Combined electric and magnetic field therapy for bone repair and regeneration: an investigation in a 3-mm and an augmented 17-mm tibia osteotomy model in sheep.

BACKGROUND: Therapies using electromagnetic field technology show evidence of enhanced bone regeneration at the fracture site, potentially preventing delayed or nonunions. METHODS: Combined electric and magnetic field (CEMF) treatment was evaluated in two standardized sheep tibia osteotomy models: a 3-mm non-critical size gap model and a 17-mm critical size defect model augmented with autologous bone grafts, both stabilized with locking compression plates. CEMF treatment was delivered across the fracture gap twice daily for 90 min, starting 4 days postoperatively (post-OP) until sacrifice (9 or 12 weeks post-OP, respectively). Control groups received no CEMF treatment. Bone healing was evaluated radiographically, morphometrically (micro-CT), biomechanically and histologically. RESULTS: In the 3-mm gap model, the CEMF group (n = 6) exhibited higher callus mineral density compared to the Control group (n = 6), two-fold higher biomechanical torsional rigidity and a histologically more advanced callus maturity (no statistically significant differences). In the 17-mm graft model, differences between the Control (n = 6) and CEMF group (n = 6) were more pronounced. The CEMF group showed a radiologically more advanced callus, a higher callus volume (p = 0.003) and a 2.6 × higher biomechanical torsional rigidity (p = 0.024), combined with a histologically more advanced callus maturity and healing. CONCLUSIONS: This study showed that CEMF therapy notably enhanced bone healing resulting in better new bone structure, callus morphology and superior biomechanical properties. This technology could transform a standard inert orthopedic implant into an active device stimulating bone tissue for accelerated healing and regeneration.

Photobiomodulation therapy combined with static magnetic field in tibial fracture healing of a dog: A case report.

A 10-week-old male, Xoloitzcuintle (Mexican hairless dog), weighing 8.9 kg was presented after its owner accidentally stepped on its paw. The dog presented with acute pain, inflammation and grade IV lameness in the right hind paw. A complete transverse fracture in the right proximal tibia was diagnosed from radiography. The dog underwent a minimally invasive plate osteosynthesis (MIPO) procedure. After surgery, photobiomodulation therapy combined with static magnetic field (PBMT-sMF) was applied twice daily for 21 days. A multi-wavelength PBMT-sMF device was applied at three sites using different frequencies: proximal and distal of the fracture zone (3000 Hz, 40.35 J per site, and 300 s per site) and in the fracture zone (250 Hz, 39.11 J and 300 s per site). Follow up radiographies were performed after surgery and treatment with PBMT-sMF. Eighteen days post-surgery the healing process of bone was advanced. Fifty-five days post-surgery the callus was enlarged. In addition, radiographic union and clinical union was evidenced by closure of the fracture gap. This case report has reported the use of PBMT-sMF in order to accelerate and improve bone healing following a MIPO procedure on a complete transverse fracture in the proximal tibia of a puppy.

Intramedullary application of local antibiotic bullets for the treatment of long bone fracture related infection.

PURPOSE: The optimal means of local antibiotic delivery for fracture related infection is unknown. Until now, intramedullary application of calcium sulphate based local antibiotics has been challenging. We report on the use of a newly available mode of preparation and delivery: the Stimulan Bullet Mat and Introducer (Biocomposites Ltd, Staffordshire, England). METHODS: A retrospective analysis of prospectively collected data for infection cases at two separate tertiary referral institutions was performed. We included cases of long bone FRI with a retained intramedullary nail, treated with a single stage protocol of metalwork removal, debridement, local antibiotic application using the novel mould and applicator, with additional bony stabilisation and soft tissue reconstruction where required. RESULTS: All 13 patients achieved infection remission rate with an average follow-up of 19.7 months (range 12-28). All 6 patients with infection around an unhealed fracture achieved union at an average 8 months (range 4-12) from debridement. No patients developed aseptic wound leak. CONCLUSIONS: Antibiotic impregnated calcium sulphate can be used safely as part of a single stage treatment protocol for the treatment of long bone fracture related infection following intramedullary nailing. We have demonstrated high rates of infection remission and union, using a newly available intramedullary applicator.

[Correlation analysis of serum CTRP3 and PGC-1α expression with traumatic fracture healing].

