We have examined 167 patients who had a hemiarthroplasty for three- and four-part fractures and fracture-dislocations of the head of the humerus in a multicentre study involving 12 Austrian hospitals. All patients were followed for more than a year. Anatomical healing of the tuberosity significantly influenced the outcome as measured by the Constant score and subjective patient satisfaction. Wi...

BACKGROUND Complex proximal humeral fractures are very difficult to treat particularly in patients older than 65 years with an osteoporotic bone and tuberosities compromised. The goal of this paper is to evaluate radiological outcomes at mid-term follow-up of proximal humerus fractures treated with reverse shoulder arthroplasty using a dedicated fracture stem. MATERIALS AND METHODS The study ...

Management of proximal humerus fractures with hemiarthroplasty has been shown to yield unpredictable and inconsistent outcomes. Risk factors for clinical failure following hemiarthroplasty include postoperative tuberosity failure, advanced age, female sex, osteoporosis, and inability or unwillingness to participate in the extensive rehabilitation required. In this difficult-to-manage injury, re...

Results of hemiarthroplasty for complex four-part proximal humerus fractures in the elderly have been unreliable. Although patients often achieve pain relief, return of above-shoulder level function can be challenging, because tuberosity nonunion, malunion, and/or resorption is quite common. The reverse shoulder replacement has been advocated as a reliable alternative for these patients. Prelim...

Understanding of the anatomy of the proximal part of the fifth metatarsal helps to differentiate the types of fractures and recognize variables affecting healing. The proximal part of the fifth metatarsal includes the head, the metaphyseal region, the tuberosity and the proximal part of diaphysis, with the tuberosity being the most proximal and plantar structure. The proximal part of the 5th me...

There is a paucity of orthopaedic literature describing avulsion of the ischial tuberosity, but its spontaneous healing does not seem to have been reported to-date. This article describes the case of a young football player who suffered an avulsion fracture of the ischial tuberosity while kicking vigorously next to the ball during a football match. The diagnosis was not made at the time of trau...

INTRODUCTION Caudal cruciate ligament injury can be a complication following tibial plateau leveling osteotomy (TPLO) (Slocum und Slocum, 1993) especially if the post-operative Tibial Plateau Angle (TPA) is less than 5 degree. We describe a case of negative TPA associated with partial cranial and caudal ligament rupture treated with a center of rotation of angulation (CORA) based cranial tibial...

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 total shoulder arthroplasty (RTSA) is increasingly used for the treatment of complex proximal humerus fractures and fracture sequelae. In 2021, half a dozen models stems are commercially available, reflecting its growing utility management. Prosthesis designs, bone grafting tuberosity fixation techniques have evolved to allow better more reliable tuberosities bony ingrowth. Patients wit...

Avulsion fracture of the tibial tuberosity is an uncommon lesion generally seen in adolescents. Intra-articular lesions combined with a tibial tuberosity fracture reported in the literature are; 3 patellar tendon ruptures, 2 anterior cruciate ligament tears, 2 medial collateral ligament tears, 2 medial meniscus tears, one arcuate ligament tear, and one lateral meniscus tear. In our study, both ...
