A 25-year-old woman presented to the emergency room with a painful and swollen right forearm. She had just sustained an injury from an accident during which her arm was tightly wound by a rope as she was lowering a net from a fishing boat. Before being released, her arm was rigidly trapped in the rope for approximately ten minutes. Radiographs revealed anterior dislocation of the radial head that was accompanied by plastic deformation of the proximal ulna, manifested as a reversal of the proximal dorsal angulation of the ulna (PUDA); suggested a Monteggia equivalent fracture. With the patient under general anesthesia, we reduced the radial head by posterior compression at 90° of elbow flexion and at neutral rotation of the forearm. However, the reduction was easily lost and the elbow re-dislocated with even slight supination or extension of the arm. After the osteotomy of the ulnar deformity to restore the PUDA to normal, the reduction remained stable even with manipulation of the arm. We found that the patient could exercise a full range of motion without pain at the 3-month follow-up, and neither residual instability nor degenerative changes were observed at the final 3-year follow-up.

BACKGROUND: Various deformities can occur in the forearm bones when the traumatically dislocated radial head is untreated for a long period. Without correction of all deformities, reduction of the dislocated radial head is difficult to maintain, and forearm and elbow motion will deteriorate after reduction. We evaluated radiographic parameters of forearms with traumatically dislocated radial heads (and of the normal sides) to understand the resulting deformities and the effectiveness of surgical treatment. METHODS: We analyzed pre- and postoperative anteroposterior and lateral radiographs of 22 forearms (22 patients) with traumatic radial head dislocation. We divided the forearm into three equal parts and measured various morphological parameters. All patients underwent surgical treatment and evaluation of radial head reduction and range of motion pre- and postoperatively. RESULTS: Before treatment, the middle of the ulna was significantly different from the unaffected side in both anteroposterior and lateral views. After surgery, the proximal ulna was significantly different from the unaffected side and the abnormal proximal radial neck angle persisted. The radial head was successfully reduced in 20 of 22 cases. Overall, the mean range of motion decreased after surgery, except for increased flexion-extension. CONCLUSIONS: Complicated deformities developing during long-term remodeling after injury indicate that stable reduction is difficult to achieve with conventional one-bone osteotomy. Even after successful reduction, secondary deformity in the proximal ulna and/or remaining deformity in the proximal radius can hinder forearm rotation.

BACKGROUND: Random type small V-Y advancement flap is widely used for facial reconstruction with advantages including good color and texture match. However, the flap is not as widely used in the extremities and back as in the face because of apprehension of the relatively poor vascularity as a risk factor of flap necrosis. We used a small bilateral V-Y advancement flap for the repair of extremity and back defects from various causes. Competent clinical outcomes are described. METHODS: Between 2007 and 2014, 24 patients (48 flaps) with skin defects in the upper or lower extremities and back were enrolled. The site of the defect was on back (n=6), forearm (n=7), upper arm (n=2), lower leg (n=5), thigh (n=3), and axilla (n=1). RESULTS: Among the 48 flaps, 47 survived (no event: 42 flaps, total necrosis: 1 flap, partial necrosis: 5 flaps). All partial necrotized flaps healed in 3–4 weeks with conservative care. However, debridement and skin grafting was required for the total necrosis flap. One total necrosis and two partial necroses occurred on the anterolateral side of the lower leg. Two partial necroses occurred on the paraspinal area. CONCLUSIONS: Contour deformities including central depression and the dog-ear deformity were not observed. Small bilateral V-Y advancement in the extremity and back could be a safe and useful flap, if thick subcutaneous fat and subcutaneous plexus were saved. But areas with thin subcutaneous fat layer, such as the anterolateral lower leg, are poor candidates and carry the increased risk of improper subcutaneous pedicle circulation.

The authors had five cases of penoplasty from more than half of the scrotum to the suprapubic region using a fasciocutaneous radial forearm free flap (RFFF) after extensive excision of sclerosing lipogranuloma. Although the harvested RFFF was a rectangular shape, the authors made the shape of scrotum, penile shaft, and suprapubic region by using well designed geometry and several quilting sutures on junction of scrotum and penis. The contour of scrotum and penis was well maintained, and there were no complications, such as scrotal contracture, penile deformity, and erectile dysfunction during the one year follow up period in all five cases. There were no recurrent lesions and no need for further surgery.

During imaging studies or surgical procedures, anomalous forearm and wrist muscles are occasionally encountered. Among them, the flexor carpi radialis brevis is very rare. Because the trend is growing toward treating distal radius fractures with volar plating, the flexor carpi radialis brevis is worth knowing. Here, we report two cases with a review of the literature.

Anatomical variations are typically more common in the extensor compartment of the forearm, but uncommon in the flexor compartment. The presence of such anatomical anomalies is not usually noticed until the normal functions of an individual become hindered, or when these anomalies become a surgical problem. During routine dissection curriculum, we encountered a rare finding of bilateral Gantzer muscles in a cadaver. We describe the relationship between the Gantzer muscle and anterior interosseous nerve syndrome.

Congenital radial dysplasia is a rare disease with the defect or hypoplasia of radial side of forearm and hand. Congenital radial dysplasia is often accompanied by deformities of other parts. However, carpal tunnel syndrome caused by congenital radial dysplasia is very rare. We report one case of 53-year-old man with congenital radial dysplasia who underwent surgery for carpal tunnel syndrome.

Congenital syngnathia refers to the fusion of bony tissues, a rare disorder with only 41 cases reported in the international literature from 1936 to 2009. The occurrence of syngnathia without any other associated systemic disease or congenital anomaly is extremely rare. This report presents a case of congenital syngnathia with unilateral maxillomandibular bony adhesion without any other oral or maxillofacial anomaly. No recommended protocol for surgery exists due to the rarity of the disorder. There is a very low survival rate for the few patients who have forgone surgical management. This case describes a 74-year-old female patient who was suffering from limitation of mouth opening and was subsequently diagnosed with congenital syngnathia. The surgical staff performed separation surgery and reconstructed the malformed oral vestibule and cheek using the radial forearm free flap operation.

Radial longitudinal deficiency, also known as radial club hand, is a congenital deformity of the upper extremity which can present with a spectrum of upper limb deficiencies. The typical hand and forearm deformity in such cases consists of significant forearm shortening, radial deviation of the wrist and hypoplasia or absence of a thumb. Treatment goals focus on the creation of stable centralized and functionally hand, maintenance of a mobile and stable wrist and preservation of longitudinal forearm growth. Historically centralization procedures have been the most common treatment method for this condition; unfortunately centralization procedures are associated with a high recurrence rate and have the potential for injury to the distal ulnar physis resulting in a further decrease in forearm growth. Here we advocate for the use of a vascularized second metatarsophalangeal joint transfer for stabilization of the carpus and prevention of recurrent radial deformity and subluxation of the wrist. This technique was originally described by the senior author in 1992 and he has subsequently been performed in 24 cases with an average of 11-year follow-up. In this paper we present an overview of the technique and review the expected outcomes for this method of treatment of radial longitudinal deficiency.
