Sternoclavicular joint infections are uncommon but severe and complex condition usually in medically complex and compromised hosts. These infections are challenging to treat with risks of infection extending into the mediastinal structures and surgical drainage is often faced with problems of multiple unplanned returns to theatre, chronic non-healing wounds that turn into sinus and the risk of significant clinical escalation and death. Percutaneous aspirations or small incision drainage often provide inadequate drainage and failed control of infection, while open drainage and washout require multidisciplinary support, due to the close proximity of the mediastinal structures and the great vessels as well as failure to heal the wounds and creation of chronic wound or sinus. We present our series of 8 cases over 6 years where we used the plan of open debridement of the Sternoclavicular joint with medial end of clavicle excision to allow adequate drainage. The surgical incision was not closed primarily, and a suction vacuum dressing was applied until the infection was contained on clinical and laboratory parameters. After the infection was deemed contained, the surgical incision was closed by local muscle flap by transferring the medial upper sternal head of the Pectoralis Major muscle to fill in the sternoclavicular joint defect. This technique provided a consistent and reliable way to overcome the infection and have the wound definitively closed that required no secondary procedures after the flap surgery and no recurrence of infections so far. We suggest that open and adequate drainage of Sternoclavicular joint staged with vacuum dressing followed by pectoralis major local flap is a reliable technique for achieving control of infection and wound closure for these challenging infections

Introduction:. Tuberosity healing is strongly correlated with functional results in all series of three- and four-part fractures of the proximal humerus treated by hemiarthroplasty. We formed a working group to improve position of the implant and fixation of the tuberosities on an implant specifically intended for traumatology. Material and Methods:. An anatomic study on 11 cadavers and a prospective multicentre clinical study of 32 cases were performed to validate extrapolable original solutions at the patient scale: placement of the stem at a height indicated in relation to the insertion of the clavicular bundle of the pectoralis major, locking of the stem, placement (based on bone quality) of a variable volume metaphyseal frame (offset modular system® OMS®), avoiding medialisation of the tuberosities, and fixation of the tuberosities using strong looped sutures, brightly coloured so that they can be located more easily. Evaluation by Dash score and Constant score was correlated with positioning of the tuberosities using radiographs. Results:. The clinical study enabled a distance of the top of the head to pectoralis major of 5.5 cm +/− 5 mm to be determined, confirming the results of the anatomic study and data from the literature. The distal double-locking ancillary device and the suturing technique for the tuberosities using looped sutures was judged to be effective by all of the surgeons. 23 patients (5 males, 9 CT4 and 8 CT3) with an mean age 69,6 (33–90) were operated on by 3 senior surgeons and reviewed at a mean follow-up of 17,3 months (6–24). All patients were seen again at 3 months and 6 months and the average motion at last follow was abduction of 90,7° (140–40), active anterior elevation of 113,25° (160–60), and external rotation of 43,2°(55–30). One complication was noted: inadequate position of a locking screw. In the 17 patients operated without oms® 50% had adequate initial positioning of the tuberosities and 10% secondary displacement. In comparison the 6 patients operated with the oms® 100% had adequate initial positioning of the tuberosities and no secondary displacement occurred. Discussion:. The series from Sofcot, Boileau, and more recently Reuther yielded results of 40 to 66% malposition or nonunion of the tuberosities. The initial clinical results from our series are encouraging and demonstrate that using a variable volume metaphyseal frame in synthesis of the tuberosities with control of the height of the implant is reliable. This multicentre study should be extended by a more long-term analysis

