Clinical outcomes after arthroscopic acetabular labral repair using knot-tying or knotless suture technique.

Background: The purpose of the study was to compare the clinical results of arthroscopic labral repair using knot-tying and knotless suture anchor techniques for patients with labral tears.

Methods: From September 2012 to May 2013, we performed a randomized, prospective analysis of 40 hips with labral tears treated with arthroscopic labral repair via knot-tying (group A) or knotless suture anchors (group B). A total of 33 patients were treated for labral tears, and 7 of them received bilateral labral repair.

Arthroscopic Treatment of Symptomatic Internal Snapping Hip with Combined Pathologies.

Background: Arthroscopic iliopsoas tendon release was introduced in 2000. The purpose of this study was to evaluate clinical outcomes of arthroscopic iliopsoas tendon release for painful internal snapping hip with concomitant hip pathologies.

Methods: Between January 2009 and December 2011, we performed arthroscopic iliopsoas tendon release and related surgeries in 25 patients (20 men and 5 women; mean age, 32 years; range, 17 to 53 years) with combined intraarticular hip pathologies.

Undertreatment of osteoporosis following hip fractures in jeju cohort study.

Background: Osteoporosis treatment following hip fracture is well known to not enough. We previously performed intervention study for orthopaedic surgeon's education and reported twofold increase in osteoporosis detection and treatment rate observed between 2005 and 2007. This follow-up observational study was conducted to find out the rate in which a diagnostic workup and treatment for osteoporosis were done in patients with hip fracture.

An improved technique for removing intramedullary antibiotic beads in osteomyelitis of the tibial shaft.

Background: The intramedullary insertion of antibiotic-impregnated cement beads is used widely for the treatment of intramedullary infection. This report describes an improved technique for removing chains of antibiotic beads inserted into the intramedullary cavity.

Methods: We examined four cases in three patients of the intramedullary insertion of chains of antibiotic-impregnated cement beads for the treatment of osteomyelitis of the diaphysis of the tibia after the fixation of fractures with interlocking nails.

First case report of an intracortical lipoma in an adult tibia.

The current case report describes an adult male with an intracortical lipoma accompanied by cystic changes in the tibial diaphysis. To the best of our knowledge, intracortical lipoma in an adult tibia has not been previously described. An anteroposterior radiograph of the tibia revealed an osteolytic lesion on the diaphysis.

Valeriana officinalis extract and its main component, valerenic acid, ameliorate D-galactose-induced reductions in memory, cell proliferation, and neuroblast differentiation by reducing corticosterone levels and lipid peroxidation.

Valeriana officinalis is used in herbal medicine of many cultures as mild sedatives and tranquilizers. In this study, we investigated the effects of extract from valerian root extracts and its major component, valerenic acid on memory function, cell proliferation, neuroblast differentiation, serum corticosterone, and lipid peroxidation in adult and aged mice. For the aging model, D-galactose (100 mg/kg) was administered subcutaneously to 6-week-old male mice for 10 weeks.

Is It a Simple Stress Fracture or Bisphosphonate-related Atypical Fracture?

A number of reports regarding atypical fractures of the femur have raised questions concerning the possible correlation between long-term bisphosphonate treatment and the occurrence of insufficiency fractures in the proximal femur. However, clinically, it is often confused whether is it a fatigue fracture because of implant induced stress concentration or a bisphosphonate-related atypical fracture, especially in a patient with a subtrochanteric fracture who receive bisphosphonate therapy after open reduction and internal fixation, such as dynamic hip screw (DHS) fixation for previous ipsilateral femoral neck or intertrochanteric fracture. The authors experienced a case of a progressive femoral insufficiency fracture in a woman who had been on Fosamax (Alendronic acid with Vitamin D; Merck & Co.

How isometric are the anatomic femoral tunnel and the anterior tibial tunnel for anterior cruciate ligament reconstruction?

Purpose: The purpose of this study was to evaluate the isometry of an anatomic femoral tunnel and anterior tibial tunnel positions.

Methods: Tibial tunnels were made at 2 different locations in 10 cadaveric knees: the conventional tunnel and a more anterior position. Three-dimensional computed tomography (CT) scanning was then performed at 0°, 30°, 60°, 90°, and 120°.

Longitudinal tear of the medial meniscus posterior horn in the anterior cruciate ligament-deficient knee significantly influences anterior stability.

Background: Longitudinal tears of the medial meniscus posterior horn (MMPH) are commonly associated with a chronic anterior cruciate ligament (ACL) deficiency. Many studies have demonstrated the importance of the medial meniscus in terms of limiting the amount of anterior-posterior tibial translation in response to anterior tibial loads in ACL-deficient knees.

Hypothesis: An MMPH tear in an ACL-deficient knee increases the anterior-posterior tibial translation and rotatory instability.

A case report of coronal fractures through the hamate, the capitate, and the trapezoid.

To our knowledge, the simultaneous coronal fractures of the hamate, capitate, and trapezoid have not been previously reported in the literature. There were few reports about coronal fractures of the hamate caused only by axial loading to the ulnar column. We report 43-year-old man who presented with painful swelling on the dorso-ulnar side of the wrist after striking a wall with his right clenched fist.

Transradioulnar single Kirschner-wire fixation versus conventional Kirschner-wire fixation for unstable fractures of both of the distal forearm bones in children.

The purpose of this study was to introduce transradioulnar single Kirschner-wire (K-wire) fixation technique for unstable fractures of both of the distal forearm bones in children and to evaluate the differences in clinical and radiographic results of osteosynthesis between this method and conventional K-wire fixation. Forty-one patients (20 conventional K-wire fixation, 21 transradioulnar single K-wire fixation) were reviewed who underwent a closed or mini-open reduction with K-wire fixation for fractures of both of the distal forearm bones. Their mean age at operation was 10.
