Extended lateral approach for intra-articular calcaneal fractures: an inverse relationship between surgeon experience and wound complications.

The current reference standard for the treatment of displaced intra-articular calcaneal fractures is open reduction and internal fixation using an extended lateral approach. In the present retrospective study, we evaluated the results of a consecutive series of patients treated in the same fashion from June 2005 to September 2011 using a subcuticular single-layer closure technique. We also determined the risk factors for the development of wound complications and the rate of wound complications. Also, we assessed which patient, fracture, and surgical characteristics affected these complications. During the 75-month study period, we operated on 53 displaced intra-articular calcaneal fractures in 50 patients using the extended lateral approach. The incision was closed using the subcuticular technique in 49 cases (92.45%). In the subcuticular closure group 2 (4.1%) deep infections and 2 (4.1%) superficial wound complications (1 dehiscence and 1 infection) occurred. Wound edge or flap necrosis was not encountered. The use of bone-void filler and the experience of the surgical team were significantly (p < .001 and p = .026, respectively) associated with the occurrence of wound complications. The subcuticular single-layer suture technique is a suitable closure technique in the treatment of displaced intra-articular calcaneal fractures. It was associated with a low complication rate combined with the extended lateral approach. The effect of bone void fillers on the incidence of complications should receive more attention in future research. The association between wound complications and the experience level of the surgical team supports the need for centralization of this complex injury.

Humeral shaft fractures: retrospective results of non-operative and operative treatment of 186 patients.

BACKGROUND: Humeral shaft fractures account for 1-3% of all fractures and 20% of the fractures involving the humerus. The aim of the current study was to compare the outcome after operative and non-operative treatment of humeral shaft fractures, by comparing the time to radiological union and the rates of delayed union and complications. METHODS: All patients aged 16 years or over treated for a humeral shaft fracture during a 5-year period were included in this retrospective analysis; periprosthetic and pathological fractures were excluded. Radiographs and medical charts were retrieved and reviewed in order to collect data on fracture classification, time to radiographic consolidation and the occurrence of adverse events. RESULTS: A total of 186 patients were included; 91 were treated non-operatively and 95 were treated operatively. Mean age was 58.7 ± 1.5 years and 57.0% were female. In 83.3% of the patients, only the humerus was affected. A fall from standing height was the most common cause of the fracture (72.0%). Consolidation time varied from a median of 11-28 weeks. The rate of radial nerve palsy in both groups was similar: 8.8% versus 9.5%. In 5.3% of the operatively treated patients, the palsy resulted from the operation. Likewise, delayed union rates were similar in both groups: 18.7% following non-operative treatment versus 18.9% following surgery. CONCLUSION: The data indicated that consolidation time and complication rates were similar after operative and non-operative treatment. A prospective randomised clinical trial comparing non-operative with operative treatment is needed in order to examine other aspects of outcome, meaning shoulder and elbow function, postoperative infection rates, trauma-related quality of life and patient satisfaction.

The management of acute distal tibio-fibular syndesmotic injuries: results of a nationwide survey.

INTRODUCTION: Ankle fractures are one of the most frequently encountered musculoskeletal injuries, and 10% of patients have a concomitant distal tibiofibular syndesmotic disruption necessitating surgical repair. A national survey was conducted to gain more insight into the current approaches in the management of syndesmotic injuries in the Netherlands. MATERIALS AND METHODS: A postal survey was sent to one or two staff members of the trauma and orthopaedic surgery departments in each of the 86 hospitals in the Netherlands. Questions concerned the pre-, per- and postoperative strategies and the different ideas on the type, number and placement of the syndesmotic screw. RESULTS: A total of 85.2% of the trauma surgeons and 61.9% of the orthopaedic surgeons responded (representing 87% of all hospitals). Syndesmotic injury was judged mainly using the 'Hook test'. Syndesmotic injuries in a Weber-B ankle fracture were treated with one screw in 81.2% of cases and in Maisonneuve injuries mainly with two screws. The 3.5-mm screw was used most frequently over three cortices at 2.1-4.0cm above the tibial plafond. Removal of the syndesmotic screw was routinely done by 87.0% of surgeons, mostly between 6 and 8 weeks. Of all respondents, 62.3% showed interest in participating in a randomised controlled trial comparing standard removal with removal on indication. CONCLUSION: Compared with previous surveys our survey is more complete, has the highest response rate and has almost national coverage. Most individual items reviewed compare well with current literature, except for the routine removal of the syndesmotic screw, which might not be encouraged from a literature point of view. For this reason, the results of the current survey will be used in the development of a multicentre randomised controlled trial comparing the functional outcome in routine removal of the syndesmotic screw compared with removal on indication.

