Treatment of Klammer type Ⅲ posterior pilon fracture via the posterolateral combined posteromedial approach / 中华创伤骨科杂志

Objective:To investigate the therapeutic effects of internal fixation via the posterolateral combined posteromedial approach in the treatment of posterior pilon fracture (Klammer type Ⅲ).Methods:A retrospective study was performed to analyze the 69 posterior pilon fractures (Klammer type Ⅲ) which had been treated by internal fixation with hollow screws or a buttress plate at Department of Orthopaedic Trauma, Yantai Shan Hospital from January 2015 to January 2020. There were 36 males and 33 females with an age of (45.3±10.0) years and duration from injury to surgery of (6.0±1.5) d. They were assigned into 2 groups according to different surgical approaches. The observation group (41 cases) was treated through the posterolateral combined posteromedial approach while the control group (28 cases) through the posterolateral approach alone. The therapeutic effects were evaluated by comparing the 2 groups in terms of incision length, intraoperative bleeding, operation time, fracture union time, fracture reduction (evaluated by the Burrwell-Charnley radiological score), the ankle-hindfoot score of American Orthopaedic Foot and Ankle Society (AOFAS) and complications.Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). All the 69 cases were followed up for (16.9±4.0) months, revealing primary healing of all the incisions and no vascular injury or wound infection. The incision length [(11.2±1.8) cm] and operation time [(76.0±6.6) min] in the observation group were significantly shorter than those in the control group [(12.4±1.9) cm and (79.7±6.8) min], the excellent and good rate of reduction in the observation group (97.6%, 40/41) was significantly higher than that in the control group (89.3%, 25/28), and the ankle-hindfoot scores of AOFAS at 1, 3 and 12 months after operation in the observation group [(78.4±5.6), (79.5±2.8) and (86.9±2.1)] were significantly higher than those in the control group [(75.2±5.5), (78.0±3.2) and (85.8±2.3)] (all P<0.05). There was no significant difference in the intraoperative bleeding between the 2 groups ( P>0.05). In the control group, 2 patients developed numbness in the dorsum of foot, which gradually disappeared after 3 months of treatment, but no other complications like persistent pain or flexor contracture within 1 year after operation. Conclusion:In the treatment of Klammer type Ⅲ posterior pilon fracture, the posterolateral combined posteromedial approach can result in satisfactory therapeutic effects, because the surgical approach can fully expose the fracture and facilitate better reduction.

Analysis of the efficacy of a modified posteromedial approach for Klammer III posterior Pilon fractures / 中华创伤杂志(英文版)

PURPOSE@#To analyze the curative effect and technical points of a modified posteromedial approach in the treatment of Klammer III posterior Pilon fracture.@*METHODS@#A retrospective analysis of patients with Klammer III posterior Pilon fractures were conducted in our department from January 2018 to December 2019. Before the surgery, the patients were fully relieved of swelling and pain, and a comprehensive examination was carried out. The posteromedial approach exposed the posterior and medial fracture block of the distal tibia. According to the fracture of external malleolus, it is determined whether to combine a lateral incision and protect tendons and vascular nerves by a retractor, and then perform a fracture reduction and internal fixation. Postoperatively, the patients were treated with analgesia, detumescence, anticoagulation and rehabilitation exercise. The American orthopaedic foot and ankle society (AOFAS) score and visual analogue score were recorded at regular follow-up after surgery. A t-test was used for the comparison of the preoperative and final AOFAS score.@*RESULTS@#There were 7 male and 13 female (n = 20) included in the study, aged 22 to 88 years (average age 54.2 years). The injury mechanisms were falling from a height (n = 7), traffic accident (n = 6), walking injury (n = 2) and heavy injury (n = 5). The postoperative follow-up duration was 12-24 months (mean 16.95 months). The AOFAS score of the 20 patients before and after surgery were compared. The preoperative AOFAS score was 38.90 ± 3.91, and the final AOFAS score was 80.55 ± 4.20, (p < 0.001). The mean final visual analogue scores at rest, active and weight-bearing walking were 0.30, 0.85 and 1.70, respectively. One patient reported poor postoperative wound healing and required a return to hospital for debridement and anti-infection treatment.@*CONCLUSION@#In the treatment of Klammer III posterior Pilon fractures, the modified posteromedial approach can fully expose the fracture block and the collapsed articular surface of the medial malleolus, achieve good reduction and internal fixation with limited injury of the tendon and vascular nerves, and have a better prognosis.

