Intraoperative fractures although rare are one of the complications known to occur while performing a total hip arthroplasty (THA). However, due to lower incidence rates there is currently a gap in this area of literature that systematically reviews this important issue of complications associated with THA. Method: We looked into Electronic databases including PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), the archives of meetings of orthopaedic associations and the bibliographies of included articles and asked experts to identify prospective studies, published in any language that evaluated intra-operative fractures occurring during total hip arthroplasty from the year 1950-2020. The screening, data extraction and quality assessment were carried out by two researchers and if there was any discrepancy, a third reviewer was involved. Fourteen studies were identified. The reported range of occurrence of fracture while performing hip replacement surgery was found to be 0.4-7.6%. Major risk factors identified were surgical approaches, Elderly age, less Metaphyseal-Diaphyseal Index score, change in resistance while insertion of the femur implants, inexperienced surgeons, uncemented femoral components, use of monoblock elliptical components, implantation of the acetabular components, patients with ankylosing spondylitis, female gender, uncemented stems in patients with abnormal proximal femoral anatomy and with cortices, different stem designs, heterogeneous fracture patterns and toothed design. Intraoperative fractures during THA were managed with cerclage wire, femoral revision, intramedullary nail and cerclage wires, use of internal fixation plates and screws for management of intra operative femur and acetabular fractures. The main reason for intraoperative fracture was found to be usage of cementless implants but planning and timely recognition of risk factors and evaluating them is important in management of intraoperative fractures. Adequate surgical site exposure is critical especially during dislocation of hip, reaming of acetabulum, impaction of implant and preparing the femoral canal for stem insertion. Eccentric and increased reaming of acetabulum to accommodate a larger cup is to be avoided, especially in females and elderly patients as the acetabulum is thinner. However, this area requires more research in order to obtain more evidence on effectiveness, safety and management of intraoperative fractures during THA.
Deep vein thrombosis (DVT) in shoulder operations is rare although a few case reports exist. No definite guidelines exist and therefore it is difficult for the surgeon to decide on thromboprophylaxis. We prospectively evaluated the incidence of DVT following arthroscopic shoulder sub acromial decompression in 72 patients after obtaining local ethics committee approval. Patients with previous history of DVT and those on anticoagulants were excluded from the study. Pre and post-operative Doppler scans on 4 limbs were performed by a single consultant radiologist at an average of 3 weeks. All operations were performed by a single surgeon under GA in beach chair position as a day case procedure on standard lines. Postoperatively the shoulder was immobilised in a sling for comfort and physiotherapy was supervised by a qualified therapist. No patient received any DVT prophylaxis. The average age of 54.6 years, 47 were classified as ASA 1, 15 as ASA 2 and 10 ASA 3.58 patients had additional interscalene nerve blocks for pain relief. The average operating time was 43 mins. Additional procedures included excision of lateral clavicle in 32, glenoid labral and rotator cuff debridement in 12 and 14 patients. There were no DVTs on Doppler scans. Shoulder arthroscopic sub acromial decompression procedures do not carry a risk of DVT and routine thromboprohylaxis is not required even in higher anaesthetic risk patients.
We obtained approval from the local research and ethics committee and prospectively evaluated the incidence of Deep vein thrombosis (DVT) in arthroscopic shoulder sub acromial decompression in 72 patients. All patients were assessed clinically for DVT risks as per the established guidelines. Patients with previous history of DVT, those on anticoagulants and those positive for DVT on pre op scans were excluded from the study. All patients had doppler scans on 4 limbs performed by a single consultant radiologist at an average of 4 weeks pre and post operative period. All operations were performed by a single surgeon under GA in beach chair position with routine precautions for DVT, as a day case procedure. Arthroscopy and additional procedures were performed on standard lines. Postoperatively the shoulder was immobilised in a sling for comfort and physiotherapy was supervised by a qualified therapist. Demographic data, co-morbidities, patient position, ASA risk, nerve blocks, surgery duration, medications, intra operative findings, were documented. No patient received any DVT prophylaxis. All patients were available for followup and clinical and doppler findings were documented at an average 4 week period. 3 patients had bilateral procedures. There were 38 female and 34 male patients with an average age of 54.6 years. 47 were classified as ASA1, 15 as ASA2 and 10 ASA 3. Common co morbidities included hypertension, diabetes, acid peptic disease in 34 patients. 37 patients had additional interscalene nerve blocks for pain relief. The average operating time was 52 mins. Additional procedures included excision of lateral clavicle in 32, glenoid labral and rotator cuff debridement in 12 and 14 patients. There were no DVT's on all doppler scans. Shoulder arthroscopic sub acromial decompression procedures do not carry a risk of DVT and routine thromboprohylaxis is not required even in higher anaesthetic risk patients.
