Sensory Hypoinnervation In Club Foot, M Ahmed, N Ahmed, K. M. Khan, Masood Umer, H. Rashid,, Pervaiz Hashmi

Department of Surgery Docs

Abstract

We have compared the density of nerve fibres in the synovium in club foot with that of specimens obtained from the synovium of the hip at operations for developmental dysplasia. The study focused on the sensory neuropeptides substance P; calcitonin gene-related peptide; protein gene product 9.5, a general marker for mature peripheral nerve fibres; and growth associated protein 43, a neuronal marker for new or regenerating nerve fibres. In order to establish whether there might be any inherent difference we analysed the density of calcitonin gene-related peptide-positive nerve fibres in the hip and ankle joints in young rats. Semi-quantitative …

Predictors Of Paralysis In The Rheumatoid Cervical Spine In Patients Undergoing Total Joint Arthroplasty., Jonathan N Grauer, Edwin M Tingstad, Nahshon Rand, Michael J Christie, Alan Hilibrand

Rothman Institute Papers

BACKGROUND: Rheumatoid arthritis is sometimes associated with radiographic evidence of instability of the cervical spine, most commonly an abnormal subluxation between vertebrae. When this instability compromises the space that is available for the spinal cord, it may be predictive of paralysis. However, the prevalence of radiographic signs of instability that are predictive of paralysis among patients with nonspinal orthopaedic manifestations of rheumatoid arthritis is unknown.

METHODS: Radiographs of the cervical spine of patients with rheumatoid arthritis who had undergone total joint arthroplasty over a five-year period were retrospectively reviewed. The radiographs were evaluated for predictors of paralysis (a posterior atlantodental …

Chance-Type Flexion-Distraction Fracture Of Lumbar Spine, Arshad A. Siddiqui, Ahmad Ali Shah

Section of Neurosurgery

A case of a twenty years old male who had been hit by a van at the lower back, presented two weeks later with complete paraplegia and double incontinence is presented. Radiological imaging revealed shearing of spine with fracture line slicing through the second lumbar (L2) vertebra going across all the three vertebral columns with complete retrolisthesis of upper fragment. He was managed conservatively with immobilization and rehabilitation.

Comparison Of Transcranial Electric Motor And Somatosensory Evoked Potential Monitoring During Cervical Spine Surgery., Alan S Hilibrand, Daniel M Schwartz, Venkat Sethuraman, Alexander R Vaccaro, Todd J Albert

Rothman Institute Papers

BACKGROUND: There has been little enthusiasm for somatosensory evoked potential monitoring in cervical spine surgery as a result, in part, of the increased risk of motor tract injury at this level, to which somatosensory monitoring may be insensitive. Transcranial electric motor evoked potential monitoring allows assessment of the motor tracts; therefore, we compared transcranial electric motor evoked potential and somatosensory evoked potential monitoring during cervical spine surgery to determine the temporal relationship between the changes in the potentials demonstrated by each type of monitoring and neurological sequelae and to identify patient-related and surgical factors associated with intraoperative neurophysiological changes.

Operative Treatment Of Bilateral Hip Dislocation In Children With Arthrogryposis Multiplex Congenita, S Asif, Masood Umer, Rashid Baig

Department of Surgery Docs

Abstract

PURPOSE:

Arthrogryposis multiplex congenita (AMC) is a rare syndrome with multiple joint contractures. It is commonly believed that bilaterally dislocated hips associated with joint contractures should not be reduced, because movement is satisfactory, while open reduction leads to poor results. This report presents our experience with surgical management of bilateral dislocation of hips in children with AMC.

METHODS:

During the period 1990 to 2000, we performed open reduction on 8 hips of 4 children with AMC. The mean age at surgery was 23 months (range, 5-48 months). Open reduction and capsular plication without any bony procedure were performed in …

An Experience With Free Scapular Flap For Reconstruction Of Lower Extremity Defects At Aga Khan University Hospital Karachi, Pervaiz Mehmood Hashmi

Section of Orthopaedic Surgery

Background: Reconstruction of large composite tissue defects with exposed vital structures and weight bearing surfaces are extremely difficult for reconstructive surgeons. Coverage of such difficult defects can be achieved with free tissue transfer provided microsurgical expertise is available. This study was carried out to determine the outcome of free scapular flaps performed for lower extremity defects.
Methods: Clinical records of the patients were reviewed and important variables included demographic data, etiology of soft tissue defects, site and size of defect, complications and percentage of wound coverage by flap. Patient satisfaction and objective assessment of flap coverage and motion of involved …