Background:. It is not well known how different external loads influence shoulder kinematics and muscle activity in patients with shoulder prostheses. Study objective: define shoulder kinematics and determine the scapulothoracic contribution to total shoulder motion, in combination with shoulder muscle activity and the degree of co-contraction, of patients with total (TSA) and reverse shoulder arthroplasties (RSA) and healthy individuals during rehabilitation exercises using different loading conditions. Methods:. Shoulder motions (anteflexion and elevation in the scapular plane) of 17 patients (20 shoulders) with a TSA, 8 patients (9 shoulders) with a RSA and 15 healthy subjects were measured using anelectromagnetic tracking device. A force transducer recorded force signals during loaded conditions (without external load, 1 kg and elastic resistance). Electromyographic (EMG) activity of the deltoid (anterior, middle, posterior parts), latissimus dorsi, pectoralis major (clavicular and sternal parts), teres major and serratus anterior was recorded and the degree of co-contraction calculated. Results:. The scapula contributed more to movement of the arm in subjects with prostheses compared to healthy subjects and during loaded versus unloaded tasks. Glenohumeral elevation angles during anteflexion were significantly higher in the TSA than in the RSA group. Higher activity of the middle and posterior deltoid was found in the TSA group compared to healthy subjects and for the pectoralis major (sternal part) in the RSA group compared to TSA and healthy subjects. For all muscles, except the serratus anterior, activity was lower for unloaded tasks compared to 1 kg dumbbell and elastic band resistance. No main effect of group or load for degree of co-contraction was detected in both exercises. Conclusions:. Differences in contribution of the scapula to total shoulder motion between patients with different types of arthroplasties were not significant, but differed both compared to healthy subjects. Scapular kinematics of patients with shoulder arthroplasties were influenced by implementation of external loads, however, not by the type of load. There were no differences in muscle activity and degree of co-contraction between patient groups

Introduction. Rehabilitation after shoulder arthroplasty is a fundamental in enabling patients achieve a good functional outcome. Therapists must consider the underlying diagnosis, operative technique employed and rotator cuff integrity, amongst other factors, in order to select the most appropriate exercise regime. There is an absence of comprehensive studies in the literature with regard to shoulder rotational exercises. Therefore, this study aimed to describe the shoulder girdle muscle activation strategies during eight commonly cited rotational shoulder exercises. Method. Thirty healthy subjects with no history of shoulder problems participated in the study. EMG was recorded from 16 shoulder girdle muscles (surface electrodes: anterior, middle and posterior deltoid, upper, middle and lower trapezius, upper and lower latissimus dorsi, upper and lower pectoralis major; fine wire electrodes: supraspinatus, infraspinatus, subscapularis and rhomboid major) using a telemetry based EMG system. Five external and three internal rotation exercises were included (table 1). Signal acquisition and processing were in accordance with standardised guidelines. Amplitude normalisation was to external and internal rotation maximum voluntary contraction as appropriate. Mean EMG amplitudes between exercises were compared using repeated measures ANOVA. Data for muscle groups was calculated by averaging the activation of the component muscles. Results. External Rotation Exercises: significantly higher levels of deltoid activation were seen in external rotation at 90° abduction compared to the other external rotation exercises (73.7% vs 12.4–27.2%; p < 0.001). Peri-scapular muscle activation was highest in external rotation at 90° abduction and prone external rotation (76.7–83.2% vs 28.2–45.5%; p = 0.013 − <0.001). Activation of latissimus dorsi and teres major was significantly higher during prone external rotation (64.1% vs 18.1–48.4%; p < 0.001). Activation of the rotator cuff muscles was similar across all exercises. Internal Rotation Exercises: the highest deltoid activity was seen during internal rotation at 90°abduction, followed by zero-position internal rotation. It was lowest during internal rotation at 0°abduction (261.6% vs 190.1% vs 40.9%; p = 0.003 − <0.001). A similar activation pattern was also seen for peri-scapular muscles. The highest activation of pectoralis major was seen during zero-position internal rotation (25.4% vs 4.9–15.7%; p = 0.002 − <0.001). Significantly higher levels of rotator cuff activation were seen during internal rotation at 90° abduction (325.0% vs 94.0–188.3%; p = 0.005–0.017). Discussion and Conclusion. This study provides a comprehensive description of muscles activation during common rotational shoulder exercises. It enables therapists to target specific muscles for rehabilitation following shoulder surgery, while minimising the activation of others. Understanding the activation profile of the shoulder girdle muscles during individual exercises forms the basis for exercise prescription and the development of tailored and individual physiotherapy protocols

