Mann's 1995 narrative review covers the two most common first MTP joint disorders — hallux valgus and hallux rigidus — synthesizing a decade of clinical studies into a procedure-selection algorithm for hallux valgus and a pathomechanics-driven treatment framework for hallux rigidus.
When evaluating a bunion, determine congruence and measure the HV and IM angles before choosing a procedure — the algorithm directly maps these values to specific operations.
In hallux rigidus, the target at cheilectomy is 60–70° of passive dorsiflexion on the table; if you can't get there, you haven't removed enough bone.
