Efficacy of Percutenous Trigger Finger Release

Objective: To determine the efficacy of trigger finger release with the percutaneous technique. Study Design: Cross-sectional study. Place and Duration of Study: Department of Orthopedic Surgery, Jinnah Post Graduate Medical Center, Karachi Pakistan, from Mar 2017 to Mar 2018. Methodology: One hundred and three patients were selected through the outpatient department after they meet the inclusion criteria with one or more trigger fingers in whom percutaneous release was indicated. Patients with previously open release, carpel tunnel syndrome, osteoarthritis of the hand and Dupuytren's contracture were excluded. Results: The mean age of patients was 34.79 ± 14.08 years with a range of 17-62 years. More patients were male (56.3%), and females were 43.7% with a male to female ratio of 1.27:1. Accordingly, 95 (92.2%) out of 103 had complete relief of symptoms and the procedure was thus efficacious in these patients. Among the remaining 7.8% of patients in whom it was not efficacious, about 2.2% had partial relief while 5.6% had either no benefit or worsening of symptoms as assessed on the 8th week post-operatively. Age was a significant effect modifier (p<0.05). Conclusion: Overall, the percutaneous technique of trigger finger release is an effective method of treatment

Frequency of osteoarthritis and functional outcome of operated tibial plateau fractures: A minimum of 5 years follow up

OBJECTIVE

Tibial plateau is an important weight bearing surface and its fractures are the result of axial compressive forces. Post-traumatic osteoarthritis (PTOA) occurs despite anatomical joint reconstruction. In this study we determined the incidence of PTOA after primary management of tibial plateau fractures and determined the risk factors of PTOA of patients whose results were published at 24 months and now we present a five year follow up of the same patients.

METHODS

In this study, we presented the prospective data of 109 patients who were managed for tibial plateau fractures, from August 2009 to June 2018 a Jinnah postgraduate medical centre. Data of patients regarding clinical and radiological, functional outcome (according to the American Knee Society criteria), post-procedural visual analogue scale (VAS) pain score was included. Incidence of development of PTOA was noted in each patient using the Ahlbäck classification.

RESULTS

Out of 109 patients with tibial plateau fractures, 81 (74.3%) were male and 28 (25.7%) were female. Mean time lag from injury to surgery was 10.14±9.07 days. Overall incidence of osteoarthritis was 50 (45.9%). Advanced age >50 years (odds ratio 9.1 (3.7-22.1), p-value <0.0001), female gender (odds ratio; 3.40 (1.36-8.46), p-value 0.007), VAS score >4 ((odds ratio; 73.28 (15.7-341.5), p-value <0.001)), Articular depression (odds ratio; 35.25 (11.49-108.1), p-value <0.001) and degree of mal-alignment (odds ratio; 25.72 (9.30-71.12), p-value <0.001) were found to be the risk factors of PTOA. While excellent functional outcomes were protective for PTOA (odds ratio; 4.8, p-value <0.001). Thirty out of fifty patients (60%) suffering from secondary arthritis of the knee required knee replacement (TKR). Twenty-one patients (70%) were males that underwent TKR.

CONCLUSIONS

There is a high proportion of osteoarthritis following tibial plateau fixation. The risk factors that related to the development of secondary arthritis our cohorts were increased age, male gender, a decrease in AKSS and a higher VAS group. Knee arthroplasty is the only option for our cohorts with severe posttraumatic arthritis.

Osetosynthesis of Fractures neck femur with cannulated screws: Evaluation of risk factors for post-operative complications

OBJECTIVE

To evaluate the risk factors for postoperative complications in fracture neck femur treated with cannulated screws.

METHODS

This cross sectional series was performed at the Department of Trauma and Orthopaedics, Jinnah Postgraduate Medical Centre, Karachi from January 2015 to December 2019. A Total of 149 patients with close fracture neck femur of either gender between 20-60 years of age were included in the study. Patients with hip arthritis and pathological fractures such as tumours were excluded. Minimum three cannulated screws were used to fix the fracture with parallel configuration in compression mode. Patients were followed and evaluated for fracture healing and related complications such as nonunion and Avascular necrosis for two years. Descriptive statistics were calculated and stratification was done. Post stratification chi square test was applied taking p-value ? ≤0.05 as statistically significant.

