ABSTRACT
A medial opening wedge supramalleolar osteotomy (SMO) introduced by Takakura et al. is a useful realignment procedure for patients with ankle joint arthritis and varus malalignment by shifting the weight-bearing axis laterally and redistributing the loads on the ankle joint. When pain persists after arthroscopic microfracture in patients with medial osteochondral lesion of the talus (OLT), redo arthroscopy, osteochondral autograft transplantation, autologous chondrocyte implantation, or matrix-induced chondrogenesis might be indicated. On the other hand, there is insufficient scientific evidence for realignment surgery through SMO, while the effect of realignment surgery has been studied consecutively for osteochondral lesions of the knee. Therefore, this paper reports a patient with medial OLT who underwent redo arthroscopy combined with SMO for persistent pain after primary arthroscopic microfracture.
ABSTRACT
During bone tumor resection, many cases require medial malleolar osteotomy to achieve adequate access to the operative field. Various osteotomy methods have been developed to address this issue, including oblique, transverse, reverse V-shape, and step-cut osteotomies.However, medial malleolar osteotomy has several drawbacks, such as the excessive disruption of the joint surface, unstable screw fixation when fixing the medial malleolus, and iatrogenic medial ankle joint arthritis due to articular displacement during the reduction of the osteotomy site. In addition, there is a possibility of injury to the posterior tibial artery, tibial nerve, or posterior tibialis tendon if the osteotomy range is too aggressive. Therefore, the authors propose a new osteotomy method, which has shown promising clinical results, namely, partial posterior medial malleolar osteotomy. This method minimizes articular involvement and provides adequate access to the operative field during talar body bone tumor resection.
ABSTRACT
Background@#The purpose of this study was to evaluate the association of body mass index (BMI) and waist circumference (WC) with the risk of Achilles tendinopathy (AT) or Achilles tendon rupture (ATR), using data from a nationwide population-based cohort.We hypothesized that higher BMI and WC would be independently associated with the increased risk of AT or ATR. In addition, a higher WC may potentiate the association between BMI and the risk of Achilles tendon problems. @*Methods@#We used the National Health Insurance database that covers the entire South Korean population to follow up subjects who participated in the National Health Screening Program (NHSP) from January 2009 to December 2010. The NHSP data include subjects’ BMI, WC, blood test results, blood pressure, and information about lifestyle. Among the subjects, those who were newly diagnosed as having AT or ATR before December 31, 2017, were selected. To examine the association of the variables with the risk of AT or ATR and determine whether the effect of higher BMI varied according to WC, multivariate Cox proportional hazards regression was used. @*Results@#Among a total of 16,830,532 subjects, 125,814 and 31,424 developed AT and ATR, respectively. A higher BMI showed a greater association with the increased risk of ATR than AT (adjusted hazard ratio [HR], 3.49 vs. 1.96). A higher WC was associated with the increased risk of AT (adjusted HR, 1.22), but not ATR. In a separate analysis, the association between BMI and the risk of AT was higher when subjects had higher WC as compared to those with lower WC, being most significant in individuals with both higher BMI and higher WC. @*Conclusions@#Higher BMI was more associated with the increased risk of ATR than AT. Moreover, a high central fat distribution played an independent and potentiating role in the development of AT. This implies the greater importance of a high central fat distribution contributing to the development of AT in obese people.
ABSTRACT
Quinolone antibiotics are frequently prescribed for suspected respiratory or urinary tract infections because of their effectiveness and generally perceived safety profile. On the other hand, some studies have raised concerns regarding the potential association between quinolone use and Achilles tendinopathy or tendon rupture. There is a lack of reports on the link between quinolone use and multiple tendon and tendon attachment site pain in the foot and ankle joints; hence, this study examined this issue further. This paper presents a case report of a patient with persistent Achilles tendinopathy and multiple tendon and tendon attachment site pain in the foot who did not respond adequately to conservative treatments. In particular, the discontinuation of quinolone use resulted in favorable clinical outcomes. This report offers valuable insights into the potential risks associated with quinolone antibiotics and highlights the importance of vigilance when managing patients with tendon-related complaints. A comprehensive review of the relevant literature is also presented to contextualize these findings.
ABSTRACT
The current SARS-CoV‑2 coronavirus disease 2019 (COVID-19) pandemic has been a particular challenge for diabetes patients. Since these patients are at a higher risk of COVID-19, they have been prioritized for vaccination. In this report, we describe the case of a patient scheduled for diabetic foot amputation who received the first dose of ChAdOx1 nCov-19 vaccine and subsequently developed severe purpura in his genitalia and both of his hands and feet, accompanied by acute renal failure. The operation had to be postponed as severe limb purpura appeared just before the operation. With adequate management for acute renal failure and topical steroid application for the severe purpura lesions, a successful outcome could be obtained after the delayed first ray amputation. We recommend that COVID-19 vaccination should be carefully administered in patients with a diabetic foot requiring amputation.
ABSTRACT
Peroneal tendon disorders are one of many causes of chronic lateral ankle pain. They are related to chronic conditions and anatomical factors and can cause persistent pain and functional impairment if neglected. Peroneal tendon tears are frequently misdiagnosed due to the absence of clear symptoms. For subacute or chronic peroneal tendon ruptures, tendons often became irreparable, and hence various surgical options have been introduced to address this issue. Current surgical treatment options include debridement and tubularization, tenodesis, tendon transfer, and reconstruction with a graft. There have been a few reports on the use of reconstruction techniques with an allograft. In this report, we present a rare case of a peroneal tendon reconstruction technique using an allograft in a young male with simultaneous irreparable peroneus longus and a complete rupture of the brevis tendon. The management plan, prognostic outlook, and a subsequent review of the relevant literature are also presented.
ABSTRACT
More than 120 surgical methods for the correction of hallux valgus deformities have been reported. For the correction of moderate to severe hallux valgus deformities with aesthetic demands, minimally invasive surgery at the proximal area can be considered. This paper reports a case of moderate hallux valgus deformity treated by a minimally invasive proximal transverse metatarsal osteotomy followed by intramedullary plate fixation.
ABSTRACT
Background@#This review aimed to evaluate the effects of corticosteroid injections on Morton’s neuroma using an algorithmic approach to assess the methodological quality of reported studies using a structured critical framework. @*Methods@#Several electronic databases were searched for articles published until April 2020 that evaluated the outcomes of corticosteroid injections in patients diagnosed with Morton’s neuroma. Data search, extraction, analysis, and quality assessments were performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and clinical outcomes were evaluated using various outcome measures. @*Results@#With 3–12 months of follow-up, corticosteroid injections provided satisfactory outcomes according to Johnson satisfaction scores except in two studies. Visual analog scale scores showed maximal pain reduction between 1 week and 3 months after injection. We found that 140 subjects out of 469 (29.85%) eventually underwent surgery after receiving corticosteroid injections due to persistent pain. @*Conclusions@#Corticosteroid injections showed a satisfactory clinical outcome in patients with Morton’s interdigital neuroma although almost 30% of the included subjects eventually underwent operative treatment. Our recommendation for future research includes using more objective outcome parameters, such as foot and ankle outcome scores or foot and ankle ability measures. Moreover, studies on the safety and effectiveness of multiple injections at the same site are highly necessary.

