Lateral Elbow

The anconeus muscle is a small and minor functioning muscle located at the posterolateral elbow region. It helps forearm extension and tightening of the joint capsule. Despite its limited functions, pathologies of the anconeus muscle can mimic other abnormalities of the elbow joint. Here, we report a rare case of a traumatic anconeus muscle contusion in a 15-year-old boy due to falling during dance. MRI showed contusion in the anconeus muscle, as well as strain in the ulnar collateral ligament and edema in the coronoid process of the ulna. To our knowledge, this is the first described case of traumatic anconeus muscle contusion in the literature. The presence of long-lasting lateral elbow pain in trauma cases without fracture should alert clinicians to consider anconeus muscle abnormalities. MRI is the best modality for diagnosis in these cases.

Little Finger

We managed a case of locked metacarpophalangeal joint of the little finger in the extension position. Incarceration of a chronic osteochondral fracture fragment led to this unique condition. The fracture fragment partially adhered to the volar plate and ulnar collateral ligament on the joint side, which is supposed to have resulted in manually irreducible locking of the joint. We performed open reduction and achieved release of the locked joint by excising the fracture fragment.

The Stability

Background: Thumb ulnar collateral ligament (UCL) injuries are common, but the kinematics of these injuries have not been comprehensively described, especially regarding kinematic changes with progressive UCL injury. Methods: Eleven cadaveric thumbs underwent kinematic testing under 4 conditions: intact, partial tear (50%) of the proper UCL, full tear of the proper UCL, and complete tear of both the proper and accessory UCL. Kinematic testing parameters included varus/valgus stress, pronation/supination, and volar/dorsal translation at −10 degree, 0 degree, 15 degree, and 30 degree of metacarpophalangeal flexion. Results: Partial tear of the proper UCL did not result in significant increases in laxity in any direction compared with intact ( P ≥ .132). Full tear of the proper UCL resulted in a significant increase in valgus angulation (18.8° ± 1.7° vs 11.5° ± 1.5°; P = .024) and pronation (15.4° ± 2.5° vs 12.6° ± 2.3°; P = .034) at 30 degree of flexion relative to intact. Complete tear of both the proper and accessory collateral ligaments resulted in increased valgus angulation at all degrees of flexion ( P < .001). Complete tear also resulted in a significant volar translation at 0 degree, 15 degree, and 30 degree of flexion ( P ≤ .016). Conclusion: Partial tear of the proper UCL does not significantly affect the stability of the joint, but full tear of the proper UCL increases valgus instability at 30 degree of flexion. Complete tear of the UCL is necessary for increased varus/valgus instability at all degrees of flexion and results in significant increases in pronation/supination and volar translation.

Tissue Defects

Background: Soft tissue defects about the elbow with concurrent ligamentous instability can be challenging to treat. Methods: We present a case report of a lateral elbow wound that resulted in lateral ulnar collateral ligament deficiency and posterolateral elbow instability. Results: We describe our technique of a modified brachioradialis rotational flap, in which the muscle is rotated to cover the soft tissue defect, while the vascularized brachioradialis tendon is used to simultaneously reconstruct the lateral ulnar collateral ligament. This procedure successfully restored posterolateral elbow stability at the time of wound coverage. Conclusion: Elbow soft tissue defects with associated ligamentous injuries can be treated using a modification of the brachioradialis rotational flap.
