Overtreatment of displaced midshaft clavicle fractures : A survey of hospitals in Sweden, Denmark, and Finland

Background and purpose The best treatment for displaced clavicle fractures has been debated for decades. Operative treatment has become more common. However, several randomized trials comparing non-operative and operative treatment have not shown any compelling evidence in favor of surgery. We identified the preferred treatment of displaced midshaft clavicle fractures at public hospitals in 3 countries in Scandinavia.Patients and methods A purpose-made multiple-choice questionnaire in English was sent to all public hospitals in Denmark, Sweden, and Finland. This was addressed to the orthopedic surgeon responsible for treatment of clavicle fractures, and completed questionnaires were obtained from 85 of 118 hospitals.Results In the 3 countries, 69 of the 85 hospitals that responded would treat displaced clavicle fractures operatively. Clear criteria for treatment allocation were used at 58 of the hospitals, with the remaining 27 using individual assessment in collaboration with the patient. Precontoured locking plates were mostly used, placed either superiorly (64/85) or anteriorly (10/85).Interpretation Displaced midshaft clavicle fractures are mainly treated operatively in Sweden, Denmark, and Finland. This treatment is not supported by compelling evidence.Peer reviewe

Nonunion - consensus from the 4th annual meeting of the Danish Orthopaedic Trauma Society

CITATION: Schmal, H. et al. 2020. Nonunion – consensus from the 4th annual meeting of the Danish Orthopaedic Trauma Society. EFORT Open Reviews, 5:46-57, doi:10.1302/2058-5241.5.190037.The original publication is available at https://eor.bioscientifica.comNonunions are a relevant economic burden affecting about 1.9% of all fractures. Rather than specifying a certain time frame, a nonunion is better defined as a fracture that will not heal without further intervention. Successful fracture healing depends on local biology, biomechanics and a variety of systemic factors. All components can principally be decisive and determine the classification of atrophic, oligotrophic or hypertrophic nonunions. Treatment prioritizes mechanics before biology. The degree of motion between fracture parts is the key for healing and is described by strain theory. If the change of length at a given load is > 10%, fibrous tissue and not bone is formed. Therefore, simple fractures require absolute and complex fractures relative stability. The main characteristics of a nonunion are pain while weight bearing, and persistent fracture lines on X-ray. Treatment concepts such as ‘mechanobiology’ or the ‘diamond concept’ determine the applied osteosynthesis considering soft tissue, local biology and stability. Fine wire circular external fixation is considered the only form of true biologic fixation due to its ability to eliminate parasitic motions while maintaining load-dependent axial stiffness. Nailing provides intramedullary stability and biology via reaming. Plates are successful when complex fractures turn into simple nonunions demanding absolute stability. Despite available alternatives, autograft is the gold standard for providing osteoinductive and osteoconductive stimuli. The infected nonunion remains a challenge. Bacteria, especially staphylococcus species, have developed mechanisms to survive such as biofilm formation, inactive forms and internalization. Therefore, radical debridement and specific antibiotics are necessary prior to reconstruction.Publisher's versio

Locking plate osteosynthesis of clavicle fractures:complication and reoperation rates in one hundred and five consecutive cases

PURPOSE: Locking plate osteosynthesis has become the preferred method for operative treatment of clavicle fractures. The method offers stable fixation, and would theoretically be associated with a low rate of fracture-related complications and reoperations. However, this remains to be explored in a large cohort, and our purpose was to assess the overall rates of complications and reoperations following locking plate osteosynthesis of mid-shaft clavicle fractures. METHODS: We identified all locking plate osteosynthesis of mid-shaft clavicle fractures operated upon in our department from January 2008 to November 2010 (n = 114). Nine patients did not attend the follow-up at our institution. The study group of 105 fractures (104 patients, 86 males) had a median age of 36 years (14–75 years). Follow-up ranged from 0.5 to 3.5 years. No patients were allowed to load the upper extremity for six weeks. By studying patient files and radiographic material, we assessed complications and reoperations. RESULTS: Overall, there were 31 cases (30 %) of plate removals for discomfort. There were five cases (5 %) of failure of osteosynthesis: two occurred early after approximately six weeks and three late after ten to 13 months postoperatively. CONCLUSION: The overall rate of failure of osteosynthesis is low (5 %). The burden of plate removals in approximately one third of patients should be included in the preoperative information
