Combination of percutaneous unilateral translaminar facet screw fixation and interbody fusion for treatment of lower lumbar vertebra diseases: a follow-up study.
To investigate the feasibility and efficacy of sight-guided percutaneous unilateral translaminar facet screw fixation (TLFSF) with interbody fusion for treatment of lower lumbar vertebra diseases. ⋯ Sight-guided percutaneous unilateral TLFSF with interbody fusion for treatment of lower lumbar disease is simple and minimally invasive, with good screw accuracy and security, high fusion rate, and good efficacy. However, specific surgical indications must be strictly followed.

Comparative StudyBiomechanical analysis of four types of internal fixation in subtrochanteric fracture models.
To compare the biomechanical properties of four types of internal fixation (proximal femoral nail [PFN], dynamic hip screw [DHS], dynamic condylar screw [DCS], and proximal femoral locking plate [PFLP]) for different types of subtrochanteric fractures. ⋯ Four types of internal fixation achieve better stabilities for type I subtrochanteric fractures. PFN and PFLP produce reliable stability in type IIIA subtrochanteric fractures. If the medial buttress is restored, DCS can be considered. For type IV subtrochanteric fractures, only PFN provides stable fixation. PFLP is suitable for comminuted fractures with large fragments.

Comparative StudyWhat is the rate of lumbar adjacent segment disease after percutaneous versus open fusion?
Adjacent segment disease (ASD) requiring treatment or re-operation is a common problem after surgery on the lumbar spine. The hypothesis of this retrospective study was that ASD occurs less often following lumbar spine fusion in patients who undergo percutaneous minimally invasive (MIS) instrumentation than in those in whom open instrumentation is used. ⋯ Contrary to our hypothesis, there was no significant difference in incidence of ASD in patients who had underwent open versus percutaneous instrumentation following anterior lumbar interbody fusion.
