Abstract
INTRODUCTION The aim of this study was to find a convenient technique to evaluate the location of the radial nerve (RN) with reference to the deltoid tuberosity (DT). MATERIALS AND METHODS Sixty-eight upper extremities, embalmed using a modified version of Thiel's method, were included in the study. The interval between the tip of the greater tubercle of the humerus and the distal tip of the lateral humeral epicondyle (LE) was defined as humeral length (HL). The most prominent point of the DT was used as the point of reference. Through this point, a horizontal reference line which met the humeral axis at the dorsal side of the humeral shaft was simulated. The longitudinal distance between the crossing point of the horizontal line and the humeral axis and the RN was measured (distance 1). The interval between the intersection point and the reference point at the DT was measured (distance 2). Data were evaluated in centimeters. RESULTS For the whole sample, the HL averaged 31.0 cm (SD: 2.3; range 26.2-36.9). Distance 1 averaged 2.2 cm (SD: 0.3; range 1.6-3.1), and distance 2 averaged 1.2 cm (SD: 1.0; range 0-2.8). The HL was larger in the male group when compared to females (p < 0.001; males mean: 32.2 cm; females mean 29.5 cm). There was no difference regarding distance 2 (p = 0.59; males mean: 1.2 cm; females mean: 1.3 cm) between the sexes. Distance 1 was significantly (p = 0.02) larger in the male group (mean: 2.3 cm) when compared to females (mean: 2.1 cm). Concerning sides, there were no differences regarding all evaluated parameters (HL: p = 0.6; Distance 1: p = 0.6; distance 2: p = 0.8). CONCLUSIONS This study provides an easily applicable technique to localize the RN with reference to the DT.

Abstract
Radial nerve injuries are among the most common major traumatic peripheral nerve injuries. Recent literature has updated our knowledge of aspects ranging from radial nerve anatomy to treatment options. Observation and tendon transfers were, and still are, the mainstays of management. However, the improved outcomes of nerve repair even 5 months after injury have changed the treatment algorithm. Nerve repair techniques using conduits, wraps, autograft, and allograft allow tension-free coaptations to improve success. Nerve transfers have evolved to allow a more anatomic recovery of function if used in a timely manner. This review offers an update on radial nerve injuries that reflects recent advances.

Humerus shaft fracture associated with traumatic radial nerve palsy: An international survey among orthopedic trauma surgeons from Latin America and Asia/Pacific.

Abstract
PURPOSE The purpose of this article is to explore the real-life practice of clinical management of humeral shaft fracture associated with traumatic radial nerve palsy among orthopedic trauma surgeons. METHODS Two hundred seventy-nine orthopedic surgeons worldwide reviewed 10 real cases of a humeral shaft fracture associated with traumatic radial nerve palsy answering two questions: (1) What treatment would you choose/recommend: nonoperative or operative? (2) What are the reasons for your decision-making? The survey was developed in an online survey tool. All participants were active members from AOTrauma International. RESULTS Two hundred sixty-six (95.3%) participants were from Latin America and Asia/Pacific. One hundred sixty-two participants (58.1%) had more than 10 years in practice and 178 (63.8%) of them did trauma as the main area of interest. One hundred fifty-one (54.1%) participants treated less than three humeral shaft fractures a month. Traumatic radial nerve palsy was the main reason (88.4%) for surgeons to recommend surgical treatment. Open reduction and internal fixation (ORIF) or percutaneous fixation of the fracture associated with acutely explore of radial nerve was the first option in 62.0% of the cases. A combination of morphology and level of the fracture and the presence of the radial nerve palsy was the most suggested reason to surgically treat the humerus fracture. The main isolated factor was the morphology of the fracture. CONCLUSION Our survey highlight the tendency for a more aggressive management of any humeral shaft fracture associated with a traumatic radial nerve palsy, with surgeons preferring to use ORIF with acute exploration of the radial nerve. Nonsurgical management was the less chosen option among the 279 respondents. Fracture morphology, level of the fracture, and the presence of the radial nerve palsy were most influential for guiding their treatment.
