BACKGROUND In recent years there has been an increasing interest in high tibial osteotomy (HTO) to treat patients with chronic knee instability due to posterolateral corner (PLC), posterior cruciate ligament (PCL), and anterior cruciate ligament (ACL) insufficiencies with concurrent malalignment in the coronal and/or sagittal plane. PURPOSE To perform a systematic review of the use of HTO for...

The elbow is a difficult joint to treat because of the subtle nuances involved in pathology, examination, and treatment. Patients experiencing the sequelae of recurrent elbow instability can lose substantial function in the affected upper extremity. Elbow instability comprises a wide spectrum of diseases, ranging from valgus instability in the throwing athlete to traumatic recurrent rotatory in...

Ehlers-Danlos syndrome (EDS)-hypermobility type (HT) is considered to be the most common subtype of EDS and the least severe one; EDS-HT is considered to be identical to the joint hypermobility syndrome and manifests with musculoskeletal complaints, joint instability, and soft tissue overuse injury. Musculoskeletal complaints manifest with joint pain of non-inflammatory origin and/or spinal pai...

Due to its exposed position, the MCP joint of the thumb is particularly vulnerable to dislocations and fracture dislocations. Depending on the direction of the injuring force, injuries to the ulnar, radial, and volar aspect of the joint can occur. If high-grade lesions are not identified and treated appropriately during their acute phase, marked instability with associated long-term disability ...

Sternoclavicular dislocations account for less than 5% of all dislocations of the scapular belt. Most cases of anterior dislocation of the sternoclavicular joint do not present symptoms. However, some patients may develop chronic anterior instability and remain symptomatic, and surgical treatment is indicated in these cases. There is a scarcity of reports in the literature relating to reconstru...

Although there are many studies demonstrating increased trunk activation under unstable conditions, it is not known whether this increased activation would translate into meaningful trunk strength with a prolonged training program. Additionally, while balance-training programs have been shown to improve stability, their effect on specific joint proprioception is not clear. Thus the objective of...

OBJECTIVE To discuss the role of the sensorimotor system as it relates to functional stability, joint injury, and muscle fatigue of the athletic shoulder and to provide clinicians with the necessary tools for restoring functional stability to the athletic shoulder after injury. DATA SOURCES We searched MEDLINE, SPORT Discus, and CINAHL from 1965 through 1999 using the key words "proprioceptio...

Injuries to the proximal interphalangeal joint (PIPJ) of the fingers are common. They occur most often following an axial impact on an extended finger. Fractures of the proximal interphalangeal joint include a wide spectrum of injuries, from stable avulsion fractures to complex fracture-dislocations. Stability of the joint is paramount in determining the appropriate treatment, which should aim ...
