Health and safety
Published in Roger Timings, Fabrication and Welding Engineering, 2008
These are caused by internal bleeding that seeps through the tissues to produce the discoloration under the skin. Bruising may develop very slowly and appear hours, even days, after injury. Bruising that develops rapidly and seems to be the main problem will benefit from first aid. Caution, bruises may indicate deeper injury. Seek professional advice.

Complications of using the lateral arm device are similar to that of any breast biopsy including pain, infection, hematoma, inadequate sampling/undersampling, and bruising, all of which are similar in degree to the standard approach [10]. One potential disadvantage lies in the ability to provide adequate anesthesia in larger breasts. It is recommended to use a 18 G, 9 cm length spinal needle when placing local anesthetic; however, it is not the same length as the biopsy needle and in some patients is too short to reach the target site and provide appropriate anesthesia [10]. To ensure appropriate depth for numbing, one should look at the Z depth either by measuring it from the edge of the breast on the side of planned entrance to the lesion or by allowing the software to calculate the Z at the time of biopsy. If either of these calculations is greater than 9 cm, then proper anesthesia may not be obtained. Though clip and seed migration still occurs in the standard approach, it is thought to decrease with the lateral approach though still occurs (Figure 4). Many device companies state that the lateral approach decreases migration due to decreased accordion effect from the clip being placed in the same direction as the compression [10].

Figure 1 shows the injured body regions by age group for NASS-CDS and FARS cases. Case occupants in NASS-CDS sustained an average of 2.5 AIS 3+ injuries in an average of 1.5 body regions. Six of these occupants, all ages 64 years or older, sustained fatal chest injuries in noncatastrophic crashes. Injury information varied widely in FARS cases, with autopsy or hospital injury records available for 18 cases and other medical information available for another 19 cases. Comprehensive injury information was available for some cases, but others provided more generic information such as “blunt force trauma” or “neck injury.” Standardized injury severity coding such as AIS codes was not available for any FARS cases. However, documented superficial injuries such as chest bruising or extremity fractures generally consistent with AIS 1 or 2 injuries were not included in injury counts.
Analysis and comparison of lateral head impacts using various golf discs and a Hybrid III head form

The high-speed video showed a larger contact patch with putters, than with drivers (Figures 4 & Figures 5). While the risk of structural head and brain injury was found to be low in both cases, there does exist the possibility that the stiffer drivers could cause more soft tissue injury such as bruising or laceration. Further study is warranted in this regard.
