Introduction and Purpose. Metacarpal fractures constitute approximately one third of all hand fractures. The majority of these fractures are treated by conservative non-surgical methods. The aim of this study is to obtain the appropriate anatomical alignment of the fracture with dynamic metacarpal stabilization splint (DMSS) and to maintain the proper bone anatomy until the union is achieved. In addition, by comparing this method with short arm plaster splint (SAPS) application, it is aimed to evaluate whether patients are superior in terms of comfort, range of motion (ROM) and grip strength. Materials and Methods. In our study, SAPS or DMSS was applied to the patients with 5th metacarpal neck fracture randomly after fracture reduction and followed for 3 months. A total of 119 patients with appropriate criteria were included in the study. Radiological alignment of the fracture and amount of joint movements were evaluated during follow-up. Grip strength was evaluated with Jamar dynamometer. EQ-5D-5L and VAS scores were used for clinical evaluation. Results. 103 patients completed their follow-up. 51 patients were treated with SAPS and 52 patients were treated with DMSS. The mean age of the SAPS was 29.5 (SD ± 9.4; 16–53 years) and the mean age of the DMSS group was 27.8 (SD ± 11.6; 16–63). Pressure sores was seen in 5 patients in the DMSS group, while no pressure sore was seen in the SAPS (p = 0.008). There was no significant difference between the two groups in the VAS scores at all times. There was no significant difference between the mean dorsal cortical angulation (DCA) before the reduction, after the reduction and at the third month follow-ups. There was no statistically significant difference between the length of metacarps at first admittion before reduction, after reduction and at third month follow-ups. When the grip strength of the two groups were compared as a percentage, the grip strength of the patients in the DMSS group was found to be higher at 1st month, 2nd month and 3rd month (p <0.001). When the ROM values of the patients were evaluated, DMSS group had a higher degree of ROM in the first month compared to the SAPS group (p <0.001). No statistically significant difference was detected among groups at third month in the ROM of the IP and MP joints. However, wrist ROM was statistically higher in DMSS group at 3rd month (p <0.05). There was a statistically significant difference between EuroQol scores in favor of DMSA group (p <0.05). Discussion and Conclusion. In stable 5th metacarpal neck fractures, DMSA is as effective as SAPS to maintain bone anatomy. In addition, DMSA can be preferred for fixation plaster splint or circular plaster applications for the prevention of reduction in boxer fractures, with the advantage of having high clinical scores, which is an indication of early acquisition of grip strength, ease of use and patient comfort

Torus (Buckle) fractures of distal radius are common in children and form a major workload of any fracture clinic. They are usually stable and do not displace. Recent evidence has shown that these fractures can be safely treated in a futura splint. In UK, many of the hospitals are still treating these patients with full plaster. Bringing back these patients to fracture clinic for plaster removal means more workload and places more financial burden in the NHS. Our study is a completed audit cycle where we successfully implemented treatment with futura splint. Over a period of 6 months, 25 torus fractures were diagnosed & treated in A/E back slab. Mean age was 8.24 (Range: 3–12 yrs). Most common MOI was fall on outstretched hand. All cases had presented to A/E within 24 hours. 5 were given futura splint at the fracture clinic. 21 cases received full plaster. They were seen back in clinic in 3–4 weeks for plaster removal. After this audit was presented, we started treating these fractures with futura splint. Reauditing 6 months later revealed that of 31 cases, we had successfully treated 28 with Futura splint. 2 were treated with plaster on parent's insistence. The remaining one was treated in plaster as we could not fit a futura splint. There were no problems reported with futura splint. By definition, torus fractures are stable. The major problem with these fractures lies in the correct diagnosis. We have treated this fracture successfully with futura splint. Recent papers have shown that every patient treated with futura splint saves nearly £53 when compared to plaster treatment. Implementing this treatment has reduced plaster related problems. We hope this audit will help in changing practice in other hospitals in NHS

Intramedullary nails (IMNs) are the current gold standard for treatment of long bone diaphyseal and selected metaphyseal fractures. Their design has undergone many revisions to improve fixation techniques, conform to the bone shape with appropriate anatomic fit, reduce operative time and radiation exposure, and extend the indication of the same implant for treatment of different fracture types with minimal soft tissue irritation. The IMNs are made or either titanium alloy or stainless steel and work as load-sharing internal splints along the long bone, usually accommodating locking elements – screws and blades, often featuring angular stability and offering different configurations for multiplanar fixation – to secure secondary fracture healing with callus formation in a relative-stability environment. Bone cement augmentation of the locking elements can modulate the construct stiffness, increase the surface area at the bone-implant interface, and prevent cut-through of the locking elements. The functional requirements of IMNs are related to maintaining fracture reduction in terms of length, alignment and rotation to enhance fracture healing. The load distribution during patient's activities is along the entire bone-nail interface, with nail length and anatomic fit being important factors to avoid stress risers

