Long-term outcomes after different types of Horne and Tanzer olecranon fractures.

BACKGROUND: It is unclear whether the outcomes differ after different Horne and Tanzer types of olecranon fractures. MATERIALS AND METHODS: We evaluated 40 men and 55 women with isolated olecranon fractures, journals and radiographs from fracture event. The fractures were classified according to Horne and Tanzer. After a mean 19 years after the fracture events, we evaluated subjective, clinical and radiographic outcomes, using the uninjured arms as controls. RESULTS: 95% of patients with type I fractures reported, at follow-up, no differences between the elbows, 80% with type II fractures and 95% with type III fractures (p = 0.43). The three types of fractures had no differences in elbow range of motion or hand grip strength (when comparing injured and uninjured arms) and the proportions of individuals with radiographic elbow degenerative changes or joint space reduction were no different (all p > 0.05). Individuals with elbow degenerative changes had no inferior subjective elbow function compared to individuals with normal radiographs (p = 0.66), in contrast to those with joint space reduction compared to individuals with normal radiographs (p < 0.001). INTERPRETATION: All types of Horne and Tanzer olecranon fractures have favourable long-term outcome. Elbow joint space reduction is associated with inferior subjective elbow function while degenerative changes are not.

Treatment of radius or ulna fractures in the elderly: A systematic review covering effectiveness, safety, economic aspects and current practice.

BACKGROUND: The objective of the present study was to evaluate effectiveness, complications and cost-effectiveness of any surgical or non-surgical treatment for radius or ulna fractures in elderly patients. Secondary objectives were to analyze present treatment traditions of distal radius fractures (DRF) in Sweden and to calculate resource usage for its treatment. METHODS AND FINDINGS: The assessment contains a systematic review of clinical and health economic studies comparing treatment options for radius or ulna fractures. The results regarding the effectiveness of the treatments are summarized in meta-analyses. In addition, the assessment contains a cost analysis for different treatment options commonly used for DRF care, and an analysis of registry data on the incidence and treatment of DRF. In total 31 randomized controlled trials were included in meta-analyses. When comparing functional outcome for plate fixation versus non-surgical treatment for DRF, there were no clinically important differences at one-year follow-up (mean difference [MD], -3.29, 95% CI, -7.03; 0.44). Similar results were found when comparing plating and percutaneous methods with respect to functional outcome (standardized mean difference [SMD], -0.07, 95% CI, -0.21; 0.07) and grip strength (MD, -3.47, 95% CI, -11.21; 4.28). There were no differences for minor complications, (risk difference [RD], -0.01, 95% CI, -0.07; 0.05) whereas major complications were less common for the percutaneous group, (RD, 0.02, 95% CI, 0.02; 0.03). Given the low number of studies, the evidence above was rated as moderate certainty. The cost for plate fixation versus plaster cast was estimated to 1698 compared to 137 US dollars. For DRF, plate fixation increased in Sweden between 2005 and 2013, and was the most common surgical method in 2013. CONCLUSIONS: Surgical treatment of moderately displaced distal radius fractures in elderly patients offers no clear benefit compared to non-surgical treatment. Plating procedures have become more common during the second millennium and involve higher costs and higher risk of major complications than percutaneous options.

Treatment of humerus fractures in the elderly: A systematic review covering effectiveness, safety, economic aspects and evolution of practice.

