When a pin is too tight to remove by hand, the correctly sized parallel pin punch can be employed to drive it loose.

Wad Punch - Have interchangeable heads and are used to cut accurate circles into textile materials. They can even be used on thin metal to make washers. Trunk rotation and rear leg extension are observed to be the greatest contributors to punch force in advanced boxers, at 37.42% and 38.46% respectively; whereas, arm extension only contributes 24.12% (Filimonov et al., 1985; Table 1). Additionally, well trained junior boxers are observed to make a greater contribution to punch force at the shoulder than in the trunk and legs than elite boxers (Dinu & Louis, 2020). Though, the same study did identify front foot GRF (ground reaction force) as a greater contributor to RHSP force than the rear leg (Dinu & Louis, 2020). Furthermore, when the trunk and lower body are fatigued, a significant decrease in punch force across all punch techniques has been observed (Dunn et al., 2021). Thus, corroborating the findings of Filimonov et al. (1985) and Dinu and Louis (2020) and demonstrating the importance of force development in the rear leg and trunk.

After a thorough evaluation, the diagnosis usually falls within one of these common injury categories. The symptoms of hand injuries can vary depending on the type of injury, how the injury occurred (mechanism), depth, severity, and location.Some hand lacerations are self-inflicted. After wound treatment, these patients should be referred to a psychiatric specialist.

Injuries to the hand causing the following symptoms generally require emergency medical attention at a hospital's emergency department. Furthermore, sport specific drills can be used to emphasise landing with a rigid front leg and leading with the pelvis before rotating the trunk when performing the RHSP. This will allow a larger braking force to be generated and increase the stretch shortening effect between the pelvis and trunk, resulting in an increase in RHSP force (Cabral et al., 2010; Cheraghi et al., 2014). Additional resources Splinting describes any method used to keep the injured hand or finger from moving. The doctor may place an injured hand or finger against a solid, stiff object but not inside a cast. With a splint, the injured area is immobilized yet still has room to swell. A cast does not allow for swelling, so the injury may be cast a few days after swelling has decreased. Spring Pin Punch - Spring pin punches are used for removing roll pins, a type of mechanical fastener. For this reason, spring pin punches are also called roll pin punches and are specially shaped to remove roll pins without causing damage or becoming jammed. These injuries can be devastating to the hand and the patient. Reattaching (replantation) is difficult, and even if successful may, cause long-term complications with pain and infection. Situations, when a surgeon may attempt replantation, are amputation involving a child, thumb amputation, or amputation of multiple fingers or the entire hand.Intricate in design and function, the hand is an amazing work of anatomic engineering. Form follows function in the hand; therefore, any injury to the underlying structures of the hand carries the potential for serious handicap. To reduce this risk, even the smallest hand injuries require proper medical evaluation. Tong-Iam, R., Rachanavy, P., & Lawsirirat, C. (2017).