Introduction. As per national guidelines for Ankle fractures in the United Kingdom, fractures considered stable can be treated with analgesia, splinting and allowed to weight bear as tolerated. The guidelines also suggest further follow-up not mandatory. This study was aimed at evaluating the current clinical practice of managing stable ankle fractures at a university hospital against national guidelines. Method. The study was undertaken using retrospectively collected data, the inclusion criteria being all adults with stable ankle fracture pattern treated non-operatively between December 2022 and April 2023. Collected data included age of patient, date of injury, type of immobilization, number of clinical visits and any complications. Results. 41 cases were identified and analyzed. The mean age of the cohort was 49.8 years (Standard deviation 20.01). Twelve percent (n = 5) were reviewed in clinic, treated and discharged as stable Weber B type fracture pattern as per national guidelines after the first visit. About 52% (n = 21) were seen in clinic twice before discharge, first visit between 1-2 weeks and the last clinic visit between 5-7 weeks. About a third of patients (30%, n = 12) were seen in clinic on more than two occasions. At the first clinic visit 87% (n = 36) were given a boot and allowed to weight bear as tolerated. Two patients were diagnosed with deep vein thrombosis/pulmonary embolism during the treatment duration. Three patients had extended duration of follow up for ongoing symptoms. None discharged after first or second visit needed surgery for displaced or malunited fracture. Conclusion. Patients discharged from clinic after first or second visit did not need any further surgery. As per national guidelines, patients deemed stable weber B lateral malleolus fracture pattern after weight bearing radiograph can be treated safely with a weight bearing walking boot with no further follow up

Aims & Background. Congenital Talipes Equinovarus (CTEV) is the most common congenital musculoskeletal birth defect affecting 1 in 1000 births per annum. We have compared our surgical results to the British Society of Children's Orthopaedics (BSCOS) published guidelines. Methods. Between, 2006–16, patients who were referred for treatment of pathological CTEV were audited. Data from a combination of Clinical Portal, Orthotic Patient Administration System and Surgical Elogbook were assessed. In addition, the degree of deformity was classified by the Harrold & Walker method at the time of diagnosis (senior author). Most of this information was recorded prospectively and analysed retrospectively. Ponseti technique was the method of treatment. Results. 96 patients assessed (133 feet). There were 78 males and 18 females, 37 patients were affected bilaterally and 11 had associated syndromes. There were 23 Harrold & Walker (H&W) 1, 28 H&W 2 and 82 H&W 3 classification feet. Average time period in Ponseti boots and bars was 14.4 months (95% CI 12.9–15.9), average time in all types of bracing of was 17.1 months (95% CI 14.8–14.8). Number and rate of surgeries performed were as follows: 77 Tendoachilles release (63.1%), 19 Tibialis Anterior Transfer (5.6%), 15 Radical Release (12.3%), revision 25 Surgery (20.5%) & 5 Abductor Hallucis Release (4.1%). Conclusion. The audit confirms that the unit meets most of the current BSCOS guidelines. All surgical procedures apart from radical release surgery fall within accepted limits. This may be due, in part, to the syndromal cases. We do however demonstrate a significantly reduced average time period in bracing compared to that recommended by BSCOS. There are multiple reasons for this discrepancy including non-compliance and poor splint tolerance (child refusing to use). We feel this work demonstrates a reduced period in bracing can be achieved whilst maintaining standards of treatment

Utilization of nerve conduction studies in the investigation and management of carpal tunnel syndrome varies according to their perceived usefulness and availability. The use of steroid injections and splinting also varies according to service availability and their perceived effectiveness. We present a three year follow up of 230 patients managed in an environment where nerve conduction testing was not readily available. The majority received splinting and a steroid injection in an effort to manage their symptoms conservatively in the first instance. Our results show that a clear majority of patients who were treated with initial splinting and steroid injections saw a recurrence of their symptoms (71.9% and 79.7% respectively) requiring eventual surgical decompression. These results would seem to suggest that conservative management of carpal tunnel does not produce the desired curative results and that there may be an argument for proceeding directly to surgery. We also showed that 55% of patients referred for Nerve Conduction Studies seem to progress to surgical decompression. This would seem to suggest that Nerve Conduction Studies could form a robust part of the standard investigation of carpal tunnel in order to identify those who would benefit from surgery

The Cochrane Collaboration has produced five new reviews relevant to bone and joint surgery since the publication of the last Cochrane Corner These reviews are relevant to a wide range of musculoskeletal specialists, and include reviews in Morton’s neuroma, scoliosis, vertebral fractures, carpal tunnel syndrome, and lower limb arthroplasty.