OBJECTIVE: To investigate the relationship between serum C1q/tumor necrosis factor-related protein-3(CTRP3) and peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α) on predictive value of expression level on fracture healing. METHODS: From January 2019 to January 2020, 80 patients with traumatic tibial plateau fractures were treated by internal fixation with support plates through the posterior approach of the knee joint. The patients were followed up for 12 months. According to the criteria for delayed fracture healing, the patients were divided into two groups:54 patients in fracture healing group included 24 males and 30 females, aged 29 to 75 years old with an average of (52.36±13.17) years;In the delayed healing group, there were 26 cases, 13 males and 13 females, aged from 29 to 75 with an average od (53.82±13.52) years. The serum levels of CTRP3, PGC-1αand 25 hydroxyvitamin D3[25(OH)D3] in patients with traumatic fracture were detected by enzyme-linked immunosorbent assay(ELISA);Blood phosphorus and calcium levels were measured by automatic biochemical analyzer, and the product of calcium and phosphorus was calculated;Pearson's method was used to analyze the correlation between serum CTRP3, PGC-1αand bone biochemical indexes in patients with delayed union one week after operation;The predictive value of serum levels of CTRP3 and PGC-1αon traumatic fracture healing was analyzed by receiver operating characteristic curve(ROC curve). RESULTS: PGC-1α, calcium phosphorus product and 25(OH)D3 in the fracture healing group were higher than those in the delayed healing group at 1 and 4 weeks after operation(P<0.05). Serum CTRP3 was positively correlated with PGC-1α(r=0.637, P<0.05) and positively correlated with calcium phosphorus product and 25(OH)D3(P<0.05). The areas under the curve(AUC) of serum ctrp3 and PGC-1α levels in predicting traumatic fracture healing were 0.845 and 0.855, respectively. The cutoff values were 188.678 pg/ml and 2.697 ng/ml, respectively. The specificity was 96.2% and 80.8%, and the sensitivity was 53.7% and 77.8%;The predicted AUC was 0.904, the specificity was 88.5%, and the sensitivity was 81.5%. CONCLUSION: The serum levels of CTRP3 and PGC-1 in patients with delayed union of traumatic fracture at 1 and 4 weeks after operation α The expression level is of certain reference value to predict the fracture healing status of patients.

[Clinical study of digital six-axis external fixation frame based on CT data for tibiofibular fractures].

Objective: To investigate the clinical effect of applying the digital six-axis external fixation frame based on CT data in the treatment of tibiofibular fractures. Methods: The clinical data of 43 patients with tibiofibular fractures treated by the self-developed digital six-axis external fixation frame based on CT data at Integrated Orthopedic Department of Traditional Chinese Medicine (TCM) and Western Medicine,HongHui Hospital from January 2018 to January 2021 were retrospective analysis.There were 27 males and 16 females,aged (36.0±9.4) years(range:25 to 50 years).AO classification:15 cases of 42A,11 cases of 42B, and 17 cases of 42C.There were 7 open fractures and Gustilo fracture classification:2 cases of type Ⅰ,4 cases of type Ⅱ,and 1 case of type Ⅲ.The two or three plane rings were connected with six connecting rods to form a complete six-axis external fixation frame,and the distal and proximal fracture blocks were connected to the distal and proximal rings by fixation pins,and the lengths of the six connecting rods needed to be adjusted were calculated by using the supporting software according to the CT data after surgery,and then the lengths of the connecting rods were adjusted one by one to complete the reduction of the fracture. The reduction accuracy of this six-axis external fixation brace was evaluated by measuring postoperative radiographs; postoperative recovery and complications were collected,the time of brace removal was recorded,and the function of the affected limb was evaluated according to the Johner-Wruhs score at the final follow-up. Results: Postoperative radiographs showed that all patients achieved satisfactory reduction with lateral displacement(M(IQR)) of 2.3(2.5) mm (range:0.3 to 7.3 mm),anteroposterior displacement of 2.1 (2.4) mm (range:0.3 to 5.7 mm),anteroposterior angulation of 2.5(2.4)°(range:0 to 5°),internal and external angulation of 2.1(1.5)°(range:0 to 4°), and no significant internal or external rotational deformity was detected on the exterior.On the second postoperative day,all patients were able to walk with partial weight-bearing on crutches. All 43 patients were followed up for more than 6 months,with a follow-up period of (33.3±7.3) weeks (range:24 to 42 weeks).The external fixation frame was removed after the fracture healed.The external frame was removed at 20(3)weeks (range:18 to 25 weeks) postoperatively. Up to the final follow up, no secondary fracture occurred in any of them.The Johner-Wruhs score of the affected limb at the last follow-up was excellent in 39 cases and good in 4 cases. Conclusion: The digital six-axis external fixator based on CT data for tibiofibular fractures has the advantages of precise reduction,firm fixation,simple operation,rapid fracture healing,and minimal trauma, which is a minimally invasive method for treating tibiofibular fractures,especially suitable for patients with poor skin and soft tissue conditions such as open injuries.

