthcare cost consciousness, the value of new technologies needs to be critically evaluated. There have been several comparative studies looking at PSI versus standard instrumentation. Most compare PSI with conventional instrumentation in terms of alignment in the coronal plane, operative time and surgical efficiency, cost effectiveness and short-term outcomes. Several systematic reviews and meta-analyses have also been published. PSI has not been shown to be superior compared with conventional instrumentation in its ability to restore traditional mechanical alignment in primary TKA. Most studies show comparative efficacy and no decrease in the number of outliers in either group. In terms of operative time and efficiency, PSI tended towards decreasing operative time, saving a mean of five minutes per patient (0 to 20). Furthermore, while some cost savings could be realised with less operative time and reduced instrumentation per patient, these savings were overcome by the cost of the CT/MRI and the cutting blocks. Finally, there was no evidence that PSI positively affected clinical outcomes at two days, two months, or two years. Consequently, current evidence does not support routine use of PSI in routine primary TKA.
