Risk Factors for Contralateral Tendon Rupture in Patients With Acute Achilles Tendon Rupture.

The present study was performed to determine the incidence and risk factors of contralateral Achilles tendon rupture after an initial tendon rupture, and to identify the associated patient characteristics. Medical records of 181 adult patients with acute Achilles tendon rupture were reviewed. We investigated the risk factors for contralateral Achilles tendon rupture and calculated the incidence density (per 100 person-years), survival rate, hazard ratios, and 95% confidence intervals.

Evaluation of the uninjured anterior talofibular ligament by ultrasound for assessing generalized joint hypermobility.

Background: Most clinicians use the Beighton score to assess generalized joint hypermobility (GJH) when deciding on the treatment of chronic lateral ankle instability (CLAI). The purpose of the study was to evaluate anterior talofibular ligament (ATFL) status by ultrasound and correlate these values with Beighton scores and the manual anterior drawer test (ADT).

Methods: The participants were divided into two groups, those without GJH (24 ankles) and with GJH (20 ankles).

Reliability of the EOS Imaging System for Assessment of the Spinal and Pelvic Alignment in the Sagittal Plane.

Background: The sagittal alignment of the spine and pelvis is not only closely related to the overall posture of the body but also to the evaluation and treatment of spine disease. In the last few years, the EOS imaging system, a new low-dose radiation X-ray device, became available for sagittal alignment assessment. However, there has been little research on the reliability of EOS.

The Treatment of Distal Radius Fractures with Ipsilateral Elbow Injury.

Background: The purpose of this study was to assess the functional outcomes of simultaneous distal radius fractures (DRFs) and ipsilateral elbow injuries (IEI) and to evaluate whether the DRFs and IEI affect each other's outcomes.

Methods: From February 2008 to March 2015, 29 of 846 patients treated for DRFs were found to be associated with IEI and 26 patients with follow-up over 12 months were enrolled. There were 12 men and 14 women with a mean age of 55 years (range, 17-86 years).

Atypical Fracture of the Proximal Shaft of the Ulna Associated with Prolonged Bisphosphonate Therapy.

Atypical fractures have been reported as a complication of long-standing bisphosphonate therapy and occur commonly in the subtrochanteric region or shaft of the femur showing typical radiographic features. We encountered a case of atypical fracture of the proximal one-third of the shaft of the ulna. Radiographic findings of this case differed from previously reported cases of ulnar fracture in terms of showing a transverse fracture line with cortical thickening and an oblique fracture line with anterior cortical spike.

Retrograde Intramedullary Nailing for Humerus Fracture in a Supine Position: Performing an Unfamiliar Procedure in a Familiar Position.

Intramedullary (IM) nailing for humeral shaft fracture has provided excellent outcomes in terms of fracture biology and cosmetic appearance because of the relatively small incision involved. However, antegrade nailing causes issues such as iatrogenic rotator cuff injury. Retrograde nail fixation method could avoid cuff injury, but has shortcomings such as the need for the prone or lateral decubitus position during surgery.

Radiologic Changes by Early Motion in Neck Fractures of the Fifth Metacarpal Treated with Antegrade Intramedullary Fixation.

Background: As intramedullary (IM) fixation is one of the fixation methods used in neck fractures of the fifth metacarpal, an early motion of injured finger can be allowed. The purpose of this study is to evaluate whether immediate active motion affects the stability of antegrade IM fixation in surgical treatment of neck fractures of the fifth metacarpal bone and to assess related factors.

Methods: Thirty one patients treated by closed reduction and antegrade IM fixation were consecutively enrolled.

New Technique for Removal of the Ulnar Intramedullary Nail Failed to Remove: Broken Assembly Piece in the Nail.

Methods about removal of intramedullary nail in complicated cases were reported in some literatures but there are no reports about nail removal in the ulna. The authors would like to report such a case and the technique. We removed bone of the inlet site and created another bony window using an osteotome to expose the interlocking screw holes.

Bilateral sternoclavicular joint dislocation due to sternal fracture: Is it a dislocation or a separation?

Traumatic bilateral sternoclavicular joint dislocation is very rare injury. In shoulder girdle injuries, anterior dislocation of the sternoclavicular joint accounts for 3 % and posterior sternoclavicular joint dislocation is lesser. Previous reported cases about bilateral sternoclavicular joint dislocation were result from proximal clavicle fracture with intact connection between sternum and ribs.

Shaft Fractures of Both Forearm Bones: The Outcomes of Surgical Treatment with Plating Only and Combined Plating and Intramedullary Nailing.

