hallux limitus

Limitation of range of motion of the first metatarsophalangeal joint, usually with arthritic degeneration of the joint and pain. See: hallux rigidus
See also: hallux

hallux limitus

first-ray pathology characterized by restricted dorsiflexion (reduced sagittal-plane motion; i.e. <60° available dorsiflexion) at first metatarsophalangeal joint, during the propulsive phase of gait (Table 1 and Table 2 and Box 1, Figure 1; see synovitis)
  • acute hallux limitus acute-onset first metatarsophalangeal joint inflammation due to stubbing the great toe; see toe, turf

  • functional hallux limitus reduced range of dorsiflexion motion at the first metatarsophalangeal joint (see functional hallux limitus)

Table 2: Classification of stage of hallux limitus/rigidus
Stage 1
Functional HL
∼60° available dorsiflexion at 1 MTPJ
Functional (weight-bearing) limitation of dorsiflexion at 1 MTPJ, with:
• 1 MTPJ painful under load
• Hypermobility of first ray
• No real joint deterioration, but some osteophytosis
• Non-weight-bearing 1 MTPJ dorsiflexion near normal
Stage 2
Mild structural HL
35-55° available dorsiflexion at 1 MTPJ
Structural limitation of dorsiflexion at 1 MTPJ
• 1 MTPJ painful after exercise/movement
• Broadening and flattening of 1 MTPJ surfaces
• Narrowing of 1 MTPJ space
• Moderate osteophytosis of 1 MTPJ area
• Local bone sclerosis
• Elevation of the first ray
• Sesamoid hypertrophy
• Reduced 1 MTPJ dorsiflexion (weight- and non-weight-bearing)
• Reduced heel lift
• 1 MTPJ crepitus
Stage 3
Moderate structural HL
15-30° available dorsiflexion at 1 MTPJ
Structural loss of dorsiflexion at 1 MTPJ
• Pain within 1 MTPJ
• Marked 1 MTPJ deterioration
• Loss of 1 MTPJ space
• Extensive osteophytosis
• Bone sclerosis
• Cystic degeneration of subchondral bone
• Joint 'mice'
• Hypertrophy of sesamoids
• Elevation of the first ray
• Loss of height of MLA
• Decreased calcaneal angle
• 1 MTPJ crepitus
• Marked reduction of heel lift
Stage 4
Severe HR
<15° available dorsiflexion at 1 MTPJ
1 MTPJ immobility
• 1 MTPJ ankylosis and loss of joint space
• Marked osteophytosis and increased bulk of 1 MTPJ
• Loss of heel lift and/or hyperextension of IPJ of hallux

1 MTPJ, first metatarsophalangeal joint; MLA, medial longitudinal arch; IPJ, interphalangeal joint.

Box 1: Gait and postural effects of hallux limitus/rigidus
  • Loss of heel leverage due to reduced dorsiflexion at the first MTPJ affects transfer of weight from rearfoot to forefoot

  • Obligatory pronation of the foot about the oblique axis of the MTJ and abduction of the forefoot occur in order to achieve a degree of toe off

  • Obligatory lower limb pronation including:

    • Internal rotation of tibia

    • Internal rotation, increased transverse-plane motion and medial knee strain

    • Internal rotation of the lower limb at the hip and lateral hip pain

  • Increased lumbar lordosis, forward tilt of the pelvis and lower-back pain

  • Thoracic kyphosis, forward tilt of the cervical spine with compensatory 'hunched' back/'bad' posture/'round' shoulders

  • Hyperflexion of the cervical spine, neck tension and tension headache

  • Gait effects include:

  • Foot pronation throughout ground contact and at toe off

  • Short stride length

  • Early knee flexion

  • Reduced heel lift

  • Decreased thigh extension

  • Diminished arm swing (to match reduced stride length)

  • Apropulsive gait

En referencia a la funcion y consecuencias biomecanicas del Mecanismo de Windlass respecto al Hallux Limitus, existen multitud de estudios en dinamica que muestran la relacion del Hallux Limitus sobre la posicion del pie en la marcha, uno de ellos es el de Harradine y Bevan, (4) en el cual confirman que a mayor eversion del retropie menor flexion dorsal de la primera articulacion metatarsofalangica, mostrando asi que existe una relacion entre el Hallux Limitus Funcional y la pronacion, pero en este estudio, solo lo valora a nivel del retropie.
Pero en cambio, en estatica no hay muchos articulos, de ahi la importancia de estos tipos de estudio, como el estudio de Paton (15) que demuestra que, existe una relacion entre la disminucion de la flexion dorsal del hallux en estatica, Hallux Limitus Estructural y la pronacion a nivel de la articulacion mediotarsiana con la prueba del Navicular Drop en estatica.
Una vez revisados todos los estudios consultados, se observa la asociacion existente entre el hallux limitus y la hiperpronacion, como principal factor etiologico.
La mayoria de los estudios revisados, se realizan en dinamica comparando el hallux limitus con pruebas como el navicular drop, el valgo de retropie o con ortesis plantares con cunas en valgo o invertidas, mostrando una relacion de la deformidad con un exceso de pronacion en dinamica, pero tambien se evidencia la falta de estudios que muestren la relacion con la estatica o posicion del pie, para si poder tener una relacion causa efecto mas alta, dejando asi la puerta abierta a posibles nuevos estudios sobre el tema.