RESULTS

There were 113 (75.8%) male and 36 (24.2%)female patients. Mean age was 37.54±10.66 years. Mean operation time was 38.56±4.61 minutes. Out of these, 93 (62.4%) injuries were caused by motor vehicle accident, 34(22.8%) fall and 22(14.8%) by sports injury. Garden type III fracture was observed in 69 (46.3%) patients followed by 41 (27.5%) fractures of grade-IV. Fracture union was observed in 126 (84.6%) patients at a mean time of 4.0±1.1months and non-union in 23 (15.4%) cases whereas rate of avascular necrosis was noted in 28 (18.8%) cases and were significantly associated with age, injury mode, time from injury to surgery and fracture classification. Non-union was significantly associated with open reduction and delayed fixation of fracture for more than 24 hours.

CONCLUSIONS

Although cannulated screws are a universally accepted method of fixation for femoral neck fractures, the incidence of complications such as Avascular necrosis and non-union is quite high particularly in young males meeting a motor vehicle accident, undergoing open reduction for displaced fractures even with early diagnosis and treatment.

Plaster immobilization versus anterior plating for dorsally displaced distal radial fractures in elderly patients in Pakistan

This prospective, multi-centred, randomized trial examined outcomes of 3- and 12-month follow-ups of 159 elderly participants aged more than 75 years with isolated distal radial fractures, treated by anterior locking plate or closed reduction and cast immobilization. The primary outcome was the patient-rated wrist evaluation (PRWE) score. The PRWE score at 12 months was not significantly different between the two groups; however, the radiological outcomes and complications rates were worse in the casting group.Level of evidence: III.

A prospective evaluation of clinical and functional outcome of single bundle anatomic anterior cruciate ligament reconstruction with hamstrings autograft

A case series was conducted at the Department of Orthopaedic surgery, Jinnah Postgraduate Medical Centre, Karachi, from July 2016 to June 2018, to evaluate the functional and clinical outcome of arthroscopic anatomic anterior cruciate ligament (ACL) reconstruction with hamstrings autograft. Patients aged 17 years and above with anterior cruciate ligament (ACL) injuries of duration three months or older, diagnosed on history and clinical examination and confirmed on Magnetic Resonance Imaging were prospectively recruited from outpatient department. Patients with multiligamentous injury were excluded. Information on patient's demographics such as age, duration of injury and mechanism of injury were recorded. In addition, graft length and diameter, associated injuries of lateral or medical menisci were noted peroperatively. Patients were followed for a minimum of 12 months. The functional outcomes were assessed through lysholm knee score, and Tegner activity scale. Clinical outcome was assessed with loss of motion in flexion and extension and residual laxity using Lachman test. Paired sample t-test was applied to compare mean scores pre and post-operatively. The study findings reveal that arthroscopic anatomic Anterior Cruciate Ligament reconstruction using quadruple strand hamstring tendon autograft was an effective method of treatment for the ACL-deficient knee with improved clinical and functional status.

Delay in Initial Debridement for Open Tibial Fractures and Its Possible Impact on Patient Outcomes: A Single-Center Prospective Cohort Study

The current consensus regarding the management of open fracture indicates that the initial debridement should be performed within the first 6 hours after injury. Unfortunately, in Pakistan, the emergency medical services are not well-established and patient arrival at the hospital is delayed the majority of the time. In this study, we present our experience with delayed surgical management of open tibial fractures.

Use of social media while driving from an orthopedic resident's perspective

PURPOSE

To investigate the orthopedic injuries sustained while driving and using social media on cellular phones from an orthopedic resident's perspective.

METHODS

A total of 118 patients who presented with a history of road traffic accident secondary to social media usage and suffered from fractures were included in this cross-sectional study. These patients were reported from October 2018 to April 2019. We collected the data including the type of collision, type of social media usage during driving, location of injury, wearing of safety equipment's such as helmet and seat belt during driving.

