Atlantoaxial Fixation

Atlantoaxial instability often requires surgical treatment. Several techniques are available to perform antlantoaxial stabilization, and all of these have their different advantages and disadvantages. In 2004, Wright described the C2translaminar screw fixation, which offers rigid fixation but without the technical demands of C2 pars placement and eliminates the risk of vertebral artery injury. The aim of this study is to review the C2 translaminar screw fixation technique, emphasizing operative details, risks and benefits comparing with the others atlantoaxial fixation techniques.

Background: Tarsometatarsal (TMT) arthrodesis is a common operative procedure for end-stage arthritis of the TMT joints. To date, there is no consensus on the best fixation technique for TMT arthrodesis and which joints should be included. Methods: Thirty fresh-frozen feet were divided into one group (15 feet) in which TMT joints I-III were fused with a lag screw and locking plate and a second group (15 feet) in which TMT joints I-III were fused with 2 crossing lag screws. The arthrodesis was performed stepwise with evaluation of mobility between the metatarsal and cuneiform bones after every application or removal of a lag screw or locking plate. Results: Isolated lag-screw arthrodesis of the TMT I-III joints led to significantly increased stability in every joint ( P < .05). Additional application of a locking plate caused further stability in every TMT joint ( P < .05). An additional crossed lag screw did not significantly increase rigidity of the TMT II and III joints ( P > .05). An IM screw did not influence the stability of the fused TMT joints. For TMT III arthrodesis, lag-screw and locking plate constructs were superior to crossed lag-screw fixation ( P < .05). TMT I fusion does not support stability after TMT II and III arthrodesis. Conclusion: Each fixation technique provided sufficient stabilization of the TMT joints. Use of a lag screw plus locking plate might be superior to crossed screw fixation. An additional TMT I and/or III arthrodesis did not increase stability of an isolated TMT II arthrodesis. Clinical Relevance: We report the first biomechanical evaluation of TMT I-III arthrodesis. Our results may help surgeons to choose among osteosynthesis techniques and which joints to include in performing arthrodesis of TMT I-III joints.

The purpose of this study is to document the percutaneous Herbert screw fixation technique with free-hand method to stabilise acute unstable scaphoid fractures and evaluated the clinical results. Thirteen patients with less than 14 day-old fractures were fixed by percutaneous Herbert screw and reviewed retrospectively for a minimum of 24 months (average, 37 months). All were men with an average age of 22 years. According to Herbert's classification, all fractures were classified as of the acute unstable (B2). Fracture union was achieved in all cases at a mean of 9.2 weeks (eight to 12 weeks). Return to work or school ranged from one day to three weeks according to their occupation. This percutaneous fixation technique using Herbert screw is a reliable and effective alternative for acute scaphoid fractures, which enables the patient to use the hand earlier with high satisfaction and minimum complication.

Pull Out Suture

Avulsion fracture of flexor digitorum profundus (FDP) tendon is relatively rare fracture at the distal phalangeal base than avulsion fracture of terminal extensor tendon. Terminal extensor avulsion fracture, known as bony mallet finger, could be successfully treated by closed reduction and pinning, such as extension block technique. However, most of FDP avulsion fracture, known as Jersey’s finger, needed open reduction, because of the proximal migration of fracture fragment and difficulty of pin fixation. Up to date, most of FDP avulsion fractures were treated by open reduction and fixation by pull-out suture or suture anchor technique. We report a case of comminuted FDP avulsion fracture, successfully treated by open reduction and mini-plate and screw fixation technique.