Summary. For injuries to the lower leg or forearm, supplemental support from soft tissue compression (STC) with a splint or brace-like system and combined with external fixation could be done effectively and quickly with a minimal of facilities in the field. Introduction. Soft tissue compression (STC) in functional braces has been shown to provide rigidity and stability for most closed fractures, selected open fractures and can supplement some other forms of fracture fixation. However, soft tissue injuries are compromised in war injuries. This study was designed to evaluate if STC can provide adequate rigidity and stability either with, or without other forms of fixation techniques of simple fractures or bone defects after standardised soft tissue defects. The load was applied either axially or in bending as the bending configuration is more like conditions when positioned on a stretcher in the field. Methods. A simple, oblique fracture was created in 23 cadaveric femurs, 23 tibiae and fibulae, 22 humeri and 22 radii and ulnae of intact limb segments. The weight of each intact limb segment was measured. Cyclic axial loads (12 – 120N) were applied for each progressive condition: intact limb, mid shaft osteotomy, a lateral 1/4 circumferential soft tissue defect, 1/3 circumferential defect and finally, 3 cm bone defect. Limbs were randomly assigned to be stabilised be either plate and screw (PS), intramedullary rod (IR) or external fixation (EF). Testing with and without STC in a brace was performed after each condition. In an additional 36 forearms, bending rigidity was measured using a modular fracture brace with external fixation. The bone and the soft tissue weighed separately and the ratio of soft tissue to bone was calculated. ANOVA multi-variant analysis corrected for multiple comparisons was used to compare the axial rigidity between the different conditions tested. Results. There was no significant difference in axial rigidity for humerus or femoral shaft fractures treated by any of the methods related to the degree of soft tissue damage. Femurs, tibias and humeri with a 3 cm bone defect were best stabilised with IR. Forearms with a 3 cm bone defect were best stabilised with PS. Progressive increase in soft tissue defects did create progressive loss in rigidity in forearms and legs, but the most dramatic loss occurred with the bone defect and ST defect. The rigidity of IR and EF in legs decreased over 50% with bone defect, and about 20% of that was restored with STC. The rigidity of IR and EF in forearms decreased almost 79%, and about 21% of that was restored with STC. The increase in resistance to bending in the forearm was most significantly improved by STC. Discussion/Conclusions. Invasive types of surgical intervention provide the best rigidity to fractures, regardless of the presence of or size of a soft tissue defect. In general, use of PS and IR and application of conventional types of braces to achieve STC is not practical in the field. EF, however, can be applied quickly and easily with a minimal of facilities in the field and can be applied in such a way that no foreign bodies end up in the contaminated wound. For injuries to the leg or forearm, supplemental support from STC with a splint or brace-like system could be effective

Background. Surgical management of calcaneus fractures is demanding and has a high risk of wound complications. Traditionally these fractures are managed with splinting until swelling has subsided. We describe a novel protocol for the management of displaced intra-articular calcaneus fractures utilising a temporizing external fixator and staged conversion to plate fixation through a sinus tarsi approach. The goal of this technique is to allow for earlier treatment with open reduction and internal fixation, minimise the amount of manipulation required at the time of definitive fixation and reduce the wound complication rate seen with the extensile approach. Methods. The records of patients with displaced calcaneus fractures from 2010–2014 were retrospectively reviewed. A total of 10 patients with 12 calcaneus fractures were treated with this protocol. All patients underwent ankle-spanning medial external fixation within 48 hours of injury. Patients underwent conversion to open plate fixation through a sinus tarsi approach when skin turgor had returned to normal. Time to surgery, infection rate, wound complications, radiographic alignment, and time to radiographic union were recorded. Results. The average Bohler's angle improved from 13.2 (range −2 to 34) degrees preoperatively to 34.3 (range 26 to 42) degrees postoperatively. The average time from external fixation to conversion to internal fixation was 4.8 (range 3 to 7) days. There were no immediate post-surgical complications. The average time to weight bearing was 8.5 weeks. The average time to radiographic union was 9.5 (range 8 to 12) weeks. There were no infections or wound complications at the time of last follow-up. Conclusions. Early temporizing external fixation for the acute management of displaced calcaneus fractures is a safe and effective method to reduce and stabilise the foot and may decrease the time to definitive fixation. In our series there were no complications related to the use of the external fixator. Level of Evidence. IV Retrospective case series

