Leech Therapy for the Treatment of Venous Congestion in Flaps, Digital Re-Plants and Revascularisations – A Two Year Review from a Regional Centre

Leeches are fresh water parasitic invertebrates that belong to the phylum Annelida. There are reports of leeches attaching to mucous membranes of the throat and extracting blood leading to swelling, suffocation, bleeding and death.

Biceps sheath fluid on shoulder ultrasound as a predictor of rotator cuff tear: analysis of a consecutive cohort

Ultrasound provides evaluation of a rotator cuff disease with accuracy comparable to that of magnetic resonance imaging.  Fluid in the sheath of the long head of the biceps tendon (LHB), identified on ultrasound scan, has been associated with disease of the rotator cuff, (LHB) and glenohumeral joint.

An overview of the regeneration of skeletal muscle

It has only recently been acknowledged widely that mature skeletal muscle has the ability to regenerate, although reports on this phenomenon have existed in the research literature some 40 years.

Experimental skeletal muscle grafts as a model of regeneration

Skeletal muscle cells regenerate rapidly in muscle grafts, arising from satellite cells in the surviving peripheral fibres of the graft within 2 days after grafting.  The resultant myoblasts progress towards the necrotic graft centre and occupy the area by 5 days.

The identification of myogenic cells in skeletal muscle, with emphasis on the use of tritiated thymidine autoradiography and desmin antibodies

The identification of myogenic precursor cells (mcp) is a key factor in determining the early events in the myogenesis and regeneration of skeletal muscle.  Although satellite cells have long been established as the providers of myoblastic cells, very little is really known (apart from their anatomical location in relation to muscle fibres and their ability to migrate) about the precise role of satellite cells in myogenesis.

Spinal cord infarction caused by malignant intramedullary glioma: the traps of epidemiology and travel history

A 19-year-old patient of Pakistani origin present with paraplegia and a sensory level at T4.  The patient was well until three weeks prior to his admission when he developed back and left leg pain.  One week later he developed paraparesis that over the next 10 days progress to paraplegia and loss of sphincter function.

Cord compression secondary to intradural ossification

The authors describe  two patient’s presenting with a previous history of spinal trauma and a several year history of sensory changes secondary to spinal cord compression. Both patient’s underwent laminectomy and spinal decompression operations. In both cases intradural bone causing neural compression was removed at operation.

Lateral medullary syndrome caused by penetrating head injury

Herein, we report a rare case of a patient surviving penetrating trauma to the brainstem.  Low velocity penetrating head injuries may be occult and are associated with a high incidence of vascular injury.

Combines fascia and mesh repair of incisional hernias

Incisional hernia is a relatively common complication following abdominal operations.  Due to high recurrence rates following primary suture, a prosthetic mesh is now usually used to repair the hernia.  Several different types of repair are described.

Laparoscopic subtotal cholecystectomy without cystic duct ligation

Cholecystectomy is made hazardous by distortion of the anatomy of Calot’s triangle by acute or chronic inflammation. Laparoscopic subtotal cholecystectomy (LSTC) without cystic duct ligation is an alternative to conversion to open surgery in difficult cases.

Rotator cuff repair in older patients

Increasingly, older patients expect a higher level of independence than people of previous generations.  Traditionally rotator cuff tears in patients over 65 years of age were thought to be unsuitable for surgical repair even through patients may have reduced shoulder function as a result.

Results of surface replacement proximal interphalangeal joint arthroplasty

To evaluate the clinical results and functional outcome measures of surface replacement proximal interphalangeal joint arthroplasty.  Proximal interphalangeal joint surface arthroplastiese perform by a single surgeon were retrospectively reviewed.

Do partial thickness, bursal side cuff tears affect outcome following arthroscopic subacromial decompression? A prospective comparative cohort study

The rotator cuff is a musculotendinuous unit essential for normal shoulder biomechanics with a mean tendon thickness of 10mm to 12mm.  It plays a major role in shoulder pathology with impingement pain and or rotator cuff tendon tears being some of the most common causes of pain and disability in the upper extremity.

Implant survivorship and clinical outcomes of the Bigliani-Flatow shoulder prosthesis at a mean of five years: A post-marketing surveillance study from three centres

This is the first study to report survivorship and clinical outcomes of a third generation shoulder prosthesis [Bigliani-Flatow (BF)], comparing BF total shoulder arthroplasty (TSA) versus hemiarthroplasty (HA); and cemented versus uncemented implantation.
