A 3D-printed load sharing implant achieved union of a 9-cm femoral segmental bone defect within three months using a hybrid Masquelet induction membrane technique. A case-report.

Case: A 30-year-old male was admitted in our hospital having an open left distal femoral fracture with 9-cm segmental bone defect and a closed proximal left tibial fracture. He was treated successfully using a Hybrid (Titanium Cage and Bone Graft) Masquelet Induction Membrane Technique (MIMT). His femoral fracture united 3-months post - operatively. The left tibia was treated initially with two locking plates. Following infection, a 3-cm tibial bone gap was treated with external fixation and conventional MIMT. The tibial fracture united 12-months post- operatively. Conclusion: The Hybrid MIMT achieved a successful healing outcome in this challenging case.

Does intraprostatic inflammation have a role in the pathogenesis and progression of benign prostatic hyperplasia?

OBJECTIVE: To compare the incidence of acute and/or chronic intraprostatic inflammation (ACI) in men undergoing transurethral resection of the prostate (TURP) for urinary retention and lower urinary tract symptoms (LUTS), as recently a role was suggested for ACI in the pathogenesis and progression of BPH, and urinary retention is considered an endpoint in the natural history of this condition. PATIENTS AND METHODS: Details of TURPs done between January 2003 and December 2005 at one institution were obtained from the operating theatre database. Patients were divided by indication (retention/LUTS). Clinical data and histology reports were then reviewed and bivariate and logistic regression used to compare the pathological features between these groups. RESULTS: Of 406 patients, 374 had evaluable data; 70% of men with urinary retention had ACI, vs 45% of those with LUTS (P < 0.001). On logistic regression, the pathological factors associated with TURP for acute retention compared to that for LUTS were ACI, old age, and resection weight to a lesser degree. CONCLUSION: Inflammation appears to be important in the pathogenesis and progression of BPH. In this study, the risk of urinary retention due to BPH was significantly greater in men with ACI than in those without, and the association of TURP for retention with ACI was stronger than that with prostate weight. This finding might offer new avenues for the medical treatment of men with LUTS due to BPH.