Role of posteromedial plating in condylar fractures of Tibia in adults

Background: The purpose of this study was to evaluate role of Posteromedial Plating in condylar fractures of Tibia, especially patients with posterior tibial shear fractures. Materials and methods: This prospective study included 12 patients with mean age 40 years (range 30 to 50 years) who sustained high velocity posterior tibial plateau fracture-subluxations with/ without associated Bicondylar fractures (Moore I & II Types, Schatzker’s Groups – IV, V and VI). Surgical management included stabilisation plating through a posteromedial/ posterior approach and additional postero lateral or antero lateral approach as needed. The patients were followed up at six week, three month, six month and one year postoperatively and assessed using Oxford Knee Score and Lyshom Score. Results: The mean OKS score was 40 (range 36 to 44) at the end of one year. The main clinical measures were early post-operative non weight bearing ROM, post-operative complication and functional outcome. The time to full weight bearing, the rate of post-operative complications and functional outcome was significantly better as evident by over 94 % showing good to excellent OKS and Lyshom scores. Conclusion: A posterior/ postero medial approach for posterior tibial plateau shear fractures (which are otherwise irreducible by conventional approaches) and buttress/ antiglide plate are usually needed to reduce the fractures anatomically, achieving absolute stability and mobilize early NWB, ROM of the knee joint to optimize the functional outcomes and minimize the complications, without the need for revision surgery.

Tibial plateau posterior column fractures treated via the posteromedial approach dissecting the gastrocnemius medial head / 中华创伤骨科杂志

Objective To discuss the treatment of tibial plateau posterior column fractures via the posteromedial approach which dissects the medial head of the gastrocnemius muscle.Methods From July 2013 to September 2016,7 patients were treated at Department of Orthopaedics and Trauma,The First Affiliated Hospital to Dalian Medical University by surgery via the posteromedial approach dissecting the medial head of the gastrocnemius muscle for tibial plateau posterior column fractures.They were 6 men and one woman,aged from 38 to 61 years (49.3 years on average).According to AO/OTA classification,4 cases belonged to type 41-B3.3,one to type 41-B3.1,one to type 41-C3.3 and one to type 41-C3.1.According to the three-column classification,3 cases were categorized into three-column fracture,2 cases into fracture of both medial and posterior columns,and 2 cases into simple posterior column fracture.Of the posterior column fractures,5 had the medial posterior column split and the lateral column collapsed,and 2 had the medial posterior column split.According to Schatzker classification,5 cases were categorized into type Ⅳ,one into type Ⅴ and one into type Ⅵ.Fracture reduction was assessed according to the Rasmussen criteria postoperation.The knee function was assessed at final follow-ups using The Hospital for Special Surgery (HSS) scoring system.The postoperative complications were documented.Results Insertion rupture of the posterior cruciate ligament was found in one case,lateral meniscus injury in 2 cases,and tibial external dislocation combined with bone fragment incarceration into the lateral femoral condyle in one case.All the lesions were repaired.All the incisions were healed at the first stage.No major neurovascular injuries were found.The 7 patients were followed up for 8 to 12 months (mean,11.4 months).Bony union was achieved in all after 12 to 16 weeks (mean,14.3 weeks).The postoperative Rasmussen reduction scores averaged 17.7 points.The average tibial plateau tilt angle was 9.5°postoperatively and 10.8° at final follow-ups;the average tibial plateau varus angle was 86.7° postoperatively and 87.3° at final follow-ups.The HSS knee scores at final follow-ups averaged 91.4 points.No significant reduction loss,implants loosening,infection or malunion was observed at final follow-ups.Conclusion The posterior medial approach which dissects the medial head of the gastrocnemius muscle is a safe and practical one for treatment of tibial plateau posterior column fractures,because it can well expose the posterior column of the entire tibial plateau so that is beneficial to the anatomical reduction of the fracture and placement of implants,leading to fine short-term curative effect.