Glenoid exposure is the name of the game in total shoulder arthroplasty. I can honestly say that it took me more than 5 years but less than 10 to feel confident exposing any glenoid, regardless of the degree of bone deformity and the severity of soft-tissue contracture. This lecture represents the synthesis of my experience exposing some of the most difficult glenoids. The basic principles are performing extensive soft-tissue release, minimizing the anteroposterior dimension of the humerus by osteophyte excision, making an accurate humeral neck cut, having a plethora of glenoid retractors, and knowing where to place them. The ten tips, in reverse order of importance are: 10.) Tilt the table away from operative side—this helps face the surface of the glenoid, especially in cases of posterior wear, toward the surgeon. 9.) Have multiple glenoid retractors—these include a large Darrach, a reverse double-pronged Bankart, one or two blunt Homans, small and large Fukudas. 8.) Remove all humeral osteophytes before attempting to retract the humerus posteriorly to expose the glenoid—this helps to decrease the overall anteroposterior dimension of the humerus and allows for maximum posterior displacement of the humerus. 7.) Make an accurate humeral neck cut—even 5mm of extra humeral bone will make glenoid exposure difficult. 6.) Optimal humeral position—it has been taught that abduction, external rotation, and extension is the optimal position. It may vary with each case. Therefore, experiment with humeral rotation to find the position that allows maximum visualization. This is often the position that makes the cut surface of the humerus parallel to the surface of the glenoid. 5.) Optimal retractor placement—my typical retractor placement is a Fukuda on the posterior lip of the glenoid, a reverse double-pronged Bankart on the anterior neck of the scapula, and a blunt Homan posterosuperiorly. Occasionally, a second blunt Homan anteroinferiorly is helpful, particularly in muscular males with a large pectoralis major. 4.) Laminar spreader for lateral humeral displacement—this can be helpful for posterior capsulorrhaphy or for posterior glenoid bone grafting. 3.) Maximal humeral capsular release—the release of the anterior capsule from the humerus must go well past the 6 o'clock position and up the posterior surface of the humerus. This aides in humeral exposure but also allows for more posterior displacement of the humerus during glenoid exposure. 2.) Anteroinferior capsular release or excision—extensive anteroinferior release or excision (my preference), allows for maximal posterior humeral displacement and also restores external rotation. 1.) Posterior or posteroinferior capsular release—release of the posteroinferior corner of the capsule from the glenoid results in a noticeable increase in posterior humeral retractability. In cases without substantial posterior subluxation, extensive release of the entire posterior capsule is performed

Rupture of the pectoralis major (PM) tendon is a rare yet severe injury. Several techniques have been described for PM fixation including a transosseus technique, when cortical buttons are placed at the superior, middle and inferior PM tendon insertion positions. The concern with this technique is the risk that bicortical drilling poses to the axillary nerve as it courses posteriorly to the humerus. This cadaveric study investigates the proximity of the posterior branch of the axillary nerve to the drill positions for transosseus PM tendon repair. Drills were placed through the humerus at the superior, middle and inferior insertions of the PM tendon and the distance between these positions and the axillary nerve, which had previously been marked, was measured using computed tomography (CT) imaging. This investigation demonstrates that the superior border of PM tendon insertion is the fixation position that poses the highest risk of damage to the axillary nerve. Caution should be used when performing bicortical drilling during cortical button PM tendon repair, especially when drilling at the superior border of the PM insertion. We describe ‘safe’ and ‘danger’ zones for transosseus drilling of the humerus reflecting the risk posed to the axillary nerve

