3D Printing Models in Surgical Planning of Osteotomies in Kienbock´s Disease Stages II-III

3D Printing Models and Personalized Guides in Surgical Planning of Shortening, Wedge and Dorsolateral Biplane Closing Osteotomies in Kienbock´s Disease Stages II and III.

Ischemic necrosis of lunate bone, osteonecrosis or Kienböck´s disease was described by Kienböck in 1910. Numerous surgical procedures for this disease had been proposed. These surgical options, that depends of the radiological stage and anatomical risk factors, can be classified into lunate unloading procedures, lunate revascularization, replacement procedures and salvage procedures. These procedures, except the salvage procedures, has been successful in reconstructing and maintaining the height of the carpus, avoiding progression of the disease and with reduction of the pain.

The lunate unloading procedures are surgical treatments that make a radial osteotomy for modify differents anatomical risk factors associated with the osteonecrosis.

Detailed Description

The anatomical factors associated with Kienböck´s disease are morphology of the lunate type I by Antuña-Zapico, cubitus minus, radial inclination angle greater than 23º, and little coverage of the lunate by the radius.

The types of radial osteotomy for Kienböck´s disease stages II, IIIA, IIIB or IIIC, depends to the anatomy of the patient and its anatomical risk factors. For patients with cubitus minus the indication is usually a radial shortening osteotomy. For patients with zero variant and an increase in the radial inclination angle the indication is usually a closed wedge radial osteotomy. The dorsolateral biplane radial osteotomy is used for zero variant cases such as a modification of the technique proposed by Nakamura et and Miura et al. It decompresses the lunate on the frontal plane and reduces dorsal radiolunate impingement on hyperextension. Dorsolateral radial osteotomy ensures a reduction of the radial inclination angle and a corresponding lunate decompression on the anteroposterior and sagittal plane.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Clinical evaluation preoperative and postoperative: Mayo Wrist Score
Time Frame: 22 months
Modified Mayo Wrist Score (MWS). It is based on pain, range of motion, grip strength and function. Scores of 80 to 100 are considered excellent; 65 to 79, good; 50 to 64, moderate; and less than 50, poor.
22 months
Disabilities of the arm, shoulder and hand score questionnaire
Time Frame: 22 months
Disabilities of the arm, shoulder and hand score (Quick DASH) questionnaire. From 0 (better outcome) to 100% (worse outcome)
22 months
Clinical evaluation preoperative and postoperative: Grip strength
Time Frame: 22 months
Grip strength mesure with a Jamar dynamometer (in Kilograms).
22 months
Radiological variables In the posteroanterior radiographs wrist: Lichtman classification
Time Frame: 22 months
Lichtman´s Stage of lunate necrosis classification: 4 stages (1977). Better stage 1, worse stage 4.
22 months
Radiological variables In the posteroanterior radiographs wrist: Carpal Ulnar Distance Ratio.
Time Frame: 22 months
Carpal Ulnar Distance Ratio (mesure in millimeters) by McMurtry-Youm (1978). Outcomes in a ratio 0.30+-0.03.
22 months
Radiological variables In the posteroanterior radiographs wrist. Carpal Height Ratio.
Time Frame: 22 months
Carpal Height Ratio (measure in millimeters) by McMurtry-Youm (1978) . Outcomes in a ratio 0.54+-0.03.
22 months
Radiological variables In the posteroanterior radiographs wrist: Radial Inclination Angle.
Time Frame: 22 months
The Radial Inclination Angle (RIA) describes the angulation of the distal radial articular surface in relationship with the long axis of the radius or ulna as seen in the posteroanterior view of the wrist. We measure RIA in relationship with the long axis of the ulna. The normal limits are 18.8° to 29.3° (measure in degrees).
22 months
Radiological variables In the posteroanterior radiographs wrist: Lunate covering Ratio.
Time Frame: 22 months
The Lunate Covering Ratio (LCR) is a measure of the lunate surface protected by the radius, obtained by dividing the width of lunate covered by radius by total lunate width in millimeters x 100.
22 months
Radiological variables In the posteroanterior radiographs wrist. Ulnar Variance.
Time Frame: 22 months
Ulnar variance was measured as described by Gelberman et al. (1980) The measurement was obtained by projecting a line from the carpal joint surface of the distal end of the radius toward the ulna and measuring the distance in millimeters between this line and the carpal surface of the ulna. Ulnar shortening values of 2 or more millimeters are described as negative ulna or cubitus minus. Zero variant or neutral ulna with ulnar variance or distal radio-ulnar index is between 0-2 mm and cubitus plus when ulnar elongation values greater than 2 mm.
22 months
Clinical evaluation preoperative and postoperative: Pain
Time Frame: 22 months
Visual Analog Score, from 0 to 10. Better outcome 0 and worse 10.
22 months
Clinical evaluation preoperative and postoperative: Range of motion
Time Frame: 22 months
Range of motion (ROM): wrist motion (flexion, extension, radial deviation, ulnar deviation, pronation, supination) mesure with a goniometer (in degrees).
22 months

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Radiological variables in the lateral radiograph in the wrist: Palmar Tilt
Time Frame: 22 months
Palmar tilt (PT) measure in degrees. Palmar tilt is determined by the line drawn across the most distal points of the dorsal and ventral rims of the distal articular surface. The degree of PT is derived by the intersection of the line of PT and a line perpendicular to the long axis of the radius, as seen in the lateral view. The normal limits are 0° to 18°.
22 months
Radiological variables in the lateral radiograph in the wrist: Stahl´s Index
Time Frame: 22 months
Stahl´s index measures the degree of lunate fragmentation and collapse. The normal limits are 0.53+- 0.03. The longitudinal height of the lunate measured on the lateral view is divided by its greatest dorsopalmar dimension. The ratio of these 2 measurements gives the Stahl index.
