Stand-Alone Cervical Cages in 2-Level Anterior Interbody Fusion in Cervical Spondylotic Myelopathy: Results from a Minimum 2-Year Follow-up.

Study Design: A retrospective review of patients who underwent 2-level anterior cervical discectomy and fusion (ACDF) with standalone polyetheretherketone (PEEK) cages for cervical spondylotic myelopathy (CSM).

Purpose: To evaluate the efficacy of stand-alone PEEK cage in 2-level cervical interbody fusion for CSM.

Overview Of Literature: ACDF is a standard surgical procedure to treat degenerative disc disease.

The Inaccuracy of Surface Landmarks for the Anterior Approach to the Cervical Spine in Southern Chinese Patients.

Study Design: Observational study.

Purpose: To assess the correlational accuracy between the traditional anatomic landmarks of the neck and their corresponding vertebral levels in Southern Chinese patients.

Overview Of Literature: Recent studies have demonstrated discrepancies between traditional anatomic landmarks of the neck and their corresponding cervical vertebra.

Quantitative Anatomy of C7 Vertebra in Southern Chinese for Insertion of Lateral Mass Screws and Pedicle Screws.

Study Design: Retrospective study.

Purpose: To analyze the quantitative anatomy of C7 vertebra for insertion of lateral mass screws and pedicle screws in Southern Chinese patients.

Overview Of Literature: C7 lateral mass is smaller when compared to other subaxial cervical levels, which limits the length of lateral mass screws that can be used.

Neighbourhood effects on body constitution-A case study of Hong Kong.

Traditional Chinese Medicine (TCM) has long perceived environment as an integral part of the development of body constitution, which is a personal state of health closely related to disease presence. Despite of the ever-growing studies on the clinical effectiveness of TCM and the scientific linking between body constitution and diseases, the geographical influence on body constitution has yet remained an unexplored territory. This study sought to investigate whether the neighbourhood environment is relevant to the composition of body type of a population through statistical multilevel and Geographic Information Systems modelling.

Single-door cervical laminoplasty using titanium miniplates alone.

Purpose: To review outcome of 29 patients who underwent single-door cervical laminoplasty for myelopathy using titanium miniplates alone.

Methods: Records of 20 men and 9 women aged 35 to 79 (mean, 64.3) years who underwent single-door cervical laminoplasty for myelopathy using titanium miniplates alone were reviewed.

Pulsed electromagnetic field therapy promotes healing and microcirculation of chronic diabetic foot ulcers: a pilot study.

Objective: To examine the effects of pulsed electromagnetic field (PEMF) therapy on promoting the healing and microcirculation of chronic diabetic foot ulcers.

Design: A randomized, double-blind, placebo-controlled clinical trial on a homogenous subset of chronic diabetic foot ulcers.

Setting: Hospital and university.

Femoral tunnel widening after quadrupled hamstring anterior cruciate ligament reconstruction.

Purpose: To evaluate the extent of femoral tunnel widening after quadrupled hamstring anterior cruciate ligament reconstruction using femoral cross pin fixation in contrast to bioabsorbable screw fixation augmented with Endopearl.

Methods: 16 patients underwent cross pin femoral fixation and the next 15 underwent bioabsorbable screw fixation augmented with Endopearl. The patients were evaluated radiographically for femoral tunnel widening.

A small-area study of environmental risk assessment of outdoor falls.

Falls in public places are an issue of great health concern especially for the elderly. Falls among the elderly is also a major health burden in many countries. This study describes a spatial approach to assess environmental causes of outdoor falls using a small urban community in Hong Kong as an example.

Anatomic variations of neurovascular structures of the ankle in relation to arthroscopic portals: a cadaveric study of Chinese subjects.

Purpose: To investigate anatomic variations of neurovascular structures in the ankle and the safety margin for arthroscopic portals.

Methods: 11 left and 12 right ankles from 8 female and 15 male fresh cadavers of Chinese ethnicity aged 53 to 88 (mean, 68) years were used. The ankle was standardised in a plantigrade position, zero-degree inversion, and neutral rotation.

Rotary subluxation of the metacarpophalangeal thumb joint: a case report.

Irreducible rotary subluxation of the metacarpophalangeal joint (MCPJ) of the thumb is a rare entity. Open reduction is indicated when signs of irreducibility are seen on the radiographs. We present one such case caused by displacement of the sesamoid bone into the intercondylar notch of the first metacarpal bone.

Anterior spinal fusion versus laminoplasty for cervical spondylotic myelopathy: a retrospective review.

Purpose: To compare outcomes of anterior spinal fusion (ASF) versus laminoplasty for cervical spondylotic myelopathy (CSM).

Methods: Records of 26 women and 37 men aged 34 to 83 (mean, 67) years who underwent ASF or laminoplasty for CSM were reviewed. Patient demographics, duration of symptoms, pre- and post-operative Japanese Orthopaedic Association (JOA) scores, Hirabayashi recovery rate, and radiographic features (including anteroposterior canal diameter, Pavlov ratio, and number of levels compressed) were compared.

An ecological study of physical environmental risk factors for elderly falls in an urban setting of Hong Kong.

Elderly fall has become an issue of great public health concern and typically important to the aging population in Hong Kong because it carries a great burden to the individuals and the society. More accurate information about environmental risk factors to falls among the elderly could alleviate if not overcome the situation. Conventional approaches to elderly falls were mainly conducted using statistical methods and clinical tests on falls.

Mycotic aortic aneurysm following treatment of pyogenic vertebral osteomyelitis.

Mycotic aortic aneurysm is a surgical emergency. However, its bizarre presentations could delay the golden hour of surgical reconstruction which is the mainstay of treatment. We report a case of mycotic aneurysm of the aortic arch which developed in the postoperative period after surgical treatment of pyogenic vertebral osteomyelitis at the lower thoracic level.
