Metastases to bone are the most frequent cause of destructive lesions to the skeleton in adults . The tumours that are most likely to metastasize to bone are prostate (32%), breast (22%), kidney (16%), lung and thyroid. The typical distribution of metastatic lesions are to the spine, ribs, pelvis, and proximal limb girdles. The humerus is the second most common site for long bone metastases, behind only the femur in its frequency of involvement . It represents the 20% of all bony metastases. We present a clinical case of an 86 yo woman with a previous diagnosis of myofibroblastic sarcoma of the maxillaris who suffers a pathological fracture of the humeral shaft secondary to metastasis and was misdiagnosed and treated for a typical humeral fracture using and intramedullary pinning (Hackethal technique), producing the progression of the disease within the humeral shaft...

Osteoporosis is related to more than 2 million fractures and $19 billion in healthcare costs each year (). A fragility fracture (FF) is a low-energy fracture of the distal radius, proximal humerus, ankle, or proximal femur (hip) from minimal trauma such as a fall from a standing height. In addition to cost, FFs often result in the loss of independence and productivity (). In 2015, our orthopaedic unit received the first certification ever awarded for FFs. Fragility fracture certification is a new certification demonstrating that a healthcare facility complies with national patient care standards and uses evidence-based practice guidelines to deliver quality outcomes...

After wide excision of proximal humeral bony malignancy, prognosis-based reconstruction was performed at Taipei Veterans General Hospital. Bone prosthesis composite (BPC) was carried out among patients with a favored prognosis, while cement-spacer prosthesis composite (CSPC) was preserved for patients with poor prognosis. The aim of our study is to compare the clinical outcomes between the BPC and CSPC reconstruction procedures. From January 2000 to December 2014, we retrospectively reviewed the clinical outcomes of 34 patients who underwent shoulder hemiarthroplasty following wide excision of a malignant lesion of the proximal humerus, 15 of whom were treated with a BPC reconstruction and 19 cases were treated with a CSPC reconstruction...

PURPOSE: Implantation of a reverse total shoulder arthroplasty (rTSA) places the axillary and suprascapular nerves at risk. The aim of this anatomic study was to digitally analyse the location of these nerves in relation to bony landmarks in order to predict their path and thereby help to reduce the risk of neurological complications during the procedure. METHODS: A total of 22 human cadaveric shoulder specimens were used in this study. The axillary and suprascapular nerves were dissected, and radiopaque threads were sutured onto the nerves without mobilizing the nerves from their native paths...

PURPOSE: Carbon-fibre reinforced polyetheretherketone (CFR-PEEK) plates have recently been introduced for proximal humerus fracture treatment. The purpose of this study was to compare the locking screw-plate interface stability in CFR-PEEK versus stainless steel (SS) proximal humerus plates. METHODS: Locking screw mechanical stability was evaluated independently in proximal and shaft plate holes. Stiffness and load to failure were tested for three conditions: (1) on-axis locking screw insertion in CFR-PEEK versus SS plates, (2) on-axis locking screw insertion, removal, and reinsertion in CFR-PEEK plates, and (3) 10-degree off-axis locking screw insertion in CFR-PEEK plates...

BACKGROUND: There are several options for reconstruction of proximal humerus resections after wide resection for malignant tumors in children. The clavicula pro humero technique is a biologic option that has been used in the past, but there are only scant case reports and small series that comment on the results of the procedure. Because the longevity of children mandates a reconstruction with potential longevity not likely to be achieved by other techniques, the clavicula pro humero technique may be a potential option in selected patients...

The high rate of required reoperation indicates that treatment of fragility fractures at the proximal humerus still remains a major challenge in trauma surgery. Improved fixation approaches are needed. Several limitations of the conventional implant development process involving experimental testing could be overcome by using computer models that would allow systematic and efficient analyses. However, such models require experimental validation. This study investigated if linear elastic continuum finite element (FE) models can predict experimental fatigue failure in locking plate fixation of osteoporotic proximal humerus fractures...

Proximal humerus fractures (PHFs) are common injuries seen mostly in elderly patients. Although nonoperative management is acceptable for most patients, surgical fixation is often advocated for younger patients or active, elderly patients with reconstructable fractures. A variety of fixation methods exist: percutaneous pinning, open reduction and internal fixation with locking plates, and intramedullary nailing are viable options. Modern intramedullary nails serve as excellent options for the fixation of many operative PHFs...

PURPOSE: Bilateral posterior fracture dislocation is a rare injury commonly associated with seizures. When the humeral head defect (reverse Hill-Sachs lesion) is between 20% and 45%, operative fixation using a modified McLaughlin procedure is recommended. This video demonstrates a case of bilateral posterior fracture dislocation after a drug-induced seizure treated with a modified McLaughlin procedure. METHODS: The original McLaughlin procedure involved transfer of the subscapularis tendon from the lesser tuberosity to the reverse Hill-Sachs defect...

BACKGROUND: Anatomic reduction and placement of an inferior calcar screw are strategies to prevent fixation failure in proximal humerus factures. Optimal position of the calcar screw remains unknown. METHODS: There were 168 shoulders (68.5% female; average age, 63.6 ± 11.5 years) that underwent open reduction and internal fixation of a displaced proximal humerus fracture involving the surgical or anatomic neck. Univariate and multivariate analyses were performed on preoperative clinical, preoperative radiographic, and postoperative radiographic variables to determine association with fixation failure...