RESULTS

The mean age of patients was (34.86 ± 12.73) (range 15-71) years. The common types of accident on the basis of collision of vehicles were: car versus motorbike 45 (38.1%), motorbike versus motorbike 28 (23.7%), and motorbike versus pedestrian 22 (18.6%). Most of the accidents (61, 51.7%) occurred due to mistake of motor-bikers. Out of them, 44 (37.3%) occurred on traffic signals, followed by 29 (24.6%) while driving on main roads. The common timing of accident was normal hours with frequency of 44 (37.3%), followed by 39 (33.1%) at late night. According to fracture type, closed injuries were 98 (83.1%) and open fractures were 20 (16.9%). The most common fracture was clavicular fracture (21, 22.5%) followed by soft tissue injury in 19 (16.1%) patients. The most common social media application usage during driving was Facebook 43 (36.4%), followed by Whatsapp 24 (20.3%), Google 19 (16.1%), and Instagram 15 (12.7%).

CONCLUSION

This study provides evidence that social media usage while driving put the drivers and other road users' lives at high risk. The most common social media addiction while driving is Facebook and Whatsapp. So there is a need to make strict rules and penalties for using cell phone during driving so as to save the lives of drivers and other people using road.

Fixation of distal radius fractures using wide-awake local anaesthesia with no tourniquet (WALANT) technique: A randomized control trial of a cost-effective and resource-friendly procedure

Aims

We hypothesized that the wide-awake local anaesthesia with no tourniquet (WALANT) technique is cost-effective, easy to use, safe, and reproducible, with a low learning curve towards mastery, having a high patient satisfaction rate. Furthermore, WALANT would be a suitable alternative for the austere and developing nation environments where lack of funds and resources are a common issue.

Methods

This was a randomized control trial of 169 patients who required surgery for closed isolated distal radius fractures. The study was performed between March 2016 and April 2019 at a public sector level 1 trauma centre. General anaesthesia was used in 56 patients, Bier’s block in 58 patients, and WALANT in 55 patients. Data were collected on pre-, peri-, and postoperative parameters, clinical outcome, hospital costs, and patient satisfaction. One-way analysis of variance (ANOVA) was used with a p-value of 0.05 being significant.

Results

Operations with WALANT proceeded sooner, and patients recovered faster, resulting in mean fewer missed working days (7.8 (SD 1.67)) compared with general anaesthesia (20.1 (SD 7.37)) or Bier’s block (14.1 (SD 7.65)) (p < 0.001). The WALANT patients did not develop complications, while the other patients did (p < 0.04). Clinical outcomes did not differ, nor did surgeon qualification affect clinical outcomes. Mean hospital costs were lower for WALANT ($428.50 (SD 77.71)) than for general anaesthesia ($630.63 (SD 114.77)) or Bier’s block ($734.00 (SD 37.54)) (p < 0.001). Patient satisfaction was also higher (p < 0.001).

Conclusion

WALANT for distal radius fractures results in a faster recovery, is more cost-effective, has similar clinical outcomes, and has fewer complications than general anaesthesia or Bier's block. This makes WALANT an attractive technique in any setting, but especially in middle- and low-income countries.

The Phenomenon of "Obesity Paradox" in Neck of Femur Fractures

Objective

To determine the association of body mass index (BMI) with 30 days and 1-year mortality outcomes of orthopedic elderly patients after hip fracture surgery.

Methods

This is prospective study conducted at Department of Orthopaedics, at a tertiary care public sector hospital in Karachi between Jan-2016 to Jan-2018. In this short follow-up study, we included the data of 490 patients, who were operated for neck of femur fractures in a public sector tertiary care hospital between Jan-2016 to Jan-2018. Patients were divided into different categories on the basis of BMI; BMI <20 Kg.m^-2 underweight, 20-24.99 Kg.m^-2 normal weight, BMI 25-29.99 Kg.m^-2 overweight, ≥30 obese. Mortality at 30 days and 1-year mortality were primary study end-points.

