Comparison of surgical outcomes between bioabsorbable and metal screw fixation for distal tibial physeal fracture in children and adolescent.

PURPOSE: This study aimed to compare the surgical outcomes between bioabsorbable and metal screw fixation for distal tibial physeal fracture in children and adolescents, radiographically and clinically. METHODS: This study included consecutive 67 children and adolescents who underwent open reduction and internal fixation using metal or bioabsorbable screws for the distal tibia physeal fracture. All patients underwent preoperative radiographs, three-dimensional computed tomography scans, and postoperative follow-up teleradiogram. Patients were divided into metal (N = 40) and bioabsorbable groups (N = 27). We compared the surgical outcomes between the two groups in terms of clinical and radiographic outcomes, length of hospital stays, and medical cost. RESULTS: Follow-up duration were significantly longer in the metal group than that in the bioabsorbable group. There was no significant difference in the incidence of growth arrest after surgery and the scores of the Oxford Ankle and Foot Questionnaire between the two groups. However, the total hospital stay was significantly longer in the metal group (5.2 ± 4.8 days) compared to the bioabsorbable group (2.6 ± 0.5 days). Medical costs were significantly higher in the bioabsorbable group than in the metal group with a difference of 397 US dollars. CONCLUSIONS: The use of bioabsorbable screws exhibited therapeutic effects equivalent to that of metal screws for pediatric distal tibia physeal fractures regarding clinical and radiological outcomes. Moreover, it had the advantage of avoiding the need for repeated general anesthesia and secondary operation for implant removal. Therefore, the use of bioabsorbable screws may be a favourable surgical option for treating pediatric fractures.

Physeal injuries of the clavicle: pediatric counterparts to adult acromioclavicular and sternoclavicular joint separations.

The epiphyses at the medial and lateral ends of the clavicle are small, ossify relatively late, and may not fuse until early adulthood. Because of this unique anatomy, pediatric and young adult injuries that involve the clavicle often differ from the patterns typically seen in older adults. Clavicular trauma that affects the acromioclavicular joint laterally or sternoclavicular joint medially often results in a physeal fracture and as such, can go unrecognized or be mistaken for a joint dislocation. Radiographic assessment is challenging, particularly when the epiphysis is not yet ossified. However, MR imaging allows for visualization of the cartilage, periosteum and perichondrium, and ligaments of the affected joints. Lateral clavicle physeal injuries can be categorized by the Dameron and Rockwood system, the pediatric correlate to the Rockwood classification of adult acromioclavicular joint injuries. Medial clavicle physeal fractures, similar to adult sternoclavicular joint dislocations, may result in anterior or posterior displacement. Because of their great ability to heal and remodel, clavicular physeal fractures respond better to conservative management than true acromioclavicular or sternoclavicular joint dislocations. Therefore, it is essential to recognize the true nature of these injuries, as there are implications for successful treatment and appropriate prognosis.

Correction of post traumatic tibial varus deviation with hexapodalic external fixator.

Physeal fractures are typical in childhood and for their involvement of the germinal layer of the physis they can be followed by growth complications. Axial deviation is one of these. Considering the young age of the patients it is critical to restore articular correct alignment with the least invasive surgery possible. We report here the first case of correction of post traumatic tibial varus deviation with exapodalic external fixator.

Posterior tibial slope angle is associated with flexion-type Salter-Harris II and Watson-Jones type IV fractures of the proximal tibia.

PURPOSE: Flexion-type Salter-Harris (SH) II fractures of the proximal tibia, also described as Watson-Jones (WJ) IV fractures, are rare injuries reported among adolescent athletes who are close to skeletal maturity and remain elusive. Due to this classification disagreement, the various treatments range from nonoperative to operative types, and no previous studies have explained the mechanisms of injury or the source of the fracture forces. This retrospective matched case-control study aimed to identify radiological factors that are associated with the fracture forces and to elucidate the mechanisms of these injuries. METHODS: Sixteen flexion-type SH II/WJ IV fractures of the proximal tibia in 12 adolescents (12 males, mean age of 14.6 years) were retrospectively reviewed, and knee alignment on plain radiographs was assessed to compare the radiological outcomes of the operated knees (n = 7), nonoperated knees (n = 9), and uninjured contralateral knees (n = 8). The results were compared to healthy age- and sex-matched control subjects (n = 24 knees). RESULTS: With regard to the radiological outcomes, the posterior tibial slope angle (PTSA) was significantly greater in the nonoperated knees (19.0° ± 1.6°), operated knees (16.8° ± 1.3°), and uninjured knees (13.6° ± 1.3°) than in the healthy knees of the matched control subjects (9.6° ± 0.4°). The anatomical tibiofemoral angle was significantly less in the nonoperated knees (0.7° ± 0.6°) than in the healthy knees of the matched control subjects (3.7° ± 0.4°). CONCLUSIONS: These findings suggest a relationship between an increased PTSA and flexion-type SH II/WJ IV fractures of the proximal tibia, considering the deteriorating effects of an increased PTSA on knee kinematics. Adolescent active athletes with an increased PTSA and partially closed epiphysis of the proximal tibia are at risk for suffering from flexion-type SH II/WJ IV fractures of the proximal tibia until the closure of the proximal tibial epiphysis. LEVEL OF EVIDENCE: Case-control study, Level III.