Use of a Porous Alumina Antibiotic-Loaded Ceramic to Treat Bone Defect and Bone Infection After Road Trauma.

To describe the use of a porous alumina ceramic loaded with antibiotics for the reconstruction of bilateral tibial fractures in a patient who presented with bone loss and infection after a motorcycle road injury. A 70-year-old man presented open fractures of his both tibiae (proximal involvement on the right side and diaphyseal on the left side). After initial treatment with multiple débridements and the placement of bilateral external fixators, he had bone loss to both tibiae and had developed infections of both legs with multiple organisms identified (Stenotrophomonas maltophilia, Enterobacter cloacae, and Pseudomonas aeruginosa). We used a porous alumina ceramic, designed according to the defects to fill. This ceramic was loaded with antibiotics (gentamicin and vancomycin). The goal was to obtain locally high concentrations of antibiotics to eradicate bacteria that could have remain in the surgical wound. Ceramic parts were placed 4 months after the trauma. Local antibiotic concentrations largely exceeded the pharmacological parameters for antibiotics efficacy. External fixators were removed 3 months after implantation. After a follow-up of more than 1 year, there is no relapse of infection, and the patient resumed walking while ceramic parts were left in place and that bone started colonizing ceramic parts. This ceramic that combines strength and the possibility of antibiotic loading allows thinking of new ways to treat infected fractures with bone loss. Indeed, its mechanical strength provides primary stability, and antibiotics make it possible to secure implantation in an infected area.

Twenty Years Development of Tibial Cortex Transverse Transport Surgery in PR China.

Tibial cortex transverse transport (TTT) surgery is an extension of the Ilizarov technique. Based on the law of tension-stress, its primary function is to rebuild microcirculation which can relieve ischemic symptoms and promote wound healing. It has received more and more scholars' attention and has experienced a series of changes for 20 years since it entered PR China. The mechanisms involved have gradually become clear, such as the reconstruction of the polarization balance of macrophages, the promotion of vascular tissue regeneration, and the mobilization and regulation of bone marrow-derived stem cells. TTT technique is mainly used in the treatment of chronic ischemic diseases of the lower extremities. It has recently been successfully used in the treatment of primary lymphedema of the lower extremities. A series of improvements have been made in the external fixator's style, the size of skin incision and osteotomy, and distraction method. For example, the annular external fixator has been redesigned as a unilateral external fixator, and accordion technology has been introduced. For distraction methods after surgery, there was no uniform standard in the past. The technique can also be used in combination with other treatments to achieve better effects, such as interventional therapy, negative pressure sealed drainage, 3D printing technology, traditional Chinese medicine. Nevertheless, the surgery may bring some complications, such as secondary fracture, nail infection, skin necrosis at the surgical site, etc. Reports of complications and doubts about the technique have made the TTT technique controversial. In 2020, the relevant expert consensus was published with treatment and management principles, which might guide the better application and development of this technique.

Antibiotic calcium sulfate-loaded hybrid transport versus traditional Ilizarov bone transport in the treatment of large tibial defects after trauma.

BACKGROUND: The purpose of this study was to compare the clinical effects of antibiotic calcium sulfate-loaded hybrid transport (ACSLHT) and traditional Ilizarov bone transport (TIBT) in the treatment of large tibial defects after trauma. METHODS: Eighty-five patients with large tibial defects after trauma were selected for retrospective study. The range of tibial defects was 6-22 cm. After thorough debridement and infection controlled, bone transport technique was used to reconstruct tibial defects. Forty-four patients were treated with ACSLHT technique (the ACSLHT group), while the other 41 were treated with TIBT technique (the TIBT group). Time in external fixator was evaluated by EFI score. Enneking score was used to evaluate limb functions. SAS score was used to evaluate postoperative anxiety status. In addition, complication incidence was compared, including axis deviation, docking site nonunion, infection recurrence and so on. RESULTS: There was no significant difference in preoperative general data between ACSLHT and TIBT group. EFI score in ACSLHT and TIBT group was 0.6 ± 0.1 cm/month and 1.7 ± 0.3 cm/month, respectively (P < 0.05). Enneking score of ACSLHT and TIBT group was 86.5% and 75.1% (P < 0.05). SAS score of ACSLHT group was significantly lower than that of TIBT group (P < 0.05). Complication incidence in ACSLHT group was significantly lower than that in TIBT group (P < 0.05). CONCLUSIONS: Compared with TIBT group, ACSLHT group had shorter time in external fixator, better limb functions, lower postoperative anxiety score and lower complication incidence which is worth of clinical promotion.

