Revision of failed acetabular components utilizing a cementless oblong cup: an average 9-year follow-up study.
Failure of acetabular components often leads to bone loss with extensive elongated defects in the surrounding bone. In these cases, reconstruction is challenging and stable fixation of the revision implant difficult. The use of an oblong cup has been described as an option for acetabular reconstruction in such revisions. We report the first long-term results obtained with this implant to date. ⋯ This 12-year clinical study demonstrates that the LOR cup offers a successful concept for the revision of failed acetabular components that also promotes the biological reconstruction of bony defects. Compared with other methods with similarly long follow-ups, our long-term results prove this procedure has a very low rate of revision and aseptic implant failure.

Case ReportsOncogenic osteomalacia: two case reports with surprisingly different outcomes.
Oncogenic osteomalacia is a rare paraneoplastic syndrome of acquired hypophosphatemic osteomalacia, resulting from a deficit in renal tubular phosphate reabsorption, in which fibroblast growth factor 23 (FGF23) seems to be implicated. This condition is usually associated with a phosphaturic mesenchymal tumor of mixed connective tissue located in the bone or soft tissue. The clinical and the radiologic findings are the same as those seen in osteomalacia, and the biochemical features include renal phosphate loss, low serum phosphate and 1,25-(OH)(2) vitD(3) levels, increased alkaline phosphatase, and normal calcium, PTH, calcitonin, 25-OH-vitD(3) and 25,25-(OH)(2) vitD(3). ⋯ This disease usually remits with complete tumor resection. Nevertheless, if this is not possible, oral treatment with phosphate, calcium and calcitriol can improve the symptoms. If scintigraphy of the tumor shows octreotide receptors, patients may respond partially to therapy with somatostatin analogs, with stabilization of the lesion.

Case ReportsHip and knee dislocation during femoral lengthening in congenital short femur: a rare case report.
Congenital short femur is a rare and complex deformity that is often associated with other anomalies. There are few reports of either hip or knee dislocations during femoral lengthening in congenital short femur predisposed by associated anomaly. ⋯ We have this case of congenital short femur, where both hip and knee dislocation occurs during femoral lengthening. We reviewed different article to understand the cause and avoid such unwanted complications in future.

Case ReportsReconstruction of the articular surface of the humeral head after locked posterior shoulder dislocation: a case report.
Posterior dislocations of the glenohumeral joint are extremely rare (2-4% of all shoulder dislocations) and often associated with bone or ligamentary injuries. Though the reverse Hill-Sachs lesion is a common injury associated with posterior shoulder dislocation, there have been only few articles describing specific treatments for this type of humeral head defect. ⋯ The patient was doing quite well with no complaints, good range of shoulder motion and no recurrence of posterior shoulder dislocation despite several epileptic seizures, 1.5 years after surgical reconstruction of the anatomy of the humeral head. His right shoulder function revealed to be "excellent" or "good", assessed with an absolute Constant Score of 76 points and a relative Score of 88% when compared with an age- and sex-matched normal population.
