Application of humeral nail in the treatment of humeral shaft fractures is a relatively novel method of fracture fixation. Its application at Clinical Department of Traumatology, Sestre milosrdnice University Hospital Center began in 2001. The operative procedure should be performed using a minimally invasive technique without fracture opening in order to maintain optimal conditions for fracture healing including hematoma management. However, in everyday practice it is often impossible to obtain satisfactory fracture reduction using the closed procedure, so open reduction and additional fixation with wires or screws are mandatory. Over the last 14 years, fixation of fractures with the locking nail was performed in more than 400 patients. Cases of pseudarthrosis and pathological fractures were also managed successfully. There were more female patients. The mean time from injury to surgery was 2.4 days. Surgery was performed immediately upon admission to the emergency service whenever possible. This study comprised 234 patients with humeral shaft fractures treated with the humeral nail (antegrade insertion was applied in 103 and retrograde in 131 patients). The aim of the study was to stress out the complexity of appropriate operative treatment of humeral shaft fractures using intramedullary fixation, as well as the importance of proper reduction and stable fixation.

Single-stage intramedullary nailing for patients with multiple concurrent long-bone fractures in a low-resource setting: what factors contribute to prolonged operative duration?
Eur J Trauma Emerg Surg

Bowen University Teaching Hospital, P. O. Box 15, Ogbomoso, Oyo State, Nigeria.
Purpose: To investigate the factors that prolonged the operative duration (OD) in patients who underwent single-stage locked intramedullary nailing of their multiple concurrent long-bone fractures (LBFs) using Surgical Implant Generation Network (SIGN) nails.
Methods: Forty-nine patients who fulfilled the inclusion criteria were enrolled prospectively over 8½ years. Data collected included age, sex, injury mechanism and severity, fracture characteristics, nail types and diameter, OD, fracture-to-fixation time, length of hospital stay (LOS), functional outcomes and complications.
Proximal humeral fractures (PHF), ranking as the third most common osteoporotic fractures, pose a significant challenge in management. With a rising incidence in an aging population, controversy surrounds surgical versus nonoperative treatments, particularly for displaced 3- and 4-part fractures in older patients. Locking plates (LP) and proximal intramedullary nails (PHN) are primary choices for surgical intervention, but both methods entail complications.

Department of Orthopedics, Beijing Chaoyang Hospital, Capital Medical University, 8 Gongren Tiyuchang Nanlu, Chaoyang District, Beijing, 100020, China.
Background: Finite element analysis (FEA) could advance the understanding of fracture fixation and guide the choice of surgical treatment. This study aimed to compare two internal fixation methods in the treatment of displaced proximal humeral fracture (PHF) through FEA.
Methods: Three-dimensional FEA model based on the left shoulder joint of a 67-year-old female patient with PHFs and osteoporosis was adopted, in order to analyze the fixation effect and load stress distribution of internal fixation plates with open reduction and intramedullary nails without opening the fracture in the treatment of Neer III-VI PHF.
Background Proximal humerus fractures (PHFs) are often injuries that occur in the field of orthopedics and can either be treated conservatively or operatively. The PHILOS (Proximal Humerus Interlocking System) and the proximal humerus nail (PHN) are the commonly used operative techniques. Objectives The objective of this study is to analyse the functional outcome of the PHILOS (Proximal Humerus Internal Locking System) and the PHN (Proximal Humerus Nail) in proximal humerus fractures.

The purpose of this study was to establish typical dose values at orthopaedic operating rooms of the Larnaca General Hospital (LGH). Kerma area product (KAP), fluoroscopy time (FT) and cumulative air-kerma (K) measurements were collected for 821 patients who underwent common and reproducible trauma surgery over a five-year period, with three mobile C-arm systems; two equipped with an image-intensifier and one with a flat-panel detector. Dose indices were automatically extracted from radiation dose structured reports or DICOM meta-data files archived in the PACS, using custom-made software.