Results

Rate of re-admission within 30 days, major adverse cardiovascular events (MACE) within 30 days and 30 days mortality was high in underweight and lowest in obese patients. Thirty-day mortality rate was 2.7% in underweight, 1.3% in normal weight, 0.64% in over-weight and 0.0% in obese patients but this was not significant statistically (p-value 0.29). One-year mortality rate was significantly high in under-weight patients, 34.2%, 25.9% in normal weight, 21.4% in overweight and only 14.5% in obese patients (p-value 0.009). Age ≥ 65 years (odds ratio 0.40 (0.26-0.63), and ASA III-IV (odds ratio; 0.27 (0.16-0.45) are also significant risk factors of 1-year mortality.

Conclusion

BMI classification can serve as an important indicator of adverse early outcomes after hip fracture surgery. Over-weight and obese patients have better survival outcomes and have lower 1-year mortality rate.

Transcervical superior wedge resection (osteotomy) and fixation with contoured plate for the non- union of femoral neck fractures

Study was conducted to determine the healing rate of non-union femoral neck fractures following a new transcervical superior based wedge resection and fixation with contoured plate. This study is based on a concept, that the presence of a residual part of the femoral neck on the trochanteric side of the non-union and removal of a wedge with a superior base not only converts shearing forces into compression forces but also provides fresh bone with an osteogenic potential. This is a descriptive case series 'one group pre-test post-test design', conducted from 2010 to 2016 with a sample size of 18, convenience sampling technique with a minimum follow up of 12 months. Eighteen patients with a mean age of 32.44±8.8 years were operated with transcervical wedge resection and fixation. However, only 14 completed a minimum follow up of twelve months. Thirteen (93%) patients achieved union while, one had stable fibrous union which later on developed avascular necrosis and underwent a total hip replacement. There was a mean shortening of 2.05±0.4 cm. Seven (50%) had post-operative Lurch and 4 (28.6%) required shoe raise while 1 had low grade infection.

Comparison of Postoperative Outcomes Between Open Reduction and Internal Fixation and Ilizarov for Schatzker Type V and Type VI Fractures

Introduction

Open reduction and internal fixation (ORIF), hybrid fixation, and external fixation are available treatment options for bicondylar fractures of the proximal tibia but which one is superior to the others is not yet established. Therefore, the study aimed to establish a gold standard treatment option for bicondylar fractures by comparing the clinical, functional, and radiological outcomes managed by Ilizarov and ORIF at 24 months.

Methods

This was a retrospective study conducted from 2009 to 2014 at a public sector, tertiary care, level I trauma center. Patients with Schatzker type V and type VI open and closed fractures were included. Floating knee, pathological fractures of the tibia, and patients having medical conditions were excluded from the study. Honkonen and Jarvinen (HJ) criteria for subjective, clinical, radiological, and functional outcomes were used to compare between the two groups at 24 months. Demographic data included age, gender, Schatzker type, mechanism of injury, and range of knee flexion. Chi-square was used to find the level of significance, which was 0.05.

Results

A total of 137 patients were included in this study, with 68 patients in the ORIF group and 69 in the Ilizarov group during the study period. The mean age of the patients was 45.08 ± 10.52, respectively. The male to female distribution was 107/30 (78.1% and 21.89%). According to the mechanism of injury, road traffic accidents (RTA) were the primary cause of injury: 96 (70.07%), falls were 21 (15.32%), and gunshots were 18 (13.13%). Seventy-four were Schatzker type VI (54.01%) whereas 63 (45.98) were Shcatzker V. The average knee flexion at 24 months was 115.51 ± 16.82. There were no differences in the clinical, functional, and radiological outcomes at 24 months between the two treatment groups.

Conclusion

No single treatment option can be applied in all cases, and the decision depends on the complexity of the injury, the surgeon’s expertise, and host factors.

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.

Malignant fibrous histiocytoma: vascular invasion and metastasis to heart

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.
