BACKGROUND: This study assessed the average time to return to training and official game participation after modified Broström operation (MBO) in elite athletes. METHODS: Sixty athletes diagnosed with lateral ankle instability underwent MBO from October 2011 to December 2013. Their average age was 19.3 years, and the average follow-up time was 28.8 months. We measured the time sequence of three phases of rehabilitation: start of personal training, start of team training, and start of the first official game after recovery. Patients were divided into an early return to play (RTP) group and late RTP group. The groups were compared to identify possible risk factors affecting the RTP time. RESULTS: The mean length of time to return to personal training was 1.9 months, return to team training was 2.9 months, and return to competitive play was 3.9 months. There were no significant differences of any variables including age, sex, body mass index, level of sports, grade of instability, presence of os subfibulare, and preoperative functional score between the early RTP and late RTP groups. CONCLUSIONS: The RTP was 83.3% at 4 months after lateral ankle ligament repair and 100% at 8 months postoperatively. The results provide reference data for orthopedic surgeons in evaluating surgical results and informing patients about expectations after surgery in terms of performance level and timing of return to sports.

The purpose of this study was to investigate the ultrasonographic features of flexor hallucis longus (FHL) tenosynovitis in sports players. High-resoluted ultrasound was used to measure the thickness and echogenicity of the flexor hallucis longus at the posteromedial ankle, especially the fibro-osseous tunnel, for 60 sports players (120 feet). They were compared with their asymptomatic feet. There were two group; group 1 was symptomatic feet, 2 was asymptomatic. The 36 males (72 feet) and 24 females (48 feet) had an average age of 21.3 years (range, 18.23 years). Thickness, echogenicity of the tendon on each group were evaluated by the ultrasonography and the results were statistically analyzed. The mean thickness of the FHL on group 1 was 3.4+/-1.2 mm, 2.1+/-1.3 mm on group 2. There was significant difference between two groups (p=0.002). The thickness of FHL based on gender and location was not significant different (p>0.05). For group 1, increased thickness of the FHL and reduced echogenicity, peritendious fluid collection were observed in ultrasonographic findings.Increased thickness (>3 mm) and hypoechoic lesion, peritendinous fluid collection of the tendon were sonographic findings at the posteromedial ankle in the FHL tenosynovitis. The authors suggested that Ultrasonography is a valuable and alternative tool for the evaluation of FHL tenosynovitis.

From a biomechanical standpoint, the main pathologic abnormality of fifth metatarsal stress fracture is the location where repetitive tensile stress concentrated. Decreasing tensile force in this region would be a proper treatment. Therefore, the purpose of this study is to evaluate the precise sagittal and coronal location of the fifth metatarsal stress fracture. Between June 2012 and May 2013, 38 athletes with a fifth metatarsal stress fracture were treated. To evaluate the precise sagittal location of the fracture, the entire length of the fifth metatarsal was measured and the distance from tuberosity to the fracture line was measured. To evaluate the precise coronal location of the fractures, coronal computed tomography images were obtained for incomplete fracture cases. The fracture location was classified as four quadrants. Thirty patients were classified into zone III fracture. However, the fracture is located in zone II for remaining eight cases. The median value of ratio between whole length and the distance from tuberosity to the fracture was 0.35 (range, 0.29–0.40) Among 33 incomplete fracture cases, there were 28 patients whose fracture developed in plantolateral quadrant, four patients at the lateral side and a patient for plantar side. The main pathologic abnormality is at the plantar lateral side because of the repetitive stress concentrated there.

