How Should a Clinical Thermal Image Be Recorded and Evaluated?
Published in Kurt Ammer, Francis Ring, The Thermal Human Body, 2019
When the fingers are spread, the basic phalanx of the index finger and the second metacarpal bone form an open angel on the radial side, while the basic phalanx of the little finger and the fifth metacarpal bone form an open angel on the ulnar side. Connect the apex of these angles with a line.

Attachments of opponens digiti minimi– origin: hook of hamate– insertion: medial surface of fifth metacarpal bone– nerve SS: deep branch of ulnar n. (C8, T1)– function: lat. rotate fifth metacarpal bone

After arising from the humerus, the extensor carpi radialis longus and extensor carpi radialis brevis pass distally, crossing the wrist, and insert upon the second and third metacarpal bones, respectively. The extensor carpi ulnaris inserts upon the fifth metacarpal bone. These three muscles are important extensors of the wrist. Just proximal to the wrist the tendons of the two radial extensors are crossed, first by the abductor pollicis longus, then the extensor pollicis brevis.
Closed extensor tendon rupture following neck fracture of the fifth metacarpal (Boxer’s fracture): a case report

The initial standard AP and oblique X-rays of the hand showed a comminuted neck fracture of the fifth metacarpal bone (Figure 2) with slight apex dorsal angulation. Subsequent dynamic ultrasound examination showed local hematoma with suggestion of a total rupture of the fifth extensor digitorum communis (EDC) and the extensor digiti minimi (EDM) tendons just proximal to the MCP joint, known as zone V (Figure 3). A splint was applied at the ED and 3 days later the patient was admitted to the operating theater for exploration and primary tendon repair. Complete rupture of both the EDC and the EDM was confirmed (Figure 4). Tendon repair suturing was performed using a 4-strand core suture technique. The fracture was treated conservatively. A volar splint in intrinsic plus position was applied for 2 weeks. After 2 weeks the plaster was removed and the patient was referred to hand therapy. Three months after surgery, the patient showed excellent functional outcome with full range of active flection and extension of the MCP, PIP and DIP joint (Figure 5) and normal grip strength. The patient has returned to work and sports. There were no complications.

The surgery was carried out under axillary block and by tourniquet hemostasis. The mass was dorsally approached through a curved skin incision over the IV inter-metacarpal space (Figure 2(A)). The mass laid in the subfascial space, and after careful dissection from the dorsal interosseous muscles that were displaced by the tumor had been dissected from the volar compartment. The inter-metacarpal ligament between the fourth and the fifth metacarpal bones was left intact as there was enough space for the mass to be pulled dorsally and dissected (Figures 2(B,C)). No intramuscular infiltration was evident. Marginal excision of the lesion was performed and the encapsulated elliptical mass (70 mm length, 35 mm width) was removed en bloc from both the volar and dorsal compartments. It appeared as a lobular fatty mass (Figure 2(D)). Immediately after surgery, the hand was protected with a volar splint that left the metacarpal–phalangeal joint free to move. Ice was applied over the wound to prevent swelling and edema.
A patient with macrodystrophia lipomatosa bilaterally affecting the entire upper extremity: reporting of a rare case and literature review

The bilateral overgrowth of the upper extremities occurred, extending from the shoulders to the fingers (Figures 1 and 2). Both the length and circumference of the upper extremities increased. The overgrowth of the ring and little fingers, as well as of the palm corresponding to the fourth and fifth metacarpal bones was not obvious in the left hand. Any congenital anomalies (e.g. syndactyly) were not found, except the bilateral, disproportional overgrowth of the upper extremities. Surgical cicatrices were found in the extensor aspect of the radius of both upper extremities, in an area between the flexor aspect of the right wrist joint and the palm of the right hand, and in the first interdigit of the left hand.
