The patient already had anesthetic placed by way of metacarpal block via lidocaine with epinephrine. We use the Jahss Maneuver to reduce the fracture....more

The Jahss maneuver is perhaps the most effective method for closed reduction of finger metacarpal neck fractures. This is demonstrated and explained in less ...

Displacement usually occurs as a flexion deformity that can be reduced by exerting pressure on the metacarpal head from the palmar aspect, either directly or using the proximal phalanx as a piston (Jahss maneuver). Check for correct alignment with an image intensifier.

The Jahss manoeuvre is described for reduction of volar displaced metacarpal neck fractures with good results. 1 It is performed by flexion of the metacarpophalangeal and proximal interphalangeal joint to 90° and the proximal phalanx is used to push the metacarpal head up to achieve reduction. 1 In proximal phalangeal volar displaced neck ...

Jan 28, 2017 · The most commonly used reduction technique is the Jahss maneuver. The MP and interphalangeal (IP) joints are flexed 90 degrees to relax the intrinsic muscles and tighten the collateral ligaments.

Sep 4, 2018 · After appropriate anesthesia, a closed manipulation of the metacarpal neck fracture is performed by the Jahss maneuver (see Figure 7.2 ). This maneuver is accomplished by flexing the MP and PIP joints to 90 degrees and exerting upward pressure through the flexed proximal phalanx and simultaneous downward pressure on the metacarpal shaft.

May 21, 2020 · The Jahss maneuver, as previously described, is performed for reduction before the K-wires are passed into the medullary canal. The bouquet osteosynthesis has the advantage of maintaining reduction without opening the fracture site and interfering with the …

Jan 6, 2024 · The Jahss maneuver for reduction of volar displaced metacarpal neck fractures involves flexion of the metacarpophalangeal and proximal interphalangeal joint at 90°, with the proximal phalanx used to reduce the metacarpal head.

Jahss reduction technique. This technique, also known as the 90-90 approach, involves flexing the patient's MCP and PIP 90 degrees. Dorsal force is applied to metacarpal head by through dorsal pressure on the proximal phalanx.
