Abstract: Objective: To present experience of soft tissue cover of lower one third of tibia and ankle treated by an orthopaedic surgeon without the presence of a plastic surgeon but of course, depending on the reliability of this flap.
Patients and Methods: Nineteen patients, fifteen males and four females, with soft tissue defect of lower one third tibia and ankle requiring soft tissue cover were treated from April 2002 to September 2005. The flap was outlined at the posterior aspect of junction of upper and middle 1/3 leg.
The pivot point of the pedicle was at least 5cm i.e., 3 fingers’ breadth above the lateral mallelous to allow anastomosis with the peroneal artery. Skin incision was started along the line in which the fascial pedicle would be taken. The sub dermal layer was dissected to expose the sural nerve, accompanying superficial sural vessels and short saphenous vein. The subcutaneous fascial pedicle was elevated, with a width of 2cm to include the nerve and these vessels. At the proximal margin of the flap, the nerve and the vessels were ligated and severed. The skin island was elevated with the deep fascia. The donor site defect was closed directly when the flap was less than 3cm wide. A larger donor site defect along with the pedicle was covered with a split thickness skin graft.
Results: All flaps except two survived. Most flaps showed slight venous congestion which cleared in a few days. There was no loss of split skin graft & none was lost to follow up.
Conclusion: Distally based Sural artery flap remains the choice for reconstruction of soft tissue defects of lower 1/3 tibia and ankle. The dissection is easy, quicker and can be done by an orthopaedic surgeon already involved in flap surgery; without the presence of plastic surgeon.

Abstract: Introduction: Talipes equino varus TEV is one of the most common congenital anomaly. It is managed by some common ways i-e., conservative & surgical methods. Among surgical methods are Turco’s posterior medial release, posterior soft tissue release operation (Attenborough), four quadrant release (Mc Kay). Objective of this study was to determine the reliability of surgical option like postero medial release in children having congenital TEV.
Material & Methods: This study was carried out during the period from October 2002 to March 2005 in the Deptt. of Orthopaedics of PMCH Nawab Shah. The inclusion criteria were children 2 months to 30 months of age having moderate to severe club foot. Clubfoot secondary to some other disorder such as cerebral palsy, arthrogryposis multiplex congenital, myeldysplasia or DDH were not included in this study. The deformity was treated surgically in all cases by postero medial release. Follow-up period was one & half year.
Results: A total 57 patients were included in this study with the age range of 2 months-2.5 yrs with moderate to severe deformity. Forty two were male (73.7%) and 15 patients (26.3%) were female, seventeen patients (29.8%) had bilateral club foot while the rest the rest of 40 patients (67.1%) had unilateral deformity. Positive family history of club foot was in 10 patients (17.5%). Results were concluded on 57 patients who completed one & half year follow-up. Excellent results were observed in 41 patients (71.9%), good in 11 patients (19.2%), fair in 2 children (3.5%). No patients lost to follow up.
Conclusion: Children up to 30 months (2 months - 2.5 years) age with congenital TEV can be treated with surgery successfully.

Abstract: Introduction: Tendon Achilles is largest tendon of the body and is made of fibrous tissue, descends from calf & gets attached to calcaneum. The injuries of this strongest tendon are not only uncommon but disabling as well. Twenty one tendons in 20 patients were managed successfully using Bosworth repair in the department of Orthopaedics NMC Hospital NawabShah during the period from March 2002 to April 2006.
Patients & Method: All patients were male and age ranged from 25 years to 55. Thirteen injuries were caused due to direct trauma, 3 patients noticed sudden jerk during high jump while playing, 3 had fall while running on plain ground and use of prolong corticosteroids caused 2 bilateral tendon injuries in one patient (Figure 1). Eleven patients sustained right side injury while 9 had their left side tendon injury. All patients were admitted through OPD & Emergency departments and were operated after their pre-op work & anesthetist’s fitness was completed. Period lapsed from injury to admission was one day to 3 months and surgery was performed within 1day to 6 days after their admissions (Figure 3).
Results: All twenty patients healed completely. Out of these 20 patients 17 were farmers, one medical professional and two were agriculture mechanics (Figure 4). Follow-up period in all these patients was over 15 months and no patient lost to follow- ups.
Conclusion: Public awareness service programs and interaction between Orthopaedic consultants and other health professionals including general practitioners of the areas can prevent not only delay in diagnosing such problems, but shall minimize the ailment suffered by these patients. Nevertheless, all injuries of tendon Achilles should be dealt immediately to restore the full function of this strongest tendon of body regardless the lapse of any length of time.

Abstract: Many insects are known to give response in adaptive way for seasonal changes in day lengths. Photoperiod control’s many developmental responses and allows insects to survive periods of unfavorable environmental conditions. An experiment was conducted to study the effect of different photoperiod lengths on biological parameters of green lacewing, Chrysoperla carnea. Four different photoperiod regimes were selected with varying lengths of light/dark hours (8/16, 10/14, 24/0 and 0/24) at a constant 26±2°C temperature with 70 % RH (relative humidity) in the laboratory. Photoperiod regimes affected the development of C. carnea from egg to adult. In complete darkness (L: 0 D: 24), minimum egg laying, hatching, larval survival and adult emergence were recorded. Incubation period for eggs, larval period and pupal duration were also significantly longer in complete darkness as compared to other treatments 8L: 16D and 10L: 14D. Whereas, the treatment with complete light hours (L: 24, D: 0) resulted in maximum egg laying hatching, larval survival and adult emergence. The incubation period for eggs, larval and pupal duration significantly shortened as compared to other treatments.Sex ratios skewed towards female when full light hours were provided for development.
