Nonunions occur in situations with interrupted fracture healing process and indicate conditions where the fracture has no potential to heal without further intervention. Per definition, no healing is detected nine months post operation and there is no visible progress of healing over the last three months. The classification of nonunions as hypertrophic, oligotrophic, atrophic and pseudoarthosis, as well as aseptic or septic, identifies mechanical and biological requirements for fracture healing that have not been met. The overall treatment strategy comprises identification and elimination of the problems. However, current clinical methods to determine the state of healing are based on highly subjective radiographic evaluation or
In absence of available quantitative measures, the assessment of fracture healing based on
Magnetic resonance imaging (MRI) is the gold standard for the diagnosis of the pathologies affecting the glenohumeral joint and the rotator cuff diseases. MRI allows to highlight anatomic discontinuities of both muscles and tendons. However, MRI diagnostic accuracy has not proven to be highly sensitive in distinguishing between a partial-thickness tear and a full-thickness rotator cuff tear. The purpose of this study was to determine if MRI under axial traction can be helpful in increasing MRI sensitivity to identify partial-thickness rotator cuff tears. The study included 10 patients (4 males and 6 females) who had
Rotator cuff repair has excellent clinical outcomes but continues to be a challenge when it comes to large and massive tears as well as revision procedures. Reported symptomatic retear rates are still too high to be acceptable. The purpose of the present study was to evaluate the effectiveness of a combination of augmentation techniques consisting of microfractures of the greater tuberosity, extracellular matrix (ECM) patch graft and subsequent platelet concentrate (PC) subacromial injections in revision rotator cuff repair. The study was designed as a retrospective comparative study on prospectively collected data from a consecutive cohort of patients. All patients who underwent arthroscopic revision rotator cuff repair for symptomatic failure of previous posterosuperior rotator cuff repair were considered eligible for the study. Symptomatic failure had been diagnosed according to
Barriers to successful return to previous level of activity following Anterior Cruciate Ligament Recon-struction (ACLR) are multifactorial and recent research suggests that athletic performance deficits persist after completion of the rehabilitation course in a large percentage of patients. Thirty soccer athletes (26.9 ± 5.7 years old, male) with ACL injury were surgically treated with all-inside technique and semitendi-nosus tendon autograft. At 2 years from surgery, they were called back for
Introduction and Objective. The surgical strategy for acetabular component revision is determined by available host bone stock. Acetabular bone deficiencies vary from cavitary or segmental defects to complete discontinuity. For segmental acetabular defects with more than 50% of the graft supporting the cup it is recommended the application of reinforcement ring or ilioischial antiprotrusio devices. Acetabular reconstruction with the use of the antiprotrusion cage (APC) and allografts represents a reliable procedure to manage severe periprosthetic deficiencies with highly successful long-term outcomes in revision arthroplasty. Objective. We present our experience, results, critical issues and technical innovations aimed at improving survival rates of antiprotrusio cages. Materials and Methods. From 2004 to 2019 we performed 69 revisions of the acetabulum using defrosted morcellized bone graft and the Burch Schneider anti-protrusion cage. The approach was direct lateral in 25 cases, direct anterior in 44. Patients were re-evaluated with standard radiography and
Lisfranc injuries are uncommon and can be challenging to manage. There is considerable variation in opinion regarding the mode of operative treatment of these injuries, with some studies preferring primary arthrodesis over traditional open reduction and internal fixation (ORIF). We aim to assess the clinical and radiological outcomes of the patients treated with ORIF in our unit. This is a retrospective study, in which all 27 consecutive patients treated with ORIF between June 2013 and October 2018 by one surgeon were included with an average follow-up of 2.4 years. All patients underwent ORIF with joint-sparing surgery by a dorsal bridging plate (DBP) for the second and third tarsometatarsal (TMT) joint, and the first TMT joint was fixed with trans-articular screws. Patients had
The ankle radiograph is a commonly requested investigation as the ankle joint is commonly injured. Each radiograph exposes 0.01 mSv of radiation to the patient that is equivalent to 1.5 days of natural background radiation [1]. The aim of the clinical audit was to use the Ottawa Ankle Rule to attempt to reduce the number of ankle radiographs taken in patients with acute ankle injuries and hence reduce the dose of ionising radiation the patient receives. A retrospective audit was undertaken. 123 ankle radiograph requests and radiographs taken between May and July 2018 were evaluated. Each ankle radiograph request including patient history and