OBJECTIVES: The objective of this Health Technology Assessment was to evaluate effectiveness, complications and cost-effectiveness of surgical or non-surgical treatment for proximal, diaphyseal or distal fractures of the humerus in elderly patients. Secondary objectives were to evaluate the intervention costs per treatment of proximal humerus fractures (PHF) and to investigate treatment traditions of PHF in Sweden. METHODS AND FINDINGS: The assessment contains a systematic review of clinical and health economic studies comparing treatment options for humerus fractures in elderly patients. The results regarding the effectiveness of treatments are summarized in meta-analyses. The assessment also includes a cost analysis for treatment options and an analysis of registry data of PHF. For hemiarthroplasty (HA) and non-operative treatment, there was no clinically important difference for moderately displaced PHF at one-year follow-up regarding patient rated outcomes, (standardized mean difference [SMD]) -0.17 (95% CI: -0.56; 0.23). The intervention cost for HA was at least USD 5500 higher than non-surgical treatment. The trend in Sweden is that surgical treatment of PHF is increasing. When functional outcome of percutaneous fixation/plate fixation/prosthesis surgery and non-surgical treatment was compared for PHF there were no clinically relevant differences, SMD -0.05 (95% CI: -0.26; 0.15). There was not enough data for interpretation of quality of life or complications. Evidence was scarce regarding comparisons of different surgical options for humerus fracture treatment. The cost of plate fixation of a PHF was at least USD 3900 higher than non-surgical treatment, costs for complications excluded. In Sweden the incidence of plate fixation of PHF increased between 2005 and 2011. CONCLUSIONS: There is moderate/low certainty of evidence that surgical treatment of moderately displaced PHF in elderly patients has not been proven to be superior to less costly non-surgical treatment options. Further research of humerus fractures is likely to have an important impact.

A radial head prosthesis appears to be unnecessary in Mason-IV fracture dislocation.

Background and purpose - Previous reports on elbow injuries with concomitant comminute radial head fracture are difficult to interpret, since they include an array of different soft-tissue and bony injuries around the elbow. We focused on Mason-IV fracture dislocations of the elbow and retrospectively reviewed 2 treatment options: radial head resection or replacement with a radial head arthroplasty, both in combination with lateral ligament repair. Patients and methods - In Linköping, 18 consecutive patients with Mason-IV fracture dislocation and with a median age of 56 (19-79) years were treated with a radial head arthroplasty. In Malmö, 14 consecutive patients with a median age of 50 (29-70) years were treated for the same injury with radial head resection. With a follow-up of at least 2 years (Linköping: median 58 months; Malmö: median 108 months), the outcome was assessed using the Mayo elbow performance score (MEPS), the Disabilities of Arm, Shoulder, and Hand questionnaire (DASH), range of movement, instability, and plain radiographs. Results - There was no statistically significant difference between the groups regarding MEPS, DASH, or range of motion. The rate of additional surgery was higher in patients treated with arthroplasty. Ulno-humeral osteoarthritis was more pronounced in the group treated with radial head resection, but the follow-up time was longer in these patients. Functional results and range of motion tally well with previous reports on similar injuries. Interpretation - Functional results did not improve by using a press-fit radial head arthroplasty in Mason-IV fracture dislocation of the elbow. Secondary osteoarthritis after resection of the radial head is a concern, but it did not affect the functional outcome during the follow-up time.

Acute Achilles tendon rupture: a questionnaire follow-up of 487 patients.

BACKGROUND: The optimum treatment of acute total Achilles tendon rupture remains controversial. In the present study, the outcomes of surgical and nonsurgical treatment in a large number of patients were compared on the basis of patient age and sex. METHODS: The records of all 487 patients with an acute total Achilles tendon rupture that had occurred between 2002 and 2006 and had been treated at one of two university hospitals in Sweden were manually reviewed. Surgical treatment was primarily used at Hospital 1, whereas nonoperative functional treatment was primarily used at Hospital 2. At one to seven years after the rupture, the majority of the patients were evaluated for complications, the Achilles Tendon Total Rupture Score was calculated, a heel-raise test was performed, and calf circumference was measured. The outcomes of surgical and nonsurgical treatment were compared on the basis of patient age and sex. RESULTS: The mean age at the time of the injury was forty-five years. In the surgical treatment group at Hospital 1, six (3%) of 201 patients had a re-rupture and three (1.5%) had an infection. In the nonsurgical treatment group at Hospital 2, the rate of re-rupture rate was 6.6% (fifteen of 227). When the results for the surgical treatment group at Hospital 1 were compared with those for the nonsurgical treatment group at Hospital 2, there was no significant difference in terms of the mean Achilles Tendon Total Rupture Score (81.7 compared with 78.9; p = 0.1), but both the difference in the heel-raise test (p = 0.01) and the difference in calf circumference (1.4 compared with 2.0 cm; p = 0.01) reached significance in favor of surgery. Nonsurgically managed female patients showed significant worsening of the Achilles Tendon Total Rupture Score and heel-raise test with increasing age at the time of injury. CONCLUSIONS: The good Achilles Tendon Total Rupture Score in the nonsurgically managed group, together with the relatively low rate of re-ruptures and other complications in these patients, makes this treatment a preferable option for most patients. However, the tendency for a lower re-rupture rate and better performance on the heel-raise test in surgically treated patients suggest surgery may be beneficial in selected patients.

