RESUMO

BACKGROUND: Both bone forearm fractures (BBFFs) are a common injury amongst the pediatric population. The main indications of surgical fixation are open, irreducible, or unstable fractures. The two most commonly used surgical techniques are closed or open reduction with intramedullary fixation (IMF) and open reduction with plate fixation (PF). The aim of this systematic review and meta-analysis was to determine which fixation method is superior for BBFFs. METHODS: PubMed, Scopus, Web of Science, and CENTRAL were searched to identify studies comparing IMF and PF. We extracted data on union rates, complications, early hardware removal rates, reoperation rates, and radiographic, clinical, and perioperative outcomes. RESULTS: Sixteen studies were included in the analysis, with a total of 922 patients (539 IMF and 383 PF). Similar union rates were achieved by both fixation technique. IMF was associated with a higher incidence of symptomatic hardware, and early hardware removal. Better restoration of the radial bow was observed with the PF group, especially in older children and adolescents. The rate of excellent function was comparable between groups, whereas better cosmesis was reported with the IMF group. Despite shorter fluoroscopy time and immobilization time, PF demonstrated longer tourniquet time, operating time, and hospital stay compared to IMF. CONCLUSIONS: We found no significant difference between IMF and PF in terms of union rates and functional outcomes taking in consideration the merits and demerits of each technique. High-quality randomized controlled trials are, therefore, necessary to determine the superiority of one fixation technique over the other. LEVEL OF EVIDENCE: III.

RESUMO

PURPOSE: Opening-wedge high tibial osteotomy (OWHTO) requires fixation devices for stabilization of the osteotomy gap. The two most commonly used fixation devices are the Puddu and the TomoFix plates. Based on its design, each implant generates a characteristic stability profile. The aim of this randomized controlled trial (RCT) was to investigate the short-term clinical and radiological outcomes of OWHTO using the Puddu and TomoFix plating systems. We hypothesized that the TomoFix plate would achieve superior clinical and radiographic results compared to the Puddu plate. METHODS: A total of 60 patients were randomly allocated to undergo OWHTO either using the Puddu plate or the TomoFix plate if conservative treatment failed with symptomatic medial compartment knee osteoarthritis (OA) stage I or II according to Ahlbäck classification, and varus malalignment. All patients underwent clinical and radiological assessment preoperatively, and at 3, 6, 12, and 24months postoperatively. Radiological measurement of the hip-knee-ankle (HKA) angle, and posterior tibial slope (PTS) was performed. Functional assessment was carried out using the Hospital for Special Surgery Knee-Rating Scale (HSS) and the Western Ontario McMaster Universities (WOMAC) Osteoarthritis Index. Patients were also evaluated for intraoperative and postoperative complications throughout the follow-up period. RESULTS: The mean angular correction was 9.6±4°, and 10.5±4.8° in the Puddu and TomoFix groups, respectively (p=0.488). The mean PTS change was significantly higher in the Puddu group (3.4±1.1°) compared to the TomoFix group (0.8±0.7°) (p<0.001). There was a statistically significant improvement in the mean HSS and WOMAC in both groups until one year postoperatively. Neither HSS nor WOMAC showed a statistically significant difference between the Puddu and TomoFix groups at any time during the first two postoperative years. The overall complication rate was not significantly different between the Puddu and TomoFix groups. However, the TomoFix group demonstrated higher incidence of symptomatic hardware (23% vs. 3.3%) and removal of metalwork (17% vs. 0%) than the Puddu group (p=0.023 and 0.020, respectively). CONCLUSION: This RCT suggests that the implant choice for OWHTO has no significant impact on functional outcomes during the first 2years postoperatively. While the Puddu plate was associated with an unintentional increase in the PTS during the surgery, both implants allowed coronal and sagittal plane corrections to be preserved postoperatively. The overall complication rates were similar, but the TomoFix required more material to be removed because it is more cumbersome. However, these results need to be confirmed on a larger scale. LEVEL OF EVIDENCE: II; randomized controlled trial.

