Surgical Treatment of Olecranon Fractures Using a Medartis Screw-Locked H-Shaped Plate (Medartis Trilock Olecrane Plate) at the Moulins Yzeure Hospital Center (France)

Introduction: Olecranon fractures represent approximately 10% of upper limb fractures, orthopedic treatment is often doomed to failure and surgical treatment consists of fixing the fracture sites. Patients and Methods: This study retrospectively analyzed 130 patients, 90 men and 40 women, aged on average 48.7 ± 11.9 years (30 to 65) treated between 2018 and 2020 in the Orthopedics and trauma department at the Moulins-Yzeure hospital center, for olecranon fracture using the Medartis H-locked plate. The study aimed to evaluate the results of this surgical method, particularly with regard to postoperative complications. Results: Among the 130 patients, there were 90 men and 40 women, with an average age of 48.7 ± 11.9 years (30 to 65). 50% of all patients were aged over 51 years. The plate used was standard, the same for the 130 patients with the same operating technique. The left side was more affected at 53.8%, the dominant side was less affected at 46%;the majority of patients had been temporarily immobilized with a posterior cast splint before surgery. The average time between trauma and operation was 9 days with a minimum time of 1 day and a maximum of 30 days. At a maximum follow-up of 2 years postoperatively, all patients reported satisfactory results with a return to their previous activities within 60 days after surgery. Conclusion: Medartis H-locked plate osteosynthesis is a reliable solution for the surgical treatment of olecranon fractures.

Treatment of a femoral neck fracture combined with ipsilateral femoral head and intertrochanteric fractures: A case report

BACKGROUND This article presents a rare case of a complex hip fracture involving the ipsilateral femoral neck,trochanter,and femoral head,that was accompanied by hip dislocation.Currently,there is no established standard treatment method for this specific type of fracture.Therefore,it is crucial to comprehensively consider factors such as patient age,fracture type,and degree of displacement to achieve a successful outcome.CASE SUMMARY A 38-year-old man sustained a comminuted fracture of his right hip as a result of a car accident.The injuries included a fracture of the femoral head,a fracture of the femoral neck,an intertrochanteric fracture of the femur,and a posterior dislocation of the hip on the same side.We opted for a treatment approach combining the use of a proximal femoral locking plate,cannulated screws,and Kirschner wires.Following the surgery,we developed an individualized rehabil-itation program to restore patient limb function.CONCLUSION For this complex fracture,we selected appropriate internal fixation and for-mulated individualized rehabilitation,which ultimately achieved good results.

Locking plates for distal fibula fractures in young and elderly patients:A retrospective study

BACKGROUND Ankle fractures are common injuries in the young and elderly populations.To prevent post-traumatic arthritis,an anatomic reconstruction of the ankle structure is mandatory.Open reduction and internal fixation is the treatment of choice among orthopaedics.Conventional plates allow stability of the fracture if bone quality is present.Locking plates might offer an advantage for the treatment of lateral malleolar fracture in patients with comminution,severe instability,distal fractures,or osteoporotic bone.Our hospital introduced a new locking plate for fracture of the distal fibula.AIM To evaluate locking plates in terms of outcomes and complications in young and elderly patients.METHODS We retrospectively reviewed a total of 67 patients treated for displaced distal fibula fractures.Demographic data,number of comorbidities,use of inter fragmentary screw,complication,time of fracture healing,partial or full weight bearing,and reoperation were recorded for all patients.Clinical outcome was assessed by the American Orthopedic Foot and Ankle Society clinical scoring system.Radiographs were obtained at 4,8,12,16,20,and 24 wk until radiographic union was obtained.RESULTS All patients displayed complete bony union on radiographic assessment,and no patients developed any serious complications.We observed two superficial infections,one delayed wound healing,and two plate intolerances.Significant differences were observed between the two age groups in terms of radiographic healing(11.9 wk in younger patients vs 13.7 wk in older patients;P=0.011)and in the American Orthopedic Foot and Ankle Society score at 6 mo after surgery(88.2 in younger patients vs 86.0 in older patients;P=0.001)and at 12 mo after surgery(92.6 in younger patients vs 90.0 in older patients;P=0.000).CONCLUSION Locking plates provide a stable and rigid fixation in multifragmentary and comminuted fractures or in the presence of poor bone quality.

