Objectives

A rigorous approach to developing, delivering and documenting rehabilitation within randomised controlled trials of surgical interventions is required to underpin the generation of reliable and usable evidence. This article describes the key processes used to ensure provision of good quality and comparable rehabilitation to all participants of a multi-centre randomised controlled trial comparing surgery with conservative treatment of proximal humeral fractures in adults.

Prevalence of rotator cuff tears increases with advancing age (Ellman et al). In spite of proximal humeral fractures being common in the elderly, the influence of a coexistent rotator cuff tear on outcome has, to our knowledge, not been previously investigated. This study prospectively assessed whether the presence of a rotator cuff tear in association with a proximal humeral fracture influences functional prognosis.

85 patients treated conservatively for proximal humeral fractures were evaluated prospectively with Ultrasonography to determine the status of the rotator cuff. Every patient was managed by immobilisation of the arm in a sling for two weeks followed by a course of physiotherapy based on the Neer regime. Functional outcome was measured using the Constant shoulder score and the Oxford shoulder score, at 3-months and 12-months post injury.

Sixty-six of the 85 patients were female. The fractures were equally distributed for hand dominance. There were 27 patients with an undisplaced fracture, 34 patients with Neer's Type II fracture and 24 patients with Neer's Type III and IV fracture. There were 43 patients with full thickness cuff tears and 42 patients with no cuff tear or a partial thickness tear. Full thickness cuff tears were much more frequent in the over 60 year age group, which is consistent with the known increased incidence of cuff tears with increasing age.

The outcome scores at 3 and 12 months showed no statistically significant difference for either the Constant score or the Oxford score with regards to cuff integrity. Analysis of these scores showed no correlation between presence or absence of a full thickness cuff tear and shoulder function

The results of this study indicate that rotator cuff integrity is not a predictor of shoulder function at 12 months following proximal humeral fracture, as measured by outcome scores. This suggests that there is therefore no clinical indication for routine imaging of the rotator cuff in patients for whom conservative management is the preferred treatment option.

Large and massive rotator cuff tears can cause persistent pain and significant disability. These tears are often chronic with substantial degeneration of the involved tendons. Surgical treatment is challenging and the functional outcome after repair less predictable then for smaller tears. The aim of this study was to determine the functional outcome and rate of re-rupture after mini-open repair of symptomatic large and massive rotator cuff tears using a modified two-row technique.

Twenty-four patients, who were operated on under the care of a single surgeon between 2003 and 2006, were included in this study. Patients were assessed prospectively before and at a mean of 27 months after surgery using Constant Score and Oxford Shoulder Score. This assessment was carried out by an independent physiotherapist specialising in shoulder rehabilitation. At follow-up an ultrasound was carried out by a musculoskeletal radiographer to determine the integrity of the rotator cuff repair. Patient satisfaction was assessed using a simple questionnaire.

The mean Constant Score improved significantly from 36 preoperatively to 68 postoperatively (p< 0.0001), the mean Oxford Shoulder Score from 39 to 20 (p< 0.0001). Four patients (16.7%) had a re-rupture diagnosed by ultrasound. 87.5% of patients were satisfied with the outcome of their surgery. Tear size and repair integrity did not significantly influence functional outcome. 87.5% of patients were satisfied or very satisfied with the outcome of their surgery.

This study shows that the two-row repair of large and massive rotator cuff tears using a mini-open approach is an effective method of repair with a comparatively low re-rupture rate. It significantly improves the functional outcome and leads to a very high patient satisfaction. We conclude that these results justify repair of large to massive rotator cuff tears when possible, irrespective of chronicity of symptoms.

The aim of this study was to determine the functional outcome and rate of re-tears following mini-open repair of symptomatic large and massive tears of the rotator cuff using a two-row technique.

The 24 patients included in the study were assessed prospectively before and at a mean of 27 months (18 to 53) after surgery using the Constant and the Oxford Shoulder scores. Ultrasound examination was carried out at follow-up to determine the integrity of the repair. Patient satisfaction was assessed using a simple questionnaire.