ABSTRACT
Heterotopic ossification is the formation of extra-skeletal bone in the muscle and soft tissues, and an osteoma is a benign bone-forming tumor composed of compact or mature trabecular bone limited almost exclusively to the craniofacial bones. This paper reports an extremely rare case of heterotopic ossification mimicking an osteoma that occurred independently at the plantar side of the medial sesamoid bone. The patient was a 46-year-old male with a three-month history of pain and a hard mass on the plantar aspect of the left forefoot sole. After excising the lesion, the patient’s symptoms were relieved, and no pain or complications occurred. This paper discusses this exceedingly rare case of heterotopic ossification around the medial sesamoid bone with a review of the relevant literature.
ABSTRACT
A postoperative hallux varus deformity is a dreaded complication of hallux valgus surgery. Several surgical options have been introduced to overcome this problem. This paper reports an uncommon case of a 68-year-old female patient who presented with a postoperative hallux varus deformity combined with a rupture of the flexor hallucis longus (FHL) tendon. She was treated successfully by a minimally invasive correctional osteotomy with open tenorrhaphy. With experience in treating this complicated case, it was noted that FHL could be transected during the trans-articular adductor tenotomy. Hence, extra caution is needed when the degree of hallux valgus deformity is excessive. To the best of the author’s knowledge, correctional valgization osteotomy for a postoperative hallux varus deformity in a minimally invasive manner has not been reported. This case report is expected to benefit surgeons and their patients with severe hallux valgus deformity.
ABSTRACT
Chondroblastoma is a rare benign tumor that produces giant cells and cartilage matrix. The tumor occurs in people between 10 and 25 years with slightly higher incidence in males. The condition occurs in the proximal epiphysis of the tibia and humerus, distal epiphysis of the femur, but its occurrence in the talus is relatively rare, accounting for 4% of the total number of chondroblastoma cases. Chondroblastoma is often misdiagnosed as a primary aneurysmal bone cyst, giant cell tumor, chondromyxoid, and lesion of a secondary aneurysmal bone cyst by fibrous dysplasia. The most commonly used surgical method for chondroblastoma is broad curettage with bone grafting. In general, an aneurysmal bone cyst is associated with a second degree chondroblastoma, which is approximately 20%. Chondroblastoma of the talus and secondary aneurysmal bone cysts can be misdiagnosed as primary aneurysmal bone cysts. This paper reports a case of a young male patient with chondroblastoma of the talus, which was initially misdiagnosed as an aneurysmal bone cyst with involvement of the talo-navicular joint.

