RÉSUMÉ
PURPOSE: The purpose of this study was to investigate differences in component alignment between first and second knees in simultaneous bilateral total knee arthroplasty (SBTKA) and unilateral TKA (UTKA). MATERIALS AND METHODS: 274 SBTKAs and 198 UTKAs were included in study. Patients were divided into three groups as SBTKA on the right knee (group A), SBTKA on the left knee (group B) and UTKA (group C). Femoral and tibial component alignment was checked in both coronal plane (alpha [α] and beta [β] angles) and sagittal plane (gamma [γ] and delta [δ] angles) radiographs. RESULTS: There were no statistically significant differences among groups in the preoperative anatomical varus angle and Kellgren–Lawrence gonarthrosis classification grade (p=0.139 and p=0.329, respectively). In the coronal plane, the alignment of femoral component (α angle) and tibial component (β angle) was similar in all three groups (α angle, 95.01 vs. 95.14 vs. 94.9, p=0.945; β angle, 90.03 vs. 89.67 vs. 89.98, p=0.483). The sagittal plane alignment of femoral component (γ angle) and tibial component (δ angle) did not show significant differences (γ angle, 7.04 vs. 6.98 vs. 7.00, p=0.132; δ angle, 86.56 vs. 87.41 vs. 86.73, p=0.610). CONCLUSIONS: The angular alignment of components was similar between SBTKA and UTKA.

Objective: To evaluate the results of shish kabab osteotomies fixed with SIGN NAIL in long bone deformities of patients suffering from osteogenesis imperfect
Methods: This study was carried out on 12 patients who presented in OPD or Emergency Department with deformities of long bones. Detailed history, examination and investigations including X-ray AP and Lateral view of involved bone were done. All these cases were treated with Shish Kabab Osteotomies and SIGN NAILunder spinal or general anaesthesia. These cases were followed up for up to average of 20 months [range 06 months -6 years ] and results of the nail were observed in terms of union, rehabilitation and complications
Results: It was found that 8 [66.7%] were male and 4 [33.3%] were females with a mean age of 14.83 +/- 5.24. 5 [41.7%] patients having age 10-15 years and 7 [58.3%] were between 16-20 years. Total 21 surgeries performed. 3[25.0%] had surgery on unilateral femur,2 [16.7%] on unilateral tibia, 3[25.0%] on both unilateral tibia and femur,3 [25.0%] had surgery on bilateral tibia and 1[13.3%] with bilateral tibia and femur. The parents of all patients had a first degree consanguineous marriage. The mean hospital stay were 4.17 +/- 1.75 days. All osteotomies sites heal within 06 months, better bone densities, 1 Having recurrence of deformity and no fracture were found. Only two patients using walkers while remaining need no support for walking
Conclusion: Sign Nail along with shish kabab osteotomies in deformities of osteogenesis imperfecta is the treatment of choice. Patient rehabilitation is early, hospitalization is short, and osteotomies site healing response is good as well as decrease risk of fracture
RÉSUMÉ
Objective: To find the outcome of bipolar hemiarthroplasty using posteriolateral and lateral approaches
Study design: Descriptive case series
Place and Duration of study: Departments of Orthopaedics and Spine Centre, Ghurki Trust Teaching Hospital Lahore, from January 2015 to December 2016
Methodology: Patients of either sex and of age above 40 year, who presented in Emergency Department with femoral neck fractures, were included in the study. Data included basic demorgraphic profile, Harris hip scoring, duration of surgery, hospital stay and blood loss
Results: A total of 200 patients were included in the study. There were 77 [38.5%] males and 133 [61.5%] females. Male to female ratio was 0.58:1 with mean age of 58.2 +/- 6.02 year. Mean follow up was 14.2 +/- 2.5 months. In 134 [67.0%] patients there was history of fall, 41 [20.5%] presented with fracture after low energy vehicle accident, 20 [10.0%] presented after high energy vehicle accident. Duration of surgery and blood loss were less in posteriolateral approach. The complication rate and Harris hip scoring was similar in both the approaches
Conclusions: Outcome of surgery in terms of infection, mobility and pain as well as dislocations were similar in both the approaches. The posterior approach was superior in terms of short duration of surgery and less blood loss
RÉSUMÉ
Objective: to determine the outcome of bone marrow injection in fractures with signs of delayed union and nonunion in terms of clinical and radiological evidence of union
Study design: descriptive case series
Place and Duration of study: department of Orthopedics and Spinal Surgery, Ghurki Trust Teaching Hospital Lahore, from October 2014 to May 2015
Methodology: patients admitted with nonunion or delayed union were included in the study. After evaluation and taking informed consent bone marrow was taken from the iliac crest with the help of bone marrow biopsy needle and injected at the site of fracture with the aid of lumbar puncture [LP] needle under image guidance. Repeat injection was given at three month interval, if needed. Clinical and radiological evidence of bone healing was assessed at six weekly follow ups till six months
Results: a total of 80 patients were included. There were 48 males and 32 females. There were 42 tibial, 18 femoral, 11 radius/ulna and 9 humeral fractures. Sixty-two procedures under local anesthesia and eighteen under short sedation were performed. In 67 patients union occurred following injection. The mean healing time was 16 weeks
Conclusion: percutaneous bone marrow injection is an alternative treatment of choice for delayed union and nonunion for long bone fractures

Conclusion: Home-made negative pressure dressing was a valuable therapy in the management of acute injuries of lower limb as it resulted in granulation and healing of the wound under challenging conditions
RÉSUMÉ
To determine the outcome of intramedullary interlocking surgical implant generation network [SIGN] nail in diaphyseal tibial fractures in terms of union and failure of implant [breakage of nail or interlocking screws]. Case series. Orthopaedics and Spinal Surgery, Ghurki Trust Teaching Hospital, Lahore Medical and Dental College, Lahore, from September 2008 to August 2009. Fifty patients aged 14 - 60 years, of either gender were included, who had closed and Gustilo type I and II open fractures reported in 2 weeks, whose closed reduction was not possible or was unsatisfactory and fracture was located 7 cm below knee joint to 7 cm above ankle joint. Fractures previously treated with external fixator, infected fractures and unfit patients were excluded. All fractures were fixed with intramedullary interlocking SIGN nail and were followed clinically and radiographically for union and for any implant failure. Forty one [88%] patients had united fracture within 6 months, 5 [10%] patients had delayed union while 4 [8%] patients had non-union. Mean duration for achieving union was 163 + 30.6 days. Interlocking screws were broken in 2 patients while no nail was broken in any patient. Intramedullary interlocking nailing is an effective measure in treating closed and grade I and II open tibial fractures. It provides a high rate of union less complications and early return to function
