RESUMEN
INTRODUCTION: Scapular body fractures represent less than 1% of all skeletal fractures. Operative criteria and risk factors for scapular fracture instability are well defined. Non-operative management of scapular body fractures show satisfactory results but with shortening and medialization of the scapular body. The aim of this study is to evaluate if surgical treatment will result in an improved quality of life and shoulder function compared to non-operative treatment on patients suffering from a scapular body fracture. MATERIALS AND METHODS: From a total of 381 retrospectively identified scapular body fractures, we included 45 patients. The enrolled patients were divided into two groups: the surgical treatment (ST, n = 20) group and the non-operative treatment (NOT, n = 25) group. The Non-Union Scoring System (NUSS) was used to assess bone healing on radiographs. The functional evaluation of the two groups during the follow-up were performed using the Constant Shoulder Score (CSS) and the Quick Disabilities of the Arm, Shoulder and Hand Score (QuickDASH). Complications, reoperation rates, and time until bony union were also documented. The minimum follow-up for this study was designated as 12 months. RESULTS: The ST group had better mean CSS and QuickDASH scores compared to the NOT group at 1, 3 and 6 months of follow-up. No statistically significant difference was detected at 12 months follow-up. ST group also demonstrated improved results in time until bone union, reduction of rehabilitation time, complications and return to work rates. CONCLUSION: This study suggests that surgical treatment for extraarticular scapular fractures can achieve better short-term functional outcomes (3 to 6 months) compared to conservative treatment.

PURPOSE: Non-unions after humeral shaft fractures are seen frequently in clinical practice at about 2-10% after conservative management and 30% after surgical treatment. Non-union, displacement of structures and fixation failure can be hazardous complications. The purpose of our study was to evaluate the outcomes of an on-lay bone graft strut construction with bone chips as grafting augmentation in the management of aseptic non-unions of the humeral shaft. METHODS: From 124 eligible patients with a humeral shaft non-union, we included 48 patients. In all cases an anterolateral humeral approach was used, with an on-lay bone graft using an allograft strut construction and with bone substitute augmentation in the non-union gap. To assess the bone healing on radiographs, we used the non-union scoring system according to Whelan. Patients were followed with objective and subjective scores. RESULTS: In all 48 patients we achieved full bone healing without major complications. The average period of union was 124 days. In 40 cases after healing the alignment was neutral, valgus deformation occurred in 6 cases a varus deformation in 2 cases. At twelve months after surgery, all patients recovered with satisfactory range of motion of shoulder and elbow and a good quality of life, without any radial nerve palsies or other major complications. CONCLUSION: Given the satisfactory results of full bone healing, recovery of the range of motion and the lack of major complications as seen in this study, we find that plating with supporting allograft as a good choice of treatment in the cases of aseptic non-union of the humeral shaft.
RESUMEN
Aim Periprosthetic fracture after knee arthroplasty occurs more frequently in the supracondylar area of femur, especially after low energy trauma associated with torsional or compressive forces. Several techniques have been described for the treatment of displaced fractures. The aim of this study is the evaluation of the outcomes and bone healing of periprosthetic femoral fractures managed by standard plate fixation compared to plating with bone grafting. Methods Thirty-six periprosthetic fractures around the knee were selected. Eighteen patients underwent standard plate and screws fixation while other eighteen were treated by plating associate with a cortical strut. Knee Society Score (KSS) and Short Form 12 (SF12) with the UNION SCORE (RUS) were used for the evaluation of results. Results After a minimum follow-up of 12 months, the results showed a statistically significant difference in SF-12, KSS, and RUS in favour of plating associated to bone graft with respect to the plating alone; four cases of non-union were recorded in the group of patients treated by standard plating. Conclusions Our experience once again demonstrated that plating and bone grafting may ensure a mechanical and biological support for the healing of periprosthetic fracture of the knee more than simple plating.