Fixation of Calcaneal Tuberosity Beavis II Fracture in Elderly Patients Using Locking Plate Combined with Tension Screw

Background:Calcaneus is the largest bone of foot and the main load-bearing structure of heel.The incidence of simple calcaneal tubercle avulsion fracture is low,accounting for about 1%to 3%of all calcaneal fractures.Beavis II fracture has large bone fracture,obvious displacement,obvious soft tissue irritation,and often leads to skin necrosis.It needs surgical treatment,reduction and fixation as soon as possible.Although open reduction and tension screw internal fixation is used for Beavis II calcaneal tubercle fracture,but the failure rate is more common.Methods:This study retrospectively analyzed the surgical treatment of calcaneal tubercle Beavis II fracture over 55 years old in our hospital from January 2013 to January 2019.The patients were treated with tension screw combined with locking plate,and followed up and analyzed.Results:12 patients in this group were followed up for 12 to 36 months(mean 20 months).After operation,the fracture healed smoothly in all patients,the healing time was 8 to 12 weeks(mean 10.7 weeks),and there were no complications such as poor incision healing,fracture displacement,internal fixation loosening,fracture and so on.When the patients were followed up 18 weeks after operation,the AOFAS score was 47 to 100,with an average of 91.1,of which 8 cases were excellent,3 good and 1 poor,with an excellent and good rate of 91.7%.Conclusion:Our hospital has been treated with tension screw combined with locking plate,fixed firmly,can early functional exercise,achieved good results.

Construction monitoring of lock head base plate using distributed optical fibre sensing technique

The concrete hydration heat release process of the base plate is monitored using Roman optical time domain reflectometry（ROTDR） sensing sensors. The monitoring data shows that the internal maximum temperature of the base plate is about 54 ℃ after the concrete was cured for 120 h. The fiber Bragg grating （FBG） temperature sensors are adopted to measure the surface temperature of the concrete and the temperature results are used to compensate the data measured by the pulse-prepump Brillouin optical time-domain analyzer （PPP-BOTDA） to obtain the real concrete surface strain of the base plate. The monitoring data is analyzed to obtain a clear understanding of the strain state of the base plate under the effect of concrete hydration heat release. The monitoring results demonstrate the potential of distributed optical fibre sensing techniques as a powerful tool in real-time construction monitoring, and also provide an important insight into the design, construction and maintenance of large hydraulic structures.

Locking compression plate+T-type steel plate for postoperative weight bearing and functional recovery in complex tibial plateau fractures

Complex tibial plateau fractures can seriously affect quality of life and physical and mental health of patients.The anatomical relationship between the proximal tibial bone and soft tissue is complex,resulting in different types of tibial plateau fractures.Violent trauma can lead to displaced fracture,serious soft tissue injury,and potentially,dislocation of the knee joint.Therefore,tibial plateau fractures are extremely unstable.AIM To assess the use of locking compression plate(LCP)+T-type steel plate for postoperative weight bearing and functional recovery of complex tibial plateau fractures.METHODS Ninety-seven patients with complex tibial plateau fractures who underwent surgery at our hospital were selected for retrospective study.Forty-nine patients had been treated with LCP+T-type steel plate limited internal fixation(study group),and 48 patients with bilateral ordinary steel plate support(control group).The operation process index,postoperative rehabilitation related index,Rasmussen score of the knee joint,tibial plateau varus angle(TPA),tibial plateau retroversion angle(PA),and surgical complications of the two groups were compared.RESULTS The operation time and intraoperative bone graft volume in the study group were lower than those in the control group(P<0.05).There were no significant differences in surgical bleeding,anterior external incision length,postoperative drainage,hospital stay duration,and fracture healing time between the groups(P>0.05).There was no significant difference in the TPA and PA angle between the groups immediately and 18 mo after surgery(P>0.05).At 12 mo after surgery,the Rasmussen scale score was higher in the study group than in the control group(P<0.05).There was no significant difference in the Rasmussen scale score at 18 mo after surgery,and the radiology score at 12 and 18 mo after surgery,between the two groups(P>0.05).The postoperative complication rate in the study group(3.77%)was lower than that in the control group(15.09%;P<0.05).CONCLUSION LCP+T-type steel plate internal fixation has advantages in terms of minimizing trauma and enabling early postoperative functional exercise,promoting functional recovery and lower limb weight-bearing,and reducing postoperative complications.

