Humerus shaft fracture is a frequent injury in orthopedic practice and generally occurs through direct or indirect trauma. Indirect trauma mechanisms of humerus shaft fractures are mostly related with arm wrestling or throwing activities. Recently, the population enjoying wakeboard are increasing, and the humeral shaft fracture can occur during wakeboarding. We report a case of humerus shaft fracture occurring during wakeboarding trick, which was treated successfully using plate osteosynthesis.

The fracture of the humerus during arm wrestling are uncommon, but may occur in the shaft or medial condyle. In the shaft of humerus, the fractures are usually spiral and between the middle and distal third, with or without neurological involvement. A case of a comminuted spiral fracture with butterfly fragment of the distal third of the humerus is reported which had occurred during arm wrestling and was treated by open reduction and internal fixation. The possible mechanism of injury and the question of treatment are discussed.

We report three cases of kerion celsi caused by Trichophyton tonsurans in 16-year-old students of one high school wrestling team. The first case presented a 10x5cm and several 3~4cm sized, markedly inflammatory, boggy lesions on the scalp for 5 months. Other cases showed several 2~4cm sized, erythematous, follicular pustules and nodules with partial alopecia on the scalp for 2 months. Histopathology and results of mycologic study were consistent with kerion celsi due to Trichophyton tonsurans. All lesions were successfully treated with griseofulvin 500mg daily for 7~15weeks and short term therapy of low dose of prednisolone and cephadroxil.

PURPOSE: To evaluate the mechanism of the humeral fractures induced by arm wrestling and the clinical results of its treatment. MATERIALS AND METHOD: We reviewed 7 humeral fractures induced by arm wrestling; 3 humeral shaft fractures, 4 humeral medial epicondyle fractures. The mechanism of the fractures and the clinical results were assessed by history and radiographs. RESULTS: Shaft fractures were produced by twist and axial compression force. Humeral medial epicondyle fractures were the avulsion fractures by excessive contraction of flexor muscles and developed in young age. We operated 6 of them and in all cases, we could obtain fracture healings without complication. CONCLUSION: The humeral fractures induced by arm wrestling have the differences in the ages and mechanisms as to the locations of the fractures and if the proper treatment is performed, the clinical results are satisfactory.

BACKGROUND: Soil is one of the major habitats of fungi. Keratinophilic fungi are an important group of fungi that live in soil, some of which are potential pathogens for humans and animals. OBJECTIVE: The aim of this study was to isolate and identify keratinophilic fungi near Korean wrestling fields, playgrounds, and beauty salons. METHODS: We visited 5 Korean wrestling fields, 15 playgrounds, and 10 beauty salons in Daegu, Korea, from July to August 2015. Soil samples were divided into 3 groups according to the distance from Korean wrestling fields, playgrounds, and beauty salons: near, 10 m, and 100 m. RESULTS: Of 185 soil samples examined, 60 (32.4%) yielded keratinophilic fungi. Specifically, of the 125 samples around Korean wrestling fields and playgrounds, isolation rates were 37.7% (17/45) at the near distance, 27.5% (11/40) at 10 m, and 0% at 100 m. Of the 60 samples around beauty salons, isolation rates were 85% (17/20) at the near distance, 75% (15/20) at 10 m, and 0% at 100 m. Near Korean wrestling fields, playgrounds, and beauty salons, Penicillium spp. were the predominant species (16.9%, 11/65), followed by Fusarium spp. (13.8%, 9/65), Purpureocillium spp. (12.3%, 8/65), Microsporum spp. (6.1%, 4/65), Chrysosporium spp. (3.1%, 2/65), and other species. CONCLUSION: In this study, isolation rates of keratinophilic fungi were higher in the soil closer to the Korean wrestling fields, playgrounds, and beauty salons. Especially near beauty salons, we found keratinophilic fungi in most soil samples. We should be aware of these results and pay attention to eliminate hair or keratins in soils.

Trichophyton tonsurans has been the main agent of tinea capitis in the United States since 1950s. In Korea, dermatophytosis due to Trichophyton tonsurans has begun to be reported since 1995. These Korean cases were all confined to wrestlers. We report eight patients with dermatophytosis due to Trichophyton tonsurans, Seven of them were middle-school wrestlers and the other, a six-year-old boy, was a non-wrestler. The infection of the wrestler patients was known to have originated from contact with infected persons during wrestling competitions. The source of Trichophyton tonsurans in the boy patient was obscure. To our knowledge, tinea capitis caused by Trichophyton tonsurans in a non-wrestler Korean has not been reported previously.

We report a case of kerion celsi caused by Trichophyton(T.) tonsurans in a 14-year-old student of a middle school wrestling team. The lesion was on the scalp for 1 month and 6.5X5.0X1.0 cm sized, markedly inflammatory, swollen, boggy pus exuding plaque. Culture from the scalp lesion of the patient on Sabouraud dextrose agar showed T. tonsurans. The patient was treated with 250 mg of terbinafine daily for 12 weeks and short term therapy of low dose of prednisolone. Skin lesions were completely cured and recurrence is not observed to date.

Humeral shaft fracture sustaining arm wrestling is rare, but occurs intermittently. We treated 15 cases of humeral shaft spiral fractures occurred during arm wrestling for fun since 2007. Average age was 22.47±2.69 years, average body mass index was 22.67±2.06 kg/m2. There was no prominent tendency for the fractures to occur at a certain phase of the match. Fractured level and length of each case were measured in the plain radiographs and compared with those of previous reports. Eight cases (53.3%) had an associating medial butterfly fragment, and the time taken until the fracture occurred was longer than that of simple spiral fracture (15.62±9.03 seconds vs. 7.85±2.67 seconds, p=0.048). Fractures were distributed mid to distal one third of humerus, the length of fracture was 7.93±2.69 cm and involved 25.43%±8.24% of humeral length. All cases except one treated surgically using plate and screws and returned their full activities within postoperative 3 months. Although arm wrestling is a simple and joyful sport, participants should be aware of the risks of injury during arm wrestling, especially for the amateur players.

Fractures of the shaft of the humerus due to muscle violence esp. from throwing hand grenades are uncommon. Even so there are reports from many authors documenting such fractures from throwing a javerin, baseball, hand grenade and arm wrestling. Fractures of this type are usually spiral in nature; located between the middle and distal third of the humerus. We have treated four such cases during activities in which hand grenades were thrown. These fractures were sustained by military recruits in the Department of Orthopaedic Surgery, Capital Armed Forces General Hospital from Jan. 1980 Dec. 1980.