Comminuted fractures of the radial head.

BACKGROUND: There have been few reports on the long-term outcome of comminuted radial head fractures in adults. METHOD: 10 women and 9 men with a mean age of 45 (21-65) years when they sustained a comminuted fracture of the radial head were re-evaluated after 15-25 years. 6 patients had been nonoperatively (NO) treated while 13 had had a radial head excision. The uninjured elbow served as a control. RESULTS: At follow-up, 11 patients (4 NO patients) rated their fractured elbow as being without deficits, 7 (1 NO) as being slightly impaired, and 1 (NO) as being severely impaired. Range of motion and elbow strength were not impaired, and even though there were more degenerative changes such as cysts, osteophytes, and sclerosis in the injured elbows by radiography, the prevalence of joint space reduction was not higher. INTERPRETATION: Most patients with an isolated comminuted fracture of the radial head treated nonoperatively or with a radial head excision report no or only minor long-term complaints.

Long-term outcome of displaced radial neck fractures in adulthood: 16-21 year follow-up of 5 patients treated with radial head excision.

BACKGROUND: There have been no reports on the long-term outcome of radial neck Mason type IIIb fractures in adults. METHODS: 3 women and 2 men, aged 46 (22-69) years when they sustained a radial neck Mason type IIIb fracture, were evaluated after an average of 18 (16-21) years. All had been treated with radial head excision. RESULTS: 3 individuals had no subjective elbow complaints while 2 reported occasional weakness. None had severe elbow complaints. The maximum elbow-to-elbow difference in range of motion was a deficit of mean 10 degrees in extension in the injured elbow. Mean deficits in elbow flexion, forearm pronation, and forearm supination were below 5 degrees and the mean difference in cubitus valgus angle was only 2 degrees. There was no instability and no recurrent elbow dislocations. Radiographically, there were cysts, sclerosis, and osteophytes in all formerly injured elbows but none in the uninjured elbows. We found reduced joint space in 1 elbow that had been formerly injured. INTERPRETATION: Mason type IIIb fracture in adults, treated with radial head excision, appears to have a favorable long-term outcome.

Primary nonoperative treatment of moderately displaced two-part fractures of the radial head.

