Abstract. Background. Scaphoid non-union can result in pain, altered wrist kinematics leading to a Scaphoid Non-union Advance Collapse, ultimately to symptomatic radio-carpal arthritis. Open techniques have their limitations. We describe the rationale, surgical technique and outcomes of our series of arthroscopic bone-grafting (ABG) and fixation of scaphoid non-union. Methods. We performed a prospective single-surgeon series of 22 consecutive patients with clinico-radiologically established scaphoid non-union between March 2015 and April 2019. Data was collected from Electronic Patient Records, Patient Archived Computer system (PACS) and hand therapy assessments. We collected demographic data including age, hand-dominance, occupation and mechanism of injury. The Disabilities of the Arm, Shoulder and Hand Score (Quick DASH), Mayo wrist score, Patient Rated Wrist Evaluation (PRWE) and grip-strength measurements were collected preoperatively and at follow-up appointments. Results. There was an improvement in all outcome measures when comparing preoperative and postoperative results. The Quick DASH score improved by a mean of 24 points, Mayo wrist and PRWE scores improved by 15.1 and 29.7 points, respectively. Grip-strength analysis also improved by 6.1 kgf (Right) and 3.3kgf (Left). Follow-up computerised tomography scans revealed union in 18/22 patients with 2 patients lost to follow-up. One patient required revision ABG procedure to achieve union. Conclusion. Arthroscopic

Aim. Bone and implant-associated infections caused by microorganisms that grow in biofilm are difficult to treat because of persistence and recurrence. Systemic administration of antibiotics is often inefficient because the poor vascularization of the site of infection. This issue has led to the development of biomaterials capable to locally deliver high doses of therapeutic agents to the injured bone with minimal systemic effects. In this context, calcium sulphate/hydroxyapatite (CS/HA)
Introduction. Acetabular reconstruction of a total hip arthroplasty (THA) for a case with severe bone loss is most challenging for surgeon. Relatively high rate of failure after the reconstruction surgery have been reported. We have used Kerboull-type acetabular reinforcement devices with morsellised or bulk bone allografts for these cases. The purpose of this study was to examine the midterm results of revision THA using Kerboull-type acetabular reinforcement devices. Patients and methods. We retrospectively reviewed 20 hips of revision THA (20 patients) between February 2002 and August 2010. The mean age of the patients at the time of surgery was 67.4 years (range 45–78). All of the cases were female. The mean duration of follow-up was 6.5 years (range 2.1–10.4). The reasons of revision surgeries were aseptic loosening in 10 hips, migration of bipolar hemiarthroplasty in 8 hips, and rheumatoid arthritis in 2 hips. We classified acetabular bone defects according to the American Academy of Orthopaedic Surgeons (AAOS) classification; we found two cases of Type II and eighteen cases of Type III. In terms of
Lateralization of the reverse arthroplasty may be desirable to more effectively tension the remaining rotator cuff, decrease scapular notching, improve the cosmetic appearance of the shoulder, and improve stability as well as the arc of motion prior to impingement. There are two primary options to lateralise a reverse shoulder arthroplasty:
Objectives. Our principle is to bring the socket back to the true acetabulum position. A large structural
Reverse TSA initially followed Grammont's dictum that the center of rotation (COR) must be in the bone (“medial” COR). Others have argued for a more lateral COR, which can be a challenge if glenoid bone stock has been medially eroded. When bone loss must be made up, and/or the COR lateralised, the options include use of
Introduction. Today, Uganda has the second highest rate of road accidents in Africa and the world after Ethiopia. According to the World Health Organization's Global Status Report on Road Safety 2013, Uganda is named among countries with alarmingly high road accident rates. If such trend of traffic accidents continues to increase, the health losses from traffic injuries may be ranked as the second to HIV/AIDS by 2020. These road traffic accidents often result in terrible open injuries. Open fractures are complex injuries of bone and soft tissue. They are orthopedic emergencies due to risk of infection secondary to contamination and compromised soft tissues and sometimes vascular supply and associated healing problems. Any wound occurring on the same limb should be suspected as result of open fracture until proven otherwise. The principles of management of open fracture are initial evaluation and exclusion of life threatening injuries, prevention of infection, healing of fracture and restoration of function to injured extremity. Because of the poor hygienic circumstances and the high rate of cross-infection due to the crowded patient-wards, the risk of getting a post-operative infection is relatively high.

The aim of our study is to investigate the natural history of scaphoid non-union. Factors affecting the outcome of scaphoid fracture non-union surgery were assessed using data collected retrospectively from 785 cases treated at 18 centres throughout the UK. All cases had undergone this surgery before October 2014, ensuring a minimum period of 2 years between surgery and data collection from the medical records. Smoking status significantly influenced the union rate of 94 proximal pole (non-smokers = 71%, smokers = 44%, p < 0.05) but not waist (non-smokers = 73% non-unions. Type of
Scaphoid fractures accounts for approximately 15% of all fractures of hand and wrist. Proximal pole fractures represent 10–20% of scaphoid fractures. Non –operative treatment shows high incidence of non-union and avascular necrosis. Surgical intervention with
Introduction. The natural history of osteonecrosis of the femoral head (ONFH) is not cleanly understood, but most of them progresse to the joint destruction and requires total hip replacement arthroplasty. There are several head preserving procedure, but no single therapeutic method proved to be effective in preventing progression of the disease. The possibility has been raised that implantation of bone marrow containing osteogenic precursors may be effective in the treatment of this disease. However, there are no long-term follow-up results of cell therapy for ONFH. AS far as we know, there are no reports about