RESUMO

PURPOSE: This systematic review aimed to compare survivorship and plate-related results of Puddu and TomoFix plates in opening-wedge high tibial osteotomy (OWHTO). METHODS: PubMed, Scopus, EMBASE, and CENTRAL databases were searched from January 2000 until September 2021 for clinical studies involving patients with medial compartment knee disease and varus deformity undergoing OWHTO using the Puddu or TomoFix plating systems. We extracted survival data, plate-related complications, and functional and radiological outcomes. The risk of bias assessment had been carried out using Cochrane Collaboration's quality assessment tool for randomised controlled trials (RCTs) and Methodological Index for Non-Randomised Studies (MINORS). RESULTS: Twenty-eight studies were included. The total number of knees was 2568 in 2372 patients. The Puddu plate was used in 677 knees, while the TomoFix plate was used in 1891. The follow-up ranged from 5.8 to 147.6 months. Both plating systems were able to delay conversion to arthroplasty at different follow-up intervals. However, osteotomies fixed by the TomoFix plate achieved higher survival rates, especially at mid-term and long-term follow-ups. In addition, fewer complications were reported with the TomoFix plating system. Although both implants achieved satisfactory functional outcomes, high scores could not be maintained throughout long-term intervals. Regarding radiological results, TomoFix plate was able to achieve and maintain larger degrees of varus deformity, while preserving the posterior tibial slope. CONCLUSIONS: This systematic review demonstrated the superiority of the TomoFix over the Puddu system as a safer and more effective fixation device in OWHTO. Nevertheless, these results should be interpreted with caution due to the lack of comparative evidence through high-quality RCTs.

RESUMO

INTRODUCTION: The objective of this study is to evaluate the outcomes of arthroscopic rotator interval release for the treatment of frozen shoulder and compare the results in patients with and without diabetes. METHODS: thirty-two patients with frozen shoulders were divided into two groups; 19 diabetics and 13 non-diabetics. All patients underwent arthroscopic rotator interval release. The VAS and UCLA score were assessed pre-operatively and post-operatively; after 1, 3, and 12 months and compared between groups. RESULTS: The VAS and UCLA score was significantly improved in both groups during follow-up intervals (p < 0.01). There was no significant difference between diabetic and non-diabetic patients in VAS and UCLA scores during follow-up times (p-values > 0.05). CONCLUSION: Arthroscopic rotator interval release provides significant improvement of frozen shoulder with no difference in results between diabetic and non-diabetic patients. LEVEL OF EVIDENCE: Level 2; Prospective Comparative study.

RESUMO

INTRODUCTION: Distal radius fractures are the most frequent upper limb injuries encountered by orthopedic surgeons. Surgical treatment of distal radius fractures is preserved for unstable and displaced fractures. A randomized controlled trial was conducted to compare the radiological and functional outcomes of bridge plating (BP) to external fixation (EF) in comminuted intra-articular distal radius fractures. METHODS: Sixty patients with distal radius fractures were eligible for treatment by means of ligamentotaxis using either a dorsal bridge plate (30 patients) or an external fixator (30 patients) with or without supplementary Kirschner wires (K-wires). Radiological evaluation was done using the radial inclination angle, radial length, and the volar tilt. Clinical evaluation was performed using ranges of wrist motion, grip strength, Visual Analogue Scale (VAS), and a validated Arabic version of the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire RESULTS: Patients were followed up for 12 months. No significant difference was found in terms of radiographic parameters or ranges of wrist motion. At 3-months follow-up, bridge plating group had stronger grip strength, lower Disability of the Arm, Shoulder, and Hand scores, and lower Visual Analogue Scale. However, both groups had similar functional outcomes at last follow-up. External fixation group had a higher rate of postoperative complications. CONCLUSION: In comparison to external fixation, bridge plating may provide earlier functional recovery with lower complication rates. However, no functional or radiological superiority were demonstrated at 12-months follow-up.

