STAGE DORSIFLEXION ROM RADIOGRAPHIC FINDINGS CLINICAL FINDINGS TREATMENT PLAN TREATMENT GOALS Stage–0 40°-60° Normal No pain, with minimal stiffness & loss of motion on NWB examina- tion NP foot orthosis with first-ray cutout. Standard footwear Return individual to full motion, & prevent progres- sion Stage–1 30°-40° Dorsal osteophyte with minimal joint space narrowing Occasional/mild pain and stiffness; pain at extremes of dorsiflexion on NWB examination Orthoses with first-ray cutout; a wider higher toe box to reduce osteophyte fric- tion and a com- mercial rocker- soled shoe Same as Grade 0, but also trying to prevent pain due to dorsal osteo- phyte Stage–2 10°-30° Dorsal, medial, and lateral osteo- phytes giving metatarsal head a flattened appear- ance; mild-to- moderate joint space narrowing & sclerosis Moderate-to- severe pain and stiffness; pain occurs just before maximal dorsi- flexion & plan- tarflexion on NWB examination Orthoses with an extended medial shell and/or a rigid rocker-soled shoe. This may require the addi- tion of a rigid shank Limit motion in order to reduce pain Stage–3 < 10° Same as Grade 2, but with signifi- cant joint space narrowing & scle- rosis; sesamoids are enlarged, cys- tic, or irregular Constant pain and stiffness at end range of motion, but not at mid-range Rigid, rocker- soled shoe with the apex just proximal to the MTPJ’s. May require a rigid shank and a thicker sole to accommodate the rocker angle needed for a smooth gait Allow for smooth gait, while com- pletely immobiliz- ing the 1st MTPJ to reduce pain Stage–4 Same as Grade 3 Same as Grade 3 Same as Grade 3, but pain present also at mid-range of motion Same as Grade 3 with the addi- tion of a MAFO if restriction of forward motion of the tibia is desired Completely immobilize the 1st MTPJ while the joint auto-fuses, or is surgically fused/ replaced Table 1: Classification of Hallux limitus/rigidus with conservative treatment plan and goals.
