Influence of age on the outcome of single stage reconstructive surgery for congenital dislocation of the hip joint.

OBJECTIVE: This study was conducted to assess the effect of age on the ultimate outcome measures following single stage surgical procedure of soft tissue release, relocation, capsulorrhaphy, femoral shortening with varus/derotation osteotomy and pelvic osteotomy. STUDY DESIGN: A case series. PLACE AND DURATION OF STUDY: The study with two groups of pretest-posttest design was conducted at Department of Orthopaedic Surgery, Jinnah Postgraduate Medical Centre (JPMC), Karachi, from 1993 to January 2008. METHODOLOGY: Patients included were having neglected, congenital dislocation of the hip joint, aged over 3 years. Patients with failed previous surgery, paralytic, teratological, traumatic or septic dislocations and patients with less than 5 years follow-up were excluded from the study. The patients were divided into two groups, 3-7 years (37 hip joints) and over 7 years (13 hip joints). The single stage surgical procedure of open relocation, femoral shortening/derotation/ varus osteotomy and pelvic osteotomy was the dependent variable; whereas, the final clinico-radiological results based upon Tonnis grading, Severin's clinical/radiological grading, Klisic's overall rating and acetabular index were the independent variables of the study. Pre- and postoperative data was assessed for overall improvement and the difference in outcome measures between the two age groups. RESULTS: Significant overall improvement on all parameters was achieved after surgery. When results were compared between two age groups, there was no significant difference in the final outcome as per Tonnis grading and Severin's clinical typing as modified by Gibson (97.3% versus 84.4% normal hip joints or Tonnis grade 1 and 78.37% versus 53.85% Severin's type 1) but the results based upon Severin's radiological grading (62.16% versus 15.38%) and Klisic's overall rating (62.16% versus 15.38%) were significantly better in 3-7 years as compared to those over 7 years. There was no significant difference between the two age groups when compared for improvement in acetabular index. On further analysis, a progressive deterioration of results with increasing age was observed, yet the results in those aged over 7 years were reasonably justified surgical correction of congenital dislocation of the hip joint. Majority of the complications were seen in children operated at the age of 4-5 years. There were 7 cases (14%) of redislocation/subluxation and 6 were in 3-7 years age group. There were 4 cases (8%) of the avascular necrosis of the femoral head. Three patients had residual coxa vara and 2 had significant limb shortening. Limb lengthening was done in these 2 cases. CONCLUSION: The final results displayed progressive deterioration of clinical, radiological and functional outcome measures with aging after single stage reconstructive surgery for the congenital dislocation of hip joint. However, despite this, the results in children over 7 years were also good/excellent in most of the cases justifying surgery.

Human cost of political violence.

OBJECTIVE: To evaluate the cost of political violence in terms of human life and its influence on social, psychological and financial aspects of community. DESIGN: Retrospective study conducted from 1987 to 1989. SETTING: Department of Accident and Emergency, Jinnah Postgraduate Medical Centre, Karachi. SAMPLE SIZE: Nine hundred and fifty four victims including two hundred and fifty seven dead. RESULTS: The mean age of the victims was 27.29 +/- 9.46 years with a male to female ratio of 33:1. All ethnic groups suffered to some extent. No case of violence on religious differences was reported during this period. Firearms were frequently used. Most of the deaths (92.2%) occurred due to firearm injuries. Landhi, Korangi, Malir and Shah Faisal Colony were the worst affected areas. There was however no significant difference between them. The projected loss of life for the dead was approximately 3.15 million days. The same was difficult to assess for the injured because of multifactorial reasons. Six thousand four hundred and ninety two close family members suffered from Psychological and Physical Trauma. The number of distant members affected psychologically was estimated to be 0.566 million. Schooling of approximately five thousand four hundred thirty seven children of the victims suffered. CONCLUSION: Political violence has significant short and long term effects on the society in terms of physical and psychological trauma, financial losses, poor schooling and health, biased pattern of child development, migration of families and further division of society into identifiable communities which may prolong the conflict.

Extensor mechanism sparing approach to the elbow for reduction and internal fixation of intercondylar fracture of the humerus.

OBJECTIVE: To evaluate the short term results of extensor mechanism sparing approach to the elbow for fixation of intercondylar fractures of the distal end of humerus and compare it with existing Surgical approaches. DESIGN: This is a prospective study conducted from June, 1992 to June, 1997. SETTING: Department of Orthopaedic Surgery, Jinnah Postgraduate Medical Centre and Mehran Clinic (Pvt.), Karachi. PRINCIPLE OF SURGICAL APPROACH: This approach is based upon the principle that by sparing the extensor mechanism, we reduce the amount of surgical trauma and help in early rehabilitation which can contribute in improving the results of this difficult fracture. RESULTS: There were nine type 2 fractures, eight type 3 fractures and four type 4 fractures according to Rise borough and Radin classification. Based upon the same authors criteria, there were over all 57.14% good 23.81% fair and 19.04% poor results. Adequate exposure was achieved in all of type 2 and seven (87.5%) out of eight type 3 fractures. We failed in type 4 fractures. Mean operating time was 107.38 (+/- 24.67) minutes. CONCLUSION: The results in this series are comparable to other studies. They can however be improved with proper selection of cases, experience with the technique along with better fixation and rehabilitations.
