Shoulder resurfacing arthroplasty is a bone conserving option for patients with glenohumeral arthritis. We report the early results of this procedure at our unit with a minimum follow up of 2 years (mean follow up of 36 months).

A historical analysis of prospectively collected clinical data was reviewed on a consecutive series of 22 patients (mean age of 73 years) with end stage gleno-humeral arthrosis who had undergone humeral resurfacing hemiarthroplasty performed by a single surgeon. Pain and function were assessed using the Oxford shoulder score and patient satisfaction was recorded. Radiographs were evaluated for implant loosening.

82% of patients had significant improvement in their oxford shoulder score from pre-operatively to two years post-operatively. Complications included one case of intra-operative conversion to a stemmed hemiarthroplasty due to fracture of the humeral head, one case of adhesive capsulitis that required MUA and arthroscopic capsular release and two cases of revision to a total shoulder replacement for pain. Humeral resurfacing arthroplasty is a viable treatment option for glenohumeral arthritis with good short term results.

Introduction

The aim of the study was to compare and contrast the clinical outcome of conversion of practice of a shoulder surgeon from open to arthroscopic shoulder stabilisation for traumatic anterior shoulder instability.

Patients and Methods

Comparison of a cohort consecutive series of 24 patients treated by open stabilisation and a prospective consecutive cohort series of 30 patients treated by arthroscopic stabilisation. Clinical outcomes were assessed with Oxford Shoulder Score Instability (OSS-I) and a Patient Satisfaction Survey at a minimum of 1 year follow up. The operation time as well as cost analysis were also evaluated.

Aims

To establish if the principles of Enhanced Recovery, an evidence-based, integrated, multi-modal approach to improving recovery following colonic resection are transferable to elective orthopaedic primary arthroplasty surgery. The principles are to reduce the stress response provoked by surgery and eliminate the peri-operative catabolic state by optimally managing patients' metabolism, expectations, postoperative pain and mobility. This combination of interventions has not been tested in Orthopaedics before.

Methods

We conducted a single surgeon, consecutive patient, interventional, cohort study of primary total hip and knee arthroplasties. Our intervention was Enhanced Orthopaedic Recovery (EOR).

Enhanced Orthopaedic Recovery (EOR) is an evidence-based, integrated, multi-modal approach to improving recovery following elective orthopaedic surgery. The principles of EOR are to reduce time to functional recovery of postoperative patients safely with subsequent benefits to their length of stay in hospitals, their quality of life and health economics and outcomes. The combination of interventions used has been shown to be effective following major gastro-intestinal surgery but have not been tested in Orthopaedics until now. They aim to reduce the stress response provoked by surgery and the peri-operative catabolic state by optimally managing patient metabolism, post-operative pain, mobility and expectations.

Simple interventions along the patients’ journey include pre-operative educational classes, pre-operative carbohydrate loading, a (short) two hour fast ensuring surgery performed on anabolic patients, post operative pain and metabolic optimisation, empowering patients with ownership of their post-operative recovery and proactive post-discharge management. We found that these simple interventions translate well into elective orthopaedic arthroplasty surgery, can be achieved without additional cost and have little impact on intra-operative practice.

We conducted a single surgeon, consecutive patient, interventional, cohort study of lower limb primary joint arthroplasty surgery (primary total knee and primary total hip arthroplasty) in a busy district general hospital, 30 bed orthopaedic department. We reviewed the preceding 141 primary joint replacements (75 total hip and 66 total knee arthroplasties) before prospectively assessing the next 50 total hip and 32 total knee arthroplasties. A Mann-Whitney test between the two periods showed a highly statistically significant fall in time to discharge (median hospital stay 6.5 - 4 nights, p< 0.001). We noted no adverse effects as a result implementing EOR.

We have shown that by implementing EOR, reduced time to functional recovery and subsequent hospital discharge can be safely achieved with consequent quality of life and health economic benefits.
