The presence of accessory tendons might assist in finding alternative tendon sources for tendon grafts. A thin accessory tendon was detected from the extensor carpi ulnaris (ECU) at the ulnar styloid process.Ĭonclusion: Tendon variations of the dorsal compartments of the wrist and the relationship between the ED slip and accessory tendons should be considered when planning surgical treatment. The lateral was accepted as the main APL and the medial as the accessory tendon.

Four out of fourteen wrists (28.5%) had APL tendon variations. The radial tendon was accepted as an accessory EDQP but did not join the extensor digitorum (ED), and the ulnar tendon was normal. Ulnar and radial tendons of the EDM were detected in the right wrist of one female cadaver. Results: A double tendon of the extensor digiti minimi was detected in one female cadaver out of the 14 fixed cadavers. The tendon variations in the extensor compartments of the wrist and their abnormal insertion sites were recorded, and the number, length, width, and type of accessory tendons were also recorded. Methods: Fourteen fixed wrists of adult cadavers were dissected.

This study was performed to investigate the variations of the extensor compartments of the wrist and a relation between the thickness of extensor digiti minimi (EDM) and abductor pollicis longus (APL) tendons and accessory extensor digiti quinti proprius (EDQP) slip to the little finger. De Quervains TendosynovitisObjective: Detailed anatomical knowledge of the accessory tendons of the dorsal compartments of the wrist is crucial for understanding the effects of tendon injury due to external trauma or rupture. Movements involving grasping or pinching are particularly painful and difficult.Ĭonservative management of De Quervain’s tenosynovitis involves lifestyle advice (avoiding repetitive actions) and a wrist splint. Steroid injections will reduce swelling and relieve pain in most cases, and can be repeated several times if a good response is observed.įor those failing to respond to conservative management, surgical decompression of the extensor compartment can be performed under local or general anaesthetic. Patients with De Quervain’s tenosynovitis will often complain of pain near the base of the thumb with an associated swelling (secondary to thickening of the tendon sheath). It is most common in women between the ages of 30-50, especially in those with occupations or hobbies involving repetitive movements of the wrist.

De Quervain’s tenosynovitisis inflammation of the tendons within the first extensor compartment of the wrist, resulting in wrist pain and swelling.