INTRODUCTION: Non-union after humeral shaft fractures are seen frequently in clinical practice. The incidence is 2-10% after conservative management and up to 30% after surgical treatment. The purpose of this study is to evaluate the outcomes of plate-and-bone-strut-allograft technique with bone chip augmentation for aseptic non-unions of the distal third of the humerus. MATERIALS AND METHODS: 26 consecutive cases were treated using a trans-triceps approach. The non-union was fixed with a 4.5â¯mm Locking Compression Plate combined with a strut bone allograft at the anterior part of the humerus and bone chips. All patients underwent the same rehabilitation protocol of 12 weeks. Clinical evaluation took place 12 months after surgery with the Mayo elbow score and Oxford elbow score. RESULTS: Complete bone healing without complications was achieved in all 26 patients. The average period of radiographic union was 106 days. The average range of flexion-extension was 108° (94°-180°) and pro-supination was 159° (102°-180°). Twelve months after surgery, average Mayo elbow score was 86 (68-100) and the Oxford elbow score was 83 (52-100). CONCLUSION: The plate-and-bone-strut-allograft technique with bone chip augmentation in distal humeral shaft for aseptic non-unions resulted in union of all cases. No adverse events related to the surgery or the materials used were documented.
RESUMEN
Aim To demonstrate validity of a bio-metallic solution in bone healing combined with the quadriceps safe approach in the treatment of nonunions of distal femur while malunions were treated by metallic solution. Methods We treated 57 patients with nonunion or malunion of distal femur at the Orthopaedics and Traumatology Department of a single orthopaedic trauma centre (Italy). A total of 57 patients were divided in two groups: the first (NU) group was composed of 35 patients affected; the second group (MU) was composed of 22 patients affected by malunion of distal femur. Criteria chosen to evaluate the two groups during a clinical and radiological followup were: the quality of life measured by the Short Form (12) Health Survey, the knee function and quality of life related to it measured by the Knee Injury and Osteoarthritis Outcome Score KOOS and the Knee Society Score, bone healing measured by modified Radiographic Union Score by X-rays during the follow-up and CT at one year after the surgery, the difference of the limbs length before and after the revision surgery, and postoperative complications. The evaluation endpoint was set at 12 months. Results There were no statistical differences between the two groups. Conclusion The role of bio-metallic solution in the treatment of nonunions and malunions is to recreate the knee anatomy and functionality compatible with a satisfactory quality of life.
RESUMEN
INTRODUCTION: The SNAC wrist (Scaphoid nonunion advanced collapse) is one of the complications following scaphoid fractures treated conservatively and one of the causes of wrist arthritis that the hand surgeon has to face most frequently. In these cases surgical management is usually warranted. MATERIALS AND METHODS: In the set time frame of 6 years we treated 15 SNAC wrist cases. On average patients underwent surgery five years after the trauma. All patients were treated via dorsal incision with partial carpal arthrodesis and total scaphoidectomy, associated with denervation of the posterior interosseous nerves. A plaster cast was applied to all patients for 3 weeks postoperatively. In the preoperative stage, X-rays of the healthy contralateral limb were taken for the measurement of the normal radiocarpal joint space. Clinical and radiographic follow-ups were conducted at 1,3, 6 and 12 months from the trauma; then every 12 months. Criteria for the evaluation of patients: visual analog pain scale (VAS), average time of radiographic fusion of wrist bones, Active Range of Wrist Motion (WAROM), subjective Mayo Wrist Score (MWS) and The Short Form ( 36) Health Survey (SF-36), return to the main tasks and complications. The evaluation endpoint was set at 60 months. Average time of surgery: 48.3 minutes. Average time of arthrodesis consolidation: 67.8 days. The VAS and WAROM showed a gradual improvement in seriated controls, returning to values almost identical to pre-trauma at a 5-year follow-up. By this time, the MWS and SF-36 scores were similar to pre-trauma. On average, the return to pre-injury daily activities occurred in 12.5 months after surgery. There were no complications. CONCLUSIONS: The partial carpal arthrodesis is a safe and effective procedure for the treatment of SNAC wrist cases. Our results show a progressive and significant improvement in ROM, VAS and great satisfaction from the patient.

