Clinical characteristics and results after conservative treatment or interfascicular neurolysis of 100 limbs with spontaneous anterior interosseous nerve palsy: A prospective Japanese multicenter study.

Background: Spontaneous anterior interosseous nerve (AIN) palsy is characterized by the sudden onset of upper limb pain followed by weakness of muscles mainly innervated by the AIN. Although this palsy is conventionally treated conservatively, interfascicular neurolysis to release hourglass-like fascicular constrictions has been recommended. The present study aimed to establish the clinical characteristics and treatment strategy for this condition.

Use of Distal Hypothenar Perforator Free Flaps for Pulp Defects.

A hypothenar perforator free flap, which is harvested from the palm, is suitable for reconstruction of a finger pulp skin defect, but this flap has rarely been reported, and most of these flaps in previous published reports were designed on the proximal zone of the hypothenar area. In the present report, hypothenar perforator free flaps on the distal zone, namely distal hypothenar perforator free flaps, including two sensate flaps, were used for four cases with pulp defects. Four distal hypothenar perforator free flaps were used for four patients with skin defects of the finger pulp, including one thumb, two index fingers, and one little finger.

Free Thoracoacromial Artery Perforator Flap for Skin Defects of the Dorsal Hand.

Various flaps are used for skin defects of the dorsal hand and fingers. A sensory flap is not essential, but a thin and good color-matched flap is suitable, and donor site mobility of the flap should be considered. A reverse or free posterior interosseous artery perforator flap is one of the standard flaps.

Suspension Arthroplasty for Old Fracture-Dislocations of the Fifth Carpometacarpal Joint.

It is well known that treatment of the old fracture-dislocations of the fifth carpometacarpal (CMC) joint is challenging. For patients with persistent pain due to this condition, numerous surgical techniques have been proposed. Here, we present a novel surgical technique, CMC joint suspension arthroplasty, using a partial slip of the extensor carpi ulnaris tendon.

Surgical Management of Unilateral Soft Tissue Swelling around the Proximal Interphalangeal Joint in an Adolescent: A Case Report of Pachydermodactyly.

Pachydermodactyly (PDD) is a rare and benign acquired form of digital fibromatosis, characterized by asymptomatic fusiform soft tissue hypertrophy of the lateral aspect of the proximal interphalangeal (PIP) joints of the fingers. The etiology of PDD remains unknown, but it usually affects healthy males around the age of puberty. It can be misdiagnosed as inflammatory rheumatic diseases, especially as juvenile chronic arthritis.

Primary On-top Plasty for Treatment of Short-type Postaxial Polydactyly of the Foot.

Background: Postaxial polydactyly of the foot is typically treated with medial or lateral toe ray resection. However, simple ray resection does not always give a natural postoperative appearance, especially for short-type polydactyly. The purpose of this article was to describe our primary operation with on-top plasty for lengthening of short-type postaxial polydactyly.

Use of free ipsilateral gastrocnemius flap for coverage of distal third tibial defect after Gustilo type III open fracture.

The traditional pedicled gastrocnemius muscle flap has often been used to repair soft-tissue defects caused by trauma. However, it is difficult to cover skin defects in the distal third of the lower extremity because of its range of excursion. We have attempted use of a free ipsilateral gastrocnemius muscle flap for coverage of skin defects in the distal third of the lower extremity.

Indication and practice of reverse flow extensor digitorum brevis muscle flap transfer.

Although the pedicled extensor digitorum brevis (EDB) muscle flap is a versatile flap, there are not many reports about it. Furthermore, there are few reports about the reverse vascular flow EDB muscle flap. The lateral tarsal artery coming from the dorsalis pedis artery nourishes the EDB muscle flap.