Hemi-Castaing ligamentoplasty for the treatment of chronic lateral ankle instability: a retrospective assessment of outcome.

PURPOSE: In the treatment of chronic ankle instability, most non-anatomical reconstructions use the peroneus brevis tendon. This, however, sacrifices the natural ankle stabilising properties of the peroneus brevis muscle. The aim of this study was to evaluate the functional outcome of patients treated with a hemi-Castaing procedure, which uses only half the peroneus brevis tendon. METHODS: We performed a retrospective cohort study of patients who underwent hemi-Castaing ligamentoplasty for chronic lateral ankle instability between 1993 and 2010, with a minimum of one year follow-up. Patients were sent a postal questionnaire comprising five validated outcome measures: Olerud-Molander Ankle Score (OMAS), Karlsson Ankle Functional Score (KAFS), Tegner Activity Level Score (pre-injury, prior to surgery, at follow-up), visual analog scale on pain (VAS) and the Short Form 36 (SF-36). RESULTS: Twenty patients completed the questionnaire on functional outcome. The OMAS showed good to excellent outcome in 80% and the KAFS in 65%, the Tegner Score improved from surgery but did not reach pre-injury levels, the VAS on pain was 1 of 10 and the SF-36 returned to normal compared with the average population. CONCLUSIONS: Even though most patients were satisfied with the results, outcome at long-term follow-up was less favourable compared with the literature on anatomical reconstructions. In accordance with the literature, we therefore conclude that the initial surgical treatment of chronic lateral ankle instability should be an anatomical repair with augmentation (i.e. the Broström-Gould technique) and the non-anatomical repair should be reserved for unsuccessful cases after anatomical repair or in cases where no adequate ligament remnants are available for reconstruction.

Subtalar versus triple arthrodesis after intra-articular calcaneal fractures.

Depending upon initial treatment, between 2 and 30% of patients with a displaced intra-articular calcaneal fracture require a secondary arthrodesis. The aim of this study was to investigate the effect of subtalar versus triple arthrodesis on functional outcome. A total of 33 patients with 37 secondary arthrodeses (17 subtalar and 20 triple) with a median follow-up of 116 months were asked to complete questionnaires regarding disease-specific functional outcome (Maryland Foot Score, MFS), quality of life (SF-36) and overall satisfaction with the treatment (Visual Analogue Scale, VAS). Patient groups were comparable considering median age at fracture, initial treatment (conservative or operative), time to arthrodesis, median follow-up, and post-arthrodesis radiographic angles. The MFS score was similar after subtalar versus triple arthrodesis (59 vs. 56 points; P = 0.79). No statistically significant difference was found for the SF-36 (84 vs. 83 points; P = 0.67) and the VAS (5 vs. 6; P = 0.21). Smoking was statistically significantly associated with a non-union (χ(2) = 6.60, P = 0.017). The current study suggests that there is no significant difference in functional outcome between an in situ subtalar or triple arthrodesis as a salvage technique for symptomatic arthrosis after an intra-articular calcaneal fracture. Smoking is a risk factor for non-union.

Long-term functional and quality of live assessment following post-traumatic distraction osteogenesis of the lower limb.