Purpose. Ultrasound of the neonatal and infantile hip is a useful tool in diagnosis and treatment of the developmental dysplasia of the hip (DDH), especially given the fact that numerous cases of DDH do not present any findings in the
Adductor strain is a common injury among football players. The adductor muscle group contains the three adductor muscles. (adductor longus, magnus and brevis) Adductor longus muscle is a triangular-shaped long muscle. This muscle originates from the superior ramus of the pubic bone and inserted into the middle part of the linea aspera. Adductor longus muscle is the most commonly injured muscle of adductors. Sudden acceleration, jumping, stretching, and kicking the ball are common causes of an adductor injury. Adductor muscle strains can result in missed playing time for football players. We present a 26-year-old man soccer player with pain in the left groin and proximal thigh. The symptoms had started during training and after kicking the ball with left foot (dominant side), he felt an acute pain in the groin region and proximal thigh. Despite the injury, he managed to finish the training. The team physician examined the patient immediately after training. The range of motion of both hip joints was in normal ranges and mild pain with adduction. There was a palpable mass at the inner proximal thigh during contraction of adductor muscles. There was no history of groin pain or adductor problems before this injury. Conventional radiographs showed no osseous abnormalities. 36 hours after the injury, MRI revealed acute grade IIB strain in the left adductor longus muscle, including both superior and inferior parts of the muscle. A hematoma was observed in the superior part of the left adductor muscle, with a craniocaudal length of 42 millimeters. There was an adductor muscle strain with hyperintensity extending for a craniocaudal length of approximately 12 centimeters involving more than 50% crosses sectional diameter of the muscle belly. Conservative treatment started immediately, consisting of cold therapy and soft tissue massage. Compression of the injured tissue using a 15-cm elastic bandage roll is done to limit bleeding and provide support. Iced water machine (Game Ready) was used. The team physician examined the player every day and prescribed physiotherapy protocol daily. Additionally, short interval follow-up MRI is used to evaluate the injury. (After 7 and 14 days of the injury) No injection was performed. The player is able to return to play immediately, despite MRI's strain images. The player started straight running 5 days later and joined to team training 8 days later and played 90 minutes-league-match 12 days after injury without any pain. No injection was performed. The player is able to return to play immediately, despite MRI's strain images. The player started straight running 5 days later and joined to team training 8 days later and played 90 minutes-league-match 12 days after injury without any pain. MRI is a useful technique in diagnosing trauma in football players presenting with groin pain. In this case, to estimate time-to-return-to-play, MRI alone is not strong evidence. MRI is a good option for follow up, but anamnesis and
Differences at motor control strategies to provide dynamic balance in various tasks in diabetic polyneuropatic (DPN) patients due to losing the lower extremity somatosensory information were reported in the literature. It has been stated that dynamics of center of mass (CoM) is controlled by center of pressure (CoP) during human upright standing and active daily movements. Indeed analyzing kinematic trajectories of joints unveil motor control strategies stabilizing CoM. Nevertheless, we hypothesized that imbalance disorders/CoM destabilization observed at DPN patients due to lack of tactile information about the base of support cannot be explained only by looking at joint kinematics, rather functional foot usage is proposed to be an important counterpart at controlling CoM. In this study, we included 14 DPN patients, who are diagnosed through
Aim. The knee radiograph is a commonly requested investigation as the knee joint is commonly injured. Each radiograph exposes 0.01mSv of radiation to the patient that is equivalent to 1.5 days of natural background radiation. Also, each knee radiograph costs approximately £37.16 to produce. The aim of the clinical audit was to use the Pittsburgh knee rules to attempt to reduce the number of knee radiographs taken in patients with acute knee injuries and hence reduce the dose of ionising radiation the patient receives. Method. A retrospective audit was undertaken. 149 knee requests and radiographs taken during October 2016 were evaluated. Each knee radiograph request including patient history and