Gastrocnemius muscle flap with vancomycin/gentamicin-calcium sulfate and autogenous iliac bone graft for the phase I treatment of localized osteomyelitis after tibial plateau fracture surgery.

PURPOSE: To investigate the clinical effect of gastrocnemius muscle flaps combined with vancomycin/gentamicin-calcium sulfate combined and autologous iliac bone graft in the phase I treatment of traumatic focal osteomyelitis (Cierny-Mader type III) after tibial plateau fracture surgery. METHODS: From July 2009 to January 2018, 35 patients with localized osteomyelitis (Cierny-Mader type III) who met the inclusion criteria were followed up and treated. All patients were infected after undergoing internal fracture fixation surgery. Among them, 18 cases were plate-exposed, 14 cases were due to sinus tracts, two were due to skin necrosis, and one was bone-exposed. We treated patients with several measures. All cases were then followed up. The follow-up indicators included Hospital for Special Surgery knee scores (HSS), the time of laying drainage pipe, bone healing time, infection control rate, and the incidence of nonunion and other complications. RESULTS: All patients were followed up for 24-60 months. None of them underwent amputation. For repairing soft tissue defects, 17 cases were covered with a muscle flap using the medial head of gastrocnemius alone, 15 cases were treated with the lateral head of gastrocnemius muscle, and three cases were covered with the combination of the two heads. Compared to the preoperative score, we found that the average HSS improved at the 1-year and 2-year follow-up (54 vs. 86 vs. 87). CONCLUSION: Using a gastrocnemius muscle flap combined with vancomycin/gentamicin-calcium sulfate and autogenous iliac bone was an effective method for the phase I treatment of osteomyelitis (Cierny-Mader type III) after tibial plateau fracture surgery. In the primary treatment of focal traumatic osteomyelitis, it can decrease the treatment time, number of surgeries, pain of patients, time of bone healing, postoperative exudation, and infection recurrence rate and increase the healing bone's strength.

[Modified posteromedial approach via lateral side of flexor hallucis longus for the treatment of posterior Pilon fracture].

Objective: To compare the clinical efficacy and the level of muscle and soft tissue damage between modified posteromedial approach via lateral side of flexor hallucis longus and modified posteromedial approach in the treatment of posterior Pilon fracture. Methods: Total of 43 patients (27 males and 16 females, aged from 19 to 71 years) diagnosed with posterior Pilon fracture from June 2016 to June 2018 in Foshan Hospital of Traditional Chinese Medicine were randomly divided into observation group (modified posteromedial approach via lateral side of flexor hallucis longus, 21 cases) and control group (modified posteromedial approach, 22 cases) according to the operation approach. The preoperative waiting time, intraoperative time, intraoperative blood loss, hospitalization time and the complications were recorded and compared between the two groups. The differences of blood creatine kinase (CK), myoglobin (Myo) and C-reactive protein (CRP) at different time points before and after operation were compared between the two groups to elevate the level of muscle and soft tissue damage. The fracture reduction qualities of the two groups were compared by Burwell-Charnley criteria. The differences of fracture healing time, range of motion of metatarsophalangeal joint of the great toe (MTP-ROM), ankle range of motion (Ankle-ROM), American Orthopaedic Foot & Ankle Society (AOFAS) score and visual analogue scale (VAS) score of pain were compared between the two groups at the last follow-up. Results: The observation group and the control group were followed-up for (19±6) months and (16±8) months, respectively; there was no significant difference between the two groups (P>0.05). There were no significant differences in preoperative waiting time, intraoperative blood loss, hospitalization time and fracture healing time between the two groups (all P>0.05). At the last follow-up, there was no significant difference in the MTP-ROM and Ankle-ROM between the two groups (both P>0.05); the AOFAS score of the observation group was 88.2±7.8 and it was 84.5±7.6 in the control group (P>0.05); the VAS score of the observation group was (0.9±1.0) and it was (1.3±0.8) in the control group(P>0.05). Anatomical reduction rate in observation group was higher than that in control group (90.5% vs 81.8%, P>0.05). The operation time in the observation group was (87±16) min and it was (98±11) min in the control group (P<0.05). CK, Myo and CRP were increased in both groups after surgery, but there was no statistical significance between groups at the same time point (all P>0.05). There was no nerve injury in the observation group, while 2 cases (9.0%) of nerve paralysis occurred in the control group. No incision infection and checkrein deformity of the Hallux was found in the two groups. Conclusion: The modified posteromedial approach via lateral side of flexor hallucis longus can obtain good operative field exposure, and does not increase muscle and soft tissue injury, with shorter operative time and fewer complications, without nerve injury and checkrein deformity, it is a safe approach for the treatment of posterior Pilon fracture.

