Summary
Proximal interphalangeal (PIP) joint fracture dislocations are rare but can limit motion. Interposition arthroplasty may offer better range of motion outcomes compared to other surgical treatments.
Area of Science:
- Orthopedic Surgery
- Hand Surgery
- Traumatology
Background:
- The proximal interphalangeal (PIP) joint is the most frequently dislocated joint in the hand.
- PIP joint injuries, particularly fracture dislocations, present unique management challenges.
Purpose of the Study:
- To review the literature and report on the experience of treating PIP joint fracture dislocations.
- To evaluate the outcomes of various treatment modalities for PIP joint fracture dislocations.
Main Methods:
- Systematic review of the literature.
- Retrospective and descriptive study of 13 patients treated between 1991 and 2007.
- Analysis of treatment approaches including ORIF, OR with blocking pins, and interposition arthroplasty.
Main Results:
- Factors negatively impacting range of motion included patient age, delayed treatment, combined approaches, and extension-blocking pins.
- Interposition arthroplasty demonstrated a better range of motion compared to other methods.
- Mean follow-up was 4.8 months for 8 patients with recorded range of motion data.
Conclusions:
- PIP joint fracture dislocations are rare with diverse treatment options and variable functional outcomes.
- Limited flexion and extension are common sequelae following PIP joint fracture dislocations.
- Interposition arthroplasty may be a favorable option for improving range of motion.

Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
Functional Classification of Joints
Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

Structural Joints: Fibrous Joints
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

Bones of the Upper Limb: Radius
The radius is longer of the two bones that make up the human antebrachium or forearm. At the proximal end, the radius articulates with the capitulum of the humerus and the radial notch of the ulna to form the elbow joint. At the distal end, the radius articulates with the ulna via the ulnar notch, forming the distal radioulnar joint. Distally, the radius also attaches to the carpal wrist bones (scaphoid and lunate) to form the radiocarpal joint.
The radius has a nail-shaped head, and a short...

Structural Joints: Synovial Joints
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...
