Sinding-Larsen-Johansson disease

Childhood and adolescent sports participation is encouraged because of health and wellness benefits. However, the increasing number of young athletes means there is the potential for more sports-related overuse injuries. Most youth sports injuries occur at the bone's relatively weaker growth centers: the epiphyses and apophyses. Little league shoulder and elbow are common overuse injuries in baseball and other single-arm dominant sports. Little league shoulder is a Salter-Harris fracture of the proximal humerus, and little league elbow is an apophysitis of the medial epicondyle...

Osgood-Schlatter disease (OSD) and Sinding-Larsen-Johansson disease (SLJD) are commonly diagnosed conditions in young, athletic patients who present with anterior knee pain. Despite the familiarity many clinicians have with OSD because of its frequent diagnosis, it does not differ much from SLJD in clinical presentation. Although these diseases generally are self-limiting, diagnostic imaging studies can help clinicians make the correct diagnosis, helping patients avoid progressing to advanced disease states that would require extended rest time, prolonged pain, and potential surgical intervention...

Sinding-Larsen-Johansson syndrome is an osteochondrosis affecting the inferior pole of the patella. Most cases can be easily diagnosed with adequate clinical history, physical examination, and proper imaging, including conventional radiography, ultrasound, and magnetic resonance imaging. Differentiating this condition from patellar sleeve avulsion fractures is important, since treatment is frequently surgical in the latter. Overlap between these two conditions can also occur. We present a case of an 11-year-old boy, with Sinding-Larsen-Johansson syndrome on both knees and a minimally displaced acute patellar avulsion sleeve fracture of the left knee, which was treated conservatively...

Traction apophysitises are a well-known entity in the orthopedic world that are generally thought of as conditions of the pediatric population secondary to overuse and repetitive microtrauma. Many have been named for their original descriptors, and therefore the purpose of this review is to highlight the backgrounds of these physicians, pay tribute to those who came before, and standardize the definitions of these oft-used eponyms. Iselin's disease, Little League Elbow, Osgood-Schlatter disease, Sever's disease, and Sinding-Larsen-Johansson disease will be discussed in brief, followed by a historical background presenting the original description of the named author as well as a short biography...

This history page in the series "Leaders in MSK radiology" is dedicated to the memory and achievements of the Norwegian physician Christian Magnus Falsen Sinding-Larsen who's name is connected to the medical eponym Sinding-Larsen-Johansson disease.

We report a case of a 12-year-old boy who presented with infrapatellar pain, with subsequent diagnosis of traction apophysitis of the knee (Sinding-Larsen-Johansson disease). Conventional radiographs are frequently reported with no significant findings in the acute setting, leading to ultrasound as the modality of choice for diagnostic efficacy of apophyseal traction injuries in young athletes. Sinding-Larsen-Johansson disease has a 2%-5% incidence in children aged 10-15 years, with the most common cause related to sporting activities related to jumping...

OBJECTIVES: Diagnosis of Sinding-Larsen-Johansson disease may not be an easy task. Several sport-related conditions affect the distal pole of the patella in the adolescent, and treatment varies considerably. The article describes a patient that had radiographic features of Sinding-Larsen-Johansson disease associated with an atypical acute presentation. METHODS: Case report and literature review. RESULTS: A 10-year-old boy presented with a sudden pain after a noncontact soccer injury...

One of the most common knee injuries is ligament tear, which may initially manifest as an osseous injury in radiographs. Radiologists should therefore be able to recognize ligament tears of the knee as osseous abnormalities in images. This review focuses on the imaging features of knee ligament injuries and their related osseous injuries: anterior cruciate ligament (ACL) tear with Segond fracture; associated marrow contusion; ACL avulsion fracture; posterior cruciate ligament (PCL) tear with osseous avulsion of the ligament including arcuate sign; reverse Segond fracture; PCL avulsion fracture; medial collateral ligament tear with Pellegrini-Stieda disease; lateral collateral ligament tear with avulsion fracture of the fibular head; and patellar ligament injuries with Osgood-Schlatter and Sinding-Larsen-Johansson...

The most common cause of adolescent heel pain is calcaneal apophysitis also known as Sever's disease. The condition may occur in adolescent athletes, particularly those involved in running or jumping activities, during the pubertal growth spurt. The mean age of presentation in Sever's disease is ten, (range 7-15). It presents with posterior heel pain that is worse with activity and relieved by rest in most cases. Sever's disease, Osgood Schlatter's disease (tibial tuberosity) and Sinding-Larsen Johansson syndrome (distal patella) are all overuse syndromes brought about by repetitive submaximal loading and microtrauma...