Is lower limb salvage worthwhile after severe open tibial fractures in a developing country? An analysis of surgical outcomes, quality of life and cost implications.

INTRODUCTION: Open tibial fractures are rare and difficult-to-treat injuries because of the involvement of bony, skin and neuromuscular injury along with co-morbidities. Often, during the management of very severe cases these injuries, the question arises, should we amputate or salvage the limb? This question has been explored previously in civilian and military contexts in the US and UK but remains unstudied in the alternative sociocultural and economic context of the developing world. METHODS: We studied 78 adult patients with severe open tibial fracture that presented to our institution, a Level 1 trauma center in India, from February 2018 to June 2019. 20 patients underwent above-knee amputation (AKA), 16 underwent below-knee amputation (BKA), and 42 underwent limb salvage. We assessed injury severity using [our institution's] Open Injury Severity Score (GHOISS), which has separate sub-scores for bony injury, skin injury, neuromuscular injury and co-morbidities, and patients were only included with GHOISS > 13. We assessed functional outcome measures as well as economic costs as primary cost levied by our institution and other secondary costs. RESULTS: Salvage (LEFS: mean=51, SF-12 PCS: mean=48, SF-12 MCS: mean=49) provided better outcomes to BKA (LEFS: mean=39, p=0.005, SF-12 PCS: mean=40, p=0.003, SF-12 MCS: mean=43, p=0.052) and AKA (LEFS: mean=31, p<0.001, SF-12 PCS: mean=34, p<0.001, SF-12 MCS: mean=43, p=0.043). Primary costs were higher for limb salvage (index: mean=$3100, total: mean=$4400) than both BKA (index: mean=$2500, p=0.012, total: mean=$2600, p<0.001) and AKA (index: mean=$2800, p=0.020, total: mean=$3200, p<0.001). Secondary costs were higher for limb salvage than both BKA and AKA (p<0.001). Patients who underwent salvage were more likely to return to work at 36 months post-injury compared to below-knee amputees (adjusted OR=0.11, p=0.010). CONCLUSIONS: Limb salvage results in better functional outcomes compared with amputation at a higher upfront cost but a likely lower lifetime cost. Unlike other literature on the topic, amputation carries a heavy mental and physical toll in India, likely due to sociocultural differences and stigma. Amputation is a difficult decision for patients to accept and results in poorer outcomes; therefore, we believe that limbs should be aggressively salvaged in our developing country. STUDY DESIGN: Therapeutic Level II Prospective Cohort Study.

Analgesic effect of music during wound care among patients with diaphyseal tibial fractures: Randomized controlled trial.

BACKGROUND: Evidence is scarce regarding the analgesic effect of music for the relief of acute pain during the care of surgical tibial fracture wounds. OBJECTIVE: To evaluate the analgesic effect of music on acute procedural pain during the care of surgical tibial fracture wounds. METHOD: This was a randomized, controlled, blinded clinical trial with 70 patients in the immediate postoperative period for diaphyseal tibial fracture surgery. Participants were randomly allocated to two groups: a control group (CG), in which patients received only the institution's standard analgesia, and an intervention group (IG) composed of patients receiving a 30-min session of music of their own choice, as a complementary method to the institution's standard analgesia. Pain was evaluated during the first postoperative dressing change, using the Numerical Rating Scale (NRS). RESULTS: The sample was homogeneously composed of men (91.4%), young adults (61.4%), without previous diseases (88.6%) and whose traumas were related to a motorcycle crash (84.3%). The main musical genres chosen by participants were the most popular in their region (61.4%). Those who listened to music presented lower pain scores when compared with those in the CG (IG:2.4 ± 2.4 versus CG:5.8 ± 2.7; p < 0.001; η2  = 0.171; p < 0.001). CONCLUSION: Listening to music is effective for relieving acute procedural pain during the first post-operative tibial fracture dressing change. Music should be incorporated into the multimodal analgesia protocols for management of orthopedic postoperative wound care-related pain. SIGNIFICANCE: Patients with diaphyseal tibial fractures that listened to music before and during the wound dressing change showed less pain when compared to those who received the standardized pharmacologic analgesia alone.