RESUMO

PURPOSE: Idiopathic congenital talipes equinovarus is the most commonly encountered congenital deformity of the foot. Ponseti technique of manipulation is the treatment of choice. The Pirani classification is a reliable scoring system for clinical evaluation of clubfeet. The role of radiographic parameters in the evaluation and treatment of clubfeet is still controversial. The aim of this study was to evaluate the correlation of radiological parameters with clinical correction in patients with idiopathic clubfeet undergoing correction using Ponseti method. METHODS: Between March 2018 and March 2019, 42 feet in 27 patients with idiopathic clubfeet were treated in our hospital. We used the Pirani scoring system for clinical evaluation. Anteroposterior and lateral views of the feet were taken before and after correction and at the last follow-up. The anteroposterior view was evaluated for the talocalcaneal angle and talo-first metatarsal angle, while the lateral view was only evaluated for the talocalcaneal angle. RESULTS: Twelve were boys (44.4%), and 15 were girls (55.6%). The deformity was bilateral in 15 patients (55.6%) and unilateral in 12 patients (44.4%). The average age was three months. According to the Pirani score, the mean Pirani Total score was 4.4 before correction and reduced to 0.4 after correction. The mean talocalcaneal angle in anteroposterior and lateral views was 15.1° and 7.8° before correction, increased to 32.7° and 31.8° after correction, respectively. The mean talocalcaneal index increased from 23.2 before correction to 64.5 after correction. The mean talo-first metatarsal angle in anteroposterior view improved from 25.7° before correction to - 1.6° after correction. The relation between the differences in Pirani scores before and after correction and the differences in measured radiographic parameters before and after correction revealed a statistically significant correlation. CONCLUSION: Radiographic parameters showed a statistically significant correlation with the clinical outcome. Thus, evaluation of clubfeet correction treated by Ponseti technique can rely mainly on clinical scores with limited utilization of radiological assessment.

RESUMO

We prospectively compared outcomes of two surgical procedures for Stage II and IIIa Kienböck's disease with negative ulnar variance. Group I (13 wrists) was treated with radial shortening alone, and Group II (14 wrists) with combined radial shortening, bone grafting and implantation of a vascular pedicle. At follow-up 3 to 7 years (mean 4.5) after operation, scores by the Quick version of the Disability of Arm, Shoulder and Hand questionnaire and scores for pain and grip strength were significantly better in Group II, but the differences were rather small. On MRI all patients in Group II had revascularization, but 11 patients in Group I had not. We conclude that combining radial shortening with the revascularization procedure improved revascularization. Clinically, both treatments were efficient, and the additional bone grafting and vascular pedicle insertion did not greatly improve function, although statistically there were differences in several follow-up variables. This study also could not identify the independent role of the three procedures (drilling, grafting and artery insertion) in Group II, because decompression or bone grafting alone may be effective.Level of evidence: II.

RESUMO

BACKGROUND: Traumatic defects of multiple metacarpal bones can be addressed using conventional or vascularized bone grafts. When associated with extensive skin and tendon loss, the treatment becomes more challenging. The aim of the study was to describe the results of using free osteocutaneous fibular flap placed in a new fashion for the reconstruction of complex hand defects. PATIENTS AND METHODS: Six patients with complex hand defects underwent reconstruction using free osteocutaneous fibular flap placed in trapezoidal fashion with two-stage tendon reconstruction using fascia lata graft. The mean age at the time of injury was 34.7 years (range: 14-54 years). The injury was caused by motor vehicle accident in four patients, machine injury in one patient, and falling from height in one patient. All patients had extensive three or four metacarpal bones defects, segmental loss of tendons, and large skin defect ranging from 6 × 10 cm to 10 × 15 cm. The fibular graft was divided into three segments and positioned in a trapezoidal fashion with the middle bone segment placed transversely to support the bases of the proximal phalanges while the first and third bone segments were placed obliquely along the metacarpal axis converging toward the remaining metacarpal bases and/or carpal bones. At final follow-up visit, the finger range of motion was assessed using the total active motion (TAM) scoring system. Functional outcome was evaluated by the disabilities of the arm, shoulder and hand (DASH) score. Active range of motion (AROM) of the pseudo-metacarpophalangeal (MP) joint was measured. The handgrip strength was measured using Jamar hydraulic dynamometer. RESULTS: The mean length of the harvested fibular graft was 18 cm (range: 17-19). The mean size of the skin paddle was 7.5 × 13.1 cm (range: 6 × 10 cm to 10 × 15 cm). Fibular flaps survived in all patients. The mean follow-up period was 30.8 months (range: 24-40 months). The mean time to achieve bone healing was 3.8 months (range: 3-5 months). The mean TAM was 185° (range: 165-204°) and TAM percentage was described as excellent in two patients and good in four patients. The mean AROM at the pseudo-MP joint was 53.8° (range: 42-70°). The mean injured handgrip strength was 27.3 kg (range: 23-31 kg) and the mean grip strength ratio was 74.8% (range: 69-80%). The mean DASH score was 19.6 (range: 11.67-26.67). Pin tract infection, partial skin paddle necrosis, and wound infection were reported. CONCLUSION: The fibular osteocutaneous flap arranged in trapezoidal fashion is a viable choice for the reconstruction of complex hand defects, particularly when the metacarpophalangeal joints are not preserved.