Mechanism and predisposing factors for proximal tibial epiphysiolysis in adolescents during sports activities.

BACKGROUND: Proximal tibial epiphysiolysis (PTE) can have debilitating consequences for young athletes. The mechanism and predisposing factors for this lesion have yet to be determined. To find a common denominator and a biomechanical explanation for PTE, we were using a retrospective analysis of 15 cases in combination with a systematic review of literature. METHODS: A retrospective review of medical charts was performed to identify all PTE between 2003 and 2012. Records were screened for patient age and gender, sports activity, mechanism of injury, and treatment protocols. Additionally, a literature review (MEDLINE/PubMed database, the Cochrane Library, online search engines) was conducted. RESULTS: Medical charts of 14 adolescents (15 Salter-Harris I and II fractures) were analyzed. The literature review revealed additional 75 fractures. The predominant mechanisms were landing from a jump, takeoff for a jump, stop and go movements, and eccentric muscle contraction with the knee in flexion. The main sports-activities implicated in these injuries were basketball. CONCLUSIONS: Landing from a jump with a decreased knee and hip flexion movement increases tensile forces on the proximal tibia epiphysis. During physiological epiphysiodesis, the growth plate displays an increased vulnerability and such increased tensile forces can lead to a growth plate failure. Neuromuscular fatigue can alter coordination and proprioceptive accuracy during landing from a vertical jump and thus perturbs sagittal shock absorption. In our opinion, trainers should instruct young athletes in techniques that help avoiding uncontrolled high impact landings. LEVEL OF EVIDENCE: Level IV.

Distal tibial triplane fracture with ipsilateral tibial shaft fracture: A case series.

BACKGROUND & PURPOSE: Distal tibial Triplane fracture with ipsilateral tibial shaft fracture is a rare but important problem. This rarely reported combination of injuries if not recognised may lead to deleterious consequences. METHODS/PATIENTS: The local database of all emergency admissions was scrutinised to identify subjects before interrogation of the clinical notes and relevant radiographic imaging. FINDINGS: This paper reports a series of five children who were found to have triplane fracture of the distal tibia with concomitant ipsilateral fracture of the tibial shaft. CONCLUSIONS: We suggest that a high index of suspicion for concomitant fractures should be maintained in the presence of either triplane fracture of the distal tibia or tibial shaft fractures in the peri-adolescent child. Minimum appropriate imaging should include orthogonal full length plain radiographs of the tibia as well as formal ankle radiographs.

A biomechanical comparison of Kirschner-wire fixation on fracture stability in Salter-Harris type I fractures of the proximal humeral physis in a porcine cadaveric model.

BACKGROUND: The physis is the weakest component of immature long bones, and physeal fractures constitute about 30% of fractures in growing dogs. Fractures of the proximal humeral physis typically have a Salter Harris type I or II configuration. These fractures require accurate reduction and adequate stabilization to allow for any potential continued longitudinal bone growth, in conjunction with physeal fracture healing. Conventional internal fixation of these fractures involves insertion of two parallel Kirschner wires, although other methods described include tension band wiring, Rush pinning, and lag screws. However these recommendations are based on anecdotal evidence, and information about the biomechanical stability of physeal fracture repair is sparse. The unique anatomical structure of the epiphyseal-metaphyseal complex makes the gripping of the epiphysis for ex vivo biomechanical testing of physeal fracture repair very challenging. The objective of our study was to biomechanically assess the optimal number (three, two or one) of implanted Kirschner wires in a porcine Salter Harris I proximal humeral physeal fracture model, using motion analysis tracking of peri-fragmental retro-reflective markers while constructs were subjected to a constant axial compression and a sinusoidal torque of +/- 2 Nm at 0.5 Hz for 250 cycles. RESULTS: There were significant differences between the three constructs (three, two or one Kirschner wire repair) for gross angular displacement (p < 0.001). The difference between three pins and two pins on toggle was not significant (p = 0.053), but both three-pin and two-pin fixation significantly reduced rotational toggle compared to one-pin fixation. Construct stiffness was not significantly different between any of the pin groups (p > 0.33). CONCLUSIONS: Motion analysis tracking using peri-fragmental markers in this porcine model of physeal fracture repair found that the stability at the fracture site of one-pin fixation was significantly less than two-pin and three-pin fixation. Whether there was increased stabilization of these fractures with three-pin fixation compared to two-pin fixation was not conclusive in this porcine model.