Background: Plate fixation is the most commonly used technique for the treatment of shaft fractures of both forearm bones (SFBFBs). However, all fractures are difficult to treat with plate fixation because of soft tissue injuries, fracture patterns, or the patient's condition. The purpose of this study is to compare the functional results of plate fixation only and combined plate and intramedullary (IM) nail fixation in SFBFBs.

Unstable Simple Elbow Dislocation Treated with the Repair of Lateral Collateral Ligament Complex.

Background: Unstable simple elbow dislocation (USED) repair is challenged by the maintenance of joint reduction; hence, primary repair or reconstruction of disrupted ligaments is required to maintain the congruency and allow early motion of the elbow. We evaluated the effectiveness and the outcome of lateral collateral ligament (LCL) complex repair with additional medial collateral ligament (MCL) repair in cases of USED.

Methods: We retrospectively reviewed 21 cases of diagnosed USED without fractures around the elbow that were treated with primary ligament repair.

Effect of zoledronate on the expression of vascular endothelial growth factor-a by articular chondrocytes and synovial cells: an in vitro study.

Background: The aim of this in vitro study was to determine the effect of zoledronate, which is frequently used to treat osteoporosis, on osteoarthritis by analyzing zoledronate-induced expression of vascular endothelial growth factor-A (VEGF-A) in chondrocytes and synovial cells.

Methods: After chondrocytes and synovial cells were separated and cultured, zoledronate was added, and VEGF-A and pigment epithelium-derived factor (PEDF) expression were quantified by real-time polymerase chain reaction and Western blotting.

Results: There was no significant difference in the expression of VEGF-A mRNA in chondrocytes between the zoledronate group and the control group on the 8th day of culture.

The large-conductance calcium-activated potassium channel holds the key to the conundrum of familial hypokalemic periodic paralysis.

Purpose: Familial hypokalemic periodic paralysis (HOKPP) is an autosomal dominant channelopathy characterized by episodic attacks of muscle weakness and hypokalemia. Mutations in the calcium channel gene, CACNA1S, or the sodium channel gene, SCN4A, have been found to be responsible for HOKPP; however, the mechanism that causes hypokalemia remains to be determined. The aim of this study was to improve the understanding of this mechanism by investigating the expression of calcium-activated potassium (KCa) channel genes in HOKPP patients.

Evaluation of associated carpal bone fractures in distal radial fractures.

Background: The purpose of this study was to investigate the frequency and distribution of associated carpal bone fractures (CBFs) in distal radial fractures (DRFs).

Methods: Three hundred and thirteen patients who underwent surgical treatment for DRFs between March 2007 and January 2010 were reviewed retrospectively. In this study, 223 patients who had preoperative computed tomography (CT) were included.

Evaluation of the sigmoid notch involvement in the intra-articular distal radius fractures: the efficacy of computed tomography compared with plain X-ray.

Background: The purpose of this study is to evaluate the efficacy of computed tomography (CT) scans compared with plain radiographs on detecting the involvement of the sigmoid notch.

Methods: This study involved 121 cases diagnosed as the intra-articular distal radius fracture and performed post-reduction CT scans. We determined the presence of the sigmoid notch involvement with both plain radiographs and CT scans and compared findings of plain radiographs with CT scans about the incidence and the pattern of injuries.

A clinical comparison of continuous interscalene brachial plexus block with different basal infusion rates of 0.2% ropivacaine for shoulder surgery.

Background: A continuous interscalene brachial plexus block is a highly effective postoperative analgesic modality after shoulder surgery. However, there is no consensus regarding the optimal basal infusion rate of ropivacaine for a continuous interscalene brachial plexus block. A prospective, double blind study was performed to compare two different basal rates of 0.

Background: This study evaluated the outcomes of debridement arthroplasty for stiff elbows, as well as the factors affecting clinical outcomes after surgical treatment.

Methods: Eighteen patients with post-traumatic stiff elbows were treated with debridement arthroplasty using a posterior approach. The mean patient age was 33 years (range, 16 to 59 years), and the average follow-up period was 59 months (range, 24 to 141 months).

Revision open Bankart surgery after arthroscopic repair for traumatic anterior shoulder instability.

Background: Only a few studies have provided homogeneous analysis of open revision surgery after a failed arthroscopic Bankart procedure.

Hypothesis: Open Bankart revision surgery will be effective in a failed arthroscopic anterior stabilization but inevitably results in a loss of range of motion, especially external rotation.

Study Design: Case series; Level of evidence, 4.
