Arthroscopic Calcaneonavicular Coalition and Too-long Anterior Process of the Calcaneus Resection in Children.

Persistent symptomatic calcaneonavicular coalition (CNC) and too-long anterior process of the calcaneus (TLAP) are congenital disorders that can benefit from surgical treatment. The arthroscopic technique for CNC and TLAP resection has previously been described. The aim of this prospective study was to describe outcomes following arthroscopic resection of 12 (38.71%) CNC and 19 (61.29%) TLAP cases in 30 consecutive pediatric patients treated between July 2009 and March 2013. There mean age was 12.4 (range 10 to 15) years, and the mean follow-up was 55.2 (range 24 to 79) months. Radiographs, American Orthopaedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Scores, AOFAS pain scores, and patient satisfaction were assessed. All final postoperative imaging scans revealed complete synostosis resection without recurrence. The mean overall AOFAS Ankle-Hindfoot Score increased from 78.87 (95% confidence interval [CI] 76.74 to 81.01) to 93.06 (95% CI 91.10 to 95.03) (p < .001). All patients showed pain reduction after surgery; even 1 patient (3.23%) who initially developed complex regional pain syndrome eventually had a successful outcome. The mean AOFAS pain score increased from 23.87 (95% CI 22.05 to 25.69) to 34.84 (95% CI 32.97 to 36.70) (p < .001). All patients were either satisfied (n = 9 [30%]) or very satisfied (n = 21 [70%]) with the intervention at the final follow-up. Although both arthroscopic CNC and TLAP resection are demanding techniques, they allow for precise coalition resection through a less invasive approach, which may ultimately lead to faster recovery and improved outcomes.

Bone nonunion management in children with a vascularized tibial periosteal graft.

BACKGROUND: Vascularized periosteal graft have demonstrated a tremendous bone healing capacity in children. The objective is to report outcomes on the use of vascularized tibial periosteal graft (VTPG) during bone reconstruction in a series of children with complex bone healing problems. PATIENTS AND METHODS: Cases were collected retrospectively since May 2013 to May 2019, excluding cases of congenital pseudarthrosis of the tibia. Mean age at surgery was 12.8 (range 11-18) years. Indications included treatment of recalcitrant bone nonunion and the prevention of bone allograft-host junction nonunion in seven and three patients, respectively. The periosteal flap, based on the anterior tibial vessels, was harvested as a free flap in six instances and as a pedicled flap in four. RESULTS: Mean follow-up was 25.2 months (range 8-36). The flap showed a 13.6 cm (range 9-16) and mean width 3.4 cm (range 2.7-3.9). Early bone union was achieved, initially through periosteal callus, followed by cortical union at mean times of 2 and 4 months, respectively, in nine cases. The flap was not successful in a patient with severe comorbidities. No donor site complications were registered. CONCLUSIONS: VTPG was fast and high effective for the treatment complex bone nonunion or the prevention of allograft nonunion in children.

Transverse Anterior Approach to the Elbow for Pediatric Displaced Lateral Humeral Condyle Fractures.

BACKGROUND: The anterior approach to the elbow for pediatric lateral condyle fractures (LCF) would provide a better visualization of the articular fracture resulting in better functional results, less complications and a more cosmetically-appealing scar than usually seen with the lateral approach. METHODS: Retrospective study of children undergoing an open reduction and internal fixation of a displaced LCF via an anterior approach with a transverse incision. Bilateral elbow range of motion (ROM), upper limb alignment and complications were registered. A 4-point ordinal Likert-type scale was employed for parents to rate their level of satisfaction with the cosmetic appearance of the scar. RESULTS: Eighteen children of mean age 76 months (range 27 to 101 months) were included. Fractures were classified as Jackob's Type II in 14 cases and Milch's type II in all cases. Mean follow-up was 12 (range 4 to19) months.Successful condral fracture visualization and reduction was achieved in every case. No intra-operative or post-operative complications occurred. In all cases bone union was obtained 4 to 5 weeks after surgery and at final follow-up, active elbow ROM of at least 90%, was obtained. All parents claimed to be "very satisfied" with their child's scar. A lateral spur was identified in 66.7% o patients. CONCLUSION: The anterior approach to the elbow was both a feasible and safe allowing full anatomical cartilage reduction. Complications after this technique might decrease compared to the lateral approach but need future comparative studies. The rate of lateral spur did not decreased. Cosmetic scar results seem to be a clear advantage of this approach compared to the classical lateral approach.

On-Top-Plasty for Atypical Thumb Duplication: A Case Report With 10 Year Follow-up.