RESUMO

Study Design Prospective study. Objective The aim of this study was to evaluate the clinical and radiologic results of using free vascularized fibular graft (FVFG) for anterior reconstruction of the cervical spine following with varying levels of corpectomy. Methods Ten patients underwent anterior cervical reconstruction using an FVFG after cervical corpectomy augmented with internal instrumentation. All patients were evaluated neurologically according to the Japanese Orthopaedic Association (JOA) and modified JOA scoring systems and the Nurick grading system. The neurologic recovery rate was determined, and the clinical outcome was assessed based on three factors: neck pain, dependence on pain medication, and ability to return to work. The fusion status and maintenance of lordotic correction by the strut graft were determined by measuring the lordosis angle and fused segment height (FSH). Results All patients achieved successful fusion. The mean follow-up period was 35.2 months (range, 28 to 44 months). Graft union occurred at a mean of 3.5 months. The mean loss of lordotic correction was 0.95 degrees, and the mean change in FSH was <1 mm. The neurologic recovery rate was excellent in four patients, good in five, and fair in one. All patients achieved satisfactory clinical outcome. No neurologic injuries occurred during the operations. Conclusion The use of FVFG is a valuable and effective technique in anterior cervical reconstruction for complex disorders.

RESUMO

PURPOSE: A retrospective study to compare the radiologic and clinical outcomes of 2 different anterior approaches, multilevel anterior cervical discectomy with fusion (ACDF) using autologus ticortical bone graft versus anterior cervical corpectomy with fusion (ACCF) using free vascularized fibular graft (FVFG) for the management of cervical spondylotic myelopathy(CSM). METHODS: A total of 15 patients who underwent ACDF or ACCF using FVFG for multilevel CSM were divided into two groups. Group A (n = 7) underwent ACDF and group B (n = 8) ACCF. Clinical outcomes using Japanese Orthopaedic Association (JOA) score, perioperative parameters including operation time and hospital stay, radiological parameters including fusion rate and cervical lordosis, and complications were compared. RESULTS: Both group A and group B demonstrated significant increases in JOA scores. Patients who underwent ACDF experienced significantly shorter operation times and hospital stay. Both groups showed significant increases in postoperative cervical lordosis and achieved the same fusion rate (100 %). No major complications were encountered in both groups. CONCLUSION: Both ACDF and ACCF using FVFG provide satisfactory clinical outcomes and fusion rates for multilevel CSM. However, multilevel ACDF is associated with better radiologic parameters, shorter hospital stay and shorter operative times.