The use of photobiomodulation therapy or LED and mineral trioxide aggregate improves the repair of complete tibial fractures treated with wire osteosynthesis in rodents.

The repair of large bone defects is lengthy and complex. Both biomaterials and phototherapy have been used to improve bone repair. We aimed to describe histologically the repair of tibial fractures treated by wiring (W), irradiated or not, with laser (λ780 nm, 70 mW, CW, spot area of 0.5 cm2, 20.4 J/cm2 (4 × 5.1 J/cm2, Twin Flex Evolution®, MM Optics, Sao Carlos, SP, Brazil) per session, 300 s, 142.8 J/cm2 per treatment) or LED (λ850 ± 10 nm, 150 mW, spot area of 0.5 cm2, 20.4 J/cm2 per session, 64 s, 142.8 J/cm2 per treatment, Fisioled®, MM Optics, Sao Carlos, Sao Paulo, Brazil) and associated or not to the use of mineral trioxide aggregate (MTA, Angelus®, Londrina, PR, Brazil). Inflammation was discrete on groups W and W + LEDPT and absent on the others. Phototherapy protocols started immediately before suturing and repeated at every other day for 15 days. Collagen deposition intense on groups W + LEDPT, W + BIO-MTA + LaserPT and W + BIO-MTA + LEDPT and discrete or moderate on the other groups. Reabsorption was discrete on groups W and W + LEDPT and absent on the other groups. Neoformation varied greatly between groups. Most groups were partial and moderately filed with new-formed bone (W, W + LaserPT, W + LEDPT, W + BIO-MTA + LEDPT). On groups W + BIO-MTA and W + BIO-MTA + LaserPT bone, neoformation was intense and complete. Our results are indicative that the association of MTA and PBMT (λ = 780 nm) improves the repair of complete tibial fracture treated with wire osteosynthesis in a rodent model more efficiently than LED (λ = 850 ± 10 nm).

A Modified 2-Stage Treatment for AO/OTA 43-C1 Pilon Fractures Accompanied by Distal Fibular and Posterior Lip of the Distal Tibia Fracture.

The management of pilon fractures remains challenging owing to the high-energy axial loading mechanism that produces comminution of the articular surface, displacement of tibia metaphysis, and severe soft tissue injury. How to preserve the vitality of soft tissue and achieve anatomic reduction has become a timely issue. We report and evaluate the effect of a modified staging treatment for AO Foundation/Orthopaedic Trauma Association (AO/OTA) 43C1 pilon fracture accompanied by distal fibular and posterior lip of the distal tibia fracture. We performed a modified 2-stage treatment of type C1 pilon fracture with distal fibular and posterior malleolar fractures. In the first stage, the posterolateral incision was used for simultaneous reduction of fibula and posterior malleolus, and the tibia was fixed with an external fixator. In the second stage, the external fixator was removed, and the medial malleolus and tibia were fixed after the edema of soft tissue had subsided. The following data were collected: Foot and Ankle Outcome Score (FAOS), American Orthopaedic Foot & Ankle Society (AOFAS) score, Short Form 36 (SF-36) score, Burwell-Charnley fracture reduction score, and postoperative complications. Twenty-seven patients were monitored for an average of 31.70 ± 7.38 months. The Burwell-Charnley fracture reduction scores had anatomic and fair ratings of 92.59%. SF-36 physical component score was 42.94 ± 12.47 and mental component score was 48.73 ± 9.79. Score data from the multiple scales of FAOS included pain, 88.79 ± 8.59; activities of daily living, 91.89 ± 7.50; quality of life, 90.26 ± 10.52; sports, 87.93 ± 11.64; and symptoms, 85.32 ± 8.65. The AOFAS ankle-hindfoot scores were 87.30 ± 13.45. Complications were reported in 5 patients (18.52%). Our study provides a good alternative to the existing protocol for type C1 pilon fractures with distal fibular and posterior lip of the distal tibia fracture and effectively reduces soft tissue complications.

Lower limb paediatric trauma with bone and soft tissue loss: Ortho-plastic management and outcome in a major trauma centre.

