Summary Statement

In this study, massive rotator cuff tears were treated using an absorbable collagen-based patch or a non-absorbable synthetic patch. Results demonstrated the efficacy of the use of the synthetic prolene patch especially for elderly patients

The aim is to evaluate the effectiveness of pericardium patch as a tendon augmentation graft in the repair of massive rotator cuff tear. This is prospective study analysis of a consecutive series of 60 patients who underwent open repair of a massive rotator cuff tear with patch between 1999 and 2007. The inclusion criteria were: symptomatic with pain, deficit of elevation, not responsive to the physiotherapy, tear size (massive: 2 or more tendons), minimum follow-up of 2 years since surgery, active and motivated patients. All were assessed preoperatively with plain radiographs (anteroposterior and axillary views), ultrasound and NMR of the shoulder. The study group consistent of 60 patients (39 men and 21 women) with the mean age of was 66 years (range, 46–81). The mean duration of symptoms before repair was 18 months (range 3–48). Patients were assessed with UCLA score, visual analog scale (Vas scale) and ultrasound preoperatively, at 1 year, and at 3 years. The change in UCLA scores, Vas scale were analyzed with the paired Student's test, assuming a normal distribution of the total score. Satisfactory results were achieved in 49 patients: mean preoperative UCLA score improved from 9.3 to 16.9 at final follow-up.

For pain, the mean preoperative value of Vas scale was 9,1, postoperative mean value was 4.9. Range of motion and abduction power improved not significantly after surgery, although patients satisfaction levels were high. Imaging studies identified intact patch in 15 patients and patch detachment in 45. No adverse side effects (infection, rejection, allergy) were reported during the study period.

The results of our study suggest that patients (appropriately selected) with a massive full-thickness rotator cuff tear can be expected to have a pain relief after repair, but not a significantly improved of functional outcome.

The shoulder girdle is an extremely mobile joint. Rotator cuff tears alter the existing equilibrium between bony structures and muscles. The “subacromial impingement syndrome” resulting from this unbalance leads to an extension of the rotator cuff lesion.

Many authors have postulated a “mechanism of compensation”, but its existence still requires evidence. According to this model, the longitudinal muscles of the shoulder and the undamaged muscles of the rotator cuff would be able to functionally compensate, supersede the function of rotator cuff, and reduce symptoms.

The aim of this study was to evaluate muscular activation of the medium fibers of deltoid, the superior fibers of pectoralis major, the latissimus dorsi and the infraspinatus by a superficial electromyographic study (EMG) and the analysis of kinematics in patients with a massive rotator cuff tear.

We evaluated 30 subjects: 15 had pauci-symptomatic massive rotator cuff tear (modest pain and preserved movement), and 15 were healthy controls.

Paired t-test showed significant different activations (p< 0.05) of these 4 muscles between the pathological joint and the healthy one in the same patient.

The unpaired t-test, after comparing the mean EMG values of the 4 muscles, produced a significant difference (p< 0.05) between the experimental group and control group.

This study showed that a mechanism of muscular compensation is activated in patients suffering from rotator cuff tear, involving the deltoid and the infra-spinatus muscle, as already presented in literature, but also demonstrated the activation of 2 other muscles: the latissimus dorsi and the pectoralis major. It is, therefore, probable that, in these patients, these muscles, which would not normally pull the head of the humerus downwards, adapt in order to compensate for the pathological situation. We believe that these data are valuable in the surgical and rehabilitation planning in patients with a massive rotator cuff tear.

The aim of the study is to evaluate the results obtained in patients older than 70 years who were treated with open surgical repair for massive ruptures of the rotator cuff and the functional outcome.

This is a retrospective analysis of a consecutive series of 280 patients who underwent open repair of a massive rotator cuff tear between 1999 and 2003. The inclusion criteria were: age 65 or over, symptomatic with pain, deficit of elevation, not responsive to the physiotherapy, tear size > = 5 cm, minimum follow-up of 2 y since surgery. All were assessed preoperatively with plain radiographs (anteroposterior and axillary views) and nmr of the shoulder. Patients were assessed with the Costant score, Simple Shoulder test, UCLA score before and after surgery. Pain was assessed by use of a visual analog scale. The mean age of patients was 75b years (range 65–91). There were 41 men and 28 women. The mean duration of symptoms before repair was 18 months (range 1–58). The dominant arm was affected in 54 patients (78%). The change in UCLA scores, SST, Costant score and their subcomponents were analyzed with the paired Student’s test, assuming a normal distribution of the total score. In an exploratory analysis trying to identify preoperative variables that could be associated with a good surgical outcome, a multivariate logistic regression analysis was performed including the following variables: age equal or more than 80 years, sex history, shoulder different affected, UCLA score, SST, costant score and use of formal physical therapy. Satisfactory results were achieved in 250 patients: the mean preoperative UCLA score was 9.3, Costant score 45, and the mean score after surgery was 16.9 and 65 rispectively. The mean preoperative function score was 2.4, after surgery was 8.1. The UCLA preoperative score for active forward flexion averaged 1.3 (30°–90°), and postoperative rating increased to 4.5 points (p=0,0001)corresponding to an active forward flexion between 120° and 150°.