RESUMO

BACKGROUND: U-shaped sacral fractures or Jumper's fractures are rare injuries in adults and are even rarer in the pediatric population. These fractures share a common pathoanatomy where the pelvis as a unit together with the bilateral alar parts and the lower part of the sacrum, loses its skeletal and soft tissue connections to the remaining axial skeleton and hence the term spinopelvic dissociation. This report describes an unusual pattern of spinopelvic dissociation in a young child where the transverse process of the fifth lumbar vertebra was avulsed on one side (spinal side avulsion), whereas on the other side, complete iliac crest apophyseal avulsion took place (pelvic sided avulsion). To our knowledge, this combination of injuries was not reported before. The available literature describing pediatric U-shaped sacral fractures were also reviewed to help explain the pathoanatomic basis of this association. METHODS: An 8-year-old boy sustained a U-shaped sacral fracture with avulsion of the left iliac crest apophysis. A search in the English literature was performed for all reports of U-shaped sacral fractures in pediatric patients (≤ 18 y of age), as well as the relevant literature, which describes the pathoanatomy, possible radiologic findings, and current classification systems and treatment options. RESULTS: Fixation using a 7.3 mm percutaneous iliosacral screw was performed. At the latest follow-up, the child had no pain, was fully bearing weight on lower extremities, and was neurologically intact. The literature review yielded 6 other pediatric patients with U-shaped sacral fractures in 4 articles. CONCLUSIONS: In young children with immature pelvis, the iliac apophysis may be avulsed instead of the transverse process of the fifth lumbar vertebra by forces transmitted through the iliolumbar ligament. The apophysis will therefore keep its attachment to the abdominal and trunk muscles, whereas the bony iliac wing and the pelvis would be dissociated from the axial skeleton. Otherwise, the pathoanatomy of these injuries is the same as described in adults. LEVEL OF EVIDENCE: Level IV.

RESUMO

PURPOSE: We reviewed 18 patients who had received double free muscle transfers and wrist arthrodesis to determine the effect of the stiff wrist on digital motion and function. METHODS: The patients were 15 men and 3 women with a mean age of 24 years. We determined the total active motion of the metacarpophalangeal and interphalangeal joints just before performing the arthrodesis and at final follow-up. We recorded the Disabilities of the Arm, Shoulder, and Hand functional score at the same times. RESULTS: All of our patients showed evidence of fusion at a mean of 12 ± 2 weeks (range, 10-15 wk). The digital mean total active motion was 39° ± 21° before arthrodesis and 49° ± 25° after arthrodesis. Preoperative Disabilities of the Arm, Shoulder, and Hand scores significantly decreased after fusion. Three cases were complicated postoperatively by wound hematoma. Five patients required wrist arthrodesis hardware removal because of skin irritation. CONCLUSIONS: Wrist fusion in patients receiving double free muscle transfers resulted in improved finger range of motion and overall hand function. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

RESUMO

BACKGROUND: The tendinous portion of the transferred muscle following double free gracilis muscle transfer for reconstruction of prehensile function in complete paralysis of the brachial plexus has a tendency to adhere to the surrounding bed and thus impede active finger motion despite powerful contraction of the muscle per se. The purpose of this study was to evaluate the effectiveness of early postoperative passive mobilization of the tendon to prevent its adhesion and the need for tenolysis. METHODS: Of 34 patients who underwent double free gracilis muscle transfer technique, the initial 19 patients (group 1) underwent the conventional postoperative management consisting of 6 weeks of immobilization, and the following 15 patients (group 2) had early passive mobilization. Postoperative active range of motion of elbow and finger joints and the incidence of tenolysis were reviewed. RESULTS: Early passive mobilization technique in group 2 negated the need for tenolysis of the transferred muscle, whereas 10 of 38 transferred muscles in group 1 required tenolysis to improve finger motion. Before tenolysis, there was a significant difference of total active finger motion between group 1 and group 2, although there was no significant difference in the total active finger motion between group 1 and group 2 after tenolysis. CONCLUSION: Early passive mobilization in the postoperative period, consisting of tendon compression at the elbow and assisted resistance exercises of finger and wrist joints, can prevent postoperative adhesion and improve tendon excursion and motion of the free transferred muscle.

RESUMO

There are several options for the treatment of traumatic tibial defects. Among these options, free vascularized fibula and Ilizarov bone transport are well-known and effective techniques. The differences between both techniques and the indications for each of them are not well studied in the literature. Between September 1995 and December 2004, Ilizarov bone transport and free vascularized fibula were used to treat 25 traumatic bone. Patients were divided into two groups, Ilizarov group (12) and free fibula group (13). Preoperative data, operative data, duration of treatment, functional outcome, range of motion loss, number of secondary procedures, and type and rate of complications were compared in both groups. All the cases were ultimately united in both groups. Operative time and blood loss were significantly higher in the free fibula group. Although external fixation time was longer in the Ilizarov group, the overall duration of treatment was similar. Range of motion loss was less in the Ilizarov group, but the overall functional outcome was similar. There was no difference in complication rate, or number secondary procedures. Defect size was found to have the most significant effect on the results. Results were much better in the free fibula group when the defect length was 12 cm or more while the results were better in Ilizarov group when the defect length was less than 12 cm. We recommend using free vascularized fibula for traumatic tibial defects of 12 cm or more, whenever experience is available.