Surgical outcome of distal tibia Salter Harris II fracture in osteopetrosis patient.

INTRODUCTION: Osteopetrosis is a rare genetic disorder characterized by increased bone density. This condition is clinically manifested with a brittle intramedullary structure and reduced bone toughness, increasing the risk of fracture. A limited case has been reported on the management of physeal fracture in patients with osteopetrosis. The objective of this study is to report a rare osteopetrosis patient who sustains Salter-Harris II at the distal tibia with its long-term follow-up along with its literature review. PRESENTATION OF CASE: We report a case of a four-year-old boy with an established a diagnosis of osteopetrosis brought by the parents to the emergency department after sustaining a fall while playing in the playground. Radiological examination revealed a Salter-Harris type II distal tibial fracture. The patient underwent closed reduction and fixation using the cannulated screw. 18-month postoperative patients have an uneventful healing. DISCUSSION: Osteopetrosis is caused by impaired osteoclast function and differentiation, leading to impaired in remodelling. Salter-Harris type II distal tibial fracture can be treated by either closed reduction or open reduction. A closed reduction was performed successfully with cannulated screw in his patient. CONCLUSION: There is a delayed union of fracture in osteopetrosis patient. This will increase the risk of displacement which will eventually resulted in growth disturbance. Delayed weight bearing and stable fixation is highly recommended.

[Extensor pollicis longus rupture in a pediatric patient: case report and a literature review]. / Rotura del extensor pollicis longus en paciente pediátrico: reporte de caso y revisión de la literatura.

INTRODUCTION: the rupture of the extensor pollicis longus (EPL) tendon is a rare pathology and usually occurs in adult women in relation to distal radius fractures. MATERIAL AND METHODS: we present the case of an adolescent female patient who, after conservative treatment with splinting of a Peterson type I physeal fracture of the radius, suffered an acute extension deficit of the thumb at six weeks, diagnosed with clinical radiological examination as spontaneous rupture of the extensor pollicis longus (EPL). She was treated with extensor pollicis indicis propius (EIP) transfer with satisfactory results and recovering her usual activity one month after surgery. CONCLUSION: this kind of injuries are infrequent in pediatric ages and rarely described in a pediatric patient with immature skeleton, what makes this case something exceptional. It is necessary considering these complications in patients of low ages even with no other risk factors. The most frequent treatment applied in adults as in children is the EIP transference with good results in the long term.

INTRODUCCIÓN: la rotura del tendón extensor pollicis longus (EPL) constituye una patología infrecuente y se presenta normalmente en mujeres adultas en relación con fracturas de radio distal. MATERIAL Y MÉTODOS: se presenta el caso de una paciente adolescente femenino que, tras tratamiento conservador con férula de una fractura fisaria Peterson tipo I en radio, sufre a las seis semanas déficit agudo de extensión del pulgar, diagnosticada mediante examen clínico radiológico de rotura espontánea del extensor pollicis longus. Es tratada por medio de transferencia del extensor propio del índice (EPI) con resultados satisfactorios y recuperación de su actividad habitual al mes postoperatorio. CONCLUSIÓN: este tipo de lesiones son poco frecuentes en edad pediátrica y casi nunca descritas en un paciente pediátrico con inmadurez esquelética, lo cual hace de este caso algo excepcional. Es necesario tener en cuenta este tipo de complicaciones en pacientes de baja edad aún sin otros factores de riesgo asociados. El tratamiento aplicado más frecuentemente, tanto en adultos como en niños, es la transferencia del extensor propio del índice con buenos resultados a largo plazo.

