Congenital orthopaedic limp deformities in Corpus Hippocraticum.

Int Orthop 2019 Feb 15. Epub 2019 Feb 15.

History of Medicine, Anatomy Department, School of Medicine, Democritus University of Thrace, Alexandroupolis, Greece.

During the fifth century BC in ancient Greece during the eve of orthopaedics, the Hippocratic School of Medicine diagnosed a series of congenital limb deformities. Congenital dislocation of the arm, elbow, wrist, hip, knee, tarsotibial joint, apex leg, as well as talipes valgus (clubfoot), congenital clavicle fractures, and thumb malfunction were all discussed by Hippocrates and his followers. Ancient Greek medico-philosophers, fond of a "perfect" human body, proposed an immediate non-interventional approach, while archaic orthotics and specialized footwear were suggested. Read More

Sporthopaedicum, Straubing and Regensburg, Bahnhofplatz, 27, 94315, Straubing, Germany.

Purpose: Most elbow dislocations can be treated conservatively, with surgery indicated in special circumstances. Surgical options, apart from fracture fixation, range from repair or reconstruction of the damaged ligaments to static external fixation, usually entailing either a long period of immobilization followed by carefully monitored initiation of movement or dynamic external fixation. In general, no consensus regarding surgical treatment has been reached. Read More

[Bony knee injuries in childhood and adolescence].

Unfallchirurg 2019 Jan;122(1):6-16

Unfallchirurgische Abteilung, Landeskrankenhaus Horn, Spitalgasse 10, 3580, Horn, Österreich.

While fractures around the knee are known to be rare, physicians have encountered a rise in the frequency due to the increased participation of children and adolescents in high-impact sports at a younger age. Even if the treatment of fractures in some cases resembles that in adults, the diagnostics and treatment in childhood and adolescence require a hígh level of experience in order avoid possible sequelae and to enable early recognition. Thorough diagnostics using clinical and imaging investigations as well as a precise weighing up of the treatment are essential to minimize differences in leg length and axial malpositioning of the leg.

[Patellofemoral instability in children and adolescents].

Unfallchirurg 2019 Jan;122(1):22-32

AUVA Traumazentrum Wien, Standort Meidling, Kundratstr. 37, 1120, Wien, Österreich.

Dislocation of the patella is one of the most common knee injuries in childhood and adolescence. After detailed clinical and radiological clarification, conservative functional treatment with special orthotic devices is most commonly applied in patients with a primary dislocation without concomitant injuries; however, the redislocation rate after conservative treatment has been reported in the literature to be between 35% and 70%, depending on the risk factors present. Therefore, numerous surgical treatment options exist which are sometimes again associated with high redislocation rates and others can lead to early arthrosis of the patellofemoral joint when used indiscriminately.

Factors Affecting Tibial Tuberosity-Trochlear Groove Distance in Recurrent Patellar Dislocation.

Clin Orthop Surg 2018 Dec 21;10(4):420-426. Epub 2018 Nov 21.

Center for Joint Disease, Chonnam National University Hwasun Hospital, Hwasun, Korea.

Background: The tibial tuberosity-trochlear groove (TT-TG) distance is used to determine the necessity of tibial tubercle osteotomy. We conducted this study to determine the extent to which each of the tibial tuberosity lateralization, trochlear groove medialization, and knee rotation angle affects the TT-TG distance in both normal and patella dislocated patients and thereby scrutinize the rationale for tuberosity transfer based on the TT-TG distance.

Methods: Retrospective analysis of rotational profile computed tomography was done for patella dislocated and control group patients. Read More

Knee 2019 Jan 29;26(1):273-278. Epub 2018 Nov 29.

Houston Methodist Othopedics & Sports Medicine, Houston, TX, United States of America. Electronic address:

Nail-patella syndrome (NPS) or hereditary onycho-osteodyaplasia is a rare genetic condition involving a mutation in the LMX1B gene affecting nails, elbows, knees, and pelvis. Due to the regulatory functions of the gene in many developmental processes through the body, patients with NPS experience wide-ranging musculoskeletal problems including patellar instability, fingernail anomalies, iliac exostoses/horns, and elbow abnormalities. The patellar changes often involve aplasia, hypoplasia, and chronic dislocation. Read More

Patellar Tendon-Lateral Trochlear Ridge Distance: A Novel Measurement of Patellofemoral Instability.

Am J Sports Med 2018 Dec 14;46(14):3400-3406. Epub 2018 Nov 14.

Division of Orthopaedics, Children's Hospital of Philadelphia, Philadelphia, Pennsylvania, USA.

Background:: Abnormalities in the trochlea-patella-tibia relationship have been shown to be risk factors for recurrent patellofemoral instability, although no current measurements quantify patellar containment in the trochlea. Standard measurements, such as tibial tubercle-trochlear groove (TT-TG) distance, do not account for the containment of the patella by the trochlea. Our goal was to develop a measurement to assess how well the trochlea contained the extensor mechanism. Read More