AIM: We examined the management and outcome of patients suffering complex paediatric lower limb injuries with bone and soft tissue loss. METHOD: Patients were identified from our prospective trauma database (2013-2018). Inclusion criteria were age (<18 years) and open lower-limb trauma. We assessed severity of soft tissue and/or bone loss, fracture complexity, surgical techniques and time to surgery. Paediatric quality of life and psychological trauma impact scores (HRQOL and CRIES), Ganga Hospital Injury Severity score (GHISS), union and complication rates were measured. RESULTS: We identified 32 patients aged between 4 and 17 years. Twenty-nine patients had open tibia fractures including 14 patients with bone loss, one patient had an open femur fracture, one patient an open talus fracture and one an open ankle fracture with dorsal degloving. Thirty injuries were classified intra-operatively as Gustilo IIIB (or equivalent) and two injuries as Gustilo IIIC. In 10 patients primary skin closure was achieved by acute shortening following segmental bone loss. Twenty-two patients required soft tissue coverage: 17 free vascularised flaps, two fascio-cutaneous flaps and three split skin grafts were used. Two patients required vascular repair. Soft tissue coverage was achieved within 72 hours in 26 patients (81%) and within a week in 30 patients (94%). The surgical techniques applied were: circular fine wire frame (19), monolateral external fixator (4) and open reduction internal fixation (8). Median follow up time was 18 (7-65) months. Paediatric quality of life scores were available in 30 patients (91%) with a median total score of 77.2 out of 100. The psychological trauma impact scores showed one in three patients was at risk of developing post-traumatic stress symptoms (PTSD). The GHISS scores ranged from 6-13. All fractures went on to unite over a median time of 3.8 (2-10) months. Three patients (9%) had major complications; two flap failures requiring revision, one femur non-union requiring revision fixation. CONCLUSION: Limb salvage and timely fracture union is possible in children with complex lower limb trauma. Early intervention providing adequate debridement, skeletal stabilisation and early soft-tissue cover including the option of free microvascular reconstruction in small children when required, delivers acceptable outcomes. A multidisciplinary team approach including clinical psychologists to address the psychological impact of trauma provides optimal holistic care for these children and adolescents. Therefore, treatment for these patients should only be performed in paediatric major trauma centres.

Raman spectroscopic study of the effect of the use of laser/LED phototherapy on the repair of complete tibial fracture treated with internal rigid fixation.

This study aimed to assess the repair of complete surgical tibial fractures fixed with internal rigid fixation (IRF) associated or not to the use of mineral trioxide aggregate (MTA) cement and treated or not with laser (λ = 780 nm, infrared) or LED (λ = 850 ±â€¯10 nm, infrared) lights, 142.8 J/cm2 per treatment, by means of Raman spectroscopy. Open surgical tibial fractures were created on 18 rabbits (6 groups of 3 animals per group, ∼8 months old) and fractures were fixed with IRF. Three groups were grafted with MTA. The groups of IRF and IRF + MTA that received laser or LED were irradiated every other day during 15 days. Animals were sacrificed after 30 days, being the tibia surgically removed. Raman spectra were collected via the probe at the defect site in five points, resulting in 15 spectra per group (90 spectra in the dataset). Spectra were collected at the same day to avoid changes in laser power and experimental setup. The ANOVA general linear model showed that the laser irradiation of tibial bone fractures fixed with IRF and grafted with MTA had significant influence in the content of phosphate (peak ∼960 cm-1) and carbonated (peak ∼1,070 cm-1) hydroxyapatites as well as collagen (peak 1,452 cm-1). Also, peaks of calcium carbonate (1,088 cm-1) were found in the groups grafted with MTA. Based on the Raman spectroscopic data collected in this study, MTA has been shown to improve the repair of complete tibial fractures treated with IRF, with an evident increase of collagen matrix synthesis, and development of a scaffold of hydroxyapatite-like calcium carbonate with subsequent deposition of phosphate hydroxyapatite.

Efficacy of Momiai in Tibia Fracture Repair: A Randomized Double-Blinded Placebo-Controlled Clinical Trial.

