The Nottingham Hip Fracture
Osteoporosis is a common disorder characterized by low bone mass and reduced bone quality that affects the bone strength negatively and leads to increased risk of fracture. Bone mineral density (BMD) has been the standard instrument for the diagnosis of osteoporosis and the determination of fracture risk. Despite the approximation of the bone mass, BMD does not provide information about the bone structure. Trabecular bone
The regenerative potential of bone is enormous, and it is possible to lengthen limbs by bone distraction. However, there remains a major risk of fracture after lengthening the bone. Previous studies have described how the pixel value ratio may be used for determining the time for frame removal. The aim of this study was to investigate the intrarater and the interrater reliability of pixel value

There are many factors which contribute to function after TKA. In this study we focus on the effect of varus-valgus (VV) balancing measured externally. A loose knee can show instability (Sharkey 2014) while too tight, flexion can be limited. Equal lateral-medial balancing at surgery leads to a better result (Unitt 2008; Gustke 2014), which is generally the surgical goal. Indeed similar varus and valgus laxity angles have been found in most studies in vitro (Markolf 2015; Boguszewski 2015) and in vivo (Schultz 2007; Clarke 2016; Heesterbeek 2008). The angular ranges have been 3–5 degrees at 10–15 Nm of knee moment, females having the higher angles. The goal of this study was to measure the varus and valgus laxity, as well as the functional outcome scores, of two cohorts; well-functioning total knees after at least one year follow-up, and subjects with healthy knees in a similar age group to the TKR's. Our hypothesis was that the results will be equal in the two groups. 50 normal subjects average age 66 (27 male, 23 female) and 50 TKA at 1 year follow-up minimum average age 68 years (16 male, 34 female) were recruited in this IRB study. The TKA's were performed by one surgeon (PAM) of one TKA design, balancing by gap equalization. Subjects completed a KSS evaluation form to determine functional, objective, and satisfaction

A major cause of morbidity in lower limb amputees is phantom limb pain (PLP) and residual limb pain (RLP). This study aimed to determine if surgical interposition of nerve endings into adjacent muscle bellies at the time of major lower limb amputation can decrease the incidence and severity of PLP and RLP. Data was retrospectively collected from January 2015 to January 2021, including eight patients that underwent nerve interposition (NI) and 36 that received standard treatment. Primary outcomes included the 11-point Numerical Rating Scale (NRS) for pain severity, and Patient-Reported Outcomes Measurement Information System (PROMIS) pain intensity, behaviour, and interference. Secondary outcome included Neuro-QoL Lower Extremity Function assessing mobility. Cumulative
Abstract. Cranial cruciate ligament (CrCL) disease/rupture is a highly prevalent orthopaedic disease in dogs and common cause of pain, lameness, and secondary joint osteoarthritis (OA). Previous experiments investigating the role of glutamate receptors (GluR) in arthritic degeneration and pain revealed that OA biomarkers assessing early bone turnover and inflammation, including osteoprotegerin (OPG) and the receptor activator of nuclear factor kappa-B ligand (RANKL) are more likely to be influenced by glutamate signalling. Moreover, interleukin-6 (IL-6) has a complex and potentially bi directional (beneficial and detrimental) effect, and it is a critical mediator of arthritic pain, OA progression and joint destruction. Objectives. 1) to recruit dogs undergoing CrCL disease/rupture surgery and obtain discarded synovial fluid (SF) and serum/plasma (ethics approval, RCVS:2017/14/Alves); 2) to quantify the biomarkers listed above in the SF and serum/plasma by enzyme linked immunosorbent assay (ELISA); 3) to assess radiographic OA at the time of surgery and correlate it with the biomarkers and clinical findings. Methods. Abnova, Abcam and AMSBIO ELISA kits were tested using a validation protocol relating the standard curve to a dilution series of SF and serum/plasma (1× to 1/50×), with and without SF hyaluronidase treatment to evaluate linearity, specificity and optimal dilutions. Validated ELISA kits were used to measure [IL-6], glutamate [glu], [RANKL] and [OPG] in SF and serum/plasma. For each dog, CrCL disease pre-operative lameness

Cannulated hip screws are frequently used in the management of hip fractures. There have been concerns over the failure rate of the technique and the outcomes of those that subsequently require conversion to total hip replacement (THR). This study utilised a database of over 600 cannulated hip screw (CHS) fixations performed over a 14-year period and followed up for a minimum of one year (1-14). We identified 57 cases where a conversion to THR took place (40 females, 17 males, mean age: 71.2 years). Patient demographics, original mechanism of injury, fracture classification, reason for fixation failure, time until arthroplasty, implant type and post-arthroplasty complications were recorded. Clinical outcomes were measured using the Oxford Hip
To evaluate the therapeutic effect of Pulsed Electromagnetic Field (PEMF) in the treatment of meniscal tears in the avascular region. Seventy-two twelve-week-old male Sprague-Dawley rats with full-thickness longitudinal medial meniscal tears in the avascular region were divided into 3 groups: control group (G. con. ), treated with classic signal PEMF (G. classic. ), and high slew rate signal PEMF(G. HSR. ). The HSR signal has the same pulse and burst frequencies as the classic signal, but with a higher slew rate. Macroscopic observation and histological analysis of the meniscus and articular cartilage were performed to evaluate the meniscal healing and progressions of osteoarthritis. The synovium was harvested for histological and immunofluorescent analysis to assess the intra-articular inflammation. The meniscal healing, articular cartilage degeneration, and synovitis were quantitatively evaluated according to their respective
The purpose of this study is to report the clinical and radiological outcomes of patients undergoing primary or revision reverse total shoulder arthroplasty using custom 3D printed components to manage severe glenoid bone loss with a minimum of 2-year follow-up. After ethical approval (reference: 17/YH/0318), patients were identified and invited to participate in this observational study. Inclusion criteria included: 1) severe glenoid bone loss necessitating the need for custom implants; 2) patients with definitive glenoid and humeral components implanted more than 2 years prior; 3) ability to comply with patient reported outcome questionnaires. After seeking consent, included patients underwent clinical assessment utilising the Oxford Shoulder
