Significant history/Physical symptoms
First metarsophalangeal (MTP) Joint Dysfunction can be characterised by pain around the joint and associated structures, deformity of the joint position, or by reduced range of movement at the first MTP joint, which can be either structural or functional
Functional Hallux Limitus (FnHL)
Jacks Test (or the Hubscher maneuver) is a clinical test used to estimate the integrity of the windlass mechanism of the foot.

Hallux Limitus / Hallux Rigidus
A dorsal exostosis is characteristic and is caused by proliferation of disease and flexion of the first MTP Joint. Dorsal flexion becomes limited and painful with/without crepitus. Pain can result from an isolated traumatic event but is more frequently associated with repetitive micro trauma or idiopathic arthritis. Increased activities/occupational demands that require extension of the first MTP Joint can be a contributing factor.
- Painful 1st MTP joint
- 1st MTP joint stiffness
- Pain increases with activity/ aggravated by shoes
- Dorsal exostosis
- Inter Phalangeal Joint (IPJ) Hyperextension
- +/- Abnormal ROM 1st MTP joint.
- Central metatarsalgia
- IPJ plantar callus
Radiographic Findings
- Progressive degenerative changes at 1st MTP joint.
- Loss of joint space
- Dorsal osteophytes
- Subchondrial cyst
- Articular flattening
Sesamoid Disorders
Significant History/Physical symptoms
- +/- History of Trauma
- Acute or Insidious onset
- Isolated problem or associated with other 1st MTP joint pathology
- Associated foot deformity
- +/- Swelling, effusion, dislocation, crepitus, erythema, warmth.
- Pain on 1st MPJ ROM/ propulsion
- Localised pain with weight-bearing
- Pain with maximal dorsiflexion
- Pain/ loss of strength on testing plantarflexion
- Pain on direct palpation of sesamoid
Hallux Abducto Valgus
Significant history/physical symptoms
Hallux abducto valgus (HAV) is the most common deformity of the first metatarsophalangeal (MTP) joint. Although research evidence into the cause of HAV are equivocal, the aetiology appears multifactorial—familial history, female gender, occupational foot stress, and an oval or curved MTP joint articular surface have all been partially correlated.
HAV is common, being found in around 2% of children aged nine to ten and in up to 50% of adults, with around 17% of cases becoming symptomatic.
Common progressive deformity of the forefoot characterised by medial deviation of the first metatarsal plus lateral deviation and rotation of the hallux.
HAV has been linked with long term footwear use but the hypothesis that high heels causes HAV is not supported.
Relationship between excessive foot pronation and hallux valgus is inconclusive.
Can be classified using the Manchester Scale.
- Painful “bunion”
- Progressive deformity
- Aggravated by footwear
- Medial prominence – “bunion”
- Deviation of hallux towards midline of foot
- +/- abnormal Range of motion 1st MTP Joint
- Medial bursitis
- Widening of forefoot
- Neuritic “bunion” pain
- Family history
- 2nd hammer toe
Radiographic findings
Radiographs are not recommended for evaluation of HAV. Radiographs should be restricted to those conditions that are progressing to surgery and should only be carried out as part of any pre-operative assessment
- Medial prominence 1st metatarsal head
- +/- joint space abnormality
- > HA angle/ >intermetatarsal angle
- Lateral displacement of sesamoids
- Rotation of Hallux
