Operative treatment of intraarticular calcaneal fractures: Anatomical and functional outcome of three different operative techniques

INTRODUCTION Management of the intraarticular calcaneal fracture is a challenge. The optimal method of treatment remains controversial. This study evaluates the anatomical and functional postoperative outcomes of displaced intraarticular calcaneal fractures that have been treated using three different techniques of ORIF. PATIENTS AND METHODS Between 2004 and 2011 we treated 143 patients with calcaneal fractures, 40 of these patients (28%) were treated conservatively. This is a retrospective study of the remaining 103 patients (72%) who were operated on consecutively, mainly by one surgeon (NG). Calcaneal fractures were classified according to the Sanders classification. Three types of osteosynthesis were used: standard anatomical plate (SP), locking anatomical plate (LCP) and standard anatomical plate with autologous bone graft (SP+ABG). Clinical outcome was assessed one year after the operation: anatomical reduction was evaluated according to the analysis of Bohlers angle at final follow-up, and functional assessment was conducted using the Maryland Foot Score (MFS). RESULTS The fractures were classified as follows: 35 (34%) Sanders type II, 47 (45.6%) Sanders type III and 21 (20.4%) Sanders type IV. The SP was used in 67 (65%) fractures, LCP in 16 (15.5%) and SP+ABH in 20 (19.4%). The correlation test showed a weak association between the Sanders fracture type and the operation technique (Pearson correlation coefficient r=0.26). The non-parametric tests showed that the fracture type did not significantly influence the postoperative Bohlers angle outcome (p=0.132), or the type of operation (p=0.664). Excellent or good reduction of the posterior calcaneal facet was achieved in all operated fractures. One year after the operation, the distribution of Bohlers angle was normal with a mean 31.9° (SD 4.84) in all three groups. There was no significant difference in the functional postoperative outcome in terms of MFS in the three groups (p=0.601), but the Sanders fracture type had significant influence on the functional postoperative outcome in terms of MFS (p=0.001). CONCLUSION In the representative sample of 103 operatively treated intraarticular calcaneal fractures, anatomical and functional postoperative efficacy outcomes appeared to be similar in all three treatment groups. High-grade displaced intraarticular calcaneal fractures (Sanders IV) had worse functional results irrespective of the type of operation. The optimal method for management of intraarticular calcaneal fracture is operative, using the standard anatomic calcaneal plate. Autologous bone grafting is not required. Large sample comparative studies are still needed.

Small Bowel Injuries in Penetrating Abdominal Trauma during War: Ten-Year Follow-Up Findings

BACKGROUND Injuries of the small intestine are common in penetrating abdominal trauma. This article presents 10-year follow-up results for 23 patients with penetrating small bowel injuries who were treated in Nova Gradiska City Hospital during the 1991-1992 war in Croatia. The early hospital mortality rate was 13% (three deaths), and good results were found for 16 (84%) of 19 patients after 10 years. METHODS The hospital charts of 23 patients who sustained small bowel injuries during an 8-month period were reviewed. Of 20 patients who survived, 19 came for an examination and interview 10 years after injury. The following criteria were used: existence of an abdominal wall defect or hernia, bowel passage problems, and reoperations attributable to the small bowel injury. RESULTS Early results revealed adhesive peritonitis and ileus for three patients demanding early reoperation (13%) and a hospital mortality rate of 13% (three deaths, mainly attributable to multiple injuries). Ten years after injury, 16 patients had no problems, whereas 3 reported occasional abdominal pain. CONCLUSION Penetrating abdominal injuries in war demand urgent diagnostic procedures and, in almost all cases, urgent laparotomy. In cases with no evidence of abdominal penetration and cases involving multiple injuries, an aggressive approach reduces the risk of missing small bowel injuries. Use of established principles for surgical management of small bowel injuries yields good results and low incidences of late complications and difficulties.

Fluoroscopic iliosacral screw placement made safe

AIM Unstable posterior pelvic ring injuries should be stabilised successfully by percutaneous iliosacral screwing. The intervention takes place under intraoperative fluoroscopic guidance. The inlet and outlet views are crucial and are performed by tilting the image intensifier. Safely interpreting fluoroscopic views can be challenging in certain clinical scenarios. We demonstrated on a series of patients howpreoperative CT scans can be used to anticipate the appropriate intraoperative inlet and outlet fluoroscopic views and positioning of the patient on the operating table, thereby avoiding possible operating table obstacles. MATERIALS AND METHODS We analysed at random 30 pelvic CT scans from patients of different ages and both sexes, utilising the sagittal reconstructions. Inlet and outlet angle measurements were calculated on the scans to determine the appropriate intraoperative inlet and outlet views. RESULTS The analysed CT scans showed an average inlet view of 22.3° (range 10.4°-39.8°) and an average outlet view of 42.3° (range 31.5°-53.1°). Sex and age had no influence on results. The calculated required free space under the operating table for unobstructed tilting of the C-arm was a minimum of 145cm. CONCLUSION The significant anatomic variations of the posterior pelvic ring have been well documented in the literature. The angles required to obtain appropriate intraoperative inlet and outlet views are not perpendicular and differ greatly from traditional settings, which directed the beam 45° caudally and 45° cranially. The fluoroscopic beam would need to be angled differently in each patient to obtain ideal cardinal views that ultimately assist in safe iliosacral screw placement. To avoid collision of the C-arm with the operating table, it is essential to provide secure free space under the operating table of at least 145cm.
