Relationship between gait parameter and spinal sagittal profiles in asymptomatic subjects.

Background: To study the gait parameters in asymptomatic volunteers and investigate the correlation between the gait and several radiographic sagittal profiles.

Methods: Asymptomatic volunteers (20-50 years of age) were included and allocated into three subgroups depending on pelvic incidence (low, normal, and high). Standing whole spine radiographs and gait analysis data were obtained.

Scapular dyskinesis after treatment of proximal humerus fracture, a 3-dimensional motion analysis and clinical outcomes.

Background: The alteration of scapular kinematics can predispose patients to shoulder pathologies and dysfunction. Previous literature has associated various types of shoulder injuries with scapular dyskinesis, but there are limited studies regarding the effect that proximal humeral fractures (PHFs) have on scapular dyskinesis. This study aims to determine the change in scapulohumeral rhythm following treatment of a proximal humerus fracture as well as differences in shoulder motion and functional outcomes among patients who presented with or without scapular dyskinesis.

Cutoff Value for the Patient Acceptable Symptom State of the Thai IKDC Subjective Knee Form in Patients After Primary ACL Reconstruction.

Background: The Patient Acceptable Symptom State (PASS) cutoff is the value on a patient-reported outcome measure beyond which patients consider themselves to be "feeling well." There are limited data regarding the PASS threshold for non-English versions of the International Knee Documentation Committee-Subjective Knee Form (IKDC-SKF).

Purpose: To establish the PASS cutoff for the Thai version of the IKDC-SKF for patients undergoing primary anterior cruciate ligament reconstruction (ACLR) and to identify factors to achieve PASS after surgery.

A new classification for combined greater tuberosity fracture and anterior shoulder dislocation: A study of fracture configurations and displacement after reduction.

Objective: The aim of this study was to propose a new classification of combined greater tuberosity (GT) fractures and anterior shoulder dislocation and studied the degree of displacement, functional outcomes, and need for additional surgery after reduction.

Methods: A cross-sectional study was conducted. We evaluated radiographs of patients treated for combined GT fractures and anterior shoulder dislocation.

Three-dimensional motion analysis of ten common Asian sitting positions in daily living and factors affect range of hip motions.

Background: Sitting involves many activities of daily life and requires most motion in the hip joint. Asians have more hip flexion and external rotation motions than Westerners owing to cultural and lifestyle differences. Being aware of the normal range of hip motion is essential in clinical practice.

Validity and reliability of smartphone applications for measurement of hip rotation, compared with three-dimensional motion analysis.

Background: Measurement of hip rotation is a crucial clinical parameter for the identification of hip problems and the monitoring of symptoms. The objective of this study was to determine whether the use of two smartphone applications is valid and reliable for the measurement of hip rotation.

Methods: An experimental, cross-sectional study was undertaken to assess passive hip internal and external rotation in three positions by two examiners.

Arthroscopic Treatment of a Large Mass of the Medial Side of the Leg Caused by Distal Extension of a Meniscal Cyst: A Case Report.

Case: We report a 39-year-old man who presented with a painful mass that had been growing over the anteromedial aspect of his left leg for 2 years and was recurrent after an open excisional biopsy. Magnetic resonance imaging showed a lobulated cyst that extended from the medial meniscus. Arthroscopic cyst decompression, anterior cruciate ligament reconstruction, partial meniscectomy, and repair of the meniscotibial capsule were performed.

Quantifying anterior knee pain during specific activities after using the bone-patellar tendon-bone graft for arthroscopic anterior cruciate ligament reconstruction.

Background/objective: There has been much debate about the optimal graft choice for an anterior cruciate ligament (ACL) reconstruction. Anterior knee pain is a common donor site problem when using a bone-patellar tendon-bone (BPTB) graft. However, knowledge of the characteristics of anterior knee pain during different daily activities is still limited.

A pilot study comparing the efficacy of two formulations of botulinum toxin type A for muscular calves contouring.

Background: Enlarged, hypertrophy calf muscles are common in Asian women and can cause psychological burden. Botulinum toxin A (BTA) has been widely used in treating masseteric muscle hypertrophy and it's efficacious as a noninvasive method for calf-contouring has been reported. Food and Drug Administration has approved onabotulinumtoxin A (ONA, Botox; Allergan Inc, Irvine, CA, USA) for upper face rejuvenation and it has off-label uses for calf-contouring.

Evaluation of the Effectiveness of Preoperative Blood Ordering Guideline in Elective Spine, Knee Replacement, and Hip Replacement Surgery.

Background: Preoperative blood ordering is necessary in most of the major orthopedic operations. However, over-crossmatching 200 units/day results in technician workload and compromises blood stock for other patients at Siriraj Hospital.

Objective: To evaluate the effectiveness of a new blood ordering guideline in spine and arthroplasty surgery at Siriraj Hospital by comparing the quantity of blood ordering between pre-guideline and guideline groups.

The anatomical safe zone for medial opening oblique wedge high tibial osteotomy.

Introduction: The end of medial opening oblique wedge high tibial osteotomy (HTO) points into a narrow area between the articular cartilage of the posterolateral proximal tibia and proximal tibiofibular joint (PTFJ) at the tibial site, which is an anatomical safe zone (ASZ) for osteotomy. We studied the ASZ and its relation to the fibular tip, including the level of posterior cruciate ligament (PCL) insertion, to avoid penetration into the knee and PTFJ, and PCL injury by osteotomy.

Methods: Ten pairs of embalmed cadaveric legs were disarticulated at the knee joint and then examined.

Single-bundle versus double-bundle anterior cruciate ligament reconstruction: a meta-analysis.

Objective: This meta-analysis study compares the treatment outcomes between single bundle (SB) and double bundle (DB) anterior cruciate ligament reconstructions (ACLR) including manual laxity tests, KT-1000 measurements and functional knee scores including International Knee Documentation Committee (IKDC) and Lysholm scores.

Data Sources: Medline, Scopus, Web of Science and Cochrane Central Register of Controlled Trials (January 1985 to March 2008).

Material And Method: All randomized controlled trials reporting one or more outcomes related to single bundle versus double bundle ACLR were recruited in the present study.

Radiographic assessment of the safe zone for medial oblique opening wedge high tibial osteotomy.

Purpose: To compare different cephalocaudal angles of the X-ray beam in measuring internal rotation of the proximal tibia that best demonstrates the safe zone.

Methods: 10 pairs of embalmed, disarticulated knee joints from 10 cadavers were used. Soft tissues around the proximal tibia and the proximal tibiofibular joint (PTFJ) were dissected to reveal the articular cartilage.

A spectral analysis of rotator cuff musculature electromyographic activity: surface and indwelling.

Electromyography (EMG) of the shoulder girdle is commonly performed; however, EMG spectral properties of shoulder muscles have not been clearly defined. The purpose of this study was to determine the maximum power frequency, Nyquist rate, and minimum sampling rate for indwelling and surface EMG of the normal shoulder girdle musculature. EMG signals were recorded using indwelling electrodes for the rotator cuff muscles and surface electrodes for ten additional shoulder muscles in ten healthy volunteers.

Primary anterior cruciate ligament reconstruction using contralateral patellar tendon autograft.

Primary ACL reconstruction using a contralateral patellar tendon autograft is an effective means of achieving symmetrical range of motion and strength after surgery. When the graft is harvested from the ipsilateral knee, the rehabilitation for the ACL graft and for the graft-donor site are different and have opposing goals. Rehabilitation for the ACL graft involves obtaining full range of motion, reducing swelling, and providing the appropriate stress to achieve graft maturation.