The mean Constant score improved significantly from 36 before to 68 after operation (p < 0.0001) and the mean Oxford Shoulder score from 39 to 20 (p < 0.0001). Four of the 24 patients (17%) had a re-tear diagnosed by ultrasound. A total of 21 patients (87.5%) were satisfied with the outcome of their surgery. The repair remained intact in 20 patients (83%). However, the small number of re-tears (four patients) in the study did not allow sufficient analysis to show a difference in outcome in relation to the integrity of the repair.

Introduction: Scoring systems for assessment of shoulder function are invaluable tools in determining changes in a patient’s condition. We utilised two commonly used assessment tools in patients with conservatively treated proximal humeral fractures to establish their behaviour in this patient group.

Methods: OSS and Constant Scores were collected prospectively at 3 and 12 months post injury, for 103 consecutive patients treated conservatively for proximal humeral fractures. Comparison of the scores was undertaken by creating scattergraphs, calculating Pearson’s correlation coefficient and producing Bland and Altman plots. Sensitivity to change was calculated using paired t-tests. Linear regression analysis was finally performed to predict Constant Score from the OSS.

Results: 177 sets of scores were collected. The scores correlated well with a correlation coefficient (r) of 0.84 (p< 0.001,n=177). This relationship was equally strong at 3 (r=0.77 (p< 0.001,n=94)) and 12 months (r=0.87 (p< 0.001,n=83)) and demonstrated a clear relationship between the scoring systems. Bland and Altman plots showed good agreement between the scores. Both scores were sensitive to change over time (OSS (t(81)=6.14,p< 0.001), Constant (t(80)=−10.27,p< 0.001)). Regression analysis produced a regression equation (R2=0.70) of: Constant Score=99.3-(1.67 times OSS). This level of model fit was statistically significant (F(1,175)=412.8,(p< 0.001))

Conclusion: This study provides information about the behaviour of two frequently used functional scoring systems in patients with proximal humeral fractures. Based on our finding we feel that these scores are appropriate assessment tools in these patients. The OSS may also be considered as an alternative for assessing longer term follow up as, being solely subjective, it is easier to administer and correlates well with the Constant Score.

Background: Prevalence of rotator cuff tears increases with advancing age (Ellman et al). In spite of proximal humeral fractures being common in the elderly, the influence of a coexistent rotator cuff tear on outcome has, to our knowledge, not been previously investigated.

Aim: This study assess whether the presence of a rotator cuff tear in association with a proximal humeral fracture influences prognosis.

Every patient was managed by immobilisation of the arm in a sling for three weeks followed by a course of physiotherapy based on the Neer regime.

Full thickness cuff tears were much more frequent in the over 60 year age group, which is consistent with the known increased incidence of cuff tears with increasing age.

The outcome scores at 3 and 12 months showed no statistically significant difference for either the Constant score or the Oxford score with regards to cuff integrity. Analysis of these scores showed no correlation between presence or absence of a full thickness cuff tear and shoulder function

Conclusion: The results of this study indicate that rotator cuff integrity is not a predictor of shoulder function at 12 months following proximal humeral fracture, as measured by outcome scores. This suggests that there is therefore no clinical indication for routine imaging of the rotator cuff in patients for whom conservative management is the preferred treatment option.

Background: The incidence of proximal humeral fractures is increasing with time. There is continuing debate about the indications for surgical intervention for this relatively common injury. Baseline data on functional outcome is essential in order to study the effect of surgical intervention. Functional outcome scores provide reliable and valid judgments of health status and the benefits of treatment. During our preparation of a study proposal on this topic to the Health Technology Assessment Program recently, we noted the lack of such data on outcome scores in the current literature.

Aim: To assess the functional outcome using the Constant and Oxford scores in patients treated conservatively for proximal humeral fractures.

Methods: We prospectively studied 103 consecutive patients who were treated conservatively for proximal humeral fractures. Patient demographics, fracture type (Neer), hand dominance and comorbidity were recorded. Constant and Oxford shoulder scores were recorded 3 and 12 months post injury.

