ABSTRACT
BACKGROUND:
Die-punch intra-articular fractures of the distal radius raise surgical challenges. The residual articular step-off must be less than 1mm to prevent the development of radio-carpal osteoarthritis. The objectives of this cadaver study were to evaluate whether cementoplasty was effective in reducing die-punch fractures and to determine whether this technique was feasible as an arthroscopic procedure.HYPOTHESIS:
Cementoplasty performed as an arthroscopic procedure is effective in treating die-punch fractures. MATERIAL ANDMETHODS:
Eleven cadaver forearms collected at a laboratory were studied. In each, a depressed fracture of the lunate fossa of the radial articular surface was created using a Tinius Olsen H25K-S compression test machine. A Kyphon XPander® balloon (Medtronic) was used to lift the depressed area, and calcium-phosphate cement was then injected to stabilise the reduction. Cementoplasty under arthroscopic guidance was performed on an additional forearm.RESULTS:
Computed tomography of the wrists after fracture induction showed a mean depression of 4.66mm (range, 4.01-5.25mm). Arthroscopic cementoplasty proved feasible with the arthroscope inserted through the 3-4 radio-carpal portal. Positioning the balloon under the depressed area ensured satisfactory reduction and allowed the injection of cement.DISCUSSION:
Cementoplasty may be useful for the treatment of die-punch fractures. Additional indications may be other types of distal radius fractures with articular surface depression. LEVEL OF EVIDENCE IV, cadaver study.Palabras clave