The Surgical Repair of a Salter-Harris Type-2 Physeal Fracture of the Proximal Phalanx in a Foal.

A 6-month-old thoroughbred colt foal was referred to a private equine referral hospital for evaluation of an acute onset, left hind limb lameness. On arrival the foal was 4/5 lame on the left hind at walk and there was diffuse swelling of the left hind pastern and fetlock region. The physical exam was otherwise unremarkable. Digital radiographs of the left hind pastern identified a Salter-Harris type-2 physeal fracture of the proximal phalanx. The fracture was initially treated conservatively using a cast, but the immobilization was not sufficient at achieving adequate reduction. As a result, the fracture was stabilized surgically using a construct consisting of a cortical lag screw, four locking head screws and a locking T-plate. The foal recovered uneventfully and was sound and in race training at a 2 year follow up. This case report highlights that surgical repair via internal fixation is preferable to conservative management of proximal physeal fractures of the first phalanx.

Surgical Management of a Salter-Harris Type I Distal Physeal Fracture of the Tibia in a Calf: A Case Report.

Fractures are common conditions in cattle, including tibial fractures. Physeal tibial fractures are more specific and less frequently met in field conditions. A calf with a Salter-Harris type I distal physeal fracture of the tibia was referred to the National Veterinary School of Toulouse (ENVT), France. Although the use of external fixators in the treatment of tibial fractures is common, distal physeal tibial fractures require a different and specific technique involving them. They were first used as a lever arm to reduce the fracture due to the severe displacement. A hock joint bypass was then performed. Six weeks after treatment, the calf recovered successfully from the use of the affected limb without any adverse sequelae. The present case provides management of a distal tibial fracture using external fixators. This innovative and accessible surgical technique may be used by veterinary practitioners in future similar cases of distal tibial fractures when pins in the distal end cannot be inserted.

Delayed Presentation of Displaced Salter-Harris III Distal Tibia Fracture: Does Transfracture Reduction Yield Satisfactory Outcomes?

LEVELS OF EVIDENCE: Level V.

A Rare Case of Distal Femur Physeal Fracture Dislocation with Positional Vascular Compromise in an Adolescent Male.

Introduction: Physeal fractures are a rare entity to occur around the knee. However, they may prove to be dangerous when encountered due to their proximity to the popliteal artery and associated risk of premature physeal closure. A distal femur displaced, SH type I, physeal fracture is very uncommon and is most likely caused by high velocity trauma. Case Report: Here is a case of right sided distal femur physeal fracture dislocation in a 15-year-old boy having positional vascular compromise (popliteal vessel involvement) as a result of the fracture displacement. He was immediately planned for open reduction and fixation using multiple K wires due to limb threatening condition. We focus on the potential immediate and remote complications, the treatment modality and the functional outcome of the fracture. Conclusion: Due to the potential risk of immediate limb-threatening complication due to vascular compromise, this kind of injury needs emergency fixation. Furthermore, long-term complications like growth disturbances have to be considered and prevented by early definitive treatment.

Traumatic physeal fractures in cats: a review of 36 cases (2010-2020).

OBJECTIVES: The aim of this study was to describe the demography, aetiology, location and classification of physeal fractures in cats, and to describe their management and outcomes. METHODS: Clinical records and radiographs of cats referred for management of physeal fractures were retrospectively reviewed. Fractures of the proximal femoral physis were excluded. Descriptive statistics were used to describe signalment, cause of injury, presence of concurrent injuries, fracture description, treatment modality, complications, follow-up, physeal closure, implant removal and outcome. RESULTS: Thirty-four cats with 36 fractures were included, of which 17 affected the distal femur, 11 the distal tibia and fibula, five the distal radius and ulna, two the proximal tibia and one the distal humerus. Salter-Harris classification was type I in 14, type II in 16, type III in two and type IV in four fractures. Thirty-four fractures were treated with primary fixation, and the most common method was crossed Kirschner wires (24/34 fractures). Complications were observed in 14 fractures, of which 12 were minor. At radiographic follow-up, physeal closure was reported in 23 fractures, of which 15 were considered premature. Implant removal was performed in three fractures. Outcome was good in 28, fair in four and poor in two fractures. CONCLUSIONS AND RELEVANCE: Fracture of the distal femoral physis was the most common physeal fracture seen. Cats presenting with physeal fractures may be skeletally immature or mature with delayed physeal closure. The rate of physeal closure after fracture repair was relatively high but without apparent impact. The frequency of implant removal was very low, indicating that despite having a physeal fracture repair, most cats did not require a second procedure to remove implants. Overall, internal fixation provided a good outcome in most fractures.