RESUMO

In Erb (C5-C6) type of palsy due to traumatic brachial plexus injury, function is dependent upon the ability of the arm to maneuver and stabilize the hand for action. Complete loss of power of elbow flexion after brachial plexus injuries is a severe disability. If there is control of the shoulder, elbow flexion is of major importance. Various types of procedures have been described to recover or reanimate elbow flexion for chronic or failed upper type paralysis, including free muscle transfer, unipolar and bipolar pedicled muscle transfer, and various tendon transfers. In this article, we describe the surgical technique of bipolar pectoralis major transfer and our experience with this type of transfer, wherein we prefer to transfer all components of the pectoralis major muscle including the sternocostal and clavicular origins and humeral insertion without a fascial graft by the inclusion of a strip of the rectus abdominis fascia along with the flap.

RESUMO

We reviewed 36 traumatic brachial plexus injury patients with C5 nerve root injury. We used the choline acetyltransferase (CAT) activity measurement as a gold standard indicator of repairability to assess the reliability of the conventional techniques (preoperative clinical, electrophysiologic, and radiologic examination and intraoperative clinical and electrophysiologic examinations). We proposed a repairability scoring system composed of the correlated conventional techniques and tested the validity of this scoring system using the same reference technique (CAT activity measurement). We found no significant correlation between sensation at C5 dermatome and electromyography study with C5 repairability. On the other hand, we found a significant correlation of Tinel sign, myelography, macroscopic and microscopic examination, and electrical stimulation with C5 repairability. Based on these results, we propose a simple 21-point scoring system to evaluate the repairability of C5 nerve root that is composed of Tinel sign, myelography, macroscopic and microscopic appearance, and electrical stimulation. The scoring system was found to be highly significantly correlated with C5 repairability. We concluded that our proposed evaluation scoring system is a reliable method for C5 repairability evaluation, and it can replace sophisticated techniques.

RESUMO

Comminuted fractures involving the articular surface of the base of the proximal phalanx are relatively rare and pose a challenging problem for hand surgeons because of the difficulty in achieving an accurate reduction and secure fixation of the articular surface. These fractures usually comprise a volar base fracture associated with a central depression of the articular surface. We describe a technique for open reduction and plate fixation of intra-articular fractures of the base of the proximal phalanx through a volar A1 pulley approach. Compared with the dorsal approach, this technique offers the advantages of direct visualization of the volar base fragment and the depressed central fragment, allowing for a more accurate reduction and rigid internal fixation using a volar buttress plate. In addition, there is no interference with extensor apparatus. Although our experience is limited to 4 patients, we have had a positive experience with this technique. The technique is useful for internal fixation of intra-articular fractures of the base of the proximal phalanx.

RESUMO

Brachial plexus palsy caused by traction injury, especially spinal nerve-root avulsion, represents a severe handicap for the patient. Despite recent progress in diagnosis and microsurgical repair, the prognosis in such cases remains unfavorable. Neurotization is the only possibility for repair in cases of spinal nerve-root avulsion. Intercostal neurotization is a well-established technique in the treatment of some severe brachial plexus lesions in adults. In this article, we describe our experience and technique of intercostal nerve harvest for transfer in various neurotization strategies in posttraumatic brachial plexus reconstruction. Intercostal nerve harvest is a technique requiring meticulous technique and careful dissection along with proper hemostasis. It is also very important to preserve the serratus anterior muscle insertion and keep soft tissue stripping to a minimal. We do not osteotomize the ribs and believe that this adds to the morbidity and length of the procedure. Neurotization using intercostal nerves is a very viable procedure in avulsion injuries of the brachial plexus; however, there is some concern that in the presence of ipsilateral phrenic nerve palsy, it may lead to a significant compromise of respiratory function. In our experience, this is negligible with good long-term results.
