Strong has suggested an interesting dynamic PIP joint extension block splint using 2 bent aluminum foam-backed splints secured to the dorsal proximal and middle phalanges.

Dorsal extension block splint. Dorsal block extension block splint thermoplast splint finger splint PIP. Extension block splinting of the proximal interphalangeal PIP joint is useful for the treatment of some PIP joint fractures and dislocations or as part of post-operative rehabilitation such as protection of the PIP joint volar plate repair. Extension block splinting EBS at the proximal interphalangeal joints of the fingers is a common technique for both primary treatment of reduced dorsal dislocationsfracture-dislocations at that joint and as a rehabilitation method following open reduction of such injuries.

It is seldom realized th. Extension block splinting EBS at the. PIP Joint Dorsal Extension-Block Splint.

Larger middle phalangeal volar avulsions with potential for dorsal subluxation. Reduced stable PIP joint dorsal dislocations Source. Bret Hample Posted By Jonah Latsky on December 29 2019.

COMMENT AND OR SUGGEST A VIDEO. Splint applied to dorsal surface of affected finger from distal finger nail to proximal Metacarpal s. Tape the splint to finger over the MCP joint and the proximal phalanx.

PIP should be able to freely flex but limited in extension by the splint position. There are a variety of treatment options for dorsal fracture-dislocations of the proximal interphalangeal PIP joint. Extension block splinting is a form of nonoperative management that focuses on maintaining an acceptable reduction of the PIP joint while allowing for adequate safe motion.

By maintaining a reduced joint the extension block. A dorsal block splint is used for displaced or open fractures repaired with surgical stabilization. This splint is intended to relax the tensions over the fracture and is used to facilitate movement Freeland et al.

PIP extension block splinting has a role for certain injuries and certain post-operative protocols. A reliable splint design that is easy to manage makes this treatment choice more attractive to the surgeon and the patient. Proximal Interphalangeal Joint Extension Block Splint.

Treatment by splinting is also associated with complications such as skin maceration slough and dorsal tender prominences. The extension block pinning method as described by Ishiguro in 1988 provides a stable fixation without the complications of open surgical methods. Several studies have shown the advantages of extension block.

Push the finger through the slit of the splint in a downward direction. Fold the lateral edges inwards at the level of the palmar section. Mark the joint axis and align the lateral extension spring accordingly.

Heat the wings I and II and fold them upwards while the spring is held in place. Dorsal fracture-dislocation of the PIP is an unstable lesion and can compromise digitopalmar grip. Stabilization should not be obtained at the expense of painful stiffness.

Extension-block pinning a simple and reproducible technique provides stabilization and early movement of the PIP joint giving highly satisfactory functional results. Download scientific diagram Dorsal extension-block splint. Indications and Methods Management of a wide variety of musculoskeletal conditions requires the.

Dorsal Extension-Block Splint. Middle phalanx volar avulsion Fracture larger avulsions with risk of dorsal subluxation PIP joint dorsal dislocations reduced and stable Images. Splint applied to dorsal surface of affected finger from distal finger nail to proximal.

Jim Wagner OTD OTRL CHT CPAM CSCS CKTP. Proximal interphalangeal joint fracture-dislocations are common injuries usually resulting from a direct axial force applied to the tip of the finger. This chapter will focus on describing the indications and the technique for dorsal extension block pinning.

This technique is simple inexpensive and straightforward. Strong has suggested an interesting dynamic PIP joint extension block splint using 2 bent aluminum foam-backed splints secured to the dorsal proximal and middle phalanges. 4 When the digit extends the 2 splints abut one another and block extension of the PIP joint.

In practice we have successfully used this splint but it also has. Extension block splinting if dorsal dislocation that is unstable after reduction. Extension splinting for 6-8 weeks if volar dislocation.

In closed dorsal dislocations reduction is usually prevented by volar plate interposition. Dorsal extension block splint for a joint dislocation 4. Get a tetanus shot and antibiotics if the finger was cut.

If you cut your finger your doctor will likely recommend a tetanus shot to protect you against tetanus. - after reduction keep joint in at least 10-30 deg of flexion w extension block casting. - w unstable dislocations place joint in considerable flexion about 75 deg.

• if x-rays show joint well reduced and congruent apply dorsal block splint. A retrograde K-wire is placed into the head of the proximal phalanx mechanically blocking full extension of the joint and thereby preventing dorsal subluxation of the middle phalanx. The advantages of this technique include its simplicity and the early mobility it affords an injured joint.

As long as the reduction is stable the joint congruent and the fragment if present is small and minimally displaced a dorsal extension block splint is used. Large displaced fragments lead to. Extension block splinting of the proximal interphalangeal PIP joint is a simple and useful treatment option although the practical application of this technique has remained undefined in the literature.

This article provides a step-by-step technique for the construction of a reliable PIP extension block splint and also. Even so one constant in all rehabilitation protocols has remained the Dorsal Blocking Orthosis. A versatile splint that limits the amount of active and passive finger extension to prevent possible tendon rupture.

Among the various regimens though the exact wrist and finger joint placement may differ.