Combining Salter-Harris and Dias-Tachdjian could be better at determining the prognosis of distal tibial physeal fractures.

OBJECTIVES: The aim of this study is determining the factors that affect prognosis of distal tibial physeal fractures (DTPF) and analyzing whether Salter-Harris (SH) or Dias-Tachdjian (DT) classification is more predictive for outcomes. METHODS: Patients treated for DTPF were retrospectively analyzed. Fracture patterns were classified according to SH and DT. Treatment methods and fracture characteristics were noted. Distal tibial angles and joint irregularities were analyzed on patient's final ankle radiographs followed by American Orthopedic Foot and Ankle Score questionnaire. RESULTS: 75 patients followed-up between 6 and 96 months meeting the inclusion criteria were evaluated. Joint irregularity was observed in 41.3% and partial premature physeal closure (PPC) in 34.7% of the patients. Lateral distal tibial angle (LDTA) and talocrural angle related deformity were detected in 20% and 14.7% of the patients, respectively. Partial PPC and joint irregularities that have been developed in pronation-eversion-external rotation and supination-inversion injuries (SH type 3, 4) were 62% and 50%, and 42% and 75%, respectively. On follow-ups of supination-external rotation injuries (SH type 2) joint irregularity has never been observed. Following supination-external rotation and supination-plantar flexion injuries, a low rate of partial PPC have been developed; LDTA related deformity was revealed at a high rate of 39.1% after supination-inversion injuries. There weren't any differences observed between the initial displacement, residual displacement or surgical technique and PPC, joint irregularity and angular deformities. Patients treated by ORIF technique had lower AOFAS scores than patients treated by other surgical techniques. CONCLUSIONS: In this study it was revealed that SH classification system is not sufficient alone to determine the prognosis of DTPF, the injury mechanisms causing SH types might be also significant in prediction of the prognosis of DTPF.

Late Ankle Reconstruction in a Child with Remote Traumatic Medial Malleolus Loss: Clinical and Radiographic Outcomes.

Aim: This article aims to describe a novel surgical technique for medial malleolar reconstruction in a young child. Background: Severe open ankle injuries that result in bone and soft tissue loss carry a high risk for complications, especially in children who are still growing. These injuries can cause abnormal growth patterns, degenerative diseases, and recurrent instability. Cases of medial malleolar reconstruction have been previously described but none in a child this young. Case description: We present a case of an 13-year-old girl who suffered an open injury to the medial distal tibia with traumatic loss of the medial malleolus at the age of 2 and later suffered a Salter-Harris II fracture to the ipsilateral distal fibula. She presented with varus alignment, a leg length discrepancy, premature asymmetrical growth arrest, chronic non-union of the distal fibula physeal fracture, and severe attenuation of the deltoid ligament. Her secondary deformities were managed with distal fibula osteotomy and fixation, distal tibial hemi-plafond corrective osteotomy, and medial malleolus reconstruction with iliac crest autograft. Her leg length discrepancy was corrected by epiphysiodesis of the contralateral distal femur and proximal tibia. At the 2-year follow-up, the alignment was well maintained, the graft was healing well, and the patient reported no pain and being able to walk and play sports without a brace. Conclusion: Surgical reconstruction of the medial malleolus with correction for abnormal angulation and leg length discrepancies is critical to promoting healthy growth patterns and quality of life for paediatric patients. This severe open ankle injury can be successfully managed by distal fibula osteotomy and fixation, distal tibial intra-articular osteotomy, and medial malleolus reconstruction with iliac crest autograft. Clinical significance: This novel technique is an effective method for the surgical management of paediatric traumatic medial malleolar bone loss in children who are skeletally immature and are at risk of complications due to further growth.

Growth arrest and its risk factors after physeal fracture of the distal tibia in children and adolescents.

