Percutaneous posterior fixation for unstable pelvic ring fractures.

Several posterior fixation techniques for unstable pelvic ring fractures have been described. Here, we present a minimally invasive, percutaneous technique to fix the two posterior iliac crests using spinal instrumentation. Between September 2008 and March 2012, 11 patients with a mean age of 36.4 years were operated because of a vertically unstable Tile C pelvic ring fracture. Posterior fixation was performed using two polyaxial screws in each iliac crest with two subfascial connector rods. At the final follow-up, all patients were evaluated clinically and radiologically. The mean surgery time was 45 minutes; there were no intraoperative complications. At a mean follow-up of four years, the functional Majeed score was excellent in eight patients and good in three patients. The radiological results were excellent in eight patients and good in three patients. Percutaneous posterior fixation of vertically unstable pelvic fractures leads to good functional and radiological outcomes. TYPE OF STUDY: Technical note, retrospective. LEVEL OF EVIDENCE: IV.

Traumatic avulsion of the flexor digitorum profundus tendon. Jersey finger, a 29 cases report.

Traumatic avulsion of flexor digitorum profundus (jersey finger) is an uncommon injury. Our study aimed to describe functional outcomes of jersey fingers after surgical treatment. From January 2004 to 2014, we performed surgery on 32 patients who had jersey finger. Twenty-six of these patients were male and 6 were female with a mean age of 37.2years (range 16-68). Of the 32 cases, 11 were sports injuries, 16 presented on the ring finger and 13 on the little finger. Using the Leddy and Packer and Smith classifications, 16 of the injuries were type I, 4 were type II, 5 were type III, 7 were type IV. The mean time between injury and surgery was 6.8days (range: 0-32). The surgical techniques used were anchor, pull-out, or an association of both these techniques. Prior to the patient discharge, functional outcomes were evaluated. Twenty-nine patients were evaluated in total and three patients were lost. Of the 29, the average time between surgery and discharge was 36.6months ranging from 4.5 to 118months. According to the Buck-Gramcko classification, six patients had an excellent result, six had a good result, seven had a satisfactory result and ten a poor result. The mean Quick DASH score immediately to prior discharge was 5.66 (range: 0-56.82). Twelve complications were reported on nine patients. No infections were reported. Rapid diagnosis and rapid surgical treatment led to restoration of full range motion.

Surgical repair of massive rotator cuff tendon tears: Autologous quadriceps tendon graft versus arthroscopic repair.

INTRODUCTION: Massive rotator cuff tear repair results are variable. The main purpose of this study was to compare functional outcome between two procedures: open repair by autologous quadriceps-patella tendon patch, and arthroscopic suture. The study hypothesis was that there is no significant difference in results between the two techniques. MATERIAL AND METHODS: A retrospective study included all patients younger than 70 years operated on from 1995 to 2013 for massive rotator cuff tear. Exclusion criteria comprised history of dislocation, fracture or surgery or osteoarthritis in the affected shoulder, and infra- and supra-spinatus fatty degeneration equal to or greater than stage 3. Two consecutive groups were distinguished: group 1, from 1995 to 2003, comprised 23 patients (24 shoulders; mean age, 55.8 years) treated by open repair using quadriceps tendon autograft; group 2, from 2003 to 2013, comprised 27 patients (29 shoulders: mean age, 60.3 years) treated by arthroscopic repair. RESULTS: Preoperatively, mean Constant score was 42.9 in group 1 and 45.7 in group 2 (P=0.36), pain score 5.5/15 and 7.6/15 (P=0.08), strength 3.0kg and 2.4kg (P=0.30), and subacromial space 6.3 and 6.7mm (P=0.05), respectively. At respectively 58 and 55 months' mean follow-up, Constant score was 71.1 in group 1 and 71.8 in group 2 (P=0.086), pain 11.9/15 and 12.7/15 (P=0.76), gain in strength 1.4kg and 2.3kg (P=0.0006), and subacromial space 7.1mm and 6.3mm (P=0.29), respectively. The complications rate was 70% in group 1 and there were no specific complications in group 2. CONCLUSION: Functional improvement was significant and comparable between the 2 groups. Quadriceps tendon harvesting was associated with high morbidity, but the technique increased subacromial space. LEVEL OF EVIDENCE: IV, retrospective, single-center.
