Locking plates or “internal external fixators” were introduced to orthopaedic practice in the late 19th century and their popularity has significantly increased in recent years in human orthopedic surgery led by the AO group who began popularizing them in the 1960s.
It is essential that the plate-bone construct withstand physiological loads to allow for the fracture to unite before the plate ultimately fails. It is also essential that the bone blood supply is minimally disrupted by surgical dissection and there is as little periosteal contact between the bone and the plate as possible.
Conventional non-locked plates are generally successful however they do display certain limitations, particularly in the frequently common occurrence of an osteoporotic patient. Other factors which cause concern in the setting of conventional plates are cancellous bone, comminution or pathological bone as they do not allow for sufficient purchase of bone to generate the required torque to achieve stability.
There are 2 broad groups of modern locking plates: fixed angle and variable angle plates with some implants giving you both options at each screw hole. This gives the surgeon the optimal opportunity to gain purchase in bone with difficult fracture patterns. [...]
