Treatment of chronic osteomyelitis (COM) remains challenging and often results in large bone defects. Dead space management and proper defect filling are essential for successful treatment. Bioactive glass S53P4 (BAG-S53P4) is an anorganic bone graft substitute with antibacterial, osteoconductive, osteostimulative and angiogenic properties. The aim of our study was to analyse the outcome of patients with COM and infected non-unions, whose bone defects were filled with BAG-S53P4. ⋯ The use of BAG-S53P4 in patients with COM and infected non-unions is promising. Adequate debridement and proper defect filling are necessary. BAG is well tolerated. X-ray examinations showed a thickened neo-cortex. The antibacterial effect is not mediated by antibiotics and is advantageous in times of evolving antibiotic resistance. High quality studies with a longer follow-up are required.

In the treatment of metatarsal fractures, the objective is early restoration of the physiological painless function of the foot. While undisplaced metatarsal fractures can be treated non-surgically, displaced fractures are a valid indication for reduction and internal fixation. Whereas plate fixation may lead to soft tissue irritation involving tendon adhesions and scar formation, retrograde percutaneous pinning may harm the intact metatarsophalangeal joint and lead to joint stiffness. We have therefore used the technique of elastic stable intramedullary nailing (ESIN) with titanium elastic nails (TEN) to achieve minimally invasive, antegrade splinting of short metatarsal shaft and neck fractures. ⋯ Antegrade, minimally invasive, elastic stable intramedullary nailing of short metatarsal shaft and neck fractures using titanium nails (TEN) is a safe surgical procedure and achieves primary functional stability. It reliably leads to fracture healing and produces good functional results.

Comparative Study
[Unstable pertrochanteric femur fractures. Failure rate, lag screw sliding and outcome with extra- and intramedullary devices (PCCP, DHS and PFN)].
The dynamic hip screw (DHS) often shows a high incidence of therapeutic failure and an impared outcome in the treatment of the unstable pertrochanteric femur fracture (31A2). Therefore often an intramedullary device is recommended. In a retrospective clinical study we examined whether the percutaneous compression plate (PCCP, Gotfried) provides advantages following unstable fractures in comparison to DHS and PFN. ⋯ Using the minimally invasive PCCP technique in unstable pertrochanteric femur fractures provides a promising therapy option especially with regard to surgical time, radiographic screening time and failure rate. Lag screw sliding was low. There was no advantage of the intramedullary device PFN.

The ideal treatment for massive rotator cuff tears is influenced by the morphology and chronicity of the tear, tissue quality, the degree of concomitant osteoarthritis, and patient-specific factors. Traditionally, massive rotator cuff tears have wrongly been equated with irreparable tears. ⋯ This study provides an overview of the current treatment options for large and massive rotator cuff tears, including their expected outcomes. Finally, a possible treatment algorithm is suggested.

Gluteal tendinopathy as well as partial and full-thickness tears of gluteal tendons (gluteus minimus and/or medius tendon) were underestimated as a cause of chronic pain in the past, and treatment was most commonly based on the diagnosis of trochanteric bursitis. Tendinous pathologies can either stay asymptomatic or cause pain and muscular dysfunction, not necessarily being associated with osteoarthritis of the hip 1. As the terminus "rotator cuff tear of the hip" was published in 1997 2, its aetiopathogenesis was reconsidered, resulting in improvements in diagnosis and treatment. ⋯ The effectiveness of extracorporeal shock wave therapy has also been proven 14. Surgical intervention is necessary in case of non-responsiveness to treatment or loss of gluteal muscular function. Hereby, the open gluteal repair always represented the method of choice, whereas recently, users of endoscopic systems reported similar or even better outcomes 15, 16, 17, 18, 19, 20, 21.
