Background Epidemiological studies on the prevalence and management of chronic low back pain (CLBP), osteoarthritis (OA), and diabetic peripheral neuropathy (DPN) are limited in Egypt. This review aimed to map and identify data gaps in the patient journey touchpoints for CLBP, OA, and DPN. Main body of the abstract An evidence-based mapping approach using MEDLINE, Embase, and Biosis databases were used to identify records between January 2010 and December 2019. Quantitative data synthesis was performed using simple mean or weighted mean, whereas qualitative information was synthesized using a narrative summary. For CLBP, of the 79 records retrieved, 11 were eligible for final analysis (7 CLBP and 4 OA records), and for DPN, of 42 records identified, 13 studies were eligible. For CLBP, data available for prevalence, awareness, and treatment were 34.3%, 39.5%, and 70.0%, respectively. The prevalence of OA was 43.0%. The majority (98.6%) of patients with OA adhered to the treatment, and in 96.2% of the patients’ symptoms were controlled. The prevalence of DPN was estimated to be 42.7%, synthesized evidence indicated that 14.1% of patients were aware of DPN and 22.7% underwent screening. Conclusion As the existing literature is limited, further evidence-based studies are required to accurately understand the complexity of patient journey touchpoints in Egypt. Although the studies on musculoskeletal chronic pain syndrome are limited, the high prevalence of chronic low back pain, osteoarthritis and peripheral neuropathy should urge the health care system to organize the research groups and health care facilities to focus on these disorders and to consider them in the global health care plans. 

Shoulder pain is a common musculoskeletal complaint, and rotator cuff (RC) pathologies are one of the main causes. The RC undergoes various tendinopathic and avascular changes during the aging process. Other degenerative changes affecting its healing potential make it an appealing target for biological agents. Platelet-rich plasma (PRP) has demonstrated the potential to deliver a high concentration of several growth factors and anti-inflammatory mediators, and its clinical use is mainly supported by experiments that demonstrated its positive effect on muscle, ligaments, and tendinous cells. This review aimed to specify the role of PRP and its future applications in RC tendinopathies based on the current clinical evidence. Due to the different characteristics and conflicting outcomes, clinicians should use PRP with moderate expectations until more consistent evidence is available. However, it is reasonable to consider PRP in patients with contraindications to corticosteroid injections or those with risk factors for inadequate healing. Its autologous origin makes it a safe treatment, and its characteristics make it a promising option for treating RC tendinopathy, but the efficacy has yet to be established. 

Introduction: Non-autoimmune sacroiliac joint pain contributes to nearly a quarter of low back pain patients. Non-surgical management fails to satisfy patients. A new minimally invasive technique for sacroiliac stabilization has been introduced, defying the traditional rules of fusion. The results outside explanatory trials and in day-to-day practice have not been reported. Materials and methods: This case series includes 20 patients diagnosed with chronic sacroiliac pain resistant to conservative management for at least 6 months. The diagnosis was confirmed with a positive sacroiliac injection. Patients underwent stabilization using the iFuse® implant. Patients were followed up for a minimum of one year. The primary outcome was the functional outcomes, assessed using VAS, ODI, and SF36. Secondary procedure rates, complication rates, and radiological assessments of fusion were collected as secondary outcomes. Results: At one year, the mean VAS score improved from 81.25 ± 10.7 SD preoperatively to 52.5 ± 26.8, p-value 0.0013. The mean ODI improved from 54.8 ± 11.21 SD preoperatively to 41.315 ± 15.34, P value = 0.0079. The mean PCS and MCS of SF36 improved by 17 and 20 points, respectively. Only 55% of patients achieved the MCID for the VAS score. 35% of the cohort had secondary procedures. Discussion: Minimally invasive sacroiliac fusion resulted in an improvement in mean functional scores with a wide dispersion. Patients not achieving MCID are patients with either a malpositioned implant, an associated lumbar pathology, or an inaccurate diagnosis. Our results are underwhelming compared to similar work but are still better than conservative cohorts in comparative studies. Conclusion: Minimally invasive sacroiliac fusion can be used successfully in select patients. Attention to diagnosis and surgical technique can improve the reproducibility of results. 

Abstract Introduction Biomechanical studies have compared fixation methods in transverse acetabular fractures, yet there is not enough clinical data to suggest an optimal fixation method. The aim of this randomized controlled trail was to compare fracture stability in posterior plating alone versus posterior plating and anterior column lag-screw fixation in treatment of transverse and transverse with posterior wall acetabular fractures. Methods Thirty patients were randomized to one of two groups, either posterior fixation alone (single column group), or posterior plating and anterior fixation with percutaneous anterior column screw (double column group). Patients were followed up with serial radiographic assessments documenting any loss of reduction, utilizing Matta’s radiological criteria, measuring the roof arc angles and by measuring any change in the femoral head offset. Results Fifteen patients were randomized to each group. Mean patient age was 31 years, mean follow up period was 19 months (range 12-24). There was no significant differences between the two groups with regards the quality of post-operative reduction, blood loss, hospital stay and functional score using the modified Merle D'Aubinge and Postel score. The operative time was significantly longer in the double column fixation group (130 minutes versus 104 minutes). There was no loss of reduction observed in either of the two groups. Conclusion Single poster column fixation in transverse and transverse posterior wall fractures showed similar result to double column fixation, in terms of fractures stability in the follow up period, quality of reduction and early functional outcome. 

Purpose Failed internal fixation of intertrochanteric fractures typically leads to profound functional disability and pain. Conversion hip arthroplasty in this situation is technically demanding. The purpose of this study was to evaluate the results, technical problems and complications, as well as the impact, of different factors on such procedure. Patients and methods From May 2009 to October 2011, 30 patients (23 female and seven male) with a mean age of 66 years (range: 50–90 years old) were included in the study. Total hip replacement was used in all cases. Cemented stems were most commonly used because of poor bone quality (standard length in 10, long stems in 14 and calcar replacing in two). Cementless standard length stems were used in four patients. The mean follow-up was 25 months (range: 12–33 months). Results A statistically significant improvement was found comparing preoperative and postoperative conditions (P<0.05). When comparing different factors, the age was the only statistically significant factor affecting the functional outcome, denoting better results with patients younger than 65 years of age (P=0.002). We had four intraoperative fractures, one postoperative fracture, three dislocations, a single case of infection and two cases of implant loosening. Conclusion Although conversion hip arthroplasty is technically demanding, it is associated with a high success rate with good functional outcome and pain relief especially in younger age groups.
 

 Purpose: To study the angle of screw placement in relation to the scaphoid fracture plane and its effect on union after percutaneous fixation of scaphoid waist fractures. Methods: Twenty-four consecutive scaphoid waist fractures were retrospectively evaluated for the orientation of screws in relation to the fracture plane using a method in which the sum-of-smaller angles (SSA) in 3 different radiographs were used to correlate with time to fracture union. Results: All but one patient achieved union after percutaneous fixation of the scaphoid. Another patient required revision surgery within the study period for inadequate fixation. A shortened time to union was significantly correlated to larger SSA. Conclusions: SSA may be a reasonable predictor of union after percutaneous fixation of scaphoid waist fracture. It can be reliably calculated using plain radiographs. An SSA of 190° or more correlated with union by 8 weeks postoperatively. Type of study/level of evidence: Prognostic IV.