Background. We herein report a case of isolated hip pain in a four year old boy. The unique aspect of this case study is the unusual history, presentation, ultrasonography, MRI and blood culture results, which lead to the diagnosis and treatment of adductor pyomyositis with a rare organism (Streptococcus Mitis) in a temperate country. The objectives of this case study is to discuss the key learning outcomes with respect to assessment and management of this case. Methods. The patient presented with a one day history of malaise, fever, left groin pain and inability to weight bear on the left leg. There was no history of any trauma, predisposing infections or recent travel. A working diagnosis of transient synovitis / septic arthritis of the hip was made on
Background. Patients with hand injuries frequently present to Emergency Departments. The ability of junior doctors to perform an accurate clinical assessment is crucial in initiating appropriate management. Objectives. To assess the adequacy of junior doctor hand examination skills and to establish whether further training and education is required. Methods. A double-centre study was conducted using an anonymous survey assessing hand examination completed by junior doctors (Foundation year 1 and Senior House Officer grades) working in Trauma & Orthopaedics or Emergency Departments. The survey covered all aspects of hand examination including assessment of: Flexor and Extensor tendons, Nerves (motor and sensory) and Vascular status. Surveys were marked against answers pre-agreed with a Consultant hand surgeon. Results. 32 doctors completed the survey. Tendons: 59% could accurately examine extensor digitorum, 41% extensor pollicis longus, 38% flexor digitorum profundus and 28% flexor digitorum superficialis. Nerves – Motor: 53% could accurately examine the radial nerve, 37% the ulnar nerve, 22% the median nerve and 9% the anterior interosseous nerve. Nerves – Sensory: 88% could accurately examine the radial nerve, 81% the ulnar nerve, 84% the median nerve and 18.8% digital nerves. Vascular: 93% could describe 3 methods of assessing vascularity. Conclusions. Tendon and neurological aspects of hand
The Pivot-shift phenomenon (PS) is known to be one of the essential signs of functional insufficiency of the anterior cruciate ligament (ACL). To evaluate the dynamic knee laxity is very important to accurately diagnose ACL injury, to assess surgical reconstructive techniques, and to evaluate treatment approaches. However, the pivot-shift test remains a subjective
To report the case of an asymptomatic simultaneous bilateral neck of femur fracture following vitamin D deficiency which was missed, misdiagnosed and treated for coexisting severe bilateral osteoarthritis knee. A male aged 62 years presented with severe osteoarthritis of both knee joints confining him to bed about eight weeks prior to presentation. The patient did not have any complaints pertaining to his hip joints/axial skeleton. Examination of the hip joints revealed only crepitus with absence of straight leg rising. Radiological survey showed bilateral displaced fracture neck of femur. He had elevated serum alkaline phosphatase; 119IU/L(N:39–117IU/L), decreased Serum 25 (OH) Vit D level;6.03ng/ml(N:7.6–75ng/ml), decreased spot urinary calcium;78mg/day(N:100–300mg/day) with normal serum calcium, phosphorus and highly raised parathormone levels;142.51pg/ml(N:12–72pg/ml). Tc-99 Bone scan showed increased radiotracer uptake in both the hip joints and knee joints. Bone Mineral Density was in favour of osteoporosis. Biopsy fromthe heads of both femurs also revealed osteoporosis. Bilateral staged total hip arthroplasty was done and he was put on Vitamin D replacement therapy. Patient was on regular monthly follow-up for intial one year and three monthly follow-up thereafter. At present with three year follow-up patient is community ambulant with a walking frame. Despite medical advice patient had denied total knee arthroplasty for osteoarthritis of his knee joints. Asymptomatic simultaneous bilateral neck of femur fracture is a rare injury and poses a diagnostic challenge to the treating orthopaedic surgeon with its bizarre clinical picture. Similar presentation of metabolic bone disease can be easily missed without a proper screening, keeping in mind a high index of suspicion for the above disorders. Besides proper
