PURPOSE: Gross hip instability is a rare complication after hip arthroscopy, and there is limited literature surrounding this topic. This systematic review investigates cases of gross hip instability after arthroscopy and discusses the risk factors associated with this complication. METHODS: A systematic search was performed in duplicate for studies investigating gross hip instability after hip arthroscopy up to October 2015.

The frequency of joint symptoms was determined amongst 2022 affluent and 2210 poor adults in Karachi, Pakistan. Joint pain was significantly (P = 0.025) more common amongst the affluent (6.6%) compared with the poor (5%) and this was due to a significantly greater frequency of knee pain in the richer community (3% vs 1.8%; P = 0.008). The prevalence increased with age and was more common in females. Almost half were associated with varus deformity, suggesting the presence of associated OA in a high proportion.

Two hundred and sixteen patients with non-insulin-dependent diabetes (NIDDM) and 216 age- and gender-matched controls were studied to assess the prevalence of limited joint mobility (LJM). Joint mobility was measured by goniometry at metacarpophalangeal and subtalar joints, and those in whom a prayer sign was elicited were said to have cheiroarthropathy. Forty diabetic patients and 10 controls had cheirorathropathy.

BACKGROUND: The quasistatic neutral zone is a surrogate for neutral region stiffness of spinal motion segments. No similar measure of dynamic stiffness has been validated. Because parameters related to stiffness are likely to be affected by loading rate and disc degeneration, we examined the effect of those factors on motion parameters derived from continuous motion data. METHODS: Fifteen human lumbar motion segments were tested with continuous flexion-extension pure moments at 0.5, 3.0 and 6.0 degrees /s.

BACKGROUND: Prolotherapy is an alternative therapy for chronic musculoskeletal injury including joint laxity. The commonly used injectant, D-glucose (dextrose), is hypothesized to improve ligament mechanics and decrease pain through an inflammatory mechanism. No study has investigated the mechanical effects of prolotherapy on stretch-injured ligaments. HYPOTHESES: Dextrose injections will enlarge cross-sectional area, decrease laxity, strengthen, and stiffen stretch-injured medial collateral ligaments (MCLs) compared with controls.

The problems of cervical spine osteochondrosis with hypermobility are of great medical and social significance. Physical rehabilitation methods can improve effectiveness of basic drug therapy. These include isometric exercises, postisometric muscle relaxation, proprioceptive neuromuscular facilitation, postural exercises and special massage.

QUESTION: What is the lifetime and current prevalence of thumb problems in Australian physiotherapists and what are the factors associated with thumb problems? DESIGN: Survey of a random cross-section of physiotherapists. PARTICIPANTS: 1562(approximately 10% of the total) registered Australian physiotherapists. OUTCOME MEASURES: General questions covered demographic information, area of practice, hours worked per week, and years worked as a physiotherapist.

Intervertebral dysfunction refers to a biomechanical fault which is abnormal in both its dynamic and static components. A subluxation may be considered as being fixated and also slightly malpositioned in one or more axes of rotation. Subluxation may be considered as one component of a complex or syndrome of intervertebral dyskinesia, dysarthrosis or dysfunction. The biochemical and histological components explain some of the pain mechanisms, tissue changes and residual effects of acute and chronic intervertebral fixation and the need for repeated spinal manipulations and prolonged care.

A case history demonstrating a cause-effect relationship between sacroiliac sprain and a 'snapping hip' is presented. Periodic iliac manipulation is shown to eliminate crepitus elicited by simultaneous active or passive extension of the knee and hip. The significance of this case history as evidence of the efficacy of iliac manipulation in the management of sacroiliac syndrome is discussed.

The purpose of this paper is to review the current information on atlantoaxial instability in Down's syndrome. There are potentially fatal consequences to performing adjustive manipulation to the cervical spine of the Down's patient. Atlantoaxial subluxation can cause death. Up to 50% of those suffering from atlantoaxial instability have it due to anomalous axis formation and/or agenesis or laxity of the transverse ligament. Trauma or progressive anterior displacement of atlas may cause serious neurological complications.
