ABSTRACT
BACKGROUND: The purpose of the present study was to evaluate the results of the Sheffield bone block procedure for anteroinferior bone loss in traumatic shoulder instability. In this modified open technique, the medial half of coracoid process without its soft tissue attachments is used to provide congruent augmentation of the anteroinferior glenoid and secured with two screws. METHODS: In this retrospective consecutive case series (2007-11), all patients having recurrent traumatic instability with glenoid bone loss > 20% and/or a large Hill-Sachs lesion were included. The shoulder function was evaluated clinically and by Oxford Shoulder Instability Score (OSIS; by post/telephone). RESULTS: There were 84 patients in this series with a large proportion engaged in contact sports. Mean (range) age was 33 years (16 years to 45 years); male : female, 59 : 8; mean (range) follow-up period was 48 months (36 months to 84 months) and the response rate 89% (75/84). Mean postoperative OSIS was 43 (33 to 46) and one patient had re-dislocation (1.3%). No neurovascular complications/hardware failure/non-union/infections were noted. By 6 months, 85% patients had returned to pre-injury sport and 93% had returned to pre-injury work. CONCLUSIONS: The Sheffield bone block procedure provides reliable and satisfactory results in patients having recurrent instability with glenoid bone loss and/or a large Hill-Sachs lesion with minimal complications and an excellent chance of returning to original sport and occupation.
ABSTRACT
BACKGROUND: The TightRope® is a relatively new device designed to stabilize ankle syndesmotic injuries. There are no studies evaluating the clinical effectiveness of this technique and few reports addressing complications and potential modifications to the surgical technique reported in this article. MATERIALS AND METHODS: A retrospective review of 102 cases of traumatic ankle syndesmotic stabilization using the TightRope device is presented. Patients were followed up for a median of 85 days after surgery. RESULTS: Eight patients subsequently had the TightRope removed. This was performed for four reasons: osteomyelitis surrounding the implant, painful aseptic osteolysis surrounding the implant, failed stabilization of the syndesmosis, and unexplained pain. CONCLUSIONS: On the basis of experience, the authors recommend meticulous attention during the surgical technique. To prevent skin irritation and stitch abscess formation leading to osteomyelitis, the FiberWire loop is best cut with a knife at least 1 cm beyond the knot, allowing the sharp end of the FiberWire to lay flat adjacent to the fibula. Painful aseptic osteolytic reaction to the TightRope necessitates removal. To prevent rediastasis, a small medial incision is recommended for endobutton positioning directly abutting the tibial cortex without soft tissue interposition. Inserting the TightRope through a fibula plate prevents lateral button pull-through and rediastasis.