Limb length discrepancy and segmental bone defects can be difficult problems to manage after fractures of the lower limb. Distraction osteogenesis can be applied to lengthen bone or to bridge intercalary defects by segmental bone transport. The purpose of this study was to assess the functional outcome and long-term quality of life after distraction osteogenesis of the lower limb when applied for post-traumatic problems. Three patients were treated with segmental transport for bone loss secondary to infection and debridement after a tibia fracture. Leg lengthening was performed in 12 patients with consolidated fractures (eight femurs and four tibias). Long-term functional outcomes were evaluated with the Short Form-36 Health Survey (SF-36) and the Lower Extremity Functional Scale (LEFS) in all patients. The mean follow-up was 9 years. Functional outcomes indicated moderate difficulty in patients after segmental transport and a little difficulty in patients after lengthening of consolidated fractures. The SF-36 scores varied two points for physical functioning and one point for bodily pain as compared to the SF-36 norm-based scores. In all other six domains, patient scores were comparable with the general population. In conclusion, the quality of life and functional outcome returned to normal after post-traumatic distraction osteogenesis of the lower limb.

Percutaneous reduction and fixation of intraarticular calcaneal fractures.

OBJECTIVE: Percutaneous reduction by distraction and subsequent percutaneous screw fixation to restore calcaneal and posterior talocalcaneal facet anatomy. The aim of this technique is to improve functional outcome and to diminish the rate of secondary posttraumatic arthrosis compared to conservative treatment and, secondly, to reduce infectious complications compared to open reduction and internal fixation (ORIF). INDICATIONS: Sanders type II-IV displaced intraarticular calcaneal fractures. CONTRAINDICATIONS: Isolated centrally depressed fragment. Patients who are expected to be noncompliant. SURGICAL TECHNIQUE: Four distractors (Synthes) are positioned, two on each side of the foot, between the tuberosity of the calcaneus and talus and between the tuberosity and cuboid. A distracting force is given over all four distractors. A blunt drifter is then introduced from the plantar side to unlock and push up any remaining depressed parts of the subtalar joint surface of the calcaneus. The reduction is fixated with two or three screws inserted percutaneously. POSTOPERATIVE MANAGEMENT: Directly postoperatively, full active range of motion exercises of the ankle joint can start, with the foot elevated in the 1st postoperative week. Stitches are removed after 14 days. Implant removal is necessary in 50-60% of patients. RESULTS: Between 1999 and 2004, 59 patients with 71 fractures were treated by percutaneous skeletal triangular distraction and percutaneous fixation. A total of 50 patients with 61 fractures and a minimum follow-up of 1 year were available for follow-up. According to the American Orthopaedic Foot and Ankle Society Hindfoot Score, 72% had a good to excellent result. A secondary subtalar arthrodesis was performed in five patients and planned in four (total 15%). Böhler's angle increased by about 20 degrees postoperatively. Sagittal motion was 90% and subtalar motion 70% compared to the healthy foot.

Percutaneous treatment of displaced intra-articular calcaneal fractures.

BACKGROUND: The outcome after displaced intra-articular calcaneal fractures is influenced by the condition of the surrounding soft tissues. To avoid secondary soft tissue complications after surgical treatment, several less-invasive procedures for reduction and fixation have been introduced. The percutaneous technique according to Forgon and Zadravecz is suitable for all types of displaced intra-articular calcaneal fractures and was therefore introduced in our clinic. The aim of this study was to evaluate the long-term outcome of percutaneous treatment according to Forgon and Zadravecz in patients with displaced intra-articular calcaneal fractures. METHODS: A cohort of patients with displaced intra-articular calcaneal fractures treated with percutaneous surgery was retrospectively defined. Clinical outcome was evaluated by standardized physical examination, radiographs, three published outcome scores, and a visual analogue scale of patient satisfaction. RESULTS: Fifty patients with 61 calcaneal fractures were included. After a mean follow-up period of 35 months, the mean values of the Maryland foot score, the Creighton-Nebraska score, and the American Orthopaedic Foot and Ankle Society score were 79, 76, and 83 points out of 100, respectively. The average visual analogue scale was 7.2 points out of 10. The average range of motion of the ankle joint was 90% of normal and subtalar joint movements were almost 70% compared with the healthy side or normal values. Superficial wound complications occurred in seven cases (11%) and deep infections in two (3%). A secondary arthrodesis of the subtalar joint was performed in five patients and was scheduled in four patients (15%). CONCLUSIONS: Compared with the outcome of historic controls from randomized trials and meta-analyses, this study indicates favorable results for the percutaneous technique compared with the open technique. Despite similar rates of postoperative infection and secondary arthrodesis, the total outcome scores and preserved subtalar motion are overall good to excellent.
