Lisfranc injuries were previously described as fracture-dislocations of the tarsometatarsal joints. With advancements in modern imaging, subtle Lisfranc injuries are now more frequently recognized, revealing that their true incidence is much higher than previously thought. Injury patterns can vary widely in severity and anatomy. Early diagnosis and treatment are essential to achieve good outcomes. The original classification systems were anatomy-based, and limited as tools for guiding treatment. The current review, using the best available evidence, instead introduces a stability-based classification system, with weightbearing radiographs and CT serving as key diagnostic tools. Stable injuries generally have good outcomes with nonoperative management, most reliably treated with immobilization and non-weightbearing for six weeks. Displaced or comminuted injuries require surgical intervention, with open reduction and internal fixation (ORIF) being the most common approach, with a consensus towards bridge plating. While ORIF generally achieves satisfactory results, its effectiveness can vary, particularly in high-energy injuries. Primary arthrodesis remains niche for the treatment of acute injuries, but may offer benefits such as lower rates of post-traumatic arthritis and hardware removal. Novel fixation techniques, including suture button fixation, aim to provide flexible stabilization, which theoretically could improve midfoot biomechanics and reduce complications. Early findings suggest promising functional outcomes, but further studies are required to validate this method compared with established techniques. Future research should focus on refining stability-based classification systems, validation of weightbearing CT, improving rehabilitation protocols, and optimizing surgical techniques for various injury patterns to ultimately enhance patient outcomes.

Introduction. Fibula shortening with an intact anterior tibiofibular ligament (ATFL) and medial ligament instability causes lateral translation of the talus. Our hypothesis was that the interaction of the AITFL tubercle of the fibular with the tibial incisura would propagate lateral translation due to the size differential. Aim. To assess what degree of shortening of the fibular would cause the lateral translation of the talus. Methodology. Twelve cadaveric ankle specimens were dissected removing all soft tissue except for ligaments. They were fixed on a specially-designed platform within an augmented ankle cage allowing tibial fixation and free movement of the talus. The fibula was progressively shortened in 5mm increments until
Hip disease is common in children with cerebral palsy (CP) and can decrease quality of life and function. Surveillance programmes exist to improve outcomes by treating hip disease at an early stage using radiological surveillance. However, studies and surveillance programmes report different radiological outcomes, making it difficult to compare. We aimed to identify the most important radiological measurements and develop a core measurement set (CMS) for clinical practice, research, and surveillance programmes. A systematic review identified a list of measurements previously used in studies reporting radiological hip outcomes in children with CP. These measurements informed a two-round Delphi study, conducted among orthopaedic surgeons and specialist physiotherapists. Participants rated each measurement on a nine-point Likert scale (‘not important’ to ‘critically important’). A consensus meeting was held to finalize the CMS.Aims

Early detection of developmental dysplasia of the hip (DDH) is associated with improved outcomes of conservative treatment. Therefore, we aimed to evaluate a novel screening programme that included both the primary risk factors of breech presentation and family history, and the secondary risk factors of oligohydramnios and foot deformities. A five-year prospective registry study investigating every live birth in the study’s catchment area (n = 27,731), all of whom underwent screening for risk factors and examination at the newborn and six- to eight-week neonatal examination and review. DDH was diagnosed using ultrasonography and the Graf classification system, defined as grade IIb or above or rapidly regressing IIa disease (≥4o at four weeks follow-up). Multivariate odds ratios were calculated to establish significant association, and risk differences were calculated to provide quantifiable risk increase with DDH, positive predictive value was used as a measure of predictive efficacy. The cost-effectiveness of using these risk factors to predict DDH was evaluated using NHS tariffs (January 2021).Aims