Biomechanical Comparison of Gourd-shaped LCP versus LCP for Fixation of Comminuted Tibial Shaft Fracture

The purpose of this study was to compare monotonic biomechanical properties of gourd-shaped LCP fixation with LCP fixation of human tibial shaft in gap fracture mode. Twenty paired fresh cadaveric human tibias were randomly divided into 4 groups （5 pairs each）： （1） axial loading sin- gle cycle to failure testing, （2） torsion single cycle to failure testing, （3） 4-point bending single cycle to failure testing, and （4） dynamic 4-point bending testing. A 7-hole 4.5 mm gourd-shaped LCP was se- cured on the anteromedial surface of 1 randomly selected bone from each pair, respectively, using 6 locking screws in the 1st, 2nd, 3rd, 5th, 6th and 7th hole with the middle hole unfilled and just located at the mid-diaphysis of the tibia. A 7-hole 4.5 mm LCP was secured on the other bone with the same method. Standard AO/ASIF techniques were used. After fixation finished, a 10 mm gap in the mid-diaphysis of tibia was created, centrally located at the unfilled hole. The axial, torsional, and bending stiffness and failure strengths were calculated from the collected data in static testings and statisti- cally compared using paired Student＇s t-test. The 4-point bending fatigue lives of the two constructs were calculated from the dynamic testing data and also statistically compared using paired Student＇s t-test. Failure modes were recorded and visually analyzed. P〈0.05 was considered significant. Results showed that the axial, torsional and bending stiffness of gourd-shaped LCP construct was greater （4%, 19%, 12%, respectively, P〈0.05） than that of the LCP construct, and the axial, torsional and bending failure strengths of gourd-shaped LCP construct were stronger （10%, 46%, 29%, respectively, P〈0.05） than those of the LCP construct. Both constructs failed as a result of plate plastic torsional deformation. After axial loading and 4-point bending testings, LCP failed in term of an obvious deformation of bent apex just at the unfilled plate hole, while the gourd-shaped LCP failed in term of a deformation of bent arc between the 3rd and 5th holes, which indicated a more consistent stress distribution on gourd-shaped LCP. Fatigue life of gourd-shaped LCP construct was significantly greater than LCP construct （153 836±2 228 vs. 132 471±6 460 cycles, P〈0.01）. All constructs failed as a result of fracture of the plate through the compression hole of the unfilled combination screw hole. The biomechanical testing showed that gourd-shaped LCP can provide greater stiffness and strength, and longer fatigue life than LCP. The gourd-shaped LCP may be more advantageous mechanically and may reduce the plate breakage rate clinically.

Endosteal Fibular Strut Graft with Proximal Humeral Locking Plate in Delayed and Neglected Fractures of the Proximal Humerus

Purpose: The purpose of this study was to define a treatment protocol in which a non-vascularized endosteal fibular strut graft, a corticocancellous grafts and a locking plate construct are used for stabilization of the delayed and neglected proximal humerus fractures and to report its outcome. Patients & Methods: Eleven patients (6 females and 5 males) with delayed, neglected proximal humerus fractures were included in this study, conducted between March 2015 and December 2019. Average age of the patients was 57 years (range: 41 to 67 yrs). All patients were treated with the debridement, decortication and shingling of the bone at the site of the fracture followed by using an endosteal fibular strut graft, corticocancellous bone grafts and stabilization with locking plate. The patients were followed up for a mean time of 16.3 months (range: 13 to 40 months). The patient outcomes were evaluated using the Disabilities of the Arm, Shoulder, and Hand Questionnaire, and the modified scoring system of Constant and Murley. Results: Union at the fracture site was achieved in all patients at a mean of 8.5 months (range: 6 to 11 months). The DASH score improved from an average pre-operative score of 71.1 (range: 64 to 78) to an average post-operative score of 25.2 (range: 21 to 35) at the final follow-up. Albeit with a small sample size of n = 11, this difference was found to be statistically significant (p < 0.05). The CM score improved from an average pre-operative score of 33.2 (range: 20 to 48) to an average post-operative score of 66.8 (range: 59 to 72) at the final follow-up. This difference was also found to be statistically significant in this patient cohort (p < 0.05). The results were excellent in 3 patients, good in 6 and moderate in 2. Conclusions: An endosteal fibular strut, subperiosteally placed cortico-cancellous grafts with a locking plate fixation helps in biological healing of neglected fractures of proximal humerus.

