We previously evaluated 94 patients (96 shoulders) who underwent reverse shoulder arthroplasty using a central compressive screw with 5.0-mm peripheral locking screws for baseplate fixation and a center of rotation lateral to the glenoid as treatment for end-stage rotator cuff deficiency. The purpose of this study was to report updated results at a minimum follow-up of 10 years. Forty patients (42 shoulders) were available for clinical follow-up. In the patients available for study, implant survivorship, with the end point being revision for any reason, was 90...

Rim defects of the anterior glenoid cavity are a main reason for residual shoulder instability after traumatic dislocation of the shoulder. These defects can be the result of a glenoid rim fracture or chronic glenoid erosion after repeated shoulder dislocations. Treatment concepts for these entities are entirely different. While in the acute fracture situation glenoid rim fractures can be treated operatively or non-operatively, augmentation of the anterior glenoid for stabilization of the shoulder should be considered if the defect exceeds 15-25% of the anterior glenoid...

Glenoid rim fractures, accompanied by acute glenohumeral dislocation or subluxation usually results in persistent instability. Traditionally open reduction and internal fixation has been recommended in displaced intra-articular glenoid fractures. However, open reduction is difficult, and it may not be possible to address the associated intra-articular soft-tissue injuries. A few reports of arthroscopic-assisted fixation of these fractures have been recently published. The most anatomic method for addressing an acute glenoid rim lesion is a reduction (either open or arthroscopic) and internal fixation...

BACKGROUND: Bony deficiency of the anteroinferior glenoid rim as a result of a dislocation can lead to recurrent glenohumeral instability. These lesions, traditionally treated by open techniques, are increasingly being treated arthroscopically as our understanding of the pathophysiology and anatomy of the glenohumeral joint becomes clearer. Different techniques for arthroscopic management have been described and continue to evolve. While the success of the repair is surgeon dependent, the recent advances in arthroscopic shoulder surgery have contributed to the growing acceptance of arthroscopic reconstruction of glenoid bone defects to restore stability...

BACKGROUND: It is estimated that approximately 5% of glenohumeral instabilities are posterior. There are a number of controversies regarding therapeutic approaches for these patients. METHODS: We analyse the main surgery alternatives for the treatment of the posterior shoulder instability. We did a research of the publications related with posterior glenohumeral instability. RESULTS: There are conservative and surgical treatment options. Conservative treatment has positive results in most patients, with around 65 to 80% of cases showing recurrent posterior dislocation...

Shoulder stability depends on the position of the arm as well as activities of the muscles around the shoulder. The capsulo-ligamentous structures are the main stabilisers with the arm at the end-range of movement, whereas negative intra-articular pressure and concavity-compression effect are the main stabilisers with the arm in the mid-range of movement.There are two types of glenoid bone loss: fragment type and erosion type. A bone loss of the humeral head, known as a Hill-Sachs lesion (HSL), is a compression fracture of the humeral head caused by the anterior rim of the glenoid when the humeral head is dislocated anteriorly in front of the glenoid...

BACKGROUND: Anterior glenohumeral instability is frequently associated with anteroinferior glenoid bone defects. One original technique has been described in the literature that incorporates a J-shaped graft from the iliac crest into the anterior glenoid rim. The main goal of the present study was to evaluate the feasibility of harvesting a J-shaped graft from the acromion that corresponds to previously described dimensions. The secondary goal was to determine the ideal harvesting site...

BACKGROUND: There remains a paucity of studies examining the conversion of failed hemiarthroplasty (HA) to reverse total shoulder arthroplasty (RTSA). Therefore, the purpose of this study was to examine a large series of revision HA to RTSA. METHODS: A population of 157 patients who underwent conversion of a failed HA to a revision RTSA from 2006 through 2014 were included. The mean follow-up was 49 months (range, 24-121 months). The indications for revision surgery included instability with rotator cuff insufficiency (n = 127) and glenoid wear (n = 30); instability and glenoid wear were associated in 38 cases...

The most common procedure to address transverse glenoid fractures that are characterized by intra-articular step-off or gapping is open reduction and internal fixation. Disadvantages of open surgery are delay in regaining full range of motion, increased approach morbidity, neurovascular complications, and the need for capsulotomy, which delays healing and increases the risk of stiffness. An arthroscopically assisted fracture fixation, as described in this article, is characterized by better visualization of the glenoid articular surface and reduction of the intra-articular fragments under direct vision, which diminishes the chances of residual step-off after fixation...

The sagittal split ramus osteotomy and intraoral vertical ramus osteotomy carry the potential risk of postoperative nerve paralysis, bleeding, and fracture and dislocation of the condyle. In 1992, Choung first described the intraoral vertico-sagittal ramus osteotomy for the purpose of avoiding postoperative dislocation of the condyle. However, there is still potential for damaging the inferior alveolar nerve and maxillary artery with this technique. The authors have developed a modified technique to minimize these risks...

The glenoid fossa is involved in approximately 10% of all scapular fractures.Glenoid fossa incongruity is surprisingly well tolerated.Surgery is recommended when 20% or more of the anterior glenoid fossa is involved.Glenoid rim fractures often lead to chronic shoulder instability.Unstable glenoid neck fractures need surgical treatment and stable fractures can be treated conservatively.CT examination with 3D reformations of the glenoid fossa has improved insight into fracture morphology and fracture patterns and is very helpful for clinical decision makers...

Dislocation of the mandibular condyle from the glenoid fossa can occur in anterior, posterior, lateral, and superior directions. Posterior, lateral, and superior dislocations are rare. Superolateral dislocation is seldom encountered in clinical practice. It is generally associated with fracture of the anterior or contralateral side of the mandible. The occurrence of superolateral dislocation of the condyle hooked above the zygomatic arch with an associated fracture of the medial pole of the condyle is rare and has been reported only once in the literature...

Anders L Ekelund
Even though reverse shoulder arthroplasty is a very successful procedure, painful complications occur. During the initial postoperative years, the most common reasons for pain are instability, postoperative fracture of the acromion or spine, and periprosthetic infection. Later, aseptic loosening, with humeral loosening being more frequent that glenoid loosening, can be a source of pain and reduction in function. A careful patient history, clinical examination, plain radiographs, computed tomography and blood tests give an explanation for the pain in most cases...

BACKGROUND: The purpose of this study was to investigate the results and complications during the learning curve of reverse total shoulder arthroplasty (RTSA) for rotator cuff deficiency. METHODS: We retrospectively reviewed the first 40 cases of RTSA performed by a single surgeon. The mean age of patients was 72.7 years (range, 63 to 81 years) and mean follow-up period was 26.7 months (range, 9 to 57 months). Clinical outcomes were evaluated using a visual analog scale (VAS) for pain, the University of California at Los Angeles (UCLA) shoulder score, American Shoulder and Elbow Surgeon (ASES) score, subjective shoulder value (SSV), and active range of motion (ROM)...
