The aim of this prospective study was to determine the usefulness of a gravity stress view in detecting instability in isolated Weber B fractures of the fibula. We used a standard protocol for patient selection, exclusion, surgery/conservative management and follow-up. Open fractures, fracture dislocations, those with medial/posterior malleolus fractures and those with preliminary X-rays showing a talar shift/tilt were excluded. If the medial clear space increased beyond 4mm on stress radiographs, surgical reduction and fixation of the lateral malleolus was performed. If this remained 4mm or less conservative treatment was undertaken. We followed these patients at 2, 4, 6 and 12 weekly intervals.Purpose
Materials and methods
Two patients had re operation due to poor intra operative reduction which were performed by junior grade surgeon without supervision during out of hours. No fracture had displaced at follow up when compared with the intra operative X-ray when properly reduced and wired. One child had ulnar neuropraxia post operatively One child had superficial infection, which settled with oral antibiotics.
New guidelines proposed:
Patients with no N-V complications can wait till the morning trauma list. All intraoperative X-rays to be reviewed by consultants before discharging home. 3 weeks appointment for wire removal can be set at one week clinic follow up with out X-ray.
ASA 2: 66 patients mean age 82 years – MTS 6.3, comorbities 1.8, average time to theatre 36 hours. 15% had injury/implant related complications, one year mortality rate was 4.5%. ASA 3: 64 patients mean age of 84 years – MTS 3.9, comorbidities 2.7, average time to theatre of 3 days. 6.25% had injury specific complications, one- year mortality rate was 28.13%. ASA grade 4: 6 Patients mean age 83 years – MTS 5, comorbidities 3. The one-year mortality rate was 83.33%. Four patients were medically unfit to undergo any form of surgical intervention. Overall 9% of patients had complications related to the injury/implant that occurred exclusively in ASA 2 and 3 groups and the one year mortality rate was 17.22% for the entire group.
Data collected included a Visual analogue pain score (VAS), analgesic requirement in the immediate postoperative period, activity score and oxford hip score at a minimum of six months follow up. Radiographs were assessed independently and blinded for technique, assessing implant position and quality of cementation using Barrack and Charnley and DeLee classifications.
There was a statistically significant difference in the scar length between the two groups (p<
0.05). There were no intra-operative complications in study groups.