Abordaje posteromedial y colocación de placa en fractura de meseta tibial con fragmento posterior / Posteromedial approach and plating for a tibial plateau fracture with a posterior fragment

Antecedentes: Las fracturas de meseta tibial representan 1% de todas las fracturas, de éste, 10% corresponde a la meseta medial. El espectro de lesiones va desde fracturas no desplazadas hasta fracturas devastadoras del platillo tibial completo que requieren manejo quirúrgico extenso. Literatura en cirugía ortopédica sugiere que los resultados funcionales y radiográficos positivos dependen del tipo de abordaje, la calidad de la reducción y el tipo de implante utilizado. Material y métodos: Reporte de casos ambispectivo; comprendió de siete pacientes con fractura de meseta tibial medial y fragmento posterior a los cuales se les colocó placa posterior luego del abordaje posteromedial en un período de tiempo entre Agosto 2012 y Agosto 2013. Se utilizó la clasificación de Khan para estadificar la fractura. Se evaluó el resultado funcional y radiográfico mediante escala de Rasmussen. Se realizó estadística de frecuencias y descriptiva. Resultados: Se midió el dolor utilizando la escala visual análoga (EVA), encontrando un mínimo de dos puntos y un máximo de cuatro puntos. La flexión osciló entre 40º y 110º con un déficit de extensión mínimo de 15º y máximo de 40º. La deformidad en varo se presentó en cuatro sujetos, la deformidad en valgo en tres. Conclusiones: El abordaje posteromedial y la colocación de placa posterior en fracturas de meseta tibial presentan arcos de movilidad adecuados para la función, así como un bajo grado de dolor. La angulación en varo se presenta en pacientes con fractura de ambos platillos tibiales.

Background: Tibial plateau fractures account for 1% of all fractures. Ten percent of them involve the medial plateau. The spectrum of lesions ranges from undisplaced fractures to devastating fractures involving the entire tibial plateau, which warrant extensive surgical management. The orthopedic surgery literature suggests that positive functional and radiographic results depend on the type of approach, the quality of reduction and the type of implant used. Material and methods: Ambispective case report: seven patients were enrolled, with fracture of the medial tibial plateau and a posterior fragment. A posterior plate was placed after a posteromedial approach, between August 2012 and August 2013. Fractures were staged according to the Khan classification. Functional and radiographic results were assessed using the Rasmussen scale. Frequency and descriptive statistics were used. Results: Pain was measured using a visual analog scale (VAS), with scores ranging from two to four. Flexion ranged between 40º and 110º, with a minimum extension deficit of 15º and a maximum of 40º. Four subjects had varus deformity, three had valgus deformity. Conclusions: The posteromedial approach and placement of a posterior plate for tibial plateau fractures results in ranges of motion that permit an appropriate function and involve mild pain. Varus angulation occurs in patients with bilateral tibial plateau fractures.

Debridement Arthroplasty using Posteromedial Approach in Elbow Joint with Pain and Bony Limitation of Motion

PURPOSE: This study evaluated the clinical outcomes of debridement arthroplasty using the posteromedial approach in elbow joints with pain and bony limitation of motion. MATERIALS AND METHODS: This study involved 16 elbows in 16 patients with pain and bony limitation of motion, which were treated by debridement arthroplasty using the posteromedial approach from March 2005 to March 2008. The mean follow up period was 27.6 (13~52) months. The clinical outcomes were analyzed using the Visual Analogue Scale(VAS) for pain scale, the preoperative and postoperative range of motion and the Mayo Elbow Performance Scores(MEPS). RESULTS: The VAS was decreased significantly from a preoperative mean of 4.5 to a postoperative mean 1.1 (p<0.001). The average arc of motion improved significantly from 61.6 (0~90)degrees preoperatively to 109.4 (80-120)degrees postoperatively (p<0.001). The MEPS also improved significantly from 59.4 to 85.6 postoperatively (p<0.001). There were no complications, such as hematoma and elbow instability. CONCLUSION: Debridement arthroplasty using the posteromedial approach is a useful surgical procedure in the elbow joint with pain and bony limitation of motion, where all compartments can be debrided, the ulnar nerve can be manipulated easily and damage to the medial collateral ligament can be minimized.