Complex proximal femoral fracture in a young patient followed up for 3 years: A case report

BACKGROUND Ipsilateral femoral neck and intertrochanteric fractures in young patients are extremely rare,and there is no reference for fracture classification and treatment options.CASE SUMMARY We report a 27-year-old male patient who sustained ipsilateral femoral neck and intertrochanteric fractures and was treated with a proximal femoral locking compression plate(PFLCP).The literature on these fractures was also reviewed.At the last follow-up three years after surgery,the patient had no obvious pain in the hip,and the range of motion in the hip joint was slightly limited,but met the normal life and work needs.There were no complications such as necrosis of the femoral head.CONCLUSION The PFLCP can be used to treat these complex proximal femoral fractures,and selection should be based on the patient's specific fractures.

A New Intramedulary Locking Plate for the Osteotomy of the V. Metatarsal in the Correction of the Tailors Bunion. Midterm Results of 21 Patients

Background: Since we are very successful in the operation of hallux valgus using a transverse sub-capital osteotomy fixated with an intramedullary angle-stable locking plate, and a tailors bunion is understood as a reversed hallux valgus, we have applied the operation also for such indication. Method: The osteotomy was carried out at a straight V. metatarsal subcapitally, and in case of an outwardly curved V. metatarsal at the bending location. The intramedullary plates are available in different designs and the plate and screws disappear completely in the bone, so the soft tissues are not disturbed. The head of the plate is either straight or curved in order to shift the distal fragment sufficiently. Results: 26 patients were operated within a period of 5 years (2008-2012). 21 patients were followed up after an average of 34.4 months. The IM angle IV/V could be improved by an average of 11.76 to an average of 4.10. This is a highliy significant pre- to postoperative difference of 7.66 (t = 15.07, p < 0.001). The AOFAS score was improved by an average of 42.24 points from 55.76 points preoperatively to 98.00 points postoperative. There was no pseudo-arthrosis and no wound healing impairment. All patients were either satisfied or very satisfied with the surgery. Conclusion: This method does not have the disadvantages of the other common operations of the Tailors bunion and is applied now as a standard method in this deformity.

Dynamic External Fixator Combined with Volar Locking Plate Fixation for the Treatment of AO Type C3 Distal Radius Fractures

Background: AO type C3 distal radius fracture (DRF) is the most difficult-to-treat fracture type because of a tendency to shorten and collapse. The purpose of this study is to investigate the clinical and radiographic outcomes of comminuted intra-articular DRFs treated with a dynamic external fixator combined with a volar locking plate (VLP). Methods: Eleven patients (mean age, 61 years) with comminuted intra-articular DRFs were treated with a dynamic type of external fixator combined with a VLP. Following reduction and fixation with a VLP, the dynamic external fixator was applied and the distal ball joint of the fixator was aligned with the lunate-capitate line. The ball joint was unlocked approximately 2 weeks after surgery to allow wrist mobilization. The fixator was removed 3 - 6 weeks (mean, 5 weeks) after surgery. Consequently, clinical and radiographic assessments were carried out at the final follow-up. Results: At the final follow-up, the mean range values of wrist extension and flexion were 76&deg;and 64&deg;, respectively. Compared with the contralateral side, the mean grip strength was 84%. The mean Modified Mayo Wrist Score and the Disabilities of the Arm, Shoulder and Hand score were 88 and 9, respectively. No significant differences in the radiographic parameters exist between after surgery and final follow-up. Conclusions: This study indicated that the dynamic wrist fixator combined with a VLP is effective for the treatment of AO type C3 DRFs.

Irreducible Posterior Hip Dislocation with Associated Isolated Comminuted Greater Trochanter Avulsion Fracture Treated with Universal Locking Trochanteric Stabilization Plate: A Rare Combination of Hip Injury

Posterior hip dislocation with greater trochanter fracture is an uncommon injury pattern in the acute trauma patient. Frequently associated injury includes a combination of hip dislocation with posterior wall of acetabulum, head of femur fracture, intertrochanteric fracture and even the most severe type of combined acetabular fracture. We report a 42-year-old man post traumatic bilateral hip injuries with irreducible posterior hip dislocation and associated isolated greater trochanteric fracture successfully managed with open reduction and fixation of greater trochanter with universal locking trochanteric stabilization plate.

