Supracondylar fractures in children: Management and treatment

Supracondylar humeral fractures are widely considered the most common elbow fracture in children. Gartland classification plays a fundamental role in decision-making regarding management and prognosis. Recent literature recommends conservative management for non or minimally displaced fractures, whereas there seems to be a trend towards surgical treatment for all displaced fractures. The preferred treatment for displaced Gartland II and Gartland III fractures is closed reduction and percutaneous fixation with lateral pins. In particular patterns medial pin is recommended for obtain a stable construct. Neurovascular complications are mostly associated with Type III fractures and sometimes surgical exploration with fracture reduction is needed. Correct diagnosis and proper management protocol is mandatory for avoid early and late complications such as neurovascular impairment and malunion

Malunited extra-articular distal radius fractures: corrective osteotomies using volar locking plate

Background: Multiple techniques for corrective osteotomy have been developed in recent years with the same aims: to improve the radiographic parameters and improve motion, pain and grip strength. Volar fixed-angle plates have added a new concept to the treatment of distal radius fractures thanks to the low morbidity of the surgical approach and the strength of the final construct, allowing early mobilization and return to function.Materials and methods: Between 2005 and 2012, 20 patients with symptomatic dorsally malunited extra-articular fractures of the distal radius underwent corrective osteotomy using a volar locking plate without additional bone graft. At a mean follow-up of 50 months, all the patients were clinically and functionally evaluated.Results: All measurements of pain, final range of motion and grip strength significantly improved compared with preoperative measurements. The mean preoperative DASH score reduced from 54 points preoperatively to 25 postoperatively. Based on the modified Mayo wrist score, we obtained 14 excellent and six good results. Palmar tilt improved from an average of 23° to 11°. Radial inclination improved from an average of 29° to 22°, and ulnar variance decreased from an average of 3.6 mm to 0.9 mm. There were two cases of transient median neuroapraxia that resolved before the 6-week follow-up appointment. No other major complications, including non-union and infection, were observed.Conclusion: The volar approach and locking plate, without necessarily the use of bone grafting, proved to be an effective approach for addressing symptomatic and even severe deformities of the distal radius.Type of study/level of evidence: Therapeutic IV

Schwannomas of the upper extremity: analysis of 34 cases

Schwannomas are the most common benign tumours developing in peripheral nerves. They usually present as a slow-growing mass, sometimes associated with pain and paraesthesia. The aim of this study is to define the correct preoperative diagnosis, to review the surgical treatment employed and to evaluate short- and long-term neurological deficits

A new volar plate DiPhos-RM for fixation of distal radius fracture: Preliminary report

We analyzed the efficiency of a new plate DiPhos-RM in CFR-PEEK [carbon-fiber-reinforced poly (etheretherketone)] for the volar fixation of distal radius fractures. The new plate's composition has the advantage of x-ray absolute transparency, therefore allowing to monitor the healing of the fracture. The desired combination of high strength and low rigidity is obtained through the use of the polymer composites CFR-PEEK. In this preliminary study (from March 2012 to June 2012), 10 cases of intra-articular distal radius fractures were treated with DiPhos-RM produced by Lima Corporate (Italy). The fractures were classified according to the AO classification, 4 fractures were type C1, 3 type C2, and 3 were A2. A preoperative computed tomography scan was carried out in all patients. One patient also underwent a postoperative computed tomography scan. Grip strength, range of motion, and DASH score were evaluated at follow-up. There were no cases of hardware failure. Specifically, no loss of position or alignment of fixed-angle locking screws or breakage of the plate were observed. Radiographic union was present at an average of 6 weeks (range, 5 to 8 wk). The overall preliminary experience with this new plate is favorable. The new plate is easy to apply and provides the surgeon dual options of fixed-angle or variable-angle screws. It was rigid enough to maintain the reduction also in AO type C articular fractures. Copyright © 2013 by Lippincott Williams & Wilkins

Treatment of the ulna non-unions using dynamic compression plate fixation, iliac bone grafting and autologous platelet concentrate

Clinical study of a series of ten patients treated between 2004 and 2009 for non-unions of the ulna. The patients have been treated with osteosynthesis using a dynamic compression plate and biological enhancement of the consolidation using bone graft and autologous platelet injection. The follow-up consisted of clinical and radiographic assessment. Functional scores used were the Visual Analogue Scale (VAS) for pain and the Disability Assessment for the Shoulder and Hand (DASH) questionnaire. The mean time of follow-up was 21 months. Considering both clinical and radiological criteria, bony union was achieved in 9/10 cases on average time of 4 months. According to the system of Anderson, 5 patients provided an excellent result, 2 a satisfactory result, 2 an unsatisfactory result and 1 treatment resulted in failure. At follow-up, the mean VAS score for pain in the upper limb was 1 (range, 0-4) at rest and 2 (range, 0-7) during activities. The physical function and symptoms of the upper limb, evaluated with the DASH questionnaire, scored 17 points. In conclusion, at a mean 21 months follow-up, there was high success regarding both forearm alignment, clinical and functional results. The use of three combined methods provides high success regarding both radiological and clinical results, even if we have no information on the prevalent efficacy of one particular method. © Springer-Verlag 2011

