Clavicle medial end fracture is rare, and it has not been studied extensively. Although there is debate regarding its treatment methods, because of the complications of conservative treatment, surgical treatment has been considered more than conservative treatment. This study describes a surgical method using double-plate fixation for treatment of clavicle medial end fractures in which plates were used on each anterior and superior border according to the anatomical structure of the clavicle. In addition, we report operative results of three patients treated by double-plate fixation.

Humeral head chondrolysis has been widely reported as a devastating complication after arthroscopic shoulder surgery; however little is known about post-arthroscopic humeral head osteonecrosis. We experienced a 66-year-old female patient with rapidly progressive osteonecrosis of the humeral head only seven months after arthroscopic Bankart and rotator cuff repair. The patient had no systemic risk factors for osteonecrosis. A satisfactory result was achieved with reverse total shoulder arthroplasty for severe humeral head destruction and an irreparable massive rotator cuff tear. Shoulder surgeons should be aware of such severe complication, perform routine radiographs, and pay close attention to the presence of constant pain or loss of motion after arthroscopic shoulder surgery.

Although the lateral discoid meniscus of the knee has been observed frequently, the medial discoid meniscus has very rarely been reported in the literature. A 22-year-old female patient was diagnosed as having a medial discoid meniscus with horizontal tear by means of magnetic resonance image and arthroscopy. The patient was treated by arthroscopic partial meniscectomy.

Primary osteoarthritis of the ankle without history of trauma is rare. We are reporting the use of a low tibial osteotomy on 2 ankles in one patient. The osteotomy is designed to correct the varus tilt and anterior opening of the distal tibial joint surface where it has been shown by weight-bearing radiographs. Follow-up at 8 months the result showed to be excellent, by Takakura's scoring system. We experienced that slight overcorrection of deformity by low tibial osteotomy is effective in treating intermediate-stage primary osteoarthritis of the ankle.

For the adequate intraarticular exposure in medial talar dome lesions, medial malleolar osteotomy is necessary in some cases. Many operative techniques including transverse, oblique, inverted V-shape, crescentic and step-cut osteotomies of the medial malleolus have been described previously. But their techniques have several problems such as nonunion, rotation and limited access to lesions. So we introduce the new reverse chevron medial malleolar osteotomy which provides excellent access to lesions, good stability and a broad cancellous surface for rapid healing.

Os trigonum syndrome is a clinical disorder characterized by posterior ankle pain which occurs in excessive plantar flexion. The pain is elicited by the impingement of os trigonum between the calcaneus and the posterior edge of tibial plafond. Mostly, symptoms can be improved with nonsurgical management, however surgery is required for refractory cases. We report of a case of os trigonum syndrome in a female ballet dancer, which was successfully treated with subtalar arthroscopic excision of os trigonum.

Pigmented villonodular synovitis (PVNS) is a rare proliferative disease affecting joint synovium, tendon sheaths, bursae. The usual treatment for PVNS is a surgical excision. If destructive joint lesions have occurred, complete resections must be performed followed by arthrodesis or arthroplasty. We report a case of a pigmented villonodular synovitis involving an ankle joint which was treated by total ankle replacement for recurrence after simple synovectomy.

In this report, a case of a 70-year-old man with a large ganglion cyst formed after anterior transposition of the left ulnar nerve is presented. Three months after the index surgery, the patient presented with a painless superficial ovoid, soft mass measuring $5{\times}4{\times}2cm$ in size located at the posteromedial aspect of the left elbow, the previously operated site. Magnetic resonance imaging showed a well demarcated cystic mass with a stalk connecting to the elbow joint. Excisional biopsy was performed and pathologic findings showed that the cystic wall had no definite lining cells with myxoid degeneration compatible with findings of ganglion cyst.

This study suggests isolated Type IV-MO or Type IV-LO fractures could be treated with nonsurgical treatment because they do not interfere with normal elbow kinematics. Valgus and external rotation instability were influenced by total articular surface, however, posterior and proximal translation were influenced by isolated articular surface involvement of coronoid. Further clinical studies are warranted to validate these in vitro findings.
