Fractures and musculo-skeletal injury to the musculo-skeletal system can result in damage to bones, joints, muscles and tendons. 
fracture is a break bone continuity . Fracture basis on aetiology like external environment, displacement of the fracture,  pattern of the fracture.

In addition, the neurovascular bundle of the limb may be damaged. This section will outline the broad principles used in the diagnosis and management of these injuries. These principles can be applied, with suitable modifications, in the management of any musculoskeletal injury

⧪PHYSIOLOGY OF MUSCULOSKELETAL REPAIR

Bone Fracture and Healing 
The ability of any given bone to resist applied forces depends on many factors, including the bone’s strength or density, the direction and rate of loading, the type of load applied, and the capability of surrounding muscles and ligaments to absorb part of the injury force.
Different loading modes result in different fracture patterns. For example........

➧Transverse fracture loading the bone in tension typically 
➧Spiral fractures whereas torsional forces produce . 
➧Short oblique fractures - are caused by axial (compressive) loading
➧Long oblique fracture - results from a combination of axial and rotational load.
➧A Y-shaped butterfly fracture -  pattern indicates a bending force

 Cortical bone and cancellous (trabecular) bone have different mechanical properties; however, both cortical and cancellous bones are stronger when loaded in compression compared with tension. The magnitude of the load required to fracture a bone is reduced in certain disease states that make bone weaker or more brittle, such as osteoporosis, metabolic bone diseasetumor, or infection
