Reverse Geometry shoulder replacement requires fixation of a base plate (called a metaglene) to the glenoid to which a convex glenosphere is attached. Most systems use screws to achieve this fixation. The suprascapular nerve passes close to the glenoid and is known to be at risk of injury when devices and sutures are inserted into the glenoid. We investigate the risk posed to the suprascapular nerve by placement of metaglene fixation screws. Ten cadaveric shoulder specimens were used. A metaglene was inserted and fixed using 4 screws. The suprascapular nerve was dissected and its branches identified. The screw tips and their proximity to the nerve and branches were identified and recorded.Background
Materials and Methods
Surgical experience has been shown to improve the clinical outcomes in Total hip arthroplasty. The objective of this study was to compare clinical and radiological outcomes between Consultants and NCHDs grade surgeons for the Exeter total hip replacement taken from the Cappagh National Orthopaedic Hospital Joint Register. Between 2005 and 2008, 2749 primary total hip replacements were done, 433(15.78%) were Exeter total hip system. 380(86%) out of 433 were included in the study, 227(59%) were females and 154(41%) were males. A consultant was the primary surgeon for 193(51%) patients and an NCHD was the primary surgeon for 187(49%) patients. Mean age, at time of operation was 68 years. Clinical outcome was assessed with WOMAC and SF36 scoring system. Patients were invited to fill in the WOMAC and SF36 questionnaire, pre-operatively, at 6 months and at 2 years after the operation. Radiographs were evaluated for radiolucency with a standardized technique.Introduction
