Femoroacetabular Junction Impingement (FAI) describes abnormalities
in the shape of the femoral head–neck junction, or abnormalities
in the orientation of the acetabulum. In the short term, FAI can
give rise to pain and disability, and in the long-term it significantly increases
the risk of developing osteoarthritis. The Femoroacetabular Impingement
Trial (FAIT) aims to determine whether operative or non-operative
intervention is more effective at improving symptoms and preventing
the development and progression of osteoarthritis. FAIT is a multicentre superiority parallel two-arm randomised
controlled trial comparing physiotherapy and activity modification
with arthroscopic surgery for the treatment of symptomatic FAI.
Patients aged 18 to 60 with clinical and radiological evidence of
FAI are eligible. Principal exclusion criteria include previous
surgery to the index hip, established osteoarthritis (Kellgren–Lawrence
≥ 2), hip dysplasia (centre-edge angle <
20°), and completion
of a physiotherapy programme targeting FAI within the previous 12
months. Recruitment will take place over 24 months and 120 patients
will be randomised in a 1:1 ratio and followed up for three years.
The two primary outcome measures are change in hip outcome score
eight months post-randomisation (approximately six-months post-intervention
initiation) and change in radiographic minimum joint space width
38 months post-randomisation. ClinicalTrials.gov: NCT01893034. Cite this article: Aims
Methods
Treatment for osteoarthritis (OA) has traditionally
focused on joint replacement for end-stage disease. An increasing number
of surgical and pharmaceutical strategies for disease prevention
have now been proposed. However, these require the ability to identify
OA at a stage when it is potentially reversible, and detect small
changes in cartilage structure and function to enable treatment
efficacy to be evaluated within an acceptable timeframe. This has
not been possible using conventional imaging techniques but recent
advances in musculoskeletal imaging have been significant. In this
review we discuss the role of different imaging modalities in the
diagnosis of the earliest changes of OA. The increasing number of
MRI sequences that are able to non-invasively detect biochemical
changes in cartilage that precede structural damage may offer a
great advance in the diagnosis and treatment of this debilitating
condition. Cite this article:
The NHS will soon implement 18 week referral to treatment targets. A prospective study was performed whereby from 2004–6, referral letters from General Practitioners suggesting a diagnosis specifically of Morton’s neuroma, resulted in randomised assignment to either direct referral for USI or to the specialist Foot and Ankle outpatient clinic. Patients with less specific referral letters were evaluated in clinic and referred for USI as appropriate. A comparison was made of the sensitivity and specificity of the referral pathways, financial implications and the time to treatment (TTT).
Of 57 patients for whom the GP had diagnosed a MN, 40 (70%) had the diagnosis confirmed on USI (other diagnoses were: 7 NAD, 3 ganglions, 2 bursae, 2 degenerative change, 1 glomus tumour, 1 angioleiomyoma, 1 SOL); this was comparable to the overall number referred to radiology with a suspected MN (69%). In the directly referred group, the mean TTT was 115 days (95%CI = 89 – 141), compared to 241 days (95%CI = 223 – 259) for those patients who went via a Foot and Ankle clinic. P<
0.0001.
The mean wait of this group is within the 18 week government target without any changes to our current radiology protocols. Using this direct referral protocol we saved 29 outpatient appointments; if followed for all eligible patients we would have saved 57 outpatient appointments.
From a retrospective, cohort study of 205 patients diagnosed with full-thickness tears of the rotator cuff, we determined, using ultrasound, the prevalence of such tears in their 129 siblings. Using 150 spouses as controls, the relative risk of full-thickness tears in siblings The significantly increased risk for tears in siblings implies that genetic factors play a major role in the development of full-thickness tears of the rotator cuff.
We performed MRI on 13 infants after operative reduction for developmental dysplasia of the hip (DDH). Using an axial gradient-echo sequence, MRI accurately depicted the acetabular anatomy and confirmed adequate reduction in 12 patients. The one patient with redislocation after surgery was correctly identified. MRI can be carried out quickly, inexpensively and without risk of radiation and is the investigation of choice to confirm adequate reduction in DDH.
