An unusual cause of radial nerve palsy

引用

Chinese Journal of Traumatology 2014年第3期17卷 175-177页

作者： Hemendra kumar Agrawal Vipin Khatkar Mohit Garg Balvinder Singh Ashish Jaiman vinod kumar sharma Central Institute of Orthopedics VMMC andSafdarjung Hospital New Delhi 110029 India

Neurapraxia frequently occurs following traction injury to the nerve intraoperatively, leading to radial nerve palsy which usually recovers in 5-30 weeks. In our case, we had operated a distal one-third of humeral shaft fracture and fixed it with 4.5 mm limited contact dynamic compression plate. The distal neurovascular status of the limb was assessed postoperatively in the recovery room and was found to be intact and all the sensory-motor functions of the radial nerve were normal. On the second postoperative day, following the suction drain removal and dressing, patient developed immediate radial nerve palsy along with wrist drop. We reviewed the literature and found no obvious cause for the nerve palsy and concluded that it was due to traction injury to the radial nerve while removing the suction drain in negative pressure.

Cosmetic arm lengthening with monorail fixator

引用

Chinese Journal of Traumatology 2015年第3期18卷 170-174页

作者： Hemendra kumar Agrawal Balvinder Singh Mohit Garg Vipin Khatkar Sumit Batra vinod kumar sharma Central Institute of Orthopaedics. Safdarjung Hospital New Delhi 110029 India

Upper limb length discrepancy is a rare occurrence. Humerus shortening may need specialized treatment to restore the functional and cosmetic status of upper limb. We report a case of humerus lengthening of 9 cm with a monorail external fixator and the result was observed during a 2-year follow-up. Humerus lengthening needs specialized focus as it is not only a cosmetic issue but also a functional demand. The monorail unilateral fixator is more functional and cosmetically acceptable, and thus becomes an effective treatment option.
