Patients and Methods: Between December 2005 until January 2008 34 distal humerus fractures in 33 patients were prospectively documented and treated using the angular-stable LCP distal humerus plate system from Synthes/Switzerland. Patient median age was 54 (min 14/ max 88). Fracture types were classified according to the AO classification. Extraarticular A fractures were documented in 3 (9%) cases, partial intra-articular fractures (type B) were seen in 4 (12%) patients. Complete intraarticular fractures were found in 27 (79%) cases. Three fractures were grade I° open, 6 fractures were grade II° open according to the Gustilo classification. In median after 10 months (min 8/ max 20) follow up was performed. Due to lost to follow up in one patient functional outcome was measured in 32 patients. Functional results were evaluated using the Mayo Elbow Performence Score (MEPS).

Results: According to MEPS, predominantly excellent and good results were achieved. The intent of stable fracture fixation to allow early physical therapy was reached in 31 patients. Failure of osteosynthesis making operative revision necessary occurred in 3 patients (1x implant failure, 2x loss of reduction). Mean Mayo Elbow Performance Score was 91 points (min 88.5/ max 100). Mean range of motion for extension/flexion was 110° (min 80/ max 140) and 170° (min 125/max 180) for pronation/supination. Only one patient regained unrestricted extension, mean loss of extension was 21° (min 10/ max 40). Mean Flexion up to 131° was achieved (min 125/ max 140).

Postoperative complications were seen in eight cases (implant breakage, delayed union, lost of reduction).

Conclusion: Despite postoperative complications and revision surgery, functional results achieved using the angular-stable LCP distal Humerus system are good or excellent in the majority of patients. Through angular-stable and multidirectional screw options fixation of the distal fragment is sufficient and periostal blood supply could be protected. Especially in combination of intraarticular fractures and osteoporotic bone stock the use of the LCP distal Humerus plate system is suitable and permits early physical therapy, promising a benefit for the elbow function.

Introduction: This study is a retrospective review of patients who underwent corticosteroid spinal injections and/or surgery for lumbar juxtafacet cysts to determine the effectiveness of corticosteroid injection and/or surgery for the treatment of lumbar juxtafacet cysts.

Methods: The charts of 40 patients who underwent corticosteroid injection and/or surgery for the treatment of symptomatic juxtafacet cysts were reviewed and an outcome questionnaire was sent to each patient. All patients responded to the questionnaire (100%).

Results: Forty-four juxtafacet cysts were treated in 40 patients. 28 cysts were initially treated with corticosteroid injection. 18 facet joints adjacent to the cysts were injected (4 were injected on two or more occasions), 13 underwent epidural injection and 5 underwent nerve sheath exit foraminal blocks. 18 obtained no Benefit from the use of corticosteroid injections and proceeded to surgical treatment. Of the 10 patients that did not undergo surgery, at follow-up 2 reported no clinical change and were considering surgical treatment. This represents a 71% failure rate for non-operative treatment with corticosteroid injections.

34 cysts were resected from 31 patients. Two (6%) were ligamental and 32 were facetal. 31 cysts were resected by laminectomy alone and 3 patients underwent laminectomy and bone only fusion. One cyst (3%) recurred and was managed by repeat laminectomy. One patient required instrumented lumbosacral fusion for increasing anterolisthesis. Incidental dural tear was the most common surgical complication occurring in two cases (6%). One patient demonstrated significant weakness of ankle and foot dorsiflexion which recovered incompletely. Average follow-up for the surgical group was 18 months (5–72 months). 27 scored an excellent or good outcome (79%), 3 scored a fair outcome, 3 were considered poor and one patient was worse. 30 (88%) patients were satisfied having complete improvement or improved with residual back or leg symptoms. Three responded as no change and one was worse.

Discussion: Juxtafacet cysts are an uncommon cause of radiculopathy. Corticosteroid injection into the adjacent facet joints, epidural space or exit foraminae of the spine produces disappointing results. Surgical resection is the treatment of choice with low rates of complications, recurrences and residual complaints.