Adequate range of knee motion is critical for successful total knee arthroplasty. While aggressive physical therapy is an important component, manipulation may be a necessary supplement. There seems to be a lack of consensus with variable practices existing in managing stiff postoperative knees following arthroplasty. Hence we did a postal questionnaire survey to determine the current practice and trend among knee surgeons throughout the United Kingdom. A postal questionnaire was sent out to 100 knee surgeons registered with British Association of Knee Surgeons ensuring that the whole of United Kingdom was well represented. The questions among others included whether the surgeon used Manipulation Under Anaesthaesia (MUA) as an option for stiff postoperative knees; timing of MUA; use of Continuous Passive Motion (CPM) post-manipulation. We received 82 responses. 46.3% of the respondents performed MUA routinely, 42.6% sometimes, and 10.9% never. Majority (71.2%) performed MUA within 3 months of the index procedure. 67.5% routinely used CPM post-manipulation while 7.3% of the respondents applied splints or serial cast post MUA. 41.5% of the surgeons routinely used Patient Controlled Analgaesia +/− Regional blocks. Majority (54.8%) never performed open/arthroscopic debridement of fibrous tissue for adhesiolysis. Knee manipulation requires an additional anaesthetic and may result in complications such as: supracondylar femur fractures, wound dehiscence, patellar tendon avulsions, haemarthrosis, and heterotopic ossification. Moreover studies have shown that manipulation while being an important therapeutic adjunct does not increase the ultimate flexion that can be achieved which is determined by more dominant factors such as preoperative flexion and diagnosis. Manipulation should be reserved for the patient who has difficult and painful flexion in the early postoperative period

Objectives

Mesenchymal stem cells have the ability to differentiate into various cell types, and thus have emerged as promising alternatives to chondrocytes in cell-based cartilage repair methods. The aim of this experimental study was to investigate the effect of bone marrow derived mesenchymal stem cells combined with platelet rich fibrin on osteochondral defect repair and articular cartilage regeneration in a canine model.

The aim of this experimental study on New Zealand’s white rabbits was to investigate the transplantation of autogenous growth plate cells in order to treat the injured growth plate. They were assessed in terms of measurements of radiological tibial varus and histological characteristics.

This review is aimed at clinicians appraising preclinical trauma studies and researchers investigating compromised bone healing or novel treatments for fractures. It categorises the clinical scenarios of poor healing of fractures and attempts to match them with the appropriate animal models in the literature.

We performed an extensive literature search of animal models of long bone fracture repair/nonunion and grouped the resulting studies according to the clinical scenario they were attempting to reflect; we then scrutinised them for their reliability and accuracy in reproducing that clinical scenario.

Models for normal fracture repair (primary and secondary), delayed union, nonunion (atrophic and hypertrophic), segmental defects and fractures at risk of impaired healing were identified. Their accuracy in reflecting the clinical scenario ranged greatly and the reliability of reproducing the scenario ranged from 100% to 40%.

It is vital to know the limitations and success of each model when considering its application.

An experimental piglet model induces avascular necrosis (AVN) and deformation of the femoral head but its secondary effects on the developing acetabulum have not been studied. The aim of this study was to assess the development of secondary acetabular deformation following femoral head ischemia.

The aim of this randomised, controlled in vivo study in an ovine model was to investigate the effect of cylic pneumatic pressure on fracture healing. We performed a transverse osteotomy of the right radius in 37 sheep. They were randomised to a control group or a treatment group where they received cyclic loading of the osteotomy by the application of a pressure cuff around the muscles of the proximal forelimb. Sheep from both groups were killed at four or six weeks. Radiography, ultrasonography, biomechanical testing and histomorphometry were used to assess the differences between the groups. The area of periosteal callus, peak torsional strength, fracture stiffness, energy absorbed over the first 10° of torsion and histomorphometric analysis all showed that the osteotomies treated with the cyclic pneumatic pressure at four weeks were not significantly different from the control osteotomies at six weeks.

Using an osteotomy of the olecranon as a model of a transverse fracture in 22 cadaver elbows we determined the ability of three different types of suture and stainless steel wire to maintain reduction when using a tension-band technique to stabilise the bone. Physiological cyclical loading simulating passive elbow movement (15 N) and using the arms to push up from a chair (450 N) were applied using an Instron materials testing machine whilst monitoring the osteotomy site with a video extensometer. Each osteotomy was repaired by one of four materials, namely, Stainless Steel Wire (7), No 2 Ethibond (3), No 5 Ethibond (5), or No 2 FiberWire (7).

There were no failures (movement of > 2 mm) with stainless steel wire or FiberWire and no significant difference in the movements measured across the site of the osteotomy (p = 0.99). The No. 2 Ethibond failed at 450 N and two of the five of No. 5 Ethibond sutures had a separation of > 2 mm at 450 N.

FiberWire as the tension band in this model held the reduction as effectively as stainless steel wire and may reduce the incidence of discomfort from the hardware. On the basis of our findings we suggest that a clinical trial should be undertaken
