PURPOSE To examine potential risk factors for the development of delayed or nonunion following elective ulnar shortening osteotomy using a dedicated osteotomy plating system. METHODS We performed a retrospective review of all patients who underwent elective ulnar shortening using the TriMed single osteotomy dynamic compression plating system by 1 of 2 fellowship-trained hand surgeons over a 5...

A retrospective observational study was performed to determine if early ambulation compromised healing in patients who underwent primary first metatarsophalangeal joint arthrodesis. The records of 42 patients undergoing 47 fusions were evaluated to determine time to radiographic union, time to clinical union, and return to regular shoes. Results showed that patients achieved clinical healing at...

An extension of the disjoint set union problem is considered, where the extra primitive backtrack(i) can undo the last i unions not yet undone. Let n be the total number of elements in all the sets. A data structure is presented that supports each union and find in O(lognj loglogn) worst-case time and each backtrack(i) in 0(1) worst-case time, irrespective of i. The total space required by the ...

The results and complications of 104 vascularised fibular grafts in 102 patients are presented. Bony union was ultimately achieved in 97 patients, with primary union in 84 (84%). The mean time to union was 15.5 weeks (8 to 40). In 13 patients, primary union was achieved at one end of the fibula and secondary union at the other end. In these patients, the mean time to union was 31.1 weeks (24 to...

BACKGROUND Low-intensity pulsed ultrasonography (LIPUS) is a form of mechanical stimulation that is delivered via a special device to the fracture site for the acceleration of fracture healing. We conducted a meta-analysis to assess the effect of LIPUS for fresh fractures in adults. METHODS MEDLINE, EMBASE and the Cochrane Library searched between Jan 1980 and Nov 2016. Studies should be quas...

The European Union has aspired to create an “ever closer union” among its people since the articulation of the European Union citizenship has been an important instrument towards it. However, attempts at creating this “ever closer union” have focused on homogenizing European citizens as a single entity without taking into account the heterogeneous differentials among such citizens. Gender diffe...

OBJECTIVES To measure the rate of union in patients with pseudoarthosis of the scaphoid, treated with trapezoidal bone grafting as outlined by Fernandez and 1 of 3 methods of internal fixation and to compare unions versus nonunions and potential predictors of union to determine if associations exist. DESIGN A retrospective radiologic study of scaphoid pseudoarthroses. SETTING Division of Or...

Aim of the present study was to compare the outcomes between exchanging reamed nailing (ERN) and augmentative compression plating (ACP) in treatment of femoral shaft nonunion after intra-medullary nailing (IMN) retrospectively. A retrospective, multicentre study was performed with 188 patients (190 cases)with femoral shaft nonunion after IMN, who received therapy with either ERN (n = 92) for 44...