Results of replantation of 33 ring avulsion amputations

Purpose: Despite microsurgical advances, it is still difficult to achieve satisfactory functional results in cases of replantations following complete ring avulsion amputations. Our aim is to report the experience we have collected since the early 1990s in the treatment of this type of injury. Methods: We replanted 33 fingers on 33 patients (age, 15-54 y) with complete ring avulsion amputation injuries. Twenty-eight amputations were distal to the insertion of the flexor digitorum superficialis, and 5 were complete degloving injuries with intact tendons. Vascular transpositions and vein grafts were used, and in all cases, only 1 of the digital nerves was repaired. Results: The 29 successful cases were tracked over an average follow-up of 89 months. The average total active motion of the reconstructed finger was 185°. Sensibility evaluated by static 2-point discrimination varied from 9 to 15 mm and by moving 2-point discrimination from 8 to 15 mm. Five patients complained of cold intolerance. Conclusions: Resection of the avulsed digital artery and vein is the most crucial part of the procedure.Vessels reconstruction can be performed using various methods, but vessel transfers from the middle finger appear to be the most reliable solution. The outcome of the cases demonstrates that replantation should be attempted. Type of study/level of evidence: Therapeutic IV. © 2013 American Society for Surgery of the Hand

A new volar plate made of carbon-fiber-reinforced polyetheretherketon for distal radius fracture: analysis of 40 cases

BACKGROUND: Implants based on the polyetheretherketon (PEEK) polymer have been developed in the last decade as an alternative to conventional metallic devices. PEEK devices may provide several advantages over the use of conventional orthopedic materials, including the lack of metal allergies, radiolucency, low artifacts on magnetic resonance imaging scans and the possibility of tailoring mechanical properties. The purpose of this study was to evaluate the clinical results at 12-month follow-up using a new plate made of carbon-fiber-reinforced polyetheretherketon for the treatment of distal radius fractures. MATERIALS AND METHODS: We included 40 consecutive fractures of AO types B and C that remained displaced after an initial attempt at reduction. The fractures were classified according to the AO classification: 21 fractures were type C1, 9 were type C2, 2 were type C3, 2 were type B1 and 6 were type B2. RESULTS: At a 12-month follow-up no cases of hardware breakage or loss of the surgically achieved fracture reduction were documented. All fractures healed, and radiographic union was observed at an average of 6 weeks. The final Disabilities of Arm, Shoulder and Hand score was 6.0 points. The average grip strength, expressed as a percentage of the contralateral limb, was 92 %. Hardware removal was performed only in one case, for the occurrence of extensor tenosynovitis. CONCLUSION: At early follow-up this device showed good clinical results and allowed maintenance of reduction in complex, AO fractures. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV

Management of displaced radial neck fractures in children: Percutaneous pinning vs. elastic stable intramedullary nailing

Background: The treatment of radial neck fractures in children varies according to the displacement, angulation, and skeletal maturity. There is a general agreement that displaced radial neck fractures with more than 30 angulations (Judet type III and IV fractures) should be surgically treated. There are several treatment possibilities for Judet type III and IV fractures including percutaneous pin reduction, elastic stable intramedullary nailing (ESIN), and open reduction with or without internal fixation. In this retrospective study we compared the clinical and radiographical outcomes, and complications following intramedullary versus percutaneous pinning in displaced radial neck fractures in children. Materials and methods: Between 2000 and 2011, 20 patients were treated using closed reduction: in 12 cases we used percutaneous pinning, and in 8 cases we used ESIN. According to Judet classification the two groups were composed as follows: 10 (77 %) type III and 3 (23 %) type IV fractures in the percutaneous pinning group; 4 (57 %) type III, and 3 (43 %) type IV fractures in the ESIN group. Results: After an average of 42 months, excellent results in Mayo elbow performance scores (MEPS) were obtained in 71 and 69 % of ESIN and percutaneous pinning groups respectively, with good results in the remaining cases apart from one fair case (8 %) in the percutaneous pinning group. After a radiological evaluation, all fractures healed in excellent or good alignment. When comparing the two groups, the subjects treated with the ESIN technique had higher range of motion (ROM) in flexion, extension and pronation. No patients developed complications, except three cases of asymptomatic enlargements of the radial head, reported only in the percutaneous pinning group. Conclusion: In this research the clinical outcome, assessed with the MEPS, and the radiological alignment, were comparable between the subjects that were treated with percutaneous pinning and those with ESIN techniques; whereas the ESIN technique demonstrated higher ROM in flexion, extension and pronation. The ESIN technique seems to be the ideal approach both for the higher ROM values and for the absence of complications. © 2012 The Author(s)

Comparison between absorbable pins and mini-screw fixations for the treatment of radial head fractures Mason type II-III

Background: The treatment of comminuted radial head fractures can include prosthetic replacement or open reduction and internal fixation. The purpose of this study is to evaluate the results of two different internal fixation systems for Mason type II-III radial head fractures. Methods: Between 2005 and 2015, 82 patients were treated using pins and 65 patients by mini-screws. The follow-up protocol included: a clinical evaluation 15 days after surgery, and clinical and radiographic evaluations performed at 30 and 60 day intervals, unless any complications were reported by the patient. Over a period of at least 12-months of follow-up, patients were checked and interviewed. Clinical examinations included elbow range of motion (ROM), arm, shoulder and hand Disabilities, (DASH), and the Mayo Elbow Performance Score (MEPS). Results: Sixty-one subjects who had been treated with mini-screws were clinically reviewed at a mean 47.3 \ub1 35.8 month of follow-up; all patients who had been treated using absorbable pins were evaluated at a mean 82.5 \ub1 20.6 month of follow-up. No significant statistically differences were observed between the two groups in the mean ROM, DASH, and MEPS scores. Residual pain was reported in 15.8%of the patients treated by pins and 9.2% patients treated by mini-screws. Secondary displacement of fracture fragments was observed in 8.5% patients treated by pins and 1.6% using mini-screws. Conclusions: Both absorbable pins and mini-screws provided adequate strength and rigidity, allowing good clinical and functional scores at a mid-term follow-up. However, a higher rate of secondary displacement of the fracture fragments was reported among subjects who had been treated using absorbable pins
