An optimised method for quantifying glenoid orientation

A robust quantification method is essential for inter-subject glenoid comparison and planning of total shoulder arthroplasty. This study compared various scapular and glenoid axes with each other in order to optimally define the most appropriate method of quantifying glenoid version and inclination. Six glenoid and eight scapular axes were defined and quantified from identifiable landmarks of twenty-one scapular image scans. Pathology independency and insensitivity of each axis to inter-subject morphological variation within its region was tested. Glenoid version and inclination were calculated using the best axes from the two regions. The best glenoid axis was the normal to a least-square plane fit on the glenoid rim, directed approximately medio-laterally. The best scapular axis was the normal to a plane formed by the spine root and lateral border ridge. Glenoid inclination was 15.7° ± 5.1° superiorly and version was 4.9° ± 6.1°, retroversion. The choice of axes in the present technique makes it insensitive to pathology and scapular morphological variabilities. Its application would effectively improve inter-subject glenoid version comparison, surgical planning and design of prostheses for shoulder arthroplasty

Giant Cell Tumor along with Secondary Aneurysmal Bone Cyst of Scapula: a rare Presentation

Giant cell tumor (GCT) is a distinctive lesion characterized by the proliferation of multinucleate giant cells in a stroma of mononuclear cells; it is generally seen in skeletally mature individuals. GCT of bone is usually found in the long bones around the knee or in the distal radius of young adults and is unusual in the flat bones. We report a case of GCT of the acromion of the scapula; with a secondary aneurysmal bone cyst; in a 30-year-old female. Based on our review of the eng language medical literature; it appears that the occurrence of a GCT along with a secondary aneurysmal bone cyst in flat bones (e.g.. the scapula) is very rare

Nonunion of a Scapular Spine Fracture: Case Report and Management with Open Reduction; Internal fixation; and Bone Graft

Fractures of the scapular spine are relatively uncommon. We report a case of a 39 year old male who developed an atrophic non-union scapular spine fracture entering the spino-glenoid notch. We describe our experience with this rare fracture pattern and identify the need for early internal fixation in the young; active and working population