BACKGROUND: A very uncommon pattern of thumb duplication consists of an ulnar-side floating thumb and a radial-side distally hypoplastic thumb. METHODS: We report the case of a 15-month-old child with this type of thumb duplication on his right hand treated with an on-top-plasty technique. The ulnar-side segment was pedicled and transferred to the lateral thumb, which was distally resected. RESULTS: A well-aligned and widely mobile thumb with a wide first web and an excellent cosmetic appearance was exhibited 10 years after surgery. CONCLUSIONS: On-top-plasty technique might be amenable to reconstruct certain atypical thumb duplications.

Vascularized ulnar periosteal pedicled flap for forearm reconstruction: Anatomical study and a case report.

PURPOSE: Through an anatomical review, the aim of this study is to define the ulnar periosteal branches of the posterior interosseous vessels (PIV). In addition, we report the clinical utility of a vascularized ulnar periosteal pedicled flap (VUPPF), supplied by the investigated PIV, in a complex case of radial nonunion. METHODS: Ten upper limbs latex colored from fresh human cadavers were used. Branches of the PIV were dissected under 2.5× loupe magnification, noting the periosteal, muscular, and cutaneous branches arising distal to the interosseous recurrent artery. The VUPPF was measured in length (cm) and width (cm). RESULTS: The PIV provided a mean 12.8 periosteal branches to the ulna distributed along the most distal 15 cm, with a mean distance between branches of 1 cm, allowing for the design of a VUPPF which measured a mean 12 cm in length and 1.7 cm in width. We used a VUPPF of 7.8 cm in length and 2 cm in width to treat extensive nonvascularized bone graft nonunion with a defect of 2 cm of the left radius in a 6-year-old girl, secondary to previous Ewing's Sarcoma reconstruction. Successfully consolidation was achieved 6-months after surgery. The patient did not present postoperative complications. At 2-years of follow-up after surgery, active supination was 80° and pronation 0° (due an incomplete interosseous ossification); grip strength was 80% that of the opposite hand. The patient had resumed all her daily activities. CONCLUSIONS: VUPPF may be considered a valuable and reliable surgical option for forearm reconstruction in complex clinical scenarios.

Endoscopic Woodward procedure for Sprengel deformity: case report.

Sprengel deformity (SD) results in a limitation of movement of the shoulder girdle and produces an esthetic defect. Our aim is to assess the feasibility and advantages of a minimally invasive endoscopic approach for SD correction. A 4-year-old boy with a Cavendish grade III right SD. The patient underwent an endoscopic Woodward procedure with access through two small incisions at the level of the upper and lower angles of the scapula. Near-symmetrical shoulder elevation was achieved, with an excellent cosmetic result. The endoscopic Woodward procedure is a feasible, effective, and minimally invasive technique in the treatment of SD. LEVEL OF EVIDENCE: V.

Vascularized fibular grafts extended with vascularized periosteum in children.

PURPOSE: The purpose of this report is to evaluate the results of extending vascularized fibular grafts (VFG) with vascularized periosteum (VPG) in bone defect reconstruction in children. METHODS: Retrospective study of 10 children, mean age at surgery was 9.8 years (range, 4-16 years). Origin of one defect was oncological (n = 5), septical (n = 2), traumatic (n = 2), or congenital (n = 1). In five cases the flap consisted of a VFG and a vascularized epiphyseal transfer (VFET) in five. Mean bone defect was 8.5 cm .Mean length of the vascularized periosteal extension was 5.5 cm (range 3.5-8) for VFET, 4.8 cm for VFG (range 3-8). Bone union was assessed with monthly radiographs. RESULTS: Radiographs showed a periosteal callus at 4 weeks in all cases. Bone union was achieved at a mean of 8.4 weeks (range 4-12). Donor site complications included two cases of flexor hallucis longus contracture, and one case of surgical wound marginal necrosis following FVG. One transient tibialis anterior weakness and one tibialis anterior contracture occurred following VFET harvest. None required surgical treatment. Mean follow-up was 28.7 months (range 7-72). CONCLUSIONS: The association of a vascularized periosteal extension with fibular flaps seems to accelerate flap to recipient bone union. © 2016 Wiley Periodicals, Inc. Microsurgery 37:410-415, 2017.

Osteochondromas around the ankle: Report of a case and literature review.

INTRODUCTION: An osteochondroma or exostosis is a benign bone tumour consisting of a bony outgrowth covered by a cartilage cap that occurs commonly in the metaphysis of long bones, mainly the distal femur, proximal tibia and proximal humerus. PRESENTATION OF CASE: We describe an unusual case of a distal tibia osteochondroma affecting the lateral malleolus of a young girl. DISCUSSION: Most osteochondromas are asymptomatic and seen incidentally during radiographic examination. Osteochondromas are rarely localized in the foot and ankle. CONCLUSION: Although most of the osteochondromas in children should be treated conservatively until skeletal maturity, those affecting the distal tibia or fibula should be treated with surgical excision in order to prevent ankle deformity, syndesmotic lesions or even fracture due to the expanding nature of this benign tumour.