The standard approach is through the deltopectoral interval. Among patients with prior incisions, one makes every effort to either utilise the old incision or to incorporate it into a longer incision that will allow one to approach the deltopectoral interval and retract the deltoid laterally. The deltopectoral interval is most easily developed just distal to the clavicle, where there is a natural infraclavicular triangle of fat that separates the deltoid and pectoralis major muscles even in very scarred or stiff shoulders. Typically, the deltoid is retracted laterally leaving the cephalic vein on the medial aspect of the exposure. The anterior border of the deltoid is mobilised from the clavicle to its insertion on the humerus. The anterior portion of the deltoid insertion together with the more distal periosteum of the humerus may be elevated slightly. The next step is to identify the plane between the conjoined tendon group and the subscapularis muscle. Dissection in this area must be done very carefully due to the close proximity of the neurovascular group, the axillary nerve, and the musculocutaneous nerve. Scar is then released from around the base of the coracoid. The subacromial space is freed of scar and the shoulder is examined for range of motion. Particularly among patients with prior rotator cuff surgery, there may be severe scarring in the subacromial space. Internal rotation of the arm with dissection between the remaining rotator cuff and deltoid is critical to develop this plane. If external rotation is less than 30 degrees, one can consider incising the subscapularis off bone rather than through its tendinous substance. For every 1 cm that the subscapularis is advanced medially, one gains approximately 20 to 30 degrees of external rotation. The rotator interval between the subscapularis and supraspinatus is then incised. This release is then continued inferiorly to incise the inferior shoulder capsule from the neck of the humerus. This is performed by proceeding from anterior to posterior with progressive external rotation of the humerus staying directly on the bone with electrocautery and great care to protect the axillary nerve. The key for glenoid exposure as well as improvement in motion is deltoid mobilization, a large inferior capsular release, aggressive humeral head cut and osteophyte removal

Following these steps will help the surgeon to gain adequate glenoid exposure, even in the most difficult cases

Introduction. We performed humeral head replacement (HHR) with smaller head for closing the cuff defect in patients of cuff tear arthropathy (CTA). And also, if the cuff defect could not close by decreasing the head size, we add muscle tendon transfer such as latissimus dorsi transfer for posterosuperior defect and pectoralis major transfer for anterosuperior defect. Aim. The purpose of this study was to investigate clinical and functional outcomes of this procedure for CTA according to Hamada-Fukuda classification. Methods. 76 shoulders in 77 patients with CTA underwent HHR based on our strategy at average age of 74 years. Hamada-Fukuda classification was classified into five categories. There were 13 type 1, 24 type 2, 26 type 3, 9 type 4, 5 type 5. Clinical outcomes (JOA score) were evaluated at an average of 25 months. Results. The average Japanese Orthopaedic Association shoulder score all improved significantly. Forward elevation improved from 57° to 146.5° in type 1, 65.5° to 132.1° in type 2, 82° to 123.9° in type 3, 90.6° to 122.1° in type 4 and 91° to 130° in type 5. Improvement of External rotation 25° in type 1, 23.1° in type 2, 10.89°in type 3, 11.3° in type 4 and −7.3° in type 5. Internal rotation similarly improved between Hamada-Fukuda classification. Conclusion. In patients of type 1 and 2, our procedure could get a good ER recovery. However, in patients of type 3, 4, and 5, functional outcomes were partly inferior to type 1 and 2. Our procedure for type 1 and 2 CTA is one of useful methods

In recently, reverse shoulder arthroplasty for rotator cuff deficient arthritis is widely used in the world. However, a high complication rate was reported and worried about long-term results after reverse shoulder arthroplasty. From 2001, we performed a novel strategy for these cases such as rotator cuff reconstruction w/ or w/o muscle transfer and a humeral head replacement with using smallest head to decrease joint volume. The aim of this study was to investigate with clinical outcomes after this surgery more than two years follow-up. Materials & methods. Fifty six shoulders underwent humeral head replacement (HHR) with or without tendon transfer for cuff tear arthropathy was able to follow-up more than two years. The mean age was 74 years (60 to 83 years). 42 cuff tear arthropathy, 6 RA, 5 re-tear after cuff repair with arthritis, and 1 arthritis after infection were included. Coracoacromial arch preserved Superior approach with preserving coracoacromial arch was used for replacement the humeral stem and head. Almost of the cases could be repaired with using a smallest head because of the height of humeral head and joint volume were decreased. However, when rotator cuff remained in irreparable condition, a latissimus dorsi tendon or a pectoralis major tendon from same shoulder was transferred for cuff reconstruction. The patients were divided by 2 groups; 36 shoulders of HHR without tendon transfer and 20 shoulders of HHR with tendon transfer. Each patient was evaluated with Japan Orthopaedic Association score (JOA score) and modified Neer's limited goals rating scale after a least 2 year of follow-up. Results. In all cases, preoperative severe pain was dramatically improved. JOA score improve from 40.2 preoperatively to 80.2 postoperatively. Twelve shoulders estimated as excellent in modified Neer's classification, 34 in satisfactory and 10 in unsatisfactory. Half of cases with RA were unsatisfactory results. Postoperative active flexion statistically improved compared to preoperative range of motion. Averaged postoperative flexion was 136 degrees (preop.;68.8) and postoperative external rotation was 28.6 degrees (preop.;13.2). However, there was no significant difference of external rotation in the HHR group between pre and postoperative evaluation. The radiographic evaluation showed four cases of glenoid erosion. One case had arthroscopic Suprascapular nerve release eight years after surgery. Conclusions. The current results were consistent with the prior studies. Our novel strategy is considered as one of useful procedure for cuff tear arthropathy. However, the case which classified with Seebauer type IIB should not be recommended

