Tibial spine avulsion fractures are mostly a paediatric injury which appropriate treatment is currently debated in literature. The choice between conservative and surgical treatment is based on the radiographic classification of Meyers-McKeever. The most diffused surgical techniques involve either internal fixation devices (screws) or bone tunnels fixation with resorbable sutures. Today, a third option is represented by resorbable magnesium screws which could combine the best features of the two classical systems. Objective of this study is to investigate the efficacy of these new devices in the surgical treatment of tibial spine avulsions. ⋯ The treatment of tibial spine avulsion fractures with arthroscopic reduction and internal fixation (ARIF) technique by magnesium resorbable screws seems to result in an excellent functional recovery without complications related to fixation devices, which were completely resorbed after 6 months and replaced by newly formed bone after 12 months. This new method could be considered as an alternative option to classic techniques by non resorbable fixation devices or bone tunnel fixation. Further studies are needed in order to evaluate the efficacy of these new devices in a wider group of patients.

Comparative Study
Treatment of fractures of the tibial plateau (Schatzker VI) with external fixators versus plate osteosynthesis.
The purpose of this study was to determine the effectiveness of circular external fixation (CEF) as a definitive treatment option for patients with complex tibial plateau fractures (Schatzker VI) compared with the outcomes of a fixed angle locking plates' group. ⋯ Definitive fixation with circular external fixator is effective in complex Schatzker VI tibial plateau fractures. Advantages include maintaining the frame till union, reduced risk of infection, early mobilization, restoration of the normal lower extremity alignment, versatility, and improved union rate in patients with multiple traumatic injuries, infection, and soft tissue injuries.

Metastatic lesions to the proximal femur occur frequently and require special consideration due to the high risk of pathologic fractures. Type of surgery might influence patient survival considering the growing concept of oligometastases. In fact, the use of modular tumor megaprosthesis is increasing in the last decades compared to intramedullary nailing. Aim of this study was to evaluate oncological and functional results of treatment in patients with pathologic or impending fracture of the proximal femur, with patient survival being the primary, complications the secondary, and functional results the tertiary endpoint. ⋯ Modular tumour prosthesis for proximal femur replacement provides good functional outcome, relative low incidence of complications and higher life quality in the medium term. Oncologic results were influenced by type of surgery, biased by the correct indications for resection and nailing. Preoperative general health condition, life expectancy and ambulatory capacity may influence treatment strategy. With the numbers available, the patients with actual pathologic or impending fracture of the proximal femur treated with resection had a significantly higher survival, especially those with metastases from renal carcinoma or multiple myeloma.

Multicenter Study Comparative Study
Unlocked versus dynamic and static distal locked femoral nails in stable and unstable intertrochanteric fractures. A prospective study.
Few clinical studies have analyzed the utility of distal interlocking screws in stable and unstable intertrochanteric fractures treated with intramedullary devices. We performed a prospective analysis comparing short unlocked versus short dynamic and short static distal locked intramedullary nails. ⋯ This clinical study further confirms the hypothesis that short intramedullary nails do not need to be locked for stable and unstable intertrochanteric fractures.

Intramedullary (IM) nail fixation is a common operative treatment, yet concerns regarding the frequency of complications, such as nonunion, remain. Treatment of tibial shaft fractures remains a challenge, and little evidence of prognostic factors that increase risk of nonunion is available. The aim of this study was to develop a predictive model of tibial shaft fracture nonunion 6 weeks after reamed intramedullary (IM) nail fixation based on commonly collected clinical variables and the radiographic union score for tibial fractures (RUST). ⋯ Three variables predicted nonunion. Based on these variables, we created a clinical prediction tool of nonunion that could aid in clinical decision making and discussing prognosis with patients.
