This is a case series of 14 hamate body fractures, in the coronal plane, with 12 patients having an associated metacarpal injury. Treatment was either conservative or operative and was decided according to the degree of fracture displacement and presence of carpometacarpal subluxation. Patient follow-up was 14.8 months on average, using DASH scores and(More)
The diagnosis of osteoarthritis of the thumb carpometacarpal joint is made predominantly by correlating examination findings with patients' symptoms and radiographs. The importance of clinical examination is enhanced due to the poor correlation between radiological severity of osteoarthritis of this joint and symptoms. Despite the importance of clinical(More)
BACKGROUND Bibliometrics is the analysis of the content and citations of journal articles to quantify trends in published data. In this study, we aimed to use bibliometric analysis to identify the contribution of various countries to the plastic surgical literature over a 5-year period. METHODS In this study, the top 20 countries publishing articles on(More)
BACKGROUND Distinguishing necrotizing fasciitis from non-necrotizing soft-tissue infections remains a difficult clinical judgement call, with a paucity of diagnostic aids to the clinician. The aim of this study was to assess raised serum lactate as a point-of-care test to aid in differentiating necrotizing from non-necrotizing soft tissue infections. (More)
BACKGROUND Outcome measures are increasingly important in the modern National Health Service. In the care of children born with cleft lip and/or palate there are many different outcomes to consider but only a few reliable, validated outcome measures exist. The dmft (decayed, missing and filled teeth) index and cleft speech characteristics (CSCs) are used(More)
Deep prosthetic joint infection remains an uncommon but serious complication of total hip replacement. We reviewed 24 patients with recalcitrant hip wounds following infected total hip replacement treated with either pedicled rectus femoris or vastus lateralis muscle flaps between 1998 and 2009. The mean age of the patients was 67.4 years (42 to 86) with(More)
A retrospective analysis of 227 patients undergoing ultrasonography (US) of the hand/wrist over a three-year period in a district general hospital trust was performed. The usefulness in each case was assessed by two independent reviewers using a qualitative rating system, as (A) Useful: determines management, (B) Useful: contributory, (C) Not useful: not(More)
BACKGROUND Zone 1 flexor digitorum profundus injury often precludes the use of a simple core suture as a result of a distal remnant that is too short. The aim of this study was to assess the senior author's (S.I.) simple technique for reinsertion of the flexor digitorum profundus tendon. METHODS The case series consisted of 12 patients who required a(More)
PURPOSE To assess the reliability of the Eaton and Glickel classification for base of thumb osteoarthritis. METHODS The interrater and intrarater reliability of this classification were assessed by comparing ratings from 6 raters using quadratic weighted kappa scores. RESULTS Median inter-rater reliability ranged from kappa of .53 to .54; intrarater(More)