BACKGROUND: Moderately displaced two-fragment fractures of the radial head have been treated predominantly nonoperatively. Recently, however, open reduction and internal fixation has gradually gained interest, without clear evidence that initial nonoperative treatment leads to an unfavorable outcome. As a consequence, the purpose of the present study was to evaluate the long-term outcome after the initial nonoperative treatment of this type of fracture. METHODS: Fifteen men and thirty-four women, with a mean age of forty-nine years at the time of the injury, were included in the study. All patients initially had been managed nonoperatively for a two-fragment fracture of the radial head that was displaced 2 to 5 mm and that included >/=30% of the joint surface (a Mason type-IIa fracture). Early mobilization had been used for twenty-seven patients, and cast immobilization for a mean of two weeks (range, one to four weeks) had been used for twenty-two. All patients were reevaluated with a questionnaire after a mean of nineteen years, and thirty-four also had a clinical and a radiographic evaluation. Six patients had had a delayed radial head excision because of an unsatisfactory primary outcome. RESULTS: Forty of the forty-nine patients had no subjective complaints, eight were slightly impaired as the result of occasional elbow pain, and one had daily pain. Flexion was slightly impaired in the injured elbows as compared with the uninjured elbows (137 degrees +/- 8 degrees compared with 139 degrees +/- 7 degrees ), as was extension (-3 degrees +/- 7 degrees compared with 1 degrees +/- 5 degrees ) and supination (86 degrees +/- 7 degrees compared with 88 degrees +/- 4 degrees ) (p < 0.05 for all comparisons). The prevalence of degenerative changes on radiographs was higher for the injured elbows than for the uninjured elbows (82% [twenty-eight of thirty-four] compared with 21% [seven of thirty-four]; p < 0.01). CONCLUSIONS: The initial nonoperative treatment of Mason type-IIa fractures of the radial head that are displaced by 2 to 5 mm is associated with a predominantly favorable outcome, especially if a delayed radial head excision is performed in the few cases in which the early outcome is unsatisfactory. LEVEL OF EVIDENCE: Therapeutic Level IV.

Displaced Mason type I fractures of the radial head and neck in adults: a fifteen- to thirty-three-year follow-up study.

Undisplaced radial head and neck fractures are consistently described with no long-term deficits. The aim of this study was to evaluate specifically the long-term outcome of displaced Mason type I fractures, which have not previously described. Twenty women and twelve men, with a mean age of 46 years (range, 22-69 years) when they sustained a displaced Mason type I fracture, were reexamined at a mean of 21 years (range, 15-33 years) after injury. All were treated nonoperatively. Twenty-nine individuals had no subjective complaints, whereas three had occasional elbow pain. There was no objective impairment, and none had elbow osteoarthritis, defined as reduced joint space, whereas there was more radiographic degeneration in the formerly fractured elbow than in the uninjured elbow (85% vs 4%, P < .001). We conclude that the long-term results of nonoperatively treated displaced Mason type I fractures of the radial head and neck are predominantly favorable.

Fracture-induced changes in bone turnover: a potential confounder in the use of biochemical markers in osteoporosis.

To examine the short- and long-term bone metabolic effects of fracture assessed by biochemical markers, we utilized a clinical fracture model-proximal tibial osteotomy-and prospectively followed 14 patients. This model of an induced fracture of a major bone gives the advantage of assessing baseline levels prior to fracture. Follow-up occurred at 6-9 weeks, 4-7 months, 9-13 months, and 14-17 months after fracture. Serum was assayed for type 1 procollagen peptide (PICP), total alkaline phosphatase (ALP), and carboxy-terminal-telopeptide of type I collagen (ICTP), while deoxypyridinoline (Dpyr) was measured in urine. Serum osteocalcin (OC) was measured using two recently developed two-site immunofluorometric assays, which both measure full-length and fragmented forms of OC (OCtot), with one of the assays specifically detecting only the carboxylated form of OC (OCcxy). In addition, OC was measured in urine using the same assays as those used for serum. Serum OCtot increased to a peak at 4-7 months after fracture (P < 0.001) and a similar increase was seen for OCcxy (P < 0.05) and ALP (P < 0.01). Bone formation had returned to baseline after a year. Dpyr increased significantly, with a doubling at 6 weeks, while serum (S)-ICTP increased by 73% (P < 0.01 and P < 0.001). Urine OC increased to a maximum of 84% at 6 weeks. The initial percentage increase of bone resorption was greater than that of bone formation. We conclude that: (1) bone turnover as measured by biochemical markers is altered soon after fracture, (2) the major changes occur within 6 weeks to 6 months, but may persist for up to a year. (3) The initial increase in bone resorption exceeds the increase in bone formation, which may contribute to the enhanced bone loss after fracture. (4) The two novel urine OC assays show a similar pattern of change as established marks of bone resorption, which may indicate that they measure bone resorption. (5) Fracture-induced effects on bone turnover are significant and, thus, are potential confounders in the assessment of osteoporosis.