Results: The average Constant shoulder score for males was significantly higher (better outcome) and the Oxford shoulder score significantly lower (better outcome) as compared to females. The scores were not affected by hand dominance. Although the raw scores tended to be worse with 3 or 4 part fractures the difference in the mean scores between the various Neer fracture types did not reach convential levels of significance.

A trend towards lesser degrees of improvement in the outcome scores was noted with increasing age. The degree of improvement in the outcome scores was not affected by sex, limb dominance or fracture type (Neer’s classification).

Conclusion: This study indicates the average behaviour of the Constant and Oxford scores with conservative treatment of proximal humeral fractures. This data should help with sample size and power calculations when studying interventions for this injury. We hope that this data will provide a baseline to help inform future study designs on proximal humeral fractures.

Introduction and Aims: To determine if the surface area of partial thickness (< 50%), Bursal side tears of the cuff influence outcome following Subacromial Decompression.

Method: Shoulder function using Constant score (CS) was recorded before and a minimum of one year after Arthroscopic Subacromial Decompression (ASD) in patients undergoing surgery for primary impingement. In patients who had partial thickness, Bursal side tears (BT), the length of the tear in its largest dimension (surface area) was measured. These patients were divided into two groups according to the tear surface area (≤9 mm and ≥10mm) .To determine whether having a BT (< 50% thickness) or its surface area affect pre- and post-operative CS, t-tests were performed.

Results: 110 patients underwent ASD over a one-year period for primary impingement. Twenty-two patients with partial thickness BT and 18 patients with intact rotator cuff were included in this study. In 10 patients, the BT was ≤9 mm (mean 7 mm) and in 12 patients BT was ≥10mm (mean 13 mm).

Statistical analysis of pre- and post-operative Constant scores showed that, in ≤9 mm group CS increased significantly by 21.5, p=0.02, 95% CI (4.9, 38.1). CS increased in ≥10mm group by 22.8, p< 0.01, 95%(11.5, 34.1). Comparing the change in CS between these two groups with different tears size, there was no significant difference (2-sample t-test, t=0.15, 20df, p=0.88).

To determine whether having BT tear affects pre- and post-operative Constant scores, all BTs were grouped together and compared with the group of patients with intact cuff.

In the group with BTs, average Constant scores increased significantly (paired t-test, t=5.24, 21df, p< 0.01) by 22.2 with 95% CI (13.4, 31.0).

In the group with no tears, average Constant scores increased significantly (paired t-test, t=5.17, 17df, p< 0.01) by 26.6, 95% CI (15.8, 37.5).

Comparing the levels of absolute change in Constant scores from pre- to post-operation between the two groups there is no difference in outcome between patients with a tear and those without a tear (2-sample t-test, t=1.03, 38df, p=0.31).

Conclusion: We conclude that ASD yields satisfactory results in patients with BTs involving < 50% thickness, irrespective of the surface area of the tear.

Purpose: To analyse preliminary outcomes of a new synthetic ligament used for reconstructing coraco-clavicular ligament in acromio-clavicular joint disruption.

Methods: Patients who underwent acromio-clavicular joint stabilisation using Nottingham Surgilig were followed up at average of 40 months (range 6–80 months) post operation. Apart from clinical and radiological assessment, the Constant-Murley scoring system and the Imatani scores were also used to measure outcome.

Results: Twenty patients underwent this operation and data was available on 19 of them. These patients had their operation after an average of 18 months following injury, during which period they had conservative treatment, except in 2 cases where a Weaver Dunn operation was performed initially.

The mean Constant score was 88 (s.d. 12). The mean Imatani score was 86 (s.d. 16). Most patients were satisfied with the operation (90%). There was one case of rupture through the central portion of the Surgilig, and following extensive laboratory analysis, the ligament has been modified since. One patient had a fracture of his coracoid while lifting heavy weights. In 4 patients there was clinical and radiological evidence of loosening of the screw but only 1 complained of this being a problem.