The Uppföljningsprogram för cerebral pares (CPUP) Hip Score distinguishes between children with cerebral palsy (CP) at different levels of risk for displacement of the hip. The score was constructed using data from Swedish children with CP, but has not been confirmed in any other population. The aim of this study was to determine the calibration and discriminatory accuracy of this score in children with CP in Scotland. This was a total population-based study of children registered with the Cerebral Palsy Integrated Pathway Scotland. Displacement of the hip was defined as a migration percentage (MP) of > 40%. Inclusion criteria were children in Gross Motor Function Classification System (GMFCS) levels III to V. The calibration slope was estimated and Kaplan-Meier curves produced for five strata of CPUP scores to compare the observed with the predicted risk of displacement of the hip at five years. For discriminatory accuracy, the time-dependent area under the receiver operating characteristic curve (AUC) was estimated. In order to analyze differences in the performance of the score between cohorts, score weights, and subsequently the AUC, were re-estimated using the variables of the original score: the child’s age at the first examination, GMFCS level, head shaft angle, and MP of the worst hip in a logistic regression with imputation of outcomes for those with incomplete follow-up.Aims
Methods
The aim of this study was to report the incidence of implant-related complications, further operations, and their influence on the outcome in a series of patients who underwent primary reverse total shoulder arthroplasty (RTSA). The prospectively collected clinical and radiological data of 797 patients who underwent 854 primary RTSAs between January 2005 and August 2018 were analyzed. The hypothesis was that the presence of complications would adversely affect the outcome. Further procedures were defined as all necessary operations, including reoperations without change of components, and partial or total revisions. The clinical outcome was evaluated using the absolute and relative Constant Scores (aCS, rCS), the Subjective Shoulder Value (SSV) scores, range of motion, and pain.Aims

Introduction and Objective. In recent years, along with the extending longevity of patients and the increase in their functional demands, the number of annually performed RSA and the incidence of complications are also increasing. When a complication occurs, the patient often needs multiple surgeries to restore the function of the upper limb. Revision implants are directly responsible for the critical reduction of the bone stock, especially in the shoulder. The purpose of this paper is to report the use of allograft bone to restore the bone stock of the glenoid in the treatment of an aseptic glenoid component loosening after a reverse shoulder arthroplasty (RSA). Materials and Methods. An 86-years-old man came to our attention for aseptic glenoid component loosening after RSA. Plain radiographs showed a
When the present study was initiated, we changed the treatment for late-detected developmental dislocation of the hip (DDH) from several weeks of skin traction to markedly shorter traction time. The aim of this prospective study was to evaluate this change, with special emphasis on the rate of stable closed reduction according to patient age, the development of the acetabulum, and the outcome at skeletal maturity. From 1996 to 2005, 49 children (52 hips) were treated for late-detected DDH. Their mean age was 13.3 months (3 to 33) at reduction. Prereduction skin traction was used for a mean of 11 days (0 to 27). Gentle closed reduction under general anaesthesia was attempted in all the hips. Concurrent pelvic osteotomy was not performed. The hips were evaluated at one, three and five years after reduction, at age eight to ten years, and at skeletal maturity. Mean age at the last follow-up was 15.7 years (13 to 21).Aims
Methods
The glenohumeral joint is the most frequently dislocated articulation, but possibly due to the lower prevalence of posterior shoulder dislocations, approximately 50% to 79% of posterior glenohumeral dislocations are missed at initial presentation. The aim of this study was to systematically evaluate the most recent evidence involving the aetiology of posterior glenohumeral dislocations, as well as the diagnosis and treatment. A systematic search was conducted using PubMed (MEDLINE), Web of Science, Embase, and Cochrane (January 1997 to September 2017), with references from articles also evaluated. Studies reporting patients who experienced an acute posterior glenohumeral joint subluxation and/or dislocation, as well as the aetiology of posterior glenohumeral dislocations, were included.Aims

The aim of this study was to report the mid-term clinical outcome
of cemented unlinked J-alumina ceramic elbow (JACE) arthroplasties
when used in patients with rheumatoid arthritis (RA). We retrospectively reviewed 87 elbows, in 75 patients with RA,
which was replaced using a cemented JACE total elbow arthroplasty
(TEA) between August 2003 and December 2012, with a follow-up of
96%. There were 72 women and three men, with a mean age of 62 years
(35 to 79). The mean follow-up was nine years (2 to 14). The clinical condition
of each elbow before and after surgery was assessed using the Mayo
Elbow Performance Index (MEPI, 0 to 100 points). Radiographic loosening
was defined as a progressive radiolucent line of >1 mm that was
completely circumferential around the prosthesis.Aims
Patients and Methods
This retrospective study was designed to evaluate
the outcomes of re-dislocation of the radial head after corrective osteotomy
for chronic dislocation. A total of 12 children with a mean age
of 11 years (5 to 16), with further dislocation of the radial head
after corrective osteotomy of the forearm, were followed for a mean
of five years (2 to 10). Re-operations were performed for radial
head re-dislocation in six children, while the other six did not
undergo re-operation (‘non-re-operation group’). The active range
of movement (ROM) of their elbows was evaluated before and after
the first operation, and at the most recent follow-up. In the re-operation group, there were significant decreases in
extension, pronation, and supination when comparing the ROM following
the corrective osteotomy and following
re-operation (p <
0.05). The children who had not undergone re-operation achieved a better
ROM than those who had undergone re-operation. There was a significant difference in mean pronation (76° Cite this article:

We investigated the incidence and risk factors
for the development of avascular necrosis (AVN) of the femoral head in
the course of treatment of children with cerebral palsy (CP) and
dislocation of the hip. All underwent open reduction, proximal femoral
and Dega pelvic osteotomy. The inclusion criteria were: a predominantly
spastic form of CP, dislocation of the hip (migration percentage,
MP >
80%), Gross Motor Function Classification System, (GMFCS) grade
IV to V, a primary surgical procedure and follow-up of >
one year. There were 81 consecutive children (40 girls and 41 boys) in
the study. Their mean age was nine years (3.5 to 13.8) and mean
follow-up was 5.5 years (1.6 to 15.1). Radiological evaluation included
measurement of the MP, the acetabular index (AI), the epiphyseal
shaft angle (ESA) and the pelvic femoral angle (PFA). The presence
and grade of AVN were assessed radiologically according to the Kruczynski
classification. Signs of AVN (grades I to V) were seen in 79 hips (68.7%). A
total of 23 hips (18%) were classified between grades III and V. Although open reduction of the hip combined with femoral and
Dega osteotomy is an effective form of treatment for children with
CP and dislocation of the hip, there were signs of avascular necrosis
in about two-thirds of the children. There was a strong correlation
between post-operative pain and the severity of the grade of AVN. Cite this article:
The use of joint-preserving surgery of the hip
has been largely abandoned since the introduction of total hip replacement.
However, with the modification of such techniques as pelvic osteotomy,
and the introduction of intracapsular procedures such as surgical
hip dislocation and arthroscopy, previously unexpected options for
the surgical treatment of sequelae of childhood conditions, including
developmental dysplasia of the hip, slipped upper femoral epiphysis
and Perthes’ disease, have become available. Moreover, femoroacetabular
impingement has been identified as a significant aetiological factor
in the development of osteoarthritis in many hips previously considered to
suffer from primary osteoarthritis. As mechanical causes of degenerative joint disease are now recognised
earlier in the disease process, these techniques may be used to
decelerate or even prevent progression to osteoarthritis. We review
the recent development of these concepts and the associated surgical
techniques. Cite this article:
Introduction. Alumina-on-alumina bearings exhibit low wear rates in vitro and one commonly used ceramic implant is the Trident system (Stryker, Mahwah, NJ). There are some reports of incomplete seating of the ceramic liner in the Trident acetabular shell. However, it is often difficult to detect incomplete seating intraoperatively. We sought to prevent incomplete seating using intraoperative radiography. Materials and Methods. We retrospectively reviewed 19 hips in 17 patients who had undergone primary total hip arthroplasty using a Trident shell with a metal-backed alumina liner between 2007 and 2010. There were 16 women and 1 man, with an average age of 45.7 years. Preoperative diagnosis revealed 14 cases of osteoarthritis and 5 cases of osteonecrosis. All procedures were performed using a posterolateral approach with PSL cups. The minimum follow-up time was 12 months (average 28 months). All procedures included an intraoperative anteroposterior view radiograph to evaluate cup seating. If incomplete seating was recognized we reinserted the liner. Postoperatively, radiographs (supine anteroposterior and cross table lateral views) and computed tomography were performed in all cases in order to assess any residual incomplete seating. We investigated whether it was possible to avoid incomplete seating using intraoperative radiography. Results. Six (32%)of 19 hips had evidence of incomplete seating. Of these, 3 revealed incomplete seating on intraoperative radiography, 2 were reinserted adequately, and the liner was replaced with a polyethylene liner in one case. Postoperative radiography revealed incomplete seating in 3 cases. One hip had become correctly seated as shown by follow-up radiography at 3 months and the other hips remained incompletely seated for the follow up period. The location of the gap between the socket and liner caused by incomplete seating was inferomedial in all cases, as seen on the intraoperative anteroposterior view radiographs. We were able to avoid incomplete seating in all of these cases except for one, which was missing the gap. Cases in which the location of the gap was anterior could not be diagnosed by intraoperative radiographs, and were diagnosed postoperatively. Incomplete seating was seen in 3 of 9 cases that used a 2.8 mm shell thickness, and in 3 of 10 cases that used a 3.8 mm thickness. No case had
Knee dislocation is a rare injury in high energy trauma, but it is even rarer in low energy injuries. We present, to our knowledge, the only case in the world literature of knee dislocation following a cricketing injury. The patient was a 46 year old recreational fast bowler who, whilst bowling, slipped on the pitch on the follow through. He sustained an anteromedial knee dislocation which was reduced under intravenous sedation. He also sustained a neuropraxia of the common peroneal nerve with grade 2 weakness of ankle and toe dorsiflexion. Magnetic Resonance Imaging (MRI) confirmed a complete rupture of anterior cruciate ligament (ACL), lateral collateral ligament (LCL) and postero-lateral corner (PLC). Patient underwent surgical reconstruction and repair of his PLC along with repair of LCL with combination of anchor sutures and metal staple within 72 hours of the injury. He was treated in a cast brace. The ACL insufficiency was treated conservatively. Patient made an uneventful recovery and follow up at 3 months revealed a full range of knee movements with asymptomatic ACL laxity
Aims. To describe the distribution and clinical presentation of SLAP tears in rugby players, and time taken for return to sport. Method. A retrospective review of 51 shoulder arthroscopies performed on professional rugby players over a 35 month period was carried out. All patients diagnosed with a SLAP lesion at arthroscopy were identified. Each patient's records were reviewed to record age, injury side, mechanism of injury, clinical diagnosis, investigations and results, management, and return to play. Results. The incidence of SLAP tears was 35%. All 18 patients were male with an average age of 27 yrs. There were 11 isolated SLAP tears (61%), 3 SLAP tears associated with a Bankart lesion (17%), 2 SLAP tears associated with a posterior labral lesion (11%) and 2 SLAP tears associated with an anterior and posterior labral injury (11%). Of the 18 SLAP tears, 14 (78%) were Type 2, 3 (17%) were Type 3 and 1 (5%) was Type 4. All patients recalled a specific heavy tackle with fall onto the lateral aspect of shoulder.

