Is Cemented Bipolar Hemiarthroplasty Good Choice For Unstable Intertrochanteric Fractures In Elderly: Multicentric Prospective Study At Karachi.

Background: To analyse the functional outcome of primary cemented bipolar hemi arthroplasty (PCBH) for unstable osteoporotic intertrochanteric femur fractures in elderly patients. Methods: : It was a multicentre prospective study conducted at Institute of Orthopaedics & Surgery, Medicare Cardiac & General Hospital and Dr Ruth K M Pfau Civil Hospital Karachi, Pakistan from February 2015 to July 2020. Thirty-eight patients of 60-90 years of either gender diagnosed as close UIF, severe osteoporosis as per Singh index grade ≤3, time since injury <2 weeks, ASA status II & III and pre-injury independent walking were enrolled in this study. All patients with UIF underwent PCBH. The radiographs were performed before surgery and at intervals postoperatively. All patients were requested to come for follow up visits at 2 weeks, 4 weeks, 3 months, 6 months 1 year and then at 3 years to assess the functional outcome of patients. At first postoperative day check X-rays taken and rehabilitation started as per institutional rehabilitation protocol, at 2-week stiches removed, at 4 weeks' x-ray was done and all the patients were followed for 3 years. The primary outcomes were noted using Harris Hip Score (HHS) for the functional outcome assessed at the end of 1 year and at final follow up. Results: The mean age of the study participants was 68.29±8.04 years. One male (2.6%) died at 6th month, then 2 females (5.2%) patients died at 1 year and 2 females (5.2%) patients died at the end of 3 years due to multiple comorbid conditions. During 1st year 3 patients (7.4%) developed DVT and 4 patients (10.5%) having diabetes and hypertension developed superficial wound infection. The mean Harris Hip Score between time points which indicated that the mean Harris Hip Score significantly improve over the period of time (p=0.001). Post hoc tests revealed that there were statistically significant differences between each time points (p<0.05). The functional outcome at 3 years, shown, one patient had excellent outcome, 24 patients had good outcome and 8 had fair outcome, respectively. Conclusion: The Primary Cemented Bipolar Hemiarthoplasty is a good choice of treatment in terms of reasonable functional outcome such as early mobilization and associated with less post-operative complications in elderly patients of UIF.

Management of the bone loss by metaphyseal sleeves in primary and revision knee arthroplasty: clinical experience and outcome after forty three cases.

AIM OF THE STUDY: Management of metaphyseal bone loss in complex primary and revision TKA is a challenge for surgeons. Out of various types of bony defects, large metaphyseal bone loss (AORI types IIB and III) requires special augments in the form of cones or sleeves. The aim of this study is to assess the reliability of metaphyseal sleeves, in dealing with massive bone defects to provide stability for immediate weight bearing and also to check short to mid-term survivorship of metaphyseal sleeves in Asian population by assessing various parameters and complications. METHODS: This is a retrospective study that includes 36 patients (43 knees), operated from 2011 to 2019. Patients with AORI type IIB (large metaphyseal bone defect) and AORI type III (metaphyseal defect with compromised collateral ligaments) were included. We included both the primary and revision knee arthroplasties in our study. Our interest in this study was to look for incidence of intra-operative iatrogenic fracture on the one hand, and post-operative complications in the form of peri-prosthetic joint infection and aseptic loosening on the other hand. Knee Society Score (KSS) was used to assess improvement in patient's clinical outcome. SPSS version 23 was used to process data. RESULTS: The average age of patients in our study was 59.4 (SD 9.78) years. Male to female ratio was 21:15. The average follow-up was 5.42 (SD 2.24) years with the longest follow up of nine years. Metaphyseal sleeves were used in 12 primary TKA and 31 revision TKA. During surgery, iatrogenic fracture of tibial condyle was encountered in three patients (6.9%), all were managed without any intervention and union was achieved in all cases. There was not a single case with aseptic loosening as per radiological criteria in our study. Peri-prosthetic joint infection (PJI) was encountered in a single case (2.3%). Pre-op Knee Society Score (KSS) was 36.21 (SD 7.43) where as it improved to 92.00 (SD 5.66), six months after surgery. Also the range of flexion was increased from 76.83o (SD 14.07o) to 122.91o (SD 4.84o). CONCLUSION: In our study, metaphyseal sleeves showed excellent short to mid-term survivorship in AORI types IIB and III boneloss in Asian population. These results are comparable to various studies conducted on North American and European population. Metaphyseal sleeve is a reliable tool in the armamentarium of the arthroplasty surgeon. It is user friendly implant and provides immediate stability to allow full weight-bearing mobilization.

