Lachman's test of the foot is a special examination technique used to evaluate for metatarsophalangeal joint instability as seen in Freiberg's disease

This video illustrates both the functional anatomy of the plantar plate during Metatarsal Phalangeal Joint Dorsiflexion while intact, as well as when a full rupture has occurred. This positive...

2024年7月31日 · A short video of an unstable 2nd toe, assessed clinically by the Lachman's Test (dorsal plantar drawer test). DISCLAIMER. Videos on this channel contain surgical or injection therapy procedures that may be graphic in nature.

A positive anterior-posterior draw test (Modified Lachman Test). The clinician stabilises the patient's toe at the metatarsal and exerts a drawer test on the phalanges. A slight clunk can be heard as the joint subluxes in the plantar direction. It is considered the most reliable and accurate tool to classify and grade a plantar plate lesion.

2022年10月24日 · The Vertical Lachman test tests the degree of vertical translation of the proximal phalanx compared to the metatarsal; it is important to compare this to the contralateral side. A positive test shows more laxity than the contralateral side.

The 1st MTP drawer test, sometimes called the lachman's test of the toe, is used to evaluate for the integrity of the plantar plate or for turf toe.

The Lachman test for the first MTPJ is conducted by stabilizing the first metatarsal superiorly and inferiorly with 1 hand while applying an anterior and posterior translational force to the proximal phalanx to feel for dorsal or plantar subluxation. A positive Lachman test demonstrates anteroposterior instability. Table 3.

Instability of the joint is demonstrated with increased mobility of the second MTP joint. A crossover second toe is a commonly seen forefoot problem, usually occurring in women aged > 50 years,...

2017年11月20日 · Digital Lachmans / Vertical Stress Test (Fig 5) Same style of test to assess ACL tears, helps to assess the integrity of the plantar plate, it is quick, easy and a simple test to perform.

The test is claimed to be most useful when the Lachman test is stage 0 (no laxity to dorsal translation). The test is described as: patient seated; foot hanging free over edge of surface; midfoot is grasped with one hand and the other hand grasps the affected toe; the index finger should be placed over the dorsum at the base of the proximal phalanx
