The role of joint replacement in the treatment of osteoarthritis of the thumb carpometacarpal joint is a subject of considerable controversy in the current literature. In German-speaking countries this technique is used much less frequently than resection procedures. Aseptic loosening of the prosthesis is believed to be the major cause of the high failure rates reported for cemented and uncemented types of implants. ⋯ Aseptic loosening is reported to be the major cause with failure rates of 50 % or more. Although a Norwegian study reported high 5 and 10-year survival rates for various thumb carpometacarpal joint prostheses according to the Norwegian arthroplasty registry, it did not recommend the widespread use of thumb carpometacarpal joint replacement at the present time. In our opinion, joint replacement may be considered as a possible treatment option for advanced osteoarthritis of the thumb carpometacarpal joint but it should not always be recommended because long-term results are inconsistent and similar functional outcomes have been reported for alternative surgical techniques, such as resection arthroplasty.

Review Meta Analysis
Risk factors which predispose first-time traumatic anterior shoulder dislocations to recurrent instability in adults: a systematic review and meta-analysis.
Recurrent instability following a first-time anterior traumatic shoulder dislocation may exceed 26%. We systematically reviewed risk factors which predispose this population to events of recurrence. ⋯ Sex, age at initial dislocation, time from initial dislocation, hyperlaxity and greater tuberosity fractures were key risk factors in at least two good quality cohort studies resulting in strong evidence as concluded in the GRADE criteria. Although bony Bankart lesions, Hill Sachs lesions, occupation, physiotherapy treatment and nerve palsy were risk factors for recurrent instability, the evidence was weak using the GRADE criteria-these findings relied on poorer quality studies or were inconsistent among studies.

ReviewMetatarsalgia, lesser toe deformities, and associated disorders of the forefoot.
Forefoot pain in the adult often alters mobility and has a negative impact on quality of life. Metatarsalgia describes pain localized to the forefoot. ⋯ In addition to lesser toe and metatarsal abnormality, forefoot pain can be attributed to interdigital neuritis, disorders of the plantar skin, and gastrocsoleus contracture. Treatment of these conditions may include shoe modifications, appliances, therapeutic exercises, and surgical repair.

Review Case Reports
[A rare complication of kyphoplasty is PMMA-cement loosening - case report and literature review].
For vertebral body fractures combined with strong back pain, the kyphoplasty is an established method for pain reduction. A balloon effects an excavation in the vertebral body, which will be filled up with cement. We distinguish between cements of polymethyl metacrylate (PMMA) and calcium phosphate. Their diverse chemical qualities enable different indications. ⋯ Injuries of the vertebral body frame cannot be operated exclusively with kyphoplasty. The reason for this is the instability of the vertebral body despite the injection of the PMMA cement. We advise to stabilise the spine in such cases with a dorsal internal fixator additively.

Locking plate osteosynthesis of proximal humeral fractures are widely recommended and used, even in complex intraarticular fracture patterns such as AO/OTA Type C fractures. We systematically reviewed clinical studies assessing the benefits and harms of osteosynthesis with angle stable plates in AO/OTA Type C fractures of the proximal humerus. ⋯ Insufficient study designs and unclear reporting preclude safe treatment recommendations. Complication and reoperation rates were unexpected high. Based on the studies included we cannot routinely recommend the use of locking plates in AO/OTA Type C fractures.