Postoperative Fracture Healing Effects of Locking Compression Plate for the Treatment of Limb Fractures

Objectives To study the effects of applying locking compression plates in the treatment of patients with limb fractures on postoperative fracture healing.Methods:115 patients with limb fractures who were treated in our hospital from November 2019 to November 2020 were selected.In order to study the effective treatment method,the random-number table method was used in this study to divide the patients into two groups,namely the experimental group and the control group,and the locking compression plate treatment method and the pure plate and screw internal fixation treatment method were administered respectively to study their clinical application effects.Results:Compared with the control group,patients in the experimental group had a lower incidence of complications,shorter hospitalizations and shorter recovery time.Meanwhile,the experimental group had a better quality of recovery,and all data were significantly different from those of the control group,P<0.05,the intervention effect of the experimental group was better.Conclusion:The application of the locking compression plate in the treatment of patients with limb fractures is more conducive to promoting the postoperative healing of the patients'fractures,reducing the incidence of postoperative complications,and promoting the rapid recovery of patients,which has positive significance for clinical development.

Locking plate fixation combined with iliac crest bone autologous graft for proximal humerus comminuted fracture

Background Although the use of an intramedullary fibular allograft together with locking plate fixation can provide additional medial support and prevent varus malalignment in displaced proximal humeral fractures with promising results,the fibular autograft donor site often sustains significant trauma and cannot restore the articular surface of comminuted fractures.The aim of this study was to evaluate the clinical and radiographic outcomes of a locking plate and crest bone autologous graft for treating proximal humerus comminuted fractures.Methods We assessed the functional outcomes and complication rates in 40 patients with proximal humerus comminuted fractures.Eighteen patients were treated with a locking plate and an autologous crest bone graft （experimental group）,and 22 were treated with only the locking plate and no bone graft （control group）.Postoperative assessments included radiographic imaging,range of motion analysis,pain level based on the visual analogue scale （VAS）,and the SF-36 （Short Form （36） Health Survey）,as well as whether patients could retum to their previous occupation.Results All fractures healed both clinically and radiologically in the experimental group.There was no more than 2 mm collapse of the humeral head,and no osteonecrosis or screw penetration of the articular surface.In contrast,two patients had a nonunion in the control group,and they eventually accepted total shoulder replacements.The average time from surgery to radiographic union was significantly shorter in the experimental group （（4.66±1.63） months） compared with the control group （（5.98±1.57） months） （P ＜0.05）.For the experimental versus controls groups,the mean shoulder active flexion （148.00±18.59 vs.121.73±17.20） degrees,extension （49.00±2.22 vs.42.06±2.06） degrees,internal rotation （45.00±5.61 vs.35.00±3.55）degrees,external rotation （64.00±9.17 vs.52.14±5.73）degrees,and abduction （138.00±28.78 vs.105.95±15.66） degrees were all significantly higher （all P ＜0.001）.The median SF-36 in the experimental group （（88.00±5.71） points） was significantly higher than that of the control group （（69.45±9.45） points; P ＜0.001）.The median VAS pain level （mean rank,10.50） in the experimental group was lower than that （mean rank,47.19） of the control group （P ＜0.001）.All but one patient （17 of 18,94.4％） in the experimental group returned to their previous activities or occupations,and that one patient changed to a different occupation because of slight restrictions to activities.On the other hand,four patients could not return to their previous activities or occupations in the control group.Conclusion Locking plate fixation combined with an iliac crest bone graft is an effective technique for treating proximal humerus comminuted fractures.