The surgical technique for treatment of massive rotator cuff tears, more than 5 cm, with loss of substance and tendon retraction, is still not well defined by the international orthopaedic community. A specific rehabilitation regimen or arthroscopic débridement may be insufficient in active patients who continue to suffer from pain and muscular fatigue in active forward elevation. We treated 20 patients, 14 men and 6 women, with an average age of 52 years (range 40–69) with the surgical technique consisting in acromion decompression, stabilisation of the cuff lesion with anchors, application of a prolene membrane and using a deltoid muscular flap as reinforcement. Deltoid flap is created by splitting the deltoid muscular fibres in front of the anterior border of the acromion. The inferior part of deltoid is sutured to the tendon above the synthetic membrane.

The mean patient follow-up was 24 months. The pain was completely relieved in 85% of subjects, The joint mobility increased significantly in flexion, abduction and external rotation; however, the internal rotation did not improve.

We propose this surgical technique as the procedure of choice for treating retracted ruptures of the supraspinatus associated with lesions of the supra- and the infra-spinatus.

Nowadays it is well known that both a clinical examination and an imaging investigation (MRI/CT scans) are useful in order to provide surgeons with complete informations about the proposed treatment for shoulder pain. The purpose of this study was to evaluate the diagnostic sensitivity of the Neer, Hawkins, Jobe, Lift-off and Infraspinatus tests in diagnosing rotator cuff tears and compare this with what was found during surgery.

From 2001 to 2003, data from 430 patients who underwent shoulder open surgery, performed by a single surgeon, were documented. The results showed that the Jobe test has a sensitivity of 97.5% and positive prognostic value (PPV) of 80.3% and negative prognostic value (NPV) of 90.9% for the presence of a supraspinatus lesion; the Neer, Hawkins and Yokum tests have a sensitivity close to 95% for assessing subacromial bursitis; the Lift-off and Infraspinatus tests have a sensitivity close to 70% for assessing the degree of lesion and identify a severe lesion with a NPV over 83%. The Lift-off and Infraspinatus tests also provide information concerning muscular trophism and concerning retraction and degeneration of tendons.

According to our results, clinical evaluation of shoulder pain should be supported by imaging investigations for diagnosis of rotator cuff tear.

Two-part surgical neck fractures, two-part greater tuberosity fractures and three- and four-part fractures of the proximal humerus represent a frequently encountered clinical problem. Many types of conservative treatments have been proposed, with a poor functional outcome, however; when the fracture fragments are displaced, surgery is required.

Because the open reduction and the internal fixation disrupts soft tissue and increases the risk of avascular necrosis of the humeral head, closed or minimally open reduction and percutaneous pin fixation should represent an advantage.

We report on 31 patients affected by fractures of the proximal humerus (n=6, two-part surgical neck fractures; n=5, with two-part greater tuberosity fractures; n=10, three-part fractures; and n=11, four- part fractures) treated with minimally open reduction and percutaneous fixation. The average age was 57 years. Most of the four-part fractures were of the valgus type with no significant lateral displacement of the articular segment. A small skin incision was performed laterally at the shoulder and a rounded-tipped instrument was introduced to obtain the fracture reduction; this latter was stabilised by percutaneous pins and cannulate screws.

A satisfactory reduction was achieved in most cases. The average follow-up was 24 months (range 18–47). Only one patient, with four-part fractures associated with lateral displacement of the humeral head, showed avascular necrosis and received a prosthetic implant.

Minimally open reduction and percutaneous fixation is a non-invasive technique with a low risk of avascular necrosis and infection. This surgical technique allows a stable reduction with minimal soft tissue disruption and facilitates postoperative mobilisation.

The surgical approach to compressive syndromes of the thoracic outlet of vascular or nervous origin represents, for anatomical and historical reasons, an important issue for orthopaedic surgeons. Today’s angiographic techniques give an easy and unequivocal insight of the vascular and non-vascular (indirect) nature of the disease and, consequently, give more solid indications for surgery than before. A series of 35 cases, 21 women and 14 men with an average age of 39 years, of thoracic outlet syndrome (TOS) of vascular origin is presented here. The causes of compression were cervical rib (n=24), soft tissue anomalies (n=10) and scar tissue after clavicular fracture (n=1). During surgery, two subclavian artery aneurysms containing intraluminal thrombus and one subclavian artery occlusion were found. Presenting features of cases with arterial TOS included: hand ischaemia (n=32), transient ischaemic attack (n=3) and claudicatio or vasomotor phenomena during the arm in hyperabduction (n=3). Two patients with venous TOS developed hand oedema during arm hyperabduction, and another patient had axillary-subclavian venous thrombosis. In all cases decompressive procedures using a combined supraclavicular and infraclavicular approachs were performed. Decompression were achieved by cervical rib excision (n=24), combined cervical and first rib excision (n=10) and first rib excision (n=1). In all cases, division of all tissue elements was also accomplished. Associated vascular procedures included resection and replacement of two subclavian aneurysms.

The mean follow-up period was 3 years and 2 months (range 1–6). Complete resolution of symptoms with a return to full activity was achieved in all cases. The medium-term clinical results suggest that the surgical indication for TOS, if supported by digital angiography, is justified and effective.
