Results of treatment of congenital vertical talus by the Dobbs method.

Congenital vertical talus is a rare foot deformity. The hindfoot is valgus and equinus, the midfoot is dorsiflexed and forefoot is abducted due to a fixed dorsal dislocation of the navicular on the head of the talus and the cuboid on the anterior part of the calcaneus. The epidemiology and etiology of vertical talus is unknown. Dobbs et al. (J Bone Joint Surg Am 88(6):1192-200, 2006) described a minimally invasive alternative which allowed to avoid the need for extensive soft tissue release procedures in treatment of congenital vertical talus. Eleven congenital vertical talus feet (group 5 according to Hamanishi) in eight children (four boys and four girls) constituted the study material. Upon the diagnosis, the patients' age ranged from 5 to 26 months old (the mean - 14.6). The treatment involved serial manipulation and casting according to the reverse Ponseti method (from 4 to 7 casts) followed by a minimally invasive approach consisting in temporary stabilization of the talonavicular joint with the use of K-wire and Achilles tenotomy according to the Dobbs technique. Then patients continued the shoe and bar program for 2 years. The X-ray measurements on lateral radiographic included the talocalcaneal angle, tibiotalar angle and talar axis-first metatarsal base angle whereas AP radiographic images-the talocalcaneal angle and talar axis-first metatarsal angle. The Wilcoxon test was used to compare dependent variables. The final clinical assessment made during the last follow-up (the mean: 35.8 months, the range: 25-52) revealed that neutral position of the foot and normal range of motion were observed in ten cases and recurrence of foot deformity in one case. The last X-ray examination showed normalization all of radiological parameters, except for one case, and examined parameters were statistically significant. The minimally invasive technique described by Dobbs should be the first option in treatment of congenital vertical talus. It allows to reduce the talonavicular joint, brings good results and preserves foot mobility. The attention should be put on early diagnosis.

Pediatric Monteggia Fracture Outcome Assessment - Preliminary Report.

BACKGROUND: The term Monteggia fracture refers to a class of injuries encompassing the fracture of the proximal end of the ulna with subluxation or dislocation of the radial head. These injuries account for 0.4-1% of all forearm fractures in children. Despite its low incidence, Monteggia fractures require particular attention, since as much as 30-50% of the cases may be unrecognized, which subsequently leads to complications. The purpose of this paper is to evaluate treatment outcomes of Monteggia fractures in children. Both conservative treatment and surgery were analyzed. MATERIAL AND METHODS: 15 children (7 boys and 8 girls) between the ages of 4-16.3 years (mean age 8.3 years) with Monteggia fractures were hospitalized at our center in the years 2015-2020. Closed reduction and immobilization in a cast were performed in 12 patients, while three children underwent surgical treatment with internal fixation of the ulna. The radial head dislocation was reduced successfully in every patient. RESULTS: Every child from the study group who received conservative treatment regained full elbow mobility as well as normal forearm supination and pronation. Only one of the patients who underwent the surgery demonstrated a 20° deficit in elbow flexion that did not affect limb function. CONCLUSIONS: 1. Our experience shows that closed reduction together with immobilization in a cast is usually a sufficient treatment in Monteggia fractures. 2. However, the dislocated radial head should be properly reduced in all patients. 3. Correct diagnosis and treatment followed by appropriate rehabilitation result in full recovery and no mobility limitations in children and teenagers.

Hip joint pain in children with cerebral palsy and developmental dysplasia of the hip: why are the differences so huge?

BACKGROUNDS: Non-traumatic hip dislocation in children is most often observed in the course of developmental dysplasia of the hip (DDH) and infantile cerebral palsy. The risk of pain sensations from dislocated hip joint differentiates the discussed groups of patients. Will every painless hip joint in children with cerebral palsy painful in the future? METHODS: Material included 34 samples of joint capsule and 34 femoral head ligaments, collected during open hip joint reduction from 19 children with CP, GMFCS level V and from 15 children with DDH and unilateral hip dislocation. All the children were surgically treated.The density of nociceptive fibres was compared between the children with CP and DDH, using S-100 and substance P monoclonal antibodies. RESULTS: More frequent positive immunohistochemical reaction to S-100 protein concerned structures of the femoral head ligaments in children with CP and cartilage losses on the femoral head, when compared to the same structures in children with DDH (p = 0.010). More frequent were found positive immunohistochemical reactions for S-100 protein in the joint capsules of children with cartilage losses (p = 0.031) and pain ailments vs. the children with DDH (p = 0.027). More frequent positive reaction to substance P concerned in femoral head ligaments in CP children and cartilage lesions (p = 0.002) or with pain ailments (p = 0.001) vs. the DDH children. CONCLUSIONS: Surgical treatment of hip joint dislocation should be regarded as a prophylactics of pain sensations, induced by tissue sensitisation, inflammatory process development or articular cartilage defects.

Reliability of clinical evaluation of meniscus repair with the all-inside technique.

INTRODUCTION: The study aimed to compare questionnaire data and clinical evaluation with an assessment of meniscal morphology conducted at arthroscopic anterior cruciate ligament (ACL) reconstruction following meniscal repair. MATERIAL AND METHODS: The study involved a selected group of 17 subjects (5 women and 12 men) aged 14-33 years, who underwent meniscal repair with the Fast-Fix system followed by ACL reconstruction. The mean interval between the procedures was 9 months. Prior to each procedure, the patients were requested to fill in the Lysholm Knee Questionnaire. RESULTS: At review, 14 patients met the criteria of a healed meniscal repair, whereas the remaining 3 subjects presented with signs of meniscal injury. These observations were confirmed at repeat arthroscopy. The Lysholm score for the entire study group increased from a baseline value of 57.3 to 92.2 points postoperatively, with the patients with reruptured menisci also improving, from 58 to 75.3 points. CONCLUSIONS: 1) Our results show that clinical examination is reliable to evaluate the healing of meniscal lesions following all-inside repair, as confirmed by repeat arthroscopy. 2) A far greater increase in the Lysholm score seen in patients whose menisci were confirmed to have healed by repeat arthroscopy indicates that such questionnaires may be of help in the evaluation of treatment outcomes.
