Zentrum für Sportorthopädie, European SportsCare Network (ESN), Wiesbaden-Nordenstadt.

Background: Reattachment of the distal Achilles tendon to the posterior calcaneus following distal Achilles tendon tears/avulsions or after excision of large posterior heel spurs is a challenging task for the orthopaedic surgeon.

Patients/material And Methods: Between 2005 and the end of 2015, 22 patients who underwent repair/reconstruction of a lesion of the distal Achilles tendon were identified from our electronic records. Calcaneal reinsertions were performed following distal Achilles tendon tears/avulsions (n = 15) or following excision of a large symptomatic posterior heel spur (n = 7). Read More

Three-Dimensional computed tomography tunnel assessment of allograft anatomic reconstruction in chronic ankle instability: 33 cases.

Orthop Traumatol Surg Res 2018 Nov 27. Epub 2018 Nov 27.

Department of Orthopedic Surgery, Inje University Seoul Paik Hospital, Seoul, Korea. Electronic address:

Introduction: Although clinical results of anatomic reconstruction using allograft are reportedly good, studies on how accurately the tunnel has been made after surgery are very rare. The purpose of this study was to analyze the postoperative locations of the tunnels through 3-dimensional computed tomography (3D-CT) after anatomic ligament reconstruction and to evaluate its clinical results.

Hypothesis: We hypothesized that anatomic lateral ligament reconstruction could lead to excellent results in clinical outcomes by repositioning anterior talofibular ligament (ATFL) and calcaneofibular ligament (CFL) accurately. Read More

Is the Bohler angle reliable for operative reduction of calcaneus fracture?

J Orthop Sci 2018 Nov 21. Epub 2018 Nov 21.

Department of Orthopedic Surgery, Myongji Hospital, Hanyang University Medical Center, 697-24 Hwajung-dong, Deokyang-gu Goyang-si, Gyeonggi-do, 412-270, Republic of Korea. Electronic address:

Backgroud: To evaluate reliability of Bohler angle in doing operative reduction of fractured calcaneus, and compare its value over other image lines of hindfoot when surgeons determine whether the injured calcaneus is reduced close to pre-injured state.

Methods: Eighteen of postoperative lateral radiographs were obtained and edited with two versions; one of which anterior of calcaneus erased not to check Bohler angle, the other of which peri-calcaneus structure such as talus erased only to check Bohler angle. Four orthopaedic surgeons were asked to determine the two sets of images whether the injured calcaneus is reduced close to pre-injured state in independent two sessions. Read More

Three-Dimensional (3D) Computed Tomographic (CT) Assessment of the Sustentaculum Tail to Find Distinctive Characteristics: Implications for Surgery.

Med Sci Monit 2018 Nov 22;24:8417-8421. Epub 2018 Nov 22.

Department of Orthopedics, Affiliated Traditional Chinese Medicine Hospital of Southwest Medical University, Luzhou, Sichuan, China (mainland).

BACKGROUND With the complexity of calcaneal fracture (CF) increasing, its treatment has changed to include inserting the screw used to secure the facies articular posterior into the sustentaculum tail (ST). Some research progress has been made in this area, but there has been little in-depth research on the anatomical morphology of the sustentaculum tail, which is necessary for clinical surgery, and more information about Chinese anatomic characteristics and improved surgical techniques for CF are needed. MATERIAL AND METHODS This anatomical study, based on a three-dimensional (3D) computed tomographic (CT) reconstruction technique, included 287 dry calcaneus, consisting of 144 left and 143 right calcaneus.

Owing to its unique anatomical morphology and limited soft-tissue envelope, management of calcaneus fractures is a challenge to the orthopaedic surgeon, and surgical site infection (SSI) is one of the serious postoperative complications. In order to decrease the incidence of wound breakdown and improve clinical outcomes, it is necessary to understand which factors were associated with SSI. Read More

Advancing the deer calcaneus model for bone adaptation studies: ex vivo strains obtained after transecting the tension members suggest an unrecognized important role for shear strains.