INTRODUCTION: Not enough literature is available to evalute the wound complication rate of plates type in distal fibular fractures. AIM: The aim of our study was to compare wound complications of using a third tubular plate compared to LCP distal fibula plate. MATERIAL AND METHODS: This study is a retrospective single-centre study in which was performed plating of fibula in closed ankle fractures. 93 patients were included in our study and assigned in two groups, based on using of different implant : in group A 48 patients were treated with one-third tubular and in group B 45 patients were treated with LCP distal fibula plate. There were no significant differences in the baseline characterisctics. Patients received the same surgical procedure and the same post-operative care, then they were radiologically evalueted at 1-3-12 months and clinical examination was made at 12 months using AOFAS clinical rating system. Categorical data, grouped into distinct categories, were evalueted using Chi-square test. We considered a p value < 0.05 as statistically significant. RESULTS: The wound complications rate of the overall study group was 7.6%. There were no statistical differences in the rate of wound complications between the two groups. There were no differences between both group in percentage of hardware removal at follow-up (overall 5.4%); plate removal was performed earlier in the locking plate because of wound complications. CONCLUSIONS: Our study has shown no difference in radiographic bone union rate, no significant differences in terms of clinical outcomes, in time of bone reduction and wound complication rate between the LCP distal fibula plate and conventional one-third tubular plate. Controversy still exists about the best method for the fracture reduction.

BACKGROUND: Fractures of the proximal part of the humerus represent almost 4-5% of all fractures. The rate of non union is estimated to be 1.1 to 10%. Non union, displacement, and fixation failure can be hazardous complications for these injuries. The purpose of our study was to evaluate the outcomes of plate and bone strut allograft with bone chips grafting augmentation in the management of proximal humeral aseptic non union. METHODS: We treated 16 aseptic non union proximal humeral fractures by the medial humeral shaft bone strut allograft and lateral plate and screws with bone chips grafting. The patients' ages were between 55 and 70 years. The chosen criteria to evaluate the group during the clinical and radiological follow-up were the quality of life measured by The Short Form (12) Health Survey (SF-12), shoulder function and related quality of life measured by the Constant Shoulder Score (CSS) compared with healthy side, bone healing measured by X-rays, and postoperative complications. The follow-up was perfor med with clinical and radiographic controls at 1, 3, 6 and 12 months. Surgical time and international units of red blood cells transfused were also calculated. The evaluation endpoint was set at 12 months. RESULTS: The X-rays bone healing occurred in our group on average of 126.4 days after surgery. The surgical time and blood loss were consistent with standard surgical procedures. The quality of life and functional recovery were excellent after plate and bone strut allograft. CONCLUSIONS: Surgical techniques that increase mechanical stability, while incorporating bone biology, are effective aids for treating problematic fractural patterns.
RESUMEN
HYPOTHESIS/BACKGROUND: Suprascapular nerve injury may be a complication during shoulder arthroscopy. Our aim was to verify the reliability of the existing data, assess the differences between scapulae in the 2 genders and in the same subject, obtain a safe zone useful to avoid iatrogenic nerve lesions, and analyze the existing correlations between the scapular dimensions and the safe zone. METHODS: We examined 500 dried scapulae, measuring 6 distances for each one, referring to the scapular body, glenoid, and the course of the suprascapular nerve, also catalogued according to gender and side. Differences due to gender were assessed comparing mean ± sd of each distance in males and females; paired t test was used to compare distances deriving from each couple. Successively, we calculated our safe zone and Pearson's correlation. RESULTS: We found nonsignificant differences between the right and left distances deriving from each couple; differences due to gender were stated. We defined 3 kinds of safe zones referring to: 500 scapulae; males (139 scapulae) and females (147 scapulae). The correlation indexes calculated between the axis of the scapular body and glenoid, and the posterosuperior distance (referring to the suprascapular nerve) were 0.624, 0.694, 0.675, 0.638; while those with the posterior distance were 0.230, 0.294, 0.232, 0.284. DISCUSSION/CONCLUSIONS: Knowledge of the safe zone, for avoiding suprascapular nerve injury, is important; gender and specific scapular dimensions should be evaluated, as they influence the dimensions of the safe zone. The linear predictors should be used to obtain specific values of the posterosuperior limit in each patient.
