The functional outcome of hemiarthroplasty in displaced proximal humeral 3- and 4-part fractures or fracture dislocations in elderly patients is frequently unpredictable and depends on the position of the prosthesis and tuberosity fixation. Reverse shoulder arthroplasty represents an alternative in elderly patients. The purpose of this study was to report the results of a retrospective series o...

Dissociation of a Morse taper arthroplasty is an uncommon occurrence, especially in the shoulder, reported in only one publication in the English literature.1 In response to reported dissociations of Morse taper modular humeral components, Blevins et al. identified conditions that would interfere with the Morse taper interface strength. The relevant cases were reported only in a single componen...

The reverse prosthesis has become a treatment of choice for glenohumeral osteoarthritis in a cuff-deficient shoulder. It allows restoration of mobility despite the loss of rotator cuff function. Hemiarthroplasty, the historical standard of care for proximal humeral fractures requiring replacement, fails most commonly because of tuberosity nonunion. Therefore, in the face of poor bone quality, t...

Reverse shoulder prosthesis has become one of the most often used prosthetic implants in shoulder replacement surgery. It has a wide spectrum of indications, starting from comminuted humeral fractures and posttraumatic arthritis to arthritis caused by the rotator cuff loss. Its application at our hospital began in 2004, at first in few specific cases and with time in ever growing number of pati...

BACKGROUND To investigate the short and medium term outcomes of bone defect reconstruction with bone cement prosthesis after clavicle malignancies resection. METHODS A total of 5 clavicular malignancy patients experienced bone cement prosthesis reconstruction after subtotal claviculectomy were enrolled the study from January 2005 to May 2012. Musculoskeletal Tumor Society score (MSTS), Visual...

The non-Hodgkin lymphoma (NHL) is one of the most common shoulder neoplasms, especially the diffuse large B cell lymphoma (DLBCL). We report a rare case of shoulder pain in a 80-year-old man presenting with a six-month history of continuous severe pain to the right shoulder. Routine laboratory studies were normal. Shoulder MRI showed an in-growing inhomogeneous lesion in the anteromedial aspect...

abstract  background: chronic neglected dislocation of the shoulder joint can be defined as a neglected dislocation for more than a 3 week period. however, it has been shown that the negligence could range from a 24 hour period to 6 months1. depending on age, signs, symptoms, etiology and types of dislocation, conservative treatment or surgical intervention could be considered.  methods: in thi...

One of the most difficult aspects of shoulder arthroplasty is retroversion. The ideal angle is about 30 of posterior rotation of humeral head with regard to the frontal plane so that the humeral head squarely faces the glenoid surface in the resting position.The axis, lateral epicondylemedial epicondyle is often taken as reference and serves as landmark in many arthroplasty instrumentation. [1,...

BACKGROUND Several stemless shoulder implants are available on the market, but only a few studies have presented results with sufficient mid- to long-term follow-up. The present study evaluated clinical and radiologic outcomes 9 years after anatomic stemless shoulder replacement. METHODS This is a prospective cohort study evaluating the stemless shoulder prosthesis since 2005. Anatomic stemle...

Erratum After the publication of the article [1] is was brought to our attention that the title was incorrectly given as “High incidence of periprosthetic joint infection with propionibacterium acnes after the use of a stemless shoulder prosthesis with metaphyseal screw fixation a retrospective cohort study of 241 patients propionibacter infections after eclipse TSA”. The correct title is “High...
