case_images: The patient's elbow extended -60  (a) and flexed 95  (b) before the operation.

case_images: fig1-2050313X231216597
case_images: Passive elbow extension was as great as -60 ; flexion was 95  with no instability (Figure 1(a) and (b)).
case_images: Radiographs of the left elbow showed narrowing joint space and bone hyperplasia before the operation: (a) anteroposterior view; (b) lateral view. (c) Computed tomography (CT) coronal view showed some loose bodies in the olecranon fossa (arrowhead) and subchondral bone irregularities of the trochlea of humerus (arrow). (d) CT axial view showed sclerosis with occlusion of the ulnar medullary cavity (arrowhead) and a few hypertrophic loose bodies around radial head (arrow) at the proximal radioulnar joint. (e) CT coronal view showed sclerosis with occlusion of the humerus medullary cavity at the proximal supracondylar humerus (arrowhead).

case_images: fig2-2050313X231216597
case_images: Radiographs of the left elbow showed narrowing joint space and bone hyperplasia (Figure 2(a) and (b)). Computed tomography (CT) showed some loose bodies in the olecranon fossa, subchondral bone irregularities of the trochlea of humerus (Figure 2(c)), and sclerosis with occlusion of the humerus and medullary cavity and a few hypertrophic loose bodies around the radial head (Figure 2(d) and (e)).
case_images: (a) Cartilage defect and eburnation were found in the joint surface of the head of the radius. (b) Extracted joint free body. (c) Cartilage defects were found in the articular surface of the capitellum of the humerus (arrow) and ulnar trochlear notch (arrowhead).

case_images: fig3-2050313X231216597
case_images: Cartilage defect and eburnation in the joint surface of the head of the radius were found and subsequently excised (Figure 3(a)). The joint loose body (3 cm long axis, 1.5 cm short axis) in the front of the head of the radius was removed (Figure 3(b)). The articular surface of the capitellum of the humerus and the ulnar trochlear notch showed a cartilage defect (Figure 3(c)).
case_images: (a) Postoperative X-ray showed a fracture line on the medial part of the supracondylar humerus (arrow). (b) Swollen upper left extremity with blisters caused by skin circulation difficulties.

case_images: fig4-2050313X231216597
case_images: Postoperative X-ray showed a fracture line on the medial part of the supracondylar humerus (Figure 4(a)). His upper left limb was swollen and blistered because of cutaneous circulatory disturbance (Figure 4(b)).
case_images: Radiographs at 30-month follow-up: (a) anteroposterior view; (b) lateral view. Before correction: The patient's elbow flexed 140  (c) and extended -30  (d) and pronated 80  (e) and supinated 90  (f) at the 30-month follow-up.

case_images: fig5-2050313X231216597
case_images: At the 30-month follow-up visit, the patient was found to have no neurovascular deficit or implant difficulty visible by X-ray (Figure 5(a) and (b)). He was able to achieve extension to -30  (Figure 5(c)), flexion to 140  (Figure 5(d)), supination to 90  (Figure 5(e)), and pronation to 80  (Figure 5(f)).
