BACKGROUND: The purpose of this study is to evaluate the functional outcome, union and complication rates after surgical treatment of unstable or displaced proximal humeral fractures using the Polarus intramedullary nail, by reviewing our institutional experience and the relevant current literature.

METHODS: Twenty-seven patients were treated operatively for proximal humeral fracture using the Polarus nail. Fractures were classified according to Neer's classification. A number of ...

Chronic tendon lesions are degenerative conditions and may represent a failure to repair or remodel the extracellular matrix after repeated micro-injury. Since TGF-beta is strongly associated with tissue repair, we investigated the expression of TGF-beta isoforms (beta1, beta2 and beta3) and their 2 signalling receptors (TGF-betaRI and TGF-betaRII) in normal and pathological Achilles tendons. In all tissues, all 3 TGF-beta isoforms and the 2 receptors were present at sites of blood ...

Atlas cDNA cell interaction arrays (CLONTECH) were used to examine degenerate tissue from four patients with Achilles tendon disorders, in order to identify changes in expression of genes important in cell-cell and cell-matrix interactions. The greatest difference between normal (post-mortem) and degenerate tissue samples was in the level of MMP-3 (stromelysin) mRNA, which was down-regulated in all the degenerate samples. Quantitative RT-PCR assay of RNA extracted from paired 'normal' ...

BACKGROUND: sports hernia is a well-recognized cause of groin pain in athletes involved in sports, especially football and rugby. Loss of range of motion of the hip joint is a possible contributory factor to stress across the symphysis pubis leading to the instability.

METHODS: twenty-five athletes presenting with sports hernia were matched to age, sex, physical/sports activity and co-morbidities with twenty-five athletes without sports hernia. The range of movement of both the hips was ...

The ulnar coronoid process plays a central role in elbow stability due to its unique anatomic characteristics. A fracture of the coronoid, although uncommon, represents a serious injury that can adversely affect functional outcome if not treated appropriately. Several surgical interventions addressing different fracture patterns are being increasingly recognised as effective treatment options even for smaller fragments. A review of the literature was performed in order to evaluate ...

The shoulder is the most frequently dislocated joint in the human body, anterior dislocation being the most common variant. For stability, the glenohumeral joint relies on both static and dynamic restraints and dislocation often results in damage to these restraints. For example, antero-inferior capsulolabral complex damage often occurs as a result of anterior dislocations (a ‘Bankart lesion’) and impaction of the dislocated humeral head against the rim of the antero-inferior glenoid can ...

BACKGROUND: The aim of this study was to explore the feasibility of using a non-absorbable biocompatible polyester patch to augment open repair of massive rotator cuff tears (Patch group) and compare outcomes with other treatment options (Non-patch group).

METHODS: Participants referred to orthopaedic clinics for rotator cuff surgery were recruited. Choice of intervention (Patch or Non-patch) was based on patient preference and intra-operative findings. Oxford Shoulder Score (OSS), ...

Groin pain has a wide differential diagnosis, and its aetiology may be multifactorial. Common causes include hip joint pathology, sports hernia and snapping psoas, but rarer causes such as stress fracture, spinal pathology and intra-pelvic causes must be considered. Investigation is specific to the diagnosis postulated through a carefully taken history and examination. Femoroacetabular impingement is common and increasingly managed with hip arthroscopy, good short term results being reported.
