The Treatment of Subtrochanteric Fracture with Reversed Contralateral Distal Femoral Locking Compression Plate (DF-LCP) Using a Progressive and Intermittent Drilling Procedure in Three Osteopetrosis Patients.

OBJECTIVE: To describe the application of reversed contralateral distal femoral locking compression plate (DF-LCP) inserted through a progressive and intermittent drilling procedure in the treatment of osteopetrotic subtrochanteric fracture (OSF). METHODS: Three patients (one male and two females with an average age of 45.33 ± 11.09 years) with OSF hospitalized between September 2015 and September 2020, were included in this present study. Lateral approach was applied in all patients who accepted open reduction and internal fixation (ORIF) with a reversed contralateral DF-LCP inserted through a progressive and intermittent drilling procedure. The operation time and intraoperative blood loss were recorded to evaluate the efficiency of this surgical method. Physical examination and imaging examination of the fracture site were used to evaluate the fracture union status, the position and stability of the implant, and the alignment of the injured limb at 1, 3, 6, and 12 months after operation, then a subsequent visit was conducted at least once a year. Harris Hip Score (HHS) was used to evaluate the hip joint function at 6 and 12 months after operation. RESULTS: The average operation time was 140 ± 21.60 min (110, 160, and 150 min); The average intraoperative blood loss was about 333.33 ± 23.57 ml (300, 350, and 350 ml). The average follow-up time was 22.33 ± 7.41 months (29, 26, and 12 months). All patients achieved bone union with an average time of 6.67 ± 0.94 months (6, 8, and 6 months). At the time of 6 months after operation, case 1 and 3 were almost pain-free and could walk with full weight bearing while case 2 could walk only with partial weight bearing using a crutch. The HHS scores of cases 1, 2, and 3 were 84/100, 74/100, and 92/100, respectively. At the follow-up at 12 months after operation, the HHS score improved to 91/100, 81/100, and 96/100, respectively. The contralateral incomplete old subtrochanteric fracture was deteriorated in case 1 at 26 months after operation. After 3 months of limited weight bearing using a crutch, bone union was verified in radiograph imaging. Fresh contralateral subtrochanteric fracture occurred in case 2 at 26 months after operation, which was treated using a similar surgical approach, and its clinical outcome is under follow-up. Moreover, no perioperative complications including operation-related death, vascular/nerve injury, deep venous thrombosis, pulmonary embolism, and incision infection, and long-term complications involving malunion, nonunion, implant failure, ankylosis, heterotopic ossification, osteonecrosis, and osteomyelitis were identified. CONCLUSION: The application of reversed contralateral DF-LCP in OSF is practicable and reliable. Progressive and intermittent drilling is a safe and efficient method for implant insertion in this complicated situation.

Treatment of Chronic Anterior Shoulder Dislocation by Coracoid Osteotomy with or without Bristow-Latarjet Procedure.

OBJECTIVE: To investigate the clinical efficacy and outcomes of the coracoid osteotomy with or without Bristow-Latarjet procedures in the treatment of chronic anterior shoulder dislocation (CASD). METHODS: Between January 2013 and January 2019, 20 shoulders of 18 patients who were diagnosed with chronic anterior dislocation and underwent open reduction in our trauma center were retrospectively studied. Open coracoid osteotomy with Bristow-Latarjet procedures were performed on 16 shoulders and open coracoid osteotomy without Bristow-Latarjet procedures were performed on four shoulders. Open coracoid osteotomy with or without Bristow-Latarjet procedures were chosen on the basis of the stability of the shoulder after reduction. Outcomes were assessed preoperatively and postoperatively with the visual analog scale (VAS) for pain, the American Shoulder and Elbow Surgeons (ASES) score, the University of California Los Angeles (UCLA) shoulder rating scale, and the range of motion (ROM) for shoulder activity. RESULTS: There were three males and 15 females with an average age of 60.94 ± 2.69 years. The time between dislocation and treatment ranged from 21 to 240 days with an average of 73.3 ± 14.4 days. All patients were available for a mean follow-up of 15.2 ± 4.3 months. No procedure-related death or incision-related superficial or deep tissue infection was identified in all cases. No iatrogenic neurovascular injuries or fractures were found in this study. At the time of 12 months follow-up, the range of motion and the shoulder functional evaluation (VAS [P < 0.001], ASES [P < 0.001], and UCLA score [P < 0.001]) in patients who underwent Bristow-Latarjet procedures were significantly improved. Subluxation after surgical procedure was found and confirmed in one patient and this patient refused to undergo revision surgery. According to the Samilson and Prieto classification system, 16 shoulders were assessed as grade 0, three shoulders were grade 1, one shoulder was grade 2. CONCLUSIONS: Coracoid osteotomy with or without Bristow-Latarjet procedure yielded an acceptable clinical result in this study. This method has the advantages of enlarging the exposure of surgical field, assisting reduction of shoulder, and convenient conversion to Bristow-Latarjet procedure. It is an efficient and reliable method for treatment of chronic anterior shoulder dislocation. A 69-year-old woman diagnosed with right chronic anterior shoulder dislocation with large Hill-Sachs lesion. The latarjet procedure with remplissage technique was applied for this patient.

Lumbopelvic fixation for multiplanar sacral fractures with spinopelvic instability.

Sacral fractures with both transverse and bilateral vertical fracture components are by definition multiplanar fractures, and often present with spinopelvic instability and cauda equina deficits. The treatment is challenging. Between 2006 and 2009, we treated nine such patients at our trauma centre. There were six men and three women, with a mean age of 32.2 years. Preoperative neurologic deficits were noted in seven patients; four patients had complete cauda equina paralysis, and three patients had incomplete cauda equina syndrome. All patients were treated using lumbopelvic instrumented fixation without other devices for their multiplanar sacral fractures. Six patients who had neurological deficits and sacral canal compression underwent decompression laminectomy. The mean postoperative follow-up time was 21.7 months (range, 14-32 months). All fractures went on to union without loss of reduction or hardware failure. The mean Gibbons score improved from 3.5 preoperatively to 2.3 postoperatively among the patients who underwent decompression laminectomy. Eight out of nine patients had fair or better results based on radiographic criteria and the Majeed pelvic fracture outcome score. Our experience suggests lumbopelvic fixation can be used for the treatment of multiplanar sacral fractures with spinopelvic instability with a low rate of complications. Neurologic improvement can be expected, but whether surgical decompression results in substantially better neurologic recovery than conservative treatment remains uncertain.

[Operative treatment of the scapular fractures through modified Judet approach].

OBJECTIVE: To investigate the effect of operative treatment of scapular fractures through modified Judet approach. METHODS: From January 1997 to October 2005, 21 patients (15 females, 6 males; mean age 34 years) of scapular fractures were treated by open reduction and internal fixation through the modified Judet approach. According to Hardegger classification system, there were 11 patients of scapular body fractures, 10 patients of scapular neck fractures, 8 patients of glenoid rim fractures, 7 patients of glenoid fossa fractures, 9 patients of scapular spine fractures, and 6 patients of scapular acromion fractures. RESULTS: Eighteen patients were followed up with an average of 21 months (range 6 months-4 years). According to Rowe scores system, 12 patients showed excellent, 3 showed good, 2 showed fair, and 1 showed poor. CONCLUSIONS: The modified Judet approaches have the advantages of wide exploration, safety, and easy fixation. It is a good choice to the operation for most types of scapular fractures through the modified Judet approach.