"The role and ability of orthopaedic postgraduate resident's clubfoot treatment with ponseti's methodology." A comparative study of resident's versus consultant's directed treatment.

OBJECTIVE: To evaluate the outcome of Ponseti treatment carried out by the Postgraduate Orthopaedic Trainees compared with the treatment given by their Mentors. METHODS: The prospective comparative case series study was conducted at Jinnah Postgraduate Medical Centre, Karachi, and comprised idiopathic Congenital Clubfoot Deformity patients treated from September 2012 to December 2013. Also included were a few cases treated between September 2006 and September 2012, who had complete record, serial photograph and updated follow-up. The patients were divided into two groups. Those treated by residents formed Group A and those by consultants were in Group B. The follow-up duration ranged from 06 months to 05 years. Outcome measures included the number of casts required to achieve correction with Pirani score 0.5, the rate of Per-Cutaneous Achilles Tenotomy (PCAT), the rate of early relapse and treatment and failure to maintain correction. SPSS 13 was used for statistical analysis. RESULTS: Of the 172 patients in the study, 111(64.5%) patients with 185 feet were treated by the residents, while 61(35.5%) patients with 96 feet were treated by consultant. The overall mean age was 25.8±32.88 weeks (range: 1-156 weeks). The difference in age between the two groups was significant (p=0.01). A total of 166(96.51%) patients were on maintenance phase in Foot Abduction Bracing and 6(3.48%) completed the treatment successfully without residual deformity. The median number of cast per patient given by Group A was 6 and 5 in Group B. The number of 8+ casts given in Group A were 46 (24.86%) and 17 (17.7%) in Group B. Tenotomies performed in Group A were 106 (57.27%) and 70 (73%) in Group B, and overall PCAT performed were 183 (65.12%). The overall success rate was nearly similar between the two groups, with the difference of<1%. CONCLUSIONS: The best practice to achieve excellent to good results from the beginners in Ponseti technique is to provide mentorship training for the skill of Ponseti manipulation, application of cast and continued treatment.

Difficulties in maintenance of clubfoot abduction brace and solutions - maintenance of clubfoot abduction brace, locks and keys.

OBJECTIVE: To determine the frequency of early relapse after achieving good initial correction in children who were on clubfoot abduction brace. METHODS: The cross-sectional study was conducted at the Jinnah Postgraduate Medical Centre, Karachi, and included parents of children of either gender in the age range of 6 months to 3years with idiopathic clubfoot deformities who had undergone Ponseti treatment between September 2012 and June 2013, and who were on maintenance brace when the data was collected from December 2013 to March 2014. Parents of patients with follow-up duration in brace less than six months and those with syndromic clubfoot deformity were excluded. The interviews were taken through a purposive designed questionnaire. SPSS 16 was used for data analysis. RESULTS: The study included parents of 120 patients. Of them, 95(79.2%) behaved with good compliance on Denis Browne Splint, 10(8.3%) were fair and 15(12.5%)showed poor compliance. Major reason for poor and non-compliance was unaffordability of time and cost for regular follow-up. Besides, 20(16.67%) had inconsistent use due to delay inre-procurement of Foot Abduction Braceonce the child had outgrown the shoe. Only 4(3.33%) talked of cultural barriers and conflict of interest between the parents. Early relapse was observed in 23(19.16%) patients and 6(5%) of them responded to additional treatment and were put back on brace treatment; 13(10.83%) had minor relapse with forefoot varus, without functional disability, and the remaining 4(3.33%) had major relapse requiring extensive surgery. Overall success was recorded in 116(96.67%) cases. CONCLUSIONS: The positioning of shoes on abduction brace bar, comfort in shoes, affordability, initial and subsequent delay in procurement of new shoes once the child's feet overgrew the shoe, were the four containable factors on the part of Ponseti practitioner.