Fractures of the radial head and neck treated with radial head excision.

BACKGROUND: The reported long-term outcomes of the treatment of radial head and neck fractures with excision of the radial head have been mixed. The purpose of the present study was to evaluate the long-term outcomes of primary or delayed radial head excision for the treatment of these fractures. METHODS: Sixty-one individuals (mean age, forty-four years) with thirty-nine Mason type-II, ten Mason type-III, and twelve Mason type-IV fractures were evaluated subjectively, objectively, and radiographically at a mean of eighteen years (range, eleven to thirty-three years) after treatment. Forty-three fractures were treated with primary radial head excision, and the remaining eighteen were treated with delayed radial head excision at a median of five months (range, one to 238 months) after the injury. RESULTS: At the time of follow-up, twenty-eight individuals had no symptoms, twenty-seven had occasional elbow pain, and six had daily pain. Four individuals with daily pain had had a Mason type-IV fracture. The range of motion of the formerly injured upper extremities was slightly less than that of the uninjured upper extremities in terms of flexion (139 degrees +/- 11 degrees compared with 142 degrees +/- 8 degrees ), extension (-7 degrees +/- 12 degrees compared with -1 degrees +/- 6 degrees ), and supination (77 degrees +/- 20 degrees compared with 85 degrees +/- 10 degrees ) (all p < 0.01). A higher percentage of formerly injured elbows than uninjured elbows had cysts, sclerosis, and osteophytes (73% compared with 7%; p < 0.001), but none had a reduced joint space. No differences were found between the outcomes for individuals treated with a primary radial head excision and those for individuals treated with a delayed excision. CONCLUSIONS: Following a displaced radial head or neck fracture, excision of the radial head often leads to a good or fair result. We found no differences in outcome between primary and delayed radial head excisions following a Mason type-II, III, or IV fracture. The outcomes are associated with the type of fracture, with Mason type-IV fractures having the worst results, rather than with the timing of the radial head excision (primary or delayed).

Uncomplicated Mason type-II and III fractures of the radial head and neck in adults. A long-term follow-up study.

BACKGROUND: The purpose of this study was to evaluate the incidence and the long-term results of closed uncomplicated Mason type-II and III fractures in a defined population of adults. METHODS: Seventy women and thirty men who were a mean of forty-seven years old when they sustained a fracture of the radial head or neck (a Mason type-II fracture in seventy-six patients and a Mason type-III fracture in twenty-four) were reexamined after a mean of nineteen years. Radiographic signs of degenerative changes of the elbow were recorded. The fracture had been treated with an elastic bandage or a collar and cuff sling with mobilization for forty-four individuals, with cast immobilization for thirty-four, with resection of the radial head in nineteen, with open reduction of the radial head in two, and with a collateral ligament repair in one. Secondary excision of the radial head was performed because of residual pain in nine patients, and a neurolysis of the ulnar nerve was performed in one patient. RESULTS: Seventy-seven individuals had no symptoms in the injured elbow at the time of follow-up, twenty-one had occasional pain, and two had daily pain. The injured elbows had a slight flexion deficit compared with the uninjured elbows (mean and standard deviation, 138 degrees +/- 8 degrees compared with 140 degrees +/- 7 degrees ) as well as a small extension deficit (mean and standard deviation, -4 degrees +/- 8 degrees compared with -1 degrees +/- 6 degrees ) (p < 0.001 for both). The prevalence of degenerative changes was higher in the injured elbows than in the uninjured ones (76% compared with 16%, p < 0.001). CONCLUSIONS: The results following uncomplicated Mason type-II and III fractures are predominantly favorable. A secondary radial head resection is usually effective for patients with an unfavorable outcome (predominantly long-standing pain). LEVELS OF EVIDENCE: Therapeutic study, Level IV (case series [no, or historical, control group]). See Instructions to Authors for a complete description of levels of evidence.

Fracture of the radial head and neck of Mason types II and III during growth: a 14-25 year follow-up.