Athletes sometimes experience overuse injuries. To diagnose these injuries, ultrasonography is often more useful than plain radiography, computed tomography (CT), or magnetic resonance imaging (MRI). Ultrasonography can show both bone and soft tissue from various angles as needed, providing great detail in many cases. In conditions such as osteochondrosis or enthesopathies such as Osgood-Schlatter disease, Sinding-Larsen-Johansson disease, bipartite patella, osteochondritis dissecans of the knee, painful accessory navicular,and jumper's knee, ultrasonography can reveal certain types of bony irregularities or neovascularization of the surrounding tissue...

Primary care practitioners are in a position to educate patients and parents about the risk factors that may increase the incidence of knee pain in adolescent females. This article highlights patellofemoral pain syndrome, Sinding-Larsen-Johansson syndrome, Osgood-Schlatter disease, and meniscal tears.

OBJECTIVE: To investigate the prevalence of osteochondrosis in children and adolescent soccer players. MATERIALS AND METHODS: A questionnaire was distributed to players of all 113 junior soccer teams participating in a regional summer championship in August 2012 inquiring about pain in the body during or after training or a match. Physical examination of the lumbar spine or legs was recommended to players who complained of pain on the questionnaire, and for those who had positive findings on the physical examination, radiographic or ultrasonic examination at our hospital was recommended...

Lower limb traction apophysitis is common in young athletes, occurring at sites such as the tibial tubercle (Osgood-Schlatter disease) and distal patella (Sinding-Larsen-Johansson disease). Around the hip, iliac apophysitis is well recognized, but no cases of greater trochanter apophysitis have previously been reported. We describe the case of a 15-year-old male basketball player with a 2-month history of the right hip pain and significant functional limitation. X-rays revealed widening of the greater trochanter apophysis with subchondral sclerosis, consistent with a diagnosis of traction apophysitis...

BACKGROUND: An estimated 30 to 40 million school children participate in sports in the United States; 34% of middle-school participants become injured and seek medical treatment at an annual cost close to $2 billion. The purpose of the current study was to evaluate the injury incidence and rates in female athletes in the middle-school setting during the course of 3 seasons. METHODS: Female basketball, soccer, and volleyball players were recruited from a single county public school district in Kentucky consisting of 5 middle schools...

OBJECTIVES: To determine if sport specialization increases the risk of anterior knee pain in adolescent female athletes. DESIGN: Retrospective cohort epidemiology study. METHODS: Female basketball, soccer, and volleyball players (N = 546) were recruited from a single county public school district in Kentucky consisting of 5 middle schools and 4 high schools. A total of 357 multisport and 189 single-sport (66 basketball, 57 soccer, and 66 volleyball) athlete subjects were included due to their diagnosis of patellofemoral pain (PFP) on physical exam...

AIM: To analyse the clinical symptoms, aetiology and biomechanical aspects related to Sinding-Larsen-Johansson (SLJ) disease. MATERIAL AND METHOD: A case control study was conducted, analysing the following variables: age, gender, clinical follow up, side of body with the symptoms, sporting activity, radiological stage, presence of patella alta, presence of short hamstring tendons, and increased posterior tibial slope. RESULTS: A total of 15 knees in 14 patients were studied; one case with bilateral disease...

Overload syndromes are caused by repetitive microtrauma, and the knee joint is most frequently affected in adolescents. The reason for this is that the knee joint is engaged in almost all sports activities. Pathologies related to the anterior aspect of the knee are: femoropatellar pain, jumper's knee syndromes, Osgood-Schlatter disease, Sinding-Larsen-Johansson syndrome and patellar stress fractures; to the medial aspect: semimembranous tendon enthesopathy and pes anserinus bursitis; to the lateral aspect: iliotibial band syndrome (runner's knee), popliteus and femoral biceps tendon enthesopathy; to the posterior aspect: fabella syndrome and medial gastrocnemius muscle tendon enthesopathy...

Osgood-Schlatter disease is one of the most common causes of knee pain in active adolescents. It is a generally benign disturbance at the junction of the patellar tendon and the tibial tubercle apophysis, and treatment during its 12- to 24-month course should be matched to severity. Mild symptoms require only patient education and moderation of activity, but severe symptoms call for a period of rest (or, rarely, immobilization) followed by aggressive quadriceps strengthening. Other conditions such as Sinding-Larsen-Johansson disease may occur simultaneously, and long-term effects can include a prominence on the anterior knee or painful kneeling...

We examined radiographs of the inferior pole of the patella in seven juvenile athletes diagnosed as having Sinding-Larsen-Johansson disease (SLJD) and discussed the etiology of the syndrome. Eight knees had tenderness at the inferior pole of the patella accompanied by radiographic abnormalities. A regular or irregular calcification was found at the inferior pole of the patella in three knees; coalescence of the calcification was found in two knees; incorporation of the calcification into the patella to yield a normal radiographic configuration of the area was found in two knees; and a small calcification separated from the patella was found in one knee...
