Combined radial wedge and shortening osteotomy versus scaphocapitate arthrodesis in advanced Kienböck's disease.

Although various surgical techniques have been reported for the treatment of advanced Kienböck's disease (Lichtman stage IIIB and above), the ap- propriate operative treatment is still being debated. This study compared the clinical and radiological outcomes of combined radial wedge and shortening osteotomy (CRWSO) and scaphocapitate arthrodesis (SCA) in the treatment of advanced Kienböck's disease (above type IIIB) with a minimum of 3 years of follow-up. We analyzed the data from 16 and 13 patients who underwent CRWSO and SCA, respectively.

A novel technique of pulley creation for additional sagittal band reconstruction.

Because surgical treatment of chronic extensor tendon dislocation with sagittal band injury is complex and often requires donor grafts, we suggest a new technique: pulley creation for additional sagittal band reconstruction. A 76-year-old man diagnosed with chronic extensor tendon dislocation with radial sagittal band injury was treated by resecting the distended portion of the radial sagittal band, followed by plication. Using the remnant tissue obtained after resection, additional sagittal band reconstruction was performed using two mini soft suture anchors in the form of a pulley surrounding the extensor tendon.

Sequential Bilateral Hip Fractures in Elderly Patients.

Purpose: To evaluate the incidence and presentation of osteoporotic sequential bilateral hip fractures (SBHF) in Center for Joint Disease, Chonnam National University Hwasun Hospital as there are limited studies with variable results reported in Korea.

Materials And Methods: Records of 507 patients aged >60 years old presenting with osteoporotic hip fractures between 2009 and 2015 were retrospectively reviewed to document the occurrence and presentation of sequential hip fractures; mean post-treatment follow-up was 48 months. Additionally, any correlations between sequential fractures and initial fracture and risk factors were assessed.

Three-dimensional-printing Technology in Hip and Pelvic Surgery: Current Landscape.

The use of three-dimensional (3D) printing is becoming more common, including in the field of orthopaedic surgery. There are currently four primary clinical applications for 3D-printing in hip and pelvic surgeries: (i) 3D-printed anatomical models for planning and surgery simulation, (ii) patient-specific instruments (PSI), (iii) generation of prostheses with 3D-additive manufacturing, and (iv) custom 3D-printed prostheses. Simulation surgery using a 3D-printed bone model allows surgeons to develop better surgical approaches, test the feasibility of procedures and determine optimal location and size for a prosthesis.

Comparison of Radiological Parameters between Normal and Patellar Dislocation Groups in Korean Population: A Rotational Profile CT-Based Study.

Purpose: Patellofemoral instability is a common cause of anterior knee pain in adolescents and young adults. Most normal and pathological values for diagnosing patellofemoral instability are based on Western literature. We conducted this radiological study to determine normal values for different patellofemoral parameters in a Korean population and to evaluate their usefulness in diagnosis.

Surgical Treatment of Neglected Traumatic Quadriceps Tendon Rupture with Knee Ankylosis.

Quadriceps tendon rupture is an uncommon injury. This disabling condition is the result of direct or indirect trauma. It requires surgical repair to avoid poor outcomes in cases of neglected or chronic rupture.

Change in incidence of hip fracture in Gwangju City and Jeonnam Province, Korea, over 20 years.

Unlabelled: This study determined the incidence of hip fractures in Gwangju city and Jeonnam province of Korea in 2011 and compared it with the rates in the same area in 1991 and 2001.

Introduction: This study determined the incidence of hip fracture in Gwangju city and Jeonnam province in Korea in 2011 and compared it with the rates in the same area in 1991 and 2001, with the aim of identifying any changes in 2011.

Methods: Korea Health Insurance Review Agency patient data from Gwangju city and Jeonnam province for the period 2011 January 1 to December 31 was analyzed.

Progression of osteoarthritis after double- and single-bundle anterior cruciate ligament reconstruction.

Background: No consensus has been reached on the advantages of double-bundle (DB) anterior cruciate ligament reconstruction (ACLR) over the single-bundle (SB) technique, particularly with respect to the prevention of osteoarthritis (OA) after ACLR.

Purpose: To evaluate whether DB ACLR has any advantages in the prevention of OA or provides better stability and function after ACLR compared with the SB technique.

Study Design: Randomized controlled trial; Level of evidence, 2.

Vitrification of immature bovine oocytes by the microdrop method.

This study was conducted to determine the optimal vitrification conditions for immature bovine oocytes using the microdrop method. In experiment 1, the optimal pre-equilibration period for microdrop vitrification was examined. The maturation rate of vitrified oocytes with a 3 min first pre-equilibration period (41.
