Ipsilateral mid-third clavicle fracture with grade V acromioclavicular joint dislocation

We report the case of a 20-year-old man with an ipsilateral mid-third clavicle fracture with grade V acromioclavicular joint (ACJ) dislocation. The combination of these two injuries is rare. A literature search produced various treatment algorithms. In this case, the patient was successfully treated with a Bosworth screw.This work was carried out in the Department of Orthopaedics, William Harvey Hospital, Ashford, Kent, UK     

Management of thoraco-lumbar fractures

The immediate surgical goals in the treatment of thoraco-lumbar fractures are decompression of compromised neural structures and stabilization of the vertebral column. If more sophisticated instrumentation is available, e.g. A.O.-fixateur interne or instrument set according to Kluger, stable reposition and reformation of compressed vertebral bodies also becomes possible. The long-term goals are to prevent delayed onset of spinal deformity, pain, and further neurological deficit. Early operative stabilization also shortens hospitalization time and allows immediate ambulation, thus lessening pulmonary, vascular, urological, and psychological complications. The Department of Neurosurgery, Sher-I-Kashmir Institute of Medical Sciences, treated 75 cases of thoraco-lumbar fractures. Out of 75 cases 63 were operated upon: 32 cases by spinal fusion alone and 31 by a combined procedure of decompression and posterior spinal fusion with fibular graft. 52 showed evidence of recovery ranging from moderate to excellent in a follow-up of 2-3 years. Thus surgery resulted not only in giving a stable spine to patients but also good improvement of neurodeficits. Our experiences demonstrate that operative treatment of thoraco-lumbar fractures can give satisfactory results even in situations where sophisticated instrumentation is not available.     

Occurrence of the t(2;5)(p23;q35) in non-Hodgkin's lymphoma

Primary CD30(Ki-1)-positive anaplastic large-cell lymphoma (ALCL) is considered by some to be a distinct clinicopathologic entity associated with the t(2;5) (p23;q35). However, the specificity of t(2;5) for ALCL has not been carefully studied. Therefore, we performed a detailed analysis of all cases of ALCL with abnormal cytogenetics results in the Nebraska Lymphoma Study Group registry, as well as all other cases of non-Hodgkin's lymphoma with t(2;5) in the registry. We found the t(2;5) in only five of 10 cases of ALCL, four of whom were young patients. However, we also found the t(2;5) in 11 other cases of nonanaplastic lymphoma, including eight children with typical peripheral T-cell lymphomas of various types. The t(2;5) was also found in three older adults with B-cell lymphomas of various types. Thus, the t(2;5) was not specific for CD30+ ALCL. However, t(2;5) may define a clinicopathologic entity in children and young adults characterized by variable morphologies with a T-cell or indeterminate phenotype, CD30-positivity, nodal disease with frequent extranodal involvement, advanced stage, and an excellent response to therapy, including bone marrow transplantation for relapsed disease. The clinical relevance of the t(2;5) in older patients requires further study.
