矫形

Mostly attributive: 矫形外科 (orthopedic surgery), 矫形手术 (corrective surgery), 矫形器 (orthotic device), 矫形鞋 (orthopedic shoes). Note that the broader term for "orthopedics" as a hospital department is 骨科 (gǔkē, "bone department") — 矫形 specifically emphasizes correcting deformities (bone, skeletal alignment, dental orthodontics).

memory

矫 (jiǎo, "to straighten / correct") + 形 (xíng, "shape") = "to correct shape." The 矫 component appears in 矫正 (correct), 矫枉过正 (overcorrect), 矫健 (vigorous, sturdy).