J Anat 2018 Nov 8. Epub 2018 Nov 8.

Department of Orthopedics, University of Utah, Salt Lake City, UT, USA.

Sheep and deer calcanei are finding increased use as models for studies of bone adaptation, including advancing understanding of how the strain (deformation) environment influences the ontogenetic emergence of biomechanically relevant structural and material variations in cortical and trabecular bone. These artiodactyl calcanei seem ideal for these analyses because they function like simply loaded short-cantilevered beams with net compression and tension strains on the dorsal and plantar cortices, respectively. However, this habitual strain distribution requires more rigorous validation because it has been shown by limited in vivo and ex vivo strain measurements obtained during controlled ambulation (typically walking and trotting).

Assessment of Bony Subfibular Impingement in Flatfoot Patients Using Weight-Bearing CT Scans.

Foot Ankle Int 2018 Oct 8:1071100718804510. Epub 2018 Oct 8.

1 Institute for Foot and Ankle Reconstruction, Mercy Medical Center, Baltimore, MD, USA.

Background:: Lateral hindfoot pain in patients with flatfoot deformity is frequently attributed to subfibular impingement. It remains unclear whether this is primarily due to bony or soft-tissue impingement. No studies have used weight-bearing CT scans to evaluate subfibular impingement. Read More

Extended Sinus Tarsi Approach for Treatment of Displaced Intraarticular Calcaneal Fractures Compared to Extended Lateral Approach.

Foot Ankle Int 2018 Oct 5:1071100718803333. Epub 2018 Oct 5.

2 Department of Orthopedic Surgery, Regional Rheumatoid and Degenerative Arthritis Center, Chungnam National University Hospital, Daejeon, South Korea.

Background: We compared the radiographic results and clinical outcomes of patients operated on via the extended sinus tarsi approach (ESTA) and the extended lateral approach (ELA) for treatment of displaced intraarticular calcaneal fractures.

Methods: We retrospectively studied the utility of the ELA (46 patients, 52 feet) and the ESTA (56 patients, 64 feet) in patients operated on between January 2009 and March 2015. We evaluated pre- and postoperative x-rays and computed tomography (CT) data. Read More

Relationship between the Second to Fourth Finger Length Ratio and Calcaneus Quantitative Ultrasound.

Sci Rep 2018 Oct 2;8(1):14603. Epub 2018 Oct 2.

Faculty of Nursing, Baika Women's University, Ibaraki, Osaka, 567-8578, Japan.

This study aimed to characterize the relationship between the ratio of the length of the second and fourth fingers (2D:4D value) and the speed of sound of the calcaneus by quantitative ultrasound (QUS-SOS) in undergraduate female students. We recruited 138 young women with a mean age of 19.6 ± 1. Read More

On the sensitivity of quantitative susceptibility mapping for measuring trabecular bone density.

Magn Reson Med 2018 Sep 28. Epub 2018 Sep 28.

Department of Diagnostic and Interventional Radiology, Technical University of Munich, Munich, Germany.

Purpose: To develop a methodological framework to simultaneously measure and magnetic susceptibility in trabecularized yellow bone marrow and to investigate the sensitivity of Quantitative Susceptibility Mapping (QSM) for measuring trabecular bone density using a non-UTE multi-gradient echo sequence.

Methods: The ankle of 16 healthy volunteers and two patients was scanned using a time-interleaved multi-gradient-echo (TIMGRE) sequence. After field mapping based on water-fat separation methods and background field removal based on the Laplacian boundary value method, three different QSM dipole inversion schemes were implemented.

Department of Orthopaedic and Traumatology Cipto Mangunkusumo General Hospital, Faculty of Medicine Universitas Indonesia, Jakarta, Indonesia.

Introduction: In most cases, osteosarcoma occurs in the metaphysis of long bones such as femur, tibia, or humerus. Meanwhile, osteosarcoma of the talus is extremely rare.

Presentation Of Case: We presented a case of a thirty-eight-year-old male patient with osteosarcoma of the talus treatedwith limb salvage surgery. Read More