Complications of the locking plate for displaced proximal humeral fractures

Background Although the locking plate has become popular for treating displaced proximal humeral fractures in recent years, the complications of this method are still underestimated. We tried to evaluate the factors that have an influence on the complications experienced after proximal humeral fractures fixed by locking plates and compare the results from patients having complications with those having no complications. Methods From September 2004 to September 2007, 92 out of 111 displaced proximal humeral fractures treated by open reduction and internal fixation with a locking plate were available for follow-up, with an average time of 15.2 months （12-36 months）. The range of motion, Visual Analog Score （VAS） for pain, American Shoulder and Elbow Surgeons＇ Form （ASES）, Constant-Murley, University of California-Los Angles scoring system （UCLA） score, and Simple Shoulder Test （SST） for function evaluation was all recorded at the latest follow-up. The results from patients with complications were evaluated according to the indices listed above and compared with those patients without any complications. Results There were 17 patients with complications, an 18.5% complication rate. Among them, the forward flexion, external rotation and internal rotation were 139.1°±24.3°, 24.1°±19.6°, and up to T10 level on average. The mean VAS score was 1.0±1.1, the ASES score was 82.9±13.8, the Constant 82.1±11.8, the UCLA 28.5±4.1 and the mean SST 9.5 on average. There was no significant difference of complication rate among different age, sex, and injured side, fresh or delayed fracture, combined with other injury or not groups. Compared with the group without complications, patients with complications showed significantly less external rotation and lower Constant-Murley and UCLA functional scores （P 〈0.05）. A significant difference in results was seen between patients with complications and those without complications. Conclusion The indication control and appropriate surgical technique were important while performing the locking plate fixation for proximal humeral fractures.

Outcome of distal end clavicle fractures treated with locking plates

Purpose： Fractures of the lateral end of the clavicle are relatively uncommon. These fractures are unstable due to the various deforming forces which act on the fragments as well as the small distal fracture fragment. At most times the deforming forces are not taken into consideration, and the fracture is not fixed securely. In this study, we assessed a fixation technique using the precontoured locking plates to find out whether it provided a stable fixation with good functional outcome. Methods： Totally, 32 patients with lateral end clavicle fracture （Neer＇s Type ll） were included in the study. After the informed consent and preoperative investigations were obtained, open reduction and intemal fixation was done using a 3.5 mm precontoured superior locking plate with lateral extension under general anesthesia. Postoperative X-rays were done on day I and every 6 weeks after operation, until radiological union was achieved. The postoperative pain was assessed using Visual Analogue Scale （VAS） on postoperative days 1, 2 and 10. Postoperatively arm pouch sling was given for 2 weeks followed by active mobilization. Patients were asked to do their daily routine work and avoid lifting heavy weights. The functional outcome was assessed at the end of 2nd and 6th months with the help of Disabilities of the Arm, Shoulder and Hand （DASH} scoring. Results： There were no intraoperative complications in the procedure. The mean VAS score on post- operative day 1 was found to be 5 which decreased to 3 on day 2 and 0 on day 10. The mean DASH score was calculated as 11.63 at the end of postoperative month 2 and then 4.6 at the end of month 6. There was one case of malunion in whom the overhead abduction was restricted but was not painful and was managed conservatively. Conclusion： The precontoured locking plates with lateral extension may be a good method to fix the fractures of the lateral end clavicle, which provide a stable fixation with good functional outcome with very few instances of stiffness and decreased range of motion of the shoulder with the hook plates and failure of fixation in screw and K-wire fixations. It may well be the answer to the fixation questions of the lateral clavicle fractures, although larger comparative studies between the surgical treatment methods are required to confirm the same.

Treatment of distal clavicle fracture with distal radius volar locking compression plate

Objective: To observe the early clinical outcomes of the internal fixation with distal radius volar locking compression plate (LCP) in treatment of distal clavicle fracture.Methods: Six patients with unilateral distal clavicle fractures, identified as type Ⅱ according to Neer classification system, including 4 males and 2 females, were treated with open reduction and internal fixation using a distal radius volar LCP. Bone union was evaluated by routine X-ray radiography, and shoulder joint function were assessed by Constant score system.Results: All fractures achieved bone union at 6 to 8 weeks postoperatively, and Constant scores ranged from 95 to 100 at the postoperative 10 to 12 weeks.Conclusion: Fixation of distal clavicle fracture with distal radius volar LCP demonstrates excellent effects of bone union with rarely early complications, thus providing a new technique to treat distal clavicle fracture.

Expanding the horizons of clinical applications of proximal humerus locking plates in the lower extremities:A technical note

Pre-contoured anatomical locking plates were designed to address the clinical need of fixing small epiphyseal segments with a larger number of screws.Those plates match the contour and shape of a variety of bones allowing for optimal buttress properties.The aim of this manuscript is to highlight the benefits of applying proximal humerus locking plates in the fixation of lower extremity bones.Although designed for the proximal humerus,the low-profile plate shape and anatomic contour also provides versatile use in certain areas of the lower extremity.This technical narrative highlights the versatile and reliable use of this plate for other anatomical areas than the one to which it has been originally conceived.