Conclusion: This is an initial medium term outcome analysis of the Nottingham Surgilig. Our results are promising and justify further use and evaluation of this relatively new technique.

Systematic studies are required to examine the effects on outcomes of alternative treatments and surgical techniques in the management of Orthopaedic conditions. Functional outcome scores provide reliable and valid judgments of health status and benefits of the treatment. We undertook a prospective study to assess the functional outcome in patients treated conservatively for proximal humeral fractures.

103 patients treated conservatively for a proximal humeral fracture were followed prospectively. Constant shoulder score and Oxford shoulder score were recorded at 3 months and 12 months follow-up.

A trend towards lesser degrees of improvement in the outcome scores was noted with increasing age. The degree of improvement in the outcome scores was not affected by sex, limb dominance or fracture type (Neer’s classification).

This information gives a guide to average behaviour in different groups of individuals with conservative treatment for proximal humeral fractures. We could then using this data postulate what would constitute a clinically relevant difference and calculate study numbers required while assessing other form of treatments for such fractures

Aim: The prevalence of rotator cuff tears increases with advancing age. Proximal humeral fracture are also common in the elderly, but the influence of a coexistent rotator cuff tear on clinical outcome following fracture has not been previously investigated.

Method: In this study 85 patients treated conservatively for proximal humeral fractures were evaluated with ultrasonography to determine the status of the rotator cuff. Outcome was evaluated using the Constant shoulder score and Oxford shoulder score, and recorded at 3 months and 12 months follow up. The null hypothesis is that there is no correlation between the presence of absence of cuff tear following fracture and clinical outcome.

The data was analysed to determine if the presence of a full thickness rotator cuff tear influenced functional outcome in these patients.

The null hypothesis has not been disproved. There is no statistically significant difference in outcome with presence of an associated full thickness rotator cuff tear with proximal humeral fractures.

Conclusion: At present this study suggests that there is no indication for routine ultrasonography evaluation of the rotator cuff following proximal humerus fracture.

To determine if the surface area of partial thickness (< 50%), Bursal side tears of the cuff influence outcome following Subacromial Decompression.

Shoulder function using Constant score (CS) was recorded before and a minimum of one year after Arthroscopic Subacromial Decompression (ASD) in patients undergoing surgery for primary impingement. In patients who had partial thickness, Bursal side tears (BT), the length of the tear in its largest dimension (surface area) was measured. These patients were divided into two groups according to the tear surface area (≤9 mm and ≥10mm) .To determine whether having a BT (< 50% thickness) or its surface area affect pre and postoperative CS, t-tests were performed.

110 patients underwent ASD over a one-year period for primary impingement. 22 patients with partial thickness BT and18 patients with intact rotator cuff were included in this study. In 10 patients, the BTwas ≤9 mm (mean7mm) and in 12 patients BTwas ≥10mm(mean13mm). Statistical analysis of Pre-& postoperative Constant scores showed that, in ≤9 mm group CS increased significantly by 21.5, p=0.02, 95% CI (4.9, 38.1). CS increased in ≥10mm group by 22.8, p< 0.01, 95%(11.5, 34.1). Comparing the change in CS between these two groups with different tears size, there was no significant difference (2-sample t-test, t=0.15, 20df, p=0.88).

To determine whether having BT tear affects pre- and post-operative Constant scores, all BTs were grouped together and compared with the group of patients with intact cuff.

In the group with BTs, average Constant scores increased significantly (paired t-test,t=5.24,21df,p< 0.01) by 22.2 with 95% CI (13.4, 31.0). In the group with no tears, average Constant scores increased significantly (paired t-test,t=5.17,17df,p< 0.01) by 26.6, 95% CI (15.8, 37.5).

Comparing the levels of absolute change in Constant scores from pre- to post-operation between the two groups there is no difference in outcome between patients with a tear and those without a tear (2-sample t-test, t=1.03, 38df, p=0.31).

We conclude that ASD yields satisfactory results in patients with BTs involving < 50% thickness, irrespective of the surface area of the tear.
