RESUMEN
PURPOSE: The objective of this study is to evaluate the clinical and radiological results of reverse shoulder arthroplasty (RSA) with glenoid plating in a consecutive series of patients affected by cuff tear glenohumeral arthropathy with glenoid retroversion >15°. We hypothesized that autologous humeral head graft may be better stabilized between the baseplate and the native glenoid surface with the use of a glenoid plate. METHODS: Twenty consecutive patients affected by cuff tear arthropathy with glenoid retroversion >15° (B2 or C according to Walch classification) were enrolled in this study. To reconstruct the glenoid, a dedicated plate was used in addition to the standard reverse shoulder baseplate and the glenosphere. Clinical and radiological assessment was performed using constant score (CS), subjective shoulder value (SSV), X-rays and CT scan at 6, 12 and 24 months of follow-up. Healing and resorption of the graft and detection of the glenoid version were assessed. RESULTS: Sixteen patients were available for final follow-up. The mean preoperative retroversion of the glenoid was 24°, while the post-op was 2° (p = 0.002). At 24 months of follow-up, mean CS and SSV were 61 and 70. Respect to preoperative scores, the results were statistically significant (p < 0.001). The last CT scan revealed: a complete healing of the graft in 100% of cases; graft resorption less than 25% in two patients (12.5%); glenoid retroversion of 4°. A negative statistically significant correlation was found between final CS and preoperative glenoid retroversion (0.039). CONCLUSIONS: The present study reports the favorable outcomes of retroverted glenoid reconstruction with glenoid plates in RSA, an alternative method to address severe glenoid deficiency. LEVEL OF EVIDENCE: Level IV, case series with no comparison group.

OBJECTIVE: The osteochondromas represents is the most frequent benign lesion interesting the bone tissue. This lesion, often asymptomatic, can arise through mechanical, irritative or painful syndromes: "strategic exostosis". MATERIALS AND METHODS: In our present study we retrospectively evaluated 65 Caucasian patients, which have been treated surgically for symptomatic solitary exostosis from March 2004 to Jan 2011. The most frequent symptom referred by patient has been represented by pain. The others complains were related to nervous compression, esthetic injury and a reduction of range of motion. By using the VAS score we evaluated the post-operative bone pain at 3, 12 and 24 months. At the end of follow up we evaluated by a validated questionnaire the grade of patient satisfaction. RESULTS: No major surgical complication were found. The rate of disease recidivism was null. Only a small group of patient referred a persisting pain in the lesion area during the two years follow up. In this subgroup the rate of satisfaction was obviously reduced. CONCLUSIONS: In our opinion the surgical treatment of strategic exostosis, is safe and it should be recommended, since it allows to eliminate the noise with a low incidence of complications. The large majority of out patients were satisfied of the clinical improvement they experienced.
