The too-long anterior process and osteochondral lesion of the talus: Is there an anatomical predisposition? A case-control study on 135 feet

IntroductionThe too-long anterior process (TLAP) increases mechanical stress on the hindfoot and could lead to osteochondral lesions of the talus (OLT) by localized hyper-pressure. The purpose of this study is to investigate an association between TLAP and OLT in children.MethodsThis is a retrospective, multicenter, case-control study conducted between 2010 and 2020. The OLT group was compared to a control group (CoG). TLAP is characterized by a distance between the anteromedial process of the calcaneus and the navicular bone (CN) of< 5 mm.ResultsForty-three feets were included in the OLT group and 92 in the CoG. The OLT group had a lower CN distance on CT than the CoG, a median of 2.8 mm versus 3.75 mm (p = 0.002); 86% of patients (37 feet/43) in the OLT group had a CN distance of< 5 mm (OR=3.0 [1.1; 9.5], p = 0.023) compared to 67% in the CoG.DiscussionThe OLT group had an increased risk of developing TLAP compared to the CoG.Level of evidenceIII.     

Osteochondritis dissecans—Does platelet rich plasma really help

Osteochondritis dissecans is a common disorder of knee and can be treated by various methods, depending on age of patient and stability of chondral fragment. In Osteochondritis dissecans ICRS type III lesion i.e. articular cartilage discontinuity but no dislocation, variable rate of union as well as high rate of non-union was observed in previous studies when treated with arthroscopic or open reduction and fixation. In previous study it has been also shown that platelet rich plasma help in fracture healing. In this study we are trying to extend the benefit of platelet rich plasma to Osteochondritis dissecans lesion. We took six patients with OCD, ICRS scale of OCD type III lesion. All Patients were operated Arthroscopiclly. Chondral flap of OCD lesion were fixed with stainless steel cannulated cancellous screw. To enhance union we used platelet rich plasma injections. .We access the union of chondral fragment to parent bone and knee function. Chondral fragment united to parent bone in all patients. To access knee function we used Tagner- Lysholm knee scoring system, in this study preoperatively score was 52.8 where as postoperatively it was 91.8. This study showed PRP is helpful in healing of chondral flap as all the chondral flap of osteochondral lesion united in this study.     

中西医结合治疗距骨剥脱性骨软骨炎的个案报道

目的:报道中西医结合治疗距骨剥脱性骨软骨炎的临床疗效并分析文献。方法:报道山东中医药大学附属医院显微骨科2016年-2018年间3例距骨剥脱性骨软骨炎住院患者,均采用中药内服配合病灶刮除加自体骨膜骨移植术治疗。中药治疗组方以活血化瘀,行气止痛为目的。手术治疗采用硬腰联合麻醉,取内踝纵行切口,于内踝截骨,截骨后下翻内踝,将距骨骨软骨剥脱区充分显露,以小刀切除已剥脱翘起骨软骨,并刨削毛糙区,以剥脱区为受区,内踝截骨2 cm处为供区。分别取骨柱,将供区骨柱打压入受区,并使骨膜与周围软骨位于同一平面,复位内踝,并以两枚空心钉固定。两者配合验证其临床疗效并回顾分析近年相关文献,从解剖、诊断及治疗加以综述。结果:3例患者伤口均为一期愈合,术后6个月症状较术前明显缓解,kofoed评分较前明显改善。从中国知网、万方、维普网检索近50篇文献,分析文献可知,距骨剥脱性骨软骨炎易被误诊漏诊,其主要手术治疗方案有微骨折术、钻孔术、自体软骨细胞移植术、自体骨软骨移植术、同种异体骨软骨移植术等。结论:采用中药内服配合病灶刮除加自体骨膜骨移植术治疗距骨剥脱性骨软骨炎,能缓解患者疼痛,提高功能活动度,值得临床推广。     

Osteochondritis dissecans of the glenoid cavity: a case report

Osteochondrosis dissecans (OCD) is a form of osteochondrosis limited to the articular epiphysis. The most commonly affected areas include, in decreasing order of frequency, the femoral condyles, talar dome and capitellum of the humerus. OCD rarely occurs in the shoulder joint, where it involves either the humeral head or the glenoid. The purpose of this report is to present a case with glenoid cavity osteochondritis dissecans and clinical and radiological outcome after arthroscopic debridement. The patient underwent arthroscopy to remove the loose body and to microfracture the cavity. The patient was followed-up for 4 years and she is pain-free with full range of motion and a stable shoulder joint.     

Bilateral osteochondritis dissecans of the lateral trochlea of the femur: a case report

Osteochondritis dissecans of the bilateral trochlea of femur is unusual case for orthopedic surgeon. The patient was a healthy 15-year-old male with symptomatic osteochondritis dissecans of the bilateral distal lateral femoral condyle of the trochlea. A surgery on the bilateral knee joints was performed simultaneously. The osteochondral free fragment of the right knee was resected by a minimum open surgery after arthroscopic evaluation. In the left knee the fragment was stabilized with multiple cortical bone pegs harvested from the proximal tibia. The surgery was successful, and the patient was able to play basketball 3 months postoperatively. The course of the right knee is currently under careful observation because of the possibility of recurrence. The left knee has remained in an excellent condition for 18 months following surgery with bone pegs.     

Osteomyelitis complicating Sever‘s disease: A report of two cases

Sever's disease is a common cause of heel pain in young children and it has a self-limiting course without long term complications. Osteomyelitis of calcaneus is a sinister condition which can lead to serious complication if treatment is delayed. Indolent nature of calcaneus osteomyelitis leads to overlap in its clinical picture with Sever's disease. Two cases of Sever's disease which were later diagnosed and managed for osteomyelitis are reported. Salient differentiating features of Sever's disease and calcaneus osteomyelitis along with management strategy are discussed.