Increase in heel height increases peak pressure under the forefoot. Customized shoe inlays with metatarsal lift, arch support has demonstrated lowered forefoot pressure and increase in the subjective comfort. A commercial shoe brand (Roccamore) has introduced an off-the-rack stiletto with a slim (1 cm. 2. ) 8 cm heel plus 2 cm platform with metatarsal lift, arch support and heel cap claiming it will reduce the discomfort associated with high heels. The primary aim of this study was to compare the pressure under the forefoot, arch, heel and toes in this “orthopaedic” stiletto (OS) to a standard stiletto of the same heel height without inlays (SS) and a control sneaker (SN). Secondary aims were to measure the comfort under the forefoot, heel and arch during everyday use. Finally to investigate if any pressure measurements were correlated to comfort or any anatomical/clinical feature of the foot. 22 women, aged 40 (21–62), accustomed to stilettos, walked at 4 km/hr on a level treadmill in all three shoe types. Peak pressure (kPa) and pressure-time integral (kPa/sec) under 2+3rd and first metatarsal heads, the arch/midfoot and heel were measured during 10 consecutive steps at 50 Hz using Novel Pedar-X pressure distribution insoles. Standing X-rays and a standardized
The purpose of this study was to provide an anatomical explanation for the presence of medial proximal tibial pain in patients with patellar mal-tracking without identifiable medial tibio-femoral compartment or proximal tibial pathology. Using cadaveric dissection we were consistently able to identify a connection between the medial patella and the medial proximal tibia including the medial hamstrings and the posterior oblique expansion. This connection is independent of the inferior patello-tibial ligament and has not previously been described in either anatomical or orthopaedic literature. The dimensions of this medial patello-tibial connection were measured using a digital microscribe. This technique also facilitated the creation of a three dimensional virtual representation of the patello-tibial connection. In the clinical setting, patients presenting with medial proximal tibial pain who had patellar mal-tracking as identified by
Total knee replacement in a commonly performed procedure in the United Kingdom with more than 76000 primary procedures performed in 2010. With so many procedures performed there has to be a robust way of assessing the outcome of the procedure. Gait analysis is a valuable tool in objectively assessing the these patients. Inertial movement units (IMU's) are a fairly new development in gait analysis. The aim of our project is to use IMUs to assess the differences in gait profile between a cohort of healthy controls, a group of pre operative knee replacement patients, a group of 8 week post operative patients and finally a group of post operative knee replacement patients at 1 year. We studied a total of 47 patients. We also had data from a previous study done on healthy controls using the same measurement tool. We measured three parameters: peak swing phase flexion, peak stance phase flexion and stride duration. Our findings indicate that pre-operative patients have a significantly reduced peak flexion in swing and stance with increased stride duration. This shows no improvement at the 8 week mark. At the 1 year mark peak flexion in swing returns to pre operative levels but flexion in stance and stride duration are still poor. These findings may not have been identified without gait analysis. Gait analysis using intertial movement units will add much information to radiographs and
Summary. In the sample studied, reparability of large and massive tears was associated with pre-op ASES and active external rotation in neutral position. Surgical factors affecting reparability were tear size, tendon mobility and shape of the tear. Introduction. The limited literature has shown good results with partial repairs of large and massive tears of rotator cuff but the role of factors that affect reparability is less clear. 1–3. The purpose of this study was twofold, 1) to explore the predictive value of clinical and surgical factors on reparability of large and massive rotator cuff tears and 2) to examine the relationship between reparability and clinical and disability measures. Patients and Methods. This was a secondary data analysis of consecutive patients with large or massive rotator cuff tear who required surgical treatment (full or partial repair) and had returned for their two year follow-up. Disability measures included the American Shoulder and Elbow Surgeons (ASES), the relative Constant-Murley score (RCMS) and the shortened version of the Western Ontario Rotator Cuff Index (ShortWORC). The relationship between predictors and reparability was examined through logistic regression and chi-square statistics as appropriate. Within group change over time and between group differences in disability outcomes, range of motion and strength were examined by student's T-tests and non-parametric statistics. Results. One hundred and fourteen patients (40 women, mean age 64, SD=9) were included in the analysis. There were 79 large (34 fully reparable, 45 partially reparable) and 35 (10 fully reparable, 25 partially reparable) massive tears. Reparability was not associated with age, sex, or pre-operative active flexion or abduction (p>0.05) but the fully repairable tear group showed a better pre-operative ASES score (p=0.01) and a better active external rotation in neutral (p=0.05). Reparability was associated with tear shape (p<0.0001) and size (p=0.007), and tendon mobility (p<0.0001). Discussion/Conclusion. Among demographics,