Introduction. In recently, Reverse shoulder arthroplasty (RSA) in patients with irreparable rotator cuff tear has been worldwidely performed. Many studies on RSA reported a good improvement in flexion of the sholulder, however, no improvement in external rotation (ER)and internal rotation motion (IR). Additionally, RSA has some risks to perform especially in younger patients, because high rates of complications such as deltoid stretching and loosening, infection, neurologic injury, dislocation, acromial fracture, and breakage of the prosthesis after long-term use were reported. Favard et al noted a 72% survival with a Constant-Murley score of <30 at 10 years with a marked break occurring at 8 years. Boileau et al noted caution is required, as such patients are often younger, and informed consent must obviously cover the high complication rate in this group, as well as the unknown longer-term outcome. Its use should be limited to elderly patients, arguably those aged over 70 years, with poor function and severe pain related to cuff deficiency. We developed a novel strategy in 2001, in which we used the humeral head to close the cuff defect and move the center of rotation medially and distally to increase the lever arm of the deltoid muscle. Aim. The aim of this study was to investigate clinical outcome of our strategy for younger patients with an irreparable rotator cuff tear. Materials and Methods. Eighteen shoulders (9 of male patients, 9 of female patients) of patients under 70 years old with an irreparable cuff tears and who were treated with Humeral Head Replacement (HHR) and cuff reconstruction were followed up for more than 12 months. The average age was 63.9 years (range, 58–69 years). The average follow-up period was 27.3 months (range, 12–76 months). The cuff defect was successfully closed in 8 shoulders, whereas 8 shoulders required a Latissimus Dorsi transfer; one other shoulder required a Pectralis Major transfer, and one required both Latissimus dorsi and pectoralis major transfers. Range of motion (flexion, ER), the shoulder score of Japanese Orthopaedic Association (JOA score), and complications were evaluated. Results. Shoulder pain decreased in all patients after surgery. JOA score was improved from 41.1 to 82.6 points after surgery, Flexion motion improved from 72.5 to 145.6 degrees postoperatively and ER increased from 17.5 to 37.8 degrees postoperatively. There were no complications. Conclusion. In our study, HHR using the small head of the humerus and cuff reconstruction for patients under 70 years old with an irreparable rotator cuff tear yielded favorable results as compared to RSA, especially in terms of the ER Furthermore, the advantages of our strategy is able to keep bone stock of the glenoid after surgery. If revision surgery is required, RSA can be performed. Since the patients included in our study were relatively active, long-term follow-up will be required to assess their progress

A series of 14 patients suffering from tuberculosis of the sternum with a mean follow-up of 2.8 years (2 to 3.6) is presented. All were treated with antitubercular therapy: ten with primary therapy, two needed second-line therapy, and two required surgery (debridement). All showed complete healing and no evidence of recurrence at the last follow-up. MRI was useful in making the diagnosis at an early stage because atypical presentations resulting from HIV have become more common. Early adequate treatment with multidrug antitubercular therapy avoided the need for surgery in 12 of our 14 patients.
