Comparative StudyReducing the rate of early primary hip dislocation by combining a change in surgical technique and an increase in femoral head diameter to 36 mm.
We report how changes to our total hip arthroplasty (THA) surgical practise lead to a decrease in early hip dislocation rates. ⋯ We suggest that when primary hip arthroplasty is performed through a posterior approach, a low early dislocation rate can be achieved using the described methods.

Endoscopic bursectomy for the treatment of septic pre-patellar bursitis: a case series.
Operative treatment for septic pre-patellar bursitis generally involves open debridement in addition to an extended course of intravenous antibiotics. Skin necrosis and wound breakdown are potential complications of this procedure in addition to scar sensitivity and a prolonged recovery. ⋯ We conclude that endoscopic bursectomy is a safe and effective treatment for septic pre-patellar bursitis with a shortened hospital stay and a quicker return to work than conventional open debridement.

Cervical lateral mass screw fixation without fluoroscopic control: analysis of risk factors for complications associated with screw insertion.
To examine the outcome of cervical lateral mass screw fixation focusing on analysis of the risk factors for screw-related complications. ⋯ In the analysis of potential risk factors for violation of the VA foramen as well as FV during screw insertion, the former incidence was significantly related to the screw trajectory angle (lack of lateral angulation) in the axial plane, while the latter incidence was related to a poor screw trajectory angle in the sagittal plane.

Comparative StudySequencing-based detection of drug-resistant Mycobacterium tuberculosis in patients with spinal tuberculosis.
Traditionally, bacterial cultures serve as the gold standard for the detection of drug resistance and can provide evidence for directing the treatment of tuberculosis. However, this method has a low positive rate and is time consuming, which significantly limits its wide application. Thus, in the present study, the genes associated with drug resistance were amplified and sequenced to determine the presence of drug-resistant mutations in Mycobacterium tuberculosis. In addition, to find a more sensitive, specific, rapid, and simple method for the detection of drug-resistant bacteria, this method was compared with traditional bacterial culture. ⋯ These results indicated that PCR and DNA sequencing are rapid, sensitive, and specific methods for the detection of drug-resistant genes of M. tuberculosis in patients with spinal tuberculosis. This method may provide critical evidence for the clinical treatment of tuberculosis when it is applied in combination with bacterial culture.

7-year follow-up after open reduction and internal screw fixation in Bennett fractures.
Bennett fractures are unstable, and, with inadequate treatment, lead to osteoarthritis, weakness and loss of function of the first carpometacarpal joint. This study focuses on long-term functional and radiological outcomes after open reduction and internal fixation. ⋯ Good clinical results could be observed, if successful reduction of the fracture was achieved and maintained. However, there was no correlation between the accuracy of the fracture reduction considering a gap and step <2 mm and the development of arthritis.
