Fixation of the axis may be necessary in cases of atlantoaxial instability, secondary to different causes, such as congenital, trauma, neoplasm or inflammatory diseases.1 Additionally, the axis may be included in the spinal instrumentation procedure requiring occipitocervical stabilization or even extension of the subaxial cervical spine surgeries.1 The classic fixation of the atlantoaxial regi...

Displaced tripod zygomaticomaxillary complex (ZMC) fractures are generally treated with open reduction and 3-point rigid internal fixation at the frontozygomatic suture, zygomaticomaxillary buttress, and inferior orbital rim. However, a clinical dilemma still exists in the postoperative morbidities such as ectropion of the lower eyelid and palpability of the Ti-plate at the inferior orbital rim...

One hundred and sixteen patients with 129 ununited fractures were treated either by rigid internal fixation and bone grafting or, in 14 tibial non-unions, by posterolateral bone grafting. In 37 actively infected cases this was combined with sequestrectomy and appropriate antibiotics. The final success rate was 98.4%. Technical errors or inadequate immobilisation after operation in patients with...

Abstract When a sternum prosthesis is implemented, it must allow the movement of rib cage. The designs that have been developed are completely rigid, this aspect can present discomfort when breathing, as well fixation problems between and bone tissue. aim work to develop flexible device allows cage during breathing. Compliant mechanism design was by using pseudo-rigid body model (PRBM) starting...

PURPOSE To evaluate the ratio of soft tissue to hard tissue in bilateral sagittal split setback osteotomy with rigid internal fixation or wire fixation. MATERIALS AND METHODS A literature search was performed using PubMed, Medline, CINAHL, Web of Science, the Cochrane Library, and Google Scholar Beta. From the original 766 articles identified, 8 articles were included. Two articles were prosp...

BACKGROUND To allow osseous integration to occur and thus provide long-term stability, initial glenoid baseplate fixation must be sufficiently rigid. A major contributing factor to initial rigid fixation is baseplate screw fixation. Current baseplate designs use a 4-screw fixation construct. However, recent literature suggests adequate fixation can be achieved with fewer than 4 screws. The purp...

BACKGROUND Anterior transarticular screw (ATS) fixation is a useful surgical option for atlantoaxial (AA) stabilization. This report presents a revised ATS method for AA fusion. METHODS A 79-year-old male presented with AA instability attributed both to an old odontoid fracture and severe degeneration of the lateral atlantoaxial joints (LAAJs). ATS fixation was performed through the conventio...

The evolution of occipitocervical fixation and new rigid universal screw-rod construct technology has allowed secure anchorage at each level of the occipitocervical junction with the elimination of rigid external orthoses. Rigid occipitocervical instrumentation constructs have achieved higher fusion rates and less postoperative immobilization-associated complications. Outcomes have improved com...

Reconstruction of the anterior cruciate ligament is a frequently performed procedure that has had outstanding results. Outcomes are dependent upon an early postoperative physical therapy program that stresses early motion. Early rehabilitation demands rigid intraoperative mechanical fixation of the graft since therapy begins before biologic incorporation of the graft in the bone tunnels. Regard...