Twenty-four individuals, who were 16 years of age or younger when they sustained a fracture of the radial head or neck, were examined at a mean of 19 years (range 14-25 years) after injury. The 12 girls and 12 boys were a mean age of 11 years (range 5-16 years) when the fracture was sustained. Two were excluded due to late resection of the radial head following persisting pain. The fractures, which were of Mason type II in 19 and type III in three cases, were treated by mobilization in eight cases, plaster in eight, open reduction and internal fixation in three and closed reduction and plaster in three. At the follow-up examination, 19 (86%) had no complaints, while three (14%) had occasional pain. Flexion was decreased in the formerly injured compared with the uninjured elbow (139 +/- 8 degrees versus 142+/-5 degrees; P<0.05). None had developed elbow osteoarthritis. Isolated, closed fracture of the radial head and neck during growth has a favourable, long-term outcome.

Fractures of the olecranon: a 15- to 25-year followup of 73 patients.

The incidence of olecranon fractures in adults and the long-term outcome of closed olecranon fractures in 45 women and 28 men (mean age, 54 and 36 years at the time of fracture, respectively), were examined at a mean of 19 years after the fracture. The uninjured elbows served as controls. Thirteen percent of the original fractures were displaced less than 2 mm, 65% more than 2 mm, and 22% were multifragmental. Primary treatment consisted of mobilization in 4%, application of a plaster cast in 12%, and open reduction and internal fixation in 84% of the elbows. The incidence of an isolated fracture of the olecranon in individuals older than 16 years was 1.15 per 10,000 person-years. Eighty-four percent of the 73 patients had no complaints at followup, 12% had occasional pain, and 4% had daily pain. Ninety-six percent had an excellent or good outcome. Elbow flexion and extension were reduced but most patients had no or only occasional subjective complaints. Radiographic signs of degenerative changes were found in more than 50% of the formerly fractured elbows, which was more than in the uninjured (11%). Radiographic signs of osteoarthritis were found in 6% of the formerly fractured elbows versus zero percent in the uninjured, of which only two patients had a poor outcome. Isolated, closed fractures of the olecranon in adults have a favorable, long-term outcome.

Comparison of tension-band and figure-of-eight wiring techniques for treatment of olecranon fractures.

Two different internal fixation techniques for closed displaced fractures of the olecranon were evaluated at a mean of 18 years after injury. Thirty-two of the patients received tension-band wiring, and 35 received figure-of-eight wiring. There were 41 women (mean age, 52 years) and 26 men (mean age, 32 years) included. The results revealed that 80% of the patients had no subjective complaints, 16% had occasional pain, and 4% had daily pain. Comparison of the injured and uninjured elbows demonstrated a 3 degrees reduction of flexion (P <.05) and a 5 degrees loss of extension (P <.01). More than 50% of the fractured elbows had degenerative changes (joint space narrowing, subchondral cysts, subchondral sclerosis, and osteophytes) (P <.001), and 4 had osteoarthritis (P <.05). No subjective, objective, or radiographic differences were found when the two techniques were compared. Removal of the hardware was performed in 81% of the patients with tension-band wiring and in 43% of the patients with figure-of-eight wiring (P <.01). The figure-of-eight technique can, therefore, be recommended, as it is associated with less frequent secondary procedures for hardware removal.

Fractures of the olecranon during growth: a 15-25-year follow-up.

Ten girls and 13 boys with mean age 11 years when sustaining a fracture of the olecranon were examined at a mean of 19 years after the injury. Ten fractures were displaced less than 2 mm, three 2-3 mm, eight more than 3 mm and two were multifragmental. The treatment consisted of mobilization in three cases, plaster treatment in nine and open reduction and internal fixation in 11 cases. At follow-up, 21 children had no subjective complaints while two had occasional mild pain. The upper arm circumference was thinner in the former injured extremities than in the uninjured (P<0.05). No other objective deficits were found. None had developed non-union or elbow osteoarthritis. Olecranon fractures during growth have an excellent long-term outcome.