acetabular component in patients undergoing total hip replacement
for osteoarthritis secondary to developmental dysplasia of the hip.
The rationale behind its design and the surgical technique used
for its implantation are described. It is distinctly different from
a standard cementless hemispherical component as it is designed
to position the bearing surface at the optimal angle of inclination,
that is, <
45°, while maximising the cover of the component by
host bone.
Purpose: The literature contains little information on an objective method of measuring radiocapitellar joint translations, as would be seen with joint instability. The purpose of this study was to develop and validate a measurement method that was simple and that could be easily reproducible in a clinical setting or intra-operatively to assess radiocapitellar joint translations. Method: We performed a radiological study on a synthetic elbow specimen in order to quantify radial head translations as related to the capitellum: the Radio-capitellum ratio (RCR). Thirty (30) lateral elbow x-rays were taken in different magnitude of subluxation of the radial head. The subluxation was created randomly by manipulation. X-rays where taken by fluoroscopy to obtain a perfect lateral view of the distal humerus. First, the evaluators determined the long axis of the radius and the center of the capitellum. The displacement of the radial head (in mm) was obtained by measuring the distance of the line perpendicular to the long axis of the radius passing through the center of the capitellum. Then, in order to adjust for variation of magnification, a ratio of the displacement of the radial head about the diameter of the capitellum was done. The RC ratio would be of zero because the long axis of the radius always crosses the center of the capitellum in a perfectly aligned joint. A five mm translation of the radial head and a capitellum diameter of twenty (20) mm would give a RCR of 25% and would be positive if anterior and negative if posterior. The measurements were done two times at one week intervals by three independent evaluators to test inter-observer agreement and intra-observer consistency. The radiological incidences were randomly ordered to minimize observer recall bias. Intra/inter-observer reliability was calculated using Intra-Class Correlation (ICC) and paired T-tests. Results: The mean translation in the trial group was of 6,06% (SD 70.7%) from – 167% to 125%. A result over 100% means that it is a
