Four parts inter trochanteric fracture of femur are commonest in elderly people. DHS fixation is gold standard treatment of such fractures. Various Complications of DHS implant are reported in the literature. However, Hip Instability: Subluxation and Dislocation is very rare. We report, five cases of Hip instability following DHS fixation surgery. This is a retrospective study conducted at ACPM Medical College, Dhule. We found only five cases that developed hip instability after DHS fixation since 1997. Available clinical notes and X-rays of these patients were studied to get the relevant information.Introduction
Materials and Methods
We have studied the case records of 16 patients with dislocations of the cervical spine who deteriorated neurologically during or after reduction. The dislocations were reduced by skull traction in four patients, by manipulation in four and by operation in seven. This complication was not related to age, sex, mechanism of injury, or the level and the type of dislocation. Fourteen patients made substantial recoveries, one made a partial recovery and one patient remained totally paralysed and died three months later. The causes and prevention of spinal-cord damage at this stage of management are discussed, and the early use of MRI or CT myelography is recommended.
We report 13 patients with missed bilateral facet dislocation of the lower cervical spine who subsequently developed severe spinal-cord involvement. There were more women and the patients were older than in most groups with spinal injury. The commonest cause was a fall, and paralysis appeared from six to 48 hours after injury in most patients. Ten patients made some recovery after late reduction but three remained totally paralysed. We discuss the pathogenesis of the late cord lesion and the reasons for delay in diagnosis.