BACKGROUND: . This study performed to investigate the incidence of growth arrest such as leg length discrepancy (LLD) and ankle joint angular deformity and its risk factors after physeal fracture of the distal tibia in children and adolescents. MATERIALS AND METHODS: . Consecutive 78 patients (mean age 11.4 ± 2.0 years; mean follow-up period 2.0 ± 1.2 years) treated for the distal tibia physeal fracture were included. All patients underwent preoperative ankle radiographs, three-dimensional computed tomography (CT) scans, and postoperative follow-up teleradiogram. Patients were divided into two groups according to the LLD and the difference of lateral distal tibial angle (LDTA) with the contralateral limb as follows: Group 1 (growth arrest), patients with LLD ≥ 1cm or difference of LDTA ≥ 5°; Group 2 (normal growth), patients with LLD < 1cm and difference of LDTA < 5°. RESULTS: . The overall incidence of growth arrest was 12.8% (10 of 78). The mean displacement measured using CT scan was 4.4 ± 3.2 mm (range, 0.8-14.9). Of the total 78 fractures, 65 were treated surgically and 13 fractures were treated conservatively. The initial fracture displacement was significantly different between the two groups (p<0.001). However, there were no statistically significant differences between the two groups with respect to other factors. Initial displacement was the only significant risk factor for growth arrest (p<0.003). The cutoff values of initial displacement between the two groups were 5.2mm. CONCLUSIONS: . This study showed that degree of initial displacement was the only significant risk factor for growth arrest after physeal fracture of the distal tibia in children and adolescents. Therefore, physicians should consider the possibility of growth arrest for patients with severely displaced physeal fractures of the distal tibia.

Open reduction and internal fixation for displaced Salter-Harris type II fractures of the distal tibia: a retrospective study of sixty-five cases in children.

BACKGROUND: The treatment for displaced Salter-Harris II (S-H II) distal tibia fractures remains controversial. The purpose of this study was to review S-H II distal tibia fractures and evaluate the rate of premature physeal closure (PPC) treated by open reduction and internal fixation (ORIF). METHODS: We reviewed the charts and radiographs of S-H II fractures of the distal tibia with displacement > 3 mm between 2012 and 2019 treated by ORIF. Patients were followed up for a minimum of 6 months. CT scans of injured side or contralateral ankle radiograph were obtained if there was any evidence of PPC. Any angular deformity or shortening of the involved leg was documented. Multivariable logistic regression was performed to identify risk factors for the occurrence of PPC. RESULTS: A total of 65 patients with a mean age of 11.8 years were included in this study. The mean initial displacement was 8.0 mm. All patients but one were treated within 7 days after injury and the mean interval was 3.7 days. Supination-external rotation injuries occurred in 50 patients, pronation-eversion external rotation in 13, and supination-plantar flexion in two. The residual gap was less than 1 mm in all patients following ORIF and all fractures healed within 4-6 weeks. Superficial skin infection developed in one patient. Ten patients complained of the cosmetic scar. The rate of PPC was 29.2% and two patients with PPC developed a varus deformity of the ankle. Patients with associated fibular fracture had 7 times greater odds of developing PPC. Age, gender, injured side, mechanism of injury, amount of initial displacement, interval from injury to surgery, or energy of injury did not significantly affect the rate of PPC. CONCLUSIONS: ORIF was an effective choice of treatment for S-H II distal tibia fractures with displacement > 3 mm to obtain a satisfactory reduction. PPC is a common complication following ORIF. The presence of concomitant fibula fracture was associated with PPC.

Functional impact of osteosuture in medial bilateral clavicular physeal fracture in teenagers.

INTRODUCTION: Proximal physeal fracture of the medial clavicular physis is a rare specific injury occurring in the immature skeletal. Several studies describe unilateral cases with posterior or anterior displacement and the following complications (vascular and mediastinal compression). An immediate diagnosis and management are necessary to avoid complications. The clinical diagnostic might be obvious or difficult, pain and swelling in the sternoclavicular joint area, sometimes a deformity and focal tenderness. A chest X-Ray may help and a three-dimensional reconstructed computed tomography scan has to be done to evaluate the lesions before surgery. The imaging is useful to confirm and specify the diagnostic and the displacement. PRESENTATION OF CASE: This case report presents 4 cases of proximal physeal fracture of the medial clavicular physis in 2 male-teenagers with bilateral displacement, one posterior and the other asymmetric. DISCUSSION: After reviewing the literature of the unilateral clavicular physeal fracture, we can conclude that the ideal management of these injuries has not been well described. An open reduction associated an osteosuture with non-resorbable suture was performed. One-year follow-up, both of them had full recovery without any functional impact or any complains. This management of the proximal physeal fracture of the medial clavicle on children shows an excellent result according our cases and the literature. CONCLUSION: The purpose of this study is to evaluate the functional impact of osteosuture in medial bilateral clavicular physeal fracture in teenagers after 1-year follow-up.
