The treatment of proximal humeral bone loss with its associated pain and loss of function continues to be a challenge for the orthopaedic surgeon. Current options for this condition include hemiarthroplasty or total shoulder arthroplasty with the addition of bone grafting. Unfortunately, due to residual instability, these options have not given the desired results. Reverse shoulder arthroplasty...

BACKGROUND Proximal humeral fractures are common osteoporotic fractures. Most proximal humeral fractures are treated non-surgically, although surgical treatment has gained popularity. The purpose of this study was to determine changes in the surgical treatment of proximal humeral fractures in Finland between 1987 and 2009. METHODS The study covered the entire adult (>19 y) population in Finla...

Successful total shoulder arthroplasty is, in part, dependent on anatomic reconstruction of the glenohumeral joint. The purpose of this study was to evaluate the post-operative anatomy of total shoulder arthroplasty with an anatomic implant design in patients with primary glenohumeral osteoarthritis and compare it to published normative anatomic measurements. Fifty-one patients (56 shoulders) w...

INTRODUCTION Total humeral replacement is used to reconstruct the upper limb after tumour resection, while in cases of complex revisions for non-oncological reasons, using tumour prosthesis implants will lead to an otherwise avoidable further bone resection and violation of the surrounding tissues. This report describes a design evolution in three non-oncological cases, where a total humeral re...

We undertook a prospective MRI study to measure the retroversion of the humeral head in 33 consecutive infants with a mean age of 1 year 10 months (3 months to 7 years 4 months) who had an obstetric brachial plexus lesion (OBPL). According to a standardised MRI protocol both shoulders and humeral condyles were examined and the shape of the glenoid and humeral retroversion determined. The mean h...

OBJECTIVE To assess imaging parameters related to the morphology of the glenohumeral joint in children with unilateral brachial plexus birth palsy (BPBP), in comparison with those obtained for healthy shoulders. MATERIALS AND METHODS We conducted a retrospective search for cases of unilateral BPBP diagnosed at our facility. Only patients with a clinical diagnosis of unilateral BPBP were inclu...

OBJECTIVE To obtain anatomical data on intertubercular sulcus of humerus, evaluate the correlation between intertubercular sulcus and retroversion angle of humeral head, to guide the positioning of torsion angle of prosthesis during total shoulder arthroplasty and provide references for shoulder prosthesis design. METHODS Using a Siemens Ultrahigh speed 64- rows multi-slices spiral CT scanner...

An anatomic study was conducted on 49 dried cadaveric humeri and 24 dried cadaveric scapula to ascertain the variability of the following parameters: humeral neck angle, humeral head retroversion, humeral head medial offset, humeral head posterior offset, humeral head diameter glenoid height, glenoid width, and the glenoid height to width ratio. For verification purposes, the results of this st...

BACKGROUND A Hill Sachs lesion is a posterior-superior bony defect of the humeral head caused by a compression of the hard glenoid rim against the soft cancellous bone in the context of an anterior instability episode. The presence of these humeral defects increases with the number of dislocations and larger lesions are associated with a greater chance of development of recurrent instability an...

Introducción: el enclavijamiento endomedular (EE) es una opción terapéutica para fracturas de la diáfisis humeral; sin embargo, algunos pacientes tratados con EE desarrollan signos pinzamiento subacromial y disminución fuerza en movimientos flexión abducción. Objetivo: evaluar impacto hombro del uso anterógrado tratamiento humeral términos dolor, funcionalidad subacromial. Metodología: estudio ...