According to a recent systemic review, hallux valgus deformity has a prevalence rate of about 23% among adults aged 18 to 65 years. To date, more than 100 operative methods have been reported for the correction of hallux valgus deformity. For young female with mild to moderate hallux valgus deformity, minimally invasive surgery can be considered for aesthetic demands. Here, we report a case of a young female patient with mild hallux valgus deformity treated by minimally invasive surgery using intramedullary low profile plate fixation. This can be the favorable method for secure fixation of the osteotomy site and prevention of medial skin irritation symptoms derived from a sharp osteotomy margin.

Nearly one third of the world's population have active or latent tuberculosis, resulting in 1.5 million deaths annually. Tuberculosis involving the peripheral nerve is difficult to detect. Sural nerve tuberculoma is an extremely rare case of tuberculous involvement of the peripheral nerve that has attracted the attention of physicians. This paper reports a patient with sural nerve tuberculoma. A 58-year-old female patient presented with a palpable mass on the posterolateral calf with progressive tingling sensation on the distal area. The patient had no history of trauma and it was unclear whether the patient had any contact with individuals with active tuberculosis. The histopathologic findings revealed a granuloma-like lesion with caseous necrosis that was compatible with tuberculoma.

An osteochondral fracture is considered to be an injury involving the cartilage and subchondral bone. Acute traumatic osteochondral fractures can be related to joint instability because abnormal joint motion causes shearing and rotatory stress. Acute osteochondral fractures are frequently missed or misdiagnosed as a pure soft tissue injury. Thus, surgeons' proactive attention is highly required as articular cartilage has limited potential for self-repair and these lesions may develop osteoarthritis. In order to minimize the progression of post-traumatic osteoarthritis, it is important to properly identify and treat osteochondral fractures. Yet, little is known about the operative management of acute osteochondral fractures of the talus. We report here on a case of a middle-aged male with acute osteochondral fractures of the bilateral lateral talar dome. We applied different operative methods on each side with regard to fragment size and stability. A favorable clinical outcome was obtained at 18 months follow-up.
ABSTRACT
Pigmented villonodular synovitis (PVNS) is a proliferative disease that affects the synovial joint, tendon and bursa. PVNS can form a nodular structure in any joint, but it most commonly affects the knee joint and is rare in the foot and ankle joint. PVNS is divided into two types. Localized-type PVNS exhibits focal involvement with a nodular mass, while diffuse-type PVNS involves the entire synovium. Synovitis of the affected joint can also destroy cartilage and bone. Diffuse type accounts for 75% of PVNS and has a reported recurrence rate of 12.2% to 46%; aggressive synovectomy is recommended as the most effective treatment. In localized-type PVNS, only arthroscopic partial synovectomy is effective with a lower recurrence rate. We report a patient with severe ankle joint arthritis induced by diffusetype PVNS. The patient was treated by lateral malleolar ostectomy and ankle arthrodesis with a plate and screws via a lateral approach.

A hypertrophied peroneal tubercle can present as a bony prominence at the lateral aspect of the foot and a peroneal tenosynovitis or tear. We report a case of a 52-year-old man complaining of lateral foot tingling pain and numbness. The sural nerve entrapment and peroneus longus tenosynovitis by hypertrophied peroneal tubercle were confirmed. Good results were obtained after excision of the hypertrophied peroneal tubercle and sural nerve release.

PURPOSE: To analyze the correlation between a rupture of the hypovascular zone and early single heel raising after Achilles tendon repair. MATERIALS AND METHODS: From January 2012 to August 2015, 68 patients, who underwent surgical treatment for a Achilles tendon rupture using Krackow method, were analyzed retrospectively. The patients were divided into two groups according to possibility of single heel raises within 3 months postoperatively. During the periodic outpatient observations, the visual analogue scale, Achilles tendon total rupture score (ATRS), and timing capable single heel raises were evaluated. In addition, the preoperative defect size and distance between the calcaneal osteotendinous junction and the rupture site were measured by ultrasound in all cases. RESULTS: Twenty-three patients could perform a single heel raise within 3 months after surgery (early single heel raise group), and forty-five patients could perform a single heel raise after 3 month postoperatively. The age, gender, body mass index, smoking, and operation delay were similar in the two groups. In addition, the defect size and distance between the calcaneal osteotendinous junction and rupture site as measured by preoperative ultrasound were similar (p=0.379 and p=0.631, respectively). On the other hand, when the rupture site was divided into the hypovascular zone (4~7 cm from calcaneal osteotendinous junction) and non-hypovascular zone, the hypovascular zone rupture rate was significantly lower in the early single heel raise group (60.9%, 14/23; 91.1%, 41/45; p=0.003). In logistic regression analysis, the odds of the hypovascular zone rupture group being capable of early single heel raise were 0.189 (p=0.017). The ATRS score at 3 months and 1 year after surgery were significantly higher in the early single heel raise group (p < 0.001). CONCLUSION: Achilles tendon rupture at the hypovascular zone is a poor prognostic factor for early single heel raise and might affect the prognosis significantly after an Achilles tendon rupture operation.