Objectives: Momiai ( shilajit, mummy, mumie, or mineral pitch) has been used traditionally in different medical systems for the treatment of a variety of ailments since hundreds of years ago. It is a natural substance found in different rocky parts of the world, formed by plants, mineral, and animal remains gradually. There is also worthwhile evidence supporting its oral use for bone repair in Persian medicine. The aim of this study was to evaluate the efficacy and safety of momiai in tibia fracture healing. Design: This study is a randomized double-blinded controlled trial. Settings/Location: Three different hospitals in Tehran, Iran. Subjects: Patients with age range of 18-60 years admitted due to new tibia fracture were enrolled after meeting the inclusion criteria. Interventions: The patients were divided into two groups randomly and received two 500 mg capsules of momiai or placebo for 28 days. Outcome measures: The process of bone healing was assessed by frequent X-ray radiographies and adverse effects were recorded. Results: Totally, 160 patients participated in the study either in two equal intervention or placebo groups. There was no significant difference between groups in terms of demographic and descriptive data. At the end of the study, the mean time of tibial bone union was 129 days in the experimental group, while it was 153 days in the placebo group (p < 0.049). There was no significant difference in the reported adverse effects between the two groups (p = 0.839). Conclusions: The current study showed that oral consumption of momiai after tibial shaft fracture surgery could be a promising option to reduce the healing time.

Autologous Iliac Bone Graft Compared with Biphasic Hydroxyapatite and Calcium Sulfate Cement for the Treatment of Bone Defects in Tibial Plateau Fractures: A Prospective, Randomized, Open-Label, Multicenter Study.

BACKGROUND: Bone-graft substitutes are commonly used for the augmentation of traumatic bone defects in tibial plateau fractures. However, their clinical performance compared with that of autologous bone-grafting, the gold standard in bone defect reconstruction, still remains under debate. This study investigates the differences in quality of life, pain, and radiographic outcomes in the treatment of tibial plateau fracture-associated bone defects with either autologous bone grafts or a bioresorbable hydroxyapatite and calcium sulfate cement (CERAMENT BONE VOID FILLER [CBVF]; BONESUPPORT). METHODS: In this study, 135 patients with acute depression and split-depression fractures of the proximal part of the tibia (OTA/AO types 41-B2 and 41-B3) were enrolled in a prospective, controlled, randomized, multicenter trial including 20 hospitals in Germany. Patients were randomized to receive either autologous iliac bone graft or CBVF for reconstruction of the bone defect. The primary outcome measures were the Short Form (SF)-12 version 2 Physical Component Summary (PCS) score at week 26 (the study was designed to show noninferiority of the CBVF with regard to the PCS with a prespecified margin of -5 points) and the pain level at 26 weeks postoperatively measured by a visual analog scale (VAS). The secondary outcomes were the SF-12 version 2 Mental Component Summary (MCS) and SF-12 PCS scores at weeks 1, 6, and 12 and bone-healing on radiographs. RESULTS: Age, sex, fixation methods, and fracture pattern were comparable in both groups. There were no significant differences (p > 0.05) in the SF-12 PCS or VAS scores at postoperative week 26. There was a significant reduction of blood loss (p = 0.007) and pain levels (p = 0.008) at postoperative day 1 in the CBVF group. The rates of fracture-healing, defect remodeling, and articular subsidence were not significantly different (p > 0.05) in both groups. CONCLUSIONS: Bioresorbable CBVF was noninferior to autologous bone graft with regard to both patient-reported and radiographic outcomes in tibial plateau fractures of OTA/AO types 41-B2 and 41-B3.

The Effect of Foot Massage on Pain Intensity and Anxiety in Patients Having Undergone a Tibial Shaft Fracture Surgery: A Randomized Clinical Trial.

OBJECTIVE: To determine the effect of massage therapy on pain intensity and anxiety in patients who have undergone tibial shaft fracture surgery. DESIGN: This study was a randomized clinical trial with a pre-post design. As the study included 2 treatment groups, it was a parallel study. SETTING: Khatam-Al-Anbia Hospital in Zahedan, Iran, between July and August 2017. PATIENTS: In all, 66 patients who underwent a tibial shaft fracture surgery were enrolled and randomly assigned to intervention and control groups (33 patients each). INTERVENTION: The intervention included a 10-minute foot massage (5 minutes per leg) using sweet almond oil, the most common lubricant used in massage therapy. MAIN OUTCOME MEASUREMENTS: Data were collected using pain numeric rating scale and Spielberger State-Trait Anxiety Inventory before and after intervention. RESULTS: After intervention, the mean scores for pain intensity, and anxiety in the intervention and control groups were 4.72 (0.97) and 5.72 (0.91), and 42.84 (6.50) and 58.36 (10.37), respectively. A significant difference was noted between the intervention and control groups concerning pain intensity and anxiety. CONCLUSIONS: The results indicated that massage therapy reduced pain intensity and anxiety in patients who underwent tibial shaft fracture surgery. Therefore, using massage as a noninvasive and acceptable intervention is suggested in orthopaedic surgery, especially after tibial shaft fracture surgeries. LEVEL OF EVIDENCE: Therapeutic Level I.