Fractures located at the metaphyseal/diaphyseal junction at the base of the fifth metatarsal were first described by Sir Robert Jones in 1902. However, ever since, there has been disagreement and debate regarding the diagnosis, classification, pathomechanics, the incidences, and potential causes of delayed unions and nonunions, and the optimal method of treatment. It appears to be widely agreed that proximal fractures of the metaphyseal/diaphyseal region of the fifth metatarsal are prone to delayed union or even nonunion. Several classifications of proximal fifth metatarsal stress fractures have been devised. Torg et al. classified fractures involving the proximal part of the diaphysis of the fifth metatarsal into three types. The Torg classification is a good grading system that can be used to determine the type of surgery needed as well as for the prediction of prognosis. The "plantar gap" might add to the decision-making process for surgery and improve the prediction of patient prognosis. In addition, the new classification using 'plantar gap' might be used for classification of fifth metatarsal stress fracture. Fifth metatarsal stress fractures can be treated conservatively or surgically, and excellent results have been reported for surgery with rapid recovery in athletes. Intramedullary screw fixation has become a popular form of fixation for fifth metatarsal stress fractures. Bone grafting presents the problems of a longer recovery time and additional skin incision for harvesting. The modified tension band wiring is an useful and simple option for surgical treatment of challenging fifth metatarsal stress fractures.

The purpose of this study was to evaluate the clinical results of surgical excision of symptomatic nonunion of fifth metatarsal base avulsion fracture in athletes. From February 2008 to December 2009, six athletic patients who had a symptomatic nonunion of fifth metatarsal base avulsion fracture underwent surgical excision of ununited bony fragment and they were followed for more than 12 months. The mean age was 18.5 years and the mean follow-up period was 13 months. The clinical results were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) forefoot scoring system and Visual Analogue Scale (VAS) scoring system and statistically analyzed (SPSS ver. 18.0). The AOFAS and VAS score was improved in all patients. The mean AOFAS forefoot score was improved from 58.6+/-5.7 preoperatively to 95+/-5.4 postoperatively, which indicated significant difference (p=0.024). The mean preoperative VAS score was 8.0+/-0.6 and the mean postoperative VAS score was 1.6+/-0.5 cm, which indicated significant difference (p=0.023). There were no postoperative problems and functional loss on the operation lesions. The surgical excision of symptomatic nonunion of fifth metatarsal base avulsion fracture in athletes was found to be one of the ideal treatment option for early return to full activity and relief of pain.

Occurrence of pseudoaneurysm in the foot and ankle is rare, and is usually caused by traumatic injury or by iatrogenic intervention. Iatrogenic pseudoaneurysms in the foot and ankle have been observed after rearfoot and ankle fusions, ankle arthroscopy, endoscopic and open plantar fasciotomy, tibial osteotomy with limb lengthening, midfoot amputation, and Lapidus procedure. We report on a patient who developed a pseudoaneurysm of the dorsal metatarsal artery following correction of hallux valgus. The patient underwent proximal chevron osteotomy and Akin phalangeal osteotomy. The feeding artery was ligated and the pseudoaneurysm was excised.

BACKGROUND: The increasing rate of drug-resistant tuberculosis (TB) is a threat to the public health and TB control. In Korea, about 75~80% of TB patients are treated in private hospitals and the rate has been continuously increasing since 2000. METHODS: On a retrospective basis, we enrolled 170 newly diagnosed with or retreated for multidrug-resistant TB (MDR-TB) in 2004 from 21 private hospitals. We extracted the following demographics and treatment history from patient medical records: initial treatment outcomes, cumulative survival rates, treatment outcomes, and prognostic factors. RESULTS: Of the 170 patients, the majority were male (64.1%), the mean age was 44.5 years old, and mean body-mass-index was 20.2 kg/m2. None of the patients tested positive for HIV. Eleven (6.5%) were confirmed to have extensively drug-resistant TB (XDR-TB) at treatment initiation. Treatment success rates were not different between XDR-TB (36.4%, 4/11) and non-XDR MDR-TB (51.6%, 82/159). Default rate was high, 21.8% (37/170). Far advanced disease on X-ray was a significant negative predictor of treatment success; advanced disease and low BMI were risk factors for all-cause mortality. CONCLUSION: In private hospitals in Korea, the proportion of XDR-TB in MDR-TB was comparable to previous data. The treatment success rate of MDR-/XDR-TB remains poor and the failure rate was quite high. Adequate TB control policies should be strengthened to prevent the further development and spread of MDR-/XDR-TB in Korea.
